Clinical features, diagnosis, treatment, and course of ocular sarcoidosis with or without uveitis: A retrospective, comparative study

OBJECTIVE

To evaluate and compare characteristics, diagnosis, treatment, visual prognosis, and course between ocular sarcoidosis with or without uveitis in a population in Southern France.

METHODS

We retrospectively analyzed data from patients with ocular sarcoidosis in a tertiary eye care center in Nice from January 2003 to December 2021. The inclusion criterion was biopsy-proven ocular sarcoidosis according to IWOS criteria as the first clinical manifestation of sarcoidosis.

RESULTS

A total of 25 patients were included. Twenty patients had uveitis (70% panuveitis, 20% intermediate uveitis, and 10% anterior uveitis) and five patients had non-uveitic ocular sarcoidosis (one patient with dacryoadenitis, one patient with orbital granuloma, two patients with palpebral granuloma, and one patient with episcleritis). Only the cases with uveitis had bilateral involvement (85% of cases). There was no significant difference in ethnicity, biopsy diagnosis, systemic manifestations, or treatment between the two groups. Final visual outcomes remained good for both groups, with 96% of patients with BCVA>20/50, with no significant difference. Patients with non-uveitic sarcoidosis experienced less recurrence on treatment (P=0.042) and more remission (P=0.038) than patients with uveitis. Eighty percent of patients with uveitis had at least three suggestive clinical intraocular signs meeting IWOS criteria.

CONCLUSION

In this population in Southern France, uveitis was the most common presentation of ocular sarcoidosis. The type of ocular sarcoidosis does not appear to be correlated with the type of systemic manifestations, use of systemic therapy, or visual prognosis, but patients with non-uveitic ocular sarcoidosis appear to have a better course with fewer recurrences on treatment and more remission than patients with uveitic ocular sarcoidosis.
