Abstract

Amaç: Gebelerde ikinci ve üçüncü trimesterde artırılmış derinlik görüntüleme (Enhanced Depth İmaging –EDİ) Optik Koherens Tomografi (OKT) kullanarak koroid kalınlıgı belirlemek. 

Yöntemler: Bu calısmada 40 gebe ile gebe olmayan (kontrol) 40 sağlıklı kadının her iki gözü EDİ-OKT kullanarak subfoveal, 2 mm nazal, 2 mm temporal koroidal kalınlıkları değerlendirildi. Gebelerden 20’ si 16-24. haftalar arası (ikinci trimester), 20’ si 24-39. haftalar arası (üçüncü trimester) olarak 2 gruba ayrıldi. Yaş ortalaması gebelerde 27.4±5.8, kontrol grubunda 26.9±7.1 olarak hesaplandı. 

Bulgular: Gebelerde koroid kalınlıkları EDİ-OKT ile sağ gözde subfoveal 295.3±51.8μm, 2 mm nazal 242.4±49.2μm (p=0.032); 2 mm temporal 252.3±52.9μm (p=0.001) iken sol göz ölçümlerinde subfoveal 298.4±66.7μm, 2 mm nazal 251.5±54.7μm, 2 mm temporal 263.6±64.3μm (p=0.044) olarak kaydedildi. Kontrol grubunda sağ göz subfoveal 307.8±64.5μm, 2 mm nazal 267.6±54.2μm, 2 mm temporal 292.9±50.9μm, sol göz subfoveal 295.3±71.3μm, 2 mm nazal 269.6±63.7μm, 2 mm temporal 292.0±59.5μm olarak ölçüldü. Gebe grubu ile kontrol grubu koroid kalınlığı karşılaştırıldığında sağ göz 2 mm nazal (p=0.032) ve 2 mm temporal (p=0.001) alanlar ile sol göz 2 mm temporal (p=0.044) alanda kalınlık kontrol grubunda daha yüksek olup istatistiksel olarak anlamlı fark saptanmıştır. Diğer bölgelerde fark bulunmamıştır (p>0.05). 

Sonuç: Bu çalışmada gebe hastalarda benzer yaş grubu ile kıyaslandığında EDİ OKT ile yapılan koroid kalınlık ölçümünün daha ince olduğu tespit edilmiştir.

Choroid thickness measurement in second and third trimester pregnancies by enhanced depth imaging optical coherence tomography

Abstract

Aim: Evaluation of choroid thickness in 2nd and 3rd trimester pregnancies by Enhanced Depth Imaging –EDI Optic Coherence Tomography (OCT). 

Patients and Methods: In this study, the subfoveal, 2 mm nasal, 2 mm temporal choroidal thicknesses of both eyes in 40 pregnant and 40 non-pregnant (control) women were evaluated. The pregnant women were categorized in 2 groups, 20 being 16-24 weeks pregnant (second trimester) and 20 being 24-39 weeks pregnant (third trimester). The average age of the pregnant women and non-pregnant women was calculated as 27.4±5.8 and 26.9±7.1, respectively. 

Results: The choroid thicknesses in the pregnant women were recorded by EDI-OCT as follows; right eye subfoveal 295.3±51.8μm, 2 mm nasal 242.4±49.2μm, 2 mm temporal 252.3±52.9μm and left eye subfoveal 298.4±66.7μm, 2 mm nasal 251.5±54.7μm, 2 mm temporal 263.6±64.3μm. The control group was recorded as follows; right eye subfoveal 307.8±64.5μm, 2 mm nasal 267.6±54.2μm, 2 mm temporal 292.9±50.9μm and left eye subfoveal 295.3±71.3μm, 2 mm nasal 269.6±63.7μm, 2 mm temporal 292.0±59.5μm. The comparison of the choroid thicknesses in the pregnant subjects and the control group shows that the thickness in the 2 mm nasal (p=0.032) and 2 mm temporal (p=0.001) areas of the right eye and 2 mm temporal (p=0.044) area of the left eye is significantly different. No significant difference was observed in the other areas (p>0.05) 

Conclusions: In this study, choroidal thickness measurement with EDI OCT was found to be thinner in pregnant patients compared to similar age group.
