What are potential complications of untreated eye infections?

Untreated eye infections can lead to serious consequences, including vision loss, scarring of the cornea or surrounding tissues, and even systemic infections that affect other parts of the body. Vision loss can occur due to damage to the structures of the eye, such as the cornea, retina, or optic nerve, particularly if the infection progresses without appropriate treatment. Scarring can cause lasting impairment in visual acuity and may require surgical intervention for correction. Furthermore, the pathogens causing eye infections can sometimes enter the bloodstream, leading to systemic infections that pose significant health risks beyond just the eyes.

In contrast, the other options do not accurately reflect the reality of untreated eye infections. Improved visual acuity over time is unlikely in the context of infection; infections typically impair rather than enhance vision. Reduced glare sensitivity might be a symptom seen in certain conditions but is not a direct outcome of an untreated infection. Permanent adjustments to eye prescriptions are generally based on refractive changes rather than infections. Hence, the understanding that complications from untreated eye infections could lead to serious and varied health issues underscores the importance of seeking prompt and effective treatment.
