Argon laser photocoagulation for chronic clinically significant cystoid macular edema

We report the therapeutic outcome of 14 eyes of 11 patients with chronic clinically significant pseudophakic cystoid macular edema refractory to medical management who underwent argon laser photocoagulation of the perifoveal area. Inclusion criteria included chronic cystoid macular edema of more than six months duration of decreased visual acuity (20/100 or less), positive fluorescein angiogram and contact lens examination, pseudophakos with posterior chamber intraocular lens and intact posterior capsule, normal fasting blood sugar, failed medical treatment and minimal follow up of six months. Fifty per cent of the eyes improved after laser treatment (p = .0345, relative to unchanged plus worsened cases). Further prospective, randomized, clinical trials are recommended to define the effectiveness of this treatment protocol.
