ABSTRACT
This case report describes a patient with a chronic urinary tract infection whose long-term treatment for right eye redness, discharge, pain, and decreased vision ultimately led to hospitalization and Pseudomonas aeruginosa resistant to multiple antibiotics.

Ocular manifestations of Noonan syndrome (NS) in a set of healthy 20-year-old African-American fraternal twins are reported with emphasis on a rare finding of keratoconus with acute corneal hydrops in one twin. Both the twins had learning disabilities and attended a special needs school. Evaluation included visual acuity assessment, tonometry and external eye, slit lamp and dilated fundus examinations, topography with Pentacam and external photographs. The first case was more remarkable as keratoconus with acute corneal hydrops was observed. The patient presented with severe cloudy vision that had worsened over a span of 1 month. It improved significantly on follow-up. The second case included a unique constellation of ocular pathology that highlights the diversity of NS manifestations even amongst twins. Conservative treatment of keratoconus with acute corneal hydrops in a NS patient helped largely resolve the patient's condition. We report the diverse spectrum of ocular manifestations associated with this rare congenital disorder.

PURPOSE: Pseudodendritic keratitis in a contact lens wearer is generally associated with acanthamoeba keratitis. We report a case of isolated pseudodendritic fungal epithelial keratitis that occurred in an extended wear contact lens user. METHODS: A 48-year-old woman was evaluated in our clinic for a 36-hour history of left eye pain. She wore extended wear soft contact lenses and frequently rinsed her eyes with tap water. Her left cornea had a paracentral 3-mm area of epithelium with raised ridges in a pseudodendritic pattern. The underlying corneal stroma was normal. A therapeutic and diagnostic corneal scraping of the lesion was performed and sent for Gomori methenamine silver (GMS) staining. The clinical concern was for epithelial acanthamoeba keratitis. RESULTS: The GMS staining revealed septate fungal hyphae within sheets of corneal epithelium. The patient was started on frequent alternating natamycin (5%) and amphotericin B (0.15%) antifungal eyedrops and exhibited a rapid clinical response. Her keratitis completely resolved, and her vision returned to her baseline of 20/25. Corneal fungal cultures showed no growth. CONCLUSIONS: Our case is an extremely unusual presentation of fungal keratitis, which rarely presents as a pseudodendritic epithelial keratitis. There are two previous similar case reports initially misdiagnosed as acanthamoeba keratitis. Clinicians should be aware that isolated fungal epithelial keratitis can present as a distinct entity and should be considered in the differential diagnosis of pseudodendritic keratitis. The GMS staining is an excellent diagnostic test in a patient presenting with pseudodendritic keratitis because it allows rapid diagnosis of acanthamoeba and fungal infections.
