How is Phacolytic glaucoma treated?
The definitive treatment of phacolytic glaucoma (PG) is cataract extraction. Extracapsular cataract extraction (eg, phacoemulsification) with an intraocular lens implant has largely replaced intracapsular cataract extraction as the procedure of choice.
What is the principal mechanism of Phacolytic glaucoma?
Phacolytic glaucoma is caused by an inflammatory process caused by the leakage of lens material through the capsule of a mature cataract. The released lens material is composed of altered lens protein, macrophages, and other inflammatory cells that lead to trabecular meshwork obstruction and precipitate glaucoma.
What is a Phacomorphic glaucoma?
Phacomorphic glaucoma is the term used for secondary angle-closure glaucoma due to lens intumescence. The increase in lens thickness from an advanced cataract, a rapidly intumescent lens, or a traumatic cataract can lead to pupillary block and angle closure.
Can a hypermature cataract cause glaucoma?
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.
What is a Morgagnian cataract?
A morgagnian cataract is a hypermature cataract in which the total liquefaction of the cortex has allowed the nucleus to sink inferiorly. 1. Herein, we report a rare case of morgagnian cataract with an isolated posterior opening with no history of trauma and its successful management.
What is hypermature cataract?
A hypermature cataract becomes white when degenerating cortex reaches a hyperosmotic state inside the capsule and draws in fluid. This process leaves a very tense capsule and a heavy nucleus that often sinks in the gelatinous and fluid cortex (Morgagnian cataract).
What is Pseudoexfoliation glaucoma?
Pseudoexfoliation glaucoma, or pseudoexfoliative glaucoma, is the same condition with the addition of elevated eye pressure and evidence of damage to the optic nerve. Pseudoexfoliation is not to be confused with “true exfoliation”, which is due to heat or infrared exposure (and which can be found among glassblowers).
How can you tell Morgagnian cataracts?
- Blurring of vision and glare may be early signs of developing cataract.
- Morgagnian cataracts will typically present with profound visual loss (hand-motions or light-perception)
Why is it called Morgagnian cataract?
Morgagnian cataract (MC), named after the Italian anatomist anatomist, Giovanni B. Morgagni, is a cataract in which there is liquefaction of the cortex and sinking of the dense nucleus in the capsular bag.
