“…It has been hypothesised that the retinal vessels around the fovea may play a role in the foveal development. Anomalous retinal vessel inside the FAZ may hamper its proper development, leading to foveal hypoplasia 9…”

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.

“…C ongenital retinal macrovessel (CRM) is defined as an abnormal large retinal vessel that encircles the foveal avascular zone (FAZ) [1] . Since the first description of a large aberrant vessel crossing the macula by Mauthner [2] in 1868, there have been several case reports about CRM [3][4][5][6][7][8][9][10] . And recently, Pichi et al [1] reported clinical manifestations and multimodal retinal imaging of 49 eyes with CRM.…”

“…FH can manifest as an isolated condition or in conjunction with other clinical presentations, such as albinism, aniridia, retinopathy of prematurity, incontinentia pigmenti, achromatopsia, optic nerve hypoplasia, familial exudative vitreoretinopathy, congenital retinal macrovessels, and Stickler syndrome [1][2][3][4]. The clinical profile of FH often encompasses nystagmus and variable visual acuity.…”

This study aimed to evaluate foveal avascular zone (FAZ) features and macular flow density (FD) in various retinal layers in a cohort of patients with foveal hypoplasia (FH) using optical coherence tomography angiography (OCTA), in order to characterize microvascular abnormalities and explore their potential clinical significance. FAZ parameters and FD, as well as retinal thickness and volume values were analyzed and compared between patients with FH and an age- and gender-matched control cohort. Correlations between disease severity and visual acuity (VA), as well as between disease severity and FAZ features were evaluated. A total of 19 eyes with FH and 19 control eyes were included. The study group showed significantly higher FD values in the foveal sectors of the superficial and deep capillary plexus compared to controls. FAZ area, perimeter, and acircularity index (ACI) were noticeably altered in eyes with FH; however, they did not correlate with disease severity. Visual acuity was negatively correlated with disease severity. The results of this study provide evidence of altered microvasculature architecture specifically in the foveal sectors of patients with FH. The higher FD values in the foveal sectors of FH patients suggest a potential compensatory response of the retinal microvasculature. FAZ parameters and FD values of the foveal sectors could be used as part of an OCTA-based grading system in FH patients.
