Madarosis is a condition that results in the loss of eyelashes, and sometimes eyebrows. Madarosis is not a critical or severe condition. Madarosis can be scarring or non-scarring depending upon the etiology.
In non-scarring madarosis, follicular structures are retained and it is potentially reversible. Scarring madarosis is due to deeper inflammation and fibrosis, and it is more likely to result in permanent lash and hair loss.
Loss of the eyelashes alone is also known as milphosis.
