Abstract

Purpose: To find out if patients with proliferative vitreoretinopathy (PVR) due to complicated retinal detachment are at risk to acquire the same disease or other vision-threatening retinal abnormalities in the fellow eye. To furthermore assess in what time-period they appear and if subgroups of patients have special risks.

Methods: 100 consecutive PVR-patients were studied retrospectively. 21 patients with PVR graded lower than C3, traumatic PVR, diabetic retinopathy or congenital vitreoretinal diseases were excluded. Age, gender, best-corrected visual acuity at the first and last visit, refraction, ocular disease in both eyes and observation-time were recorded.

Results: After a mean follow-up of 8.5 years, 42 of 79 patients (53.4%) showed vision-threatening abnormalities in their fellow eyes: among them, 9 patients (11.4%) had PVR, 13 (16%) simple retinal detachments and 14 (17.3%) retinal breaks. Abnormalities in the fellow eye did not develop after a certain time following surgery of the primary eye; 71.4% appeared within 5 years. Aphakic and pseudophakic patients had retinal breaks significantly more often (p = 0.011) than phakic patients. Myopia did not increase the risk for any abnormality. Men developed retinal detachment (p = 0.037) and PVR (p = 0.025) significantly more often than women.

Conclusion: Patients with PVR have a greater than 50% risk of developing vision-threatening retinal abnormalities in their fellow eye. Because of this increased risk, these patients need regularly-scheduled long-term follow-up.

Summary Statement: Patients with PVR have a greater than 50% risk of developing vision-threatening retinal abnormalities in their fellow eye and a 37% risk to develop PVR from rhegmatogenous retinal detachment. More than two thirds of abnormalities in the fellow eye developed within five years of surgery of the primary eye.
