Scam-y stem cells?

A federal judge sided with the FDA to crack down on unapproved stem cell clinics.

Give me the background on this ruling.

In 2018, the FDA took legal action against a Florida stem cell clinic when three women went blind after receiving intravitreal injections of stem cells from the clinic to treat their AMD. Before the injection, their vision ranged from 20/30 to 20/200, but afterwards they had 20/200 to LP vision. The injection contained stem cells that were obtained from fat removed from their abdomen through liposuction.

Why is the FDA involved?

Because the clinic is essentially making a drug to give to patients and that sort of thing needs to be regulated by the FDA. The clinic however says that because they are using the patients own stem cells, it falls within an exception from FDA regulations for "minimally manipulated" tissues or substance. The federal judge reviewing the case didn't buy it and sided with the FDA. (via)

Goldman Sachs wants to talk eye health

Are there glasses that can prevent myopia progression?

There is a promising option on the horizon. A research team has collaborated with Hoya on a new spectacle lens called the Defocus Incorporated Multiple Segments (DIMS) lens.

What is the DIMS lens?

The lens has a central optical zone for correcting refractive error, but the key is the multiple little micro-lenses that create constant myopic defocus surrounding the central zone extending to the mid-periphery of the lens. Here is a picture. Think of an ad on a bus window, where a meshwork of dots makes up the picture so that you can still see through the window.

Why do we want peripheral myopic defocus?

Because studies have shown that in order to control myopia progression we need to induce myopic defocus in the periphery.

Tell me about the clinical study.

The trial involved 160 Chinese children (ages 8-13), 79 of which were assigned the DIMS lens. The 2-year study results showed that the children wearing DIMS lenses had a 52% reduced rate of myopia progression compared with those who wore single-vision lenses. It’s also important to note that 21.5% of kids who wore DIMS lenses had no myopia progression over 2 years, compared with 7.4% of kids who wore single-vision lenses.


The ophthalmology world lost a great one.

Legendary ophthalmologist Patricia Bath died last Thursday. She took a "special interest in combating preventable blindness in underserved populations and became the first black female doctor to patent a laser device for treating cataracts." (via)

Someone should tell this woman about daily contacts.

An NFL network reporter gets a corneal ulcer and makes a PSA for better contact lens habits.
