With reference to the study of the robotic system for ophthalmology microsurgery, a robotic system was presented with the key mechanism design and control subsystem scheme considering the procedures and features of retinal vascular bypass surgery. After discussion of the clinical application, the human-machine cooperated surgical process of the robotic system for retinal vascular bypass surgery was described, and the design of the surgical layout environment was proposed. The intraocular motion planning method was also described and corresponding experiments using a table tennis ball model and an in vitro porcine eye model were performed. Finally, the feasibility analysis and robotic system error analysis were also summarized and future works discussed for further research.

Diffuse dermal angiomatosis (DDA) is a benign, acquired, reactive vascular proliferation. DDA is clinically characterized by painful purpuric plaque with central ulceration. The histopathologic hallmark is diffuse proliferation of endothelial cells that are arranged interstitially between collagen bundles of the reticular dermis. DDA has been reported in association with peripheral atherosclerotic disease, arteriovenous fistula and heavy smoking. We report the case of a 49-year-old Asian male with DDA who presented with a painful stellate-shaped purpuric patch on the right thigh. Histopathologic examination showed proliferation of CD34-positive spindle cells in the dermis. Our patient underwent vascular bypass surgery along with tight control of cardiovascular risk factors, which yielded successful results.
