ABSTRACT
Objective To study the changes of corneal endothelium after silicone oil tamponade.Methods This trial involved 81 cases (81 eyes) who received vitrectomy with tamponade of silicone oil or vitrectomy and lensectomy with tamponade of silicone oil. The changes of corneal endothelium were observed before surgery and 1week, 1 month, 3 month, 6 month after surgery. Results The mean corneal endothelial cell densities was significantly decreased after surgery in all cases (P
ABSTRACT
Objective To observe the therapeutic effect of Argon laser photocoagulation on macular choroidal neovascularization. Methods 57 cases(58eyes)with macular choroidal neovascularization were treated with Argon laser photocoagulation,the visual acuity, the changing of macular choroidal neovascularization and macular hemorrhage before and after treatment were observed and compared with 34 cases(34eyes)with macular choroidal neovascularization who were treated with drugs.The average follow-up was 48(from2 to 84) months.Results The retinal hemorrhage decreased evidently in cases treated with laser coagulation.The hemorrhage absorb in therapeutic group is more evident than that in control group,There are statistically difference between the two groups(0.01＜P＜0.05).There are sig- nificantly difference between the two groups in increased visual acuity and choroidal neovascularization disappeared(P＜0.01).Couclu- sions Argon laser photocoagulation is effective on macular cloroidal neovasculurition.
