Most blindness is preventable and many people are unnecessarily blind. Tele-ophthalmology offers great hope to overcome this tragedy. Slit-lamp examination requires specialized skills and, therefore, needs active tele-ophthalmologic solutions to fully actualize its potential. In order to address this challenge, we have developed and tested a robotic slit-lamp system. This paper reports technical details of the system and preliminary data from a clinical trial testing this device and discusses strategies to improve the technology for a successful implementation.

Most Computer Numerical Control (CNC) machines used in Thai industry are imported. With regular maintenance, these CNC machines could last up to 10 years. After that, the owners would either purchase a new machine or upgrade the old model; the later process is widely known as “retrofitting.” However, purchasing a new CNC machine is a big financial burden for small-to-medium enterprises (SMEs) whereas retrofitting usually do not cost much less because most CNC machines are developed based on closed technology. In addition, many models are discontinued after 10 years of service making retrofitting even more costly or nearly impossible. Such problem also permeates educational institutes such as Thai Vocational Technical Colleges, which usually own 5-10 CNC milling and turning machines per institute; that amounts to 400 machines in total that need retrofitting after 10 years of usage. Most of these machines require new industrial motion control cards which had been long discontinued. Hence, an industrial grade CNC motion control prototype system based on open architecture and modular technologies has been developed as a pioneer research project for retrofitting old milling machines for Vocational Technical Colleges.

Eye tracking is widely useful in several fields especially in medical field to help human diagnosis and treatment. The proposed of this study is to develop eye tracking system using intensity measurement algorithm and apply into Ophthalmic Operating Microscope. The proposed method has been proved to be accurate, reliable, and stable.
