Strabismus (Squint): Types, Causes, Sign and Symptoms and Management

It can be constant or intermittent and may lead to amblyopia (lazy eye) if untreated. Types of Strabismus Strabismus can be classified based on various factors, such as direction of eye deviation, constancy, cause, and association with ocular movements. Understanding these classifications is crucial for accurate diagnosis and management. 1. Based on Direction of Deviation A. Esotropia (Convergent Strabismus): One or both eyes turn inward. Subtypes: Accommodative Esotropia: Associated with hypermetropia; corrected by glasses. Non-accommodative Esotropia: Not corrected with glasses. Congenital Esotropia: Present before 6 months of age. B. Exotropia (Divergent Strabismus): One or both eyes turn outward. Subtypes: Intermi…
