![]() ![]() Eye StrokesĮye strokes, also referred to as retinal artery occlusion, are caused by clots in your eye's blood vessels. ONA may cause peripheral, central, or color vision loss. Optic nerve atrophy is damage or degeneration of your optic nerve due to trauma, infection, insufficient oxygen or blood supply, tumors, or other causes. These conditions are inherited genetically and affect the retina, resulting in night blindness, PVL, tunnel vision, and other vision problems. Retinitis Pigmentosa, or RP, refers to a group of eye conditions caused by genetic mutations. Glaucoma is a disease that causes optic nerve damage, often due to elevated intraocular pressure. Glaucoma is the most common cause of peripheral vision loss. Loss of peripheral vision may be the result of: Glaucoma Peripheral vision loss can be caused by eye diseases, eye injuries, or other injuries and conditions that occur outside of the eye. Increased or decreased light sensitivity.Symptoms of peripheral vision loss include: This is often referred to as tunnel vision. Moderate to severe PVL may cause it to seem like you’re looking down a narrow tube. You may have visual symptoms that affect your side vision, even if your central vision is acute. If you have permanent peripheral vision loss, consider consulting a low vision specialist who can guide you about special optical devices or eyewear to aid with mobility problems due to tunnel vision.Peripheral Vision Loss, also known as PVL, means that your field of vision is not as wide as it should be. Keep in mind that reduced peripheral vision may hinder safe driving. Despite normal vision, some techniques that sports vision specialists use may be helpful to train yourself to see better in your peripheral visual field. Some therapies may also be prescribed for treating blind spots caused by brain damage. Left untreated, glaucoma may lead to permanent peripheral vision loss and even blindness. Regularly take glaucoma medication to manage high eye pressure and risks of permanent optic nerve damage. If you have a condition like glaucoma, the best treatment for tunnel vision is prevention. A special prism lens can sometimes be added to your prescription eyeglasses to expand the visual field for mild cases of peripheral vision loss. Conventional eyeglasses or contact lenses cannot correct permanent peripheral vision loss. Sadly, there are no simple vision correction treatments available to treat peripheral vision loss. Sudden loss of peripheral vision may signify a detached retina that could mean a medical emergency that requires treatment as soon as possible to prevent blindness. If you suspect any decrease or loss in your peripheral vision, visit your eye doctor right away for an eye exam that includes visual field testing. Common causes of peripheral vision loss include: Eye “strokes” or occlusions that obstruct normal blood flow to the internal structures of the eye such as the optic nerve can lead to peripheral vision loss or tunnel vision.Ī stroke or injury may also damage areas of the brain that process images which can lead to blind spots in the visual field. Symptoms of peripheral vision loss include trouble seeing in dim light and decreased sense of navigation while walking.Ī common cause of peripheral vision loss or also called peripheral field defect is damage on the optic nerve-related to glaucoma. Moderate to severe cases of peripheral vision problems may seem like looking through a narrow tube where its name “tunnel vision’ is derived from. This means that you do not have a normal wide-angle field of vision despite the central vision being fine. Tunnel vision means loss of peripheral vision.
