The forth meeting of the Organizing Committee of the Glaucoma Society of the International Congress of Ophthalmology was held on March 10-13,1990 in Bali, Indonesia. Traditionally this meeting is attended by committee mem bers and invited experts and precedes the International Congress of Ophthal mology under the auspices of the International Council of Ophthalmology. The scientific format was structured by Stephen M. Drance, OC, MD,lVan couver (President of the Society from 1982-1990) and John Hetherington, JR, MD,ISan Francisco (General Secretary of the Society from 1982-1990). The local organization was in the very competent assistance of Josef Kadi, an ophthalmologist from Surabaya, Indonesia. Glaucoma Update IV comprises forty presentations from this meeting high lighting the latest progress in global glaucomatology. Basic research related to the pathomechanisms of the disease, new diagnostic approaches and treat ment modalities contribute to the best possible care of our patients. The ob jectives of the Society are to share the frontiers of knowledge presented in these proceeding with everyone dealing with glaucoma patients all over the world. The Society is indebted to Chibret International/Rahway, Allergan Pharma ceuticals/Irvine, and Otsuka Pharmaceuticals/Tokushima for support of the meeting and to Chibret Pharmaceuticals GmbH Munich for supporting the printing expenses of this volume.
