Outcome of Vitrectomy on Vitreoretinal Pathologies due to Branch Retinal Vein Occlusion

32 eyes with vitroretinal pathologies caused by branch retinal vein occlusion (BRVO) under went pars plana vitrectomy. Visual acuity was restored postoperatively in 28 of 32 eyes (87.5%). Visual acuity was restored in 19 of 19 eyes (100%) with vitreous opacity only, in 5 of 6 eyes (83.3%) with fibrous proliferation and in 4 of 7 eyes (57.1%) with retinal detachment. Regarding final visual acuity. 78.1% showed 0.1 or better, and 43.8% showed 0.5 or better Among the complications. surgically induced retinal detachment showed the worst prognosis.

The Effect of beta-bocker on Postural Change of IOP

The intraocular pressures(IOP) were measured in both eyes of 30 healthy volunteers in sitting, supine, and 30 degrees head down positions One eye was pretreated with 1% carteolol or placebo(Tears naturale)applied in a masked, randomised fashion, while the other served as control. Although IOP changes in response to carteolol and to postural changes were significant(P<0.01), carteolol did not significantly alter relative changes in IOP from positional changes This results suggests that the overall pressure lowering effect may offer some protection to patients with glaucoma.
