| 1. | A care aide at a long-term care facility has informed a resident physician that an 80-year-old woman’s eyes appear to be inflamed and that her eyelids are caked with sticky secretions. The woman has been subsequently diagnosed with posterior blepharitis. Which of the following treatments is the physician likely to initiate? | |
| A) | Surgical repair of the woman’s blocked meibomian glands | |
| B) | Warm compresses to be applied regularly to her eyes in addition to oral antibiotics | |
| C) | Regularly scheduled cleansing of the woman’s eyes with normal saline | |
| D) | Intravenous steroids coupled with topical antibiotic ointment | |
| Ans: | B | |
| Feedback: | ||
| Treatment of posterior blepharitis is determined by associated conjunctival and corneal changes. Initial therapies can include warm compressing of the lids and use of flaxseed or fish oil tablets to provide omega-3 fatty acid benefits to meibomian oil secretions. Long-term, low-dose systemic antibiotic therapy guided by results of bacterial cultures along with short-term topical steroids may also be needed. | ||
| 2. | The father of a third grade girl has brought his daughter to a walk-in clinic because he believes the girl has pink eye, which has been going around the students in her class. The nurse at the clinic concurs with the father’s suspicion of conjunctivitis. Which follow-up explanation by the nurse is most accurate? | |
| A) | “The insides of her eyelids have become infected. This often produces severe discomfort.” | |
| B) | “The surfaces of her eyes have bacteria or a virus established, and it’s important to maintain good hand hygiene until it goes away.” | |
| C) | “An antibiotic ointment will likely resolve her infection, but pain control will be necessary in the mean time.” | |
| D) | “It’s important to aggressively treat this in children, since damage to her sight can result if it’s not treated.” | |
| Ans: | B | |
| Feedback: | ||
| Conjunctivitis often spontaneously resolves. The pain associated with conjunctivitis usually produces only mild discomfort compared with severe discomfort associated with corneal lesions or deep and severe pain associated with acute glaucoma. Conjunctivitis may spread to other family members. The corneal surface is not primarily involved, and pain that is severe suggests corneal involvement rather than conjunctivitis. Sight damage is not likely to result. | ||
| 3. | A 32-year-old man is complaining of burning, itching, photophobia, and severe pain in his right eye after swimming in the ocean. To determine that the eye condition was a corneal rather than a conjunctival disease, which of the following would be the distinguishing symptom? | |
| A) | Burning | |
| B) | Itching | |
| C) | Photophobia | |
| D) | Severe pain | |
| Ans: | D | |
| Feedback: | ||
| While burning, itching, and photophobia are all important symptoms of conjunctivitis, severe pain suggests corneal rather than conjunctival disease. | ||
| 4. | A 30-year-old woman has sought care because of her recurrent photophobia, tearing, and eye irritation. During assessment, her care provider asks about any history of cold sores or genital herpes. What is the rationale for the care provider’s line of questioning? | |
| A) | Herpes simplex virus (HSV) conjunctivitis indicated a need for antiviral rather than antibacterial treatment. | |
| B) | HSV infection of the cornea is a common cause of corneal ulceration and blindness. | |
| C) | Chronic viral infection of the eyes can result in HSV autoinoculation of the mouth and labia. | |
| D) | A history of HSV with eye irritation is suggestive of glaucoma. | |
| Ans: | B | |
| Feedback: | ||
| Herpes simplex virus (HSV) keratitis (not conjunctivitis) with stromal scarring is the most common cause of corneal ulceration and blindness in the Western world. Autoinoculation from the eyes to other sites is not common, and glaucoma is not noted to be a consequence or symptom of HSV infection. | ||
