Pericranium grafts for exposed orbital implants.

PURPOSE: To report the use of autologous pericranium grafts to cover exposed orbital implants. METHODS: A two-center consecutive case series of exposed orbital implants covered with autologous pericranium grafts. A patch of pericranium was harvested from the parieto-occipital region and was placed over the implant within a pocket between the implant and the Tenon capsule, followed by layered closure of Tenon and conjunctiva. RESULTS: Four patients (2 women, 2 men) with a mean age of 37 years (range, 26 to 45 years) were included in the study. The mean follow-up period was 9.5 months (range, 7 to 12 months). In all cases, there was no recurrence of exposure and no donor site morbidity. A small pyogenic granuloma, arising from the conjunctival suture line, developed in one case. CONCLUSIONS: Autologous pericranium is a useful covering material for exposed orbital implants and may be used as an alternative to frontal periosteum.

Globe perforation associated with subtenon's anesthesia.

PURPOSE: To report a case of globe perforation while initiating posterior subtenon's anesthesia. METHODS: Case report. A 40-year-old man with a history of retinal detachment in both eyes presented for repair of a second retinal detachment in the LE. RESULTS: Upon dissecting a space beneath the Tenon capsule with scissors, the globe was perforated. CONCLUSION: In patients with prior ophthalmologic surgery, thinned sclera, or excess scar tissue, increased caution should be employed during initiation of sub-Tenon anesthesia or an alternative method should be used.

Latanoprost stimulates secretion of matrix metalloproteinases in tenon fibroblasts both in vitro and in vivo.

PURPOSE: To investigate the presence and the possible role of different matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) in Tenon capsule fibroblasts. These enzymes are essential for the control of tissue remodeling in the context of wound repair. This aspect is important to further the understanding of and possibly to influence the scarring process of filtering blebs after glaucoma surgery. METHODS: Untreated and latanoprost-treated human Tenon fibroblasts were examined for the presence of MMPs and TIMPs on the mRNA and protein levels. Assays performed included RT-PCR, real-time RT-PCR, immunocytochemistry, Western blot analysis, flow cytometry, and zymography. To investigate the changes in vivo, conjunctival specimens of rabbits treated with latanoprost eye drops were examined by immunohistochemistry. RESULTS: In all assays, both MMP-3 and TIMP-2 were detected. With the real-time RT-PCR technique, MMP-1, -2, -3, -7, -9, and -14 and TIMP-1 and -2 were detected. An upregulation of MMP-3 and TIMP-2 after latanoprost treatment of the fibroblasts was shown and found to occur on the mRNA and the protein levels. The upregulation of MMP-3 and TIMP-2 was confirmed in vivo. CONCLUSIONS: Tenon fibroblasts contain the ability on the mRNA level to synthesize all enzymes of the MMP and TIMP family that are related to remodeling of the extracellular matrix. The levels of MMP-3 and TIMP-2 increase after treatment with latanoprost. Tenon fibroblasts may be the target cells for attempts to influence the tissue levels of MMPs and TIMPs in the context of conjunctival wound healing after glaucoma surgery.

Primary placement of a motility coupling post in porous polyethylene orbital implants.

The placement of a motility coupling post (MCP) to integrate the prosthesis with a porous orbital implant may enhance prosthetic motility following enucleation. Previously, MCP placement has required a second operation usually at least 6 months following enucleation. We developed a technique to place an MCP reliably and safely into a porous orbital implant at the time of enucleation. Eligibility criteria included high motivation to achieve maximal prosthetic motility, adequate conjunctiva to ensure desirable wound closure, and isolation of the 4 rectus muscles. Enucleation was performed in standard fashion with implantation of a conical porous polyethylene orbital implant. Implanted MCPs protruded anteriorly 2 to 4 mm. The Tenon capsule and conjunctiva were closed in separate layers over the protruding MCP. Thirty-two patients underwent primary placement. Follow-up ranged from 1 to 33 months (mean, 15 months). Nine MCPs spontaneously exposed within the first 4 months. One additional post autoexposed at 12 months. Three patients underwent a secondary procedure to expose the MCP. There were no cases of infection, explantation, or gross MCP malposition. Minor complications included pyogenic granuloma (n=2) and conjunctival overgrowth (n=1). All patients were successfully fit with prostheses. Prosthetic motility was acceptable in all patients. Motility coupling post placement at the time of enucleation surgery in selected patients is an effective, efficient surgical option. Arch Ophthalmol. 2000;118:826-832

Interpolated conjunctival pedicle flaps for the treatment of exposed glaucoma drainage devices.

