1. Introduction
The cilioretinal artery occlusion is very rare and accounts for 5% of retinal artery occlusions [1]. Optical coherence tomography angiography (OCT angiography) is a new imaging technology that allows for fast, noninvasive assessment of microvascular perfusion across the macular region, offering the potential to perform quantitative assessment. OCT angiography has the capability to segment each layer of the retinal microvasculature in normal and pathological eyes without dye injection [2]. Herein, we aimed to characterize the appearance of the peri- and parafoveal macular microvasculature in a visually asymptomatic young patient with the cilioretinal artery occlusion in chronic phase using OCT-A and to compare different imaging modalities.
2. Case Report
A 37-year-old man without any history of ocular and systemic pathology presented with painless visual decrease in his right eye for 10 days. He had suffered from multiple episodes of amaurosis fugax for 30 days. Clinical examination, spectral-domain OCT (SD-OCT), OCT angiography (XR Avanti, software version 2015.1.1.98, Optovue Inc., Fremont, California, USA), fluorescein angiography, and color fundus photography, as well as systemic and laboratory assessments, were used to document findings in the patient with cilioretinal artery occlusion combined with central retinal vein occlusion. The patient presented in this report has given informed consent for this publication.
At the first visit, his best-corrected visual acuity (BCVA) was 20/60 in the right eye (RE) and 20/20 in the left eye (LE). Fundus examination of the RE demonstrated a whitening of the retina along the distribution of the cilioretinal artery. The retinal veins were mildly dilated and tortuous and accompanied by adjacent retinal haemorrhages (Figure 1(A)). Fluorescein angiography demonstrated delayed filling and emptying of this artery (Figure 1(B)). A SD-OCT examination...
