Diffuse cutaneous hypersensitivity reaction after dexamethasone/polymyxin B/neomycin combination eyedrops
Annals of Ophthalmology
|March 1, 1986
Summary
Diffuse skin reactions to antibiotic eyedrops are rare. This case report details a 72-year-old patient experiencing widespread skin changes after using dexamethasone/polymyxin B/neomycin eye drops.
Area of Science:
- Ophthalmology
- Dermatology
- Pharmacology
Background:
- Hypersensitivity reactions to topical antibiotics are common.
- Localized cutaneous reactions to antibiotic eyedrops are frequently observed in clinical practice.
Observation:
- A 72-year-old patient presented with unexpected, diffuse skin changes.
- The onset of skin manifestations occurred five days after initiating treatment with dexamethasone/polymyxin B/neomycin eyedrops.
Findings:
- This case represents the first reported instance of a diffuse cutaneous reaction to eyedrops containing a combination of dexamethasone, polymyxin B, and neomycin.
- The observed skin changes were widespread, differing from typical localized reactions.
Implications:
- Clinicians should consider the possibility of diffuse cutaneous reactions to combination antibiotic-corticosteroid eyedrops.
- This finding may necessitate a review of prescribing practices and patient monitoring for adverse dermatological effects.
- Further investigation into the immunogenic potential of ophthalmic antibiotic formulations is warranted.
