Abstract The perception of depth in stereoscopic vision is obviously dependent on the spatial differences in the two retinal images of the view, for it is known that the act of convergence is not an essential factor in this perception. For the brain to detect these differences, the representations of the two retinas in the brain must be accurately correlated. A retinal area in one eye and another in the other eye between which, during stereoscopic vision, the brain cannot distinguish any spatial difference may be called corresponding retinal areas, and images on such areas must appear to coincide. Anatomic, clinical and experimental observations have conclusively shown that in the occipital lobes the two retinas are represented spatially. But just how precisely each retina is represented in the brain is not really known. The visual acuity of each eye is normally so great, however, especially as revealed by the alinement References 1.

It may be of some importance to state that my visual acuity in each eye, with correction of moderate errors of refraction, is 20/10 by the Snellen test, and 20/12.5 by my circle test. My ocular motor balance and torsional deviation are within normal limits, my perception of colors is normal, and my binocular perception of depth is unexcelled. I no longer have any disturbing accommodation. For over thirty-five years I have been able to unify stereoscopic photographs or diagrams by convergence or divergence without the help of a stereoscope. 4.

Abstract Nematodes of the genus Thelazia occur as natural parasites in the conjunctival sac and on the surface of the eyeball of certain mammals and birds in various parts of the world. Rarely, and probably abnormally, the human eye is parasitized with nematodes of this genus. Up to the present time only four cases of infestation of the human eye are on record, all of these reported from China. SUMMARY OF FOUR CASES RECORDED PREVIOUSLY Case 1.—A Chinaman, aged 25, with relatively slight symptoms, had six worms removed from the right eye. The case was reported by Stuckey.1 Case 2.—A Chinaman had severe symptoms ; he had marked ectropion of the right eye and excessive lacrimation ; he was very nearly dismissed as having incurable facial paralysis. Two worms were removed from the right eye. The case was reported by Trimble.2 Case 3.—A Canadian missionary in China, a man aged References 1. Stuckey, E. J.: Circumocular Filariasis , China M.

THE RELATION OF GLAUCOMA TO BLOOD PRESSUREWEINSTEIN, PAUL

Abstract The aqueous and the vitreous body in the eyeball are under a certain pressure; this pressure, developed within the eyeball, is transmitted to the semielastic sclera, and is called the ocular tension. If one disregards the condition of the sclera one finds that the normal tension is the result of a thermodynamic balance. This balance is maintained by the blood pressure in the capillary arteries and by the osmotic pressure of the blood albumins. The blood pressure causes the filtration of the aqueous, while the albuminous content of the blood lessens this filtrating pressure. The higher, therefore, the hydrostatic capillary blood pressure and the lower the oncotic pressure (the suction of the blood colloids) the greater is the ocular tension. Under pathologic circumstances (glaucoma) this balance is influenced by the osmotic pressure of the aqueous albumin and by the swelling property of the vitreous body. Besides these factors, however,

Abstract The relation of lenticular lipids to cataract has been a point of interest to ophthalmologists for many years. However, in spite of numerous investigations the lenticular lipids have not been well characterized. For this reason much confusion has arisen in ophthalmologic literature in the discussion of lipids in cataracts. Lipids in myelin forms are frequently seen in cataracts. The lipids which may give rise to these forms are: (1) the phospholipids, that is, lecithin, cephalin and sphingomyelin, and (2) the cerebrosides, namely, kerasin, phrenosin, nervone and hydroxynervone. Myelin is a term often applied to birefractive substances as well as to substances with a myelin form. In addition to unmasked phospholipids and cerebrosides many organic and inorganic substances, such as calcium salts and cholesterol esters, may also be birefractive. It is unfortunate that the term myelin is so poorly defined that it causes confusion in the ophthalmologic literature. Myelin forms References 1. Mettenheimer: Cor.-Bl. d. Ver. f. gemeinsch. Arb. z.

Abstract This paper presents an analysis of the operative results in 150 cases of retinal detachment seen in the ophthalmologic department of the Presbyterian Hospital between October 1930 and April 1, 1934. One hundred and ninety-seven operations were performed on 155 eyes; both eyes were operated on in 5 cases. Since no attempt was made to select the cases, many so-called hopeless ones were included in this group. All patients for whom the possibility of spontaneous cure had been eliminated were offered a chance by surgical intervention. This attitude was assumed with the hope that we might learn by experience more about the indications for operating for this condition. With the same idea in mind, we have analyzed the failures as well as the successes. The operative technics employed were the Gonin cautery puncture, chemical cauterization as described by Guist and Lindner and the electrocoagulation method of Walker. References 1. Shapland, C.

