“…We performed a Spectralis OCT examination, which showed macular thickening without intraretinal fluid accumulation and a subtle foveal contour impairment. By contrast, de Crecchio et al reported a case with decreased vision due to serous retinal detachment of the macula, macular thickening with preserved foveal contour and distorted retinal microarchitecture on OCT [9]. Shah et al reported reduced retinal sensitivity at the macular area using liquid crystal display microperimetry in a case of congenital retinal macrovessel with no sign of macular edema on OCT [10].…”

Congenital retinal macrovessel: atypical presentation using optical coherence tomography

et al. 2010

To describe a congenital retinal macrovessel with macular thickening. This case was investigated using fundus photography, fluorescein angiography, Spectralis optical coherence tomography and a 10-2 visual field test. A 23-year-old man was referred to our clinic with decreased vision in the right eye. Fundus examination of the right eye revealed a congenital retinal macrovessel that originated inferior to the superotemporal branch of the central retinal vein. Using fluorescein angiography, early filling and delayed emptying of the aberrant vein were observed. Spectralis optical coherence tomography demonstrated macular thickening and was supported by a 10-2 visual field test that revealed a relative scotoma corresponding to the same location. At the 18-month follow-up, visual acuity remained stable. Although rare, this case demonstrated that macular thickening can cause decreased visual acuity in the presence of a congenital retinal macrovessel.

“…Normally, high levels of oxygen in the foveal region contribute to the obliteration of the vessels. However, in the case of hypoxia, the proliferation of the vessels may reach the foveola [2]. Brown et al in 1982 formally described the vessel as a "congenital retinal macrovessel."…”

Congenital retinal macrovessels (CRMs) are a rare entity. They are usually unilateral, abnormally large, and aberrant vessels. Although the majority of the patients are asymptomatic, CRMs may affect vision if they are associated with pigmentary changes at the macula, foveolar cysts, central serous retinopathy, macular hemorrhage, or if the macrovessel crosses the fovea.Here, we present the case of a young female who came for a routine ophthalmological evaluation. She was asymptomatic, and the macrovessel was an incidental finding. Visual acuity and slit lamp examination were normal, and dilated fundus evaluation was normal except for CRM in the right eye. Optical coherence tomography angiography imaging helped visualize the depth of the vessel and the analysis of the architecture of the foveal avascular zone.

“…One hypothesis involves the deterioration of the blood-retina barrier of the perifoveal capillary. According to previous reports [ 6 , 7 , 8 , 9 ], macular edema with CRMs may be caused by anomalies of the perifoveal capillary bed around the CRMs, which may have affected the blood-retina barrier of the perifoveal capillary for many years. In our case, there was an abnormal vessel crossing near the central macula, which may have caused deterioration of the blood-retina barrier of the perifoveal capillary and incidentally caused macular edema.…”

We present a case of a congenital retinal macrovessel (CRM) with spontaneous resolution of cystoid macular edema. A 39-year-old woman with sudden decreased vision in her right eye was referred to our clinic and found to have a CRM with macular edema. Her visual acuity was 20/25. A week later, the macular edema disappeared without any treatment, and her visual acuity was 20/15. We performed optical coherence tomography angiography and fluorescein angiography (FA), which revealed no obstruction of retinal flow but a slight disturbance of retinal flow near the central fovea on FA. We encountered a case of spontaneous resolution of macular edema with abnormal vessel crossing near the central macula by a CRM, and multimodal imaging was useful for investigating the pathology of the disease.
