Most everyone’s eyes will eventually go through posterior vitreous detachment (PVD), typically after age 50.1 During the course of PVD, patients are at increased risk of retinal tears and, according to a new study, myopia patients who’ve already experienced a retinal tear are at an increased risk of subsequent tears.2

The researchers looked at 176 eyes that experienced one or more retinal tears associated with PVD, and followed them for a minimum of one year. The investigators then divided them into two groups, one that presented with tears at the initial exam only (154 eyes) and a second group (22 eyes) that experienced additional tears following the initial exam.2

From the first group, 59.1% of the eyes were myopic, whereas 86.4% of the second group were. Of those, the researchers noted, 81.8% occurred within a 120-day period following the diagnosis of the original tear. The authors advise that patients be followed for at least four months after the initial symptoms, particularly for the higher-risk myopia patients.2
