Monocular eye closure following treatment of intermittent exotropia
Reviewed by Fiona Rowe

The purpose of this study was to evaluate the short- and long-term status of monocular eye closure after surgical treatment of intermittent exotropia and to determine whether the status at short-term postoperative follow-up duration remains or can change after long-term follow-up duration. This was a retrospective review of 37 intermittent exotropia surgical cases; 18 males and 19 females with mean age of 10.6 ±6.1 years. All closed their non-dominant eye in sunlight reducing to 35% with <6 months of follow-up and 65% with follow-up of 7.2 ±2.9 years. Monocular eye closure disappeared in 43% and persistent closure remained in 57%. There was no significant difference between these groups. The authors acknowledge the retrospective study design, small case numbers and that unmasked investigation could introduce bias.
