Can I lose an eye from a dental procedure?
The gist: A woman went in for a routine procedure, wasn't given safety glasses to wear, and the dentist dropped the needle used to inject a local anesthetic into her eye by accident. The needle wasn't the main issue but because the mouth is a cesspool of bacteria, an eye infection resulted. After various surgeries/antibiotics, they ended up having to remove her eye. So even if those glasses leave weird marks on your face, you should still wear them.
Did you hear about that mysterious eye condition affecting astronauts?
VIIP = visual impairment intracranial pressure syndrome.
This is the coined term for the mysterious condition that affects the eyesight of 80% of astronauts after a long duration in space. Although not completely understood, the condition is similar to idiopathic intracranial hypertension (IIH). Astronauts present with choroidal folds and occasionally disc edema though the reason why is unclear. The theory is there is increased intracranial pressure but confirming that theory is difficult because doing a lumbar puncture in space is, quite frankly, rocket science and not exactly ideal. Unlike the symptoms of headache, nausea and dizziness that come with IIH, the only symptoms astronauts reported were blurry vision. In some cases, the vision dropped to 20/100 which makes for an exciting space walk.
