Answer

Shallower anterior chambers; anteriorly situated lens; shorter axial eye length; thick iris; overdeveloped iris dilator muscles; and a narrow angle lead to a higher propensity for development of AACG.

Precipitating factors include drugs (ie, sympathomimetics, anticholinergics, antidepressants [SSRIs], anticonvulsants, sulfonamides, cocaine, botulinum toxin), [10, 11, 12, 13, 14] dim light, and rapid correction of hyperglycemia.

Case reports have identified AACG associated with carotid-cavernous sinus fistula, trauma, prone surgical positioning, and giant cell arteritis. [14, 15, 16]
