Diagnosis
Home monitoring is not a diagnosis on its own – it is a way to track your vision. A formal diagnosis of an eye condition is made by an eye doctor (optometrist or ophthalmologist) through a comprehensive eye exam.
Tests that may be done
- Amsler grid test (for macular degeneration)
- Visual field test (for glaucoma)
- Snellen eye chart (for visual acuity)
- Home perimetry devices (for side vision)
What to expect at your appointment
Your eye care provider will teach you how to use the specific home test. You will be asked to do it regularly (e.g., daily or weekly) and record results. If you notice changes, you contact your provider.
Treatment
If home monitoring reveals changes, your eye doctor will examine you and may recommend treatments to protect your vision.
Self-care at home
- Use the monitoring tool as directed
- Keep a log of results (date, time, any changes)
- Avoid rubbing your eyes
- Manage underlying conditions like diabetes and blood pressure
Medical treatments
Treatments depend on the condition and may include medications (such as eye drops or injections), laser therapy, or other procedures. Your doctor will discuss the best options for you.
When is surgery considered?
Surgery may be considered for conditions like cataracts or certain types of glaucoma – your eye specialist will explain if this is needed.
Living with this condition
Home monitoring becomes part of your routine, like checking your blood pressure. It gives you confidence that you are catching changes early.
