Congenital retinal macrovessels, A "low visual acuity" case report with a 14-year follow-up

Abstract

ABSTRACT. We report a rare case of congenital retinal macrovessel with decreased visual acuity, with a 14-year follow-up. Both the clinical findings and the visual acuity remained unchanged throughout the follow-up period.Key words: Congenital retinal macrovessels -decreased visual acuity -retinal fluorangiographycilioretinal artery.Acta Ophthalmol. Scand. 1999; 77: 474-475 Copyright c Acta Ophthalmol Scand 1999. ISSN 1395-3907A 5-year-old child was seen by us in September 1984. Visual acuity was 20/40 in the right eye and 20/20 in the left. Clinical examination yielded nothing remarkable apart from the right fundus, where the presence of an abnormal vein accompanied by a cilioretinal artery was noticed. There were no signs of haemorhages, exudates, aneurysms or edema.Fluorescein angiography (Fig. 1), showed early filling of the anomalous vein, an anomalous capillary network, and slightly delayed emptying of the vein in the right eye. There were no changes in the permeability of the capillary bed.A magnification of the macular area (Fig. 2), is modified to better show the relation between the foveal region and the anomalous vessels. Fluorangiographic study of the left eye showed a normal retina.We performed a complete clinical examination every year for a 14-year follow-up period; the patient was submitted four times to a fluorangiographic examination.No changes were ever noted in the appearance of the right fundus throughout this time (Fig. 3). The visual acuity in the right eye showed no further decrease.The left eye did not present any alteration during the observation period.

Multimodal imaging of congenital retinal macrovessel with secondary foveal hypoplasia

“…CRM in this patient had two another atypical feature. First, the macrovessel is usually seen to circumscribe around the foveola and rarely pass through its centre 4 10–12. However, the macrovessel passed through the centre of the FAZ in this patient.…”

“…Brown et al first reported seven eyes with CRM having normal vision [ 4 ]. De Crecchio et al followed a case with impaired but stable visual acuity over 14 years [ 6 ].…”

Aberrant congenital macular vessel crossing the fovea: evaluation with optical coherence tomography

“…4 Involvement of the fovea may determine a reduction of visual acuity, stable at longterm follow-up. 2 Visual impairment has been generally attributed without any significant evidence to the mere presence of the macrovessel in the foveal area, rather than to an anomalous development of the neuroretina caused by the abnormal vessel. 2,4,5 Nevertheless, in these reports, no OCT had been performed.…”

“…2 Visual impairment has been generally attributed without any significant evidence to the mere presence of the macrovessel in the foveal area, rather than to an anomalous development of the neuroretina caused by the abnormal vessel. 2,4,5 Nevertheless, in these reports, no OCT had been performed. In this reported case, live microstructural evaluation with OCT has shown non-oedematous foveal thickening and a high-tomedium hyper-reflective area near the vessel that distorted the retinal architecture.…”
