Summary

The Uveitis, the inflammation of the uvea, is a rare disease with an incidence of 52/100,000 inhabitants per year and a prevalence of 115 / 100,000 inhabitants per year.

The causes of uveitis are numerous and include infectious diseases, systemic and neurological diseases, ophthalmic entities, neoplasia, and drug-related reactions. The etiological diagnosis is important both for prognosis and therapeutics.

However, clinical evaluations to establish etiological diagnosis are not standardized. Some authors suggest a minimalist examination, common to all kinds of uveitis. On the other hand, others propose an evaluation guided by the anatomo-clinical type of uveitis.

We conducted a retrospective study to assess the contribution of complementary examinations to etiological determination. In this study, we found that most patients benefited from a wide paraclinical evaluation compared to what is usually described in the literature. Complementary examinations were mostly systematic, without any clinical or ophthalmological elements of orientation. This study highlighted the lack of contribution of some examinations.

Using these results, and the literature analysis, we designed a diagnostic algorithm adapted to the anatomo-clinical type of uveitis.

Moreover, we found that the average cost per patient was estimated at €290.51 with the algorithm compared to €560.83 without it.

We would like to carry out a new study to estimate the efficiency as well as the medico-economic impact of the use of a standardized strategy for the etiological diagnosis of uveitis, compared with a free strategy.

Hypothesis:

* The standardized strategy for the diagnostic of uveitis is at least as efficient as the free one, and costs half as much.
* The examinations prescribed, except for those from the standardized strategy, do not contribute to etiological determination.

Conditions

  • Uveitis

Interventions

OTHER

Free strategy

Free strategy followed in order to make the etiological diagnosis, which means, investigators are free to perform any examination they thought necessary.

OTHER

Standardized strategy

Etiological diagnosis made by following a standardized two-stage strategy: first-line assessment (listed examinations and then examinations directed by the clinical or para-clinical elements of orientation) and second or third-line assessment (examinations directed by the anatomo-clinical type of uveitis).
