Abstract: Apparatus, including a tube having proximal and distal ends and an internal lumen. The distal end may bend up to 270°, and the tube may be inserted into an eye. A planar resilient strip, having proximal and distal ends, is inserted into the internal lumen, and the strip distal end is fixed to the tube distal end. A coil spring is fixed to the strip proximal end so that a coil spring symmetry axis is coplanar with the strip. A camera, mounted with the strip distal end, images the eye interior. A wire is fixed to the strip distal end, so that a predetermined force on the wire causes the tube distal end to bend by a preset angle. A magnetometer at the tube proximal end is configured, when a nonvarying magnetic field traverses it, to provide a signal that, when taken with the preset angle, indicates a camera orientation.

Abstract: The present invention relates to ophthalmic compositions and methods for the treatment of dry eye and other inflammatory ocular conditions. In particular, the present invention relates to a composition comprising an esterified anti-inflammatory lipid mediator, which is an ester of an anti-inflammatory lipid mediator that is a reaction product of the anti-inflammatory lipid mediator and a monohydric alcohol or an amide wherein the majority of the anti-inflammatory lipid mediator is present in an ester form. In this way, the compositions are substantially free of an acid form of the anti-inflammatory lipid mediators. Anti-inflammatory lipid mediators can be selected from the group consisting of polyunsaturated fatty acids (e.g.
