The Rarebit Fovea Test - a new measure of visual function
Visual acuity (VA) measurement by the use of letter charts is the most frequently used method for testing foveal function. However, since a decimal visual acuity of 1.0, often used as limit for normality, can be achieved with less than two-thirds of the normal number of optic nerve axons, the letter chart test cannot be regarded as sensitive to low-degree damage. The reason why letter charts ar...
متن کاملRarebit perimetry in normal subjects: test-retest variability, learning effect, normative range, influence of optical defocus, and cataract extraction.
PURPOSE To study normative ranges, learning effect (LE), test-retest variability (TRV), and influence of blur and cataract in normal subjects by using rarebit perimetry (RBP). METHODS Seventy-five normal subjects underwent visual field (VF) testing with standard automated perimetry (SAP) and RBP. LE and TRV for RBP were assessed in repeated examinations conducted on four different days. LE wa...
متن کاملCorneal thickness and endothelial density before and after cataract surgery.
BACKGROUND/AIMS Deturgescence of the corneal stroma is controlled by the pumping action of the endothelial layer and can be monitored by measurement of central corneal thickness (pachymetry). Loss or damage of endothelial cells leads to an increase in corneal thickness, which may ultimately induce corneal decompensation and loss of vision. Little is known about the effect of moderate reductions...
متن کاملProbing glaucoma visual damage by rarebit perimetry.
AIM To compare rarebit perimetry (RBP) with standard achromatic perimetry (SAP) in detecting early glaucomatous functional damage. METHODS 43 patients with ocular hypertension (OH), 39 with early primary open angle glaucoma (POAG), and 41 controls were considered. Visual fields were assessed using the Humphrey field analyser (HFA) 30-2 and RBP tests. Differences among the groups were evaluate...
متن کاملSubjective quality of vision before and after cataract surgery.
OBJECTIVE To investigate the effect of cataract surgery on subjective quality of vision. METHODS The Quality of Vision (QoV) questionnaire (Italian translation) was completed before and 3 months after cataract surgery in 4 groups of patients recruited from September through December 2010: first eye with ocular comorbidity, first eye without ocular comorbidity, second eye with ocular comorbidi...
