Cataracts from Radiant Energy/Medications

Question 1

Describe infra-red cataracts (Glass blowers cataract)

How does it occur, what happens to the lens

Answer 1

• Iris absorbs heat and transfers to lens, “cooking the albumoids”
• Lens turns white, capsules exfloriates, splits and curls up in anterior chamber

Question 2

Describe X-ray, gamma ray cataracts

How long after onset does cataract occur and how does radiation cause cataract?

Answer 2

• cataracts develops 1-2 years

- interferes with dividing cells at equator of lens

Question 3

Describe cataracts related to eletric shock

what type of cataract develops?

Answer 3

• cortical cataract from heat, concussion or electrolytic dissociation

Question 4

What type of cataract can develop from steroids and phenothiazines (psychological disorders)

Answer 4

• Steriods: develop PSC

- Phenothiazines: sevelop stellated supcapsular cataracts

Question 5

You have a patient that presents with a white lens with the capsule exfoliated, split and curled up in anterior chamber. What is the cause of the cataract?

A. Infra-red
B. X-ray/Gamma Ray
C. Electric Shock
D. Steroids
E. Phenothiazines

Answer 5

A. Infra-red

Question 6

You have a patient that presents with a PSC. Which could cause of the cataract?

A. Infra-red
B. X-ray/Gamma Ray

Question 7

You have a patient that presents with a cortical cataract. Which could cause of the cataract?

A. Infra-red
B. X-ray/Gamma Ray
C. Electric Shock
D. Steroids
E. Phenothiazines

Answer 7

Question 8

You have a patient that presents with a stellated subcapsular cataract. Which could cause of the cataract?

A. Infra-red
B. X-ray/Gamma Ray
C. Electric Shock
D. Steroids
E. Phenothiazines

Answer 8

E. Phenothiazines

Question 9

You have a patient that presents with a cataract caused by interference with dividing cells at lens equator. Which could cause of the cataract?

A. Infra-red
B. X-ray/Gamma Ray
C. Electric Shock
D. Steroids
E. Phenothiazines

Answer 9

B. X-ray/Gamma Ray

C. Stellated subcapsular cataracts
D. Cataracts develop from interference with dividing cells at equator
E. Cortical Cataracts

Answer 10
