HEADACHE, ARTWORK. HEADACHE, ARTWORK Migraine. Illustration of a migraine theory explaining its onset as being triggered by a malfunction in the synchronization of sensory input which causes pain through stimulation of the trigemial nerve and inflammation from leakage in the blood vessels of the dura mater. The triptan family of drugs seems to affect migraines on three different levels. First, they may trigger the vasoconstriction of the blood vessels in the dura mater, reducing leakage. T

EYE SURGERY, DRAWING. EYE SURGERY, DRAWING Treatment of presbyopia by scleral expansion refractive surgery : scleral incisions. Technics of scleral expansion relies on the controversial theory that the loss of accomodation of presbyopia is not linked to the loss elasticity of the eye lens, but to the lack of space. In fact, the diameter of the eye lens increases naturally with years, so that they would not be enough space to curve and accommodate theory of Schachar, 1995. Enlarge the diameter of
