Abstract

Cyclic esotropia is a very rare form of esotropia, a particular clinical form of deviation related to the circadian cycle or biological clock. It is an acquired esotropia occurring in patients of all ages, though it is more frequent between 2 and 6 years of age –these patients alternate between straight eyes and esotropia every 24 to 48 hours-. It could be progressive and after some months or years of esodeviation it becomes constant in most of the patients. Although the most common cycle is 24 hours straight and 24 hour esotropia (alternate day esotropia), other forms of cyclic exotropia have been identified: cyclic oculomotor paralysis, cyclic nystagmus, periodic mydriasis, cyclic palpebral alterations and cyclic vertical deviations. A patient who arrived at the Pediatric Ophthalmologic Services with 24 hour cycles of ortotropia followed by increasingly long periods of esotropia is presented.
