Ophthalmology investigations and surgical options Flashcards
define flourescein eye drops
orange-water soluble dye
-adheres to baement membrane and highlights areas of epithelial breakdown
uses of flourescein eye drops
diagnosis of dry eye disease
identify and monitor corneal epithelial defects, corneal ulcers, corneal abrasions
state the most commonly used mydriatic and define it
tropicamide
-induces dilation of the pupil
-used to permit examination of the reitna and other deep structures of the eye
use of lissamine green eye drops
dX of dry eye disease
-used in sjogrens syndrome to rule out keratoconjunctivitis
asscertiatin proper fitting of contact lens
-look for ocntact-lens induced conjunctival staining
use of ocular ultrasonography
obtain globe length in order to calculate corrective intraocular lens power requirement
use of fundus fluorescein angiography
assess the anatomy, physiology and pathology of retinal and choroidal circulation
use of optical coherence tomography
imaging technique using low coherence light to capture a cross sectional view of each layer of the retina including the macula
use of biometry for cataract surgery
measuring the power of the cornea and the length of the eye
-then using this data to determine the ideal intraocular lens power
describe cataract surgery
Step 1: Mapping Your Eye ·
Step 2: Softening Your Cataract ·
Step 3: Making an Incision ·
Step 4: Breaking Up Your Cataract ·
Step 5: Removing lens
Step 6-replacing with artificial lens
describe retinal laser surgery
During photocoagulation, your eye surgeon numbs your eye with anesthetic eyedrops. The laser is then focused over the retinal tear or small detachment. The laser emits a beam of light that travels through the eye and burns the area around the retinal tear or detachment to create a scar
use of intravitreal injections 3
administer anti-VEGF for:
-ARMD
-diabetic retinopathy
-retinal vein occlusion
