Sunway city: Early eye screening is crucial in detecting conditions such as squinting and cataracts before they lead to lifelong visual impairment, particularly among children and older adults, according to an eye specialist.
According to BERNAMA News Agency, Consultant Ophthalmologist and Paediatric Ophthalmologist at Sunway Medical Centre, Dr Fazilawati A Qamarruddin, highlighted that squinting or strabismus and cataracts are among the most common yet often overlooked eye conditions affecting Malaysians across different age groups. She explained that squinting occurs when the eyes are misaligned, with one eye pointing in a different direction from the other, impacting vision, depth perception, learning, and confidence.
Dr Fazilawati noted that squinting often arises from uncorrected refractive errors but may also result from nerve problems, neurological deficits, trauma, or tumors in the brain or orbits. She emphasized the importance of seeking medical attention promptly if double vision occurs in adults, especially to rule out any tumors.
Globally, studies estimate that between two and four per cent of children have strabismus, translating into thousands of Malaysian children. Many cases remain undetected until academic performance or social confidence is affected. Dr Fazilawati warned that untreated squinting could lead to amblyopia, or lazy eye, where the brain begins to favor the stronger eye, resulting in reduced vision.
She recommended that children undergo vision screening by the age of three and again before entering primary school. She emphasized that refractive errors are common in Malaysia and can often be corrected with prescription glasses if detected early. Parents should be alert to signs such as head tilting, frequent squinting, sitting too close to the TV, or complaints of headaches.
Regarding cataracts, Dr Fazilawati stated that the condition is commonly associated with aging, typically affecting individuals over 60. However, it may develop earlier in people with diabetes, smokers, and those exposed to sunlight. Cataracts can cause cloudy vision, glare, faded color perception, and difficulty driving at night, but modern surgical techniques have improved treatment outcomes significantly.
Dr Fazilawati explained that modern cataract surgery uses the phacoemulsification technique, which employs ultrasound to break up the cloudy lens through a small incision, allowing quicker recovery. Many cases can be done as day surgery, with most patients returning to light activities within a week and full visual recovery typically within two weeks.
She also highlighted the impact of prolonged screen time, particularly among children and teenagers, which may contribute to worsening short-sightedness. She advised practicing the 20-20-20 rule to reduce eye strain. Additionally, she urged adults to undergo eye examinations from the age of 40 and advised annual eye screenings for those with diabetes to detect diabetic retinopathy early.
Dr Fazilawati concluded by stressing that early detection supports better learning, independence, and quality of life, warning that postponing exams can lead to missed opportunities for simple treatment.
