ObjectivesTo evaluate the therapeutic effect of argon laser photocoagulation combined with intravitreous injection of triamcinolone acetonide (TA) on ischemic central retinal vein occlusion (CRVO).MethodsArgon laser photocoagulation combined with intravitreous injection of TA was performed on 17 patients (17 eyes) with CRVO between December 2003 and July 2004.ResultsDuring the follow-up of 4-10 months, the visual acuity improved in 16 patients, including alleviated or even disappeared cystoid macular edema (CME) in 5, and recurred macular edema in 5 with decreased visual acuity after 3 months. Six patients had increased ocular pressure after intra-ocular injection which alleviated after treated suitably. No neovascularization in angle or secondary neovascular glaucoma was found.ConclusionArgon laser photocoagulation combined with intravitreous injection of TA may improve the visual acuity and reduce complications in ischemic CRVO, though macular edema may recur in some cases.
