Glaucoma is a disease of the optic nerve, usually associated with high pressure within the eye. Click Here for more information on the eye disease Glaucoma, its causes, symptoms and treatment.

Conjunctivitis / Pink Eye

Conjunctivitis is a common eye infection where the membrane that lines the eyelids becomes red and irritated. It can be bacterial or viral in cause, or even an allergic response. Click Here for details on Conjunctivitis and Pink Eye.


Cataracts can occur from age 40 and lead to a decrease in vision. They develop slowly and cause clouding in the lens of the eye. For more information on Cataracts and Cataract Surgery, Click Here.

Eyelid Twitching

When the eyelids twitch, it can be a sign of inflammation of the eyelid or a disorder of the eyelid or frontal eye. This can affect people of all ages. To find out more about what causes Eyelid Twitching and what to do about it, Click Here.

Macular Degeneration

Age-related Macular Degeneration (AMD) is a degenerative disorder of the central field of vision. This is the leading cause of vision loss among people over 50 years of age. Click Here for  more about Macular Degeneration.

Retinal Detachment

When the vitreous of the eye moves away from the retina, it can pull the retina and may tear or detach it, causing holes. For more information on Retinal Detachment, Holes and Tears in the Retina, please Click Here.

Dry Eyes

Dry eye syndrome happens when the eye is insufficiently lubricated by tears. It causes eyes to feel tired, irritated and itchy. Click Here for more information about the symptoms and relief of Dry Eye Syndrome.

Diabetic Retinopathy

Otherwise known as diabetic eye disease, is where high blood sugar levels cause damage to the retina and may cause blindness. Diabetics need to undergo regular eye exams to detect and treat this. Click Here to read more about Diabetic Retinopathy.

Floaters & Eye Flashes

Floaters are usually harmless and often age-related, however, it is important to check that floaters and eye flashes are not a sign of anything more serious.


This progressive eye disease results in distorted vision when the cornea bulges and becomes con-shaped.


When the middle layer of the eye, or uvea, becomes inflamed, this can lead to vision loss if the eye tissue becomes weakened or destroyed.

Crossed Eyes (Strabismus)

This condition occurs when the eyes don’t line up while focusing on a single object. It can usually be corrected with early intervention.

Lazy Eye (including Anisoconia)

Also called lazy eye, this occurs when the vision in one eye is reduced because the eye and the brain are not co-ordinating correctly.

Eye Pain

There can be various underlying causes for eye pain and all require investigation by either a doctor or an optometrist to rule out eye diseases.

Diplobia Double Vision (Diplobia)

This happens when the eyes fail to work together to generate a single vision image and could be a symptom of eye diseases or disorder.

Bulging Eyes

Bulging eyes should be checked carefully by a specialist and bulging of one eye, especially in a child, is a very serious sign.

Vision Loss

Blindness and vision loss can be caused by a number of conditions and eye diseases, as well as accidents.

Ocular Hypertension

This is where the pressure in the eye i.e. the intraocular pressure (IOP) is higher than normal and can lead to glaucoma if left untreated.

CMV Retinitis

This is a serious viral eye infection of the retina, often found in people who have weakened immune systems.

Diabetic Macular Oedema

This is a sight-threatening condition, caused when blood vessels in the retina leak into the macula, distorting vision.

Retinal Vascular Occlusions

These can happen to older patients when veins in the retina become blocked, causing problems with the eye.

Ocular Trauma

When anything happens to wound the eye or eye socket, immediate treatment is important to prevent further injury or loss of vision.

Disorders of the Ocular Muscles, Binocular Movement and Accommodation

These involve the six muscles that control eye movement which includes tracking and scanning and movement of the lens to allow focusing.

Disorders of the Optic Nerve & Visual Pathways

These conditions cause disruption to the way visual information is transmitted from the retina to the brain.

Disorders of the Vitreous Body

The vitreous body is the clear, colourless gel that fills the space between the lens and the retina and damage to this may manifest as tiny dark spots in the vision.

Inflammatory Eye Conditions

Inflammation of the eye is often as a result of infection, however, it depends which part of the eye is affected so warrants close investigation.
