Lecture 5 Flashcards
Horse shoe tear is defined as
Full thickness break + Vitreoretinal traction.
Horse shoe tear is associated with
Vit heme, shafers.
Horse shoe tear usually occurs next to
A strong adhesion like cystic tuft or lattice.
Risk of horseshoe tear
40+, myopia, lattice, aphakia, trauma
Location of retinal dialysis if associated with trauma vs genetics
Trauma- SN
Genetics- IT
How to treat retinal dialysis if there is a detachment vs if there isn’t
Detach? Surgery
Not detached? Laser or cryo
Giant retinal tear is a full thickness break that involves more than __ degrees of ora zone
90
Giant retinal tear leads to an inevitable
Retinal detachment due to vitreotraction at edge of tear.
What has a taco shell appearance
Giant retinal tear
Giant retinal tear risks
Myopia / lattice Male x 4 bc associated with trauma chorioretinal degeneration Surgery WWoP
Management for giant retinal tear
Send to retina ASAP. Poor prognosis. Monitor other eye for same thing, especially in at risk group
Another name for choroidal detachment. Definition
Effusion
Separation of choroid from sclera due to supraciliary space filling with serous or blood.
Characteristics of a serous filled choroidal detachment
Clear Low IOP (4-6mm) Shallow AC (use cyclo to open) AC cells and flare No pain Will resolve as IOP increases, better outcome than hemorrhagic
On B scan, looks dark
Causes of low IOP/serous choroidal detach
Surgery, RD, Trauma, rapid decompression, meds, nanophthalmos, infection
Meds that can lower IOP too much
Sulfonamides, tetracycline, diuretics, SSRIs
Characteristics of hemorrhagic choroidal detachment
Yellow/brown High IOP Worse outcome than serous Associated with pain bc high IOP Redness, shallow AC, cells and flare
Causes of high IOP/Hemorrhagic choroidal detach
Neoplasm in choroid
Sturge weber causing choroidal hemangioma
Another name for intermediate uveitis
Pars planitis
Intermediate uveitis is the inflammation of
due to what
Vitreous and peripheral retina
Many causes- could be infectious or non infectious
Demographics of intermediate uveitis
Recurrent over 15-30 years
Bilateral 70% of the time
Ages 15-40
intermediate uveitis appearance
Mild ant chamber rxn without the usually anterior uveitis symptoms
Vit inflammation/cells
Snowballs inferior
Snowbanking- exudative plaque/fibrovascular
Peripheral peri phlebitis (25%, more common in MS pts)
3 treatments of rhegmatogenous detachments and success
Pneumatic reinopexy- laser
scleral buckle
Vitrectomy
90% success, 55% have 20/50 VA
Macula off rheg detachment. When should you get surgery
Visual outcomes do not change if surgery is performed within 7-10 days of onset.
