Abnormalities of the anterior chamber

Question 1

The accumulation of pus (white blood cells) in the anterior chamber is known as

Answer 1

Hypopyon

Question 2

The pooling of blood in the anterior chamber as a result of trauma or disease is

Answer 2

Hyphema

Question 3

An eye disease in which the IOP is high enough to cause damage to the optic nerve, resulting in visual loss; caused by impaired drainage of the aqueous fluid out of the eye

Answer 3

Glaucoma

Question 4

How is glaucoma diagnosed?

Answer 4

measurement of IOP, the patient’s visual field, corneal thickness, and examination of the optic nerve head.

Question 5

An instrument that measures the distance between the corneal epithelium and the corneal endothelium is called a _________. Corneal thickness is a risk factor for glaucoma

Answer 5

Pachymeter

Question 6

What are the 4 main types of glaucoma?

Answer 6

primary open-angle (or chronic open-angle), primary angle-closure (or primary closed-angle), secondary (open and closed), and congenital (developmental)

Question 7

A form of glaucoma in which the pressure inside the eye is elevated because of increased resistance to aqueous drainage in the outflow channels; accounting for 60-90% of all adult glaucoma

Answer 7

Primary open-angle glaucoma

Question 8

A form of glaucoma associated with a structural abnormality of the eye resulting in a shallow anterior chamber angle; also as the lens increases in size with aging, it blocks the flow of aqueous through the pupil, gradually causing the iris to bow forward until its outer edge blocks the aqueous outflow channels

Answer 8

Primary angle-closure glaucoma

Question 9

Glaucoma that occurs secondary to another, primary disease

Answer 9

Secondary glaucoma

Question 10

A rare disease that occurs in infants; due to a malformation of the anterior chamber angle

Answer 10

Congenital glaucoma
