To the Editor:
In the recent article by Robert H. Fenton and William S. Hunter, "Histopathologic Findings in Eyes With Paralysis of the Oculomotor (Third) Nerve" (Arch Ophthal 73:224-228 [Feb] 1965), the authors report that in their case 1 the eye was enucleated because, in spite of ptosis, an area in the lower part of the cornea was exposed causing exposure keratitis, recurrent corneal ulceration, reduction of vision to finger counting and intractable pain. I find this observation extremely interesting as it lends further support to the suggestion that the third nerve in its passage through the orbit sends a communication to the palpebral portion of the orbicularis oculi.The orbicularis oculi is physiologically divisible into orbital and palpebral portions; the former, purely voluntary and the latter, predominantly involuntary. The two actions are separated developmentally by a time lag; the newborn squeezes its lids together but the various blinking reflexes
