[Retinal detachment following YAG laser section of vitreous strands. Apropos of 3 cases].

PURPOSE: Retinal detachment after Nd: YAG laser vitreolysis is rarely reported. The pathogenic role of Nd: YAG laser is analyzed from 3 cases of severe retinal detachment. METHODS: Three men aged (40 to 59 years old) had one or more risk factors for retinal detachment: myopia, complicated cataract surgery, personal or family history of retinal detachment. Nd: YAG laser treatment onto vitreous strand was performed because of: retinal traction, repeated vitreous hemorrhage, anterior vitreous strand in a aphakic patient with cystoid macular edema. Within six weeks following Nd: YAG laser vitreolysis, severe retinal detachment with several tears occurred, complicated with proliferative vitreoretinopathy in two patients, and with choroidal hemorrhage in one. In two cases, several surgical procedures with silicon oil were required and visual acuity remained under 20/1000. In the last case retinal reattachment was obtained with scleral buckling and cryopexy, the patient recovered a visual acuity of 20/100 with a macular pucker. DISCUSSION: Retinal detachment occurred shortly after laser YAG vitreolysis. We assumed Nd: YAG laser was possibly responsible and investigated the possible mechanisms: direct retinal tear, vitreous strand traction, side effect of intraocular shock wave. CONCLUSION: Nd: YAG laser vitreolysis seems to be able to cause retinal detachment. Its use is therefore not recommended, particularly in patients at risk, especially since the efficacy of this treatment has not been proved.

Treatment of idiopathic exudative retinal detachment.

Three patients with idiopathic exudative retinal detachment are presented. Fluorescein angiography and/or angioscopy was used in each case to demonstrate an area of leakage from the choroid into the subretinal space, accounting for the detachment. The leakage sites were treated by cryopexy or photocoagulation, resulting in reattachment of the retina in each case (four eyes). This method of examination and treatment should be considered in all cases of idiopathic exudative retinal detachment.

Silicone assisted, argon laser confinement of recurrent proliferative vitreoretinopathy related retinal detachment: a technique to allow silicone oil removal in problem eyes.

AIMS/BACKGROUND: Recurrent peripheral retinal detachments may occur in eyes treated with vitrectomy and silicone oil for retinal detachments complicated by proliferative vitreoretinopathy (PVR). The aim of this study was to assess whether laser photocoagulation could be used in the presence of silicone oil to confine and stabilise recurrent PVR related peripheral retinal detachments enabling the timely removal of the oil. METHODS: 10 patients with recurrent peripheral retinal detachments after vitrectomy and silicone oil insertion were treated with posturing and subsequent focal argon laser to circumscribe the area of recurrent detachment. RESULTS: This technique alone was sufficient to limit the area of retinal detachment in seven of the cases. The remaining three cases required relieving retinotomies because of increasing retinal detachment despite the laser. In all 10 cases the silicone oil was later removed without progression of the detached areas. CONCLUSION: Silicone assisted argon laser 'confinement' can be effective in stabilising eyes with peripheral retinal detachments allowing the subsequent removal of silicone oil.

[Vitrectomy for pseudophakic retinal detachment].

OBJECTIVE: To study the method of vitrectomy for treatment of pseudophakic retinal detachment. METHODS: 32 pseudophakic retinal detachment eyes were treated with vitrectomy, primary vitrectomy in 11 eyes (34.4%), vitrectomy after conventional buckling failure in 21 eyes (65.6%), combined with silicone oil 10 eyes (31.3%), removal of intraocular lens 12 eyes (37.5%). All eyes had passed the 6 months to 5 years of follow-up examination. RESULTS: Intra-operative new retinal breaks were identified in 7 eyes (21.9%). The retinal total reattachment was in 25 eyes (78.1%); part reattachment was in 4 eyes (12.5%), and their visual acuity was improved than that before the operation. Due to severe proliferative vitreoretinopathy (PVR), failure occurred in 3 eyes. CONCLUSIONS: The main advantage of vitrectomy is the better intra-operative sight to the peripheral retinal breaks, removal of retinal traction and the low rate of PVR after vitrectomy. Vitrectomy for complicated type of pseudophakic retinal detachment can improve the success rate of the retinal detachment surgery and the visual acuity outcome.

[Risk factors for surgical failures in rhegmatogenous retinal detachment].