OBJECTIVE: To describe an alternative method to repair exposed glaucoma drainage devices (GDDs) when conventional attempts have failed. METHODS: Four eyes, from 3 patients, with severe ocular surface disease were included in the study. All eyes had previously received a Baerveldt GDD for uncontrollable intraocular pressure and postoperatively had exposed GDDs. The conjunctival defects were unrepairable with a scleral patch or pericardium, conjunctival advancement, or a conjunctival patch graft. Two eyes had chemical burns, one eye had extensive scarring from multiple surgical procedures, and one patient had rheumatoid arthritis. Each patient provided informed consent, and was given the option of removing the GDD and undergoing diode cyclophotocoagulation or attempting to save the GDD by a conjunctival pedicle flap. An interpolated conjunctival pedicle flap was taken from the cul-de-sac (fornix). The conjunctiva and Tenon capsule were incised radially to the tube, rotated from the fornix at a 90 degrees angle, and sutured to the remaining healthy conjunctiva to cover the exposed tube. RESULTS: Postoperatively, all eyes had vascularized flaps that showed viable tissue. All eyes retained the GDDs, and the intraocular pressure has been under control during follow-up (7, 13, 25, and 27 months). CONCLUSION: Interpolated conjunctival pedicle flaps seem to be a viable alternative to repairing exposed GDDs when other methods are impractical or impossible.

Idiopathic orbital inflammation: distribution, clinical features, and treatment outcome.

OBJECTIVE: To evaluate the distribution and clinical as well as treatment outcome characteristics of idiopathic orbital inflammation with the aim of delineating a more systematic approach to diagnosis and treatment. METHODS: A 10-year retrospective review of patients with idiopathic orbital inflammation treated at one institution. RESULTS: Ninety eyes in 65 patients (22 men and 43 women) were studied. Diagnoses were isolated dacryoadenitis (n = 21), isolated myositis (n = 19), concurrent dacryoadenitis and myositis (n = 5), orbital apex syndrome (n = 6), and idiopathic inflammation involving the preseptal region, supraorbital region, sclera, Tenon capsule, orbital fat, or optic nerve (n = 14). The mean age at presentation was 45 years. Pain and periorbital swelling were the most common clinical features and were observed in 45 (69%) and 49 (75%) patients, respectively. Seventeen patients (26%) had bilateral involvement. Biopsy was performed in 19 patients (29%) with atypical presentations or who failed to respond to the initial therapy. Patients were treated with steroids alone (n = 45), steroids and subsequent radiation therapy (n = 8), steroids and nonsteroidal anti-inflammatory agents (n = 6), nonsteroidal anti-inflammatory agents alone in mild cases (n = 2), and, rarely, radiation therapy without steroids (n = 1) or surgical debulking alone (n = 1). Of 65 patients, 41 (63%) represented treatment successes, with complete symptom relief at the time of the last follow-up, and 24 (37%) represented treatment failures, with partial or no relief of symptoms. Treatment failures were often characterized by recurrence of inflammation after a period of quiescence (58%) and unremitting, recalcitrant inflammation (38%); 1 patient ultimately required an exenteration. CONCLUSION: Systemic steroid with a slow taper has been the established first-line treatment for idiopathic orbital inflammation, but refractory cases accounted for a significant portion of treatment failures in our study, reflecting the need for a more systematic approach to the study of this multifaceted disease and for therapeutic alternatives to systemic steroids.

Surgical reduction of symptomatic, circumferential, filtering blebs.

