Relationship Between COVID‐19 and Retinal Vein Occlusions

Journal of Ophthalmology, Volume 2025, Issue 1, 2025.
The relationship between coronavirus disease 2019 (COVID‐19) infection or vaccination and retinal vein occlusions (RVOs) remains controversial. RVOs include central and branch RVOs. Previous studies have indicated a link between RVOs and COVID‐19. RVOs develop when the retinal blood vessels are clogged by thrombin or lipid deposition.

Retinal Layer and Choroidal Changes in Deep and Scuba Divers: Evidence of Pachychoroid Spectrum‐Like Findings

Journal of Ophthalmology, Volume 2024, Issue 1, 2024.
Purpose: Diving is an intense physical activity under hyperbaric and hyperoxic conditions. The aim of this study is to evaluate the long‐term effects of diving on the thicknesses of retinal layers and retinal anatomy in professional deep and scuba divers.

Pachychoroid neovasculopathy with normal subfoveal choroidal thickness

Modern technologies in ophtalmology, 2021
Pachychoriod neovasculopathy and typical neovascular age-related macular degeneration often look similar, but some differences have been described both genotypically and in the level of cytokine profile, which explains the difference in response to antiangiogenic therapy. It is known that pachychoriod diseases are characterized by choroidal subfoveolar

Relationship between Pachychoroid and Polypoidal Choroidal Vasculopathy

, 2022
Previous clinical studies have suggested that pachychoroid can induce macular neovascularization (MNV) to develop pachychoroid neovasculopathy (PNV) and that PNV can progress to polypoidal choroidal vasculopathy (PCV).

Pachychoroid Neovasculopathy; Findings, Diagnosis, and Treatment

Güncel Retina Dergisi (Current Retina Journal), 2020
Pachychoroid neovasculopathy (PNV) is a novel clinical entity with typical pachychoroid features accompanied by type 1 choroidal neovascularization (CNV). Typical optical coherence tomography finding of the disease is flat irregular pigment epithelial detachments (double layer sign).
