..The purpose of this study was to investigate the repeatability of retinal oximetry using slit-lamp adapted ultrahigh-resolution optical coherence tomography (SL-UHR-OCT)...

..Histopathologic and molecular analysis revealed a low-grade B-cell lymphoma. Further evaluation showed no evidence of systemic disease. Primary dural lymphomas are a distinct entity that may mimic meningioma and cause vision loss...

..The authors described the system configuration, build-up, and test results of a small sample of human subjects. The comparison with a commercially available device was also included...

..Delays in diagnosis are common because of the frequent lack of typical chorioretinitis or vitreous inflammation. Adjacent macular involvement strongly influences visual outcome...

..Despite aggressive chemotherapy, the patient died within 6 months of presentation. This is the first report of an AT/RT presenting as an isolated third cranial nerve palsy caused by tumor arising from within the nerve...

..The longer a-wave latency in RP patients suggests that the rods and cones are altered over a significant area of the retina...

..Neuroimaging studies were unremarkable. We discuss the potential causes of our patient's visual symptoms and speculate and hypothesize that it may represent an atypical manifestation of migraine, perhaps related to a channelopathy...

..Allergic fungal sinusitis (AFS) is thought to represent an immunologic response to exposure to dematiaceous fungi. These fungi are known to cause disease more frequently in hot and humid climates and seasons...

..The blood flow velocities in the temporal conjunctival microvasculature were 0.86±0.08 (mean±SD, mm/s) for the bare eye and 0.99±0.11 mm/s with contact lens wear. It is feasible to use RFI for imaging the conjunctival vasculature...

..The results for 3 normal eyes and 3 eyes with retinal degeneration are analyzed, showing registration errors of 1.5±0.3 and 2.0±0.8 pixels respectively...

..The current case demonstrates the importance of including toxoplasmosis in the differential diagnosis of unilateral anterior optic neuropathy, even if a focal inflammatory mass is not apparent...

..Recent evidence for a role of antibody to aquaporin-4 in the pathogenesis of NMO has led to the use of rituximab, a monoclonal antibody targeting the CD20 epitope on the entire B cell lineage...

..She has been followed for more than 27 years with stable visual function and neuroimaging findings. Bilateral ONSMs, although usually described as aggressive in nature, may follow a stable clinical course...

..The observed optic nerve head structural changes in this patient did not correlate with the markedly improved visual function. Visual improvement may occur in ethambutol optic neuropathy despite progressive structural changes...

..CONCLUSION: Infraorbital nerve palsy is a potential complication of laser in situ keratomileusis. Symptoms improve but may persist...

..CONCLUSION: In this small series, the use of n-BCA either alone or in conjunction with detachable coils was a safe and effective technique for the treatment of symptomatic patients presenting with complex dCCFs...

..CONCLUSION: Most patients with bilateral optic disc edema and severe arterial hypertension maintained visual acuity of 20/50 or better in at least one eye...

..CONCLUSIONS: The a-wave latency is determined solely by the activity of the photoreceptors. A prolonged latency would indicate that the photoreceptors are damaged over a large area of the retina...
