Early ‘Photoscreenings’ for Amblyopia Improve Visual Outcomes

By Judith Riddle
Senior Editor

TESTING INFANTS AND TODDLERS for amblyopia before age 2, using a method called photoscreening that involves taking flash pictures of the eye, yields better treatment outcomes than waiting until preschool age to perform visual acuity screenings, according to a study1 in the April 2008 issue of Archives of Ophthalmology.

Researchers said children screened before age 2 who were diagnosed with amblyopia had significantly better visual acuity at age 6 than children tested later. Despite a similar level of risk factors for amblyopia, 95% of screened infants and toddlers had 20/40 vision after treatment, compared with 83% of those tested between the ages of 2 and 4, the study reported.

These results demonstrate the importance of discussing amblyopia screening and treatment options with parents of infants and toddlers. You also can use the photoscreening method to diagnose amblyogenic risk factors, such as strabismus, anisometropia, high refractive error and even cataracts, researchers said.

Maximizing Silicone Hydrogel Lens Comfort
Converting hydrogel contact lens wearers to silicone hydrogels is a challenge for many practitioners because of the unexpected patient complaints of lens awareness and discomfort. While the stiffer lens modulus of silicone hydrogels plays a role, the key to maximizing lens comfort is assessing the health of the upper eyelids. Everting the upper lids of hydrogel wearers can reveal inflammatory conditions, such as low-grade giant papillary conjunctivitis or lid wiper epitheliopathy. These conditions tend to be asymptomatic in hydrogel wearers but symptomatic in silicone hydrogel wearers, leading to lens intolerance. Treating these inflammatory lid conditions before converting patients to silicone hydrogels will ensure lens comfort and increased wearing time.
