Abstract

In our study we want to evaluate the ocular blood flow and cho- roidal thickness of patients with chronic renal failure (CRF) who underwent regular dialysis and healthy individuals. Twenty-one patients (42 eyes) with diagnosis of CRF who regularly hemo- dialized and 21 healthy volunteers (42 eyes) as a control group were included in the study. Ocular blood flow was assessed with Doppler US and choroidal thickness was measured with optical coherence tomography (OCT). Ophthalmic artery (OA) mean ma- ximum systolic velocity (Vmax) values were 56.23±19.22 cm/sec in the left, and 61.80±18.24 cm/sec in the right eyes, in patients with CRF, and, 40.04±7.90 cm/sec in left, and 40.61±8.55 cm/sec in the right eyes in the control group, respectively. The resistivity indices (RIs) were 0.77±0.05 in right, and 0.77±0.03 in the left eyes in OA, and in RIs were 0.65±0.03 in right, and 0.66±0.02. in the left eyes in the control group, respectively. Mean choroidal thickness was 165.36±51.29 μm in CRF, and 291.79±51.65 μm in the control groups. In patients with CRF who regularly hemodiali- zed; especially in OA, flow rate and RI values were calculated hig- her than those of the control group, and there was a significant choroidal thinning compared to healthy individuals.

Özet

Çalışmamızda düzenli diyalize giren kronik böbrek yetmezliği (KBY) olan hastalar ile sağlıklı bireylerin oküler kan akımının ve koroid kalınlığının değerlendirilmesi amaçlanmıştır. Çalışmaya KBY tanısı olan ve düzenli olarak hemodiyalize giren 21 hasta (42 göz) ve 21 sağlıklı gönüllü birey (42 göz) kontrol grubu olarak da- hil edildi. Oküler kan akımı doppler ultrasonografi (US) ile değer- lendirildi. Koroid kalınlıkları ise optik koherens tomografi (OKT) ile ölçüldü. Oftalmik arter (OA) ortalama maksimum sistolik hız (Vmax) değerleri KBY olan hasta grubunda sol gözde 56,23±19,22 cm/sn; sağ gözde 61,80±18,24 cm/sn; kontrol grubunda sol göz- de 40,04±7,90 cm/sn sağ gözde 40,61±8,55 cm/sn olarak öl- çülmüştür. OA’lerdeki rezistivite indeks (RI) değerleri sağ gözde 0,77±0,05 sol gözde 0,77±0,03 olarak hesaplanmışken kontrol grubunda bu değerler sağ gözde 0,65±0,03 sol gözde 0,66±0,02 olarak hesaplanmıştır. Koroid kalınlıkları KBY olan hasta grubun- da ortalama 165,36±51,29 μm, kontrol grubunda 291,79±51,65 μm olarak ölçülmüştür. KBY olan ve düzenli diyalize giren hasta- larda özellikle OA’de belirgin olmak üzere akım hızı ve RI değerleri yüksek olarak hesaplanmış ve bununla birlikte koroid kalınlıkla- rında sağlıklı bireylere göre belirgin incelme görülmüştür.
