The eye is drawing the most venture capital funding, according to the Wall Street Journal.
The Journal's Brian Gormley sifted through data on what sorts of startups were getting VC money, and then went through them body part by body part to see which ones were getting the most funding.
Eye-related startups, Gormley reports, received $848.9 million last year and have received $442.7 million so far this year. "Investment has surged because of rising demand for better treatments and technological advances that are making improvements possible," Gormley says, noting that some 3 million people in the US over the age of 40 have impaired vision or are blind.
There's also rising interest in the ears, Gormley says, adding that hearing loss and related issues affect a third of people in the US between the ages of 65 and 74. Hearing-related startups garnered $76.2 million last year, and, in the first half of this year, they have raised $114.4 million.
Interest in cardiovascular and orthopedic startups remains high, Gormley notes, though investors are concerned about regulatory delays.
