We compared the therapeutic effect of blue-green argon and red krypton lasers in simple and proliferative diabetic retinopathy.

In 18 patients with similar degree of diabetic retinopathy in kind and intensity, one eye was treat-ed with argon and the other with krypton. The therapeutic effect was similar for both modalities when judged from fundus findings and visual acuity during the postphotocoagulation period. As a no-table difference, significantly less intense coagula-tion effect was obtained while using krypton than argon.

In another series of 9 eyes with cataract or vitre-ous hemorrhage treated with argon and krypton in different sessions, a lesser power output level was required to produce coagulation burns when using krypton than argon.

These findings indicate that red krypton laser results in similar therapeutic effects as argon when applied to diabetic retinopathy, whether simple or proliferative. Krypton appears to be more indicated in eyes with advanced cataract or opaque vitreous.
