Common Disorders

Anterior Uveitus is an inflammation of the middle layer of the eye, which includes the iris and adjacent tissue, known as the cilliary body.

Astigmatism occurs when rays of light are irregularly focused because the curvature of the front surface of the eye is irregular. This results in poor vision for both distance and near.

Blepharitis is inflammation of the eyelid.

Cataracts is the clouding of the lens of the eye. Vision becomes blurred or dim because light cannot pass through the clouded lens to the back of the eye.

Colour Vision Deficiency is the inability to distinguish between shades of red & green colour.

Diabetic Retinopathy Diabetes can affect the eye in a number of ways. These usually involve the fine network of blood vessels in the retina.

Dry Eye occurs when your eyes do not produce enough tears or produce tears that do not have the proper chemical composition.


Flashes are usually a sign of electrical activity from the retina or the brain.


Floaters occur when the vitreous humour of the eye detaches from the retina and forms as a compact mass, which is then visible to the patient. It is commonly described as an insect coming in and out of the field of view.


Glaucoma is the name for a group of eye conditions in which the optic nerve is damaged at the point where it leaves the eye.

Long sight (hypermetropia) occurs when rays of light are brought to a focus to an imaginary point behind the retina because the optical power of the eye is too weak, or the eye is too short in length. These condition results in blurred vision when looking at near objects and also blurred distance vision for higher errors.

Macular Degeneration Sometimes the delicate cells of the macula become damaged and stop working. We do not know why this is, although it tends to happen as people get older. This is known as age-related macular degeneration.

Myopia (short-sightedness) occurs when rays of light are brought to a focus in front of the retina because the optical power of the eye is too great, or the eye is too long. This condition results in blurred vision when looking into the distance.

Presbyopia As we get older, the lens of the eye thickens and slowly loses its flexibility leading to a gradual decline in our ability to focus on objects that are close up. This loss of focusing ability is called presbyopia.

Retinal Detachment The retina is usually attached to the inner surface of the eye. If there is a tear or hole in the retina, fluid can get underneath. This weakens the attachment, causing the retina to become detached - rather like wallpaper peeling off a damp wall. When this occurs, the retina cannot compose a clear picture from the incoming rays, so your vision becomes blurred and dim.

Squint (strabismus) arises due to the incorrect balance of the muscles that move the eye, faulty nerve signals to the muscles, and some refractive error (focusing faults). This results in the eye either turning inwards (convergence), turning outwards (divergence) or turn upwards.
