Primary Outcome Measures

Name	Time	Method
Change from baseline in visual assessment scores at 3 months	Baseline and 3 months	The visual assessment evaluates seven clinical signs: erythema, edema, wheal vesiculation, ulceration, hemorrhage, purpura, and crusting. Each sign is assigned a score of 0 to 3, where a score of 0 is associated with no expression of the clinical sign and a better outcome, and a score of 3 is associated with severe expression of the clinical sign and a worse outcome.
