Handheld lasers can produce permanent retinal damage with visual sequelae if improperly used. Spectral domain optical coherence tomography demonstrates chronic disruption, primarily in the retinal pigment epithelium/photoreceptor region.
Endoscopy-assisted vitrectomy with removal of anterior proliferative vitreoretinopathy from the ciliary body is an effective treatment for chronic hypotony after previous retinal detachment repair in a minority of cases. The IOP improved in patients who tended to be younger and who had fewer previous intraocular surgeries. Further study is indicated to evaluate long-term outcomes and predictors of surgical success.
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.
