Purpose. Congenital retinal macrovessels (CRM) represent rare aberrant vasculature of the retinal vessels that can supply or drain the macula. In this report, the optical coherence tomography angiography features of a congenital retinal macrovessel are discussed. Methods. The history and examination findings are presented alongside swept-source OCT angiography with corresponding B scan and en face OCT imaging. Patients. The case is a 12-year-old female patient with excellent best-corrected visual acuity in both eyes. Results. Swept-source OCT angiography demonstrated considerable loss of the foveal avascular zone at the levels of the superficial and deep capillary plexus. Discussion. In this case there was no detrimental effect on vision despite anatomical loss of the foveal avascular zone.

Multimodal Imaging Analysis in a Case with Congenital Fovea-Involving Retinal Macrovessel and Excellent Visual Acuity

Optical coherence tomography angiography (OCT-A) is a recently established noninvasive technology for evaluation of the retinal and choroidal vasculature. The literature regarding the findings in choroidal nevi is scarce. We report the OCT-A findings associated with two different variants. Subject one had decreased vascular flow signal in the choroidal, choriocapillaris, deep retinal, and superficial retinal layers. Subject two had decreased vascular flow signal in the choroidal, choriocapillaris, and deep retinal layers with a normal vascular flow signal in the superficial retinal layer. To our knowledge, these patterns of decreased vascular flow signals have not been previously reported using OCT-A. This may be due to blockage from the choroidal nevus, true diminished blood flow (ischemia), or other factors.

<div>Optical coherence tomography angiography (OCT A) is an emerging technology to image the vascular system of the eye. At present, there is no consensus regarding the precise indications for OCT A, especially with respect to other widely available imaging modalities such as spectral domain OCT, fluorescein angiography, and indocyanine green angiography.In this special issue, we encourage submissions related to case reports of OCT A in ophthalmic diseases.Potential topics include but are not limited to the following:<ul class="li_special"><li>Retinal vascular diseases</li><li>Choroidal vascular diseases</li><li>Optic nerve diseases</li><li>Ophthalmic oncology</li><li>Anterior segment diseases</li></ul></div>
