Collagen corneal shield has recently been increasingly applied as a corneal badage lens or drug delivery system, because of its usefulness in treating various ocular surface problems. Therefore, we put our focus in this review on treatment procedure for corneal ulcer in dogs and cats using the collagen shield impregnated with ofloxacin and the resulting clinical findings. In the final analysis from some clinical trials, this collagen shield impregnated with ofloxacin is found to be one of the useful therapeutical materials for corneal protection and/or reconstructive procedure in case of corneal diseases.

In the Constitution of the International Society of Veterinary Ophthalmology, our Japanese Society of Comparative and Veterinary Ophthalomology, JSCVO, and the Japanese College of Veterinary and Comparative Ophthalmogists, JCVCO, were registered as Members of the Executive-Advisory Committee of the Society, ISVO, at the Santa Fe Meeting held in the fall of 1997.

Like the above two Japanese organizations, JSCVO and JCVCO, the ISVO also has a policy to research ocular troubles of all animal species, and to be open to all veterinarians and scientists worldwide.

The former presidents of the ISVO, Drs. Magrane, Blogg, Barnett, Aguirre, Peruccio, Narfström, Stades and Peiffer Jr., made great efforts to realize the Society's purposes. The members of ISVO, who numbered about 100 persons in the early 1980s, are over 500 at present.

We should be mindful of the service and sacrifices of above past presidents for the Society's activities as well as the services of other past officers, of all former members of the Executive Committee, and of the Editer-in-Chief of the “Globe”, of “Veterinary Comparative Ophthalmology”.

In the next century, young active ophthalomologists in Mid-East, East Eurasia, South America, Africa, and the Pacific Rim Area will increase remarkably.

The ISVO has a brilliant future as a leader in veterinary research and the clinical field, and has an obligation as to lead this scientific field internationally.

As a Member of the Executive Committee of the Society, I have great expectations for this.

Finally, we have a dream that some day in the 21st century, young Dr. Frederico Peruccio in Italy will lecture on the development of ISVO activity in some place on this globe.

This study reports the outcomes from the tests conducted with a novel, simple gonioscopic method using a +20D condensing lens to examine the iridocorneal angle or the anterior chamber in fifteen dogs and five cats. When the lens was placed on the lateral area of corneal surface near the limbus, a half or less of all circumference of the iridocorneal angle could be observed. Almost no animal showed any resisting behavior against this treatment procedure. In addition to abnormal anterior angles, the focal lesions on the iris, and precipitation of fibrin in the anterior chamber, and swelling of the lens were able to be detected. Accordingly, it was confirmed that this method provides one direct way of assessing the abnormalities in the anterior chamber practically.
