What are the types of lens induced glaucoma?
Different types of Lens Induced Glaucoma are
- Phacolytic glaucoma.
- Phacomorphic glaucoma.
- Lens particle glaucoma.
- Phacotopic glaucoma.
- Phacoanaphylatic uveitis with secondary glaucoma.
WHAT IS lens induced glaucoma?
Lens-induced glaucoma is a secondary glaucoma in which the crystalline lens is involved in the mechanism of intraocular pressure (IOP) increase. The glaucoma may occur in open-angle or angle-closure forms, and there are 4 distinct variants: phacolytic, lens-particle, phacoantigenic, and phacomorphic.
What are the 4 types of glaucoma?
There are several types of glaucoma. The two main types are open-angle and angle-closure….Other Types of Glaucoma
- Secondary Glaucoma.
- Pigmentary Glaucoma.
- Pseudoexfoliative Glaucoma.
- Traumatic Glaucoma.
- Neovascular Glaucoma.
- Irido Corneal Endothelial Syndrome (ICE)
- Uveitic Glaucoma.
What is the most common mechanism for angle closure?
Pupillary block due to pupil dilatation is the most common mechanism of angle closure. It occurs when the pupil comes into contact with the lens and obstructs the aqueous flow from the posterior chamber to the anterior chamber.
What is the use of crystalline lens?
The crystalline lens of the eye is a natural lens which produces one third of the eye’s total optical power and focuses light into an image on the retina (the light-sensitive tissue at the back of the eye). The crystalline lens is elastic which allows it to flex in order to change its shape.
What is Angle-Closure Glaucoma?
Angle-closure glaucoma, also called closed-angle glaucoma, occurs when the iris bulges forward to narrow or block the drainage angle formed by the cornea and iris. As a result, fluid can’t circulate through the eye and pressure increases.
Does cataract lead to glaucoma?
Cataracts do not typically lead to glaucoma, however there are many shared risk factors and the two conditions may be discovered at the same time. The reverse is also true, glaucoma does not lead to cataracts. However, there are rare conditions in which glaucoma treatment may accelerate cataract development.
Which is more serious open or closed-angle glaucoma?
It’s the leading cause of irreversible blindness. Closed-angle (or angle-closure) glaucoma makes up less than 20 percent of glaucoma cases in the United States. It’s usually more severe than open-angle glaucoma. Both conditions involve changes in the eye that prevent proper drainage of fluid.
Can you have both open and closed-angle glaucoma?
Congenital glaucoma, a type of childhood glaucoma, occurs in children born with defects in the angle of the eye that slow the normal drainage of fluid. Prompt medical treatment is important in preventing blindness. Both open-angle and angle-closure glaucoma can be classified as primary or secondary.
Which is worse open or closed-angle glaucoma?
