The three important variables were: with simple cataract, the preoperative visual acuity in the cataractous eye, as evaluated by the ophthalmologist; the subjective visual function reported by the patient; and in some cases the surgical complexity.
This study represents achievement of the most substantial restoration of visual function reported to date in an animal model of achromatopsia using a human gene construct, which has the potential to be utilized in clinical trials.
With cataract, this improvement should not only correlate with improved visual acuity (either measured by Snellen or lines of improvement or changes in the log MAR visual acuity), as reported by the ophthalmologist, but also with a relevant improvement in visual function, as reported by the patient.
Therefore, visual function has been reported by different studies as a key variable from the patient perspective [ 18].
Both of these abstracts refer inappropriately to QoL while actually reporting visual function.
Main outcome measure Ocular safety (ocular examinations, visual function tests, participants' reports of adverse events, and visual disturbance questionnaire completed by investigators) by treatment group at 12 weeks, 24 weeks, 18 months, and yearly.
Additionally, data were collected on demographics; medical history; medications; knowledge, beliefs, and behaviors related to diabetes; usual diet; physical activity (10-day pedometer log); visual function and self-report of eye exam in the last year; health utilities; and cost.
We examined the association between visual impairment and self reported visual function in a population sample of older people in the UK.
Improvements in visual function have also been reported following transplantation of multipotent retinal progenitor cells derived from green fluorescent protein (GFP -expressing mice [ 13].
It has been shown that refractive correction of vision ≤6/9 among rural schoolchildren in Mexico led to significant improvement in self reported visual function.
