The Treatment of Esodeviation with Abduction Deficiency Caused by Recurrent Pterygium

ABSTRACT

The recurrent pterygium can be caused by repeating excisions for simple pterygium. The severe conjunctival cicatrization on the area of the medial rectus muscle limits abduction and results in diplopia and it is one of the causes of acquired retraction syndrome. We experienced two patients who have marked abducticn limitation and diplopia in all directions of gaze by recurrent pterygium. In order to eliminate these troblesome symptoms and signs with only one surgery, we performed conjunctival autograft transplantation in one patient and on the other patient with bilateral recurrent pterygium, the procedure was performed with resection of the lateral rectus using adjustable suture at one time. The limitation of ocular movement and diplopia were completely gone postoperatively.
