To determine the prevalence of anisometropia and amblyopia in Duane retraction syndrome in patients referred to tertiary eye center (Ibn Al-Haitham Teaching Eye Hospital squint department). All recorded files of patients attended to Ibn-Al Haitham Teaching Eye Hospital between 2009 and 2015, were retrospectively reviewed, a total number of 5000 files, 120 patients with the diagnosis of Duane retraction syndrome were identified. The prevalence of the Duane retraction syndrome in our study related to strabismus population was 2.4% (95% confidence interval CI: 1.4–1.9).Data collection regarding, clinical features , gender, age at diagnosis, laterality and type of Duane retraction syndrome, abnormal head posture, amblyopia, Anisometropia (refractive errors), corrected visual acuity, manifest and cycloplegic refraction, alternate cover test, ductions and version ocular movement, fundus examination ,and slit lamp biomicroscopy. Amblyopia is a unilateral or, less commonly, bilateral reduction of best -corrected visual acuity that cannot be attributed directly to the effect of any structural abnormality of the eye or visual pathways. Anisometropia dissimilar refractive errors in the 2 eyes cause the image on one retina to be chronically defocused. Levels of anisometropia that can lead to amblyopia are greater than 1.50 D of hyperopia, 2.00 D of astigmatism, and 3.00 D of myopia. Higher levels are associated with greater risk. 59 males (49.2%) and 61 females (50.8%) presented with age groups, below 2yrs 48 cases (40.0%), 2-5yrs 54 cases (45.0%) and more than 5yrs 18 cases(15.0%). 120 Duane Retraction Syndrome, the unilateral cases were 104 (86.7%) compared to bilateral cases were 16 (13.3%), in unilateral cases, left eye was involved in 90 cases (75.0%) and the right eye 14 cases (11.7%) type I were 108 eyes (90.0%)type II were 7 eyes (5.8%)type III were 3 eyes (2.5%). In bilateral cases type I for right eye &II for left eye was 1 case (0.8%), type I for right eye &III for left eye was 1 case (0.8%), type I for right & left eyes were 14 cases (99.2%). 11 cases with abnormal Head Posture recorded (9.2%). Total number of eyes with higher refractive error (Anisometropia) in Duane retraction syndrome was found in 37 cases, unilateral Duane eyes 29 cases 78.4%and bilateral Duane eyes 8cases 21.6%. Total number of eyes with amblyopia in Duane retraction syndrome were 43 cases ,unilateral Duane eye 33 cases 76.75% (29 of them due to anisometropia and 4 cases due to Duane per se) while in bilateral Duane eye 10cases 23.25% (8 of them due anisometropia and 2 cases due to Duane per se). Each of DRS and anisometropia independently causing amblyopia. But Amblyopia due to Anisometropia found to be more significant association. 2019 artículo científico 1856-4550 https://www.redalyc.org/articulo.oa?id=170263176003 https://www.redalyc.org/journal/1702/170263176003/ https://www.redalyc.org/journal/1702/170263176003/html/ https://www.redalyc.org/journal/1702/170263176003/170263176003.epub https://www.redalyc.org/journal/1702/170263176003/movil en http://www.redalyc.org/revista.oa?id=1702 Revista Latinoamericana de Hipertensión application/pdf Sociedad Latinoamericana de Hipertensión Revista Latinoamericana de Hipertensión (República Bolivariana de Venezuela) Num.3 Vol.14 |
