Abstract

The topography of functional activity of the macula zone before and 3, 6 and 12 months after laser coagulation of the retina of 34 fellow eyes with peripheral vitreoretinal dystrophies (PVRD) was studied in patients with rhegmatogenous retinal detachment and in patients with PVRD on both eyes. The multifocal ERG (mfERG) data showed a decrease in functional activity of the central retina when PVRD. In the eyes with PVRD progression stronger reduction of mfERG was found before and after the laser coagulation than in the eyes without PVRD progression, especially in the fovea, perifoveal and middle periphery zones. According to the results of mfERG, the laser coagulation at the retinal periphery associated largely with the reduction in functional activity of cone photoreceptors than cone bipolar cells.
