ÖZET
 Amaç: Simetrik ve asimetrik cerrahi yapılan primer ekzotropya hastalarında cerrahi sonuçları değerlendirmektir. Gereç ve Yöntemler: Temmuz 2001-Ocak 2016 tarihleri arasında kliniğimiz Şaşılık ve Nörooftalmoloji Biriminde iki taraflı dış rektus geriletmesi (simetrik cerrahi) ve tek taraflı dış rektus geriletmesi ile iç rektus kısaltması (asimetrik cerrahi) yapılan primer ekzotropya hastalarının kayıtları incelendi. Simetrik (Grup 1) ve asimetrik (Grup 2) cerrahi hastalarındaki cerrahi sonuçlar ve etkileyen faktörler karşılaştırıldı. Bulgular: Grup 1 hastalarının 15 (%45)'i kadın, 18 (%55)'i erkek; Grup 2 hastalarının 25 (%56)'i kadın, 20 (%44)'si erkek idi. Cerrahi yaşı Grup 1 hastalarında 22,45±15,99 (5-63) yıl, Grup 2 hastalarında 19,58±8,61 (4-45) yıl bulundu. Grup 2 hastalarında anizometropi oranları, refraksiyon değerleri ve cerrahi öncesi kayma açıları daha yüksek, binoküler görme oranları daha düşük saptandı. İki grubun cerrahi miktarları ve cerrahi sonrası kayma açıları arasında istatistiksel anlamda fark bulunmadı. Cerrahi başarı Grup 1 hastalarının 30 (%90,9)'unda elde edilirken, daha büyük kayma açısına sahip Grup 2 hastalarının 36 (%80)'sında elde edildi. İki gruptaki binoküler görme artışı cerrahi öncesine göre anlamlı bulundu. Sonuç: Ekzotopya hastalarında klinik özelliklerine göre seçilecek simetrik veya asimetrik cerrahi ile başarılı sonuçlar alınmaktadır.

Anahtar Kelimeler: Asimetrik cerrahi; ekzotropya; simetrik cerrahi
ABSTRACT
 Objective: To evaluate surgical outcomes in patients with primary exotropia who had symmetric and asymmetric surgery. Material and Methods: The records of the patients with primary exotropia who underwent bilateral lateral rectus recession (symmetric surgery) and unilateral lateral rectus recession with medial rectus resection (asymmetric surgery) were evaluated at Strabismus and Neuro-ophthalmology Department of our clinic between July 2001-January 2016. Surgical outcomes and influencing factors were compared in patients of symmetric (Group 1) and asymmetric (Group 2) surgical groups. Results: Fifteen (45%) patients of Group 1 were women and 18 (55%) were men, whereas 25 (56%) patients in Group 2 were women and 20 (44%) were men. Age at surgery was 22.45±15.99 (5-63) years in Group 1 patients, and 19.58±8.61 (4-45) years in Group 2 patients. The rate of anisometropia, refraction values and preoperative deviation angles were higher, the rate of binocular vision were lower in Group 2 cases. No significant difference was detected between the amount of surgery and postoperative deviation angles in both groups. Surgical success was achieved in 30 (90.9%) patients of Group 1, while in 36 (80%) patients of Group 2 cases which had greater deviation angle. The increase in binocular vision was significant compared to preoperative in both groups. Conclusion: Successful outcomes can be achieved when symmetric or asymmetric surgical technique is selected according to the clinical features of the patients.
