Relapsing polychondritis (RP) is a rare systemic autoimmune disease characterized by episodic inflammation of cartilaginous tissues throughout the body. It is distinguished by recurrent bouts of inflammation, which lead to the permanent destruction of the involved structures. It can be a life-threatening, debilitating, and frightening disease and is often difficult to diagnose in its early stages. Ocular manifestations have been reported to occur in up to 65% of cases and include proptosis, eyelid edema, extraocular muscles palsy, episcleritis, scleritis, conjunctivitis, corneal infiltrate, peripheral ulcerative keratitis, corneal thinning or perforation, iridocyclitis, cataract, retinopathy, exudative retinal detachment, and optic neuritis. Corticosteroids remain the mainstay of treatment for RP; however, other treatment modalities include nonsteroidal anti-inflammatory drugs, colchicine, dapsone, and immunomodulatory drugs. This article reviews the literature and summarizes the epidemiology, pathogenesis, clinical features, treatment, and prognosis of the systemic and ocular manifestations of RP.
Induced corneal astigmatism is a previously undescribed complication that can occur after DBSK. It is unclear whether the induced astigmatism in our patient was caused by the DBSK procedure alone or whether the patient had decompensated structural integrity from forme fruste keratoconus or blunt corneal trauma or both. The authors recommend that corneal topographic analysis be appropriately considered before DBSK for RCE and that corneal astigmatism be seen as a potential complication of the procedure.
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.
