564 THE COLLIERY GUARDIAN. March 13, 1914. a most important part in the causation of the disease, and there was no doubt but that injuries to the eye, or general injuries to other parts of the body, might be the determining factor in the onset of symptoms. He had noticed that nystagmus often came on during con- valescence from an accident, and he thought this was sometimes due not to the accident itself, but to the fact that the man when at work had been able to overcome the tendency to the disease. This opinion had been confirmed by the number of cases who broke down following resumption of work after the big strike of 1912 ; the six weeks’ enforced holiday had thrown them out of gear. In his own series there was a distinct connection between the onset of the disease and an accident in 94 cases. Treatment. . The treatment of miners’ nystagmus must be con- sidered under two headings. In the first place they must consider the treatment to be applied to the sufferer, and in the second place consider what preven- tive measures might be employed for the purpose of either diminishing the number of cases or eliminating the disease altogether. With regard to the personal treatment: this would depend entirely upon the severity of the case. In severe cases it was necessary for the man to give up work entirely and to have complete rest. If the examination of the eye showed any refractive error, this should be corrected by means of glasses, and in many cases after the patient had become accustomed to the altered conditions under which the muscles of the eye worked, he obtained some relief, at all events from such subjec- tive symptoms as headaches, giddiness, and nausea, while in some, cases these symptoms disappeared altogether. Ernest Clarke had pointed out that in neurasthenic cases the correction of small ocular defects was of the greatest importance, and he believed that in many cases the greatest amount of eye strain resulted from the smallest error of refraction. Neurasthenic symptoms must be treated in the ordi- nary way, and if the patient was suffering from neuras- thenia of a marked degree, Weir Mitchell treatment might be advised for a period of from four to six weeks. He did not think sufficient attention had been paid to the application of Weir Mitchell treatment in cases of nystagmus, and he believed that the association of miners’ nystagmus with neurasthenia had not been sufficiently recognised. He had pointed out in a previous lecture that in this country there were not sufficient facilities in the hospitals for the treatment of neurasthenia, especially by the Weir Mitchell treatment for working men who require such a course of treatment, and it was obvious that in their homes this treatment could not be carried out. As far as he knew, Weir Mitchell treatment was only properly carried out in England in nursing institutions, or in, perhaps, one or two hospitals in London devoted exclusively to the treatment of nervous diseases ; but in view of the fact that there were thousands of coalminers in the different colliery districts of this country incapacitated for work on account of miners’ nystagmus associated with neurasthenia, from an economic point of view it was most desirable that arrangements should be made in the hospital centres of colliery districts to provide the best possible treatment, in order to bring about speedy recovery. The best that could be done at the present time was generally to advise massages in the patients’ homes, although this could not be carried out unless the employer or insurance company was prepared to bear the burden of the expense, as the charges, speaking generally, were beyond the means of the average working man. In some cases, the patient might be sent to such a hospital as the Devonshire Hospital at Buxton, where a course of massage and baths would do a great deal of good for the sufferer. Convalescent cases derived great benefit from change of air, especially at bracing seaside resorts such as Blackpool or Rhyl. While the patient was “ suffering ” from any symptoms of this disease, work in the pit should be forbidden; but in mild cases, and in cases which were convalescent, a change of employment on the surface might result in great benefit, because his mind was occupied^ and he was not worrying about himself, as was very common in these cases: and, further, the exercise which ordinary manual work necessitated would do a great deal towards improving his nervous system. Some writers had stated that on recovery the miner might be allowed to work in the pit again, and this was a practice which was prevalent to a large extent in all mining districts ; but he thought to reduce the risk of recurrence it was advisable to place the man at such work that he was less liable to contract the disease than at his previous employment; for instance, a man who had worked as a holer might be employed as a roadman or a dataller, but if there were any recurrence after this return to different work, then the man should never be allowed to work in the pit again. During illness it was important that the man should lead a well-regulated life. He should keep good hours, and should be abstemious with regard to alcohol and tobacco. If there had been any previous tendency to excess in either of these habits, they should be entirely forbidden; and a patient suffering from nystagmus, whether he was incapacitated from work or not, should realise that the flickering of cinematograph performances had a detrimental effect upon his condition. With regard to medicinal treatment in cases where the nervous symptoms were pronounced, where the appetite was poor and there was sleeplessness, glycero phosphates and bromides might be given with good results, and among the other drugs which had been found to be successful are strychnine, quinine, and nux vomica. Romiee had advised the local application to the eye of eserine drops in a 3 per cent, solution three times