Abstract
- A cyclic squint is a rare, interested in ocular motility disturbance. It appears regular and alternate-day rhythmic cycle, most frequently at 48 hours The cyclic squint was reviewed approximately 50 Cases in literatures since it was first reported by Burian in 1958. These all was presented with cyclic ESOTROPIA but authors have not found a description of cyclic EXOTROPIA as described here. The biological clock mechanism which induces a cyclic squint is unknown. This case had recession of the bi-lateral recti and obtained constant orthophoria.
