Pneumatic retinopexy perfluoroethane (C2F6) in the treatment of rhegmatogenous retinal detachment.

Due to differences in expansile properties and duration, perfluorethane gas may offer advantages over other gases presently used for pneumatic retinopexy. Seventeen eyes with retinal detachments with single retinal breaks or groups of breaks no greater than 1 clock hour in extent were prospectively treated with perfluoroethane gas injection and retinocryopexy and followed up for a minimum of 6 months. Twelve eyes (71%) were attached with one procedure, and five eyes (29%) were attached with two or three procedures. Post-operative proliferative vitreoretinopathy occurred in two eyes (12%), new or missed breaks in three eyes (18%), and premacular fibroplasia in one (6%) eye. No eyes had an apparent progression of cataracts. Seven (88%) of eight eyes with preoperative macular detachments had improved visual acuity after surgery. All nine eyes (100%) with preoperative macular attachment had the same or improved visual acuity after surgery. The efficacy of perfluoroethane appears similar to that of other perfluorocarbon gases.

Selection of surgical technique for retinal detachment with coloboma of the choroid.

Four eyes with rhegmatogenous retinal detachment and coloboma of the choroid were managed by conventional scleral buckling (one eye); scleral buckling combined with lensectomy, vitrectomy, and fluid-air exchange (two eyes); and vitrectomy, silicone oil injection without scleral buckling (one eye). Retinal break was seen within the coloboma in two eyes, at the periphery in one eye, and, both in the coloboma and periphery in one eye. At a follow-up of 15 months, the retina was found attached in all the patients. The success of these surgical procedures could be attributed to careful preoperative/intraoperative fundus examination and individualised surgical planning.

[Evaluation of the surgical treatment of retinal detachment in children. Personal data].

Twenty nine children aged 8-18 years with retinal detachment were treated in the period 1980-1987. The cause of detachment was in 27 cases injury and in 2 cases rupture of a congenital retinal cyst. In the majority of cases the detachment was connected with a dialysis at the ora serrata and comprised two quadrants of the fundus' periphery. The operation in 25 children consisted on implantation of a silicone sponge. A hard silicone implant situated intrasclerally with a band round the globe was used in 3 persons. A cerclage of the eye ball with a silicone sponge was performed only in one child. In 25 children the retina reattached after operation.

[Surgery treatment of retinal detachment with Marfan syndrome].

PURPOSE: To detect the reattachment rate and visual function outcome of Pars Plana Lensectomy, vitrectomy and scleral encircling (PPL + PPV + SE) to treat retinal detachment (RD) with Marfan syndrome. METHODS: A retrospective study of 11 cases of 14 eyes with Marfan syndrome who submitted to PPL + PPV + SE. RESULTS: All the cases were followed up for four - 46 months (means 31.2 months). Retinal reattachment rate was 85.7%, visual acuity were 0.3 or better in eight cases. CONCLUSION: PPL + PPV + SE is a safe and effective treatment for retinal detachment with Marfan syndrome.

[Long-term results of successful surgical treatment of retinal detachment by vitrectomy and silicone oil injection. Effect of removal of the tamponade on further complications].

We present, with a minimal follow up of six months, the results of 118 silicone oil removals following successful treatment of retinal detachment by pars plana vitrectomy and silicone oil injection. A recurrent retinal detachment occurred in 8.5% of cases, 13% of the 61 phakic eyes at the time of silicone oil removal maintained a clear lens, 29.6% of the eyes had a raised intraocular pressure and 6.8% had a keratopathy. The visual acuity improved in 72.8% of eyes after silicone oil removal. The main reasons for a late decrease in visual acuity were recurrence of the detachment, hypertonia, chronic hypotonia and keratopathy. All the eyes with late complications after silicone oil removal had a clinically significant droplet dispersion in the anterior chamber. Only complete and early silicone oil removal seems to decrease the complication rate.

Changing concepts of failures after retinal detachment surgery.

One thousand eighty-eight consecutive operations for retinal detachment were analyzed to determine the influence of current methods of examination and treatment on failures following surgery. The majority of failures were produced by preretinal membranes formation (33%) and massive preretinal retraction (27%). Other causes of failure included undetected retinal breaks (13%), inadequate scleral buckel (10%), new retinal breaks (8%), inadequate chorioretinal reaction (7%), and iatrogenic retinal breaks (2%). Primary operations yielded an initial cure rate of 76%. Successful reoperations raised the final cure rate to 89%. Reoperations were associated more frequently with preretinal membrane formation and chance of recognition and management of preretinal membrane formation. Except for new retinal tears and massive preretinal retraction, surgical failures can be avoided by improved utilization of current examination and operative techniques.

