Quantification of visual acuity: "Counting fingers" and "Hand movement" with the Berkeley Rudimentary Vision Test.

Purpose: This study aims to compare the results of the Finger Count Test (FCT) for "Counting fingers" (CF) and "Hand movement" (HM) with the visual acuity (VA) obtained from the Berkeley Rudimentary Vision Test (BRVT) in low vision patients with different pathologies.

Methods: Uncorrected visual acuity was estimated using BRVT and using the corresponding CF or HM in 38 low vision patients (VA range between 1.40 and 3.

A case report of isolated primary herpes-simplex virus neuroretinitis in an immunocompetent adult.

Background: Herpes simplex virus (specifically HSV-1 and HSV-2) are greatly prevalent viruses that can cause conjunctivitis, keratitis and other rarer ocular disorders such as acute retinal necrosis syndrome or neuroretinitis. We report a case of an isolated unilateral neuroretinitis with primary HSV infection in an immunocompetent adult without other related clinical features.

Case Presentation: A 60-year-old immunocompetent woman presented with sudden painless central vision loss in her left eye (best corrected visual acuity was 20/200) showing optic disc edema, submacular fluid and a delayed development of a macular star.
