congential cataract
Umbilical cataracts
congential cataract
Axial fusion cataract
congential cataract
Sutural opacities
congential cataract
What is filled in the extra spaces in a sutural opacity cataract?`
albuminoid substance
Coralliform cataract
congential cataract
Persistent hyper plastic primary vitreous (PHPV)
NAME?
Mittendorf dot
congential cataract
Tunica vasculosa lentis
a form of PHPV -> may cause congential cataract
Lens coloboma
subluxated lens –> disattached from zonules
If a patient has a subluxated lens, do you want the lens to fall forward to cornea, or fall to retina?
fall to retina
Lamellar cataract (Zonular)
congential cataract
Galactosemia cataract
congential cataract
2 causes for galactosemia. Which one causes cataracts?!?!
1) (-) galactokinase –> formation of cataracts
Spherophakia (microspherophakia)
congential cataract
Lenticonus
congential cataract
Lentiglobus
congential cataract
What are senescent cataracts caused by?
decreased lens metabolism, Na+/K+ pump slows down
What are some common pt cc for senescent cataracts?
- smoky hazy vision
Cortical cataracts (cuneiform)
located in lens cortex
Causes of cortical cataracts
NAME?
Lens get bigger or smaller
pH: decr
What are the 4 stages of cortical cataract progression?
- incipient (immature)
Describe the incipient stage of cortical cataract
immature cataract
Describe the intumescent stage of cortical cataract
phakomorphic/phakogenic glc
Describe the mature stage of cortical cataract
all lens fibers are opaque
Describe the hypermature stage of cortical cataract
phakolytic
Morgagnian Cataract
type of hypermature cortical cataract
Posterior Subcapsular Cataract (PSC)
Senescent cataract (younger pt than NS)
TF: small PSC can cause large decreases in VA
yes, because the PSC cataract will lie close to the nodal points of the eye, causeing the dramatic decrease in VA
Nuclear cataract
Senescent cataract (more predictable age wise)
Brunescent cataract
sensecent
Cataract Nigra
senescent
Senescent cataract where dist VA affected more than near VA
Nuclear cataract
Senescent cataract where near VA affected more than dist VA
Posterior subcapsular cataract
Grading Nuclear cataracts
1+ mild
Grading cortical cataracts
1+ 10% pupillary space
Grading posterior subcapsular cataracts
1+ 3% capsular area

trauma induced
Luxation
trauma induced
Glaukomaflecken
disease associated cataract
Wilson’s Heptaolenticular Degeneration
disease associated cataract
What type of cataract will one find with Myotonic dystrophy?
autosomal dominant
Christmas tree cataract
disease associated cataract
What type of cataract is associated with Down’s Syndrome?
Cerulian or blue dot cataract
