Circular Polarizers Enhance Visibility of Endothelium in Specular Reflection Biomicroscopy

Construction of an Inexpensive, Hand-Held Fundus Camera through Modification of a Consumer “Point-and-Shoot” Camera

“…Cross-polarization is a commonly used macrophotography technique and has also seen limited use in the ophthalmic field. [15][16][17][18][19] A pair of perpendicularly crossed linear polarizers (Edmund Optics) ( Fig. 2, modules 15, 16) was introduced at two locations in the optical path.…”

“…These studies have shown that cross-polarization enhances the ability to image eyes with cataract or vitreous haze, and accentuates defects in the nerve fiber layer. [15][16][17][18] Cross-polarization also improves visualization of subretinal details, including exudates and drusen. Given the intended use of this camera for retinal screening of diabetic retinopathy and macular degeneration, we believe this is a favorable compromise.…”
