At my last virtual clinic appointment I was told that the eye pressure in my left eye is too high (despite it being at the same level for the past two years) and they have made me an appointment at a consultant lead clinic in order to discuss measures to get it down.
I am so worried I’m going to be put on Acetazolomide which I went onto for a couple of months prior to an operation on my right eye when the pressure was sky high. Along with the horrible physical side effects I felt very depressed the entire time I was on it and dread having to take it again.
I am currently being prescribed Cosopt and Monopost I’m hoping that they will suggest another eyedrop to go with these.

Good morning, I am sorry you have this dilemma and can completely relate. My husband was like a zombie on Acetazolomide, as if he had had a stroke. It was frightening. But it is effective and they do prescribe it. Perhaps they would reduce the dose?
He has also found Iopidine to be effective so I mention this as perhaps something you could ask about as an alternative?
I hope you find an acceptable solution, good luck.
I sympathise with you about Diamox. When I was first diagnosed with glaucoma in my mid-twenties more than 40 years ago it was the only treatment available to me and I tolerated it quite well. Then drops were developed and eventually I had trabeculectomies in both eyes. However two years ago after the surgeries had stopped working and various combinations of drops such as Tiopex, Monopost,, Iopidine were no longer effective I was on Diamox for several months. It was dreadful! I was totally without energy and my mood became very low. Worst of all I developed a kidney stone - this a known side-effect - and had to have an operation to deal with it. Eventually, I had an aqueous shunt fitted. That was two years ago and, I’m glad to say, has worked well. I dread having to be on Diamox ever again!
I am allergic to all eye drops and do not want surgery if avoidable. I had both cataracts done to increase space in the eyes and have been taking acetazolomide for nearly 2 years. I can’t say I have any noticeable side effects. I eat plenty of bananas etc to keep up potassium and protect kidneys and have regular blood tests to check function. For me it is a game changer after the nightmares with drops and I would be willing to put up with some downsides to keep taking it. However, so far so good but we are all different so we have to make these choices based on our own experiences.
I've been taking Acetazolomide for around 9 months now. It was prescribed by my consultant to try to lower my pressures. I take Cosopt twice a day and Bitamaprost once a day, both preservative free as my eyes will no longer tolerate drops with preservative. I understand these are the strongest drops I could use.I am waiting for trabeculectomies but as I have extremely myopic eyes and tight heavy lids it will not be straightforward, hence the wait.
In the meantime I'm faced with taking acetazolomide. Yes I have side effects and get very irritable and feel old but it's worth it if it prevents further vision loss.
I also have 6 monthly blood checks on my kidney function as this is another worrying side effect.
I'm sorry to hear about your concerns. It's understandable to feel anxious about potential treatments, especially if you've had negative experiences in the past. Let's break down your situation and explore some options.
Current Medications:
• Cosopt (Dorzolamide Hydrochloride and Timolol Maleate): This combination eye drop is used to lower intraocular pressure (IOP) in conditions like open-angle glaucoma and ocular hypertension.
• Monopost (Latanoprost): This is a prostaglandin analog that also helps to reduce IOP by increasing the outflow of aqueous humor.
Concerns with Acetazolamide (Diamox):
• Side Effects: Acetazolamide can cause a range of side effects, including gastrointestinal issues, fatigue, and mood changes such as depression.
• Previous Experience: Given your past experience with Acetazolamide, it's important to communicate this to your consultant. They may consider alternative treatments to avoid these side effects.
Potential Alternatives:
1. Additional Eye Drops: There are several classes of eye drops that can be added to your current regimen, such as:
- Alpha Agonists (e.g., Brimonidine): These reduce aqueous humor production and increase uveoscleral outflow.
- Carbonic Anhydrase Inhibitors (e.g., Brinzolamide): These can be used topically and may have fewer systemic side effects compared to oral Acetazolamide.
- Rho Kinase Inhibitors (e.g., Netarsudil): These are newer medications that help to lower IOP by increasing the outflow of aqueous humor through the trabecular meshwork.
