Glaucoma is a group of eye conditions that can damage the optic nerve — the vital connection that sends visual information from your eyes to your brain. What makes this disease particularly dangerous is that many people show no early symptoms, earning glaucoma the nickname “the silent thief of sight.” Without timely detection and treatment, glaucoma can lead to irreversible vision loss.
One of the most common forms is open‑angle glaucoma, which develops gradually over many years. In its early stages, there may be no noticeable change in vision, and many people are unaware they have the condition. Vision loss typically starts with the peripheral (side) vision and only becomes noticeable once significant damage has occurred.
Another type, angle‑closure glaucoma, is less common but can occur suddenly and requires urgent medical attention. Symptoms may include severe eye pain, blurred vision, nausea, or seeing halos around lights — and prompt care is essential to prevent rapid vision loss.
Because glaucoma often has no warning signs in its early stages, the most effective way to protect your vision is through regular comprehensive eye exams. These exams typically include measurements of your eye pressure, evaluation of the optic nerve, and tests of your peripheral vision. Early detection allows ophthalmologists to begin treatment that can slow or halt progression, preserving existing vision.
Some people are at higher risk of developing glaucoma and should be especially vigilant with eye health checks. These include individuals over the age of 40, those with a family history of glaucoma, people of African, Asian, or Hispanic heritage, and individuals with conditions like diabetes or high blood pressure.
Though there is no cure for glaucoma, modern treatments — including medicated eye drops, laser procedures, and minimally invasive surgery — can effectively lower eye pressure and protect vision when started early.
At London Ophthalmology, we’re committed to raising awareness of glaucoma and helping patients understand their risk factors, symptoms, and testing options. By prioritising regular eye examinations and early detection, we can work together to safeguard your vision for years to come.
