Test: Glaucoma - 2 - NEET PG MCQ

A notable side effect of Epinephrine is cystoid macular oedema; therefore, it should be avoided in individuals without a natural lens.

Buphthalmos refers to the swelling of the eyeball, which is typically linked to an enlarged cornea. The management of buphthalmos involves a procedure known as Goniotomy.

In buphthalmos, there is an increase in tear production, known as lacrimation. In contrast, epiphora arises when the drainage system for tears is obstructed.

A large cornea in buphthalmos serves as a differential diagnosis for megalocornea.

Fluoromethalones have the minimal impact on intraocular pressure (IOP).

Laser iridotomy must consistently be performed as a preventive measure in the opposite eye as well.

The rate at which aqueous humour is produced is 2.3 µl/min. The typical pressure range is 10–21 mm Hg.

A rupture in the Descemet's membrane resulting from excessive stretching of the cornea in individuals with buphthalmos is referred to as Haab’s striae.

Malignant glaucoma, known as ciliary-block glaucoma, arises following any intraocular surgical procedure. In this situation, aqueous humour begins to accumulate in the vitreous cavity.

A middle-aged woman with a history of a painful red eye, accompanied by nausea and vomiting – the most likely diagnosis is angle closure glaucoma.

Pilocarpine worsens inflammation and is not administered to individuals experiencing uveitis.

Open angle glaucoma is a subtle condition, and as a result, a sudden increase in pressure is typically not observed. Consequently, there is no corneal swelling, which is a factor that leads to coloured halos in angle closure glaucoma.

In buphthalmos, the expansion of the cornea results in an enlarged cornea.

Enlargement of the eyeball results in the lens being stretched, causing it to become flat. In the subsequent stage, this stretching may rupture the zonules, resulting in the subluxation of the lens.

Malignant glaucoma is managed with a mydriatic agent, such as Atropine. Therefore, it is also referred to as INVERSE glaucoma.

Atropine is not classified as an antiglaucoma medication and does not influence the production or outflow of the aqueous humour.

It is an oval channel lined by endothelium, located circumferentially within the scleral sulcus. The endothelium of the inner wall is irregular and features large vacuoles, while the outer wall has smooth endothelial cells that include the entrances of the collector channels.

Betaxolol is a selective α-blocker and is suitable for use in patients with asthma.

Normal intraocular pressure (IOP) ranges from 10 to 21 mm Hg.

Scleral rigidity may influence IOP measurements when assessed using indentation methods, such as the Schiotz tonometer. However, it does not impact readings taken through applanation techniques.

Pthisis bulbi refers to the reduction in the size of the eyeball, which results in a lowered intraocular pressure (IOP).
