- 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
