Ophtalmic Genetic Therapy, the OGT,  is a system of Colourpuncture treatments of a Reflex Zone on a forehead. OGT Reflex Zone is originated from Diagnosis of the Eye, Iridology, a diagnostic assessment, which has been successfully used in Natural Therapies during the last couple of centuries. In Iridology,  body organs and systems are represented by corresponding sectors of the Iris, a coloured portion of the eye. The OGT Reflex Zone reflects the Irides on the forehead.

OGT is a 2 days CPD workshop from the International Mandel Institute.
