Refractive adaptation
WebBlur adaptation can be observed as an improvement in vision under degraded conditions, and these changes occur relatively rapidly following exposure to blur … The human visual system is amenable to a number of adaptive processes; one such process, or collection of processes, is the adaptation to blur. WebPurpose: To investigate whether the gradual improvement in unaided visual acuity commonly seen after laser refractive surgery is attributable, in part, to neural adaptation to blur. Methods: Unaided logMAR visual acuity was measured at presentation (blur adapted) and immediately after refraction and removal of refractive correction (correction …

Evaluation of spectacles alone as T/T for anisometropic amblyopia in children between 3 & 7 years 33-50% pts showed resolution of amblyopia: rest required occlusion after 2 months. WebIt has been established that refractive adaptation alone can significantly enhance visual acuity. However, the duration of optical correction varies between studies and the …
WebThis is expected, as by 4 months, refractive adaptation should be asymptotic for most observers. 3 A partial correlation analysis with age and correction time controlled also showed no significant correlation between the degree of anisometropia and the balance point in the corrected anisometropes: rpartial = −0.16, P = 0.45. WebFor patients who required refractive correction or whose refractive correction needed updating (), a 2-month period of refractive adaptation was provided before the inverse occlusion. (a) Binocular balance was measured with the binocular phase combination task and expressed as the interocular contrast ratio (amblyopic eye/fellow eye) when the ...
WebMany insights about vision have come from this use of adaptation, as a method. A second important trend has been the realization that the processes of adaptation are themselves essential to how vision works and thus likely operate at all levels. That is, … WebConclusion: Refractive adaptation is a distinct component of amblyopia treatment. To appropriately evaluate mainstream therapies such as occlusion and penalisation, the …
