Tissue plasminogen activator irrigation to facilitate removal of subretinal hemorrhage during vitrectomy.

I report removing a large submacular hemorrhage by means of vitrectomy combined with use of tissue plasminogen activator (tPA) to facilitate clot removal. Four months postoperatively, the vision was 20/100 and the retina was flat, with a very thin layer of residual hemorrhage and pigmentary alteration in the macula. Although the long-term prognosis is guarded, this case does suggest that tPA may be a useful adjunct in managing selected cases of subretinal hemorrhage associated with macular degeneration.

Pars plana vitrectomy for ocular complications of Behçet's disease.

BACKGROUND AND OBJECTIVES: To evaluate the outcomes of vitreoretinal surgery for the ocular complications of Behcet's disease. PATIENTS AND METHODS: This retrospective study included 20 eyes of 15 patients with Behçet's disease (9 men, 6 women; mean age at surgery, 31.0 +/- 1.8 years; range, 21-44 years) who had undergone vitreoretinal surgery for Behcet's disease at Ondokuz Mayis University, Faculty of Medicine, Department of Ophthalmology, Samsun, Turkey, between January 2000 and September 2003. Postoperative visual acuity outcome, course of uveitis, and complications were evaluated in all patients. RESULTS: Indications for surgery were vitreous opacities in 10 eyes (50%), cystoid macular edema in 5 eyes (25%), epiretinal membrane in 3 eyes (15%), and vitreous hemorrhage in 2 eyes (10%). At the last postoperative follow-up, visual acuity had increased 2 Snellen lines or more in 10 (50%) of 20 eyes. Cystoid macular edema completely improved in 3 (60%) of 5 eyes after vitrectomy. Uveitis attacks significantly decreased during follow-up (P = .015). Immunosuppressive treatment was stopped in 11 (73%) of 15 patients. Retinal detachment and phthisis were not observed in any eye. CONCLUSION: Vitreoretinal surgery may be useful in the treatment of posterior segment complications of Behcet's disease.

[In vivo observation of crystalline lens changes in the early post-vitrectomy stage].

Crystalline lens changes of 17 cases of eye undergoing simple vitrectomy were observed from the post-operative 1st to 21st month. Changes in the crystalline lenses were detected through a slitlamp microscope or by methods of image analysis, the Opacity Lensmeter and the laser scattering spectroscopy. Increases of the scattering light intensity of the anterior and posterior deep cortical layers were observed from the early post-operative stage in 9 cases. Seven cases progressed to nuclear opacification during the observation period, however, one case showed no nuclear changes even at the 12 post-operative month. No relationships were observed between the early cortical changes and surgical invasion, patient age, or cause of vitreous opacification. Quantitative evaluation by image analysis revealed early post-operative crystalline lens changes in cases undergoing vitreous surgery.

[The role of vitrectomy in the treatment of retinal detachment with macular holes].

The authors discuss the pathogenesis and the method of treatment of a retinal detachment with a macular hole basing on personal material and a review of foreign literature. Personal material consists of 11 eyes in 10 patients operated upon in the University Ophthalmic Department in Munich in the period November 1988--April 1990. In all the cases the primary method of treatment based on vitrectomy performed through the pars plana with a gas tamponade. In 4 cases a reoperation with silicon oil tamponade was necessary. Anatomical reattachment of the retina was achieved in 9 among 11 treated eyes. In 10 cases the visual acuity was 1/50 or better. Five among them showed the visual acuity at last 0.1.

Vitrectomy for stage 1 macular holes identified by optical coherence tomography.

