“… 18 In this patient, the presence of the CRM causes distortion of the FAZ in the affected eye, resulting in interocular asymmetry in FAZ metrics and foveal pit volume. Previous reports of CRM have described patients with small, distorted FAZs 10 or normal FAZs, 8 but no FAZ measurements or fellow eye images were provided for interocular comparison of foveal morphology.…”

“… 1 This phenomenon was first described by Mauthner 2 in 1869, and the condition is most often an incidental finding. CRMs are rare, 3 but they have been observed in conjunction with several other ocular pathologies including branch retinal artery occlusion, 4 cavernous hemangioma, 5 macroaneurysm, 6 retinal detachment, 7 telangiectasias, 8 vitreous hemorrhage, 9 and reduced visual acuity due to obscuration of the fovea. 10 CRMs have previously been examined using fluorescein angiography, 3 , 11 but optical coherence tomography angiography (OCTA) now allows for noninvasive imaging of retinal vasculature and segmentation of the superficial and deep vascular layers.…”

PurposeTo present the case of a 37-year-old female with a foveal macrovessel.ObservationsThe patient had an incidental finding of congenital retinal macrovessel (CRM) in the left eye on optical coherence tomography (OCT). Visual acuity was normal, and slit lamp and dilated fundus examinations were otherwise unremarkable. OCT angiography (OCTA) imaging allowed for visualization of the depth profile of the vessel as well as the foveal avascular zone (FAZ). The FAZ and foveal pit were both smaller in the affected eye compared to the fellow eye.Conclusions and importanceWe describe findings of OCTA imaging in a patient with CRM. Previous reports have relied on examination using fluorescein angiography, which does not provide sufficient axial resolution to discern the different vascular plexuses. This report further characterizes how this rare condition can affect foveal morphology and retinal vasculature.

“…CRMs rarely occurred in conjunction with other retinal vascular pathologies including retinal cavernous hemangiomas [5], macroaneurysms [2] and telangiectasias [6]. In FA in CRMs demonstrates five common findings including [7]: 1.early filling and delayed emptying of the macrovessel 2.tortuosity of the macrovessel with passage of one of the terminal branches across the macular area 3.presence of anastomoses between the aberrant vessels and the major retinal vessels 4.microvascular capillary bed anomalies such as arteriovenous anastomoses, capillary non perfusion and dilated surrounding capillary plexus 5.dye leakage from compromised microvascular bed or blocked fluorescence from the presence of preretinal hemorrhage.…”

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.

“…de Crecchio et al [8] described that 5 of 13 cases complained of visual impairment caused by the CRM in their study. Vitreous hemorrhage [18] , macroaneurysms [19] retinal ischemia [20] , or macular edema [21][22] originating from the CRM have also been reported. Therefore, even if there is no visual discomfort in patients with CRM, regular follow-up in an ophthalmology clinic should be considered to check changes in the macular lesion.…”