NEURORETINITIS ASSOCIATED WITH SYMPTOMS OF ERGOT POISONING: REPORT OF A CASEKRAVITZ, DANIEL

Abstract It has long been known that the eyes may be affected in cases of ergot poisoning, but instances of this complication are rare in this country, as I was unable to find a single case recorded in the literature. The report of a case of neuroretinitis following the ingestion of a small amount of ergot is deemed of sufficient interest to warrant the writing of this paper. Meier,1 an ophthalmologist, was the first person to record ocular complications in ergot poisoning. In 1852, there was an epidemic in the district in which he practiced in which 283 people were affected. He reported that amblyopia was a frequent sequel, but he failed to describe the fundi in these cases. In 23 cases, cataract, usually bilateral, developed, taking from six weeks to three months to mature ; unless amblyopia was also present, operative removal gave good results.

Abstract The most frequent primary source of metastatic carcinoma of the choroid is the female breast. In the cases collected by Krukenberg1 and Behr2 about 70 per cent of the metastatic lesions originated from this organ. A later estimate by Usher3 indicated a similar incidence in a larger group of cases. The lung and the stomach are next in order of frequency as primary seats of the growths, while isolated instances have been reported of tumors metastatic from the liver, the mediastinum, the thyroid gland, the suprarenal glands and the prostate.4 The case to be described differs from those previously reported in that the primary malignant growth was an adenocarcinoma of the testis. This tumor belongs to the group of teratoid tumors of the testis. These embryonal tumors in which there is a sudden overgrowth of primary elements of the germ layer are highly malignant.

Abstract In any consideration of the effect of an increase in the intensity of light on the visibility of objects the following principles should be borne in mind. Roughly speaking, objects are seen because of their size and their difference from the background. With a given physical difference from the background, i. e., a given difference in the coefficient of reflection, the apparent or sensation difference increases rapidly with an increase in the intensity of light. This difference is greater in the case of white on black or light objects on a dark background than for black on white or dark objects on a light background. Whether there is also an effect on the apparent size of the object has not yet been fully determined. It is well known that an increase in the size of the object functions in some unknown relation as an increase of brightness, but the converse References 1. Ferree, C.

Abstract The cholesterol content of normal and cataractous crystalline lenses is an old and unsettled question. Most of the early work was fragmentary and qualitative. This paper includes a discussion of the literature and a report of data from analyses of more than one hundred cataractous lenses which, before removal, were studied with the slitlamp microscope, then extracted by the intracapsular method and carefully analyzed. Von Graefe,1 in 1854, was the first to see and recognize cholesterol in the lens. In 1857, Mettenheimer2 reported having seen double refractive substances, which he regarded as myelin, in cataractous lenses and also in the normal lens of a 28 year old woman. From one comparatively clear lens he succeeded in isolating myelin and cholesterol by boiling in alcohol. Eleven years later, Kühne3 reported the finding of fat and cholesterol in the normal lenses of oxen, with greater quantities in References 1. von Graefe, A.: Seltene Fälle von Cataract , Arch. f.

Abstract Monocular nystagmus in an infant, without any known associated pathologic state, is of sufficient rarity to warrant reporting. The report is particularly justifiable since the study of the case has led to the belief that nystagmus in children is caused by the same fundamental set of conditions as that in miners and that produced experimentally in young dogs, that is, by living for a long period in poor and inadequate light. Furthermore, the immediate beneficial response of the nystagmus in this case to the use of homatropine may lead to further trial and study of this drug as a therapeutic agent in the treatment of nystagmus in children. A review of the literature shows that unilateral nystagmus without any demonstrable pathologic condition producing it or associated with it is very rare. That of horizontal type is remarkably rare. Peter1 stated that monocular nystagmus "as a rule" is of vertical References 1.

CHRONIC UNILATERAL HYPERTROPHIC CONJUNCTIVITIS: A Case for DiagnosisFine, Abraham

Abstract The following unusual case of chronic unilateral hypertrophic conjunctivitis presents many features of considerable interest. The unfortunate termination in complete loss of sight marks the problem as a practical one, worthy of more than mere academic consideration. Despite extensive pathologic studies conducted both at the Manhattan Eye and Ear Hospital and at the Knapp Memorial Eye Hospital, the condition remains undiagnosed and offers a challenge to ophthalmologic knowledge. REPORT OF CASE History.—A man, aged 32, a dressmaker, had a cold in the head in May 1932, which lasted about ten days and was associated with redness, itching and tearing of both eyes. The condition resembled in some respects the autumnal attacks of hay fever which the patient had had for the past five years. There was no fever, chills, vomiting or other constitutional disturbance. He gave no history of trauma to the eye or of contact with References 1. Fuchs, E.: Tuberculosis of the Conjunctiva , in Text-Book of Ophthalmology , ed. 8, Philadelphia, J. B.

