When a squint signals something more

A seemingly innocuous squint or glare may initially seem harmless, but even minor eye issues should not be dismissed. In Malaysia, two prevalent conditions often linked to this symptom are strabismus, commonly referred to as a squint, and cataracts. Strabismus occurs when the eyes are not properly aligned, causing one eye to point in a different direction than the other.

This misalignment can lead to various complications, including poor depth perception, learning difficulties, and lower self-esteem. Dr Fazilawati Qamarruddin, a consultant ophthalmologist and paediatric ophthalmologist, highlights that strabismus can affect individuals of any age and may result from refractive errors, nerve disorders, or even trauma.

While glasses can often correct the issue in children, sudden appearance of a squint warrants immediate medical attention. Untreated strabismus may lead to amblyopia, or lazy eye, where the brain favors the stronger eye and the weaker one fails to develop properly. Early detection through routine eye examinations is crucial in preventing severe consequences.

As for cataracts, they predominantly affect older adults but can also surface earlier in certain cases. These conditions occur when the eye's natural lens becomes cloudy, resulting in blurred vision, glare, and altered color perception. Regular eye assessments are essential, especially for those with diabetes or prolonged UV exposure, as modern cataract surgery is minimally invasive and has a swift recovery time.

The modern surgical technique, phacoemulsification, involves using ultrasound to remove the cloudy lens, which is then replaced with an artificial one. Patients typically resume light activities within a week, with full visual recovery achieved in about two weeks.

In today's digital age, factors such as smoking, uncontrolled diabetes, and excessive screen time pose significant risks to eye health. Simple habits, like adhering to the 20-20-20 rule—taking a 20-second break from screens every 20 minutes and looking at something 20 feet away—can help mitigate these risks. Furthermore, spending time outdoors and wearing UV-protective sunglasses can significantly lower the chances of developing cataracts and other eye diseases.

Early detection remains the cornerstone of effective eye care, as many eye conditions progress slowly and silently. Routine eye examinations, especially starting around age 40, can help identify potential issues before they significantly impact vision, learning, mobility, and overall quality of life.
