QUESTIONS


1A 64-year-old white woman presents with complaints of pain, decreased vision, and a red eye for the past 2 days (Fig. 8-1). Her medical history reveals that she had a trabeculectomy for primary open-angle glaucoma in this same eye 6 months before. What would a Gram stain of the vitreous fluid of this patient most likely show?

QUESTIONS 2–4 A 69-year-old white man presents with mild discomfort and reports a gradual decrease in the vision of his right eye over the course of 1 week. His ocular history is remarkable for cataract extraction and posterior chamber intraocular lens (IOL) insertion in this eye 4 months previously. Because of the low-grade nature of the inflammation, topical steroids are begun, and the inflammation responded favorably. After discontinuing the steroids, the symptoms return and the patient again presents with a granulomatous anterior chamber inflammation, including a small hypopyon and a mild anterior vitritis.


2What would examination of the white plaque present at the equator of the posterior lens capsule most likely reveal?


 A)Candida albicans


 B)Propionibacterium acnes


 C)Staphylococcus epidermidis


 D)Mycobacterium tuberculosis


3Which one of the following is the most appropriate therapy for this condition?


 A)Vitrectomy and intravitreal injection of amphotericin B


 B)Observation


 C)Vitrectomy, removal of the IOL, and intravitreal injection of gentamicin


 D)Vitrectomy, posterior capsulectomy, and intravitreal injection of vancomycin


4What is the least likely microbial cause for this syndrome?


 A)P. granulosum


 B)Achromobacter


 C)Klebsiella


 D)Corynebacterium


QUESTIONS 5–7 A 32-year-old African American woman presents with floaters and blurred vision in her right eye. Slit lamp examination shows nodules on the iris (Fig. 8-2). A recent chest radiograph revealed hilar adenopathy.
