The eyes are probably the most sensitive organs of the body. They are moist and constantly exposed to the environment, which makes them easy targets for foreign particles to attack. Allergic reactions in the eye are called allergic conjunctivitis. Let us explore allergic conjunctivitis in more detail. Allergic reactions are the body’s way of reacting [...]

Eye Strain
Since childhood, our mothers have told us to look after our eyes since they are very precious. One way of doing this is to keep eye strain to a minimum, which is quite difficult since we use computers and cell phones almost constantly. Even though the eye is small, it provides a very important function [...]

Retinal detachment
The retina is the light-sensitive layer of tissue that lines the inside of the eye and sends visual messages through the optic nerve to the brain. When the retina detaches, it is lifted or pulled from its normal position. The retina receives oxygen and nutrients from the underlying choroid (vascular layer) of the eye. When [...]

Orthokeratology
Orthokeratology or Ortho-K is a non-surgical process which reshapes (flattens by compression) the cornea of the eye using contact lenses to reduce refractive errors (nearsightedness and astigmatism). Ortho-K uses reverse geometry contact lenses. Flattening the cornea reduces the focusing power of the eye. Since the amount of corneal flattening can be accurately controlled, it is possible [...]
Glaucoma – leading cause of irreversable blindness
Glaucoma is the world’s leading cause of irreversible blindness, yet few sufferers are aware that they have the disease. What makes this condition difficult to detect is the lack of any early warning signs or symptoms. Once the first visible symptoms occur, there is already serious damage done to the eyes’ optic nerves. Glaucoma definition [...]
Keratoconus
Keratoconus is a disorder of the eyes affecting the cornea. The cornea of the eye is the clear transparent, dome shaped tissue that covers the iris and the pupil. The cornea shields the eye from germs, dust and other harmful matter. It also acts as the eye’s outer lens. Much like a window, the cornea [...]
