Distinguishing retinal angiomatous proliferation from polypoidal choroidal vasculopathy with a deep neural network based on optical coherence tomography

Scientific Reports, 2021
This cross-sectional study aimed to build a deep learning model for detecting neovascular age-related macular degeneration (AMD) and to distinguish retinal angiomatous proliferation (RAP) from polypoidal choroidal vasculopathy (PCV) using a convolutional

Polypoidal choroidal vasculopathy [PDF]

British Journal of Ophthalmology, 2007
Polypoidal choroidal vasculopathy (PCV) has been recognised for almost two decades. In 1990, Yannuzzi and colleagues first described idiopathic polypoidal choroidal vasculopathy (IPCV) macular disorder—a choroidal vasculopathy that causes haemorrhagic and exudative macular degeneration—in 11 patients.1 The patients had peculiar polypoidal subretinal ...

Advances in Deep Learning Applications for Choroidal Images Analysis: A Narrative Review

IET Image Processing, Volume 20, Issue 1, January/December 2026.
Clinical detection and evaluation of the choroid primarily rely on imaging and subsequent image analysis. The application of artificial intelligence (AI), particularly deep learning (DL), in the analysis of choroidal images shows significant potential for improving accuracy and efficiency.

Intrapapillary Hemorrhage With Adjacent Peripapillary Subretinal Hemorrhage and Reduced Blood Flow in the Optic Papillary Region Observed on Laser Speckle Flowgraphy

Case Reports in Ophthalmological Medicine, Volume 2026, Issue 1, 2026.
Intrapapillary hemorrhage with adjacent peripapillary subretinal hemorrhage (IHAPSH), commonly observed in myopic eyes with tilted optic discs, typically resolves without treatment. Although IHAPSH cases have been rarely reported, no prior studies have assessed laser speckle flowgraphy (LSFG) in this context.
