[en] Cicero Inacio da Silva, Guido Lemos, Eliane Mayumi Nakano and Jane de Almeida, researchers from the Laboratory of Digital Video Applications (LAVID/UFPB), the Cinematic Arts Laboratory (LabCine/Mackenzie), the Ophthalmic Dept. at UNIFESP and the Telehealth Brazil Network Laboratory (UNIFESP) participated in the last edition of CineGrid Workshop 2015, hosted by the University of California, San Diego (UCSD), with a demonstration of the first eye surgery laser shot with a camera capable of shooting 1000 frames per second in 4K definition. The camera used was a Phantom from Vision Research. The camera generates somewhere around 1 Tb of data every 3 minutes. The surgery shooting was conducted by LabCine team from Mackenzie University, in partnership with the Telehealth Brazil Networks Lab from UNIFESP. As there is still no player to view the results, the LAVID team developed a FOGO player adaptation to be able to run 1000 frames per second in 4K. The results obtained were significant, since it is possible to observe the action of the laser on the cornea of the patient, which can not be seen with the naked eye. The development of this technology will allow residents of ophthalmology area, connected to the field of refractive surgery, to observe the action of the laser and study the laser effects on the cornea. The idea is to create conditions so that the surgery can, in the near future, be transmitted to various locations, assisting in the training of medical residents in the area of ophthalmology. One of the challenges that Brazil’s team took to CineGrid 2015 is to make the transmission of a surgery captured at 1000 fps in 4K for next CineGrid San Diego in December 2016. However, the challenge is quite intense because it will require nothing more no less than 120 Gbps of dedicated connectivity connected directly to the camera, which does not yet exist between Brazil and the United States, but that could be developed soon so that this scientific connection is established in the field of telemedicine, telehealth, video collaboration and visualization advanced.
