Correlations among parameters of pentacam, iTrace, and LOCS III in assessing lens opacity.
Objectives: To investigate the diagnostic value of iTrace visual function analyzer, Pentacam 3D anterior segment analysis system and Lens Opacities Classification System III (LOCS III) in assessing lens opacity in patients with age-related cataract (ARC).
Methods: A total of 129 patients with ARC admitted to Anonymized from May 2019 to April 2021 were selected as the research objects. The degree of lens opacity was evaluated by LOCS III classification, iTrace and anterior segment analysis.
Results: The Pentacam nucleus staging (PNS) grade was strongly correlated with nuclear color (NC) (r = 0.537, p < 0.05) and moderately correlated with nuclear opalescence (NO) (r = 0.473, p < 0.05). The integrated density (IntDen) in 3-mm nuclear region was strongly correlated with NC (r = 0.548, p < 0.05) and NO (r = 0.539, p < 0.05). The dysfunctional lens index (DLI) in 3-mm area was negatively correlated with NC (r=-0.252, p < 0.05), NO (r=-0.239, p < 0.05) and posterior subcapsular cataract (r=-0.271, p < 0.05). PNS was weakly negatively correlated with the DLI in 3-mm area (r=-0.219, p < 0.05), and IntDen in 3-mm core area was weakly negatively correlated with the DLI in 3-mm area (r=-0.291, p < 0.05).
Conclusion: A combination of iTrace, anterior segment analysis and LOCS III may be beneficial in objectively assessing the opacity of different regions of the lens.