Surgical treatment of retinal detachment in the choroidal colobomas.

Seven eyes from seven patients with retinal detachment and choroidal coloboma (with or without optic disc involvement) were treated. The retinal break was always inside the colobomatous area, except in the cases with evidence of peripheral retinal breaks. In order to produce reattachment of the retina, vitrectomy procedures with removal of posterior hyaloid were used. Drainage of subretinal fluid was performed through the break in the area of the coloboma, with simultaneous fluid-air exchange. Previously undetected retinal breaks were identified by inspecting for the presence of schlieren in the colobomatous area during fluid-air exchange. A peripheral scleral buckle was then applied. Argon laser endophotocoagulation was performed, but when the coloboma involved the optic disc, red krypton endophotocoagulation was used. Retinal reattachment was achieved in all cases.

Randomized clinical trial of intraocular silicone vs. gas in the management of complicated retinal detachment and vitreous hemorrhage.

We performed a prospective randomized clinical study to compare intravitreal silicone oil vs. gas (20% C3F8 or 30% C4F8) in the management of complicated retinal detachments and vitreous hemorrhage. Despite similar anatomic and visual results, the gas-treated group had significantly more instances of vitreous hemorrhage, late elevated intraocular pressure, and localized retinal detachment as postoperative complications than those receiving oil injections (P less than .05). Silicone oil injections containing less than 3.0 ml contributed significantly to postoperative detachments (P less than .05).

[Scleral pocket on the posterior pole and treatment of retinal detachment induced by a macular hole].

Microsurgery has enabled modifications in initial surgical technique for lamellar scleral pocket and patch pocket on the posterior pole in the treatment of retinal detachments associated with macular holes occurring in high myopic eyes. The new microsurgical technique, employing suitable surgical instruments, was employed in 17 retinal detachments associated with macular holes. Surgical success was achieved in 14 cases (82 p. cent). The advantages and the disadvantages of lamellar scleral pocket and patch pocket on the posterior pole are discussed.

[Value of silicone sponge in retinal detachment surgery].

Lincoff's development of silicone sponge and substitution cryosurgery for diathermy in the mid-1960s, was the beginning of the minimized surgery for retinal detachment, limited to the surgery of the breaks. The aim of this paper is to present our experiences with these kinds of operations, with special attention to the complications causing the necessity of removing the sponge. Our studies concerned the patients who underwent retinal detachment surgery, in the Ophthalmological Clinic in Cracow in the years 1983-1992, using scleral buckling procedures with silicone sponge. In 152 cases circumferential and in 36 radial local scleral buckling procedures were performed; in 30 cases local buckling was added to encirclement with silicone band. The complications, attributed to the sponge, were observed in 9.7% of cases. Anterior segment inflammatory reactions, often sterile were found in 15 eyes, in 7 of them it was necessary to remove the sponge. In 13 eyes the sponge was removed on account of its extrusion. In none of the cases removal of the sponge influenced the retinal attachment. Our studies confirmed, that silicone sponge is a very good material for scleral buckling procedures.

The incidence of macular pucker after retinal detachment surgery.

In a study of 63 cases of macular pucker among 857 patients who underwent retinal detachment repair, we isolated several statistically significant risk factors: preoperative vision of less than 6/15 (20/50); preoperative presence of rolled edges, starfolds, or equatorial ridges; re-operations; choroidal hemorrhage; and age past 30 years. We were unable to confirm the risk associated with vitreous loss, vitreous hemorrhage, and degeneration. Results suggested that macular pucker after detachment surgery is produced by a membrane similar in origin to those causing other forms of periretinal proliferation.

[Vitreoretinal surgery in complicated retinal detachment in children and adolescents].

