Functional Visual Acuity of Early Presbyopia
PURPOSE To evaluate visual function in patients with early presbyopia using the functional visual acuity (FVA) test. METHODS This study included 27 eyes of 27 healthy older volunteers (mean age, 44.1 ± 2.6 years) and 14 eyes of 14 healthy young volunteers (mean age, 28.4±4.8 years). The distance-corrected visual acuity (DCVA), distance-corrected near VA (DCNVA), subjective amplitude of accomm...
متن کاملMesopic Functional Visual Acuity in Normal Subjects
To evaluate mesopic functional visual acuity (FVA) with a newly developed system in normal subjects and to compare the results with photopic FVA, sixty-eight healthy volunteers (24.03 ± 4.42 [mean ± standard deviation] years) were enrolled in this study. A commercially available FVA measurement system (AS-28; Kowa, Aichi, Japan) was modified to measure FVA under mesopic conditions as well as ph...

متن کاملImpaired functional visual acuity of dry eye patients.
PURPOSE To report dry eye patients' functional visual acuity, which was measured after sustained eye opening for 10-20 seconds, as a simulation of visual function of daily acts of gazing, which is defined as looking at an object with involuntary blink suppression. METHODS Interventional clinical nonrandomized comparative trial. We measured ordinary best-corrected visual acuity and functional ...
متن کاملFunctional Visual Acuity in Age-Related Macular Degeneration
PURPOSE We evaluated whether a functional visual acuity (FVA) system can detect subtle changes in central visual acuity that reflect pathological findings associated with age-related macular degeneration (AMD). METHODS Twenty-eight patients with unilateral AMD and logMAR monocular best corrected VA better than 0 in both eyes, as measured by conventional chart examination, were analyzed betwee...
