Review of laser treatment at Keio University Eye Clinic.

Between 1978 and 1992, 5310 eyes in 4317 cases were treated by laser photocoagulation at our clinic. Argon, krypton and dye lasers with slit lamp microscope were used 7556 times for 4446 eyes. Main indications included diabetic retinopathy, retinal vein occlusion, retinal break and glaucoma. For treatment of these diseases, argon blue-green and green laser were chosen in majority of cases. Macular diseases were treated most frequently by krypton laser. Endophotocoagulation by argon laser during vitreous surgery was performed in 399 eyes mainly with diabetic retinopathy, retinal detachment and retinal vein occlusion for 7 years. Treatment by Nd: YAG laser was done in 465 eyes for 5 years and more than 90% of cases were performed capsulotomy for after-cataract. Numbers of cases treated by any kinds of laser is increasing with the years.
