Types Of Corneal Opacity

What Is Corneal Opacity?

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). Injury, infection, and certain eye diseases can cause corneal opacities.

Types Of Corneal Opacity

Depending on the density, corneal opacity is graded as nebula, macula and leucoma.

Nebular Corneal Opacity

It is a faint opacity which results due to superficial scars involving Bowman's layer and superficial stroma. A nebular corneal opacity allows the details of the iris to be seen through the opacity. A thin, diffuse nebula covering the pupillary area interferes more with vision than a strictly localized dense leucoma, so long as the latter does not block the whole pupillary area. This is because the leucoma stops all the light which falls upon it, whereas the nebula refracts it irregularly, allowing many of the rays to fall upon the retina where they blur the image formed by the regularly refracted rays.

Macular Corneal Opacity

It is a semi-dense opacity produced when scarring involves about half the corneal stroma.

Leucomatous Corneal Opacity (Leucoma Simplex)

It is a dense white opacity which results due to scarring of more than half of the stroma

. Adherent leucoma: It results when healing occurs after perforation of cornea with incarceration of iris. The iris is adherent to the back of a leucomatous cornea. One of the major complications of adherent leucoma is Secondary glaucoma

. Corneoiridic scar: If iris tissue is incarcerated and incorporated within the scar tissue, as occurs in healing of a large sloughed corneal ulcer, it is called a corneoiridic scar.

. Corneal facet: Sometimes the corneal surface is depressed at the site of healing (due to less fibrous tissue); such a scar is called facet.

. Kerectasia: In this condition, corneal curvature is increased at the site of opacity (bulge due to weak scar).

10 common question about corneal opacity surgery

1How do you treat corneal opacity?
Depending on the cause, treatment for corneal infections may include: Antibiotic, antibacterial, antifungal, or steroidal eye drops. Topical or oral antiviral medication. Phototherapeutic keratectomy (laser surgery) Corneal transplant.
2What causes cloudy cornea?
Causes. Corneal haze is most often appears after suffering a trauma, infection or surgery. It is usually caused by inflammatory cells and other debris that is activated inside the eye. Corneal haze also sometimes occurs during laser vision correction procedures.
3Which drug causes corneal opacity?
A number of systemic agents can cause corneal depositions (cornea verticillata). ... Other systemic drugs that may cause corneal disorders, including ulcers and perforations, are oncolytics (e.g. cytarabine and epidermal growth factor receptor (EGFR) inhibitors), isotretinoin, nicorandil, NSAIDs and rifabutin.
4What happens if cornea is damaged?
The cornea is your eye's clear, protective outer layer. ... If your cornea is damaged by disease, infection, or an injury, the resulting scars can affect your vision. They might block or distort light as it enters your eye.
5What is the white opacity in the cornea?
Corneal opacity is a disorder of the cornea. The cornea is the transparent structure on the front of the eyeball. Corneal opacity occurs when the cornea becomes scarred. This stops light from passing through the cornea to the retina and may cause the cornea to appear white or clouded over.
6What causes corneal opacity?
Congenital corneal opacities are most commonly caused by a malformation of the anterior segment of the eye (anterior segment dysgenesis) but additional causes include congenital glaucoma (Figure 1), dermoid, trauma, infection, corneal dystrophies, and metabolic storage diseases.
7Why is my vision suddenly cloudy in one eye?
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, but blurry and cloudy vision can both be symptoms of a serious eye problem
8How long does it take for a cornea to heal?
Treatments for a Scratched Eye Superficial corneal abrasions tend to heal quickly, usually within two or three days. But other corneal abrasions may require an antibiotic ointment that stays on the eye longer, a steroid to decrease inflammation and scarring, and something to relieve pain and light sensitivity.
9How 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.
10Can corneal ulcer cause blindness?
Otherwise, untreated corneal ulcers can lead to severe vision loss and even loss of the eye. ... In most cases of this type of corneal ulcer, the eye already is compromised by pre-existing conditions, such as an immune disorder.
