Corneal perforation - a rupture in the corneal tissue due to traumatic or pathologic processes.

What causes corneal perforation?

• Corneal ulcers are most common cause of perforation.
• Corneal ulcers are caused by an infection with bacteria, viruses, fungi, or a parasite.
• Acanthamoeba keratitis occurs in contact lens users.
• Eyelids that do not close all the way, such as with Bell palsy
• Foreign bodies in the eye
• Scratches (abrasions) on the eye surface

What is gonococcal ophthalmia neonatorum?

Gonococcal ophthalmia neonatorum caused by a maternally transmitted gonococcal infection Unless preventative measures are taken, it is estimated that gonococcal ophthalmia neonatorum will develop in 28% of infants born to women with gonorrhea. It affects the corneal epithelium causing microbial keratitis, ulceration and perforation.

What are the signs and symptoms?

• Blurry or hazy vision
• Eye that appears red or bloodshot
• Itching and discharge
• Sensitivity to light (photophobia)
• Very painful and watery eyes
• White patch on the cornea

What tests are done?

• Exam of scrapings from the ulcer
• Fluorescein stain of the cornea
• Keratometry (measuring the curve of the cornea)
• Pupillary reflex response
• Refraction test
• Slit-lamp examination
• Tests for dry eye
• Visual acuity
• Blood tests to check for inflammatory disorders may also be needed.

What is the treatment?

• Treatment for infections depends on the cause.
• Treatment should be started as soon as possible to prevent scarring of the cornea.
• If the exact cause is not known, broad spectrum antibiotic drops that work against many kinds of bacteria.
• Corticosteroid eye drops may be used to reduce swelling and inflammation in certain conditions.
• Tissue adhesive can be used to seal small perforation, but this method cannot be used to treat perforations larger than 1 mm.
• Non infected corneal perforation generally heals when a pressure bandage is used.
• For certain types of corneal perforations, lamellar keratoplasty is used as treatment.

What are the complications?

Untreated corneal perforations/ulcer and infections may lead to:

• Loss of the eye (rare)
• Severe vision loss
• Scars on the cornea

Frequently Asked Questions about Corneal Perforation

• What happens if your cornea perforates?

If the cornea perforates, it can lead to loss of integrity in the eye, causing fluid to leak out and potentially leading to infection, vision loss, and globe rupture. Immediate medical attention is required to prevent further damage.

• How long does it take for a perforated cornea to heal?

The healing time for a perforated cornea depends on the severity of the injury. In mild cases, it may take several weeks, but more severe cases may require surgical intervention, such as a corneal transplant.

• How do you treat a perforated cornea?

Treatment for a perforated cornea often involves surgical repair, including suturing the perforation, and managing any underlying infection with antibiotics. In some cases, a corneal transplant may be needed.

• Can a hole in the cornea heal?

A small hole in the cornea may heal on its own with proper care, but larger or deeper perforations generally require medical intervention, such as surgery, to repair the damage.

• Can a ruptured eye heal?

A ruptured eye is a serious condition that often requires surgical intervention. The healing process depends on the extent of the injury, but it may result in permanent vision loss if not treated promptly.

• Can cornea repair itself?

The cornea has a limited ability to repair itself, particularly for minor injuries such as superficial scratches. However, more serious injuries, like a corneal perforation, usually require medical intervention.

• Will my vision come back after corneal ulcer?

If treated properly, vision can return after a corneal ulcer; however, severe cases may lead to scarring or permanent vision loss. The success of recovery depends on the extent of the ulcer.

• Can a cornea burst?

While the cornea itself does not "burst," a corneal rupture can occur, which is a more serious condition where the cornea is torn or punctured, leading to fluid leakage and potential loss of vision.

• Will corneal ulcers heal on their own?

Some minor corneal ulcers may heal with conservative treatment, but more severe ulcers, especially those caused by infection, require medical intervention, including antibiotics or antiviral treatment.

• What causes corneal rupture?

Corneal rupture is typically caused by trauma, such as blunt force or sharp objects, that causes a tear or puncture in the corneal tissue. It may also be due to underlying conditions like glaucoma or corneal dystrophies.

• What causes corneal perforation?

Corneal perforation can result from trauma, infection, or conditions like keratoconus or corneal ulcers. It can also occur as a complication of eye surgery or ocular chemical burns.

• How do you damage your cornea?

The cornea can be damaged by trauma, foreign bodies, infections, chemical exposure, or conditions like dry eye or contact lens misuse.

• Is a hole in the eye serious?

Yes, a hole in the eye, particularly in the cornea, is a serious medical condition that can lead to infection, loss of vision, and damage to the eye globe. Immediate medical attention is necessary.

• Can you see without a cornea?

Without a cornea, vision would be significantly impaired. The cornea is crucial for focusing light onto the retina, and without it, vision may be blurred or absent.

• How do you keep your cornea healthy?

To maintain a healthy cornea, it is important to protect the eyes from injury, practice good hygiene, avoid prolonged contact lens wear, and treat underlying conditions like dry eye or conjunctivitis.

• Does a ruptured eye have to be removed?

Not all ruptured eyes need to be removed, but severe eye trauma may necessitate enucleation if the eye cannot be salvaged. Surgical repair may restore some function in less severe cases.

• Is a ruptured eye painful?

Yes, a ruptured eye is extremely painful, often associated with intense discomfort, swelling, and potential vision loss.

• What is the rupture of the cornea called?

The rupture of the cornea is called a corneal rupture or corneal perforation, depending on the severity of the tear or hole in the tissue.

• Can a cornea grow back?

The cornea has a limited ability to regenerate, particularly for superficial injuries. However, a perforated or ruptured cornea typically requires surgical intervention, such as a corneal transplant, to restore vision.

• Can a damaged cornea cause blindness?

Yes, a severely damaged cornea can lead to blindness if left untreated, especially if the injury causes scarring, infection, or globe rupture.

• How successful is a cornea transplant?

Corneal transplant success rates are generally high, with many patients experiencing significant vision improvement. However, the outcome depends on factors like the cause of damage, the patient's overall health, and the quality of the donor tissue.
