Dry eye syndrome is caused by a chronic lack of sufficient lubrication and moisture on the surface of the eye.
If your eyes:
- become red
- feel gritty
- feel itchy
- feel burning and painful or
- if you have a feeling that something is in your eye or
- if you experience an excessive tear production as a reflex to dryness
these are regular symptoms for dry eye.
Patients with the most severe disease are at increased risk of developing corneal infection, scarring or ulceration. These conditions can cause permanent vision loss, although this is rare.
The causes of the dry eye syndrome are many:
- Weather conditions such as dry air, dust, sand which are typical for Cyprus and countries around the Mediterranean
- It becomes a natural consequence of the aging process
- Taking some medicines can cause this
- Insufficient blinking
- Air conditioning
- Long term use of contact lenses
- The Sjogren’s syndrome (a triad of dry eyes, dry mouth and rheumatoid arthritis or lupus)
If you have been diagnosed by a doctor with dry eye you should go to a further check-up because this can be a symptom of systemic diseases such as lupus, rheumatoid arthritis, ocular rosacea and more.
Glaucoma is a term used to describe a group of diseases that damage the eye’s optic nerve and it is normally associated with increased fluid pressure in the eye.
It starts with people losing their side (peripheral) vision and it’s like they look into a tunnel.
If not treated on time, it will cause severe loss of eye vision or even blindness.
It has no symptoms so the patient can only find out if he has Glaucoma only with a special eye test.
Unfortunately this eye disease cannot be treated. So if the patient has lost part of his vision, this cannot be restored.
Keratoconus is a condition that results from an irregularly shaped cornea, which prevents light from focusing correctly on the retina.
These structural changes within the cornea cause it to thin and change to a more conical shape than the more normal gradual curve, causing blurred vision and sensitivity to bright lights.
Common symptoms are:
- Multiple images
- Starbursts around lights
- Blurred vision
With the use of corrective lenses fitted by a specialist most of the times this distortion of vision can be restored in order for the patient to have a normal life. There are though a few severe cases where keratoconus can only be treated with surgery.
Macular degeneration is a disease which attacks the macula of the eye, a small spot near the center of the retina where our sharpest central vision occurs.
It is a progressive eye condition and it is also considered to be a leading cause of vision loss among people age 50 and older.
The early and intermediate stage of AMD usually starts without symptoms, so the only way to find out if you have AMD or not is to go to an optometrist or ophthalmologist to take a special eye exam. But common symptoms are:
- dark areas or distortion in your central vision
- rarely, permanent loss of your central vision
There are two types of AMD:
- Dry or atrophic macular degeneration and
- Wet or exudative macular degeneration.
This type is caused by aging and thinning of the tissues of the macula and usually vision loss is gradual.
If not diagnosed immediately by an optometrist, the dry form can change into wet or exudative macular degeneration, which is more dangerous.
This format of macular degeneration is more dangerous than the dry or atrophic macular degeneration and if not diagnosed and treated on time, the chance you have of preserving some or much of your central vision is limited.
