3. Functional alterations
4. Optic Nerve Damage
5. Visual loss

Question 2

Glaucoma: Stages

Precipitating factors include:
- Illness, emotional stress
- Congenital narrow angles
- long-term corticosteroids
- Mydriatic medications causing pupillary dilation

Answer 2

Initiating events

Question 3

Glaucoma: Stages

Tissue and cellular changes caused by factors that affect aqueous humor dynamics lead structural alterations

Answer 3

Structural Alterations in the Aqueous Outflow System

Question 4

Glaucoma: Stages

Conditions such as increased IOP or impaired blood flow create functional changes that lead to the 4th stage

Answer 4

Functional Alterations

Question 5

Glaucoma: Stages

Atrophy of the optic nerve is characterized by loss of nerve fibers and blood supply and this 4th stage inevitably progresses to the 5th stage

Answer 5

Optic Nerve Damage

Question 6

Glaucoma: Stages

Answer 6

Visual loss
