Sample item

What is the main mechanism of dry-eye disease in aqueous tear deficiency?

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

The answer and the reasoning

D. Reduced lacrimal tear production

Aqueous-deficient dry eye results from inadequate lacrimal secretion, producing irritation, fluctuating vision, and corneal surface damage.

Option by option

  • A. Increased lens opacity

    Lens opacity is cataract.

  • B. Excess retinal fluid

    Retinal fluid affects posterior segment.

  • C. Loss of vitreous gel

    Vitreous loss is not dry eye.

  • D. Reduced lacrimal tear production (correct)

    Correct: low tear volume causes aqueous deficiency.
