Introduction
•
Purpose
– To examine the characteristics and visual outcome in 207 patients with
retinal vasculitis.
– To examine factors predictive of visual outcome in this population.

Methods
•
Study Design
– Retrospective medical record review.
•
Study Population
– 207 cases of retinal vasculitis identified from 1390 patients attending
the uveitis clinic at Oregon Health & Science University between 1985
and 2010.

Methods
•
Data Analysis
– Frequencies of variables tabulated for descriptive analysis.
– Kaplan-Meier method applied to compute proportions of visual acuity
improvement as a function of follow-up time.
– Cox proportional hazards model with shared-frailty controls for withinindividual correlation.

Results
• 75 eyes (36.9%) had visual acuity of 20/25 or better at baseline.
• 33.6% of eyes with visual acuity worse than 20/25 at baseline experienced
visual acuity improvement of at least 2 lines on the Snellen chart during
follow-up, and some continued to improve more than 9 years after the
initial evaluation.
• Positive prognostic factors: nonwhite race, worse visual acuity at baseline,
ocular infection.
• Negative prognostic factor: primary retinal vasculitis.

Comment
•
This is the first case series to examine visual outcome of retinal vasculitis
in a population from North America.
•
Limitations
– Heterogeneity of retinal vasculitis.
– Accuracy and consistency of data less than from a prospective study.
– Patients had varying lengths of follow-up.
– Data largely represent a northwestern US population.
– Cases may be more severe than seen in primary clinics.

Work Under Way
– Identifying subsets of retinal vasculitis and the prognosis of
each subset.
– Prognostic importance of associated physical and angiographic
findings.
