Abstract
Objective: To find out the prevalence of various types of amblyopia in patients of different age groups.
Study design: It is a descriptive cross sectional hospital based study.
Place and duration of study: A Six-month study was carried out in Department of Ophthalmology, Eye OPD, Holy Family Hospital, Rawalpindi . (from April 2022 till September 2022)
Material and Methods: Fifty patients were studied for the research purpose. Detailed examinations were performed including history taking, slit lamp examination, vision and refraction and fundoscopy. Orthoptic assessment was done on patients presented with the complaint of deviation. Patients who were performed with cycloplegic refraction were called on a follow up for the post mydriatic test (PMT).
Results: Out of the 50 amblyopic patients presented in the refraction room, ametropic amblyopia was seen as the most frequent type of amblyopia. As per data, 22 out of 50 patients had ametropic amblyopia. Meridonial amblyopia came out to be the second most frequent type with 13 patients followed by anisometropic amblyopia that had 8 patients. 5 of the patients had strabismic amblyopia and 2 were presented with deprivation amblyopia.
Conclusion: Ametropic amblyopia is the most common type of amblyopia. It is more frequently seen in males than females. Although amblyopia develops in early childhood, the age group in which ametropic amblyopia is frequently presented in the eye OPD is 11-16 years of age and then 5-10 years of age.
Keywords: Amblyopia, anisometropic amblyopia, ametropic amblyopia, deprivation amblyopia, meridonial amblyopia, strabismic amblyopia, patching therapy.
