Laser treatment of diffuse retinal pigment epitheliopathy.

The Authors report laser treatment of 18 eyes (14 patients) with a variant of central serous chorioretinopathy associated with widespread decompensation of the retinal pigment epithelium (RPE) in the macula, diffuse retinal pigment epitheliopathy (DRPE). All eighteen eyes with DRPE were treated with Krypton red laser photocoagulation in a grid pattern to leaking RPE in areas of neurosensory retinal detachment. All eyes showed anatomic improvement with resolution of the serous macular detachment and lipid exudation. The visual acuity was stabilized in 15 eyes (83%) at 6 months' follow-up, but only 3 eyes (17%) demonstrated improved visual acuity in the same time interval. At eighteen months, 2 of 15 eyes (13%) retained improved visual acuity, 11 eyes (74%) remained unchanged, and 2 eyes (13%) had visual loss. In this series of patients with DRPE, grid laser photocoagulation treatment was uniformly successful in producing an anatomic improvement in the exudative manifestations of the macula and in preventing or slowing progression of vision loss.
