Abstract: Aim: To describe the distribution of different strabismus subtypes and identify potential risk factors. Methods: A telephone-based survey, interviewing guardians of known strabismus’ patients, diagnosed and followed at King Abdulaziz University Hospital, in Jeddah-Saudi Arabia. Results: We included (113) patients with a mean age at diagnosis of (49.37±52.41) months. Males constituted (50.4%), and most participants were Saudi nationals (64.6%). The top three subgroups encountered were (58.4%) Esotropia, (28.3%) Exotropia and (10.5%) Hypertropia, (1.8%). A positive past medical history of conditions such as hydrocephalus or congenital anomalies, was associated with developing strabismus (P=0.0001). No significant difference detected between the subgroups for the different modes of delivery, nor for an eventful neonatal history. Half of the participants were born into families with positive parents’ consanguinity, and higher strabismus rates were significantly associated with a positive family history. (P=0.0001). Maternal past medical history of chronic conditions or an eventful antepartum history was not associated with developing strabismus. Conclusion: Congenital anomalies, hydrocephalus, and past family history were associated with developing strabismus. There is a need to install a screening tool for early detection of this disorder.
