Description

What is Ophthalmology?
 
Ophthalmology is the branch of specialist medicine that is focused on the health of eyes and their surrounding tissues, including muscles, bones, eyelids, and tear production/drainage systems. Your eye is the organ of vision and consists of the cornea (the outer clear layer), the sclera (the white of the eye), the iris (the coloured part), the lens (lies behind the iris) and the retina (the light-sensitive lining at the back of the eye). Your eyes ‘see’ by focusing light that enters the eye onto the retina which sends the image to the brain by the optic nerve.
 
Ophthalmologists are doctors who are trained in the study of eyes. Most will be trained in eye surgery, and may have particular areas of interest or expertise.
Optometrists are not doctors but are trained in testing your vision to assess your need for glasses or contact lenses. Some also test for glaucoma. 

Procedures / Treatments

  • Refractive Error: short-sightedness (myopia), long-sightedness (hyperopia) and astigmatism

  • Cataracts

    Cataracts are the most common age-related occurrence in eyes. The lens becomes thicker and stiffer and appears yellow and cloudy.… More

  • Squints (strabismus)

    A weakness in one or more of the muscles of the eye will cause the eye to turn or move away from the normal focusing position.  This is commonly known as a squint.… More

  • Glaucoma

    Glaucoma is a group of diseases that can damage the eye’s optic nerve and may result in vision loss and blindness. Multiple factors are often important in causing glaucoma, but it is most commonly related to an increase in pressure in the eye.… More

  • Diabetic Retinopathy

    This is a complication of diabetes and is caused by small blood vessel damage within the retina of the eye.  It commonly affects both eyes and may cause permanent loss of vision.  Macular oedema is sometimes also present with diabetic retinopathy.  Macular oedema is when fluid leaks into the retina… More

  • Retinal Detachment

    This is when the retina detaches, meaning it is lifted or separated from its normal position within the eye. An acute retinal detachment requires urgent assessment and appropriate treatment.… More
