New treatments of premacular hemorrhages - about 5 cases

To evaluate functional results and evolution of premacular hemorrhages treated with Nd Yag laser. 5 patients presenting a macular hemorrhage were treated with Nd Yag laser. The cause was ruptured macroaneurysm in 2 cases, diabetic retinopathy in 2 cases, Valsalva manoeuvre in one case. Minimum number of impacts and minimal power are underwent to permit through a hyaloidotomy to the blood to flow out in the vitreous cavity. Surveillance comported visual acuity measurement and ophthalmoscopy. The follow up is 4 months. Initial visual acuity was limited to light perception. Ophthalmoscopy showed in all cases premacular hemorrhage of great size: [5 at 7 papillary diameters] and hemorrhage's etiology in 4 cases. Visual acuity improvement was noted in 4 cases with mean visual acuity of 5/10 after treatment [4/10 at 7/10]. Treatment of premacular hemorrhages with laser Nd Yag have the advantage to permit rapid resolution of hemorrhage and to restore visual acuity in young patients in activity. premacular hemorrages treatment with Nd Yag laser is a non invasive technique efficient and safe

[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
