The number of patients with arterial hypertension is continually increasing. Hypertension can cause organ complications, called hypertension-mediated organ damage (HMOD). One example is hypertensive retinopathy, in which high blood pressure (BP) damages both the retinal microcirculation and the retinal nerve fiber layer (RNFL). This can result in progressive and painless vision deterioration in some groups of patients. Unlike anywhere else in the human body, the microvasculature of the retina can be observed in vivo, and the progression of changes can be closely monitored. The harmful effect of increased BP on the eye is not only limited to hypertensive retinopathy, but can also lead to an exacerbation of diabetic retinopathy (DR) and to an increase in intraocular pressure (IOP), and it can also trigger the formation of thromboembolic lesions. This review presents an update on the pathogenesis of hypertensive retinopathy and the use of adaptive optics (AO) combined with optical coherence tomography (OCT) to evaluate the retinal microvasculature. The latest progress and directions of research in the field of hypertensive retinopathy are also discussed.

Preeclampsia occurs in hypertensive pregnant women beyond 20 weeks of gestation and is accompanied by proteinuria. Hypertensive retinopathy is the most prevalent sign of preeclampsia, and eclampsia and it needs to be addressed at the earliest opportunity. This study was intended to gauge and assess the ophthalmic artery Doppler indices such as mean enveloped velocity, the pulsatility index (PI), and the resistivity index (RI) in normotensive, preeclamptic, and eclamptic pregnancies with their respective correlations.

This article presents a clinical case of ocular thrombotic microangiopathy of mixed origin (antiphospholipid syndrome, malignant arterial hypertension, multigenic thrombophilia). Multimodal imaging of the fundus provides a detailed assessment of its structures. Pathological changes in the choroid, the "retinal pigment epithelium - Bruch's membrane" complex, and the neurosensory retina, identified using fundus photography, short-wavelength autofluorescence, optical coherence tomography (OCT), and OCT angiography, are described as nonspecific in nature.

Diabetic retinopathy, hypertensive retinopathy, glaucoma, and contrast-related eye diseases are well-recognized conditions resulting from high blood pressure, rising blood glucose, and elevated eye pressure. Later-stage symptoms usually include patches of cotton wool, restricted veins in the optic nerve, and buildup of blood in the optic nerve. Severe consequences include damage of the visual nerve, and retinal artery obstruction, and possible blindness may result from these conditions.
