Retinal detachment

Concept & Etiology: How does the disease affect the ear, nose, throat, and

gastrointestinal systems in particular? How does it deviate from the definition of

health discussed in Module One?

Retinal detachment- The retina detaches and pulls away from eye tissues

supporting it.

Retinal detachment deviates from health because it can cause permanent vision

loss. The retina senses light and send signals to the brain. If the retina is damaged,

torn, or has a hole one can loss their sight.

Classification:

Exudative- “due to accumulation or serous and/or hemorrhagic fluid in the sub

retinal space because of hydrostatic factors” (AADP, 2004)

Tractional- “occurs via centripetal mechanical forces on the retina, usually

mediated by fibrotic tissue resulting from previous hemorrhage, injury, surgery,

infection, or inflammation” (AAFP, 2004)

Rhegmatogenous- occurs when a tear in the retina leads to fluid accumulation



Clinical Manifestations:

Symptoms

oBlurred vision

oFlashes of lights

oFloaters

oDarkening vision

Signs

oHole in retina

oTears in retina



Diagnostic Tests:

Eye examination

Eye ultrasound

Electroretinogram- measures the electrical activity of the retina in response to a

light stimulus

Fluorescein angiography- uses special dye and camera to look at blood flow in the

retina and choroid

Intraocular pressure measurement- measurement of fluid pressure inside the eye

Ophthalmoscopy- testing that allows doctors to see inside the back of the eye

Retinal photography- testing that provides colored images of the retina, optic nerve

and blood vessels in the back of the eye
