·
Arlt's Line = conjunctival scar in sulcus subtarsalis in Trachoma.
·
Ehrlich-Turck Line =
linear deposition of KPs in uveitis
·
Ferry's
Line = corneal epithelial iron
line at the edge of filtering blebs.
·
Hudson-Stahil Line=
Horizonatl corneal epithelial iron line at the
inferior one third of cornea due to aging.
·
Khodadoust Line = corneal graft
endothelial rejection line composed of
inflammatory cells.
·
Paton's Line = Circumferential retinal
folds due to optic nerve edema.
·
Sampaoelesi line = Increased
pigmentation anterior to Schwalbe's line in pseudoexfoliation syndrome.
·
Zentmeyer
line (Scheie's Line): on the
equatorial surface of the lens pigment dispersion
syndrome
·
Schwalbe's Line = Angle
structure representing peripheral edge of Descemets
membrane.
·
Stockers Line =
Corneal epithelial iron line at the edge of pterygium
·
White
lines of Vogt =
Sheathed or sclerosed vessels
seen in Lattice degeneration
·
Fingerprint lines: The map-dot
fingerprint dystrophy
·
LASIK Iron Line:
After LASIK for myopia, the central corneal curvature is flatter than before
surgery. The tear film distribution is therefore altered, allowing some pooling
centrally. This pooling can cause iron deposition in the central epithelium. A
similar effect can be seen after steeping of the cornea from treatment of hyperopia. In the case of hyperopia,
a pseudo-Fleischer's ring iron deposition
can be seen. These iron lines do not affect vision.
·
Vogt's striae occur centrally
in a patient with keratoconus. By applying digital pressure on the
eye while looking through the slit lamp, these striae
in the deep cornea, mostly Descemet's membrane,
disappear, which is charac teristic of keratoconus.
·
The Descemet's breaks
or Haab's striae from birth trauma tend
to be vertical, while the Descemet's tears associated
with congenital glaucoma tend to be horizontal or curvilinear.
·
Ring Keratitis: The hallmark of Acanthamoeba
keratitis
·
Kayser-Fleischer's
ring: Wilson's disease
·
Corneal rust ring: A small, reddish
brown, circular opacity remained in the cornea after the removal of an iron
foreign body.
·
Coats' ring: remnants of a foreign body.
The remnants are fine iron deposits in the cornea.
·
Fleischer's ring:
visible all around the base of cone in Keratoconus
·
Pseudo-Fleischer's
ring: iron deposition can be seen in Hyperopia
·
Soemmering's
ring: early opacification of lens capsule in
cataract
·
Vossius' ring: on lens in concussion
injury to eye
·
Weiss ring: epipapillary
glial tissue torn from the optic disc in Posterior
vitreous detachment (PVD)
·
Double ring sign: with the peripheral
margin of the encircling ring corresponding to the border of a normal-sized
optic disc. Seen in Hypoplasia of the Optic Disc.
