Mumps Keratoconjunctivitis In A Young Adult: A Case Report.

Mumps "mumps virus" is a mainly childhood viral disease, but which can affect young adults in 15% of cases.

This disease is most often benign but it is very contagious.

Thanks to vaccination, it is nevertheless increasingly rare.

Mumps causes inflammation of the glands. Most of the time, the disease is localized only at the parotid level.

The risk is represented by the other locations: testicle, pancreas, myocardium, meninge, brain.

the purpose of this work is to report through this case, the ocular localization of mumps in a young adult, which is exceptional.

We report the case of a 28-year-old patient, with no particular pathological history (vaccinated according to the national immunization program), admitted to the emergency room for the occurrence of a bilateral painful red eye 48 hours after the appearance of a painful bilateral parotitis, all evolving in a context of fever, headache and myalgia.

The ophthalmological examination finds:

A visual acuity of 8/10 P2 in both eyes.

Diffuse conjunctival inflammation with clear secretions.

Follicular conjunctivitis and paralimbic superficial punctate keratitis, especially lower.

General examination finds:

A temperature of 37.8. A bilateral painful swelling, between the earlobe and the jaw in favor of parotitis.

Serology detected the presence of mumps antibodies: IgM and IgG are positive.

 The patient was put on:  Twice-daily eye wash with saline solution, antiseptic eye drops, healing ointment with vitamin A and artificial tears without preservatives.

A systemicl treatment combining: Paracetamol, vitamin C with mouth care.

The evolution was spectacular.

Ocular involvement in mumps manifests as follicular or follicular papillary conjunctivitis which usually appears at the same time as the other usual signs of mumps infection and may be accompanied by chemosis and subcutaneous hemorrhage. conjunctival. Severe forms can also associate conjunctival involvement with episcleritis, scleritis, anterior uveitis and dacryoadenitis. Keratitis is rare.

The diagnosis is most of the time only clinical, the attack of two salivary glands immediately or successively signing the diagnosis of mumps.

Serology can also, in case of doubt, contribute to the diagnosis (search for IgM and rise in IgG using an ELISA test).

The ocular localization of mumps in adults is exceptional.

The best treatment and vaccine prevention. The vaccine is part of the measles-mumps-rubella (MMR) triple vaccine. This compulsory vaccine is carried out at 12 months with a booster between 16 and 18 months.

It can even be carried out from 6 or 9 months in the event of high risk or if the infant is in the community before 12 months. It confers 95% immunity and is well tolerated.
