Purpose:
To describe corneal ring infiltrates caused by Serratia marcescens in a patient with human immunodeficiency virus (HIV-1) who wore contact lenses.
Methods:
A case study of a patient with keratitis due to an infection caused by S. marcescens and exhibiting corneal ring infiltrates was reviewed for history, clinical manifestation, microscopic study, and management.
Results:
A 29-year-old man who had a history of contact lens wear and HIV-1 infection was admitted to hospital because of blurred vision, redness, and corneal infiltrates in the shape of a ring in the left eye. The visual acuity (VA) in both eyes was hand movement (uncorrected). Corneal scrapings were performed. The culture results of the corneal specimens revealed S. marcescens. The culture results of the contact lens disclosed the same organism. The corneal ulcer responded well to treatment with topical gentamycin sulfate 14 mg/ml. The final VA remained hand movement.
Conclusions:
S. marcescens can cause ring infiltrates in a HIV-1 patient who wears contact lenses. The treatment result for S. marcescens keratitis in a HIV-1 patient who wore contact lenses was favorable after intensive use of fortified topical antibiotics.
Insights
Serratia marcescens caused corneal ring infiltrates in a contact lens wearer with human immunodeficiency virus (HIV-1). Intensive topical antibiotic treatment yielded favorable outcomes for this severe keratitis case.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Microbiology
Background:
- Contact lens wear is a significant risk factor for microbial keratitis.
- Human immunodeficiency virus (HIV-1) infection can predispose individuals to opportunistic infections, including ocular infections.
Observation:
- A case study identified corneal ring infiltrates in a 29-year-old male contact lens wearer with a history of HIV-1 infection.
- The patient presented with blurred vision, redness, and ring-shaped corneal infiltrates in the left eye, with initial visual acuity of hand movement in both eyes.
Findings:
- Corneal scrapings and contact lens cultures confirmed infection by *Serratia marcescens*.
- The patient's corneal ulcer responded well to topical gentamycin sulfate treatment.
- Despite treatment, the final visual acuity remained hand movement.
Implications:
- This case highlights *Serratia marcescens* as a causative agent of corneal ring infiltrates in immunocompromised contact lens wearers.
- Prompt diagnosis and intensive topical antibiotic therapy are crucial for managing *S. marcescens* keratitis in HIV-1 patients.
- Contact lens hygiene and regular eye examinations are essential for individuals with HIV-1 to prevent severe ocular infections.
