  • Abstract
  • Look Inside

We treated 65 eyes of 61 patients with typical central serous chorioretinopathy by means of red krypton laser. Laser beam was applied directly to the site of leakage of fluorescein and the surrounding areas. We normally used a relatively large spot size (200μm), low intensity (85mW) and longer dura-tion (200msec).

Typically, the visual acuity began to improve week after photocoagulation. The serous detachment in the macula disappeared after an average of 2.9 weeks. Full visual acuity was attained after onemonth.

When compared with argon, red krypton laser resulted in less damage to the sensory retina and in smaller objective scotoma that could be recorded in 17 eyes (55%).

Because of this feature, there was no patient who noticed subjective scotoma. From these findings, we think that the krypton laseris superior to argon in the treatment of central serous chorioretinopathy, particularly in cases with leakage points located in the perifoveal area.
