Midterm Pictures Flashcards
Thinning of NFL
1) surface NFL - CRA, innermost, acquires interaxonal glial tissue posteriorly
2) prelaminar - SPCA (ZH), axons & astrocytes w/ significant incr in astroglial tissue
3) lamina cribrosa - SPCA (ZH), specialized ECM of fenestrated scleral tissue, hyaluronate in surr myelin that decr w/ age & high IOP
4) retrolaminar - SPCA (medial/lateral perioptic nerve SPCA), decr in astrocytes, acquires myelin, post limit is clear 3-4mm
1) ZH
2) SPCA - prelaminar, laminar, retrolaminar
3) CRA - surface NFL
1) zone beta - “bare”, depigmentation, broad, irregular, retraction of of RPE & thinning/absence of choroid
2) zone alpha - “
focal atrophy of the rim aka notch
Focal atrophy of the rim aka notch
Focal atrophy of the rim aka notch
Drance/flame-shaped hemorrhage - leads to loss of rim tissue over time, think NTG
Drance/flame-shaped hemorrhage
Barring - “soft” sign, vessels app to be “floating” due to lack of support from rim tissue (rim thins, leaves area of pallor)

Barring - “soft” sign, vessels app to be “floating” due to lack of support from rim tissue (rim thins, leaves area of pallor)
Bayonetting - double angulation, “z” pattern, supported at the edge
Nasal cupping - advanced glaucoma, space b/w nasal rim & BVs, color retained temporally
RNFL defect - true NFL defect assoc w/ a notch
top - fibers present
bottom - fibers not present
Bayonetting - double angulation, “z” pattern, supported at the edge
NFL defect
Neovascular Glaucoma - Rubeosis Iridis
Normal IOP unless pre-existing POAG
Neovascular Glaucoma - NVA, Rubeosis Iridis
Neovascular Glaucoma - Open-Angle Stage
Marked rubeosis and hyphema
Hallmark sign of this stage: fibrovascular membrane covering ant chamber angle & ant surface of the iris
Neovascular Glaucoma - Angle-Closure stage
Ectropion uvea frequent (presence of iris pigment epithelium on the anterior surface of the iris)
Anterior synechiae
Traumatic Glaucoma - Hyphema
Traumatic Glaucoma - Angle Recession = widening of the ciliary body
Traumatic Glaucoma - Iridodialysis = tear in the root of the iris
Traumatic Glaucoma - Iridodialysis = tear at the root of the iris
Traumatic Glaucoma - Cyclodialysis = separation of CB from SS
Traumatic Glaucoma - Iridoschisis = separation of layers of iris stroma
Traumatic Glaucoma - Iridoschisis = separation of layers of iris stroma
Traumatic Glaucoma - iritis
Traumatic Glaucoma - lens dislocation
Traumatic Glaucoma - chorioretinal trauma
1) NFL defect
2) Notch
Pseudoexfoliation Glaucoma
Pseudoexfoliation Glaucoma - Iris retroillumination defect = “moth eaten”
Pseudoexfoliation Glaucoma - Sampaolesi line = pigment deposit on Swalbe’s
Pseudoexfoliation Glaucoma - Sampaolesi line = pigment deposit on Swalbe’s
Pseudoexfoliation Glaucoma - Pigment Dispersion Syndrome
Pseudoexfoliation Glaucoma - Pigment Dispersion Syndrome
Childhood Glaucoma - Posterior Embryotoxin = thickened and centrally displaced anterior border ring of Schwalbe
Childhood Glaucoma - Haab Striae = horizontal breaks in Descemet’s
Childhood Glaucoma - microspherophakia & aniridia
Childhood Glaucoma - megalocornea
Childhood Glaucoma - bupthalmos = edema causing fuzzy corneal reflex
Childhood Glaucoma - Axenfeld anomaly = posterior embryotoxin & high peripheral iridocorneal adehsions
Childhood Glaucoma - Rieger anomaly = iris stromal thinning & holes, correctopia (pupil displacement)
Childhood Glaucoma - Peter’s anomaly
Childhood Glaucoma - NF1
Secondary Glaucomas - ICE - progressive iris atrophy
Secondary Glaucomas - ICE - Chandler Syndrome (silver hammered appearance)
Secondary Glaucomas - ICE - Cogan-Reese Syndrome
Secondary Glaucomas - ICE - Retrocorneal membrane
Secondary Glaucomas - ICE - peripheral anterior synechiae
Secondary Glaucomas - PPCD
Secondary Glaucomas - PPCD - focal iris atrophy
Secondary Glaucomas - Fuch’s - corneal guttata
Secondary Glaucomas - glaucoma assoc. w/ intraocular tumors
