What is the potential consequence of untreated amblyopia?

1. Color blindness

2. Permanently impaired vision

3. Improved depth perception

4. Enhanced visual acuity

The correct answer is: Permanently impaired vision

Untreated amblyopia, often referred to as "lazy eye," can lead to permanently impaired vision in the affected eye. This condition typically arises during childhood when the brain does not fully develop connections to one eye, often due to misalignment, significant differences in prescription between the eyes, or other visual impairments. When left unaddressed, the brain may favor the stronger eye over the weaker one, leading to a decline in function and visual clarity in the amblyopic eye. As a result, the individual may experience long-term consequences including difficulty with tasks that require depth perception and overall diminished visual experiences. Treatment during the critical period of visual development is crucial, as after this period, the brain may not respond to interventions aimed at improving the vision in the weaker eye, leading to lasting impairment. While color blindness and improved depth perception do not stem from amblyopia, and enhanced visual acuity would typically result from proper treatment, the absence of appropriate intervention during childhood is what predominantly results in the risk of permanent issues with visual performance.
