Understanding Glaucoma: Symptoms, Risks & Treatments

Glaucoma is a leading cause of blindness worldwide, often progressing without noticeable symptoms until significant vision loss occurs. Early detection and appropriate treatment are crucial to preserving sight. At London Ophthalmology Centre (LondonOC), we specialise in advanced glaucoma care, offering personalised treatment plans tailored to each patient's needs.

Types of Glaucoma

Open-Angle Glaucoma: The most common form, where the eye's drainage canals become clogged over time.

Angle-Closure Glaucoma: Occurs when the iris bulges forward to narrow or block the drainage angle formed by the cornea and iris.

Normal-Tension Glaucoma: Optic nerve damage occurs despite normal IOP levels.

Secondary Glaucoma: Results from other conditions like eye injuries or inflammation.

Symptoms to Watch For

Glaucoma often develops slowly and without noticeable symptoms. However, in advanced stages, symptoms may include:

Loss of peripheral vision

Halos around lights

Eye pain

Nausea and vomiting

Sudden loss of vision (in acute cases)

Treatment Options

Treatment aims to lower intraocular pressure to prevent further optic nerve damage. Options include:

Medicated Eye Drops: Reduce eye pressure by improving fluid drainage or decreasing fluid production.

Laser Therapy: Selective Laser Trabeculoplasty (SLT) is a non-invasive procedure that enhances fluid drainage.

Minimally Invasive Glaucoma Surgery (MIGS): Techniques like the XEN Gel Stent and OMNI Surgical System offer safe, effective pressure reduction with quicker recovery times.

Traditional Surgery: In cases where other treatments are ineffective, surgical options may be considered.
