Refraktif akomodatif ezotropya hastalarında stereopsis düzeyi ve ilişkili faktörler

Amaç: Refraktif akomodatif ezotropyası olan hastalarda stereopsis düzeyini değerlendirmek ve stereopsise etki eden faktörleri ortaya çıkarmak.Yöntemler: Ocak 2010- Haziran 2020 yılları arasındaki refraktif akomodatif ezotropya ile takip edilen hastaların kayıtları retrospektif olarak gözden geçirildi. Yaş, sikloplejik kırma kusuru, iki göz arasındaki kırma kusuru farkı, yakın ve uzak fiksasyondaki kayma açısı, füzyon kabiliyeti ve stereo keskinlik değerlendirildi. Hastalar stereopsis düzeyine göre 2 gruba ayrıldı: iyi stereopsis (40-100 sn ark), zayıf stereopsis (>100 sn ark).Bulgular: Toplam 62 hasta dahil edildi. Bunlardan 14 hasta (22,5%) iyi stereopsis grubundaydı. İlk vizitteki yaş ortalaması 5,35 idi (3-11 yaş aralığı). İlk vizitteki ortalama yaş, iki göz arasındaki kırma kusuru farkı, son vizitteki gözlükle kayma açısı, iyi stereopsis grubunda, zayıf stereopsis grubuna göre düşük bulundu. Ancak, yalnızca uzak fiksasyondaki ortalama kayma açısındaki düşüklük istatistiksel olarak anlamlı olarak bulundu. (p=0,038)Sonuç: İyi stereopsise sahip olan refraktif akomodatif ezotropya hastalarında uzak fiksasyondaki artık kayma miktarı anlamlı derecede düşüktür.

Evaluation of stereopsis level and it’s associated factors in patients with refractive accommodative esotropia

Aim: To investigate the level of stereopsis in patients with refractive accommodative esotropia and to find out associated factors with good stereopsis.Methods: The hospital records of patients with refractive accommodative esotropia from January 2010 to June 2020 were retrospectively reviewed. Age, cycloplegic refractive error, the difference of refractive error between two eyes, angle of deviation at near and distance fixation, fusional ability and stereoacuity were evaluated. Patients were divided into two groups according to the stereopsis level: good stereopsis (40-100 arcsec) and poor stereopsis (>100 arcsec). Results: A total of 62 patients were inclueded. Of them, 14 patients (22.5 %) were in good stereopsis group. The mean age was 5.35 years (range 3-11 years). The mean age at first visit, refractive differences between eyes and final deviation angle with spectacle were smaller in the good stereopsis group than in the poor stereopsis group. But, only the mean deviation angle at distance was found significant statistically between two groups. (p=0.038)Conclusion: Residual esodeviation at distance fixation was significantly lower in patients with refractive accommodative esotropia who have good stereopsis.
