Optic tilt
WebTilt of the optic nerve head reflects the orientation of the insertion of the optic nerve at the scleral canal. It is most commonly associated with high myopia, where axial elongation and growth of the globe has led to a non-perpendicular insertion of the optic nerve at the posterior surface. Two configurations are commonly encountered: WebTilted disc syndrome (TDS), also known as Fuch’s Coloboma, is a congenital anomaly that occurs in 1 to 2% of the population. While mostly understood as a nonhereditary process, reports of autosomal dominant inheritance exist. It is characterized by inferonasal tilting of the optic disc and most commonly occurs bilaterally.

WebNov 4, 2014 · Kinematic tip/tilt mounts by Edmund Optics use the classic cone, groove, and flat constraint system (left). Three adjustment screws fit into the cone, groove, and flat; two rotational axes (turning either of the black knobs) and one translational axis (turning all three knobs equally) remain adjustable. View Image Gallery WebA fiber optic tilt senor for simultaneous measurement of 2-D tilt angle and temperature is proposed and demonstrated experimentally. The sensing head consists of two fiber Bragg gratings (FBGs) attached on a specially designed columnar pendulum. Reflection peaks of the FBGs split and resonant wavelengths shift with tilt and temperature variations. A …
