Retinoschisis and Choroidal Detachments

Question 1

Degenerative Retinoschisis

Answer 1

retina splits due to degeneration

more in hyperopes

Question 2

Progression of Degenerative Retinoschisis

Answer 2

begins as coalescence of cystic spaces in areas of peripheral cystoid degeneration
leads to splitting of retina into inner and outer layer
photoreceptors still attached to RPE

Question 3

Symptoms of Degenerative Retinoschisis

Answer 3

asymptomatic unless associated RD

Question 4

Signs of Degenerative Retinoschisis

Answer 4

shallow, smooth, dome shaped elevation of peripheral retina
norm inferotemporal of both eyes
stationary

Question 5

Diff b/t Degenerative Retinoschisis and RD

Answer 5

bilateral
no full thickness break
smooth, non-wrinkled surface
no shifting fluid
no fibrous membranes
no symptoms

Question 6

Mx of Degenerative Retinoschisis

Answer 6

monitored w/o treatment

Question 7

Choroidal Detachment

Answer 7

fluid accumulates b/t choroid and sclera, elevating choroid and retina
secondary to another issue

Question 8

Causes of Choroidal Detachment

Answer 8

intraocular surgery
hypotony
trauma
inflammation

Question 9

Symptoms of Choroidal Detachment

Answer 9

asymptomatic
shadow in vision
pain if fluid from hemorrhage

Question 10

Signs of Choroidal Detachment

Answer 10

dome shaped elevation of choroid and retina
smooth and immobile
shallow AC
IOP- low if hypotony, high if hemorrhage

Question 11

Topamax and Acute Angle Closure

Answer 11

discontinue topamax
lower IOP spike w/ anti-glaucoma meds
stong cycloplegic- atropine

Question 12

Uveal Effusion Syndrome

Answer 12

choroidal effusion of unknown cause in association w/ exudative RD
can lead to RPE changes and permanent reduced vision
