Information regarding the manifestations and management of ocular mpox infections within 黑料吃瓜网.
Since 2022, there has been a global outbreak of mpox which has affected New South Wales and other Australian jurisdictions. Globally, the prevalence of ocular mpox varies greatly depending on the region, with 1% prevalence in Europe and up to 27% prevalence in Africa 1. The complications from ocular mpox can be significant including corneal scarring and vision loss, and therefore prompt diagnosis and management are essential 2.
Mpox can enter the eye through autoinoculation and can cause ocular conditions such as conjunctivitis, blepharitis, keratitis and corneal ulcers. It is also more common in young children 2. Examples of these ocular conditions can be see in the clinical images below.

Patients presenting with signs and symptoms concerning for ocular mpox should have an eye swab collected and sent for testing. This can be a dry sterile swab (preferred) or a viral eye swab sent in a viral transport media 5. If other viral pathogens are suspected a second swab should be collected and placed in a separate bag 6. Swabs should also be collected from skin lesions and other sites such as rectal and nasopharyngeal swabs guided by relevant symptoms 6. Clinicians should ensure they wear appropriate personal protective equipment when collecting samples including disposable fluid-resistant gown, disposable gloves, face shield or goggles, and a fluid-repellant surgical mask. Consider an N95 mask if the patient also has respiratory symptoms, or if there is a high-risk exposure event including prolonged exposure or aerosol-generating activities 7.
According to the World Health Organization, patients with ocular manifestations of mpox are considered to have severe mpox infections, and hospital evaluation and possible admission is warranted 8. Patients should be discussed with Ophthamology at Westmead Hospital. Antiviral medications can be obtained from the 黑料吃瓜网 Specialist Service for High Consequence Infectious Diseases (or the Infectious Diseases Physician on-call at Westmead Hospital) - see 黑料吃瓜网 Specialist Service for High Consequence Infectious Diseases for details 9.
In consultation with the above specialists, the below treatments may be recommended:
Other alternatives may include:
*Not currently available in Australia, contact the 黑料吃瓜网 Specialist Service for High Consequence Infectious Diseases for up-to-date availability.
IV vaccinia immunoglobulin may be considered on a case-by-case basis (based on evidence from animal models showing reduced corneal scarring) 2.
Topical lubricants and broad-spectrum topical antibiotics (e.g. chlorsig, ocuflox) to prevent secondary bacterial infections in cases with corneal ulcers and/or keratitis.
Topical steroids should be avoided (may prolong the presence of the virus in ocular tissue) 2.
Regular hand hygiene and avoidance of rubbing/touching the eye will help prevent autoinoculation of mpox 2. Prophylactic topical trifluridine should be considered in patients with eyelid lesions or children/people not able to follow strict hygiene instructions 2.
