ABSTRACT
PURPOSE: To report the surgical success of vitrectomy with silicone oil tamponade in the treatment of retinal detachment associated with giant retinal tears due to various factors. METHODS: We retrospectively evaluated 21 eyes of 21 patients with retinal tears 90 degrees or greater that underwent vitrectomy, with injection of perfluorocarbon liquids and silicone oil tamponade. Eight eyes (38.1%) had previous ocular surgery (4 aphakia-pseudophakia, 4 pars plana vitrectomy), 4 eyes (19.0%) had a history of trauma (blunt injuries in 2 and penetrating injury in 2), 3 (14.3%) had high myopia. Six eyes (28.6%) had no known condition predisposing to development of giant retinal tear. RESULTS: Retinal attachment was obtained in 17 (80.5%) of 21 eyes, with a mean follow-up of 12.5 months. Visual acuity improved in 15 eyes (71.4%). CONCLUSIONS: Pars plana vitrectomy with silicone oil tamponade proved highly effective in giant retinal tears in terms of anatomical and functional results.

PURPOSE: To verify the functional and anatomical results of retinal detachments related to choroidal coloboma. METHODS: Seven eyes with retinal detachment secondary to retinal breaks at the margin of or within a choroidal coloboma were analysed retrospectively. RESULTS: Scleral buckling was performed in five of the seven eyes; two needed additional pars plana vitrectomy (PPV) with internal tamponade using silicone oil to reattach the retina. In two eyes PPV with internal tamponade using silicone oil or gas was used as a primary procedure. All seven eyes were reattached. Five eyes (71.4%) showed improvement or had visual acuity of 20/400 or better after surgery, but two remained unchanged. CONCLUSIONS: Retinal detachment secondary to choroidal coloboma can be treated successfully by scleral buckling or PPV with internal tamponade.

PURPOSE: To investigate the relationship between posterior vitreous detachment (PVD) and age-related macular degeneration (AMD). METHODS: The condition of the vitreous was examined by slit-lamp funduscopy and ultrasonography in 93 eyes of 50 patients with AMD (exudative or dry) and 100 eyes of 50 controls. RESULTS: There was complete PVD in 31 of the 93 eyes (33.3%) of 50 patients with AMD and the posterior vitreous was attached in 62 of these eyes (66.6%). In the control group, in 50 eyes (50%) of 50 subjects there was posterior vitreous detachment. The prevalence of PVD in eyes with macular degeneration was significantly lower (P < .05). There was no statistically significant difference between the exudative and the nonexudative groups in respect to PVD. CONCLUSIONS: PVD may have a protective role against the development of AMD. Chronic vitreomacular traction and/or continuous exposure to free radicals and cytokines may possibly be one of the causes of AMD in eyes with attached vitreous.