BACKGROUND: The purpose of this study was to evaluate anatomical and functional results of vitreoretinal silicone oil surgery for complicated retinal detachments due to trauma and myopia in children and juveniles. METHODS: We retrospectively reviewed the records of children and juveniles up to 17 years of age who had undergone vitreoretinal surgery with silicone oil instillation for the above causes between 1990 and 1997. A total of 30 eyes of 29 patients were operated on, 24 because of trauma and the remaining 6 because of retinal detachment in high myopia. There was a mean postoperative follow-up period of 1.7 years. Silicone oil could be removed from 18 of the 30 eyes after a mean of 4.7 months. The median number of vitrectomies performed per eye was two (range one to five). RESULTS: In 21 of 30 eyes (70%) the retina could be reattached after one or more surgeries. Silicone oil was removed from 16 of these 21 eyes (53%) which was defined as anatomical success. Visual acuity increased (14 eyes, 48.3%) or remained unchanged (9 eyes, 31%) in 23 of 29 eyes (79.3%). Visual acuity decreased in 6 of 29 eyes (20.7%) despite surgery. Two eyes (6.7%) had to be enucleated due to bulbar phthisis. Seventeen eyes reached a postoperative visual acuity of at least counting fingers. In one child functional tests could not be performed due to young age. CONCLUSION: Vitreoretinal surgery with silicone oil endotamponade has become a standard procedure in treating complicated retinal pathologies in children and juveniles. In very young patients it is thought that silicone oil instillation has advantages over gas endotamponade since it is very difficult for children to keep the proper face-down positioning after the procedure. The retinal reattachment rate is encouraging. In the majority of cases visual acuity greater than or equal to counting fingers and thus orienting vision was reached postoperatively. In few cases even reading vision was regained.

[Prevention of retinal detachment and treatment of retinoschisis].

The necessity for prophylactic treatment for degenerative disease in the peripheral retina cannot be evaluated merely on the basis of the ophthalmoscopic findings. Factors such as the patient's history, refraction, the status of the vitreous, and prospective future cataract extraction all have a major impact on the risk of developing retinal detachment. The latter condition can be classified in to three groups: (1) low risk (patients with no history of retinal detachment, intraocular surgery or posterior vitreous detachment, myopia less than three diopters): treatment of atrophic holes and lattice degeneration is not justified, treatment of flap tears according to the circumstances; (2) medium risk (patients with no history of retinal or posterior vitreous detachment; however, myopia of more than three diopters and/or aphakia): the treatment of lattice degeneration is not justified; treatment of breaks according to the circumstances; (3) high risk: (patients with symptoms of posterior vitreous detachment): the treatment of lattice degeneration and atrophic holes is not justified: treatment of tears is necessary; fellow eyes: the treatment of retinal breaks is necessary; treatment of lattice degeneration seems advisable in cases with bilateral symmetric findings or prior to cataract extraction. Treatment of senile retinoschisis is only justified in cases with large and centrally located holes in the outer wall or in the presence of symptomatic schisis detachment.

Surgical treatment of retinal detachments complicated by proliferative vitreoretinopathy.

During the last four years we treated 82 consecutive patients (83 eyes) with retinal detachments complicated by proliferative vitreoretinopathy. We used pars plana vitrectomy combined with a broad scleral buckle, cryotherapy to the retinal breaks, and a temporary intraocular gas bubble. The retina was successfully reattached in 55 eyes (66%). Our success rate improved from five of 12 eyes (42%) in 1980 to 25 of 31 eyes (81%) in 1983. We believe that a better understanding of the disease process and the use of a combination of surgical techniques were the main factors accounting for our improved results during the last years of this series.

Retinal detachments and topical ocular miotics.

There is increasing suspicion that topical ocular miotic therapy in selected persons may precipitate retinal detachments. This is a rare event and probably does not occur in patients free of retinal pathology. Data supporting a possible cause and effect relationship, obtained from the National Registry of Drug-Induced Ocular Side Effects, a survey of the Retina Society, medicolegal decisions, and a review of the literature, is presented.

Retinal detachment with severe proliferative vitreoretinopathy in Terson syndrome.

BACKGROUND: In several reports, early vitrectomy has been proposed for eyes with vitreous hemorrhage due to Terson syndrome as a means to hasten visual recovery. But the development of nuclear sclerosis and the neurologic problems arising from this disease encourage surgeons to wait for spontaneous resorption, especially with young patients. Although the formation of epiretinal membranes has been described, to the authors' knowledge retinal detachment with proliferative vitreoretinopathy in Terson syndrome never has been observed. METHODS: The authors report five eyes from four patients with Terson syndrome due to spontaneous aneurysm rupture, in whom retinal detachment with proliferative vitreoretinopathy developed. RESULTS: The early onset and the severe clinical course of proliferative vitreoretinopathy in these eyes showed parallels to traumatic proliferative vitreoretinopathy. The retina in all eyes could be reattached. CONCLUSION: The authors point out the necessity for accurate and close follow-up and early, extensive surgical treatment in Terson syndrome, especially in patients with a reduced general state of health.
