“…Because the majority of sufferers are asymptomatic, congenital retinal macrovessel is usually discovered unexpectedly on physical examinations or in patients with other ophthalmic diseases. In many studies and in normal eyes [6], partial congenital retinal macrovessel can be accompanied by branch retinal artery occlusion [7], retinal deep capillary ischaemia [8], macular retinal cavernous haemangioma [9], retinal arteriolar macroaneurysm [10,11], retinal peripheral telangiectasia [12], vitreous haemorrhage [13], retinal detachment [14], and even venous malformations of the brain [15]. Archer suggested that retinal arteriovenous communications could be divided into three groups [16].…”

Background: The traditional view is that there are no vessels in the foveal avascular zone. The two cases we report show microvessels crossing the foveal avascular zone. Case presentation: A man and a woman, both 25 years old, were both incidentally found on optical coherence tomography angiography (OCTA) to have unilateral aberrant microvessels crossing the foveal avascular zone in their left eyes. Visual acuity was preserved in both patients. The vessel density (VD) and perfusion density (PD) of the eyes with the aberrant microvessels were all higher than those of the contralateral eyes. Nevertheless, measurements of foveal avascular zone (FAZ) dimensions, including its area, perimeter and circularity, were smaller in the left eyes than in the right eyes. No complications were recorded. Conclusions: To date, aberrant microvessels crossing the foveal avascular zone have not been found to impair visual function. OCTA is a non-invasive and quick method that does not require dilation or the use of fluorescein dye. It is a reliable tool for the detection of aberrant microvessels crossing the foveal avascular zone.

“…Congenital retinal macrovessels (CRMs) are aberrant vessels, crossing the horizontal raphe in the macular region and having large tributaries, they are predominantly retinal veins [1,2] originating from the temporal arcade, but could also originate from a retinal artery in 25% of cases or may originate from both arteries and veins. When isolated, CRMs are usually benign and nonvision threatening and most often an incidental finding.…”

Multimodal imaging in a case of a congenital retinal macrovessel associated with a retinal cavernous hemangioma: a case report

et al. 2020

Background: To report the results of multimodal imaging in a case of a congenital retinal macrovessel associated with a retinal cavernous hemangioma. Case presentation: A 52-year-old female patient presented with progressive vision loss in the right eye. BCVA was 8/20 in the right eye and 18/20 in the left eye. Fundus examination of the right eye showed an aberrant retinal macrovessel arising from the inferior temporal major vein. It crossed the foveal area and overstepped to the superior retina. A "brunch of grapes" shaped retinal lesions arised from the macrovessel. Fluorescein angiography showed saccular lesions that filled slowly during the venous phase and became brightly hyperfluorescent saccular caps. SS-OCT of the right eye revealed a highly back-scattering hyper-reflective vessel across the fovea with shadow effect and adhesions between the vitreous and the aberrant macrovessel. It also revealed hypo reflective saccules with hyperreflective borders located in the inner retina corresponding to the cavernous retinal hemangioma. Retinal pigment epithelium undulations and vascular dilations at the level of Haller's layer were observed in both eyes. Indocyanine green angiography revealed chroidal vascular dilatations in both eyes in the late phase. OCT-A showed the aberrant vessel emerging from the inferior temporal vein and splitting the foveal avascular zone horizontally. RCH appeared as small heterogeneous saccular flow areas associated with focal capillary hypo perfusion areas. Asymmetry and distorsion of the foveal avascular zone were also noticed. A diagnosis of retinal macrovessel associated with a retinal cavernous hemangioma was made. Conclusions: Congenital retinal macrovessels and retinal cavernous hemangioma are benign lesions. Their association is rare. Abnormal vascular development is likely to be responsible for their association. Swept source OCT and OCT angiography may be of a great contribution to better evaluate these retinal vascular disorders.

“…Congenital retinal macrovessel (CRM) is defined as a large aberrant blood vessel that traverses through the central macula. It may have large tributaries extending on both sides of the horizontal raphe 1–3. While it was first described in 1869 by Mauthner, the term CRM was coined in 1982 by Brown et al 1.…”

Multimodal imaging of congenital retinal macrovessel with secondary foveal hypoplasia

et al. 2022

Congenital retinal macrovessel (CRM) is defined as a large aberrant blood vessel that traverses through the central macula. It can have large tributaries extending on both sides of the horizontal raphe. The condition is typically asymptomatic. However, visual loss may be reported in case of associated branch retinal artery occlusion, cavernous haemangioma, retinal artery macroaneurysm, retinal deep capillary ischaemia, retinal detachment and vitreous haemorrhage. However, association of CRM and foveal hypoplasia has rarely been reported.We report multimodal imaging in a patient who was presented with visual loss due to foveal hypoplasia secondary to CRM.
