The awesomeness of ocular anatomy and physiology: the scleral membrane and the oculocephalic reflex as defenses against insult
Today brings one of those dismal events that afflict us all from time-to-time: a stupid accident that makes you deeply thankful for that combined achievement of evolution – a tough scleral membrane and the oculocephalic reflex. Moving furniture outside, I manage to stab myself in the dorsolateral aspect of my right eye while bending down to… Read More
