Abstract: The present disclosure belongs to the technical field of ophthalmology department and particularly relates to use of a penetrating Schlemm's canalotomy in childhood glaucoma. The present disclosure integrates 360° Schlemm's canalotomy with ab externo trabeculectomy to develop a penetrating Schlemm's canalotomy, thereby improving the postoperative success rate and reducing the adverse effects of transient elevation of intraocular pressure on visual function. This approach provides a better and more stable pressure-reduction for child patients.

Abstract: In a multiple interface, low power and lossy network comprising multiple nodes, a Network Management System (“NMS”) communicating firmware upgrades in each node of a network utilizing centralized scheduling and distributed dissemination of firmware blocks. A firmware update image is broken into blocks and transmitted throughout the network of nodes. In certain instances, every node does not receive every firmware block. The NMS receives a bitmap from the nodes indicating which of the blocks each node is missing from the update. The NMS identify particular nodes that are missing blocks and source nodes that have the blocks and are nearest to the particular recipient nodes. The NMS determines the route for the source node with the block to deliver the block to the recipient node that this missing a block. The source nodes that are identified and instructed to communicate a block to a recipient node.
