As glaucoma is often detected by these characteristic optic disc changes, having an understanding of how to assess the optic disc for changes seen in glaucoma is essential. Part 1 in this series ...

Segmentation of disc and cup in glaucoma images. U-Net with Canny edge detection and dilation for visualization of cup to disk ratio (CDR) in fundus images.

Aim: To study whether reversal of optic disc cupping after intraocular pressure (IOP) reduction is related to risk of glaucoma progression. Methods: In this prospective follow-up study, where 51 ...

across all metrics for combined disc and macula images. “This finding suggests that vascular information provided by OCTA plays a crucial role in early glaucoma detection, particularly in cases ...

Excavation was the most common feature of progressive disc changes. Excavation describes an undermining of the optic disc as the cup expands from loss of neural tissue and the laminar connective ...

Purpose: To determine the clinical features of optic disc progression in patients with ocular hypertension and early glaucoma. Patients: A total of 336 eyes of 168 patients with ocular ...

in generating optic disc cupping. One of the outstanding problems in understanding optic nerve head dysfunction in glaucoma has been the elucidation of the pathways that could integrate the ...

Other differential diagnoses which were kept in mind were large optic disc secondary to glaucoma, morning glory disc anomaly and even peripapillary staphyloma. The patient had no systemic medical ...

disc ratio (CDR). In selected subjects, a threshold visual field examination was performed. Glaucoma was diagnosed on the basis of statistical abnormality of the vertical CDR combined with an abnormal ...

The cup and disc are placed in the middle, and the CDR ratio is set to 1:1. Dataset-1 consists of 210 glaucoma samples (69 samples from the BEH dataset and 141 samples from the ACRIMA dataset) and 369 ...
