Ophthalmoscopic Examination Of Sixty Insane Patients in the State Asylum at Utica. BY HENRY D. NOYES, M. D. [ From the American Journal of Insanity for January, 1872.] Ophthalmoscopic Examination OF SIXTY INSANE PATIENTS IN THE STATE ASYLUM AT UTICA. V. By the request of Dr. Gray, I examined witli the ophthalmoscope 60 patients taken from the wards of the asylum. Of the nature of their diseases I was quite ignorant, and often did not know whether the persons examined were insane. I had no preconceived notions of what lesions to expect, and simply de- scribed in brief notes the appearances which I saw. In most cases the pupils were dilated with atropia, and in almost all cases the examination was made by the upright image. Minute retinal changes can only be seen by this method, and the region of the yellow spot can be well seen only with dilated pupil. I am in the habit of looking with relaxed accommodation, and only require such a corrective glass as the patient’s re- fraction may demand. When any glass is needed, the fact is stated in the notes. I have endeavored to describe the facts just as they were, and have inserted statements which are not im- portant to the question of diagnosis, viz: the existence of physiological excavation, the accidental pigmentation of the choroidal border of the disc and other points which an ophthalmoscopist would at once know to be- long to the variations consistent with health. In the retina I speak in many cases of the occurrence of minute specks sometimes called pin points—usually found near the yellow spot. They may be in it, directly around it, or between it and the nerve. They are so 2 fine as only to be seen with the greater magnifying power of the upright image. They are bright in color, whitish or yellowish, but are not the lesions seen in retinitis from Bright’s disease, nor in any recognized disease. I have seen the same specks in other eyes, and have not found that they produce any impairment of sight; but I can not assert that they are not precur- sors of lesions which may injure sight. They certainly appear most often in states of retinal congestion, and they are found in cases of asthenopia. If they are to have any value attached to them, it would be that they indicate hypersemia. The advancement of the small vessels nearer than normal to the macula, is an un- doubted sign of hypersemia. So, too, striation of the edge of the optic nerve and of the adjacent retina is due to oedema of the tissue. But I do not forget that there is striation wdiich is wholly physiological, even when not amounting to the degree recognized as due to opaque or double outlined nerve fibres (marie- haltige nervfa-sern.) In most cases the striation de- scribed is of the pathological variety. As to hyper- semia of the nerve, I am quite aware of the great dif- ferences which characterize the healthy state of the nerve in different persons, and I am accustomed to look quite as much for change in transparency and texture as for modification in hue. The significance to be given to pulsation of the veins upon the disc is yet a moot question. It has been regarded as a sign of arterial and intra ocular tension. It habitually occurs with quicken- ing of the respiration, and that may have induced it in some of the timid and excitable patients. It has been taken as a sign of cerebral anemia, and made much of in epileptic cases to determine the vascular state of the brain. We are not yet clear on this subject. The number of cases which are here tabulated are 3 wholly insufficient for a basis of general deductions. These are but a handful to what must be collected be- fore such generalizations can be made. I have not, however, hesitated to point out facts which appear, on scrutiny of the cases, to be noteworthy. Small though the material is, it may do something to help us understand better a most intricate subject. For an account of similar cases, I would refer to All butt’s recent work on the ophthalmoscope in brain disease. GENERAL PARESIS, 11 cases. In all tliese cases, with the exception of two, there is hyperasmia and infiltration of the nerve and retina. The striation of the retina, near the nerve, is often ex- tremely pronounced, and may render the edge of the nerve hazy and indistinct. The nerve is often opaque in texture, or may be of a slatey hue. In one instance (5,) the nerve is found pallid, and doubt is expressed whether this may not correctly be called a sign of atrophy. It would not be easy to decide the point without testing the sharpness of sight, which wms not done. The hue of the opposite nerve and its ill-defined edge would favor this opinion, because its congestion would be likely to issue in just such pallor as is describ- ed in the left eye. Case 11 also presents these tokens, as if it were now in a secondary stage following con- gestion. The uniformity in the aspect of the fundus oculi was so considerable that I soon learned to suspect from ophthalmoscopic appearances what was the nature of the patient’s malady. I am not to be understood as saying, that I could thus diagnosticate general paresis. But the value of this observation will appear when, in inspecting other forms of brain disease, considerable discrepancies are noticed. 4 1. Man—Admitted August 8, 1871, aged 40.

