3 天之前 · The accommodative and binocular parameters were all measured under binocular vision status, and subgroups were divided according to norms derived from the literature of the normal population [17, 18]. To address inter-eye correlation, we used the mean value of measurements from both eyes in the statistical analysis.

5 天之前 · Purpose: To evaluate the repeatability and agreement of established and newer methods for measuring the amplitude of accommodation in non-presbyopic and early presbyopic individuals. Methods: The amplitude of accommodation of 81 participants was measured using five different methods (two push-up techniques, two minus lens techniques and one objective …

2 天之前 · Nocturnal myopia: Without adequate stimulus for accurate accommodation, the accommodation system partially engages, pushing distance objects out of focus. [ 71 ] Nearwork-induced transient myopia (NITM): short-term myopic far point shift immediately following a sustained near visual task. [ 74 ]

4 天之前 · It is due to the accommodation of the eye. The human eye can adjust its focal length according to the different distances. Therefore, the option (b) is correct. ... A normal eye is not able to see clearly the objects placed closer than 25 cm because the ciliary muscles have a limit of contraction and relaxation, to see closer objects, ciliary ...

5 天之前 · A key finding is that the brain glymphatic system is mainly disengaged during wakefulness but becomes highly active during sleep, particularly during non-rapid eye movement slow-wave sleep .

4 天之前 · Accommodation. Refers to the eyes' ability to focus on and track objects that are both close and far away.

3 天之前 · We report improved symptoms in an adult patient with accommodation disorder and convergence spasm following a combination of in-clinic and at-home orthoptic therapies, including vergence training, non-prism spectacles to relax accommodation, cycloplegic eye drops, and anti-suppression exercises. KEYWORDS: Spasm of accommodation;

2 天之前 · A 26-year-old patient was referred for further evaluation. The best-corrected visual acuity was 20/20 in the right eye and 20/25 in the left eye. Fundoscopy of the right eye was normal. The left eye showed whorled lesions adjacent to the fovea, extending temporally, and peripheral grouped congenital hypertrophy of the retinal pigment epithelium (A, B). OCT …

5 天之前 · Une grande majorité de personnes auront des amplitudes d'accommodation dans les limites normal pour leur âge. Cependant un petit nombre de patients présenteront des amplitudes faibles permettant de soulever un problème fonctionnel, lié à la fatigue, ou pathologique.

4 天之前 · Normal tension glaucoma is a silent threat to vision. It progresses without obvious warning signs, making early detection crucial. Since eye pressure stays within normal limits, many people remain unaware until significant damage has occurred. Regular eye exams are the best way to catch it early and start treatment.
