WHAT IS GLAUCOMA TREATMENT?
Glaucoma is a serious condition that involves an elevation in pressure inside the eye caused by a build-up of excess fluid. Always visit a glaucoma specialist rather than a general ophthalmologist.
Glaucoma if left untreated, can destroy the optic nerve, which is the main nerve of the eye. In most cases, it is a painless disease and there are no symptoms other than loss of vision, which can occur so gradually that many people do not realize it is happening. Unfortunately, it cannot be cured, but it can be treated to minimize its damage to the vision. If it is spotted in its early stages, blindness can almost always be prevented.

WHAT ARE DIFFERENT TYPES OF GLAUCOMA?
Cataracts are a part of the ageing process but even people in their 40s and 50s have early cataracts due to various reasons which may not affect eyesight immediately but will develop into a severe cataract later in life. It's better to consult your doctor when you are not able to see the objects clearly.
Different types of glaucoma:
Primary open-angle glaucoma
Primary open-angle glaucoma or chronic glaucoma is the most common type of glaucoma. Its effects occur slowly over time and do not cause you any pain. The drainage of the aqueous fluid from your eye does not happen as well as it should and this causes the pressure to rise.
Acute Angle Closure Glaucoma
Acute glaucoma is much less common. Acute angle closure glaucoma happens when there is a sudden and more complete blockage of the drainage angle, resulting in a sudden build-up of eye pressure. This is because the edge of the iris and the front clear layer of the eyes (cornea) come into contact; which stops the fluid from draining away through the drainage angle (trabecular meshwork).
Ocular hypertension means patients naturally have high eye pressures of above 21mmHg. This is not the same as having glaucoma. A diagnosis of ocular hypertension means your pressure is high but there is no damage to the nerve.
However, some patients with ocular hypertension can develop Glaucoma; patients at risk of developing Glaucoma are treated instead of just being monitored.
Normal tension glaucoma means that your optic nerve is damaged with eye pressure within normal ranges of 8-21mmHg. Your eye pressure will need to be reduced to keep your sight safe and is treated in the same way caused by high eye pressure.
An increase in your eye pressure is caused by another eye condition(s) you have, for example, uveitis. This can lead to damage to the vision and treatment in each case is always aimed at reducing the pressure as well as treating the cause.
Raised eye pressure caused by injury or trauma. Where the injury has damaged the drainage angle or caused internal eye tissues or cells to clog the drainage angle.
A rare type of glaucoma that affects young babies or children, usually caused by an eye or health condition.
Glaucoma – Symptoms
Symptoms can vary depending on the type of glaucoma you have
Open, normal tension, secondary glaucoma
• Your eyesight may feel normal to you
• Your peripheral vision gradually gets worse.
• Tunnel vision where glaucoma has resulted in a loss of your peripheral vision, central vision unaffected
• No pain
• White or colour halos around lights
• Red eye
• Blurred vision
• Tender around the eye(s)
• Nausea or vomiting
• With mild attacks (often in the evening), your vision may seem “misty” with halos and you may have some discomfort in the eye.
This can happen in one or both eyes but it is rare for both eyes to have an attack at the same time. Acute glaucoma is an emergency and needs to be treated quickly if sight is to be saved.
• Unusually large eyes
• Excessive watering of the eyes
• Cloudy or hazy eyes
• Light sensitivity
