Artificial Intelligence To Detect Papilledema From Ocular Fundus Photographs
News > 30-Apr-2020
April 2020 – Papilledema is optic disc swelling due to high intracranial pressure possibly due to many factors such as cerebral hemorrhage, head trauma, meningitis, hydrocephalus, spinal cord lesions, impairment of cerebral sinus drainage and idiopathic intracranial hypertension (IIH). Irrespective of the cause, visual loss is the feared morbidity of papilledema, and the main mechanism of optic nerve damage is intraneuronal ischemia secondary to axoplasmic flow stasis.
Recently, SERI researchers conducted a study where they trained, validated, and externally tested a deep-learning system (DLS) to classify optic disks as being normal or having papilledema or other abnormalities. The size/scope of the study covered:
- Nearly 16,000 retrospectively collected ocular fundus photographs obtained with pharmacologic pupillary dilation
- Across multiple ethnic populations from 11 countries
- Using various digital cameras
|
In the validation set, the system discriminated
A deep-learning system using fundus photographs with pharmacologically dilated pupils differentiated among optic disks with papilledema, normal disks, and disks with nonpapilledema abnormalities. |
