Glaucoma Threatens Millions with Permanent Blindness in India
Glaucoma is a sneaky eye disease that can steal your sight without you even noticing.
It damages the nerve that connects your eyes to your brain, and by the time you realize something is wrong, it might be too late to fix it.
In India, millions of people have glaucoma, but most don't know it because they don't have symptoms early on.
Doctors say it's important to get regular eye check-ups, especially if you're over 40 or have a family history of glaucoma.
There are treatments like eye drops and surgery that can help, but you have to keep using them every day to keep your vision safe.
Doctors are also working to spread awareness and make it easier for people to get checked, especially in places where there aren't many eye doctors.
Glaucoma is a leading cause of blindness in India, affecting 12 million people aged 40-80, with 1.5 million already blind due to the condition.
The disease often progresses without symptoms, leading to late detection and irreversible vision loss.
Risk factors include high eye pressure, age over 40, family history, high refractive errors, diabetes, high blood pressure, eye injuries, and chronic steroid use.
India faces a shortage of eye care infrastructure and trained professionals, with only 21,000 ophthalmologists and 17,000 optometrists serving a vast population.
Treatment involves eye drops, medication, laser treatment, and surgery to lower eye pressure and prevent further nerve damage, but adherence to lifelong treatment is challenging.
