Q&A on Glaucoma with Dr. Lewis – part 2

This is part 2 of our interview with Dr. Lewis on the topic of Glaucoma.

Q: How can I tell if I have glaucoma?

Regular eye exams can detect glaucoma at an early stage.  Treatment to prevent vision loss from glaucoma on those diagnosed early is usually able to prevent vision loss.

Q: How is glaucoma detected?

During an eye exam, we evaluate the intraocular pressure and we assess the health of the optic nerve.  If a patient is deemed a glaucoma suspect, we will likely recommend a threshold visual field assessment to determine if there are changes in vision attributable to glaucoma.  Retinal imaging to monitor for optic nerve health changes over time is also ideal.

Q: How is glaucoma treated?

Glaucoma is most commonly controlled with eyedrop medication that lowers the pressure by either reducing the amount of fluid made by the eye or by enabling better fluid outflow through the drainage angle.

Surgery for glaucoma is also sometimes recommended.  In those cases, we would consult with a glaucoma specialist to determine if surgical intervention would be indicated.

Q: Can glaucoma be prevented?

While there are no known ways of preventing open-angle glaucoma, vision loss or blindness can be prevented by early detection and intervention to prevent damage to the optic nerve. Certain subsets of glaucoma such as narrow angle glaucoma is treatable through a surgical procedure called a laser iridotomy.

Dear Patients,

Dr. Lewis Eye Care has made the difficult choice to temporarily close due to the COVID-19 virus pandemic based on the recommendation of the CDC. We cannot perform eye exams while maintaining social distancing, so continuing to see patients at this time could contribute to the spread of the virus.

Our initial plan had been to reopen Monday April 6th. However, as we get closer to that date it is becoming apparent that we may have to be closed for a longer, indefinite period of time.

If you are having an urgent eye health issue, there are some clinics in our area that are seeing patients for emergencies during shorter business hours. You should call ahead to those offices before going to their clinic, as their availability might change day by day. Those clinics could include Vancouver Eye Care at 360-823-2020, Peace Health Medical Group Eye Care at 360-514-7210, and Vancouver Clinic in Salmon Creek at 360-882-2778.

If you need a glasses or contact lens prescription emailed to you from our office, click on the Contact Form link, type in your name, email, and what you are requesting, and we will email you the information you need as soon as we can.

Thank you for your understanding, and please stay healthy during this difficult time.


Dr. Scott Lewis, OD
