Cataract

Question 1

Vision-impairing disease characterized by thickening of the lens:

Answer 1

Cataract

Question 2

Is an age-related vision-impairing disease characterized by gradual progressive thickening of the lens of the eye:

Answer 2

Senile Cataract

Question 3

It is the world’s leading cause of treatable blindness:

Answer 3

Senil Cataract

Question 4

Gradual progressive visual deterioration, disturbance in night and near vision, decreased visual acuity, glare and monocular diplopia :

Answer 4

Presentation

Question 5

The most common complaint of patients with senile cataract:

Answer 5

Decreased visual acuity

Question 6

Decrease in contrast sensitivity in brightly lit environments or disabling glare during the day or oncoming headlights at night:

Answer 6

Glare

Question 7

The progression of cataract frequently increases the anteroposterior (AP) axis and therefore the diopteric power of the lens resulting in:

Answer 7

Myopic shift (increased myopia)

Question 8

The monocular diplopia is not correctable with:

Answer 8

Spectacles, prisms or contact lenses

Question 9

When the patient complains of glare, visual acuity should be tested in a:

Answer 9

Brightly lit room

Question 10

Detects a Marcus Gunn pupil or a relative afferent pupillary defect (RAPD) indicative of optic nerve lesions or diffuse macular involvement:

Answer 10

Swinging flashlight test

Question 11

Are requested when a significant posterior pole pathology is suspected and an adequate view of the back of the eye is obscured by a dense cataract:

Answer 11

Ultrasonography, CT or MRI

Question 12

Clinical staging of senile cataract is based largely on:

Answer 12

the visual acuity of the patient

Question 13

Clinical staging of senile cataract:

Answer 13

Hypermature, mature, immature and incipient

Question 14

Patient reports visual complaints but can still read at 20/20 despite lens opacity confirmed via slit lamp examination:

Answer 14

Incipient Cataract (Dysfunctional Lens Synd.)

Question 15

Patient can distinguish letters at lines better than 20/200:

Answer 15

Immature Cataract

Question 16

Patient cannot read better than 20/200 on the visual acuity chart:

Answer 16

Mature Cataract

Question 17

Patient generally sees worse than count fingers (CF) or hand motion (HM) owing to a dense white, deeply dark opaque brunescent, or Morgagnian cataract:

Answer 17

Hypermature Cataract

Question 18

is the definitive treatment for senile cataract:

Answer 18

Lens extraction and Intraocular lens implantation

Question 19

Involves extraction of the entire lens, including the posterior capsule and zonules:

Answer 19

Intracapsular Cataract Extraction

Question 20

Involves the removal of the lens nucleus through an opening in the anterior capsule and a relatively large limbal incision, with retention of the integrity of the posterior capsule

Answer 20

Extracapsular Cataract Extraction

Question 21

Also involves extraction of the lens nucleus through an opening in the anterior capsule; an ultrasonically driven needle is used to fragment the nucleus of the cataract; the lens substrate is then aspirated through a needle port via a small limbal or scleral incision:

Answer 21

Phacoemulsification
