Exam One Material Flashcards
what happens with the eyes on primary telecanthus
the inner canthi are farther apart, and the outer canthi are normal
this is neoplasm involving the Meibomian glands ; rare but highly malignant
sebaceous gland carcinoma
this is an infectious disease of the skin caused by a large DNA pox virus ; transmission by direct person to person contact
molluscum contagiosum
what are the stages of blepharochalasis
- edema stage - transient painless lid swelling with mild redness 2. atonic ptosis stage- skin assumes a reddish brown color, becoming telangiectatici and loose \3. ptosis adipose stage- involves dehiscence of the orbital septum with herniation of orbital fit into the eyelid ( steatoblepharon) ( slide 16)
this results from any process in the eyelid or orbit that restricts eyelid elevation
mechanical blepharoptosis- most COMMON ptosis seen in children and adolescents
this is a neoplasm arising from epidermal melanocytes
malignant melanoma - mgt same as SCC and BCC
what is the most common cause of eyelid laceration
domestic violence
how do we manage lid laceration
clean with betadine scrub and irrigate ; if partial thickness with no levator involvement apply Ab ointment and sterile dressing; if full thickness cover and refer to oculoplastics ; cases involving levator need surgery
this is characterized by horizontal enlargement of the palpebral fissure and the eyelid is shortened vertically ; assoc with lateral ectropion
euryblepharon - slide 39
this is an autosomal dominant dystrophy presenting in the 3rd-4th decade of life ; progressive atrophy and weakness of the hypopharyngeal and ocular muscles
oculopharnygeal dystrophy slide 23
this is defined as the inability to completely close the eyelids, resulting in ocular exposure ; caused by cicatricial ( injury), iatrogenic , and neurological
lagoopthalmos
this is a rare multisystem disorder characterized by fluid accumulation in the legs and distichiasis; occurs around puberty ; caused by mutations of the FOXC2 gene and inherited as an autosomal dominant trait
lymphedema distichiasis syndrome
Is molluscum contagiosum a reactivation infection ( ie lies dormant)
Nope
this is a change in the type of adult cells in a tissue to a form that is abnormal for that tissue
metaplasia ( shift rom benign to malignant)
how do we manage blepharochalasis
therapy during acute stages is controversial; Sx necessary for cosmesis
how does seborrheic blepharitis present
assoc with seborrheic dermatitis, bilateral, symptoms like itching, burning, grittiness,
this is a deep , dermal, nodular lesion arising from the matrix of the hair follicle ; uncommon tumor, BENIGN BUT PROGRESSIVE
pilomatricoma
this infection of the lid can spread to adjacent glands, lid tissue ( Preseptal cellulitis) or the orbit ( orbital cellulitis); rare association with necrotizing fasciitis
hordeolum
this is a condition where the eyelids cant be fully retracted; sometimes referred to as BPEI or BPES; key features of this disorder - blepharophimosis, ptosis, and epicanthus inversus
Blepharophimosis
how do we manage demidicosis
lid scrubs and Ab/steroids are inadequate ; requires removal with chemical assault ; some tx options: baby shampoo, topical metronidazole gel, mercury oxude, pilocarpine gel ( interferes with their respoiration and motility via toxic muscarinic effects) , and TTO therapy ( best therapy )_
management for blepharospasm
supportive- eye protection , lid hygiene medical - botox ( temporary relief) surgical- myectomy
management of syringoma
asymptomatic cases require no tx; medical therapy limited to case reports and anecdotal series; surgical care ( ie electrodessication)
how can we manage entropions
conservative: lube, taping the lid medical: botox for spams sx: sutures, vertical shortening procedures
this type of blepharoptosis reps a muscular etiology, typically where there is loss of muscle tone affecting the levator
myogenic blepharoptosis
