Purpose:To determine if there is a stereopsis modification in the X(T) after surgical correction and to know if it is related with final outcome. Methods:This is a prospective, observational study, made in the Strabismus Department of the Fundación "Hospital 'Nuestra Señora de la Luz'". Patients with X(T) were surgically treated from march 01 to august 31, 2001. Making a measurement of stereopsis with Titmus Test, before and after the surgery. This test was made by two physicians. Results:Fourteen patients were included. The initial deviation was of 15-45 DP, averaging 27.5 DP, while the postoperatory average deviation was of 4.7 DP. The follow-up average was 3.3. months (range 1-8 months). Stereopsis previous to the surgery was 40-800 arch seconds, with an average of 236 arch seconds, and after the surgery was 105 arch seconds, with a range of 40-140 arch seconds. Of 14 patient included, 8 (57%) improve the stereopsis; 6 patients (43%) stayed without changes. The surgical success (orthoposition until a deviation of 10 consecutive or residual DP) was present in a 75% of the patients that improve stereopsis and in 20% of the patients, which stayed without changes. Conclusion:Stereopsis in X(T) improved in 57.5% of the patients and 42.5% remain without changes. The improvement in stereopsis and the surgical success are not related.
