Abstract Like the old woman who lived in the shoe, we find ourselves giving sustenance to an apparently innumerable array of viruses whose recently affixed names are strange and whose behavior is as unpredictable as that of any younger generation. As Dr. John Enders recently commented in citing the multiplicity of these agents, "At this point I'm sure you are tempted, as I am, to cry out in anguish, like Macbeth upon seeing the vision of Banquo's endless descendents 'Will the line stretch out to the crack of doom?' " But these virile bits of organic matter are fascinating, and equally interesting is the scientist's attempt to cope with and catalogue them. Let us now survey some of the problems contributed by these more recently explored miseries of man and begin (promiscuously) at the bottom. Although the enteric or enteroviruses may be isolated from many sites of the gastrointestinal tract, as well

Abstract Photosensitization is the induction of a biologically reactive state by wave lengths of light that are ordinarily innocuous. The tissue reaction to ultraviolet radiation longer than 320 mμ is basically similar in the photosensitized state to that of the abiotic range but is modified by the greater penetration of the longer wave length radiation and therefore potentially more hazardous. Elsewhere in this issue is a report of cataract induction in mice photosensitized to ordinarily harmless radiation by repeated injections of 8-methoxypsoralen. The implications of this for human beings are thought-provoking. The ultraviolet light was in the range to which all of us, save those in the most smogged out communities, are daily exposed. The sensitizing agent, one of the furocoumarine family, is currently used topically and systemically for vitiligo and for tanning of the skin. The case for human cataractogenesis, however, is far from proved. The amount of psoralen given

Abstract At the Royal Institutes for the Blind in Denmark 7 cases of congenital bilateral pseudotumor of the retina have been observed in 4 generations of the same family; the first case was diagnosed in 1860. The disease is transmitted by X-chromosomal inheritance through females to males. All the affected patients were totally blind from birth, and the uniform clinical picture in all the cases was characteristic. Five later developed severe deafness, and 4 were mentally deficient. No other malformations were observed in this family whose members have been followed through 7 generations. The pedigree of the family, which comes from the small isolated island of Bornholm in the Baltic, is shown in Figure 1. Report of Case The subject is an 8-month-old Danish boy (marked p in Fig. 1), patient of Dr. K. Dreisler.His mother had negative serological reactions for syphilis and toxoplasmosis. The pregnancy and delivery were References 1. After we submitted this paper for publication we found a paper by Ash (1922)11 in which he describes a family with hereditary microphthalmia in 11 members in 3 generations. In 1940 a histopathological examination was reported by Whitnall and Norman11a dealing with both eyes from one of these cases. The similarity to our case is striking. 2.

Abstract A fall in intraocular pressure in the contralateral undisturbed eye as a result of massage and trauma has been known since 1878 when Pagestecher1 described his observations. The term "ophthalmotonic consensual reaction" appears to have been coined by Weekers2 in 1924. The consensual fall in intraocular pressure accompanying tonography is well annotated,3-6,11 and its importance lies in the fact that the change in ocular dynamics which must occur to produce it may lend itself to study and analysis of the neurovascular reflexes subservient to the homeostatic mechanisms maintaining normal intraocular pressure. The literature suggests that the consensual fall occurs in most people and is of the order of 1-4 mm. Hg.3 The exact mechanism is not clearly worked out, but in animals Prijot and Stone4 found a decrease in flow of aqueous humor in the presence of unchanged facility of outflow, scleral rigidity, and constant References 1.

Abstract A previous communication by the authors related the development of posterior subcapsular cataracts (PSC) to long-term high dose corticosteroid therapy,1 and a subsequent paper2 discussed the appearance and differential diagnosis of these cataracts. This report includes additional patients with the same complication and follow-up data on patients previously and presently reported. Methods and Material Collection of data and examination were carried out as outlined in previous papers. The diagnosis was established in all cases by biomicroscopy; patients with other ocular pathology which might be related to PSC were omitted from the series.This series consists of 95 patients. Twentythree of these had rheumatoid arthritis not treated with corticosteroids and thus served as controls; none of the controls developed PSC. Seventy-two patients, 28 of whom have not been reported previously, were treated with corticosteroids; of these 72 patients, 30 developed PSC (Table 2).

