Summary

The aim of this study is to investigate the macular microvascular network alterations in high myopic eyes using optical coherence tomography angiography.

Description

High myopia is defined as a refractive error equal to or more than -6 D, and/or axial length equal to or more than 25.5 mm².Axial elongation of the globe and subsequent stretch of the retina leads to sight threatening complications.

Quantitative measurements of retinal vasculature in the healthy eye have been reported using several in vivo and in vitro techniques, including confocal microscopy, fluorescein angiography (FA), and swept-source optical coherence tomography (ssOCT) angiography.

The aim of this study is to investigate the macular microvascular network alterations in high myopic eyes using optical coherence tomography angiography.

This cross-sectional prospective study included 75 eyes of 54 patients, they were recruited from the outpatient clinic of ophthalmology department of El-Minia university hospital.They were divided into two groups, group A included 25 normal eyes of 25 patients. Group B included 50 myopic eyes of 30 patients.

All patients subjected to history taking and full ophthalmological examination in addition to axial length measurment before performing OCTA.

Medical and Biotech [MESH] Definitions

An imaging method using LASERS that is used for mapping subsurface structure. When a reflective site in the sample is at the same optical path length (coherence) as the reference mirror, the detector observes interference fringes.

A non-invasive method that uses a CT scanner for capturing images of blood vessels and tissues. A CONTRAST MATERIAL is injected, which helps produce detailed images that aid in diagnosing VASCULAR DISEASES.

Excessive axial myopia associated with complications (especially posterior staphyloma and CHOROIDAL NEOVASCULARIZATION) that can lead to BLINDNESS.

The use of light interaction (scattering, absorption, and fluorescence) with biological tissue to obtain morphologically based information. It includes measuring inherent tissue optical properties such as scattering, absorption, and autofluorescence; or optical properties of exogenous targeted fluorescent molecular probes such as those used in optical MOLECULAR IMAGING, or nontargeted optical CONTRAST AGENTS.

Non-invasive method of vascular imaging and determination of internal anatomy without injection of contrast media or radiation exposure. The technique is used especially in CEREBRAL ANGIOGRAPHY as well as for studies of other vascular structures.
