Spectrum of condition • Peripheral iris moves forward • to block the trabecular meshwork • Causing a rise of intraocular pressure
Occurs in • short eye • Small corneal diameter • Shallow anterior chamber • Relative anterior positioning of lens iris diaphragm
Forward bowing of peripheral iris Closure of trabecular meshwork
Diagnosis • Goniscopy

Presentation • Sub acute • Acute • Chronic
subacute • Sub acute- sharp rise in intraocular pressure for a short period • Repeated attack • Damage TM • Chronically raised IOP
Acute congestive glaucoma • Sudden rise in intraocular pressure to extremely high level • Unilateral headche, nausea • Marked diminution of vision,coloured halos
Acute congestive glaucoma • Visual acuity- reduced to counting fingers • Lid- edema • Conjunctiva Circumcorneal congestion • Corneal -edema • AC-Shallow anterior chamber Cells and flare
Acute congestive glaucoma • Pupil-Mid dilated pupil,non reactive • Lens- anterior subcapsular opacities • Optic disc- acute- edema,hyperaemic • 2-4 weeks- optic disc cupping • Goinioscopy- appositional closure with or withour peripheral anterirosynechiae
Acute congestive glaucoma • Optic disc- acute- edema, hyperaemic • Optic disc-2-4 weeks- optic disc cupping • Gonioscopy- appositional closure with or without peripheral anterior synechiae • IOP- very high 40mmHg
Treatment • Bring down the IOP- Hyperosmoticagnets • After reducing IOP • Gonioscopy • Laser iridotomy/Trabeculectomy • Prophylactic Laser iridotomy in the other eye
