Amaç: Bu çalışmanın amacı; yaş, cinsiyet ve biyometrik parametrelerin spot vision fototarama (SVF) cihazının klinik performansı üzerindeki etkisini değerlendirmektir. Gereç ve Yöntemler: Bu prospektif çalışmada, Ağustos 2019-Şubat 2020 tarihleri arasında oftalmoloji polikliniğinde görülen çocuklar, SVF ve siklopleji sonrası standart otorefraktometre ile refraktif ölçümleri açısından değerlendirildi. Aksiyel uzunluk (AU), ön kamara derinliği (ÖKD) ve kornea eğrilik yarıçapı (KR) değerleri optik biyometri elde edildi. SVF ve otorefraktometre ölçümleri arasındaki sferik ekivalan farkı kullanılarak SVF cihazının klinik performansı ile oküler biyometrik parametreler, yaş ve cinsiyet arasındaki ilişki incelendi. Bulgular: Ortalama yaşı 103,2±32,6 (36-178) ay arasında olan 296 çocuğun (134'ü erkek, 162'si kadın) 592 gözü değerlendirildi. SVF ve sikloplejik otorefraktometre arasında sferik, silindirik ve sferik eşdeğer (SE) değerleri istatistiksel olarak anlamlı farklılık göstermekteydi (p<0,05). AU, ÖKD, AU/KR ve yaş ile sikloplejik otorefraktometre ve SVF arasındaki SE farkı arasında negatif yönlü korelasyon izlendi. Biometrik parametreler içinde en güçlü korelasyonun AU/KR oranı ile (r=-0,670, p=0,000) olduğu bulundu. İki ölçüm yöntemi arasındaki SE farkı ile cinsiyetler arasında istatistiksel olarak herhangi bir anlamlı fark tespit edilmedi (p=0,296). Sonuç: Biyometrik parametreler SVF ölçüm sonuçlarını etkilemektedir. Bu parametreler içinde en etkilisi AU/KR oranıdır. Ayrıca bu biometrik parametrelerin hipermetrop olgulardan, miyop olgulara doğru artması nedeniyle SVF ölçümlerinde hipermetropik olgulardan miyopik olgulara doğru kaydıkça daha güvenilir ölçüm sonuçları elde edilebilmektedir.

Objective: To evaluate the effect of age, gender and biometric parameters on the clinical performance of spot vision screener (SVS). Material and Methods: In this prospective study, children who attended the ophthalmology department between August 2019 and February 2020 were evaluated in terms of refractive measurements with SVS and a standart autorefractometer after cycloplegia. Axial length (AL), anterior chamber depth (ACD) and corneal radius (CR) values were obtained by optical biometry. By using the spherical equivalent difference between SVS and autorefractometer measurements, the relationship between the clinical performance of SVS and ocular biometric parameters, age and gender was examined. Results: A Total 592 eyes of 292 children (134 male, 162 female) with an average age of 103.2±32.6 (36-178) months were evaluated. There were significant difference between SVS and cycloplegic autorefractometer measurements of spherical, cylindrical and spherical equivalents (SE) (p<0.05). A negative correlation was observed between AL, ACD, AU/CR and age with SE difference between cycloplegic autorefractometer and SVS. It was found that the strongest correlation among biometric parameters was with AL/CR (r=-0.670 p=0.000). No statistically significant difference was found between the SE difference between the two measurement methods and genders (p=0.296). Conclusion: Biometric parameters affect SVS measurement results. Most effective of these parameters is AU/CR. In addition because of these biometric parameters increase from hyperopic cases to myopic cases, more reliable measurement results can be obtained as the SVS measurements shift from hyperopic cases to myopic cases.
