Cataract surgery software

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

A cataract is a blurring of the eye’s natural lens. This lens lies behind the iris and the pupil of the patient’s eye. Cataract surgery is the procedure by which the cloudy lens is removed and replaced with a new IOL (intraocular lens). This new lens is an artificial medical device, which i...

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...

Multi-modal registration of retina images

By R. A. / 08/11/2016 / RSIP Vision Learns / No Comments

Multi-modal registration of retina images is a process by which pictures taken with different modalities and/or at different times are registered. This is done principally when tracking some kind of condition concerning the patient, e.g. the evolution of a disease. One of the things that ophthalm...

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...

Automatic Lesion Detection in Fundus Images

By R. A. / 29/05/2016 / RSIP Vision Learns / No Comments

Diabetic Retinopathy (DR) is an eye disease resulting from long-term diabetic condition. About 80% of long-term diabetic patients suffer from some degree of DR, which accounts for more than 10% of cases of blindness in the USA alone. Early detection of DR and monitoring its progression can spare ...
