Is Your Eye Pressure Too High? Symptoms and Risks - Ophthalmology

Is this a sign of elevated intraocular pressure?


I've been experiencing a feeling of swelling in my eyes for the past week, and I don't feel like looking at things.
However, I sleep more than 8 hours every day.
Could this be due to high intraocular pressure? I have high myopia and spend a lot of time on the computer.
Additionally, I would like to ask if this could be related to the retina.
Thank you for your response.

It is recommended that you have your intraocular pressure measured by an ophthalmologist.
However, given your condition, there is a 99% chance that your eye pressure is normal.
Most individuals with genuinely elevated intraocular pressure do not experience any symptoms.
However, when the eyes are fatigued, the ciliary muscle inside the eye may spasm, leading to a sensation of aching and pressure.
For example, when you suddenly move from a dark room to bright light, do you feel a sudden ache and pressure in your eyes? This is a temporary phenomenon involving the contraction of the ciliary muscle and the iris.
Similarly, prolonged near work can lead to ciliary muscle spasm.
In fact, presbyopia can also present with similar symptoms, all of which are part of eye fatigue.

When it comes to eye pressure and its potential implications, particularly for individuals with high myopia (nearsightedness), understanding the symptoms and risks is crucial. Your recent experience of a swollen sensation in your eyes, coupled with a decreased desire to engage in visual tasks, raises valid concerns, especially given your history of high myopia and prolonged computer use.

Firstly, it’s important to clarify that elevated eye pressure, or intraocular pressure (IOP), is a significant risk factor for glaucoma, a condition that can lead to vision loss if not managed properly. However, the symptoms you describe—swelling and discomfort—are not definitive indicators of high eye pressure. In fact, many individuals with elevated IOP may not experience any symptoms at all. The sensation of swelling or pressure could be attributed to several factors, including eye strain, dry eyes, or even tension in the eye muscles, particularly after extended periods of screen time.

Given your situation, it’s essential to consider the following:
1. Eye Strain and Fatigue: Prolonged computer use can lead to digital eye strain, characterized by symptoms such as dryness, irritation, and a feeling of heaviness or swelling around the eyes. This condition can occur even if you are getting adequate sleep. The muscles that control eye movement can become fatigued, leading to discomfort.

2. High Myopia: Individuals with high myopia are at an increased risk for various ocular conditions, including retinal detachment and glaucoma. While high myopia itself does not directly cause elevated eye pressure, it can be associated with structural changes in the eye that may predispose you to these conditions.

3. Potential Retinal Concerns: Your question about whether these symptoms could relate to retinal issues is valid. High myopia can lead to degenerative changes in the retina, such as lattice degeneration or even retinal tears. If you experience sudden changes in vision, such as flashes of light or an increase in floaters, it is crucial to seek immediate medical attention.

4. Importance of Regular Eye Exams: Given your concerns about eye pressure and potential risks, regular eye examinations are vital. These exams typically include measuring IOP, assessing the optic nerve, and conducting visual field tests to evaluate for glaucoma. If you have not had a comprehensive eye exam recently, it would be prudent to schedule one sooner rather than later, especially if your symptoms persist.

5. Managing Anxiety and Stress: If you find that anxiety affects your ability to undergo eye examinations, it’s worth discussing this with your healthcare provider. Anxiety can indeed elevate blood pressure, which may, in turn, affect eye pressure readings. However, a thorough evaluation by an eye care professional will consider multiple factors beyond just IOP.

In summary, while your symptoms warrant attention, they do not automatically indicate high eye pressure or glaucoma. It is essential to consult with an eye care professional who can perform the necessary tests to determine the cause of your discomfort and assess your overall eye health. Regular monitoring and proactive management are key to maintaining good vision, especially for individuals with high myopia. If your symptoms worsen or you experience new visual disturbances, do not hesitate to seek immediate care.
