Disease Lid Placement II Flashcards
Describe Myotonic Dystrophy
- Characterized by muscle wasting (mournful expression)
- Ptosis, cataracts, retinopathy, near-light reflex dissociation, low IOP
- associated with cardiac and pulmonary problems
Describe Myasthenia Gravis
- Muscle fatigue and weakness from loss of receptors
- Onset 20-50
- Signs: ptosis, diplopia, nystagmus, fatigue
Dx: Tensilon test, edrophonium (AchE improves ptosis)
Tx: Steroids, immunosuppressives, anticholinesterase and thymectomy (if associated thymoma)
Describe Dematochalasis
- bilateral condition, seen in elderly
- redundancy of skin, orbital fat profusion through septum, indistinct creases of lid
Tx: Blepharoplasty of Visual field affected
Describe Lid Coloboma
- cleft in lid caused by incomplete closure of embryonic tissue (seen in middle/medial 1/3)
Describe floppy eyelid syndrome
- loose skin where eyelids easy evert
- Signs: exposure, drying of cornea and palpebral conjunctiva, redness and papillary response
Associated with sleep apnea and keratoconus response
Tx: lid taping or surgery
You have a patient that presents with ptosis, cataracts, retinopathy, near-light reflex dissociation and low IOP. They also note that they have a history of cardiac and pulmonary problems. What is the diagnosis?
A. Myotonic Dystrophy B. Myasthenia Gravis C. Floppy Lid Syndrome D. Dematochalasis E. Lid Coloboma
A. Myotonic Dystrophy
You have a patient that presents with ptosis, diplopia, nystagmus and fatigue. They also mention that they have been recently diagnosed with a thymoma. What is the diagnosis?
A. Myotonic Dystrophy B. Myasthenia Gravis C. Floppy Lid Syndrome D. Dematochalasis E. Lid Coloboma
B. Myasthenia Gravis
You have a patient that presents with loose lids. A SLE reveals lid eversion, drying of corneal and palpebral conjunctiva, redniss and papillary response. The patient has a history of sleep apnea and keratoconus. What is the diagnosis?
A. Myotonic Dystrophy B. Myasthenia Gravis C. Floppy Lid Syndrome D. Dematochalasis E. Lid Coloboma
C. Floppy Lid Syndrome
You have a patient that presents with redundancy of skin, orbital fat protruding through septum and indistinct creases of lids.seen bilaterally. What is the diagnosis?
A. Myotonic Dystrophy B. Myasthenia Gravis C. Floppy Lid Syndrome D. Dematochalasis E. Lid Coloboma
D. Dematochalasis
You have a newborn patient that presents with incomplete closure of medial 1/3 of the upper lid resulting in a cleft. You examination reveals dermoids, strabismus and corneal opacity from exposure. What is the diagnosis?
A. Myotonic Dystrophy B. Myasthenia Gravis C. Floppy Lid Syndrome D. Dematochalasis E. Lid Coloboma
E. Lid Coloboma
What is the treatment for mysathenia gravis?
A. Steriods, immunosuppresives, anticholinesterases and thymectory (if associated thymoma)
B. Lid taping or surgery
