Assessment of retinal arteriolar tortuosity in patients with COL4A1 or COL4A2 mutations.

Purpose: Qualitative and quantitative analyzes of retinal arteriolar tortuosity (RAT) in patients with COL4A1 and COL4A2 mutations to identify a tortuosity index (TI) threshold for detecting increased RAT.

Methods: Fifty-two eyes of 28 patients were included. Group 1 included eyes with a normal arteriolar pattern (n=19, 37%), group 2 included eyes with moderately increased arteriolar tortuosity (n=13, 25%), and group 3 included eyes with typical abnormal arteriolar tortuosity (n=20, 38%).

Efficacious switching from subcutaneous to intravenous tocilizumab in patients with non-infectious non-anterior uveitis.

Purpose: The efficacy of tocilizumab in refractory chronic noninfectious uveitis has been previously reported, but no data comparing intravenous and subcutaneous tocilizumab in uveitis are available.

Results: We report a case series of patients with chronic noninfectious uveitis with incomplete efficacy of subcutaneous tocilizumab, improved after switching to intravenous routes. Improvement of visual acuity was observed with intravenous tocilizumab for all patients.
