The prevalence of different types of strabismus among strabismic patients in Kazakhstan
Introduction: Strabismus is a very common pediatric ocular problem found in Kazakhstan and there is a lack of population-based data on its prevalence and types. This study presents the relative prevalence of various types of strabismus and other pathologic findings that might be associated with it.
Methods: This single-center, retrospective cohort study was performed using data from the archives of «Kazakh « Badge of Honour» research institute of eye diseases» LLP, Almaty, Kazakhstan, from 2018 to 2022. The study consisted of using records of strabismic patients. From these, strabismus types and associated abnormalities, types of amblyopia were recorded.
Results: In this study, 425 strabismic patients were studied who underwent strabismus surgery at the First Surgical Department of the Kazakh National Institute of Ophthalmology in Almaty, Kazakhstan. Nonaccommodative esotropia (ET) was the most prevalent type of strabismus accounting for 43.3% of all strabismic patients while intermittent exotropia (XT), nonaccommodative ET and hypertropia (HT), with 21.3%, 20.1% and 15.3%, respectively, were relatively common. The most common association with those types of strabismus was inferior oblique overaction accounting for 10% of all cases. Significantly 30% of patients had no amblyopia and 70% of patients had a combined type of amblyopia which was the most common type of amblyopia found in strabismic patients.
Conclusion: The study found that nonaccommodative esotropia (ET) was the most prevalent type of strabismus, accounting for 43.3% of all cases. The findings emphasize the importance of tailored treatment approaches that take into account the specific type of strabismus and the presence of amblyopia in order to provide the best possible care for these patients. Further research may be warranted to explore treatment strategies and outcomes in greater depth.
