Black Spots in Vision: Is It Related to Eye Pressure? - Ophthalmology

The phenomenon of experiencing black spots or shadows in your vision can indeed be concerning, especially when accompanied by a history of conditions like floaters (known as "myodesopsia"). Based on your description, it seems that you are experiencing transient visual disturbances that may be related to your eye pressure and the health of your optic nerve.
Firstly, the presence of black spots or shadows in your vision, particularly when you close one eye, could be attributed to several factors. One possibility is that these shadows are related to the vitreous gel in your eye. As we age or due to certain eye conditions, the vitreous can become more liquid and may pull away from the retina, leading to the perception of floaters or shadows. This is often benign, especially if your recent eye examination showed no signs of retinal detachment or other serious issues.

Regarding your concern about optic nerve pressure, it is important to understand that elevated pressure in the eye (intraocular pressure) can lead to conditions such as glaucoma, which can damage the optic nerve and affect vision. If your doctor noted that your right eye has higher optic nerve pressure, it is crucial to monitor this condition closely. Elevated pressure can lead to visual field loss and other complications if not managed properly. However, the transient nature of your black spots, which disappear quickly with eye movement, may not be directly linked to optic nerve pressure but could be a result of how your brain processes visual information when the eye is in certain positions.

In terms of potential serious issues, while transient visual disturbances can be benign, they can also indicate underlying problems that require attention. Conditions such as retinal detachment, vitreous hemorrhage, or even neurological issues can present with similar symptoms. Therefore, it is essential to maintain regular follow-ups with your eye care professional, especially given your history of floaters and the noted pressure in your right eye.

To address your specific questions:
1. Is this related to high eye pressure? While transient black spots may not directly indicate high eye pressure, it is essential to monitor your intraocular pressure regularly, as elevated pressure can lead to significant eye health issues over time.

2. Should I be concerned about the black spots? If these black spots are new or have changed in frequency or intensity, it would be prudent to consult your eye doctor for a comprehensive examination. They may perform tests to assess your optic nerve health and intraocular pressure more thoroughly.

3. When should I seek medical attention? If you experience any sudden changes in your vision, such as an increase in the number of floaters, flashes of light, or a curtain-like shadow over your vision, you should seek immediate medical attention. Additionally, if the black spots persist or worsen, it is advisable to consult with an eye care professional.

In conclusion, while your symptoms may not immediately indicate a severe problem, they warrant careful monitoring and follow-up with your eye care provider. Regular eye exams are crucial for maintaining eye health, especially with your history of floaters and the noted optic nerve pressure. Always prioritize your eye health and do not hesitate to seek professional advice when you notice changes in your vision.
