Pemphigus vulgaris is an uncommon but serious autoimmune disease that produces blisters of the skin and mucous membranes. Ocular findings are rare, but include conjunctivitis and marginal eyelid erosions. Conjunctival blisters and erosions related to this condition have not been previously reported in the literature. This diagnosis can be made through direct immunofluorescence tests performed on biopsy samples of affected tissue. Unless the condition is properly diagnosed and treated, it has a high mortality.
Ciliary body melanocytoma is a rare benign pigmented tumor that may present extension to the anterior chamber. Differential diagnosis mainly includes ciliary body melanoma, which carries a different prognosis and treatment.
SiFO may be useful as an intraoperative tool, although its main drawback is a more difficult injection and aspiration compared to PFO. It has been well tolerated as a short-term vitreous substitute, but further clinical studies are needed.
Primary localized conjunctival amyloidosis is a rare disease. Diagnosis consists of biopsy in order to detect amyloid material in the conjunctival tissue together with a systemic evaluation in order to rule out the presence of primary systemic amyloidosis.
The presentation of SO in a vitrectomized patient after severe blunt trauma with extended intra-ocular tamponade with PFCL could support the hypothesis that chronic inflammation caused by PFCL could have contributed to the development of SO. Nevertheless, there are other possible causal factors such as the trauma, the vitrectomy itself or the choroidal detachment with possible uveal incarceration at wound sites.
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.