BACKGROUND AND OBJECTIVE: To describe a series of patients with decreased vision secondary to stage 1 macular hole confirmed by optical coherence tomography (OCT) that failed to spontaneously resolve with observation. To determine whether current surgical techniques can prevent progression to a full-thickness macular hole and lead to improved visual acuity. PATIENTS AND METHODS: Retrospective, comparative case series presenting patient demographics, duration of symptoms, timing of surgery, preoperative and postoperative vision, and clinical outcome based on examination and OCT. RESULTS: Five eyes of five patients with stage 1 macular holes identified on OCT required surgical repair. All eyes showed anatomic closure and lack of progression to a full-thickness hole confirmed by OCT after one procedure. Mean preoperative visual acuity was 20/102 (range, 20/50 to 20/200) and mean postoperative visual acuity was 20/52 (range, 20/25 to 20/200). Average improvement for all five eyes was 3 Snellen lines, with four of the five (80%) improving 5 lines each. CONCLUSION: In symptomatic eyes with stage 1 macular holes that fail to spontaneously resolve with observation, vitrectomy with intraocular gas tamponade may prevent progression to a full-thickness hole and lead to improved visual acuity.

Results of pars plana vitrectomy in 24 cases of endophthalmitis.

Twenty four cases of endophthalmitis were subjected to pars plana vitrectomy. A final vitreous clearance was obtained in 62.50% cases. Visual improvement occurred in 41.67% cases. It was concluded that prompt detection and early and vigorous therapy--medical and surgical--is the mainstay in the management of endophthalmitis.

[Anterior vitrectomy in the treatment of post-traumatic defects of the eye].

The authors analyse the results of 116 operations in which they performed anterior vitrectomy using the Berkeley's and Opticon vitrectomes. Operations of this type have been performed in cases of traumatic cataract, subluxated and luxated lenses. One removed also post-inflammatory membranes and the vitreous from the anterior chamber and from the area of the wound. The functional and anatomical results have to be acknowledged as satisfactory.

[Pars plana vitrectomy in the treatment of exogenous suppurative endophthalmitis].

The authors evaluate the results of pars plana vitrectomy (PPV) in 12 patients with exogenous suppurative endophthalmitis (EHE). EHE developed after operation of cataract in eight patients and after perforating injury of the sclera in four patients. The shape, size and appearance of the eye was preserved in 11 eyes, the function of the eye with a visual acuity of 0.5-1.0 was saved in six eyes (50%), in one eye with bacteriologically confirmed mycotic enophthalmitis and in five eyes where bacterial infection was assumed. Inoperable detachment of the retina characterized the ophthalmoscopic finding in all eyes with loss of function. Close cooperation of ophthalmological departments with vitreoretinal centres and early performance of urgent surgery are the basic prerequisites of better functional results of PPV in EHE.

[Pars palana vitrectomy in chronic uveitis].

The authors evaluated the results of pars plana vitrectomy (PPV) on account of chronic uveitis in 10 eyes of nine patients. In one patient where both eyes were operated on the cause of uveitis was spondylitis ankylopoietica, in the remainder the cause of uveitis was not revealed. All eyes tolerated PPV well. PPV markedly improved the visual acuity in 7 eyes (70%), a visual acuity of 1.0-0.7 was recorded in three eyes, an acuity of 0.4-0.1 also in three eyes and an acuity of 0.04 in one eye. The cause of failure in all instances was detachment of the retina. PPV is an obvious asset in the treatment of chronic uveitis associated with thick exudation into the vitreous body.

[Vitrectomy in retinal detachment caused by diabetic retinopathy].

We reviewed the surgical results obtained in 23 eyes that underwent vitrectomy for diabetic traction retinal detachment. Retinal reattachment was obtained in 75% of eyes, however the functional results were modest, owing to retinal changes related to diabetic retinopathy and/or longstanding macular detachment. Ambulatory vision was obtained in 60% of eyes. 8 eyes (40%) had final visual acuity of 1/20 or better. Four preoperative clinical findings were associated with a poor prognosis = absence of scatter retinal photocoagulation, dense vitreous hemorrhage, iris neovascularization and preoperative visual acuity reduced to "light perception". Iatrogenic retinal breaks were also associated with a poor prognosis.

