Test: Glaucoma - 3 - NEET PG MCQ

OAG appears as an arcuate scotoma. The expansion of the blind spot is a characteristic of papilloedema.

Coloured halos result from corneal oedema, an epithelial swelling that arises from an acute increase in intraocular pressure (IOP).

Cyclopentolate is not a medication used for treating glaucoma. It functions as a mydriatic agent with cycloplegic properties.

In cavernous optic atrophy, alongside the damage to the nerve fibres, there is also degeneration of the glial tissue (resulting from insufficient blood supply), which leads to the development of large caverns or lacunae.

Central field charting is referred to as Campimetry.

Synechiae refer to adhesions and are a characteristic of uveitis.

The pH of aqueous humour is 7.2. This indicates that it is acidic in comparison to plasma.

Aqueous is produced from the non-pigmented epithelium of the ciliary processes.

Pupil is vertically oval and mid-dilated in cases of acute angle closure glaucoma.

Phacomorphic glaucoma results in a pupillary block, which subsequently leads to angle-closure glaucoma.

Steroid-induced glaucoma is classified as open-angle glaucoma. The anterior chamber (AC) depth remains within the normal range.

Ninety per cent of glaucomas are classified as open-angle glaucomas. Consequently, the true ratio is 9:1.

Gonioscopy is a bimicroscopic assessment of the angle within the anterior chamber.

The iris seals a corneal perforation, resulting in anterior synechiae, which may lead to angle closure.

NVG in central retinal vein occlusion is referred to as 100-day glaucoma.

The combination of miotic and mydriatic agents results in a mid-dilation of the pupil, and the risk of angle closure is greatest when the pupil is mid-dilated. Therefore, this condition is considered the most dependable.

Goniotomy is performed when the pupil is narrowed.

Laser trabeculoplasty is chosen for open-angle glaucoma when the patient does not respond to medical treatment.

It signifies a phase of ongoing unpredictability.

Pilocarpine reduces the uveoscleral outflow, while prostaglandin analogues enhance the flow.

Congenital cataracts and obstruction of the nasolacrimal duct do not typically manifest as photophobia.

Choroidal detachment may arise as a complication of trabeculectomy resulting from hypotony; however, it does not occur due to choroidal degenerations.

Schwalbe’s line is the foremost structure visible during gonioscopy.

The typical value of C:D is less than 0.3.
