In May 2002, Deborah Cobb, a 19-year-old from Seattle, performed 13 cartwheels in a row on Westport beach in Washington while enjoying a day with friends. After collapsing from dizziness, she noticed her vision blurred, seeing only an orange blur when looking directly at her friend's face. Her peripheral vision remained unaffected, but central vision failed, prompting concern. Initially, Cobb initially dismissed the issue as mere temporary disorientation, but the symptoms persisted into the following morning, leading her stepfather to take her to the emergency room.
An ophthalmologist diagnosed Cobb with ruptured blood vessels in her macula, the retina's central part responsible for detailed vision. The small amount of blood blocked her central vision, rendering her legally blind. Doctors informed her that healing could take three months, during which she could not drive, read, or watch television. This diagnosis disrupted her daily life, forcing reliance on others for tasks like preparing meals or sending texts. Friends provided support, but the experience challenged her independence.
After three months, Cobb’s central vision gradually returned as the blood reabsorbed. However, she experienced milder vision loss episodes later, including one during a car singalong and another while weeding. Medical professionals noted that repeated head inversion, like during cartwheels, could increase retinal vein pressure, potentially causing macular hemorrhage in susceptible individuals. Cobb’s condition may have a genetic link, as a distant family member reported similar issues.
Long-term effects persist, with Cobb, now 42, experiencing flashes of light and dark floaters due to retinal jelly detachment. Surgery remains an option, but it risks cataracts, leading her to avoid it. During pregnancy, doctors advised a scheduled C-section to prevent strain-induced vision loss, ensuring she could see her newborn son.
Cobb, now an integrative health practitioner, has not attempted cartwheels since the incident. The experience reshaped her perspective, highlighting the importance of appreciating daily abilities. Her case, though rare, underscores the potential risks of vigorous physical activities for some individuals. Medical monitoring continues to manage her condition, with the possibility of future complications remaining a concern.
