- Abstract
Purpose: To report the findings in 3 cases of bilateral negative electroretinograms (ERGs) with acute onset of photophobia.Study design: Retrospective case series.Methods: The medical charts of the 3 patients were reviewed.Results: A 43-year-old woman, a 68-year-old woman, and a 41-year-old woman were referred to Nagoya University Hospital. Their main symptom was bilateral acute photophobia. None of the patients had any systemic diseases or specific medical history. The decimal best-corrected visual acuity (> 0.8) and Humphrey visual fields (mean deviation > -3 dB) were relatively well preserved in all 3 patients. The optical coherence tomography (OCT) and fundus autofluorescence findings were essentially normal. Fluorescein angiography showed mild leakage in 1 patient but no abnormality in the other 2 patients. However, the ERGs of the 3 patients had the features of abnormal ERGs found in patients with incomplete congenital stationary night blindness (CSNB). Exome analyses found no pathogenic variants related to known CSNB-related genes. The symptoms and ERGs of the 3 patients have not progressed or recovered after a relatively long follow-up period.Conclusion: The ERG characteristics of 3 patients with bilateral photophobia were similar to those of incomplete CSNB, suggesting post-phototransductional abnormalities. The symptoms and genetic analyses indicated the possibility of an acquired condition rather than a hereditary retinal disease.
