META: High myopia increases retinal detachment risk by 10x. A 6-monthly retina check catches tears early — before vision loss becomes permanent.
If you have high myopia (a prescription stronger than -6.00 diopters), wearing glasses or contacts isn’t enough. Your eyes need extra monitoring that most people don’t know about.
## Why Does High Myopia Affect Your Retina?
High myopia means your eyeball is longer than normal. This elongation stretches the retina — the light-sensitive tissue at the back of your eye — making it thinner and more fragile. People with high myopia have a 10x higher risk of retinal detachment compared to those with normal vision (American Academy of Ophthalmology, 2023).
The problem? Most retinal changes don’t cause symptoms until damage has already occurred. You could have small tears or thinning areas and see perfectly fine — until you don’t.
## What Happens During a 6-Monthly Retina Check?
Your eye doctor uses dilating drops to widen your pupil, then examines your retina with specialized equipment. They’re looking for:
* **Lattice degeneration** — thinning areas that can tear
* **Retinal holes or tears** — early warning signs
* **Peripheral changes** — subtle damage you can’t feel
The exam takes 15-20 minutes and is completely painless. If your doctor finds a small tear, they can often seal it with a simple laser procedure — preventing detachment entirely.
Skipping these checks means problems grow silently. By the time you see flashes, floaters, or a dark curtain across your vision, you may need emergency surgery.
