Eye Issues: Symptoms of Possible Glaucoma Explained - Ophthalmology

Hello! It sounds like you're experiencing a range of concerning symptoms related to your vision, and I understand how worrying this can be. Based on your description, it seems you are experiencing visual disturbances such as flashes of light, a flickering sensation, and halos around lights, particularly at night. Additionally, you mentioned having slight eye pain and headaches.
First, let's discuss the symptoms you are experiencing. The flashes of light and flickering sensations can be associated with several conditions, including retinal issues, migraines, or even visual disturbances related to high myopia (nearsightedness). In your case, since you have a history of myopia (550 degrees), it's essential to consider that high myopia can lead to various complications, including retinal detachment or degeneration, which could explain some of the visual symptoms.

The halos around lights, especially noticeable at night, can also be linked to refractive errors or changes in the eye's lens, which can occur with myopia. However, these symptoms can also be indicative of glaucoma, particularly if there is an increase in intraocular pressure (IOP) or if there are changes in the optic nerve. Your reported eye pressure of 19-20 mmHg is within the normal range, but it is on the higher side of normal, which can be a concern, especially if you have other risk factors for glaucoma.

Regarding your question about acute glaucoma, the symptoms you describe do not necessarily point to acute angle-closure glaucoma, which typically presents with sudden severe eye pain, nausea, vomiting, and a rapid increase in eye pressure. However, it is crucial to monitor your symptoms closely, as any changes could indicate a need for immediate medical attention.

The slight eye pain and headaches you are experiencing could be related to eye strain, especially if you spend long hours focusing on screens or reading. Eye strain can lead to discomfort and visual disturbances, particularly in individuals with myopia. It is advisable to take regular breaks, practice the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds), and ensure your workspace is well-lit to reduce strain.

Since you have already seen multiple eye specialists and have scheduled a comprehensive eye examination, this is a positive step. During this examination, the doctors will likely perform tests such as visual field testing, optical coherence tomography (OCT), and a thorough assessment of your optic nerve health. These tests will help determine if there are any signs of glaucoma or other underlying conditions.

In the meantime, here are some recommendations to help manage your symptoms:
1. Monitor Symptoms: Keep a detailed log of your symptoms, including when they occur, their duration, and any potential triggers. This information can be valuable for your eye care provider.

2. Reduce Eye Strain: Ensure you take regular breaks from screens and practice good lighting habits while reading or working.

3. Stay Hydrated: Dehydration can sometimes exacerbate headaches and eye discomfort, so make sure you drink enough water throughout the day.

4. Follow Up: Attend your scheduled eye examination and discuss all your symptoms in detail with your eye care provider. If your symptoms worsen before your appointment, do not hesitate to seek immediate medical attention.

5. Consider a Second Opinion: If you continue to feel uncertain about your diagnosis or treatment plan, seeking a second opinion from another eye specialist can provide additional reassurance.

In conclusion, while your symptoms are concerning, they do not definitively indicate acute glaucoma. However, it is essential to remain vigilant and proactive in seeking care. Your upcoming eye examination will provide more clarity, and I encourage you to discuss all your symptoms thoroughly with your eye care provider. Take care of your eyes, and I wish you the best in your upcoming appointment!