Combined vitrectomy, cataract extraction, and posterior chamber intraocular lens implantation in diabetic patients.

Combined extracapsular cataract extraction, pars plana vitrectomy, and posterior chamber intraocular lens implantation was performed in six eyes with proliferative diabetic retinopathy. These eyes all had minimal iris vascular changes and were at reasonably low risk for developing intraoperative and postoperative complications. The surgery must be relatively brief and the endophotocoagulation accurate. Initial visual acuities ranged from light perception to 4/200. With an average follow-up of 9.7 months, final acuities ranged from 4/200 to 20/40.

[Posterior chamber lens implantation concurrent with vitrectomy for proliferative diabetic retinopathy].

Combined operation of cataract removal with posterior chamber intraocular lens implantation and pars plana vitrectomy were performed on 25 eyes in 22 patients with cataract concurrent with diabetic retinopathy. In 21 eyes, extracapsular cataract extraction followed by intraocular lens insertion, aiming at in-the-bag fixation, was performed, and in 4 eyes pars plana lensectomy with anterior capsule left and intraocular lens insertion between the iris and anterior capsule was carried out. Mean postoperative follow-up period was 14 months, ranging from 3 to 32 months. Visual acuity on the last examination was 0.5 or better in 2 eyes (8%), 0.1 or better in 12 eyes (48%), and worse than 0.05 in 9 eyes (36%). Major postoperative complications were fibrin reaction (20 eyes, 80%), pupillary deformation (19 eyes, 76%), pupil capture by intraocular lens (3 eyes, 12%), rhegmatogenous retinal detachment (1 eye, 4%), neovascular glaucoma (2 eyes, 8%), and recurrent vitreous hemorrhage (13 eyes, 52%). Intraocular pressure was well controlled in neovascular glaucoma cases. At the last examination ocular fundus was invisible due to vitreous hemorrhage in two eyes.

[Pars plana vitrectomy in double perforation of the eyeball].

Authors have presented treatment results of severe eye injuries with double perforation of the anterior and posterior wall of the eyeball. A seven-year experience in the treatment of 13 patients has been presented. Pars plana vitrectomy (PPV) is a relatively new, radical, beneficial and efficacious surgical method in the treatment of double eyeball perforations. Its performance depends directly on the local status of the injured eye and optimal time of performance is within 48 hours after the injury.

[Vitrectomy for non-diabetic vitreous hemorrhage].

45 cases (52 eyes) of non-diabetic vitreous hemorrhage, including 21 cases of Eales' disease, 20 cases of retinal venous obstruction, 4 cases of SMD etc. had visual acuities of 0.05 or less, except 1 eye of 0.4. After pars plana vitrectomy, some in combination with scleral encircling, vision in 62.7% of the eyes reached 0.1 or over, while 80.7% showed improvement. The points of note during operation, the proper timing of the surgery and complications were discussed.

[The indications for and sequence of vitrectomy and scleroplastic operations in posttraumatic retinal detachment and vitreous body pathology (1)].

The paper presents a clinical analysis of surgical treatment of 378 patients (426 operations) with posttraumatic retinal detachment. A broadened variant of a classification of traumatic retinal detachment signs in associated pathology of the retina and vitreous body is proposed. Recommendations are worked out concerning the approach of surgical treatment of traumatic detachment with determination of indications and the sequence of vitrectomy and scleroplastic operations. It is advisable to assess the effectiveness of surgical intervention in this pathology in more delayed terms.

Surgical treatment of postoperative dilated, nonreactive pupil in eyes after combined pars plana lensectomy and vitrectomy.

Synechiae between the iris and tissue posterior to the iris can cause a markedly dilated, nonreactive pupil that is cosmetically undesirable after combined pars plana lensectomy and vitrectomy for complicated forms of retinal detachment. The authors have used a combined limbal and pars plana approach to lyse the posterior synechiae, resulting in partial pupillary constriction. The surgical technique is described, and clinical results are illustrated.
