“…In highly myopic eyes with PICC, OCTA has revealed a significant reduction in vessel density not only at the choroidal level but also at the level of the RPC. Based on B-scans of OCTA, Kim et al observed a preserved choriocapillary signal against Bruch’s membrane, which completely vanished within the hyperreflective cavity ( 56 ). Another notable vascular abnormality involves the TI vein, which has been described in several cases as either submerging into the intrachoroidal cavitation (ICC) or covering the sinkhole of the PICC ( 48 , 57 ).…”

Highly myopic optic nerve head (ONH) abnormalities encompass a series of complications resulting from the stretching of papillary and peripapillary structures during significant axial elongation. The morphological changes in the ONH typically initiate with disk tilting or rotation, progressing to PHOMS and PPA. Tissue defects in each layer manifest as focal lamina cribrosa defects (FLDs), peripapillary intrachoroidal cavitations (PICCs), and acquired pits of the optic nerve (APON). Anterior vitreous/vascular traction and posterior scleral protrusion may lead to prelaminar schisis as well as paravascular cysts and holes, which can potentially develop into retinoschisis. Traditional color fundus photography (CFP) is often insufficient for visualizing most of these lesions, yet their description and quantification benefit significantly from the advancements in optical coherence tomography (OCT) and OCT angiography (OCTA), complemented by fundus autofluorescence (FAF), indocyanine green angiography (ICGA), and three-dimensional imaging. The effective diagnosis and classification of ONH abnormalities heavily rely on a comprehensive understanding of their multimodal imaging features, as outlined in this review. These findings provide valuable insights into optic neuropathy in high myopia, establishing a solid foundation for future endeavors in disease monitoring and treatment guidance.

Introduction. Choroidal macrovessel (CM) is a rare anatomical feature most often detected incidentally. Recent studies suggest an arterial origin of CM, with the majority of authors considering it to be an enlarged short posterior ciliary artery. The literature describes both variants of CM not associated with retinal changes and those complicated by exudative manifestations. Purpose. This study aims to describe two clinical cases of choroidal macrovessel and conduct a differential diagnosis based on literature data with clinically similar conditions. Material and methods. Patients underwent a standard ophthalmologic examination, as well as optical coherence tomography, optical coherence tomography angiography (protocols 10 and 20 degrees), and multispectral laser scanning. Results. We present descriptions of two clinical cases: CM in a patient with choroidal folds and a prominent CM with accompanying subretinal fluid. In both cases, CMs were incidental findings not associated with reduced visual acuity. In the second clinical example, we demonstrate the presence of subretinal fluid in a patient with CM, with no negative progression after one year of observation. For differential diagnosis, an analysis of conditions with similar clinical manifestations was conducted based on literature data. Conclusion. The presented clinical cases illustrate the diversity of CM manifestations. In most cases, the pathology is not associated with retinal structural abnormalities; however, it can cause retinal changes in some patients. Due to its rarity, CM can be considered a poorly studied anatomical feature, warranting dynamic observation upon detection.
