Test: Cornea - 1 - NEET PG MCQ

Natamycin is highly effective against Aspergillus fumigatus and various other hyphal fungi.

All corneal dystrophies are inherited in an autosomal dominant manner, with the exception of macular dystrophy.

The sensory innervation of the eye is provided by the trigeminal nerve.

In keratoconus, the corneal nerves appear more prominent as a result of corneal thinning rather than an increase in the thickness of the corneal nerves.

The use of contact lenses reduces the oxygen availability to the cornea, which impacts the utilisation of glucose rather than the supply of glucose itself.

Golden brown discolouration represents the Kayser-Fleischer ring observed in individuals with Wilson’s disease.

Corneal ulcers, regardless of whether they are fungal or arise from other causes, may impact the uvea, leading to related uveitis. Therefore, Atropine is administered.

Snow blindness, also referred to as photophthalmia, is a form of UV damage to the eye. It results in the erosion of the corneal epithelium.

A distinctive characteristic of viral keratitis is a reduction in corneal sensitivity.

Steroids are not recommended in cases of any infectious conditions affecting the cornea.

Satellite nodules are tiny lesions located apart from the primary ulcer. This is a characteristic associated with fungal corneal ulcers.

Moisture in any layer of the cornea is the key element in reducing its transparency.

The initiation of anaerobic glycolysis results in the build-up of lactic acid, which triggers metabolic acidosis. This condition subsequently inhibits the function of the endothelium pump.

Band-shaped keratopathy refers to the buildup of calcium on the corneal surface.

The cornea from a donor is sourced from deceased individuals' eyes.

Herpes zoster is identified by:

• skin lesions
• eye lesions
• trigeminal neuralgia

Fungal corneal ulcers are frequently seen in farmers and typically arise from injuries caused by organic materials.

Squamous blepharitis does not contribute to the likelihood of developing Acanthamoeba keratitis. It arises from the presence of dandruff on the scalp.

Aspergillus fumigatus is the most prevalent fungus causing infections in the cornea in India.

Recurrent corneal erosion is a characteristic of epithelial corneal dystrophy.

Corneal vascularisation is not characteristic of corneal dystrophies. Corneal dystrophy represents an idiopathic, spontaneous alteration that lacks any inflammatory aspect.

In fungal corneal ulcers, the indications are more significant than the symptoms.

Vernal keratitis is defined by the presence of a papillary response, while lacking any follicular reaction.
