BACKGROUND AND OBJECTIVE: To determine the ultra-wide-field fundus autofluorescence (UWFFAF) and optical coherence tomography (OCT) features of syphilitic outer retinopathy (SOR). PATIENTS AND METHODS: Retrospective chart review. RESULTS: Three patients with SOR were investigated. Treatment with parenteral penicillin led to improvement of outer retinopathy, visual acuity, and symptoms. UWFFAF showed speckled hyperautofluorescence, hypoautofluorescence, and normal autofluorescence, similar to what has been described as a trizonal pattern in acute zonal occult outer retinopathy (AZOOR) in the chronic case of SOR, but with hyperautofluorescent areas in the two acute cases...

Solar retinopathy is a rare clinical entity caused by photochemical damage to the retinal pigment epithelium layer and photoreceptors of the fovea. Here we describe a case of a 33-year-old female patient diagnosed by near-infrared fundus autofluorescence imaging for signs of damage to the melanosomes of the retinal pigment epithelium of the fovea. The patient was advised to discontinue looking at the sun with the naked eye.

PURPOSE: Iron can exert oxidative damage, and increased accumulation is believed to play a role in age-related macular degeneration. Hereditary hemochromatosis leads to an increase in total body iron. Patients with HH were assessed for drusen and other retinal changes. METHODS: Descriptive uncontrolled study of spectral-domain optical coherence tomography, short-wavelength autofluorescence, and color fundus images from patients with HH were used. Diagnosis of HH was established by measuring ferritin and transferrin saturation, and confirmed by genetic testing...

We conducted a systematic review of the accuracy of fundus autofluorescence (FAF) imaging for diagnosing and monitoring retinal conditions. Searches in November 2014 identified English language references. Sources included MEDLINE, EMBASE, the Cochrane Library, Web of Science, and MEDION databases; reference lists of retrieved studies; and internet pages of relevant organisations, meetings, and trial registries. For inclusion, studies had to report FAF imaging accuracy quantitatively. Studies were critically appraised using QUADAS risk of bias criteria...

Importance: Steroid 5α-reductase type 3 congenital disorder of glycosylation (SRD5A3-CDG) is a rare disorder of N-linked glycosylation. Its retinal phenotype is not well described but could be important for disease recognition because it appears to be a consistent primary presenting feature. Objective: To investigate a series of patients with the same mutation in the SRD5A3 gene and thereby characterize its retinal manifestations and other associated features. Design, Setting and Participants: Seven affected individuals from 4 unrelated families with early-onset retinal dystrophy as a primary manifestation underwent comprehensive ophthalmic assessment, including retinal imaging and electrodiagnostic testing...

A 17-year-old girl presented with unilateral retrobulbar optic neuritis as well as bilateral funduscopic findings and outer retinal dysfunction suggestive of acute zonal occult outer retinopathy (AZOOR). Fundus autofluorescence abnormalities, visual field loss, and electroretinographic changes were supportive of bilateral AZOOR. MRI was consistent with the diagnosis of clinically isolated syndrome (CIS), which is defined as a central nervous system demyelinating event that may herald the onset of multiple sclerosis (MS)...
