What is microcornea?

What is microcornea?

Definition. A congenital abnormality of the cornea in which the cornea and the anterior segment of the eye are smaller than normal. The horizontal diameter of the cornea does not reach 10 mm even in adulthood. [ from HPO]

What is ocular rosacea?

Ocular rosacea (roe-ZAY-she-uh) is inflammation that causes redness, burning and itching of the eyes. It often develops in people who have rosacea, a chronic skin condition that affects the face.

What is cornea plana?

Cornea plana is an abnormally flat shape of the cornea such that the normal protrusion of the cornea from the sclera is missing. The reduced corneal curvature can lead to hyperopia, and a hazy corneal limbus and arcus lipoides may develop at an early age. [

Can Microcornea be treated?

In conclusion, our study showed that patients with microcornea, persistent fetal vasculature, chorioretinal coloboma, and microphthalmos, can benefit from surgical intervention including PPV, PPL, IVB, and STT.

What is the Microphthalmos?

Microphthalmos also called microphthalmia, is a rare developmental disorder of the eye in which one or both eyes are abnormally small. It may occur as an isolated entity but is commonly associated with other ocular or systemic findings as part of a syndrome.

What is cloudy cornea?

A cloudy cornea is a loss of transparency of the cornea. The eye is the organ of sight, a nearly spherical hollow globe filled with fluids (humors). The outer layer or tunic (sclera, or white, and cornea) is fibrous and protective. The middle layer (choroid, ciliary body and the iris) is vascular.

What is the difference between microphthalmos and nanophthalmos?

Classification. Warburg (1981, 1993) defined nanophthalmos or pure microphthalmos as a developmental arrest of ocular growth not associated with other ocular malformations. Later, it was underscored that nanophthalmos was a form of total microphthalmos, where both anterior and posterior segments are shortened.

Is buphthalmos genetic?

Buphthalmia is inherited as an autosomal recessive trait (bu/bu). It has been suggested that this mutation and resulting loss of appropriate gene function perturbs differentiation of the trabecular meshwork, resulting in the buphthalmic phenotype (Knepper et al., 1997).

What is the most common cause of childhood glaucoma?

Examples of conditions which can be associated with childhood glaucoma include Axenfeld-Reiger Syndrome, aniridia, Sturge-Weber Syndrome, neurofibromatosis, chronic steroid use, trauma, or previous eye surgery such as childhood cataract removal.

Can congenital glaucoma be cured?

Even though congenital glaucoma is not completely reversible, it could be controlled and a complete vision loss could be prevented. You could treat it before it worsens.

What is corneal Leucoma?

The cornea is a transparent tissue that protects the iris, the lens and allows the entry of light from the outside to the inside of the eye. So, the Corneal leucoma is a disorder that causes opacification of the cornea causing visual acuity to decrease significantly .

What is the pathophysiology of Neonatal acne?

Neonatal acne has been attributed to transiently elevated androgens, of either maternal origin and placentally transferred, or neonatal adrenal or testicular androgens. In infantile acne, androgens undeniably play a role in the pathogenesis of the disorder, but their role may be over-emphasized.

What are the signs and symptoms of infantile acne?

The acne may include comedones (whiteheads and blackheads), inflamed papules and pustules, nodules, and cysts. It may result in scarring. See more images of acne in young children. What is the cause of infantile acne? The cause of infantile acne is unknown. It is thought to be genetic in origin.

What is infantile acne and how is it treated?

Individuals with severe infantile acne tend to develop troublesome acne at puberty. What is the treatment for infantile acne? Treatment of infantile acne is usually with topical agents such as benzoyl peroxide or erythromycin gel. In severe cases, oral antibiotics such as erythromycin and trimethoprim, or isotretinoin may be required.
