A traumatic separation between the iris root and ciliary body
Is not an uncommon cause of trauma related glaucoma
May be caused by nonpenetrating trauma by blunt object or penetrating injury to the globe
Clinical Features
Symptoms: pain, blurred vision, history of blunt or penetrating trauma
Signs:
Acute phase:
Hyphema and an irregular pupil
Slightly reduced intraocular pressure due to iritis or increased aqueous
outflow through the disrupted structure of the angle
Transient elevated intraocular pressure due to hyphema or anteriorly dislocated lens
May be associated with lens dislocation
Chronic phase:
Chronic pressure elevation due to obstruction of the aqueous outflow system from scarring of the torn ciliary body or from peripheral anterior synechiae
Optic disc cupping
Visual field loss
Management
Topical anti-glaucoma agents in the early postinjury period.
Surgical repair of iridodialysis if patient symptomatic
Filtration surgery (eg, trabeculectomy with antimetabolite therapy) if intraocular pressure uncontrolled medically
