occlusion amblyopia

A form of stimulus deprivation amblyopia that develops when an eye is constantly occluded for an extended period, particularly during the critical period of visual development. The obstruction of visual stimuli to the retina leads to abnormal development of the visual cortex, resulting in reduced visual acuity and contrast sensitivity in the affected eye. Occlusion amblyopia can occur due to various causes, such as congenital ptosis or media opacities.
