This 5-year old boy was
referred because of left esotropia. Both eyes were straight until 2 years
ago when he developed a left orbital cellulitis which caused his left eye to
close for about a week. The visual acuity measured 6/6 in the right eye and
6/60 in the left eye. Refraction showed no significant ametropia. Patching
was performed and the vision improved to 6/18. Further improvement could not
be obtained with further patching. Squint surgery was carried out before the
patient entered the primary school. The post-operative result appeared
Left large angle esotropia.
The left eye could abduct normally
which excluded abducent nerve palsy as a cause.
