How does the anatomy of the eye affect the way a patient will present for an ophthalmologic emergency?
Although patients present for “eye pain” or “eye redness,” it is important to differentiate between symptoms affecting the soft tissues surrounding the eye and those affecting the orbit specifically.
4
What is the treatment for a chalazion (cyst) and a hordeolum (stye) ( Fig. 2.1 )?
Both present with swelling, pain, and erythema of the affected eyelid. Neither require antibiotic treatment. Both are best treated with frequent warm compresses and antiinflammatory pain medication.
6
Which method should be used to examine the underside of the eyelid for a foreign body?
Place a cotton-tip swab against the skin along the margin between the orbital and the superior orbital bone. Holding the patient’s upper eyelashes, the lid can then be everted by rolling the skin over the cotton-tip swab. Repeat on the lower lid.
7
How many places can a contact lens hide?
Careful examination of the cornea and sclera of a patient who has “lost” a contact lens in the eye may not reveal the missing contact. After anesthesia, evert the eyelid and sweep the upper fornix while the patient is looking down. Fluorescein stain can be used to help locate a missing lens in the eye, but staining of the lens is permanent.

What are the characteristics of different corneal injuries with examination using fluorescein stain?
See Fig. 2.2 for the different characteristics.
