Intermediate uveitis, posterior uveitis, and panuveitis in the Mid-Atlantic USA.
BACKGROUND
The purpose of this study was to identify the causes, clinical features, and outcomes of intermediate uveitis, posterior uveitis, and panuveitis in patients managed in a mid-Atlantic tertiary care center.


METHODS
This was a retrospective observational study of intermediate uveitis, posterior uveitis, and panuveitis patients seen at the University of Virginia from 1984 to 2014.


RESULTS
One hundred and fifty-nine intermediate uveitis, posterior uveitis, and panuveitis patients (237 eyes) were identified. The patient population was 54.72% female; 67.30% of patients were Caucasian, and 22.01% were African-American. Mean age at diagnosis was 45.5 years. Mean duration of follow-up was 3.95 years. Mean number of visits to the clinic was 10.35. Of 491 uveitis patients, 26 (5.30%) had intermediate uveitis, 62 (12.60%) had posterior uveitis, and 71 (14.50%) had panuveitis. The leading diagnoses in the intermediate uveitis group were pars planitis (73.08%) and sarcoidosis (11.54%); toxoplasma uveitis (17.74%), multifocal choroiditis (14.52%), undifferentiated posterior uveitis (14.52%), and birdshot chorioretinitis (11.29%) in the posterior uveitis group; and undifferentiated panuveitis (29.58%), post-surgical panuveitis (18.31%), sarcoidosis (12.68%), acute retinal necrosis (12.68%), and toxoplasma uveitis (4.23%) in the panuveitis group. The most common treatment modalities included local steroids (57.23%) and systemic steroids (42.14%). Ocular hypertension was found in 38 patients (23.90%). Glaucoma surgery was performed in 18.24% of patients and cataract surgery in 21.38%. Mean best-corrected visual acuity was 0.66 logMAR at baseline across all anatomical locations and 0.57 logMAR at final follow-up. Best-corrected visual acuity improved or remained stable during follow-up in all groups.


CONCLUSIONS
The most common diagnoses in our series by anatomical location were pars planitis (intermediate uveitis), toxoplasmosis (posterior uveitis), and undifferentiated uveitis (panuveitis). Panuveitis had significantly worse visual outcomes and higher rates of complications than did intermediate or posterior uveitis, a finding that confirms earlier reports. In this series, unilateral disease, regardless of anatomical location, was associated with poorer visual outcome, in contrast with the findings of other reports.
