Abstract: Methods and formulations for treating ocular pain, including nociceptive and neuropathic ocular pain, are disclosed. The formulations include ambroxol or a chemical derivative thereof. The methods and formulations selectively inhibit the Nav1.8 nociceptor which allow sensation while relieving pain. The formulation and method provide effective and safer topical ocular pain control than current topical analgesic formulations and methods.

Abstract: Formulations for treating ocular surface diseases, such as dry eye disease, and related methods are disclosed. The formulations include and effective amount of ambroxol or a chemical derivative thereof (for example, bromhexine) that may be dispersed in a carrier and may optionally include a biocompatible polymer to provide extended release properties.

Abstract: Embodiments provide a method for adapting to screen orientation switching during a video call and an apparatus. The method includes: during a video call between a first terminal and a second terminal, detecting, by the first terminal, screen orientation switching of the first terminal; after it is detected that the screen orientation switching of the first terminal occurs, sending a switched screen orientation to the second terminal; and receiving a video stream that is sent by the second terminal according to a video requirement corresponding to the screen orientation.
