Vascular dynamics during healing in periocular defects assessed with laser speckle contrast imaging.

Purpose: To evaluate the role of blood perfusion and revascularization during the healing process of periocular defects treated with following tumor excision.

Methods: Ten patients with periocular basal cell carcinomas underwent excision, followed by wound management. Blood perfusion was measured using laser speckle contrast imaging postoperatively.

Results: Immediately after excision, perfusion increased in the wound edge and the peri-wound tissue, reaching approximately 157% of reference values ( < 0.01), reflecting immediate effects of surgery. At 1 week, perfusion increased further, likely driven by inflammation and angiogenesis (193%,  < 0.001). Perfusion gradually decreased at 6-8 weeks, aligning with active tissue remodeling, and continued to normalize at 4-5 months (123%,  > 0.05). By 12 months, perfusion returned to baseline levels, reflecting wound maturation (109%,  > 0.05). In cases with directing sutures, perfusion initially decreased to 64% at the wound edge, presumably due to tension-induced hypoperfusion, but returned to baseline after 6-8 weeks.

Conclusion: This study highlights the critical role of blood perfusion in the healing of periocular defects treated with . The vascular network is preserved, enabling an immediate increase in perfusion, facilitating revascularization and wound healing. Further studies are needed to evaluate efficacy and long-term outcomes in comparison with reconstructive surgery.
