Abstract:
Purpose: (1) To determine type of astigmatism in nystagmus subjects of age 5-15 years.
(2) To determine the magnitude of astigmatism in nystagmus subjects of age 5-15 years.
Study Design: Cross-sectional study
Sampling Technique: Non-probability convenient sampling
Place and duration of study: Pediatric outdoor patient department of AlIbrahim eye hospital (AIEH) Karachi, Pakistan from May to October, 2018.
Material and Method: This study included 52 eyes of 26 subjects age ranged from 5 to 15 years. Retinoscopy i.e. cycloplegic and non-cycloplegic both were performed. Cycloplegic retinoscopy was the preferred and acceptable option for young subjects as well as for nystagmus subjects.
Result: It was found that all the 52 eyes of 26 nystagmus subjects had astigmatism i.e. 100% astigmatism. Compound myopic astigmatism has been present most frequently i.e.20 eyes (38.46%) had compound myopic astigmatism,16 eyes (30.77%) had compound hyperopic astigmatism,14 eyes (26.92%) had mixed astigmatism and only 02 eyes (3.85%) had simple myopic astigmatism. The average amount of astigmatism was found to be2.45±1.08DC for right eyes and3.09±2.11DC for left eyes.
Conclusion: Astigmatism was 100% in nystagmus subjects and compound myopic astigmatism was the most common type
