What is age-related macular degeneration?

2021-07-23T14:02:16+01:00May 4th, 2021|News|

Age-related macular degeneration (AMD) is caused by the deterioration of the central area of the retina, that sends images via the optic nerve from the eye to the brain. The retina’s central portion, known as the macula, is responsible for central vision in the eye, and it controls our ability to read, drive a car, recognise faces or colours, and […]

Who invented the ophthalmoscope?

2021-07-23T14:01:43+01:00April 16th, 2021|News|

An ophthalmoscope is a device used for examining the interior structures of the eye, including the fundus and retina.

It was invented in 1851 by Hermann Von Helmholtz. He was a professor of anatomy and physiology in Königsberg, Germany.[1]

He wanted to show his students the emission of reflected light from the eye. The first model was constructed of pasteboard, […]

What Is Optical Coherence Tomography (OCT)?

2023-02-14T16:19:55+00:00March 12th, 2021|News|

Optical coherence tomography (commonly referred to as OCT) is a non-invasive imaging test. It uses light waves to take cross-section pictures of the retina, and lens if an anterior segment module is used.


With OCT, an ophthalmologist can see the retina’s different layers. This allows the ophthalmologist to measure their thickness and see anomalies. The equipment will scan the eye without […]