In 12 tlie optic nerve and retina exhibited hyper- aemia or infiltration. In six they did not. The causes assigned to the mental state in the first cases were, epilepsy 2; intemperance 3 ; masturbation 3; exces- sive sexual indulgence 1; phthisis 1; ill-health 1; not given 1. Duration had been from six months to a year in 3; for one year in 2; for three years in 2; for five years in 2; not stated 3. Of the six cases not liyperaeinic the causes of mental state were, epilepsy 1; hemiplegia 1; intemperance 1; not stated 3. Duration, one year and less, 3; not stated, 3. In searching for peculiarities among these cases, it may be stated that while there is nothing like uniform- ity in the ophthalmoscopic appearances, the preponder- ance of hyperaemic cases is to be noted. It is further notable that the degree of vascularity is very intense. This affects chiefly the capillary and venous circulation. See cases 12, 14, 15, 17, 18. The torpid condition of the cerebral nerve substance would appear to be re- flected in the intra-ocular circulation. 12. Man—Admitted December 21, 1870, aged 50, single, good habits. Dementia.

The cases of acute and sub-acute mania may be con- sidered together. Among the 20 are found a portion with hyperaemia of the nerve and retina, viz.: 14; and another part in which these tissues are either normal or anaemic, viz.: 6. Of the hyperaemic, the causes were: meningitis 3, ep- ilepsy 3, masturbation 1, over work 1, intemperance and syphilis 1, typhoid fever 1, phthisis 1, ill health 1, no cause given 3. The duration of the disease was comparatively brief, viz.: from two weeks to seven months; with one excep- tion, in whom it had lasted seven years and was caused by an injury of the skull, (case 49.) Of the cases not hyperaemic, the causes were: intem- perance 4, masturbation 1, ill health 1. Their duration was in all less than three months; one was only 10 days, (case 31.) It is true that the larger number of the cases show optic and retinal congestion, but in those which do not, the maniacal symptoms were severe. We would not assume that the vascularity of the nerve is always an index of the circulation in the hemi- spheres; but we may suggest that the variety found in the appearance of the optic nerve accords with the view that mania is the result of exhaustion of nerve force, as well as of over excitation. In the case of only ten days duration, the appearance of the nerve strongly suggests atrophy. The cases of meningitis all exhibit optic hyperaemia; and the case of old injury (49,) shows marked signs of chronic neuro-retinitis. 30. Man—Admitted February 28, 1871, aged 27. Masturbation.

The number of cases above described are too few to justify dogmatic generalizations. But one can not help being struck with the dissimilarity of the appearances in cases classified as belonging to the same category. The putting of a certain number of patients together, under one head, whose violent mental manifestations deserve the name of mania, is a convenience in certain respects; but no one pretends that this is a classifica- tion based on pathological distinctions. The actual state of the brain in these cases is widely unlike in dif- ferent individuals. Hence there is no wonder dis- crepancies in ophthalmoscojDic appearances. In classify- ing insanity, mental manifestations have been made the basis of distinction, because indeed we have been una- ble to determine the physical state of the brain, which was the real disease. The ophthalmoscope may help us during life to arrive at some knowledge on this vital subject. But the necessary limitations of its power of penetration must be borne in mind. First, that it 23 shows only one of the prolongations of the brain, which may not be involved in the brain lesion. Secondly, the magnifying power yet obtainable is too small to show the intimate texture of the optic nerve and retina. As in the brain, it is impossible often to see the true lesions without the higher power of the microscope; so for the optic nerve, we need much greater power than we yet have in the ophthalmoscope. But, despite these re- straints upon its capability, it shows us often important facts. For example, atrophy of the optic nerve not infre- quently precedes disorders of the brain and spinal cord; and sclerosis may be the pathological change at the foundation of all the lesions. Again, retinal hemor- rhage may be the precursor of cerebral hemorrhage. It is also true that serious lesion may exist in the optic nerve and retina without any damage to sight. In the case of the insane, it is important to question them closely as regards the degree of sight, and make them fulfill the proper test by test letters, such as those of Snellen. If practicable, the field of vision should be determined so as to discover defects in the peripheral part of the retina. Certainly the inspection of the optic nerve by the ophthalmoscope should never be neglected. It is hoped that opportunity may be afforded for con- tinuing the above investigations, and many more cases be added to to the above list. New York, December 15, 1871.
