Abstract
PURPOSE: To analyze baseline clinical and imaging risk factors associated with poor outcome in patients with tubercular serpiginous-like choroiditis (TB SLC). DESIGN: Retrospective clinical study. METHODS: Charts and fundus photographs of consecutive patients with active TB SLC seen at a single tertiary referral center with 6 months follow-up after initiation of treatment were reviewed. Logistic mixed models were performed to determine the clinical and imaging factors associated with the response to therapy, including the opacity of choroiditis graded according to a 3-point scale. RESULTS: This study included 203 eyes of 183 patients with active TB SLC. Poor initial best-corrected visual acuity (BCVA) and foveal and optic disc involvement were associated with poor response to therapy at 6 months (odds ratio [OR] 4.489, 95% confidence interval [CI]: 1.92-10.47; P = .001; OR 2.892, 95% CI: 1.23-6.81; P = .015; OR 11.633, 95% CI: 3.17-42.71; P < .001, respectively). The high opacity grades (2 and 3) were also associated with poor outcomes OR 9.541; 95% CI: 2.94-30.91; P = .001). Poor baseline BCVA and high grade of opacity of the lesions were the composite risk factors for paradoxical worsening of TB SLC (OR 7.555, 95% CI: 1.78-32.02; P = 0.006; OR 7.434, 95% CI: 1.34-41.18; P =0.021, respectively). CONCLUSIONS: TB SLC with higher grades of lesion opacity at baseline may be associated with greater risk of poor therapeutic response and paradoxical worsening. Grading of baseline lesion opacity may be used in future prospective studies to predict the biological behavior of the lesions and may serve as a guide to therapeutic interventions.
