Diabetic Vitrectomy: A Quick Guide

Vitrectomy refers to a surgical procedure which involves removal of the vitreous gel from the eye. It is a surgical procedure where small ports are created to introduce instruments into the eye and then the surgery performed with the aid of a vitrectomy machine which delivers high speed cutting  to the cutting probe and a light source for visualisation of the inside of the eye and also requires high end microscope fitted with special lens system which gives a wide angle view of the entire retina.

Optical Coherence Tomography: Indications and Uses

Optical Coherence Tomography (OCT) in ophthalmology is an emerging technology and is used to obtain high-resolution cross-sectional images of the nerve layer on the inside of the eye, the retina. It is a non-invasive imaging technology. This technology provides images on the micron scale in real time. The retinal layers can be differentiated, and the thickness of the retina can be measured with optical coherence tomography.

A Simple Guide to Understanding Age-Related Macular Degeneration

Age-related macular degeneration (AMD) is a common chronic disease of the eye which affects millions of people across the world. As the name suggests, it is an eye disorder that affects the macula and hence the central vision. It causes significant disability among people of age 50 and older. It severely threatens the vision and is a leading cause of poor vision or irreversible vision loss in older people.

Treat Cystoid Macular Oedema, for a better vision

Cystoid macular oedema is a painless condition which affects the macula – the central part of the retina (Figure 1.1 and 1.2). This condition occurs when fluid collects in the tissue at the back of the eye, including the area responsible for our central vision. This accumulation of multiple pockets of fluid as cysts in the macular area, is known as cystoid macular oedema.

Diabetic Retinopathy- Can it be Reversed?

The light-sensitive layer of retinal cells converts light into electrical signals which are then sent to the brain where they are turned into the images we see. A brilliant network of tiny blood vessels constantly supplies blood to the retina.
