TG and thyroid gland disorder: We measured a total of 20 ocular parameters (10 for each eye, including corneal radius, corneal thickness, anterior chamber depth, anterior chamber angle, lens thickness, posterior chamber length, axial length, intraocular lens power (IOL), spherical power, and cylinder power) and compared them to six indicators of thyroid activity (TSH, fT3, fT4, Tg, TgAb, and TPOAb) and between euthyroid individuals and individuals with altered thyroid function.
