Flashcards in Lens Deck (12):
1

Hardening of the lens that occurs naturally in animals. The hardening scatters light such that the lens appears cloudy. Does not cause vision loss.

Nuclear Sclerosis

2

any opacity of the lens or lens capsule

Cataract

3

Utilizing the appearance of one object relative to another to determine depth

Parallax

4

Small collagen fibrils arising from the ciliary body that attach to the equator of the lens, securing the lens' position within the eye

Lens Zonules

5

Type of cataract is common in diabetics in which the cataract progression is driven by an osmotic effect as a result of entrapped sorbitol within the lens capsule

Intumescent (swollen) cataracts

6

This is the modern technique for cataract surgery in which the lens is broken up using ultrasound energy and aspiration.

Phacoemulsification

7

enzyme that converts glucose to sorbitol which becomes trapped within the lens capsule, causing an osmotic pulling effect.. Lens swells creating an intumescent cataract.

Aldose reductase

8

Complete detachment of the lens from the lens zonules. the lens typically shifts anteriorly or posteriorly

Lens Luxation

9

Partial detachment of the lens from the lens zonules. The lens typically shifts side to side revealing an aphakic crescent.

Lens subluxation

10

Meaning without a lens; lens subluxation displays a crescent shaped area in which the lens is visibly displaced, known as an aphakic crescent.

Aphakic crescent

11

Movement of the iris that occurs secondary to lens instability

Iridodonesis

12

Movement of the lens that occurs secondary to lens instability.

Phacodonesis