We describe methods and outcomes of surgical reduction of symptomatic, circumferential, filtering blebs after trabeculectomy with antifibrotic agents. The medical records of 15 eyes of 14 patients with symptomatic, circumferential blebs who underwent surgical bleb reduction for bleb dysesthesia under topical anesthesia were reviewed. Each bleb was incised segmentally and the cut edges of the conjunctiva and Tenon capsule were sutured to the underlying sclera. Outcome measures included symptomatic relief, retention of bleb function, and intraocular pressure maintenance. Fourteen eyes had successful reduction of bleb size, symptomatic relief, and cosmetically acceptable appearance. One eye continued to have dysesthesia and 1 had a transient bleb leak that resolved spontaneously. Surgical reduction of circumferential, symptomatic, filtering blebs is a safe and effective technique to reduce bleb dysesthesia and improve cosmesis without loss of bleb function.

Closed vitreous surgery: XV. Fibrovascular ingrowth from the pars plana sclerotomy.

Ten eyes developed fibrovascular ingrowth from the sclerotomy following closed vitreous surgery. The complication was detected by examining all patients postoperatively by indirect ophthalmoscopy and biomicroscopy with a three-mirror lens. The average follow-up was 13.2 months. Nine patients had proliferative retinal disease prior to surgery and related systemic disease. In six eyes, useful vision was lost due to the ingrowth. In three eyes, a stabilization occurred. In one eye, that of a 12-year-old girl with an undefined syndrome of cochlear and retinal neovascularization, the ingrowth involuted. Rubeosis iridis was observed in 6 eyes that developed vascular ingrowth as opposed to 11 eyes in a control group of 78 eyes. Eyes with rubeosis iridis should not have vitreous surgery, and careful dissection of the Tenon capsule should be done over the sclerotomy.

Prognosis and risk factors for early postoperative wound leaks after trabeculectomy with and without 5-fluorouracil.

PURPOSE: To evaluate the prognosis of patients who develop early postoperative wound leaks after trabeculectomy, to determine risk factors for these leaks, and to document adverse outcomes. DESIGN: Multicenter randomized clinical trial. METHODS: Two-hundred thirteen patients with previous cataract surgery or failed filtering surgery were randomized to either trabeculectomy (standard group) or trabeculectomy with postoperative subconjunctival 5-fluorouracil injections (5-FU group). Masked measurements of intraocular pressure were performed throughout 5 years of follow-up. Failure was defined as a reoperation to control intraocular pressure or an intraocular pressure greater than 21 mm Hg with or without medication at or after the 1-year examination. An early postoperative wound leak was defined as one that developed within 2 weeks postoperatively, determined by daily topical fluorescein testing. RESULTS: At 1 year (5 years), the success rate for the 5-FU group was 80% (54%) in eyes without a leak, and 60% (28%) in those with a leak. The 1-year (5-year) success rate in the standard group was 50% (24%) in those without a leak and 44% (15%) with a leak. (P =.018, log-rank test, adjusted for treatment). Leaks were more common in the 5-FU group, 34/105 (32%), than in the standard treatment group, 22/108 (20%), (P =.066, chi(2)). More eyes with one-layer conjunctiva-Tenon capsule closure developed leaks 40/115 (35%) than those with two-layer closure 16/95 (17%) (P =.006, chi(2)). More eyes with a trabeculectomy located inferiorly 29/76 (38%) developed leaks than those done superiorly 27/137 (20%) (P =.006, chi(2)). Patients with leaks were older (66 years) than those without leaks (60 years) (P =.011, t test). CONCLUSION: An early postoperative wound leak was a risk factor for trabeculectomy failure. We recommend that trabeculectomy be performed in a superior location with a two-layer closure.

Primary placement of a titanium sleeve in hydroxyapatite orbital implants.

BACKGROUND: To study a new surgical option of primary placement of a titanium sleeve into hydroxyapatite implants during enucleation or evisceration. METHODS: A standard enucleation or cornea preserved evisceration was performed, followed by preplacement of a titanium sleeve into the hydroxyapatite implant by a hand drill sleeve driver. Care must be taken to ensure that the titanium sleeve is positioned centrally when the implant is put inside the orbital socket or eviscerated shell. The Tenon capsule and conjunctiva were meticulously closed with minimal tension. Complications such as sleeve exposure, coralline exposure, and infection of the titanium sleeve were closely observed. RESULTS: In all, 30 patients were treated in the above fashion with 10 enucleation and 20 evisceration procedures. The follow-up period ranged from 9 to 24 months. Three of the sleeves were found to have exposed spontaneously at 5 and 7 weeks following original surgery. They had no further complication except one sleeve loosening. The remaining 27 sleeves that did not spontaneously expose pursued secondary exposure of the titanium sleeve and peg insertion by conjunctival cutdown procedure 3 months after original surgery. Two sleeves were found to be oblique positioned after the conjunctival cutdown procedure. Fortunately, all the 30 patients were successfully fit with a peg-coupled prosthesis with good motility. CONCLUSION: Primary placement of a titanium sleeve into hydroxyapatite implants has several advantages, including high patient acceptance, technical simplicity, and office-based conjunctival cutdown pegging procedure. By avoiding the expense of postoperative imaging study and additional prosthetic modification, a more rapid and efficient rehabilitation is possible.

