Phthisis bulbi causes permanent blindness in your affected eye. Causes typically include eye injuries or health conditions that damage your eyes over time. Visit an eye care specialist as soon as you notice any changes in your eyes or vision. They can treat many of the conditions that later cause phthisis bulbi.
Phthisis bulbi (TYE-suhs bul-BEE) is the medical term for your eye after damage causes it to stop working forever. Another name for phthisis bulbi is end-stage eye. Causes include anything that badly injures your eye or its parts. You’ll permanently lose vision in your affected eye if you have phthisis bulbi. You also won’t be able to move or control that eye.
Phthisis bulbi is different from common age-related eye problems. Age or the natural result of your eye changing over time don't cause it. It happens when something damages your eye so badly that there isn't treatment, and it won’t heal.
Damage that permanently stops your eye from functioning causes phthisis bulbi. The damage can happen suddenly (like during a trauma) or over time (as a result of conditions that cause inflammation in your eyes). The parts of your eye that can be affected by phthisis bulbi include your:
Your eye’s appearance will also change. It'll look different than it usually does — and different from your other eye. These changes can include:
There's no treatment for phthisis bulbi, and healthcare providers can't repair the damage it causes. However, an eye care specialist can treat many of the conditions that eventually lead to end-stage eye before the conditions cause irreversible damage.
Visit an eye care specialist if you notice any changes in your eyes or vision. The sooner a specialist diagnoses your symptoms, the less likely it is the symptoms will lead to phthisis bulbi.

Phthisis bulbi typically affects people older than 65. They’re more likely to develop health conditions that can damage their eyes.
However, anyone can develop end-stage eye. Kids and younger adults can develop phthisis bulbi after a trauma or because of a congenital condition (diseases or disorders you’re born with).
People with certain autoimmune diseases might have a higher risk of developing phthisis bulbi. Inflammation that happens a lot (chronic inflammation) can damage your eyes over time. Talk to an eye care specialist about your risk factors. Some common inflammatory diseases that can lead to phthisis bulbi include:
Vision loss in your affected eye is the most obvious symptom of phthisis bulbi. This blindness will be permanent and untreatable. An eye care specialist might refer to this blindness as disorganization — the medical term for untreatable changes inside your eye.
Phthisis bulbi symptoms include:
Anything that damages your eye enough to permanently stop it from working can cause phthisis bulbi. The most common causes include:
Conditions that damage your eye over time can lead to phthisis bulbi. The most common eye conditions that cause end-stage eye include:
An eye care specialist will diagnose phthisis bulbi with an eye exam. They’ll look at your eye (including inside it) for signs of scarring and other damage that means you have end-stage eye.
There’s no treatment for phthisis bulbi that'll restore your vision. By the time you have end-stage eye, the damage to your eye is irreversible.
Your eye care specialist might recommend removing your affected eye and replacing it with a prosthetic (artificial replacement) eye. The specialist can match your prosthetic eye with your healthy eye. This is a cosmetic procedure. It can’t restore your vision.
Removing your affected eye can eliminate pain and swelling.
The only way to prevent phthisis bulbi is to see an eye care specialist as soon as you notice any changes in your eyes or experience new symptoms. An eye care specialist can diagnose and treat many of the conditions that lead to end-stage eye before they cause permanent damage.
You can’t prevent a trauma from causing phthisis bulbi. Make sure you’re wearing proper eye protection for any sport or activity that could cause an eye injury.
Having your eyes and vision checked regularly can help your eye care specialist identify problems right away. How often you get your eyes checked usually depends on your age:
You might need eye exams more often than this if you wear glasses or contacts or need another type of visual aid. If you have diabetes, you must get eye exams more frequently.
Ask your eye care specialist how often you need an eye exam.
You should expect phthisis bulbi to be permanent. Once a specialist diagnoses phthisis bulbi, it's too late to treat it or restore your sight.
You might have other symptoms or complications depending on what caused phthisis bulbi, especially if you experienced a trauma. Talk to your healthcare provider about what to expect.
Visit an eye care specialist as soon as you notice any changes in your eyes or vision. Getting a specialist to examine new symptoms before the cause of your symptoms can damage your eyes is the only way to prevent phthisis bulbi.
Go to the emergency room if you’ve experienced a trauma, or if you experience a sudden loss of vision.
