Demographic Features, Diagnoses and Real-World Clinical Management of Uveitis in Japan.

PURPOSE: This study aimed to investigate demographic features, diagnoses of uveitis (intraocular inflammation), and real-world clinical practice in the use of local and systemic therapies for patients with uveitis in Tokyo, Japan.

METHODS

Clinical records of 1,174 consecutive new patients (480 males, 694 females) referred to the Kyorin Eye Center, Kyorin University Hospital between January 2011 and December 2018 were retrospectively reviewed.

RESULTS

Mean age at presentation was 52.6 years (range 4-94 years). By anatomic location, 439 patients (37.4%) had anterior uveitis, 18 (1.5%) had intermediate uveitis, 214 (18.2%) had posterior uveitis and 503 (42.8%) had panuveitis. The 3 most common diagnoses were sarcoidosis (9.1%), Vogt-Koyanagi-Harada (VKH) disease (8.3%), and acute anterior uveitis (5.7%). Compared to our previous study, rates of herpetic anterior uveitis and cytomegalovirus (CMV) retinitis increased while tuberculosis-related uveitis decreased. Unclassified uveitis remained the most common diagnosis (44.9%). Systemic corticosteroids and/or immunomodulatory agents were used in only 18.3% of patients. Immunomodulatory drugs including biologic agents were utilized in 4.9% of patients.

CONCLUSIONS

The most common uveitis anatomic type was panuveitis due mainly to high rates of sarcoidosis and VKH disease. Diagnoses of herpetic anterior uveitis and CMV retinitis increased, while tuberculosis-related uveitis decreased. Less than one-fifth of uveitis patients required systemic treatment.