High-resolution magnetic resonance imaging of the orbital connective tissue system.

A complex system of connective-tissue septa within the orbit has previously been described in serial histologic sections. The present study describes the anatomy of the orbital connective tissue system on high-resolution magnetic resonance (MR) images in vivo. Five volunteers aged 26 to 35 year underwent magnetic resonance imaging of the orbit on a 1 Tesla unit (Impact, Siemens, Germany). T1-weighted coronal images were obtained using a surface coil. Anatomical structures on the MR images were identified by comparison with corresponding histologic sections. On MR images of the anterior orbit, the levator aponeurosis, Lockwood ligament, transverse intermuscular ligament, common sheath, check ligaments, Tenon capsule, intermuscular septa, and palpebral ligaments can be seen. In the mid- and posterior orbit, the intermuscular orbital septa, especially the superolateral septum, the superior ophthalmic vein hammock, and septa of the radial connective tissue system are visualized. High-resolution magnetic resonance imaging is capable of delineating the major septa of the orbital connective tissue system.

The use of vicryl mesh in 200 porous orbital implants: a technique with few exposures.

PURPOSE: To report the results of a wrapping technique for porous orbital implants by using polyglactin 910 (Vicryl) mesh (Ethicon Inc., Somerville, NJ, U.S.A.). METHODS: We retrospectively reviewed the records of 200 consecutive patients from one author's practice who received a polyglactin 910 mesh-wrapped porous orbital implant after enucleation or as a secondary implant between October 1, 1996, and April 15, 2001. We recorded potential problems that might be attributed to polyglactin 910 mesh both before pegging (excessive inflammatory response to the material, conjunctival thinning, and implant exposure) and after pegging (exposure of the implant around the sleeve, conjunctival thinning, and implant exposure other than adjacent to the peg). RESULTS: One hundred twenty-two men and 78 women underwent placement of a polyglactin 910 mesh-wrapped porous orbital implant. The average age at the time of implantation was 48.9 years (range, 11 to 85 years). The average follow-up interval in the 200 patients was 19.4 months (range, 2 to 80 months). Thirteen of the 200 patients had less than 6 months of follow-up, leaving 187 patients with an average follow-up of 20.5 months (range, 6 to 80 months). There were 76 primary enucleations and 124 secondary orbital implants. Thirty-seven patients received a Bio-Eye hydroxyapatite implant (HA) (Integrated Orbital Implants, San Diego, Calif), 97 received a synthetic FCI hydroxyapatite implant (FCI, Issy-Les-Moulineaux, France), and 66 received a Bioceramic implant (aluminum oxide-Al2O3) (FCI, Issy-Les-Moulineaux, France). One hundred fourteen patients (57%) underwent peg placement. The average time to pegging was 9.9 months (range, 6 to 16 months). Before pegging, 4 of 187 patients (2.1%) had implant exposure. Three of these exposures followed secondary orbital implant placement (2 Bio-Eye HA, 1 synthetic FCI3 HA) and one followed an enucleation (synthetic FCI3 HA). Two patients required a temporalis fascia graft and one required a scleral patch; the remaining defect closed spontaneously. One patient had conjunctival thinning 6 months after orbital implantation, which remained stable with no frank exposure for 36 months. No patient had excess socket inflammation. After peg placement, 3 additional patients had exposure of the implant around the peg site. There were no cases of conjunctival thinning or exposure of the implant other than adjacent to the peg site. CONCLUSIONS: Polyglactin 910 mesh is an excellent option as a wrapping material for porous orbital implants. It is simple to use, readily available, eliminates the need for donor tissue, does not require a second operative site, and it is less expensive than other currently available wrapping materials. We attribute our high success rate to our technique, which emphasizes proper placement of the implant within the Tenon space, suturing the extraocular muscles anterior to their normal anatomic sites, and meticulous closure of the Tenon capsule and conjunctiva in separate layers.