BACKGROUND: The evaluation of further risc factors predesposing failure in retinal detachment surgery than those already known to be associated with PVR was the goal of this retrospective study. PATIENTS AND METHODS: The data from 130 cases with unilateral rhegmatogenous retinal detachment treated initially with buckling procedures, were retrospectively reviewed to investigate pre-, intra- and postoperative factors which may predispose anatomical failure in retinal detachment surgery. None of the selected consecutively operated eyes had risk factors, which have already been associated with an unfavourable outcome, such as the presence of preoperative macular holes, PVR or assumed PVR-inducing factors, such as ocular trauma, giant retinal tears, vitreous hemorrhage, previous vitrectomy, cryopexy and laser photocoagulation. RESULTS: The anatomic success rate after scleral buckling procedures was 78.5% and the overall success rate after multiple surgery including vitrectomy increased to 94.6%. 102 (78.5%) cases, treated with a maximum of two scleral buclking operations were statistically compared to the 28 cases which needed further vitreoretinal surgery. The statistical analysis revealed as preoperative risk factors for failure in rhegmatogenous retinal detachment surgery 1) retinal detachment exceeding two retinal quadrants (p < 0.05) and 2) size of the retinal tear larger than 60 degrees (p < 0.05), whereas postoperative risk factors were 1) presence of subretinal hemorrhage (p < 0.01) and 2) persistent subretinal fluid at least two days after surgery (p < 0.01). Eyes with preoperative visual acuity less than 0.1, pseudophacic eyes with posterior chamber intraocular lenses and eyes with severe intraoperative hypotony also showed a tendency to unfavourable outcome, but without a statistically significant level. CONCLUSIONS: Possible ways of interfering in the retinal reattachment process and the clinical importance of these evaluated factors are discussed. They should be taken in consideration for the prognosis of the postoperative anatomical result and treatment modalities if further surgery is required.

Rhegmatogenous retinal detachment after LASIK for myopia.

PURPOSE: To report the characteristics and incidence of rhegmatogenous retinal detachment in myopic eyes after LASIK. METHODS: The medical records of 49 patients with rhegmatogenous retinal detachment after LASIK were reviewed. The incidence of rhegmatogenous retinal detachment after LASIK was determined and potential risk factors were evaluated. RESULTS: LASIK was performed on 59,424 eyes with spherical equivalent refraction (SE) ranging from -0.75 to -26.50 diopters (D) (mean: -6.10 +/- 3.5 D). Forty-nine eyes developed rhegmatogenous retinal detachment between 1.5 and 76 months (mean: 27.3 +/- 21.7 months) after LASIK. The mean preoperative refractive error in these eyes was -8.6 +/- 3.9 D. Mean age of these patients was 38.2 +/- 11.2 years. Thirty-five (71.4%) patients were male. The cumulative incidence of rhegmatogenous retinal detachment was 0.082% (95% confidence interval [CI]: 0.061-0.109), and the yearly incidence was 0.032% (95% CI: 0.023-0.042) after LASIK. The most frequent location of the retinal breaks was the superior temporal quadrant (22.7%). Male sex, older age, and higher preoperative myopia were significantly related to the incidence of rhegmatogenous retinal detachment after LASIK (P<.001). CONCLUSIONS: Based on the results of this study, following the treatment of high-risk peripheral retinal lesions, LASIK did not appear to be an additional risk factor for the development of rhegmatogenous retinal detachment after LASIK in our patients; however, patients should be informed of the possibility of this complication as a consequence of myopia. Patients who are male, older in age, and have high myopia preoperatively may be at increased risk.

Computed tomography of the nonrhegmatogenous retinal detachment in the pediatric patient.

Nonrhegmatogenous retinal detachments occur in the pediatric population secondary to other ocular disorders. The most important cause to identify is retinoblastoma. Computed tomography has proven to be the most reliable ancillary diagnostic test in this pediatric population. A series of eighty patients, presenting with nonrhegmatogenous retinal detachments, was examined. The role of computed tomography and characteristic clinical findings are discussed.

Spontaneous regression and disappearance of subclinical rhegmatogenous retinal detachment.

PURPOSE: To report spontaneous regression and disappearance of subclinical rhegmatogenous retinal detachment. METHODS: Case reports. RESULTS: Three separate areas of subclinical retinal detachment in two eyes of two patients were followed without treatment for 35 years (Case 1) and 28 years (Case 2). The three areas of subclinical retinal detachment spontaneously regressed and disappeared. There has been no recurrence of subclinical retinal detachment in Case 1 for 12 years and 14 years, and in Case 2 for 12 years. CONCLUSION: Subclinical retinal detachment can show spontaneous regression and disappearance as its natural outcome when observed without intervention.

[Post-traumatic retinal detachment in children under 15 years of age].

In less than 15 years old children 33 post-traumatic retinal detachments were operated during these last four years (postocular wound retinal detachment with or without intraocular foreign body, post contusion retinal detachment). A very close posterior pole monitoring of these high risk eyes is mandatory to prevent late diagnosed retinal detachments. The post-contusion retinal detachment surgery good results are quite opposite to the bad results of the postocular injury retinal detachment with intraocular foreign body and secondary proliferative vitreoretinopathy. These retinal detachment severity must lead to a strict prophylactic laser therapy of all the traumatic eyes.

Frequency of ciliary body or retinal breaks and retinal detachment in eyes with atopic cataract.

