Amblyopia , known as “lazy eye”, is a major cause of vision problems in children and a common cause of blindness in people aged 20 to 70 in developed countries. In amblyopia the person’s stronger eye is favored and his/her weaker eye gradually loses visual power as a result. When the condition is detected and treated before age 7, more than 75 percent of children achieve 20/30 vision or better, the Amblyopia Treatment Study reports. But parents and teachers can easily miss this problem-especially in very young children. Pediatric ophthalmologists (Eye M.D.s), pediatricians, family doctors and educators are looking for the best, most cost-effective ways to detect amblyopia as early as possible. October’s Ophthalmology journal reports on the use of photoscreening to detect amblyopia in children aged 6 months to 6 years.
More than 147,000 children were screened between 2000 and 2009. Photoscreening technology was used because earlier studies indicated problems with using eye charts to screen children younger than age 3 and children with disabilities. This study used the Medical Technology, Inc. (MTI) PhotoScreener, which records the pattern of light reflected through each of the child’s pupils as the child’s eyes are photographed. Other studies of normal and high-risk children found the MTI effective for screening for amblyopic risk factors, which include: unequal visual acuity between the two eyes (anisometropia), high nearsightedness, high farsightedness, astigmatism, and strabismus (eye turned inward or outward).
Amblyopia is usually treated with special eyeglasses, patching of the stronger eye, medications, or a combination of approaches.
