Self-Reported Visual Function Index (VF-14) and Its Correlation with Best Corrected Visual Acuity in Elderly

Visual Acuity and Self-Reported Visual Function among Migrant Farmworkers.

PURPOSE Visual impairment presents significant risks for occupational injuries among farmworkers, a vulnerable population with limited access to vision care. Although previous research has noted farmworkers' low lifetime experience with vision screening and high rates of complaints of eye ailments and poor vision, there have been few screening data collected to evaluate these self-reports. The ...

Corneal collagen crosslinking in progressive keratoconus: Changes in corneal irregularity indices and correlation with the best spectacle-corrected visual acuity

METHODS: This is a retrospective uncontrolled study in eyes with progressive KC. In all 62 eyes from 48 patients, BSCVA, mean K, corneal irregularity at 3 mm and 5 mm were measured before CXL, at six months, and then annually until the last visit. For data analysis, patients were divided into three groups according to their mean preoperative K: group 1 included 12 patients with mean K value les...

Correlation 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...
