NAME?

91
Q

  1. incipient (immature)
97
Q

Describe the incipient stage of cortical cataract

A

immature cataract

99
Q

A

phakomorphic/phakogenic glc

104
Q

Describe the mature stage of cortical cataract

A

all lens fibers are opaque

107
Q

Describe the hypermature stage of cortical cataract

A

phakolytic

112
Q

Morgagnian Cataract

A

type of hypermature cortical cataract

115
Q

Posterior Subcapsular Cataract (PSC)

A

Senescent cataract (younger pt than NS)

123
Q

TF: small PSC can cause large decreases in VA

A

yes, because the PSC cataract will lie close to the nodal points of the eye, causeing the dramatic decrease in VA
