Scheie's line as a first sign of pigment dispersion syndrome.

A 50 year old woman was diagnosed with pigment dispersion syndrome (PDS) in the right eye and pigmentary glaucoma in the left eye in a routine medical examination. A line of pigment was observed in the vitreo-lenticular interface (Scheie's line) of the left eye and with an intraocular pressure of 26mmHg. The Scheie's line (SL) develops by the accumulation of detached iris pigment in PDS and accumulated in the ligament of Wieger that forms the vitreo-lenticular union. The SL is considered a pathognomonic sign of PDS.
