Opening feedback of the President, second ISVO, Professor G.M. Breinin, M.D. The research of visible methods is definitely detailed as a medical distinctiveness, in­ corporating the disciplines of physics, chemistry, body structure, and psycho­ logy. Diagnosing and correcting problems of the visible procedure in those final twenty years of the twentieth century has introduced we all into shut prox­ imity with desktop sciences, laser expertise, the marvels of digital microcircuitry, and the remarkable advancements in optical fabrics. Dur­ ing the process this assembly we will be listening to approximately how those varied applied sciences can have interaction with each other, and we will become aware of that such interplay might produce new diagnostic instruments and new optical units. we will additionally research that the optical traits of the attention switch in the course of existence, generating refined and complicated adjustments in imaginative and prescient. On behalf of the participants and organizing committee of the yankee devote­ tee on Optics and visible body structure and our co-sponsoring association, the Optical Society of the United States, I welcome you to this moment symposium on visible optics. the 1st symposium happened in Japan in 1978 and, just like the pres­ ent one, was once a satellite tv for pc assembly of the overseas Congress of Ophthal­ mology. The 3rd symposium during this sequence will ensue in Italy in 1986 as a part of the following consultation of the foreign Congress of Ophthalmology.

Some experiments were performed to demonstrate the feasibility of this method. This method can provide a position of visual axis in object space passing through the entrance the entrance pupil plane. The accuracy of this method is the order of 2 x 10-2 mm at the entrance pupil plane, and 7 x lo-2a in We also suggest a technique for adarc for the measurement of the angle justing the eye, which can be applied to refraction test and photokeratometry and so on. This method also may be available to the alignment and fixation device, measuring the visual direction and the angle of the eye, center of rotation (sighting center), etc.

Kobayashi, and Y. , Nakahara-ku, Kawasaki, 211, Japan Introduction Remarkable progress has been made in the design of automatic refractometers, particularly because of advances in electronics and microcomputers. Various types of automatic refractometers incorporating the advanced technologies have been introduced and they have increased the demand for an instrument that enables us to measure refraction with high reliability.
