Please listen to your doctor and see him/her as often as your insurance will allow. Glaucoma can progress very slowly or by leaps and bounds. When I moved from my home of 49 years into a retirement community, I had to find all new doctors. I had to wait a few extra months for an appointment with a opthamologist, and my bad eye worsened in the process. Because a Timolol prescription caused my cornea to turn cherry-red, my new doctor prescribed a preservative-free brand called Iyuzeh, which is much more expensive. Fortunately, a kind pharmacist at my new CVS helped me and my doctor fill out a form to get Iyuzeh by mail at a reduced cost. I have cut my final cost still further by using each single-dose applicator twice instead of once. The vial caps that come with each dose of Iyuzeh cannot be put back on. However, you can replace each of those applicator caps as you remove it with one that comes from a single-use vial of Refresh or Systane, which are OTC brands of artificial tears.
You may want to use the artificial tears midway between the doses of your prescription to prevent dry eyes from adding to your problems.
My last doctor also had me applying for ten minutes a day a pellet-filled, “Thermalon” eye mask that I heat for 20 seconds in the microwave. This may help by stimulating the tiny glands at the base of the eyelashes. I bought the mask at amazon.com. Do arm exercises or listen to a book or a podcast while you are “in the dark.”
The good news, according to my new opthamologist, is that glaucoma usually affects just one eye. With regular doctor visits, tests, and eyedrops, you can slow its progress and be proactive should it begin to show up in the other eye.
I wish you the best of health.
