Long-term visual outcome in Terson syndrome.

Abstract

The presentation and long-term visual outcome in 30 eyes with Terson syndrome is evaluated. In 25 of 30 eyes (83%), visual acuity of 20/50 or better was attained. This occurred in 12 of 16 eyes (75%) managed by observation alone and 12 of 14 eyes (86%) treated by pars plana vitrectomy. The most common long-term sequelae in all eyes studied was the formation of an epiretinal membrane. These occurred in 14 of 18 eyes (78%) followed for 3 or more years but accounted for significant visual loss in only 2 eyes. There was no difference in final visual outcome between those patients undergoing vitrectomy and those managed conservatively. However, visual recovery was more rapid in eyes undergoing vitrectomy despite the fact that vitrectomy was reserved for eyes with more dense vitreous hemorrhage.
