Corneal Opacities: eye disorders that can cause vision loss

Corneal opacities are eye problems that can lead to scarring or clouding of the cornea, which decreases vision.

The cornea is the clear, dome-shaped area that covers the front of the eye. Light passes through the cornea before reaching the retina in the back of the eye, and so it must remain clear so light can pass through. Corneal opacities can cause anything from minor irritation to vision problems and even blindness. In fact, corneal problems are the fourth leading cause of blindness (after glaucoma, cataracts, and age-related macular degeneration).

Corneal Opacity Symptoms

The cornea is formed by strong, tough tissue composed of five different layers, each with a specific function. The cornea protects the eye from dust, germs, UV rays, and other foreign substances. Along with the lens, it bends light rays onto the retina so that images appear in focus. If the corneal shape is excessively steep, flat, or not completely round, it can cause nearsightedness, farsightedness, or astigmatism. These are called refractive errors. Certain types of corneal diseases can change the shape of the cornea.

Depending on the cause, symptoms of corneal damage may include:

  • Redness and swelling of the eye tissues and eyelid
  • Tearing
  • Blurred vision
  • Irritation
  • Sensitivity to light
  • Sensation of something in the eye
  • Eye discharge
  • Milky or cloudy area on the cornea
  • Vision loss

Corneal injuries cause

Corneal injuries can occur when a foreign object gets in the eye or from something striking the eye. This can cause cuts or scratches to the cornea. Common causes of cornea injury include:

  • Chemical irritation
  • An object in the eye, such as sand or dust
  • Something striking the eye, such as a tree branch
  • Radiation injury from the sun, sun lamps, welding, or sun reflected on snow (snow blindness)
  • Complications of contact lens wear

Cornea infection cause

Corneal infection, also called keratitis, is relatively rare. Several conditions can cause an infection of the cornea, including:

  • Conjunctivitis (pinkeye). Bacteria, viruses, or allergies can cause conjunctivitis. The condition usually causes only minor eye irritation. However, if it becomes severe or remains untreated, it can lead to corneal infection.
  • Herpes zoster (shingles). This infection is caused by the same virus that causes chickenpox. In some people, the infection becomes active again later in life, causing a painful, blistering rash called shingles. Shingles that develop on the face, head, or neck can also affect the cornea. Forty percent of people who get shingles in those areas will develop it on the cornea.
  • Ocular herpes. Herpes of the eye is caused by the herpes simplex virus, the same virus that causes oral and genital herpes. Ocular herpes develops on the eyelid or surface of the eye and can lead to corneal inflammation. This virus is the most common eye infection that causes blindness in the U.S.

Other conditions that cause corneal opacities

Other eye problems and disorders can also lead to corneal opacity, including:

  • Iridocorneal endothelial syndrome, a condition that affects both the iris and cornea, usually only in one eye. It also causes glaucoma, which can be treated with medication.
  • Pterygium, a red vascular growth of tissue on the cornea.
  • Stevens-Johnson syndrome, a serious skindisorder that also can affect the eyes.

Corneal opacity risk factors  

Factors that may increase your chance of corneal opacity:

  • Vitamin A deficiency
  • Measles — when measles result in scarring/infection of the eye
  • Foreign bodies striking the eye
  • Eye injury, whether from a force, such as a poke in the eye, or from a chemical agent
  • Herpes simplex virus — which can be transmitted to the eyes
  • Other infections, including conjunctivitis
  • Wearing contact lenses for a long period of time, especially overnight, can increase the risk of eye infections and also the chance of developing corneal opacity.
  • Keratoconus
  • Stevens-Johnson syndrome
  • Congenital corneal abnormalities

Corneal opacities prevention 

Although corneal opacities have many causes, there are a few things you can do to help prevent damage to your cornea:

Wear protective eyewear. Protect your eyes with goggles or safety glasses during activities that can cause eye injury. This includes using power tools, chopping wood, or handling chemicals. Also be sure to wear sunglasses when spending time outdoors. Make sure your children also wear sunglasses.

Use contact lenses correctly. Follow your eye doctor's instructions for properly handling, storing, disinfecting, and discarding and replacing soft contact lenses.

Have regular eye exams. Many eye conditions can be detected early, before symptoms develop. Also be sure to see your eye doctor right away if you injure your eye or develop any unusual eye symptoms or vision problems.

