Abstract

Purpose: To evaluate the rate of increase in nuclear sclerosis and posterior subcapsular cataracts in eyes as a function of patient age and use of intravitreal gas at the time of vitrectomy. Methods: Nuclear sclerotic cataracts and posterior subcapsular cataracts were graded on a scale of 0 to 4. 0 in 301 consecutive eyes prior and subsequent to vitrectomy for macular holes, epiretinal membranes, or vitreomacular traction syndrome. Linear regression analysis was performed to compare the rate of change in cataract score. Results: Nuclear sclerotic cataracts showed minimal increase in patients younger than 50 years of age following vitrectomy (.13 grades per year). Nuclear sclerotic cataracts increased at a rate of .7 to .9 grades per year (mean, .812) in patients from age 50 to 60, 60 to 70, 70 to 80, and 80+ years, even though the baseline nuclear sclerosis scores were progressively greater for each decade. The increase in nuclear sclerotic cataracts in patients younger than 50 years was significantly less (P
