- A form of lens-induced open-angle glaucoma.
- Caused by the leakage of lens protein (from a mature or hypermature cataract) into the aqueous humor, thereby causing obstruction of aqueous outflow.
- Symptoms: may present as sudden or insidious onset of ocular pain and worsened vision
- Occurs unilaterally (majority of cases)
- Conjunctival hyperemia (associated)
- Acutely elevated intraocular pressure (may reach as high as 80 mmHg)
- Diffuse corneal edema
- Inflammatory cells in the anterior chamber
- Presence of white patches on the anterior lens capsule probably representing phagocytosis of lens protein by macrophages
- On gonioscopy evaluation, the anterior chamber angle appears open
- Anti-inflammatory therapy
- Anti-glaucoma medication(s)
- Cataract removal surgery (the IOP usually returns to normal in several days)
