[Vitrectomy results in retinal vein occasion]

Retinal vein occlusion results in decrease of visual acuity secondary to complications such as intravitreal hemorrhage due to retinal neovascularisation, neovascular glaucoma and retinal detachment. The purpose of our study is to discuss the surgical indications, the results and the post operative complications after vitrectomy for intravitreal hemorrhage or retinal detachment due to retinal vein occlusion. 75% of our patients underwent vitrectomy for retinal vein occlusion with retinal neovascularisation and intravitreal hemorrhage. A three port pars plana vitrectomy was performed, and if needed peeling of fibrovascular membrane, endophotocoagulation, scleral buckling and internal tamponnement. Improvement in visual acuity was noted in 80% of the patients. Cataract was the main postoperative complication : in 80% of cases. Final prognosis was determined by the macula state

[Indications and results of vitrectomy in terson syndrome]

Terson syndrome or vitreal hemorrhage associated with subdural hemorrhage is a rare condition. The goal of our work through a retrospective series of 3 cases [4 eyes] is to study clinical characteristics as well as adequate moment of surgery. All our patients had unilateral or bilateral visual impairement secondary to cerebral lesion. Ophtalmologic exam showed an intravitreal hemorrhage. Two of our patients were operated by vitrectomy, the third case had a spontaneous resorption of intravitreal hemorrhage and no surgery was performed. Functional prognosis depends on neuro-ophtalmologic sequellas. Ophtalmic exam is essential in cerebral hemorrhage. For intravitreal hemorrhage spontaneous resorption is frequent and vitrectomy must be delayed
