Ocular collapse can be caused by which condition?

Explanation:
Ocular collapse happens when the globe loses enough intraocular pressure due to a breach in its wall. A perforating injury that leaks aqueous humor and vitreous fluid causes rapid hypotony, leading to the eye collapsing. This mechanism fits best with how collapse occurs—through loss of containment of the eye’s fluids after damage. Glaucoma raises pressure rather than causing collapse, uveitis can cause hypotony in severe cases but not through leaking from a perforation, and cataract changes the lens without compromising globe integrity.
