Abstract


Objective: To describe the clinical profile of patients with amblyopia seen at a Philippine tertiary hospital.

Methodology: This was a cross-sectional study utilizing a chart review of children ages 6 months to 18 years old diagnosed with amblyopia at a Philippine tertiary hospital. Records with complete entry of history and ocular examinations were included. Verbal children with best-corrected visual acuity in both eyes of less than 6/15 or a 2 line difference between eyes were considered amblyopic. Response to alternate occlusion or refixation patterns was used as a basis for diagnosing amblyopia in pre-verbal children. Patients with visual deprivation amblyopia such as from cataract who had undergone lens extraction and optical correction were included.

Results: There were 334 patients included in the study. The mean age was 5±3 years with 52% being male. Deprivation type of amblyopia was present in 192 (58%) patients, strabismic type in 81 (24%), and refractive type in 61 (18%). No sex predilection was observed. Majority of the patients were 3-6 years old on initial consult. Cataract was the most common cause of deprivation amblyopia affecting 127 (66%) patients. Strabismic amblyopia was present in 58 patients with 74% being esotropic. Anisometropic refractive amblyopia was more common at 37 (58%) than isometropic refractive amblyopia.

Conclusion: Visual deprivation amblyopia was the most common cause of amblyopia in a Philippine tertiary hospital.
