Aim: To investigate the prevalence of strabismus by age groups in Caucasian Macedonian population.
Methods: A study population of 1900 patients (aged 0-86 years) from the capital city, Skopje, Macedonia, were analysed in a secondary health institution in the central urban area. Ophthalmological examination included: visual acuity, slit- lamp biomicroscopy, autorefraction, and ocular motility examination.
Results: In our retrospective cohort (1900), 60 patients did have strabismus (3.2%). The highest prevalence of strabismus was in primary school children (10-14 years- 20.2 %; 0-4 years- 16.2 %; 15-19 years- 11.8% and 5-9 years- 8.6%). Our adult population showed results similar to Caucasian Danish population with prevalence of strabismus of 0.7% (age group 50-54 years) and 0.8 % (age group 55-59). The most frequently identified subtype was esotropia (73.3%), followed by exotropia (23.4%) and cyclovertical strabismus (3.3 %).
Conclusion: The overall prevalence of strabismus on Macedonian cohort was 3.2%. Our results on primary school children are much higher than other studies on Caucasian and Asian population, but similar to prevalence in the population in Saudi Arabia. The most prevalent type of strabismus was esotropia (73.3%). Regarding gender distribution, both esotropia and exotropia were more frequent in males.
