What this trial studies

This observational study will enroll people with psoriasis at dermatology clinics and perform nailfold capillaroscopy to identify microvascular changes. Researchers will compare capillaroscopic findings with disease severity and examine differences across clinical psoriasis types and Fitzpatrick skin phototypes. The study will collect clinical assessments and capillaroscopy results to explore possible associations. No intervention will be given beyond the imaging procedure, and participants will be observed in an outpatient setting.
