Panophthalmitis
Severe infection involving all layers of the eye
Quick Facts
- Type: Severe eye infection (emergency)
- Extent: All coats and contents of the eye
- Common causes: Bacteria, sometimes fungi
- Urgency: Immediate medical care required
Overview
Panophthalmitis is a severe infection and inflammation that involves all the layers of the eye, including the inner contents and the outer protective coats, and often the surrounding tissues of the eye socket. It is more extensive and serious than endophthalmitis, which is limited to the inner eye.
Panophthalmitis is a medical emergency. The intense infection can rapidly destroy the eye's structures, threatening both vision and the eye itself, and in some cases the infection can spread beyond the eye. Immediate evaluation and treatment are essential to control the infection, relieve pain, and prevent dangerous complications.
Panophthalmitis usually develops from a severe infection that gains a foothold in the eye and then spreads through all of its layers. It can follow a penetrating injury, eye surgery, or an inner-eye infection that is not controlled, and it can also arise when germs travel to the eye through the bloodstream from an infection elsewhere in the body. People with diabetes or weakened immune systems are more vulnerable. Because the infection is so aggressive, the focus is often on stopping its spread and protecting the person's overall health rather than on saving vision in the affected eye.
Symptoms
Symptoms are usually severe and come on quickly. They may include:
- Severe eye pain
- Marked redness and swelling of the eye and surrounding eyelids
- Significant loss of vision
- Bulging of the eye (proptosis)
- Limited or painful eye movement
- Discharge or pus, and a hazy or cloudy appearance of the eye
- Fever and feeling generally unwell
Because these symptoms reflect a destructive, spreading infection, they require emergency care without delay.
Causes
Panophthalmitis is usually caused by an aggressive infection that overwhelms the eye. Routes of infection include:
- Penetrating injury: A wound that introduces bacteria or fungi directly into the eye.
- Eye surgery: Infection following an operation on the eye.
- Spread from nearby infection: Such as severe inner-eye infection or infection of the eye socket.
- Bloodstream spread: Germs carried to the eye from an infection elsewhere in the body, more likely in people with weakened immunity.
Bacteria are the most common cause, but fungi and other organisms can also be responsible.
Risk Factors
- Penetrating eye injury, especially with retained foreign material
- Recent eye surgery
- Untreated or severe inner-eye infection
- A weakened immune system
- Serious infection elsewhere in the body
- Poorly controlled diabetes
Diagnosis
Because panophthalmitis is an emergency, diagnosis is made rapidly based on the clinical picture, with tests to guide treatment. Evaluation may include:
- Urgent eye examination: Assessing the severity and extent of infection.
- Imaging: Ultrasound or CT to see how far the infection has spread, including into the eye socket.
- Samples for testing: Fluid or tissue from the eye, and blood cultures, to identify the responsible organism.
Treatment
Treatment is urgent and aggressive, aiming to control the infection and prevent it from spreading. It may include:
- Strong antibiotics or antifungals: Given intravenously and sometimes directly into or around the eye.
- Pain control and supportive care: To manage severe symptoms.
- Surgery: In advanced cases where the eye cannot be saved, removal of the eye (enucleation or evisceration) may be necessary to control the infection and protect overall health.
Preserving vision is often not possible once panophthalmitis is established, so the priorities are stopping the infection, relieving pain, and preventing it from spreading to the brain or bloodstream. Treatment is usually managed in the hospital by an eye specialist, often together with doctors who handle serious infections, and the chosen antibiotics or antifungals may be adjusted once the responsible organism is identified. In people with diabetes or weakened immunity, controlling the underlying condition is also an important part of recovery.
When to See a Doctor
Panophthalmitis is an emergency. Seek immediate medical care or go to an emergency department if you have:
- Severe eye pain with marked redness and swelling
- Rapid loss of vision
- A bulging eye or inability to move the eye
- Pus or discharge with fever, especially after an eye injury or surgery
Do not wait. Prompt treatment is the best chance to control the infection and protect your health.
Frequently Asked Questions
How is panophthalmitis different from endophthalmitis?
Endophthalmitis is infection limited to the inner contents of the eye, while panophthalmitis involves all layers of the eye, including its outer coats and often the surrounding socket. Panophthalmitis is more severe and is a true emergency.
Can the eye be saved in panophthalmitis?
Often the infection is too destructive to preserve useful vision, and in advanced cases the eye may need to be removed to control the infection. The main goals become stopping the infection, relieving pain, and protecting overall health.
Is panophthalmitis dangerous beyond the eye?
Yes. The severe infection can potentially spread to the eye socket, bloodstream, or brain, which is why it is treated as an emergency with urgent antibiotics or antifungals and close monitoring.
What causes panophthalmitis?
It usually results from an aggressive infection entering the eye through a penetrating injury or surgery, spreading from a nearby infection, or traveling through the bloodstream. Bacteria are the most common cause, but fungi can also be responsible.
What should I do if I have severe eye pain and vision loss after an injury?
Seek emergency care immediately. Severe pain, swelling, and rapid vision loss after an eye injury or surgery can indicate a sight- and health-threatening infection that needs urgent treatment.
