Observation on clinical effects of panretinal photocoagulation for ishchemic type of central retinal vein occlusion

[Objective] Observing and evaluating the clinical effects of panretinal photocoagulation with Argon laser for ishchemic type of central retinal vein occlusion.[Methods] According to the results of fundus fluores- cence angiography(FFA),panretinal photocoagulation with Argon laser were performed on 46 eyes (46 cases)of ishchemic type of central retinal vein occlusion.After photocoagulation, examination about fundus condition were carried out every 3 months, FFA was performed every two weeks. The vegular following up lasted for 6 months to 2 years.[Results] Laser photocoagulation was proved effective in 39 eyes (84.8%) with ishchemic type of central retinal vein occlusion. The visual acuity was improved in 7 eyes ( 15. 2%), no changes in 33 eyes (71.7%), decrease in 6 eyes (13.1%).[Conclusion] Panretinal photocoagulation with Argon laser is a safe and effective method to treat ishchemic type of central retinal vein occlusion.
