A Clinical Study on the Fellow Eyes in Unilateral Retinal Detahment

ABSTRACT

The vitreous and fundus changes in the fellow eyes of 121 patients with unilateral retinal detachment were evaluated ophthalmoscopically. Fourteen cases with traumatic retinald etachment were included in this study. We studied the relationship between the posterior vitreous detachment, lattice degeneration, retinal holes, myopia and retinal detachment to be of any help in prevention of progression of retinal detachment. Retinal breaks were found in 11.6% and lattice degeneration in 21.5% of fellow eyes. The frequency of retinal breaks and lattice degeneration in fellow eyes were greater than that of retinal breaks and lattice degeneration in normal eyes. Retinal breaks and lattice degeneration were found most frequently in the superior temporal quadrant followed by the inferior temporal quadrant. Posterior vitreous detachment(PVD) was found in 33.9% of fellow eyes. Of the 41 eyes with PVD, 22 eyes had retinal breaks and lattice degeneration and 19 eyes had no retinal breaks and lattice degeneration. The proportion of myopia was 54.5% and that of high myopia over -8.0D was 16.5%. The proportion of myopia and high myopia were higher in the fellow eye of patients with unilateral retinal detachment than in general population. In myopic eyes, the incidence of retinal holes, lattice degeneration, and PVD were greater than that of retinal tear.
