Activity B MATCHING

4.

Match the papillary abnormality with its description.

Answer Description Pupillary Abnormality

Unequal pupils A. Tonic pupil

Does not cause anisocoria as long as the sympathetic and parasympathetic innervation to both irises is normal

B. Horner syndrome

Reaction to light is severely reduced and slowed, or even absent

C. Oculomotor nerve (CN III) paralysis Pupils that accommodate but do not

react to light

D. Anisocoria

The dilated pupil is fi xed to light and near effort. Ptosis of the upper eyelid and lateral deviation of the eye are almost always present

E. Equal pupils and one blind eye

The affected pupil, though small, reacts briskly to light and near effort.

Ptosis of the eyelid is present, perhaps with loss of sweating on the forehead

F. Small, irregular pupils (Argyll Robertson pupils)

5.

Match the lump or swelling in and around the eye with its description.

Answer Lump or Swelling Description

Pinguecula A. A localized ocular redness from infl ammation of the episcleral vessels Hordeolum B. A swelling between the lower eyelid

and nose

Xanthelasma C. A subacute, nontender, and usually painless nodule involving a meibo- mian gland

Episcleritis D. A painful, tender red infection in a gland at the margin of the eyelid Chalazion E. Yellowish triangular nodule in the

bulbar conjunctiva on either side of the iris
