GPT and cataract: A selection of other, less commonly evaluated, prognostic factors were investigated in individual studies, including: physical activity (WESDR: Cruickshanks 1995); myopia and ocular perfusion pressure (WESDR: Moss 1994a); alanine aminotransferase, haemoglobin, white blood cells, and platelets (Lee 2021); peripheral circulatory disorders (Gange 2021); peripheral lesions (Silva 2015); absence of Achilles tendon reflexes (Nelson 1989); cataracts (Verdaguer 2009); prothrombin time (Gui 2013); and oscillatory potential (Simonsen 1980).