[Use of "low dose" 5-fluorouracil during trabeculectomy].

PURPOSE: This retrospective study was undertaken to evaluate if a "low dose" intraoperative sponge 5-fluorouracil application may improve the quality of the postoperative IOP control without increasing the incidence of postoperative complications following a first trabeculectomy in low-risk and/or severe field defects glaucomatous patients comparatively with a control group. MATERIAL-METHOD: Our study included a total of 41 trabeculectomies performed in 39 patients. An intraoperative sponge 5-FU application (10 mg/ml) was performed during a mean duration of one minute in 28 trabeculectomies. Mean follow-up was 10.1 +/- 5.6 months (range: 3 to 24 months) and was comparable in 5-FU and control group. Mean age of patients (62.9 +/- 11.4 years) was not significantly different in both groups as well as their preoperative mean visual acuity, the severity of their visual field defects, the importance, the nature of preoperative topical medications and the number of sutures in scleral flap during trabeculectomy. The thickness of Tenon capsule was only significantly different in the two groups (p < 0.05). Our success criteria were based on a "target" IOP reached in the last examination with or without adjunctive medical treatment. RESULTS: Mean preoperative IOP was 32.2 +/- 8.4 mm Hg and was reduced in the last control to a mean value of 14.4 +/- 4.0 mm Hg without any significant difference between the 5-FU group and the control group (p > 0.05). The rate of failures was higher in the control group (15.3%) than in the 5-FU group (7.1%) in the last examination. Significantly more eyes (31%) in the control group required adjunctive postoperative medication than in the 5-FU group (3%) in the last follow-up. The incidence and severity of complications were not significantly different in both groups. Postoperative 5-FU injections were performed in a non significant different number of eyes in one group comparatively with the other. Morphologic characteristics of filtration blebs were comparable in the two groups. CONCLUSION: A "low dose" intraoperative 5-FU sponge application during a first trabeculectomy in low-risk patients and/or in patients with severe field defects in whom a low-ten target IOP is mandatory, seems to improve the postoperative IOP control without increasing the incidence of postoperative complications.

[Mitomycin C in glaucoma surgery].

Glaucoma filtering surgery fails because of scarring of the filtering bleb. Fibroblasts proliferation from the episclera and Tenon capsule play an important role in the scarring process. The use of antimetabolites in glaucoma filtering surgery have a beneficial effect on the lowering of intraocular pressure especially in eye at poor surgery prognosis. They inhibit the fibroblasts proliferation and subsequent scarring of filtering bleb. 5 fluorouracil improves chance of success with filtering surgery but the necessity of multiple subconjunctival injections has many disadvantages including discomfort for the patient and ocular surface problems such as corneal defect and conjunctival wound leak. Mitomycin C with its focal applications limits the toxic effects to tissue directly exposed to the drug. A single intra-operative application leads to a more hypotensive effect with less corneal complications which are two major advantages of this treatment (Kitazawa and al.): Success rate at one year without medical treatment: 88% with MMC-40% with 5 FU. Different tissue culture studies as well as clinical studies demonstrate that the antiproliferative effect of MMC is 100 times more powerful than 5 fluorouracil. Mitomycin C might probably interfere with other steps in the wound healing process. Mitomycin C seems to be a better treatment than 5 fluorouracil. Nevertheless long term randomized prospective human studies are necessary to confirm it.

Modifications of and special operating tricks in the classical technique of surgery against strabismus.

