Binocular visual acuity for the correction of spherical aberration in polychromatic and monochromatic light.
Correction of spherical (SA) and longitudinal chromatic aberrations (LCA) significantly improves monocular visual acuity (VA). In this work, the visual effect of SA correction in polychromatic and monochromatic light on binocular visual performance is investigated. A liquid crystal based binocular adaptive optics visual analyzer capable of operating in polychromatic light is employed in this st...
متن کاملVisual acuity and excitement.
Viewed within the framework of activation theory, individuals with low visual acuity might conceivably be seen as persons with low preferred levels of activation who seek to reduce stimulus input in order to maintain activation at their preferred level. It was hypothesized, therefore, that persons with low visual acuity would demonstrate less receptivity to environmental stimulation than highac...
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 ...
متن کاملVisual Acuity Before and After Occlusion Therapy in Children and Adolescents (Aged 5-13 years) Amblyopia
Purpose: To evaluate the effect of occlusion therapy on visual acuity in children and adolescents (aged 5-13 years) with amblyopia. Methods: This experimental study followed a pretest-posttest design. Totally, 72 people with amblyopic eyes (visual acuity between 20/100 and 20/25) were selected through convenient sampling. The visual acuity was assessed at 1, 3, and 6 months after starting occlu...
متن کاملCorrelation between Visual Acuity and Optical Coherence Tomography-Measured Retinal Thickness in Diabetic Macular Edema
Background and Objective: Diabetic macular edema (DME) is one of the common complications of diabetes which significantly accounts for preventable visual impairment and blindness. Central macular thickness (CMT) is a feature found in DME patients. This study aims to determine the relationship between optical coherence tomography (OCT)-measured CMT and visual acuity (VA) in patients with DME bef...