Know your family history for eye diseases. Because corneal dystrophies are hereditary, you may be at risk if someone in your family has eye disease.

Corneal opacity treatment

Treatments vary depending on the most likely cause and severity of the scarring. Options include:

  • Eye drops containing antibiotics, steroids or both
  • Oral medications
  • Phototherapeutic keratectomy (PTK), laser surgery

Phototherapeutic keratectomy (PTK) involves treating anterior corneal lesions by superficial corneal ablation using an excimer laser (193 nm). Some of the commonly treated conditions include recurrent corneal erosions (RCE), corneal dystrophies, spheroidal degeneration, keratoconus, and corneal scars. 

  • Cornea transplant

A cornea transplant (keratoplasty) is a surgical procedure to replace part of your cornea with corneal tissue from a donor. Your cornea is the transparent, dome-shaped surface of your eye. It's where light enters your eye and is a large part of your eye's ability to see clearly. A cornea transplant can restore vision, reduce pain, and improve the appearance of a damaged or diseased cornea.

Types of corneal opacity

The three grades of the corneal opacities are (i) nebular (ii) macular and (iii) leucoma.

The three words - all from the Latin - nebula, macula, and leukoma are the words used to describe the appearance of a corneal scar. Nebula (fog or mist) describes a hard-to-see corneal scar - one where slit-lamp detection is required. Macula (stain or spot) is typified by the scar in the photo. It can be seen with proper illumination. Leucoma (white) is a white scar that is easily seen just by looking at the eye.

10 common question about Treatment of Corneal Opacity

1What causes corneal opacity?
Corneal opacity is when the cornea becomes scarred. This reduces the light passing through the cornea to the retina and may cause the cornea to appear white or clouded over.
2Can corneal haze be corrected?
Treatment. When corneal haze appears after surgery or other wounds, it will usually disappear as the eye heals. In more severe cases, a doctor may prescribe eye drops or other medication. ... Corneal haze is usually successfully treated in post-laser surgery patients with steroid eye drops.
3Does corneal dystrophy cause blindness?
Corneal dystrophies usually affect both eyes and can cause vision loss and blindness. Sometimes they cause no symptoms and are only discovered during an eye exam. Here are a few of the more common types of corneal dystrophies: Fuchs' dystrophy progresses slowly, usually affecting people in their 50s and 60s.
4How long does a cloudy cornea take to heal?
Superficial corneal abrasions tend to heal quickly — usually within two or three days. Some corneal abrasions may require an antibiotic ointment that stays on the eye longer, a steroid to decrease inflammation, and something to relieve pain and light sensitivity.
5Can damaged corneas be repaired?
With its ability for quick repair, the cornea usually heals after most injury or disease. However, when there is deep injury to the cornea, the healing process may be prolonged, possibly resulting in a variety of symptoms, including: Pain. Blurred vision.
6Can a damaged cornea repair itself?
After minor injuries or scratches, the cornea usually heals on its own. Deeper injuries can cause corneal scarring, resulting in a haze on the cornea that impairs vision.
7How long does it take for corneal epithelium to regenerate?
approximately seven to 10 days The entire epithelium is turned over in approximately seven to 10 days. This process is accelerated during wound healing and generally leads to rapid healing for corneal injuries that only involve the epithelial cells. (See, “A Closer Look: The Corneal Epithelium”).
8Is corneal edema curable?
Corneal edema can be transient and resolve itself after few weeks or months, without treatment. But chronic edema may be resolved only after corneal transplantation. ... This may be a bridge to a cure in the case of transient patients or to cornea transplantation in the case of chronic patients.
9Why is my vision foggy?
The primary causes of blurred vision are refractive errors — nearsightedness, farsightedness and astigmatism — or presbyopia. ... Cloudy vision usually is a symptom of specific conditions such as cataracts. Blurry vision and cloudy vision both can be symptoms of a serious eye problem, especially if they occur suddenly.
10How can corneal blindness be cured?
Corneal infections, inflammatory disease, and trauma, can be treated or prevented in order to minimise scarring and prevent blindness. However, other conditions, such as keratoconus, or hereditary corneal dystrophies, cannot be prevented, and require long term treatment, such as corneal transplants.
