Is drug-induced glaucoma considered a form of chronic glaucoma?

Hello Doctor, I am working overseas and recently purchased eye drops containing corticosteroids for conjunctivitis.
After using them for ten days, I developed glaucoma.
I consulted a local doctor and was prescribed glaucoma medication and eye drops.
After three days of treatment, I returned to Taiwan and stopped the glaucoma medication.
Two days later, I underwent an eye scan, visual field test, and slit-lamp examination.
The doctor in Taiwan indicated that my eyes are currently normal and my intraocular pressure is stable.
I am scheduled for a follow-up in six months.
However, I have noticed that after using my iPad and computer for a while, I experience tightness at the back of my head and mild dizziness, which can be alleviated after exercising.
I am a bit concerned whether this could be a symptom of open-angle glaucoma.

Hello, Pan: When experiencing eye fatigue, it can lead to increased intraocular pressure, causing discomfort.
Exercise can sometimes lower intraocular pressure, providing relief.
However, the discomfort may also be due to excessive eye strain.
Exercise allows the eyes to rest, which can alleviate symptoms.
A six-month follow-up may be a bit lengthy; initially, I recommend measuring your intraocular pressure when you feel discomfort to determine if it's related to pressure changes.
Medication-induced changes are often temporary and may return to normal after discontinuation.
The ophthalmology department at Puzi Hospital in Taiwan is open Monday to Friday from 8:00 AM to 12:00 PM and Wednesday afternoons from 1:00 PM to 4:30 PM.
Online responses should only be used as a reference; if necessary, it is important to seek care at a medical facility.
I hope to have the opportunity to assist you.

More Info

Medication-induced glaucoma, particularly from corticosteroid eye drops, can indeed lead to long-term eye issues if not managed properly. Corticosteroids can increase intraocular pressure (IOP) in susceptible individuals, potentially leading to glaucoma. In your case, it appears that after using a corticosteroid eye drop for ten days, you experienced a spike in IOP, which is a common side effect of these medications.
Fortunately, you mentioned that after stopping the glaucoma medication and undergoing various eye examinations, your eye health was deemed normal, and your IOP was stable. This is a positive sign, indicating that the acute effects of the medication may have resolved. However, it is essential to remain vigilant about any symptoms that may arise in the future.

The symptoms you describe—tightness in the back of your head and mild dizziness after prolonged screen time—could be related to several factors, including eye strain, tension headaches, or even postural issues while using your devices. While these symptoms are not definitive indicators of open-angle glaucoma, they warrant attention, especially given your recent history of elevated IOP.

Here are some considerations and recommendations based on your situation:
1. Regular Monitoring: Since you have a history of medication-induced glaucoma, it is crucial to have regular eye exams, especially if you experience any new symptoms. Follow your doctor's advice about returning for follow-up appointments, and do not hesitate to seek care sooner if your symptoms worsen.

2. Screen Time Management: Prolonged use of screens can lead to digital eye strain, which may cause discomfort and headaches. Implementing the 20-20-20 rule—taking a 20-second break to look at something 20 feet away every 20 minutes—can help alleviate some of the strain on your eyes.

3. Hydration and Breaks: Ensure you stay hydrated and take regular breaks during your work or leisure activities involving screens. This can help reduce the likelihood of headaches and dizziness.

4. Posture and Ergonomics: Evaluate your workspace setup. Poor posture can contribute to tension headaches and discomfort. Ensure your screen is at eye level, and your chair supports your back properly.

5. Consultation with Specialists: If your symptoms persist or worsen, consider consulting both an ophthalmologist and a neurologist. The ophthalmologist can monitor your eye health, while the neurologist can help assess any potential neurological causes for your symptoms.

6. Medication Review: If you are still using any eye drops or medications, discuss them with your healthcare provider to ensure they are appropriate for your current condition and do not pose a risk of increasing IOP.

In summary, while your current eye health appears stable, ongoing vigilance is essential. Monitor your symptoms closely, maintain regular check-ups, and make adjustments to your screen time habits to minimize discomfort. If you have any concerns about your symptoms or eye health, do not hesitate to reach out to your healthcare provider for further evaluation and guidance.
