Retinal Detachment Detection

By R. A. / 15/01/2017 / RSIP Vision Learns / No Comments

Retinal detachment occurs when part of the retina detaches itself from the pigmented cell layer of the RPE, depriving itself of blood and nutrition: this condition causes blur and loss of vision. There are 2 types of detachment: either it is caused by fluids, which might be of lacrimal origins, g...

Optical Coherence Tomography Angiography

By R. A. / 10/11/2016 / RSIP Vision Learns / No Comments

Optical coherence tomography angiography (OCTA) is a method which uses OCT to produce high-resolution volumetric images of the vascular tree in the eye. It has the advantage of being a non-invasive procedure. It is quick, and produces high resolution 3-dimensional histological images. With OCTA a...

Stabilization in fluorescein angiography

By R. A. / 29/09/2016 / RSIP Vision Learns / No Comments

One of the most common tests in ophthalmology is fluorescein angiography: fluorescein is injected in the blood and it moves immediately through the blood vessels to the back of the eye. Some drops might also be applied in order to make the pupil dilate. A video clip taken shortly after that, show...

Finding Cysts, Part Five: Final Detection

By Felicity / 08/10/2015 / RSIP Vision Learns / No Comments

Cyst Detection Using Convolutional Neural Networks Graph-search We have been working on automatically detecting the appearance of Cystoid Macular Edema (CME) in Optical Coherence Tomography (OCT) images. CME  is a buildup of fluids in the eye near the macula of the eye that can distort a person&#...
