Despite the extensive use of visual acuity measurement, visual acuity is often not reported in referrals into ophthalmology services, 2 possibly due to uncertainty relating to measurement conditions and reporting protocols for visual acuity.
To compare the measurements of visual acuity (VA) results measured with Snellen and Early Treatment Diabetic Retinopathy Study ETDRSS) charts in eyes with and without age-related macular degeneration (AMD).
All participants underwent detailed ophthalmologic screening examination, including measurements of visual acuity by Golovin-Sivtsev chart, cycloplegic skiascopy, measurements of intraocular eye pressure (IOP) and dilated eye fundus examination.
Exclusion criteria for both sets of measurements included visual acuity worse than 6/60 measured using the ETDRS chart, any self-reported history of ocular pathology and the use of contact lenses rather than spectacle correction.
Currently, 3 types of accommodating IOLs are commercially available: 1CU (HumanOptics), BioComFold (Morcher), and AT-45 Crystalens (eyeonics, Inc .. We present a meta-analysis of the peer-reviewed data from studies of these IOLs that use optic-shift measurements and visual acuity as the main outcome measures.
The aim of this study was to evaluate whether determination of cylinder power by Fourier analysis facilitates measurements of visual acuity and refraction in eyes after penetrating keratoplasty.
Measurements of visual acuity using the iPad are highly susceptible to glare.
Estimates of logMAR are from a mixed model using all available measurements of visual acuity which come from the best seeing eye in all cases.
In the 5.8% (72/1241) of patients who had an eye operation in the best seeing eye during follow up, measurements of visual acuity made after the operation were excluded from the analyses.
The comprehensive ophthalmical evaluation included: measurement of visual acuity and BCVA; IOP measurement using Goldmann applanation tonometry; slit lamp examination; fundus examination with a 90D lens; measurement of axial ocular dimension using ocular biometry (IOLMaster, Zeiss, Germany); and autorefractometry examinations.
