[Effectiveness of laser therapy in retinal vein thrombosis]

The authors compared the results of treatment in a group of patients (1st group--20 persons) with a retinal vein thrombosis with a second group (24 persons--25 eyes) treated pharmacologically with a simultaneous laser photocoagulation performed by argon and crypton lasers. Improvement of the visual acuity in late observations was established in 40 per cent of eyes of the 1st group and in 64 per cent of the 2d group; worsening was observed in 55 per cent of eyes of the 1st group and in 8 per cent of the 2d group. The authors consider that an early applied laser photocoagulation is beneficial in the treatment of the retinal vein thrombosis and besides that pharmacological treatment coupled with laser photocoagulation gives much better results than the pharmacotherapy alone.
