Suspected glaucoma?
I would like to ask about seeing strange irregular black spots in my field of vision.
They are stationary and concentrated around the periphery of my vision.
I can still see them even when I place my hand over the area of the black spots.
Could this be a symptom of glaucoma? My eye pressure seems to be within normal limits.

More Info
The presence of irregular black spots in your vision can be concerning, and it's understandable to seek clarity on whether this could indicate glaucoma. Based on the information provided, it seems that the black spots you are experiencing are not typical symptoms of glaucoma, especially since your intraocular pressure (IOP) remains within normal limits. Glaucoma is primarily characterized by damage to the optic nerve, often associated with elevated eye pressure, and it typically presents with peripheral vision loss rather than isolated black spots.
The irregular black spots you describe, which are stationary and concentrated in your peripheral vision, may be more indicative of other ocular conditions. One possibility is that these spots could be related to floaters, which are small clumps of gel or cells inside the vitreous (the clear gel that fills the eye). Floaters can appear as dark spots or shadows in your field of vision and are often more noticeable against bright backgrounds. They are generally harmless but can be bothersome.
Another potential cause for the black spots could be related to retinal issues, such as retinal tears or detachment, which can also lead to the perception of dark spots or shadows. However, these conditions are usually accompanied by other symptoms, such as flashes of light or a sudden increase in floaters, and would typically require immediate medical attention.
Given that your eye pressure is normal and you have not reported any other symptoms commonly associated with glaucoma, it is unlikely that your black spots are a sign of this condition. However, it is essential to follow up with an eye care professional for a comprehensive examination. They may perform tests such as a dilated eye exam, optical coherence tomography (OCT), or visual field testing to assess the health of your retina and optic nerve more thoroughly.
In summary, while irregular black spots in your vision can be alarming, they are not typically associated with glaucoma, especially in the context of normal eye pressure. It is crucial to continue monitoring your symptoms and consult with an eye specialist who can provide a detailed evaluation and determine the underlying cause of your visual disturbances. If you notice any changes in your vision, such as an increase in the number of spots, flashes of light, or a curtain-like shadow over your vision, seek immediate medical attention.
