Sample item

Which structure determines resistance to aqueous humour drainage in open-angle glaucoma?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Trabecular meshwork

Aqueous humour drains through the trabecular meshwork into Schlemm canal, and increased outflow resistance can elevate intraocular pressure.

Option by option

  • A. Macula

    Macula provides central retinal vision.

  • B. Trabecular meshwork (correct)

    Correct: trabecular outflow resistance is central to open-angle glaucoma.

  • C. Corneal epithelium

    Corneal epithelium protects the surface but does not drain aqueous.

  • D. Vitreous gel

    Vitreous gel fills the posterior segment.
