Glaucoma is an eye disease that causes changes to the peripheral vision due to damage to the optic nerve.
The optic nerve is the cable that connects the eye to the brain.
Risk factors for glaucoma include age, genetics (it runs in families), high pressure in the eye, history of eye injury, thin corneas and other eye anatomy differences, and some systemic conditions like diabetes, hypertension, sleep apnea, and migraines.
There are several different types of glaucoma:
Open angle glaucoma
Angle closure glaucoma
Normal tension glaucoma
Pigmentary glaucoma
Neovascular glaucoma
It is the standard of care that patients who have glaucoma or are a glaucoma suspect have at least one dilated eye exam per year.
Additionally, your optometrist may recommend more testing including:
Intraocular pressure: the pressure in your eye
Visual field testing: the sensitivity of your peripheral vision
Retinal photography: pictures of the optic nerve
Optic nerve OCT: a scan to look for damage to the optic nerve
Pachymetry: a measurement of the thickness of your cornea
Gonioscopy: an evaluation of the drainage system of the eye
The treatment options for glaucoma include:
Eye drops to lower the pressure in the eye
Laser treatments or surgery to alter the drainage system of the eye