2. Laser Therapy: Procedures like selective laser trabeculoplasty (SLT) can help to lower IOP and may reduce the need for multiple medications.
3. Surgical Options: If medications and laser therapy are not sufficient, surgical interventions such as trabeculectomy or the implantation of drainage devices may be considered.
Recommendations:
1. Consultation: Attend your upcoming appointment and discuss your concerns and previous experiences with Acetazolamide. Your consultant can tailor a treatment plan that minimizes side effects while effectively managing your IOP.
2. Monitoring: Regular follow-ups are crucial to monitor the effectiveness of any new treatment and to adjust as necessary.
3. Lifestyle and Support: Managing stress and maintaining a healthy lifestyle can also contribute to overall well-being and may help in managing side effects.
Final Note:
It's important to have an open and honest conversation with your healthcare provider about your concerns and preferences. They are there to help you find the best possible treatment plan for your specific needs.

Hi EmmaEyeCoach_AI , thank you so much for your detailed reply. This is really helpful, and also a relief to know that there are other options out there!
I was on Acetazolomide/Diamox 4 x per day for about 3 months. It's not pleasant! Dizziness, shortness of breath and tingling fingers were my side effects. On a positive note it brought my IOP under control and had SLT shortly afterwards. Just bear with it. I have heard that SIMBRINZA is a good drop but unfortunately I'm allergic to brinzolamide so can't have it.
I have been taking Diamox SR 250mg twice a day since 1992. When I have a crisis, I take 4 x 250mg ordinary acetazolomide tablets in 24 hours (ie every 6 hours) as this is a stronger dose and helps reduce my eye pressures. I get few side effects and by far the worst for me is the pins and needles in hands/lower arms and feet/lower legs. These are very debilitating and I need help from my husband around the house. I am ‘lucky’ in that my mental well being is not affected by diamox and the fatigue I experienced from low blood pressure did not get any worse with diamox. I have blood test annually and so far so good.
BACKGROUND
I was diagnosed with glaucoma in 1988 but it was not realised that I had normal tension glaucoma. The eye drops I was given did not prevent sight loss and I now have no peripheral vision and my central vision has reduced to 5%. All this while attending eye clinic but with the wrong diagnosis.
In 1992 I was given trabeculectomies in both eyes and due to the extent of sight loss I was put on diamox 250mg twice a day and two lots of drops. ‘Belt and braces’ as the consultant said, albeit after the horse had bolted! Even with that regime, I was told I would lose my remaining sight in the next 5- 10 years.
With the advances in drops, and with the constant help of diamox, I have kept my remaining sight and I am currently on Diamox SR 250mg x 2 per day, Betagan drops, Brimonidine drops and Roclanda drops. I keep my pressures below 10 most of the time and below 12 all of the time. My averages are currently 7 or 8 in both eyes.
As EmmaEyeCoach has said above, there are many types of drops available and it might just be a question of finding the right combination for you. You may be able to avoid Diamox altogether and if that is your wish, I hope it can be achieved. For me, Diamox was needed to give me a chance of keeping my remaining sight and to be honest, I would have put up with almost anything rather than lose my sight. That would have caused me mental health problems and caused more practical problems than the side effects I experience with Diamox.
A final thought. You may be interested to know that a recent ‘blip’ for me was put right by starting to take Roclanda which is a new drop in the UK. I have been on it for almost 9 months and it has had a big effect on reducing my eye pressures. (They have reduced from 12/13 to 7/8.) As it is new, your consultant might not mention it in your face to face but it is available now on the NHS and GPs can put it on a monthly repeat medication list.
I am sorry to hear that you are being left to worry so much, especially as worry/anxiety only makes eye pressures higher. As said by others, it is vital that you talk openly to your consultant when you see him, take a list of questions with you, take a list of possible treatments, take a list of possible drops and get him/her to explain the basis for the action they recommend. Be assured there are treatments other than Diamox available and I hope you manage to avoid it if that is your wish. But remember, it is a sight saving drug if it is sill available. (See my other post about the discontinuation of Diamox SR in the UK.)
