Abstract

Purpose: To investigate the relationship between optical coherence tomography (OCT) signal strength and visual acuity in cataract patientsand evaluate the effect of cataract on OCT measurements.Materials and Methods: Twenty-one eyes of 18 patients with cataract were included in the study. Patients with other associated ocular pa-thology were excluded. After ophthalmologic examination, mydriasis was induced with 0.5% tropicamide and OCT images were acquired. Thesame assessment was conducted at 1 month after cataract surgery and obtained values were compared with baseline.Results: Mean best corrected visual acuity (BCVA) of the study group was 0.15 ± 0.10 preoperatively and 0.84 ± 0.07 postoperatively andthe difference was statistically signifi cant (p

Özet

Amaç: Kataraktlı hastalarda optik koherens tomografi (OKT) sinyal gücü ve görme keskinliği arasındaki ilişkiyi araştırmak ve kataraktın OKT ölçümleri üzerindeki etkisini değerlendirmek. Materyal-Metod: Çalışmaya 18 hastanın 21 gözü dahil edildi. Katarakt dışında ön segment ya da arka segment patolojisi bulunan ve cerrahiye bağlı komplikasyon gelişen hastalar çalışma dışında bırakıldı. Hastaların oftalmolojik muayenesi yapıldıktan sonra %0.5’lik tropikamid ile pu- pilla dilatasyonu sağlandı ve OKT görüntüleri alınarak kaydedildi. Katarakt cerrahisini takiben aynı uygulama postoperatif 1. ayda tekrarlandı ve elde edilen veriler kaydedilerek cerrahi öncesi verilerle karşılaştırıldı. Bulgular: Çalışmaya dahil edilen hastaların preoperatif en iyi düzeltilmiş görme keskinlikleri (EİDGK) 0.15 ± 0.10 iken postoperatif 0.84 ± 0.07 idi ve aradaki fark istatistiksel olarak anlamlıydı (p
