Evalulation of Optical Coherence Tomography Measurements in Peritoneal Dialysis Patients

INTRODUCTION: Optical coherence tomography (OCT) is a non-invasive ocular imaging technique widely used nowadays. There are limited studies focusing on the OCT findings in PD patients. Our aim is to compare retinal changes of peritoneal dialysis (PD) patients with healthy control group by using OCT and investigate the effects of age, gender and duration of PD on these parameters. METHODS: In this cross-sectional study right and left eyes of 32 patients and twenty right and left eyes of ten healthy controls were included. Detailed ophthalmological examinations with central macular thickness (CMT), peripapillary retinal nerve fiber layer (RNFL) thickness, and choroidal thickness (using EDI-OCT) were measured. Macular thickness was measured at five different areas: central,superior, temporal, inferior and nasal. The peripapillary RNFL thickness was analysed in six different areas: temporal, inferotemporal, inferonasal, nasal, superonasal and superotemporal. RESULTS: Sixty-four eyes of 32 patients (18 males, 14 females; aged 20 to 60 years, mean 48.67±12.25 years) with a mean duration of PD of 46.80 months were included. There was a significant difference of macular thickness in the central, temporal, nasal, inferior and superior quadrants between controls and PD patients (p < 0.05). Vitamin D3 supplementation was linked to decreased macular thickness in central, temporal, superior, nasal and inferior quadrants (p

Periton Diyalizi Hastalarında Optik Koherens Tomografi Ölçümlerinin Değerlendirilmesi

GİRİŞ ve AMAÇ: OCT(Optik koherens tomografi), günümüzde yaygın olarak kullanılan non-invaziv bir oküler görüntüleme tekniğidir. PD hastalarinda OCT bulgularinin değerlendirildiği sınırlı sayıda çalışma vardır. Bu calismada amacımız optik koherens tomografi (OKT) ile periton diyalizi (PD) hastalarının retina değişikliklerini sağlıklı kontrol grubu ile karşılaştırmak ve PD'nin yaş, cinsiyet ve süresinin bu parametrelere etkisinin araştırılmasıdir YÖNTEM ve GEREÇLER: Bu kesitsel çalışmaya 32 hastanın sağ ve sol gözü ve 10 sağlıklı kontrolün yirmi sağ ve sol gözü değerlendirildi. Santral maküla kalınlığı (CMT), peripapiller retina sinir lifi tabakası (RSLT) kalınlığı ve koroid kalınlığı (EDI-OCT kullanılarak) ile detaylı oftalmolojik muayeneler ölçüldü. Makula kalınlığı beş farklı alanda ölçüldü: merkezi, üst, temporal, alt ve nazal. Peripapiller RSLT kalınlığı altı farklı alanda (temporal, inferotemporal, inferonasal, nazal, superiornasal ve superiortemporal) analiz edildi. BULGULAR: Ortalama PD süresi 46,80 ay olan 32 hastanın (18 erkek, 14 kadın; 20-60 yaş, ortalama 48,67 ± 12,25 yıl) 64 gözü çalışmaya alındı. Kontroller ve PD hastaları arasında santral, temporal, nazal, inferior ve superior kadranlarda maküla kalınlığı açısından anlamlı farklılık vardı (p
