Glaucoma Myth‑Busting: The Eye Does Not Explode

Myth: "Glaucoma makes the eyeball explode."

Fact: The globe does not rupture from elevated intraocular pressure (IOP). The sclera is a tough, fibrous coat that withstands high pressure.

What Actually Happens

• Chronic IOP elevation → mechanical stress + vascular compromise at the lamina cribrosa → retinal ganglion cell apoptosis → irreversible optic nerve cupping and visual field loss.
• Acute angle‑closure crisis: IOP can spike to 50–70 mmHg → corneal edema, severe pain, nausea — but the eye remains intact.
• In rare cases of buphthalmos (infantile glaucoma), the immature sclera stretches, enlarging the globe — not exploding.

Why the Myth Persists

• Graphic descriptions of "pressure building up" in patient education.
• Confusion with orbital hemorrhage or globe rupture from trauma.

Real Danger

Vision loss is silent, progressive, and irreversible. Early detection (IOP, optic nerve, OCT, visual field) and treatment preserve sight.
