While visual improvements with partial and full hyperopic correction are equally good in children, considerations for full correction differ for children older than 5 years and those younger, a study found.

A questionnaire based on self-reported symptoms may help clinicians identify patients with warning signs of depression, and the test may be especially useful for patients with low vision because they are at high risk of poor mental health status.

A higher degree of myopia and hyperopia was associated with larger cup-to-disc ratio in patients with anterior ischemic optic neuropathy. Overall, cup-to-disc ratio in those patients was significantly smaller than in the general population.

Diminished ability to detect small movements or reduced visual fields may result in difficulties with balance in older adults, researchers have found. Their study is believed to be the first large-scale analysis of population-based data to gauge the extent to which visual function and motion detection affect balance.

Visual defects caused by retinal lesions appeared to improve after 6 months of computer-based systematic vision stimulation, a small study found.

Three methods of measuring amplitude of accommodation showed widely varying degrees of repeatability, a key factor in gauging significant accommodative changes. The methods are not interchangeable, the study authors said.

ATLANTA — A computer-based treatment improved best corrected visual acuity and contrast sensitivity in patients older than 10 years with unilateral amblyopia, according to study results presented here.

ATLANTA — Decreased vision is uncommon in preschool-aged children in both white and African-American populations, the Baltimore Pediatric Eye Disease Study found.

No clinically meaningful differences in axial length, corneal curvature or myopia were found between children wearing soft contact lenses and children wearing spectacles.

Data gathered in a prospective study support the practice of providing maximum hypermetropic correction in children with fully accommodative esotropia
