Purpose:
To describe the clinical features of patients from the Arabian Peninsula with Duane retraction syndrome (DRS).
Methods:
Retrospective chart review of patients referred to the King Khaled Eye Specialist Hospital in Riyadh, Saudi Arabia from 1982 to 2003 with a diagnosis of DRS. Patients having had prior strabismus surgery were excluded.
Results:
Of 404 DRS patients, 347 (86%) were unilateral, 57 (14%) were bilateral, and 111 (27%) had amblyopia. There were 221 (55%) females and 182 (45%) males. The Huber classification was as follows: 315 (78%) Type I, 16 (4%) Type II, and 77 (19%) Type III. Of the 57 bilateral cases, 25 (44%) were female and 32 (56%) were male.
Discussion:
Overall, the clinical features of DRS patients referred to a Riyadh eye hospital are similar to those reported in series throughout the world. However, our referred bilateral DRS patients are more commonly male. The clinical features of bilateral DRS deserve further worldwide study.
