Discharge Summary:

Patient: 62-year-old female

Admission Date: [Date]

Discharge Date: [Date]

Diagnosis: Corneal Ulcer in the Left Eye

Hospital Course Summary:

The patient was admitted to the hospital for evaluation of a corneal ulcer in her left eye. The patient had a history of allogeneic hematopoietic stem cell transplant for treatment of myelodysplasia syndrome. The patient's corneal ulcer was complicated by severe keratoconjunctivitis sicca and cGVHD affecting the liver, skin, esophagus, mouth, and eyes. The patient's medical status was further complicated by systemic steroid dependence and steroid-induced diabetes mellitus.

Treatment:

The patient was empirically treated with topical 0.5% moxifloxacin (Vigamox, Alcon) that was applied 6 times a day. After 4 days, the treatment failed to improve the condition, and the patient was referred to Massachusetts Eye and Ear Infirmary. Upon presentation, the central cornea was opaque and neovascularized, and there was an epithelial defect with an underlying infiltrate.

Outcome:

Four days after culture and modification of the antibiotic delivery regimen, the corneal ulcer resolved, with re-epithelialization of the cornea surface and resolution of the infiltrate. A strain of E. coli cultured from the lesion was resistant to fluoroquinolones, trimethoprim/sulfamethoxazole, ampicillin, and ampicillin-sulbactam.

Discharge Plan:

The patient was discharged with instructions to follow up with their ophthalmologist and primary care physician. The patient was advised to continue to monitor their symptoms and to follow their treatment plan. They were educated on the importance of maintaining good hygiene practices and avoiding the use of contact lenses until further notice. The patient was advised on the potential side effects of the antibiotics used during treatment and the importance of completing the full course of antibiotics. 

Follow-up:

The patient was referred to infectious disease specialists for further management of antibiotic resistance. The patient was advised to follow up with their ophthalmologist for routine eye examinations and to monitor their diabetes mellitus to prevent further complications. The patient was also advised to follow up with their primary care physician for routine health maintenance visits.
