In the presence of an aberrant vessel crossing the macular region, visual acuity and ophthalmoscopic and fluoroangiographic findings tend to have remained stable at long-term follow-up.

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.

The authors describe a case of congenital retinal macrovessel with decreased visual acuity. Ophthalmoscopy and fluorescein angiography showed the malformation to be congenital and benign.
