What causes 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. Phacomorphic glaucoma.
Is glaucoma a comorbidity?
Distribution of secondary glaucoma types The most common associated systematic comorbidities among patients diagnosed with glaucoma were hypertension (60.8%), diabetes (58.3%), obesity (43.1%), and dyslipidemia (33.6%). Cataract (49.1%) was the most prevalent associated ocular comorbidity.
What are the potential problems of operating on an eye with Phacomorphic glaucoma?
Phacomorphic glaucoma can have a component of primary pupillary block and a secondary angle-closure mechanism. Patients with this condition may present with decreased vision, eye pain, and headache—much as in primary angle-closure glaucoma.
What are the preventive measures and treatment for glaucoma?
Prevention
- Get regular dilated eye examinations. Regular comprehensive eye exams can help detect glaucoma in its early stages, before significant damage occurs.
- Know your family’s eye health history. Glaucoma tends to run in families.
- Exercise safely.
- Take prescribed eyedrops regularly.
- Wear eye protection.
Is glaucoma high risk for Covid?
However, glaucoma patients are typically of older age and have underlying medical issues, making them susceptible to serious illness from the coronavirus.
How does Covid 19 Affect glaucoma?
The impact of the Covid-19 pandemic has accelerated the worsening of glaucoma cases in people who had already been previously diagnosed, which, in some situations, has caused them to lose their visual acuity, which is irretrievable.
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).
What is the pathophysiology of phacomorphic glaucoma?
Pathophysiology. Phacomorphic glaucoma is a lens-induced secondary angle-closure glaucoma that may occur as a result of mature cataract formation. Narrowing of the angle can occur slowly with formation of the cataract by pushing the iris forward or acutely precipitated by an intumescent cataractous lens leading to obstruction…
What is phacoantigenic glaucoma?
Phacoantigenic glaucoma is a granulomatous inflammatory reaction directed against own lens antigens leading to obstruction of the trabecular meshwork and increased intraocular pressure. It is important to mention that phacoanaphylaxis is not the correct name of this condition since it is not an allergy.
What is phacomorphic glaucoma (pupillary block)?
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. Phacomorphic glaucoma is shown in the image below. Phacomorphic glaucoma.
What causes secondary angle-closure glaucoma?
Secondary angle-closure glaucoma may occur if the lens is displaced from its normal anatomical position (Ectopia lentis). Forward displacement of the lens may result in narrowing of the anterior chamber angle and pupillary block causing secondary angle-closure.
