The purpose of this symposium on light-coagulation is not to show the superi ority of the argon-laser-coagulation or, on the contrary, of the classical photo coagulation, but rather to see, if possible, which are the respective indications and contraindications for xenon-are-coagulation as well as for argon-laser coagulation. So, for instance, the argon-Iaser-coagulator is perhaps more appropriate to treat the lesions at and around the macula and the optic disc, but for the peripheral lesions of the retina the xenon-arc photocoagulator is surely as effective. For the conservative treatment of intraocular tumours, the xenon arc-coagula tor is beyond doubt more efficacious than the argon-Iaser-coagu lator. We were very happy to have at this symposium Professor MEYER-SCHWICKE RATH, the creator and the pioneer of light-coagulation, his coworker, Professor WESSING, and Doctor HUNTER LITTLE, one of the pioneers of the laser-therapy. We thank them very warmly for having brought to us the results of their promi nent clinical experiments. After general considerations on laser-photocoagulation, we will have a discussion on macular alterations and their treatment as well as on peripheral retinal vascular or non vascular diseases. The most important part concerns the treatment of diabetic retinopathy. Finally the prevention of complications in argon laser retinal photocoagulation will be reviewed."
The 1973 - postgraduate courses in ophthalmology held under the auspices of the Netherlands Ophthalmological Society, mark the 25th anniversary of the rebuilt Rotterdam Eye Clinic. The themes set for these courses: 'Ophthalmic Photography', 'Electro ophthalmology' and 'Echo-ophthalmology', have been chosen from a multitude of rapid developments in ophthalmology during this period. The aim was to provide the clinician with a lead in a bewildering field of apparatus and techniques and to help him in selecting methods that provide useful results without too much specialised knowledge. However, sophisticated techniques and discussion of results have been added now and then, so that the more advanced reader still finds sufficiently inter esting material in this report. This holds e.g. for the section on fluorescence-angiography which section has been extended on the base of the probability that the clinician in general practice too, has been or will be confronted with this rapidly expanding and fascinating field. The reason to bring together two methods of objective examination of visual functions i.e. electro-ophthalmology and echo-ophthalmology, is clearly due to the intimate connection between the two. In many ways these methods complement each other in providing the final diagnosis. This report does not intend to replace text books, nor to outdate treatises on superspecialised ophthalmic subjects; it simply tends to provide the clinician with a basic information on selected techniques, stimulating the reader to start using them in daily practice."
does not vary more than 1 % over the whole surface. Stimulus: The luminance of the stimuli can be regulated by means of neutral density filters. These filters are neither entirely neutral nor completely uniform, but these variations are not significant for perimetry. The maximum luminance of the stimuli is standardized at 1000 asb (316 2 cd.m-). The standard GP for kinetic perimetry has 3 neutral density filters which reduce the luminance by 0.5, 1.0 and 1.5 log units respectively. The modification of the GP for static perimetry is supplied with an additional series of four neutral density filters, which allow luminance steps of 0.1, 0.2, 0.3 and 0.4 log units. The resulting luminance values, expressed in apostilb, are given in Table I.

Until 1-1-1972 DINKHORST inserted 170 iridocapsular lenses in 158 patients. The first operation took place on 16-9--1965*. Initially, indication for the fitting of an iridocapsular lens was congenital or traumatic cataract in children, since the e~tracapsular cataract extraction necessary at that age, facilitated iridocapsular fixation (DINKHORST, 1967ac; DINKHORST & GODIN, 1967d, 1970b, 197lb, 1972d). After 1970 MANSCHOT's histopathological findings (see Chapter VIII) and the desire to reduce disloca tions and the development of ECD to a minimum induced DINKHORST to per form primary iridocapsular lens implant operations in cases with senile cataract as weH. This explains the decrease in the fitting or iris clip lens implants in favor ofiridocapsular lens implants (see Fig. 39). The distribution ofthe patients' ages in these 170 cases is, therefore, quite different from that of the 677 iris clip lens implant operations (see Fig. 40). The technique ofthe iridocapsular lens implantation is described on page 59. Numerical data are shown in Fig. 41. Noteworthy in this table are the following points: 1. The average age at operation of 30.82 years which is very low compared with the 65.80 years for the iris clip lens series, may be explained by the relatively !arge nurober of children in this series (see Fig. 40).

patients.
In The Real ABCs: A Surgeon's Analysis and a Father's Legacy, Second Edition, pioneering cataract surgeon Dr. Robert Osher reflects on his 40-year career and candidly shares that the secret to his professional success and personal happiness lies in the pursuit of "the real ABCs"-achievement, balance, and contentment. Dr. Osher was an internationally renowned surgeon and father of five when he was diagnosed with a pineapple-sized kidney cancer at age 53. Suddenly confronted with his own mortality, he resolved to write his legacy for his family, friends, and colleagues. The result is The Real ABCs, originally published after Dr. Osher's successful recovery and newly updated with his experiences and wisdom of the last decade-an inspirational story of one man's achievements as well as a prescriptive guide for finding balance and contentment. In The Real ABCs, Dr. Osher tells the story behind some of his accomplishments in ophthalmology, including the founding of the Cincinnati Eye Institute, the Cataract Surgery: Telling It Like It Is meeting, the Video Journal of Cataract and Refractive Surgery, and the introduction of groundbreaking techniques in cataract surgery. Dr. Osher demonstrates the importance of hard work and enthusiasm while admitting the inevitability of adversity and setbacks, acknowledging that his achievements wouldn't be possible without the influence of his cherished teachers, mentors, friends, and family. Throughout the book, Osher also stresses the importance of seeking balance, whether it's through nature, adventure, service, or adherence to one's principles. The Real ABCs: A Surgeon's Analysis and a Father's Legacy, Second Edition is a deeply personal story filled with universal life lessons. Ultimately, Dr. Osher shows that approaching one's career and personal life with passion and perseverance can help anyone attain a feeling of contentment and success.

This is a new edition of an innovative and popular introduction to ophthalmology. After an introduction to the anatomy of the eye and its examination, the major diseases of the eye and their management are described, followed by a problem-based introduction to clinical decision making. The contents are divided into four parts. The first contains essential anatomy and physiology. The second part describes ophthalmic diseases using a predominantly anatomically-ordered approach. The third deals with a collection of special topics, some disease-related, others covering clinical management. The final section is concerned with clinical problem solving. The fourth edition has been extensively reviewed, modified and updated to ensure its relevance to people across the world requiring an introductory text in ophthalmology. The Special Investigations chapter has been rewritten and illustrated to show how modern imaging devices help in diagnosis and monitoring. One new chapter reviews a range of global ophthalmic problems and a second provides an overview of eye problems in children. there are additional self-assessment resources available with the ebook online. Although primarily aimed at medical students this book will also appeal to those practising or studying fields closely related to ophthalmology, including optometry, orthoptics and ophthalmic nursing.
