Abstract

Objective: In this study, we aimed to visualize the fetal optic nerve and its sheath in a lateral oblique plane by ultrasound. Methods: This cross-sectional prospective study was conducted at 20–22 weeks of gestation on healthy pregnant women who applied to our perinatology clinic for anomaly screening. Optic nerve sheath diameter (ONSD) measurements were taken from the lateral orbital and the retroorbital planes twice by the same sonographer. Ultrasound durations were recorded. Intraobserver variability was calculated for both techniques. The Bland-Altman analysis was performed for the lateral orbital technique. Results: A total of 45 pregnant women were evaluated in the study. The intraclass correlation coefficient value of the lateral orbital technique was 0.722 (p<0.001), suggesting that the ONSD was measured similarly by the same observer. The ONSD mean measured by the lateral orbital (LO) technique was higher than the ONSD mean measured by the retroorbital (RO) technique (2.10±0.13 vs 1.21±0.13 mm, p<0.001). The ONSD measurement with the LO technique was determined to be more time-effective than the RO technique (129.6±31.3 vs 228.2±32.7 sec, p<0.001). Conclusion: It is demonstrated that by using the lateral orbital technique, the optic nerve and its sheath can be visualized separately without the shadowing artifact of the lens. This technique also takes less time than the RO technique. There is a need for more extensive research on this subject with magnetic resonance imaging (MRI) confirmation.

Özet

Amaç: Bu çalışmada, fetal optik siniri ve kılıfını ultrason ile lateral oblik bir planda görüntülemeyi amaçladık. Yöntem: Bu kesitsel prospektif çalışma, gebeli¤in 20–22. haftasında anomali taraması için perinatoloji klini¤imize baflvuran sağlıklı gebelerle gerçekleştirildi. Optik sinir kılıfı çapı (OSKÇ) ölçümleri, aynı sonografi uzmanı tarafından lateral orbital ve retro-orbital planlarda iki kere yapıldı. Ultrason süreleri kaydedildi. Gözlemci içi değişkenliği her iki teknik için de hesaplandı. Lateral orbital teknik için Bland-Altman analizi gerçekleştirildi. Bulgular: Çalışmada toplam 45 gebe değerlendirildi. Lateral orbital tekniğin sınıf içi korelasyon katsayısı değeri 0.722 idi (p<0.001), bu da OSKÇ’nin aynı gözlemci tarafından benzer flekilde ölçüldüğünü göstermektedir. Lateral orbital (LO) teknikle ölçülen OSKÇ ortalaması, retro-orbital (RO) teknikle ölçülen OSKÇ ortalamasından yüksekti (2.10±0.13 mm’ye karfl› 1.21±0.13 mm, p<0.001). LO teknikle OSKÇ ölçümünün, RO tekniğe kıyasla zaman açısından daha etkin olduğu belirlenmiştir (129.6±31.3 saniyeye karşı 228.2±32.7 saniye, p<0.001). Sonuç: Lateral orbital tekniği kullanarak, lensin gölge artefaktı olmaksızın optik sinirin ve kılıfının ayrı ayrı görüntülenebileceği sonucuna vardık. Bu teknik ayrıca, RO teknikten daha kısa sürmektedir. Manyetik rezonans görüntüleme (MRG) doğrulaması ile bu konuda daha kapsamlı araştırmaya ihtiyaç duyulmaktadır.
