Evaluation of visual acuity measurements after autorefraction vs manual refraction in eyes with and without diabetic macular edema.
OBJECTIVE To compare visual acuity (VA) scores after autorefraction vs manual refraction in eyes of patients with diabetes mellitus and a wide range of VAs. METHODS The letter score from the Electronic Visual Acuity (EVA) test from the electronic Early Treatment Diabetic Retinopathy Study was measured after autorefraction (AR-EVA score) and after manual refraction (MR-EVA score), which is the...
متن کاملComputerized method of visual acuity testing: adaptation of the amblyopia treatment study visual acuity testing protocol.
PURPOSE To report a computerized method for determining visual acuity in children using the Amblyopia Treatment Study visual acuity testing protocol. METHODS A computerized visual acuity tester was developed that uses a programmed handheld device that uses the Palm operating system (Palm, Inc, Santa Clara, California). The handheld device communicates with a personal computer running a Linux ...
متن کاملThe precision of wavefront refraction compared to subjective refraction and autorefraction.
PURPOSE To determine the precision (repeatability) of several methods of calculating refraction from higher-order wavefront aberration data and to compare these wavefront refractions with lower-order (LO) wavefront refraction, subjective refraction, and autorefraction. METHODS Four clinicians refracted 16 normal participants aged 23.6 +/- 1.2 years, 69% female with an average spherical equiva...
متن کاملManifest refraction versus autorefraction for patients with subfoveal choroidal neovascularization.
PURPOSE To compare the results from manifest refraction using trial lenses and a standard visual acuity protocol to results from autorefraction for obtaining refractive error and best corrected visual acuity in patients enrolled in a randomized clinical trial. METHODS During a 4-month period, 29 patients with subfoveal choroidal neovascularization (CNV), who were enrolled in the Submacular Su...
متن کاملSymptomatic Rathke’s Cleft Cyst Presenting With Decreased Visual Acuity
Background and Importance: Symptomatic Rathke’s cleft cyst is a rare lesion that often presents without any symptoms. Case Presentation: We report a 40-year-old female with symptomatic Rathke’s cleft cyst located in the sellar and suprasellar region. She presented with visual disturbance, headache, weight gain, hypothyroidism and amenorrhea. The patient underwent surgery and ...
