Comparative study of clinical factors that predispose patients to proliferative vitreoretinopathy in aphakia.
To clarify the risk factors of proliferative vitreoretinopathy (PVR) in aphakia, the clinical features of 25 aphakic eyes with PVR were statistically analyzed and compared with a control group of 157 aphakic eyes with non-PVR rhegmatogenous retinal detachment. The statistically significant (P less than 0.05) factors that predisposed patients to PVR in aphakia were as follows: a history of vitreous loss on cataract surgery, retinal detachment developing within 3 months after cataract extraction, duration of retinal detachment longer than 3 months, break larger than three disc diameters, and choroidal detachment. Vitreous loss is believed to play the most important role in the development of PVR in aphakia.
