Özet

Aim: To evaluate the relationship between binocularity and optokinetic nystagmus asymmetry (OKN) in patients with infantile esotropia. Methods: The study design was prospective and cross-sectional. Ten patients who underwent surgery for infantile esotropia between 1982 and 2010 in the Department of Ophthalmology of the İstanbul University, İstanbul Faculty of Medicine were included in the study. The patients underwent complete ophthalmic examination including spherical equivalent, deviation angle, simultaneous perception (SP) and OKN stimulation. The patients were grouped according to the SP grades. The ratio of temporo-nasal (TN) OKN frequency to nasotemporal (NT) OKN frequency was compared between the SP-positive and negative-groups. Results: In the SP-negative group, the mean number of TN and NT amplitudes and the ratio of number of TN/NT amplitudes were 26.20±9.31, 11.40±5.59, and 2.42±0.77, respectively. In the SPpositive group, the mean number of TN and NT amplitudes and the ratio of number of TN/NT amplitudes were 29.40±10.64, 17.60±8.08, and 1.82±0.57, respectively. When both groups were compared, the detected p values were 0.91, 0.29 and 0.24, respectively. Conclusions: We detected lower OKN asymmetry in the low-grade binocularity group compared to that in binocularity-negative group. We think that these findings did not reach a statistically significant level due to the limited number of patients enrolled in our study.

Abstract

Amaç: İnfantil ezotropyalı hastalarda optokinetik nistagmus (OKN) asimetrisi ile binokülarite arasındaki ilişkiyi incelemektir. Yöntemler: Prospektif, kesitsel bir çalışmadır. Çalışmaya 1982 ile 2010 yılları arasında infantil ezotropya nedeniyle İstanbul Üniversitesi İstanbul Tıp Fakültesi’nde cerrahi uygulanan 10 hasta çalışmaya dahil edildi. Hastalara sferik eş değer, kayma açısı, simultane persepsiyon (SP) testi ve OKN uyarımı testini içeren tam bir göz muayenesi yapıldı. Hastalar SP düzeyine göre gruplandırıldı. SP saptanan grup ile saptanmayan grup arasında temporo-nazal (TN) OKN frekansının, nazo-temporal (NT) OKN frekansına oranı karşılaştırıldı. Bulgular: SP olmayan grupta ortalama TN genlik sayısı 26,20±9,31, NT genlik sayısı 11,40±5,59, TN/NT oranı 2,42±0,77 saptandı. SP olan grupta ortalama TN genlik sayısı 29,40±10,64, NT genlik sayısı 17,60±8,08, TN/NT oranı 1,82±0,57 saptandı. Her iki grup arasında TN genlik sayısı, NT genlik sayısı ve TN/NT oranı karşılaştırıldığında p değerleri sırası ile 0,91, 0,29 ve 0,24 olarak bulundu. Sonuç: Düşük derece binokülarite olan grupta binokülarite olmayan gruba göre daha az OKN asimetrisi saptadık. Çalışmamızın hasta sayısının azlığı ile ilgili sınırlamalarından dolayı bu bulguların istatistiksel olarak anlamlı seviyeye ulaşmadığını düşünmekteyiz.