CONTACT GLASS FOR USE IN OPERATIONS ON RETINAL DETACHMENTKlein, Miklos

Abstract In the present method of treatment of retinal detachments by diathermic punctures it is important to control the placing of the perforations by simultaneous observations with the ophthalmoscope. It is therefore essential that the transparency of the cornea should not be impaired during the operation, otherwise ophthalmoscopy is impossible. To obviate the drying of the cornea a Zeiss contact glass has been applied to the globe. The use of the regular Zeiss contact glass, however, entails several difficulties: One must dispense with the directive suture at the limbus, and one must perform the measurement of the chord distance from the limbus against the glass. Also, if the operative field lies nasally or temporally, the application of the Zeiss contact glass is impossible because the wide scleral part touches the palpebral angle when the globe is turned aside, and the glass is simply lifted up. I have attempted to

Abstract The Šafár̂ and Walker electrodes have been in use a sufficient length of time to prove their worth. However, they have certain shortcomings: 1. Some of the Šafár̂ electrodes consisting of one, two or three points are difficult to handle. They slip from the hold of the forceps and may get lost in the wound or become caught in the meshes of gauze or cotton. 2. The hard insulating varnish covering base, into which the short needle points are fastened, becomes brittle, cracks and peels off, and the danger of losing these particles of varnish in and outside the eyeball, though remote, is always present. 3. The thorough cleansing of the points is almost impossible unless much time and care are devoted to this work. 4. The sharpening of the points is very difficult. 5. Ideal sterilization by high temperature or a Bunsen burner is not practicable. 6. Finally, the References 1. Walker, Clifford: Retinal Detachment , Am. J. Ophth. 17:1 ( (Jan.) ) 1934. 2.

CHRONAXIA AND THE EYEMAYER, LEO L.

doi: 10.1001/archopht.1935.00840020114014
Abstract A new doctrine of physiologic investigation has appeared. It concerns more especially the activity of muscles and nerves in relation to electrical stimulation. The groundwork was brought forth by Lapicque1 in his experimentation with nerves and nerve-muscle preparations. Of more recent date has been its practical application in neurology. Now its premises are creeping into ophthalmology as they relate to the musculature of the face, the extra-ocular muscles, the instrinsic muscles of the eye and, finally, the retina and optic pathways. The term ``chronaxia'' may be defined as the time during which a current of twice the threshold intensity (i. e. two times as strong as the constant current which causes a minimal stimulation) must flow to produce a minimal stimulation. In this brief outline I shall attempt to explain in simple language the doctrine of chronaxia as it concerns the eye. An introduction into this subject References 1.

Abstract It has been customary in Germany to give from time to time a postgraduate course (Fortbildungskurs), lasting one week, in a university town, in which the ophthalmologic problems of the day are presented in lectures and in clinical and operative demonstrations by the ophthalmologists and other members of the medical faculty. This time the meeting was held in the celebrated university town of Freiburg. These lectures have appeared in printed form, so they are available for those who did not take part in the course. It is interesting to observe what subjects were selected as suitable for this course. Most of the lectures were given by Löhlein, the director of the eye clinic, and by Wegner, his first assistant. Löhlein spoke on glaucoma, new medical and radiation therapy, optical correction and contact glasses, while Wegner discussed ocular tuberculosis, fundus diagnosis of increased blood pressure, operations, questions

Abstract In this third edition Duke-Elder has written practically a new book, which means the addition of many new subjects and the omission of subjects in which there have been few recent advances. Thus the purpose of the book, namely, to acquaint the senior student with those facts which are at present situated somewhere between graduation from the literature and adoption by the textbook, is admirably fulfilled. The subject matter is divided into a part on physiology and a part on diseases of the eye. The former treats of the vascular circulation, the intra-ocular fluid, the vitreous body, the intra-ocular pressure and the effect of drugs on the eye ; and the latter part considers intra-ocular infections, the ocular pigment and intra-ocular tumors, the conjunctiva, the cornea, the retina, cataract, glaucoma and sympathetic ophthalmitis. Each chapter ends with a list of literary references. This important work should be read by

Wilmer, the development and comparative anatomy of the human lens are treated in an authoritative manner by Ida C. Mann. Clapp then takes up in turn the anatomy, nourishment and growth, physiology, chemistry, congenital anomalies and pathogenesis of the lens. The clinical discussion occupies the second half of the book and begins with a description of the various types of cataract. After a chapter on the nonoperative treatment, the operative treatment of the various forms of cataract is gone into thoroughly, from the preparation of the patient, with an outline of the various operations, to the after-care. Clapp has accomplished his purpose of writing a comprehensive work on the lens, and he has done this well. A comprehensive study is timely, as, though there have been many books on the clinical and operative phases of cataract, there has not been an up-to-date
