LINES in Ophthalmology

LINES in Ophthalmology

• 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-Stahli’s Line= Horizontal 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 and pigment dispersion syndrome.

• Zentmeyer line = Scheie’s Line : Pigment deposition on the equatorial surface of the lens seen in pigment dispersion syndrome

• Schwalbe’s Line = Angle structure representing peripheral edge of Descemet’s membrane. A thin white or irregularly pigmented line, seen in gonioscopy, represents the peripheral margin of Descemet’s 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: seen in he 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.

• White lines of Vogt: Sheathed/sclerosed vessels seen in lattice degeneration

• Rucker’s line: Sclerosed vessels due to periphlebitis retinae seen in Multiple sclerosis

• Schlagel’s lines: Multiple yellow lines at posterior pole and periphery, arranged in clumps or linear streaks in multifocal choroiditis

• 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, characteristic of keratoconus.

• Haab’s striae – Descemet folds seen in congenital glaucoma or buphthalmos.
Descemet’s breaks or from birth trauma tend to be vertical, while the Descemet’s tears associated with congenital glaucoma tend to be horizontal or curvilinear.
