DCR & DCT
DCR (Dacryocystorhinostomy): DCR is a surgical procedure performed to treat a blocked tear duct. Tear ducts are responsible for draining tears from the eyes into the nasal cavity. When a tear duct is blocked, tears cannot flow properly, leading to excessive tearing, discharge, and possible recurrent infections. DCR creates a new pathway for tears to bypass the blocked duct, allowing them to drain normally.

DCT (Differential Color Threshold): DCT can refer to a diagnostic test or screening method used in eye care. It involves assessing a person’s ability to distinguish between different colors using color perception tests. These tests can help identify color vision deficiencies or color blindness, which may affect a person’s ability to perceive and discriminate certain colors accurately.
