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

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).

Inversion of Asymmetric Vortex Vein Dilatation in Pachychoroid Spectrum Diseases

Ophthalmology Science
Purpose: Intervortex venous anastomosis is widely recognized as compensating for vortex vein congestion in pachychoroid spectrum diseases. However, determining the blood flow direction within the compensated drainage route is often challenging.

Choroidal neovascularization as a trigger for central serous chorioretinopathy

International Journal of Retina and Vitreous
Background To investigate whether choroidal neovascularization (CNV) may occasionally precipitate central serous chorioretinopathy (CSCR) in patients with pachychoroid features, by analyzing cases where fluorescein angiography (FA)-confirmed leakage ...
