TRANSCRIPT
RETINAL DETACHMENT
By Diah Fauzia, S.Kep., Ns
RETINA• light-sensitive
layer of tissue • sends visual
messages through the optic nerve
• pulled away from the underlying choroid
• small areas of the retina torn =>
retinal tears or retinal breaks
• retinal cells deprived of oxygen
• if not promptly treated => permanent vision loss
SYMPTOMS• floaters - bits of
debris in field of vision that look like spots, hairs or strings
SYMPTOMS• floaters• light flashes• shadow or curtain
over a portion of visual field
• blur in vision
Can occur as a result of:
• trauma • advanced diabetes • an inflammatory disorder, such as
sarcoidosis• shrinkage of the jelly-like vitreous
that fills the inside of the eye
• vitreous liquid leaks through retinal tear and accumulates underneath retina
• retina can peel away from underlying layer of blood vessels
Factors that may increase risk of retinal detachment:
• aging - more common in people older than 40
• previous retinal detachment in one eye • family history of retinal detachment • extreme nearsightedness • previous eye surgery• previous severe eye injury or trauma
TREATMENTS
Retinal tears:• laser surgery (photocoagulation)• freezing (cryopexy)
Retinal detachment:• pneumatic retinopexy• scleral buckling• vitrectomy
PHOTOCOAGULATION
CRYOPEXY
PNEUMATIC RETINOPEXY
PNEUMATIC RETINOPEXY
SCLERAL BUCKLING
VITRECTOMY
When a surgeon injects a bubble of expandable gas into the vitreous cavity it is called:
• scleral buckling• vitrectomy• pneumatic retinopexy• photocoagulation• cryopexy
When a surgeon uses intense cold to freeze the retina around the retinal tear it is called;
• Scleral buckling• Vitrectomy• Pneumatic retinopexy• Photocoagulation• Cryopexy

Pengkajian
• Flashes of light ( photopsia)
• Floaters• Blurred vision• Sense of curtain being drawn• Loss of portion of visual field
Diagnosa
Intervensi
• Emergency RX– Apply eye patches to both eyes– Provide bed rest
• Surgical RX– Gas / Oil inserted inside eye to compress retina.
Postop – position on abdomen, head turned with unaffected eye up X 1 week
– Scleral buckling – silicone band around eye to hold choroid and retinal layers together
