We suggest that the persistence of Cloquet's canal may permit fluid leakage into the proximal vitreous in cases of congenital optic nerve head pits. Tangential vitreal traction may promote the opening of a fistula at the optic pit and additionally thrust vitreal fluid into the pit and retinal space inducing the formation of schisis spaces, foveolar-schisis and underlying sensory serous detachment. We question whether a reduction in vitreous volume, induced by initial administration of anti-glaucoma medications, may contribute to the development and/or recurrence of central serous choroidopathy in predisposed individuals.
Peripapillary retinoschisis with an underlying serous detachment may develop in subjects with advanced glaucoma. Although the occurrence of the findings in this case may be unrelated to glaucomatous optic neuropathy, the likelihood that a pathogenic mechanism linked to advanced glaucoma may be responsible for the development of peripapillary schisis and serous detachment should alternatively be taken into consideration. This case documents its spontaneous resolution without intervention.
: Anterior nongranulomatous/granulomatous and posterior uveitis should be considered clinical manifestations of poststreptococcal syndrome in patients with a clinical history and/or serological evidence indicating possible past streptococcal infection. A variation of host-genetic-predisposed immune response, the patient's human leukocyte antigen haplotype, pathogen virulence, and/or deposition location of immune circulating complexes may give rise to the diverse spectrum of clinical ocular sequelae in poststreptococcal syndrome. Poststreptococcal uveitis may comprise a similar immunologic pathogenesis to that of acute rheumatic fever, acute glomerulonephritis, and other autoimmune diseases.
HRT and GDx-VCC indicators of RNFL thickness appear to be significantly reduced in HIV-positive subjects without retinopathy or optic nerve disease using antiretroviral medication, suggesting RNFL loss occurs in this population of HIV-positive patients. The lack of correlation between CD4 counts, viral load, number of antiretroviral medications used, or years from diagnosis of HIV and RNFL thinning, suggests that possibly other factors associated with HIV infection may contribute to the apparent RNFL thickness loss.
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.