Even nowadays the idea of most of the operations against strabismus is based on myectomy and reposition of the rectus muscles. At the Department of Ophthalmology of the University Medical School of Debrecen we use mainly these two methods of operation. At our Department we performed 1605 operations against strabismus during the last 10 years. 1269 of our patients had convergent, 336 had divergent strabismus. The majority of the operations were performed on patients less than 6 years of age, under general anesthesia. The outcome of the operation is successful if it results in a situation, in which torque affecting the eyeball stabilizes it in the normal position. The advantage of the combined surgical procedure is that the former muscular balance remains intact, and by relatively small intervention good results can be achieved. In the rectus muscles of squint patients anatomical and histopathological changes could be found, especially if they did not receive pleoptic treatment preoperatively. Depending on the direction of the strabismus one of the muscles is thicker, while the other is thinner, due to hyper- and hypofunction. Our surgical experience of many years showed that by modifying the classical technique of the operations with some fine technical tricks it was possible to increase the success rate. In our film we presented the right way of incising and handling the subconjunctival connective tissue (Tenon capsule) thus making it possible to lay it back to its original place at the end of the operation. This way the chance of postoperative scarring is reduced. We demonstrated how to test the contractility of the muscles by using muscle-hooks, that replaces the forceps test. In case of myectomy we demonstrated the tricks of how to handle the easiest and the finest way. In case of retroposition we can achieve perfect reconstruction and wound healing by using the shown simple technique. We also take much care of suturing the conjunctiva during operations performed on infants that is important because of their undisciplined behavior.

Connective tissue of the orbital cavity in retinal detachment: an ultrastructural study.

The connective tissue from Tenon's capsule of 7 patients who underwent surgery for retinal detachment was studied ultrastructurally. Five patients were 58-70 years old, and 2 were young adults. The Tenon capsules of 6 children and of 2 aged patients without retinal problems were used as controls. In young controls the Tenon capsule was composed mainly of round, smooth collagen fibrils and a few elastic fibers. The collagen fibrils varied in size from 70 to 110 nm. In the aged patients with retinal detachment, the collagen fibrils showed marked variation of size and also abnormalities of shape in 4 out of 5 cases. The diameter of collagen fibrils varied from 32 to 160 nm, and the elastic fibers were fewer as compared with controls. The possibility arises that age-related structural changes of the orbital connective tissue could predispose to retinal detachment.

Effect of bile acids on fibroblast proliferation and viability.

PURPOSE: To examine the in vitro effects of bile acids and salts on the viability, growth and morphology of human Tenon's capsule fibroblasts. METHODS: Human Tenon's capsule fibroblasts were grown from explants in culture and used between passages 3 and 5. Fibroblasts (n = 3) were treated in triplicate with deoxycholic acid (DA), sodium deoxycholate (NaD) and cholic acid (CA) at concentrations between 50 microM and 1 mM. Cell viability and growth were assessed with trypan blue staining and haemocytometer counting, and a colorimetric (MTT) assay. Morphology was assessed with light microscopy and cresyl violet staining. RESULTS: A dose-dependent decrease in viability was observed following bile acid treatment (24 and 48 h) where the effects of DA > NaD > CA. The LD50 values at 48 h for DA, NaD and CA were 300 microM, 400 microM and 720 microM respectively. Cell growth following bile acid treatment was reduced compared with controls. Fibroblasts treated with bile acids displayed a loss of normal spindle-shaped morphology and multiple processes, some with varicosities, extended from many cells. These changes were dose-dependent, and at higher concentrations cells became detached and were non-viable (trypan-blue-positive). Extensive cell death was observed in cultures treated with DA 400 microM, NaD 500 microM and CA 800 microM. CONCLUSIONS: Lower doses of bile acids and salts reduced in vitro fibroblast growth associated with morphological changes; higher doses induced fibroblast cytotoxicity. These observations suggest that bile acids and salts, in particular DA, may be useful in regulating wound fibrosis following trabeculectomy surgery.

Complications of dermis-fat orbital implantation.

Primary dermis-fat implantation can be effectively performed in cases without pre-existing systemic vascular disease or orbital burns. Meticulous handling of the graft (using a Goeller trephine and Tenon's capsule traction sutures), filleting Tenon's capsule, and avoiding cautery of the graft bed may minimize graft necrosis and atrophy. Pyogenic granulomas of the conjunctival-graft interface and graft hirsutism are easily managed. Keratinization of the socket, graft wound dehiscence, donor site hematomas, and wound dehiscence are avoided with careful surgical technique. Secondary dermis-fat orbital implantation may add orbital volume and conserve the conjunctival fornices, but may also suffer a slightly increased frequency and amount of graft absorption.
