Journal Article Review – The Impact of Lens Opacity on SD-OCT Measurements Using the Anatomical Positioning System (APS)

by Mauschitz MM, Roth F, Holz FG, Breteler MMB, and Finger RP

In the diagnosis and monitoring of glaucoma, eye care specialists use OCT-derived parameters like the retinal nerve fiber layer thickness (RNFLT) and Bruch’s membrane opening-minimum rim width (BMO-MRW) that support confident clinical decisions.
A recent study investigated the impact of lens opacities on RNFLT and BMO-MRW measurements based on the SPECTRALIS® Anatomic Positioning System (APS) by evaluating values before and after cataract surgery.

The SPECTRALIS Glaucoma Module Premium Edition uses the proprietary Anatomic Positioning System (APS) to provide a comprehensive and personalized analysis of the optic nerve head, the retinal nerve fiber layer, and the macular ganglion cell layer. These APS-based scan patterns are automatically matched to each eye’s unique anatomic landmarks and to the characteristics of fine anatomic structures relevant in glaucoma diagnostics.
