What is anterior lenticonus?

Anterior lenticonus is a rare condition in which the lens presents a conical protrusion of its anterior cortex.

What causes anterior lenticonus?

Anterior conical protrusion of the central lens surface caused by the thinning of affected anterior capsule. Deficiency of the subjacent epithelium resulting in irregular astigmatism. The lens defect may be an isolated finding or more commonly associated with Alport’s syndrome.

How is lenticonus diagnosed?

Lenticonus is a bulging of the lens capsule and the underlying cortex. The diagnosis of lenticonus is essentially a clinical diagnosis which is made by biomicroscopic examination. According to the localization of the conus a distinction is made between lenticonus anterior and lenticonus posterior.

What is Lentiglobus?

[ lĕn′tĭ-glō′bəs ] n. A rare congenital anomaly in which the posterior surface of the lens has a prominent spheroid elevation.

Which type of lenticonus is more common in males?

Posterior lenticonus is more common than anterior lenticonus and is usually unilateral and associated with Lowe’s syndrome, whereas anterior lenticonus, which is often bilateral, may be associated with Alport syndrome.

What are the symptoms of Alport syndrome?

What are the signs and symptoms of Alport syndrome?

• Blood in the urine (hematuria), the most common and earliest sign of Alport syndrome.
• Protein in the urine (proteinuria)
• High blood pressure (hypertension)
• Swelling in the legs, ankle, feet and around the eyes (called edema)

What is Fincham test?

It is a test to determine whether a coloured halo originates from the lens (as in cataract) or from the cornea (as occurs in acute congestive glaucoma). A stenopaeic slit is passed across the pupil.

What is lamellar cataract?

Lamellar or zonular cataract is a hereditary cataract that is transmitted in an autosomal dominant mode. The crystalline opacities are located at the level of the primary fibers in the embryonic nucleus. This cataract is usually bilateral and asymmetrical.

Which is the most common presentation of acute anterior uveitis?

Of these many subsets, the most common presentation for uveitis is undoubtedly acute anterior uveitis or AAU. Anterior means that the front portion of the uvea, the iris and ciliary body, are primarily affected by the inflammation.

Where does posterior lenticonus in the retina occur?

Posterior lenticonus also occurs but is less common. Retina’s injuries are localized in the inner limiting membrane/nerve fiber layer and may interfere with the homeostasis of retinal environment: nutrition of the overlying cells, removal of debris, and maintenance of the watertight barrier.

When to have surgery for acute anterior uveitis?

Surgery is reserved for dealing with the complications of uveitis. Typically intraocular surgery is only performed when the eye has been quiet for 3 months. AAU may have complications such as the formation of posterior synechiae, band keratopathy or a rise in intraocular pressure, which may lead to glaucoma.

What does the anterior part of the uvea mean?

Anterior means that the front portion of the uvea, the iris and ciliary body, are primarily affected by the inflammation. The anterior part of the uvea is the iris that surrounds the pupil and the adjacent ciliary body that synthesizes aqueous humor, the fluid that fills the front of the eye.
