The Effects of Occlusion Therapy in Patients With Anisometropic Amblyopia Aged 8 Years and Older

Purpose:To evaluate the factors affecting successful occlusion treatment and visual recovery time in patients with amblyopia when best corrected visual acuity (BCVA) improved up to 1.0 after occlusion. Methods: Forty-eight patients aged 2 to 13 years old with amblyopia due to refractive errors or strabismus were selected. The duration of treatment needed to achieve a BCVA of 1.0 was compared according to the cause of amblyopia (anisometropia, strabismus, combined), initial BCVA of the amblyopic eye, and the age at treatment, as well as other factors. Results: The mean age of amblyopic treatment was 5.4 years old and the mean duration of treatment was 22.9 months. The duration of treatment was longer in children whose initial BCVA was lower than 0.2, those with spherical equivalent of the amblyopic eye higher than +3.0D and those older than 6 years old. However, there were no significant differences according to the cause of amblyopia. Conclusions:The duration of treatment needed to achieve a BCVA of 1.0 was prolonged when the initial BCVA in the amblyopic eye was lower than 0.2, the age at treatment was more than 6 years old, or the spherical equivalent of the amblyopic eye was higher than +3.0D at treatment. These factors can be used to predict the duration of occlusion treatment.

We used a questionnaire to explore perceptions and clinical practice patterns of Korean pediatric ophthalmologists in terms of amblyopia. Methods: From September to November 2018, we conducted a web-based questionnaire survey of 99 specialists of the Korean Association for Pediatric Ophthalmology and Strabismus who operated ophthalmology clinics in Korea. We received 56 responses (56.57%) and retrospectively analyzed the data. Results: The average specialist age was 44.0 ± 9.7 years. The mean age of treated amblyopia patients was 3 to 5 years (69.6%); the most common amblyopia was refractive anisometropic amblyopia (75.0%). On average, treatment commenced at 4 years of age (53.6%); child and parent cooperation most significantly influenced treatment success (46.4%). The preferred test was cycloplegic refraction (96.4%) and the preferred treatment occlusion therapy (100%) with glasses correction (98.2%). Occlusion therapy was most commonly performed for 2 hours/day (69.6%); the minimum age for eyeglasses prescription was 2.10 ± 1.18 years. Only three respondents (5.36%) prescribed contact lenses and only one (1.79%) performed refractive surgery. Conclusions: In Korea, amblyopia treatment is based on occlusion therapy and glasses correction. However, the time of treatment commencement, the duration of occlusion therapy, and the glasses used for correction varied. It is necessary to develop guidelines for amblyopia treatment; these should reflect current medical conditions.
