Background: The supply of Cilioretinal artery (CRA) to different layers of retina influences retinal pathologies like diabetic retinopathy. Since the supply of CRA is segmental, Our aim is to analyze the location of CRA) with non center-involving and center-involving diabetic macular edema (DME) and to evaluate the supply of CRA with segments of macular edema based on Early Treatment of Diabetic Retinopathy Study (ETDRS) scale using optical coherence tomography (OCT).Design: Retrospective studyMethods: A retrospective study in which forty-three patients at various stages of diabetic retinopathy with the presence of CRA were identified. Presence and location of CRA was recognized using fundus fluorescein angiography. Classification of DME was based on ETDRS subfields on OCT.Results: Evaluation of 26 men and 17 women of various groups of diabetic retinopathy revealed unilateral CRA in 40 subjects and bilateral CRA in 3 subjects. When CRA supplied the central area, maximum retinal thickness was noted at the temporal quadrant (271.67±164.02 mm) and had non center-involving DME (194.87±121.06 mm), when CRA supplied the lower area, maximum retinal thickness was noted at the superior quadrant (293.64±159.36 mm) and had center-involving DME (395±285.75 mm), and when it supplied the upper area, maximum retinal thickness was noted at the nasal quadrant (293.49±176.18mm) with center-involving DME (292±192.79 mm).Conclusion: The presence of CRA seems to alter the morphology and influences the segment involved in DME. However, further studies with larger sample size are warranted to prove this association. |
