Ipsilateral deafness and herpes zoster ophthalmicus

Area of Science:

• Ophthalmology
• Neurology
• Audiology

Background:

• Herpes zoster ophthalmicus (HZO) is a viral infection affecting the ophthalmic nerve.
• Complications of HZO can extend beyond the eye.
• The association between HZO and ipsilateral deafness is not well-documented.

Observation:

• Three patients presented with sudden, unilateral hearing loss concurrent with HZO.
• Literature review revealed no previously reported identical cases.
• This suggests a potentially underrecognized complication of HZO.

Findings:

• Ipsilateral deafness occurred in all three observed cases of HZO.
• The study highlights a possible link between HZO and auditory dysfunction.
• No satisfactory treatment currently exists for HZO-associated sudden deafness.

Implications:

• Prompt audiological evaluation is crucial for patients with HZO experiencing auditory symptoms.
• Early detection of hearing loss through audiograms can aid in management, despite limited treatment options.
• Further research is warranted to understand the pathophysiology and incidence of HZO-induced deafness.
