An Optical Coherence Tomography scan (commonly referred to as an OCT scan) is the latest advancement in imaging technology. This diagnostic technique employs light rays to achieve high resolution pictures of the structural layers of the back of the eye, mainly the retina and the...
The retina is the light-sensitive tissue lining the back of our eye. Light rays are focused onto the retina through our cornea, pupil and lens. The retina converts the light rays into impulses that travel through the optic nerve to our brain, where they are...
Age-related macular degeneration (AMD/ARMD) is a very common problem faced when the central part of the retina called the macula is damaged. It is a leading cause of vision loss after 50 years of age. With AMD the central vision is lost while the peripheral (side) vision...

When high blood sugar levels cause damage to blood vessels in the retina, it is called diabetic retinopathy. This disease has the potential to lead to complete blindness...
Vitreous gel, the clear material that fills the eyeball, is attached to the retina in the back of the eye. As we get older, the vitreous may shrink, pulling away from the retina. Rarely, the vitreous pulls a piece of the retina with it, causing...
