Retinal detachment and miotic therapy

Abstract

We studied a series of 34 eyes in 31 patients in whom retinal detachment occurred during miotic therapy. In 14 eyes, the duration of miotic use before the development of detachment was two months or less. Most detachments occurred in detachment-prone eyes either by virtue of myopia (62%), aphakia (24%), ipsilateral lattice degeneration (38%) or retinal pathology, in the fellow eye (50%). Virtually all detachments were rhegmatogenous. Distributions of retinal breaks are similar to the corresponding profiles in detached eyes not receiving miotics. The observed phenomena may be accounted for mechanistically, either with or without the role of miotics, so a specific causal role cannot be assigned to any given miotic in any given case. However, our data suggest that detachment-prone eyes may be at increased risk with miotic use, and thus demand careful retinal evaluation and prophylaxis when ominous peripheral symptoms are present.
