II Lecture Chapter 16 Identification: Eye Damage pp 363

diplopia

the perception of two images of a single object; also known as double vision

strabismus

crossed eyes

a pathological condition involving a misalignment or deviation of the eyes that prevents them from working simultaneously to track visual objects

three types of strabismus

esotropia-the affected eye turns medially (crossed-eyes)

exotropia-the affected aya turns latterally (walled-eyes)

hypertropia-the affected eye turns upward

what procedure is used to correct strabismus

recession or resection of the eye

recession more more effective on vertically acting eye

resection more effective on lateral rectus

why would the adjustable suture technique for surgery be beneficial?

adjustable suture technique in adults with diplopia allows more accurate alignment and placement of the field of vision

what layers of the eye are incised and must be closed at the end of the procedure

the conjunctiva, the fascia, and the muscle

identify the key instruments and supplies for the procedure

headrest

loupes

marking pen

Xylocaine with epinephrine

antibiotic ophthalmic ointment

lacerations of the eye: what is the purpose of the Veirs rod?

10-mm diameter rod made of stainless steel

placed through the laceration and the canaliculus is approximated with nonabsorbable suture around the rod
