Lens Opacities Classification System III: Cataract grading variability between junior and senior staff at a Singapore hospital

Abstract

There was an increase in inter-observer agreement in all categories after standardization between operators.

Ultrasound techniques for lens hardness characterization: A comparison study

“…The current method used to classify the cataract is the LOCSIII, which consists in comparing the picture observed by slit lamp biomiscrospy (for nuclear cataract) or examined using retroillumination images (for cortical and posterior subcapsular cataract) with a set of standard photographs [4]. These manual grading systems have a high inter and intra-observers variability [5][6][7].…”

Comparative analysis of the nuclear lens opalescence by the Lens Opacities Classification System III with nuclear density values provided by Oculus Pentacam: a cross-section study using Pentacam Nucleus Staging software

“…The method was validated in 1993 based on slit-lamp and retroillumination images (4)(5) . The LOCS III comes with detailed instructions about its correct use showing photographic images of the cataract grade scale that can be applied to grade cataracts on a real-time slitlamp (5) .…”

Aside from being important to grade the type and severity of cataract in many cross-section and population studies (3) , the LOCS III is also important in clinical practice specially considering public healthy care systems, where a low cost classification method is required (5) .…”

“…Aside from being important to grade the type and severity of cataract in many cross-section and population studies (3) , the LOCS III is also important in clinical practice specially considering public healthy care systems, where a low cost classification method is required (5) . However, the LOCS III method is susceptible to a variety of interpretations, according to different observers, which might compromise its reproducibility (5) . Nowadays, new optical technologies such as the Pentacam imaging device (Oculus Inc., Wetzlar, Germany) have been developed to offer objective images of the anterior chamber structures including lens density evaluation (6) .…”
