Eye Pressure and Floaters: Common Concerns Explained - Ophthalmology

Intraocular pressure, floaters?


Hello, Doctor; I would like to ask about intraocular pressure.
Generally, I feel a sense of pressure in my eyes, but sometimes the pressure feels heavier, particularly in the area between my eyebrows, which feels slightly relieved.
Is this related to intraocular pressure? Also, right now, while typing on this white background, I see some small black dots that float and move with my gaze.
Is this what is known as floaters? Lastly, I am just looking to check if there are any issues and if there are ways to improve my condition.
Would making an appointment for this be considered a waste of medical resources? It seems like everyone only goes to the doctor when they are sick, but I am just here for a check-up.
I have had this question for a long time.
Thank you, Doctor.

Dear Ade, intraocular pressure refers to the pressure inside the eye, which can only be measured with special instruments.
Sometimes, excessive eye use can lead to fatigue and a feeling of pressure, often due to tension in the muscles around the eyes; local massage can help relieve this.
Your symptoms are indeed indicative of floaters, and many people seek medical attention for this condition.
There's no need to worry; you can go directly to the outpatient clinic for a dilated fundus examination.
Sincerely, Jing-Yao.

Dear Patient,
Thank you for your questions regarding eye pressure and floaters. It’s great that you are taking the initiative to understand your eye health better. Let’s address your concerns one by one.

1. Understanding Eye Pressure: Eye pressure, or intraocular pressure (IOP), is the fluid pressure inside the eye. It is typically measured in millimeters of mercury (mmHg). Normal IOP ranges from 10 to 21 mmHg. When you feel pressure around your eyes, particularly in the area between your eyebrows, it may not necessarily indicate high eye pressure. Instead, it could be due to muscle tension or fatigue, especially if you have been straining your eyes, such as when reading or using a computer for extended periods. If the pressure sensation persists or is accompanied by pain, it would be wise to consult an eye care professional.

2. Floaters: The small black dots you see drifting across your vision, especially against a bright background, are indeed likely to be floaters. Floaters are tiny clumps of gel or cells inside the vitreous, the clear gel that fills the space between the lens and the retina of your eye. They are common and usually harmless, especially if they are not accompanied by flashes of light or a sudden increase in number, which could indicate a more serious condition like a retinal tear.
3. Seeking Medical Attention: Your concern about potentially wasting medical resources by seeking an eye examination is understandable. However, it is important to remember that regular eye check-ups are crucial for maintaining eye health, especially if you notice changes in your vision or experience symptoms like floaters or pressure. Many people visit eye care professionals for preventive care or to address minor concerns, and this is not a waste of resources. Early detection of issues can prevent more serious conditions from developing.

4. Eye Pressure and Symptoms: It’s important to note that not everyone with high eye pressure will experience symptoms. Some individuals may have elevated IOP without any noticeable discomfort, while others may feel pressure or pain even with normal IOP. If you are experiencing persistent discomfort or changes in your vision, it is advisable to have a comprehensive eye exam, which may include measuring your IOP, examining your optic nerve, and assessing your overall eye health.

5. Floaters and Eye Health: While floaters are usually benign, if you notice a sudden increase in floaters or if they are accompanied by flashes of light or a shadow in your peripheral vision, you should seek immediate medical attention. These could be signs of a retinal detachment, which is a serious condition that requires prompt treatment.

In conclusion, it is commendable that you are proactive about your eye health. Regular check-ups with an eye care professional can help monitor your eye pressure and address any concerns regarding floaters or other symptoms. Remember, it is always better to be cautious and seek advice when it comes to your vision. If you have further questions or concerns, don’t hesitate to reach out to your eye care provider.

Best regards,
