Many eye diseases are caused by genetic factors that have been inherited. If a family history of a vision problem or disease is known, this will aid diagnosis and allow risk assessment for family members. This includes a higher risk of glaucoma, corneal dystrophies, congenital cataract and retinal degenerations. If there is a history of blindness in the family, even if the cause is unknown, it’s valuable to have an eye examination as some conditions are preventable and new treatments are being developed.
If there is a history of blindness in the family, even if the cause is unknown, it’s important to have regular eye examinations as some conditions are preventable and new treatments are constantly being developed.
Known as the ‘sneak thief of sight’, glaucoma is an eye disorder in which the optic nerve suffers damage, which can cause blindness if not treated. It’s often caused by increased pressure of the fluid in the eye. Click here to read more.
An infection of the cornea caused by the herpes simplex virus. Usually, the infection is just in the top layer of the cornea. When deeper layers are involved, there is a possibility of scarring. Treatment usually involves eye drops or medicine, but if scarring occurs, a cornea transplant may be required.
Often called cold sores, these can have a devastating effect on the eye and, if suspected, treatment needs to be commenced as soon as possible. If there is a history of herpes simplex, care must be taken with the use of steroid-containing eye drops and ointments – the use of these must be supervised by your ophthalmologist.
A rare condition only seen with uncontrolled hypertension. It is also associated with a greater risk of retinal vein occlusion. Blurred vision will occur but should be resolved with treatment of the underlying blood pressure.
Keratoconus is a degenerative eye disorder in which the shape of the cornea is distorted and a cone-like bulge develops, causing visual impairment. Essentially, it’s the result of a thinning of the central zone of the cornea.
The lacrimal system produces tears and provides the drainage system of the eye. Problems include dry eyes, inflammation and infection of the glands in the eyelid, eyelid laxity and partial or total blockage of the tear drainage system.
This is the inability to close the eyelids completely. It prevents blinking, which is crucial to cleaning the eye. In serious cases, the eye can suffer abrasions or infections. Treatment ranges from lubricating drops to ointments to surgery.
Also known as hyperopia, this refractive disorder means that it is it’s easier to see objects in the far distance than close up. A typical example is when it’s hard to read a menu in a restaurant or when trying to focus on the print in a newspaper. Hyperopia can be caused by a flat cornea, a short eyeball or a combination of both. Click here to read more.
