In simple words: Exotropia is a type of strabismus (eye misalignment) where one eye turns outward.Normally, both eyes look straight ahead. With exotropia, one eye deviates towards the temple. This can cause problems with vision, such as double vision or impaired depth perception.

A form of ocular misalignment where the visual axes diverge inappropriately. For example, medial rectus muscle weakness may produce this condition as the affected eye will deviate laterally upon attempted forward gaze. An exotropia occurs due to the relatively unopposed force exerted on the eye by the lateral rectus muscle, which pulls the eye in an outward direction.

Example 1: A 6-year-old child is brought to the ophthalmologist because one eye turns outwards intermittently. After a comprehensive eye exam, the diagnosis of intermittent exotropia is made., A 30-year-old adult experiences double vision and eye strain. An ophthalmologist diagnoses constant exotropia, which developed after a recent head injury., An infant is noted to have a constant outward deviation of one eye. Following a pediatric ophthalmology evaluation, congenital exotropia is confirmed.

Documentation should include a detailed description of the deviation, including frequency (constant or intermittent), laterality (which eye is affected), and any associated symptoms like double vision or eye strain. Measurements of the deviation angle using prisms, as well as assessment of visual acuity and binocular function, are essential. Any underlying medical conditions or prior treatments should also be documented.
