Introduction
Nailfold video capillaroscopy (NVC) is a non-invasive diagnostic tool used to examine the microcirculation of the nailfold capillaries. It is widely used in the diagnosis of various autoimmune diseases, including dermatomyositis. In this article, we will discuss the working principle, advantages, who needs it, and the application industries of NVC in dermatomyositis.
Working Principle
NVC uses a digital camera connected to a microscope to capture images of the nailfold capillaries. The patient’s finger is placed under the microscope, and the images are magnified up to 200 times. The images are then analyzed to determine the morphology of the capillaries, including their density, shape, and distribution. In dermatomyositis, NVC can identify characteristic capillary abnormalities, such as enlarged and tortuous capillaries, loss of capillary density, and avascular areas.

Advantages
A. Non-invasive: NVC is a non-invasive procedure that does not require any incisions or injections.
B. Safe: NVC is a safe procedure that does not expose the patient to any radiation.
C. Quick: NVC is a quick procedure that can be completed within a few minutes.
D. Cost-effective: NVC is a cost-effective diagnostic tool that can help reduce the need for more invasive procedures.
Who Needs NVC?
Patients with suspected dermatomyositis may need NVC as part of their diagnostic workup. NVC can help identify characteristic capillary abnormalities that are often seen in dermatomyositis patients. Additionally, NVC can be used to monitor disease activity and response to treatment.
Application Industries
A. Rheumatology: NVC is widely used in rheumatology to diagnose and monitor various autoimmune diseases, including dermatomyositis.
B. Dermatology: NVC can be used in dermatology to diagnose and monitor skin diseases that affect the microcirculation, such as scleroderma.
C. Vascular surgery: NVC can be used in vascular surgery to assess the microcirculation of the fingers and toes before and after surgery.
D. Sports medicine: NVC can be used in sports medicine to assess the microcirculation of the fingers and toes in athletes, which can be affected by repetitive trauma.
E. Occupational medicine: NVC can be used in occupational medicine to assess the microcirculation of the fingers and toes in workers who are exposed to vibration or cold temperatures.