Abstract It is universally recognized that retinal breaks play an essential role in the causation of idiopathic retinal detachment; therefore, the term rhegmatogenous * retinal detachment has been coined to denote a detachment resulting from a retinal break. The exact conditions which bring about retinal breaks are still unclear, and it must be admitted that their pathogenesis is largely a matter of speculation. There are 2 approaches which seem to offer interesting possibilities to the problems of retinal detachment. First, it is hoped that our increasing knowledge of the metabolism of the vitreous body will permit a study of the biochemistry of retinal detachment on the molecular level. This would provide a clear understanding of the biochemical mechanisms which culminate in the production of retinal breaks and subsequent retinal detachment. It may eventually be determined that a whole group of chronic conditions are related to the type of metabolic dysfunction which causes References 1. Rhegmatogenous comes from the Greek [unk][unk]γμα, which means "break" or "solution of continuity," and γ[unk]νος which means "origin." 2. Schepens, C. L.: Progress in Detachment Surgery , Trans.

Abstract Only 8 cases of congenital ocular motor apraxia have been reported. All have been described as occurring in males.' The distinguishing features of this syndrome include: (1) absent or defective voluntary horizontal eye movements with retention of normal random versions; (2) characteristic jerking movements of the head to break fixation; (3) absent or defective quick phase of the optokinetic response with; (4) controversion of eyes when the head is turned on the vertical axis; (5) reading difficulties. Acquired forms of this syndrome were described as early as 1908 by Wilson, and in 1909 by Balint; however, recognition of the congenital variety dates back only to 1952, when Cogan reported 4 cases in males.2 There have been at least 10 acquired cases reported3 and 8 of the congenital variety.1,4 Cogan has knowledge of other unreported cases.5 Thus, the condition may not be rare, but only relatively unrecognized.

Abstract Treatment of Pseudomonas corneal ulcers has been disappointing with encouraging results appearing in the literature only within the past 5 years. Morelli's1 review of the literature up to 1922 shows a story of almost unanimous failure, with 23 enucleations, 14 leukomas, and 1 nebula. Moorman's2 review of 24 cases from 1922 until 1939 showed 12 eyes enucleated, 9 with vision 20/200 or less, and only 3 with vision better that 20/200; whereas 25 cases from 1939 until 1955 treated with sulfa compounds or antibiotics other than polymyxin B sulfate resulted in 10 enucleations, 9 eyes with 20/200 vision or less, and 6 eyes with vision better that 20/200. Of 11 cases treated by Moorman with polymyxin B or E sulfate. one eye was enucleated, 7 had vision 20/200 or less, and 3 had vision better than 20/200. There were 8 cases of corneal ulcer due to Pseudomonas reported References 1. Morelli, E.: Contributo allo studio del cheratoipopion da bacillo piocianico , Arch. Ottol. 29:285, 1922. 2. Moorman, L.

Abstract The inflammation of the canaliculus, although a rare disease, constitutes a clinical entity in the form of suppurative canaliculitis also known as blennorrhea of the canaliculus; the organisms found to be responsible have been staphylococci, gonococci, pneumococci, Bacillus pyocyaneus, diplobacillus, sarcinae, and Micrococcus tetragenus (Duke-Elder, 1952). A purulent inflammation of nonspecific origin has also been described by Elschnig (1909), Hoitasch (1922), Wiltschke (1924), Stock (1924), Theobald (1926), Morana (1929), and Herrenschwand (1931). Since its original description by von Graefe (1854-1855), fungus infection of the canaliculi has also become well recognized. But spirochaetal infection of the canaliculus leading to suppurative canaliculitis is an extreme rarity and perhaps has not been reported up till now.

Abstract Introduction It is proposed in this paper briefly to review the surgical procedure of keratoplasty, rapidly to note the stages of development, to comment on its present status, its possibilities, and its limitations, and to point out in what directions we may expect future progress with suggestions as to how we should best apply our efforts to attain these desired ends.Until recent years the efforts of the surgeon or specialist working in the field of tissue transplantation have been preoccupied with instrumentation, technique, and clinical observation of the patient. This is not to be decried, since it is quite obvious that mechanical improvement in corneal grafting techniques and instrumentation is largely responsible for the present high level of achievement in this area. When, however, we come to interpretation of clinical problems, as for example, "graft sickness," speculation has run wild and there has been relatively little serious or scientific References 1.
