Significant and persistent IOP spikes requiring surgical intervention following SLT are extremely rare, with only 1 other case series of 4 patients (all with heavily pigmented angles) reported in the literature. Exfoliation patients, and likely all patients with heavily pigmented angles, should be considered at higher risk for developing this complication. Corneal endothelial failure is similarly rare. Nine cases have been reported in the literature, none requiring corneal transplantation. Further clinical attention and research is needed to help elucidate what factors (both pressure-dependent and pressure-independent) may predispose patients to corneal changes following SLT.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
