Test: Cornea - 2 - NEET PG MCQ

In leprosy, there is a thickening of the nerves, while in keratoconus, the cornea experiences thinning.

The corneal epithelium consists of multiple layers of columnar cells that are non-keratinised.

H₂O is more prevalent among patients with weakened immune systems.

Additional antiviral agents include: Trifluorothymidine and Adenine Arabinoside.

Ophthalmia neonatorum refers to any form of conjunctivitis that occurs within the first month after birth.

Keratoconus is characterised by a conical bulge of both the anterior and posterior surfaces of the cornea.

Organisms capable of invading the typical cornea include:

• chlamydia
• gonorrhoea
• haemophilus
• listeria

Steroids are not recommended for use in dendritic ulcers.

• Oral treatment is unnecessary for simplex infections;
• however, it is essential for zoster infections.

Photophthalmia manifests as erosions of the corneal epithelium and is managed through the application of a pad and bandage along with antibiotic ointment.

Protrusion of the cornea will result in myopia rather than hypermetropia.

Both the cornea and lens are structures of the eye that lack blood vessels.

The thickness of the cornea is assessed using pachymetry, while the refractive power is evaluated through retinoscopy.

Brown skin cornea refers to the brown discolouration of the cornea. This condition arises from the accumulation of gold and silver, and it can also manifest in cases of oculodermal melanocytosis.

Pneumococcus is responsible for causing hypopyon corneal ulcer.

KCS is a condition of dry eye resulting from a deficiency in the aqueous layer. It is typically linked to disorders of the connective tissue.

Fluid-filled bullae develop on the epithelial surface of the cornea as a result of endothelial dysfunction.

The corneal endothelium is examined using specular microscopy.

Herpes simplex occurs more frequently than Herpes zoster.

The discomfort associated with acanthamoeba keratitis is significantly heightened as a result of perineural invasion.

Signs represent more than just symptoms in fungal ulcers.

Corneal curvature is assessed using both corneal topography and keratometry.

The eye should never be covered or patched with tarsorrhaphy in cases of infectious conditions.

Pus cells present in the anterior chamber are referred to as hypopyon, while the presence of blood in the anterior chamber is termed hyphema.

In fungal keratitis, clinical signs are more pronounced than symptoms.