AIM: To determine the frequency of ciliary body or retinal breaks and retinal detachment in eyes with atopic cataract. METHODS: The records of 106 eyes (74 patients) with atopic cataract that underwent cataract extraction were reviewed. The frequency of ciliary body or retinal breaks and retinal detachment was classified by their presence preoperatively and postoperatively, and by cataract type. RESULTS: Breaks were detected preoperatively in 27 eyes (25.5%) of 17 patients in the ciliary body (20 eyes, 18.9%), near the ora serrata (five eyes, 4.7%), and in undefined locations (two eyes, 1.9%). Among these, 16 eyes (15.1%) had already developed retinal detachment. After surgery, a ciliary body break occurred in one eye (0.9%) and retinal detachment in four eyes (3.8%) of three patients. The breaks that caused postoperative retinal detachment were in the ciliary body. When classified by cataract type, the highest frequency of breaks was associated with mature cataracts (35.0%), and all eyes with breaks developed retinal detachment. CONCLUSIONS: One fourth of eyes with atopic cataract had breaks in the ciliary body or ora serrata, or retinal detachment preoperatively. The highest frequency of either breaks or retinal detachment was associated with mature cataract. The frequency of breaks or detachment that occurred postoperatively (approximately 5%) was lower than that present preoperatively.

[Retinal detachment by inferior tear: a poor prognosis?].

AIM: To determine whether a lower location of retinal wounds is a factor for poor prognosis in retinal detachment. PATIENTS AND METHOD: This retrospective study involved 248 medical records of patients who were operated on for retinal detachment in 2001 at the Toulouse-Rangueil Hospital Ophthalmology Department. We excluded retinal detachment of very short-sighted patients, diabetic patients and detachment secondary to trauma or relapses. We compared the incidence of surgical failure according to various parameters: condition of the crystalline lens, operative technique, operator, vitreoretinal proliferation, retinal wound location, patient age and the operative side. Thirty-six patients presented with lower wounds; 17 patients obtained incomplete results and relapsed within 1 year of surgery. RESULTS: Vitreoretinal proliferation and inferior location of the retinal detachment were found to be poor prognostic factors. No significant differences were found between the other parameters studied. DISCUSSION: A variety of prognostic factors of retinal detachment surgery are now clearly identified (vitreoretinal proliferation, old detachment). A lower location of the detachment constitutes an additional difficulty for retinal applications. Indeed, it is more difficult to perform effective buffering in this type of case. We recommend that retinal detachment be operated internally, to reduce the risk of relapse. CONCLUSION: An inferior location of the retinal wound during retinal detachment appears to be a factor of poor prognosis, but this remains to be ascertained through an ongoing, prospective study.

[Surgical prevention of retinal detachment].

Prophylaxis of rhegmatogenous retinal detachment consists of measures both non surgical and/or surgical that are effective in preventing some risk-factors that are part of the disease. The procedure must avoid any types of danger. This paper describes a new reliable surgical procedure of circular buckling used for prophylaxis on predisposed fellow-eye of giant retinal tear.

Bilateral retinal detachments in thrombotic thrombocytopenic purpura.

Bilateral serous retinal detachments are rare complications of thrombotic thrombocytopenic purpura (TTP). We report the case of a 28-year-old woman with chronic relapsing TTP with bilateral serous retinal detachments, which resolved after prompt aggressive medical therapy. Unlike several previous reports, the retinal detachments in our patient were unrelated to systemic hypertension.

Active immobilization of the eye in the treatment of retinal detachment.

40 eyes with retinal detachment were immobilized by traction sutures under the inferior and medial rectus muscles in order to study the rate of "spontaneous" reattachment following such fixation. There was an almost complete reattachment in 45% of cases, and partial reattachment (at least half of the detached area) in 40%. Little or no reattachment was observed in 15% of cases. Reattachment of the retina prior to the operation is considered advantageous for the success of surgery.

Strabismus after retinal detachment surgery.

Strabismus after retinal detachment surgery is temporary in most cases. Long-term diplopia, however, is seen in 5% to 25% of patients. In most cases the cause is restrictive strabismus due to adhesions, muscle fibrosis, or scarring involving the buckling material. Deviations due to direct muscle injury and "sensory" deviations due to poor vision also occur. Nonsurgical treatments include prisms and botulinum toxin injections. Surgical intervention using adjustable sutures is successful in most cases.

[Postoperative complications with the use of implants for treatment of retinal detachment].

Complications of the retinal detachment surgery with the use of episcleral and intrascleral implants are presented. The authors are using biological materials (fascia lata, dura mater) as well as alloplastic materials (Lincoff's sponge). Among the postoperative complications following were seen: protracted reactions from the side of the ocular adnexa, intraocular haemorrhages, intravitreal exudates. The most severe from the observed complications was the atrophy of the sclera at the spot of implantation of the silicon sponge.

Retinal pigment epithelium melanin granules are phagocytozed by Müller glial cells in experimental retinal detachment.

The ability of retinal Müller glial cells to perform phagocytosis in vivo is studied in a rabbit model of experimental retinal detachment where pigment epithelial cells are occasionally detached together with the neural retina. While macrophages and/or microglial cells phagocytoze most of the cellular debris at the sclerad surface of the detached retinae, some Müller cells accumulate melanin granules. The granules are virtually intact at the ultrastructural level, and are surrounded by a membrane. They are often located close to the sclerad end of the cells, but some are distributed throughout the outer stem process up to the soma. It is concluded that rabbit Müller cells in vivo are capable of phagocytosis and of transporting the phagocytozed material within their cytoplasm.
