Last Month’s Blink
“Evanescent Cataract,” or Gas-Induced Lenticular Opacification

A 45-year-old man presented with complaints of diminishing vision in his right eye for 1 week. Fundus examination revealed a total retinal detachment with hand motion vision in that eye. The left eye was normal. He underwent pars plana vitrectomy with scleral buckle and a gas tamponade with sulfur hexachloride. On the first day postoperatively, the posterior segment examination revealed an attached retina with a 90% gas-filled eye. In addition, we observed a new-onset posterior subcapsular cataract, which had a ferning pattern (Fig. 1).
On subsequent follow-up appointments over 7 days, we saw the gradual disappearance of the cataract (Fig. 2) without any intervention, which is why we call it “evanescent cataract.” The reason for the disappearance is unclear; we attribute it mainly to gas-induced oxidative stress—as the gas was absorbed the cataract vanished.
