[Time course of visual functions in patients with pigmentary retinal degeneration after surgical treatment with...

The effects of operations using alloplant biomaterial on the time course of visual functions were evaluated in patients with pigmented degeneration of the retina in various terms after surgery. 198 patients with terminal and subterminal stages of pigmented degeneration of the retina were operated on by inserting alloplant into the suprachoroidal space, after which they were observed for 1, 2, and 3-5 years. Visual acuity, kinetic and static visual fields were measured and computer perimetry was carried out. Analysis of the results indicates that the operation making use of alloplant leads to statistically significant improvement of visual fields and visual acuity and to stabilization of these functions during the periods of observations in patients with subterminal and terminal stages of pigmented degeneration of the retina. These data allow us to regard the operation with alloplant as one of the methods inhibiting the development of pigmented degeneration of the retina and in some cases improving the visual function.