a day. Atrophine had been tried without success. Operative treatment in the form of tenotomy had been recommended in cases of miners’ nystagmus ; but in every case, as far as he knew, in which an operation has been performed, disappointing results had ensued. Preventive Measures. Preventive measures might be considered under three headings : (1) Improvement in illumination of the mine ; (2) the extension of the use of coal-cutting machines; and (3) efficient ventilation of the workings. Going into some detail on this part of his subject, Dr. Shufflebotham said every man on his way to and from the face should be compelled to use a shade at the back of his lamp. He had often been told by men that they had had to sit down “ to let the lamps go by.” These shades should be provided by the management, but could be readily improvised by means of a piece of card- board or folded newspaper. It was the general opinion of working miners them- selves that bad air in the mine was the exciting cause of this disease ; whether this was so or not there was no doubt that bad air had a deleterious effect upon the general condition of the miner, and as they had seen that impaired general health was a predisposing cause of the onset of the disease, efficient ventilation in the mine was an important factor in its prevention. Mr. McMurray had suggested that all miners should be subjected to a systematic examination of the eyes, so that cases with any refractive error or with any other ocular defect could be prevented from commencing or continuing this kind of work. Undoubtedly, such a procedure would greatly diminish the incidence of nystagmic cases, but he (Dr. Shufflebotham) questioned whether the Miners’ Federation would consent to the institution of such an examination, as it would mean at the present time dismissal of thousands of miners who had worked in the pit all their lives, and who were continuing to do regular and efficient work, and further, it would mean the constant elimination at each periodic examination of numbers of workers who would be deprived of their means of livelihood, and with little chance of gaining employment elsewhere unless it were in the ranks of the casual labourer. If, however, a periodic examination were made, and the power of dismissal were prohibited in case of any ocular defects other than miners’ nystagmus being discovered, then it had been suggested that the workers be induced to wear spectacles when on the surface. In this way it is hoped that the correction of the refractive error will lessen the severity of the symptoms of this complaint. Incapacity for Work. Miners’ nystagmus was essentially an industrial disease. In spite of the various theories for the explana- tion of the symptoms, it could not be denied that the complaint was one which was a direct result of the conditions under which the miner works, and in view of the fact that it was a disease to which the Workmen’s Compensation Act applied, it was important to consider to what extent incapacity for work might result from this complaint. In the first place, he would point out that there was no necessary relation between the objective and sub- jective symptoms. Cases where the movements were very slight might be accompanied by distressing head- aches, attacks of giddiness, and other subjective symptoms, while well-marked oscillations sometimes might cause no trouble. It was difficult to tell whether a miner suffering from nystagmus was incapacitated from work or not. The objective symptoms by themselves might not cause any discomfort or incapacity for work ; but when associated with subjective symptoms they might have a case of total incapacity for work. A great deal, however, depended upon the subjective symptoms, for the existence and severity of which they were compelled to trust to the patient’s honesty. Meighan had classified the degrees of incapacity for work under three headings :— 1. Those slightly affected—men who suffer to a slight extent from the characteristic oscillations of the eyeballs—especially when they assume positions that strain the muscles of the eye. These men continue work and never become incapacited. He believes that 5 per cent, of all miners are affected slightly. 2. Those who suffer from the oscillations and feel giddy at times. These should be obliged to leave off the work in which they are engaged. They may require a rest for six months, but should not return to their old employment. 3. Those who suffer badly from oscillations, head- aches, giddiness, and other symptoms mentioned previously. These should give up underground work v entirely, and never return to it. Dr. Shufflebotham said complete incapacity for work might occur in those cases where the symptoms of nystagmus were absent or had disappeared, but where clonic spasm, plus other objective symptoms, were complained of. From the point of view of capacity for work, giddiness was the most troublesome subjective symptom and, if the attacks were at all frequent and came on without warning, the patient must be regarded as being totally incapable of work, and it was not safe to give him light work even on the surface. One-eyed men who suffered to any pronounced extent from the disease must be regarded as totally and permanently incapacitated. Again, cases in which neurasthenia was a prominent symptom must be regarded as of a severe type. Malingering. Amongst other observations under this heading, Dr. Shufflebotham said all observers were agreed that it was impossible to imitate the nystagmic movements of the eye, so that there could be no malingering with regard to this, the most prominent objective symptom. There was a difference of opinion as to whether clonic spasm of the eyelids could be simulated or not, but careful observation in any given case would easily detect malingering, as it was impossible for the patient to sustain, but for a minute or so, the twitching of the eyelids, and further, the voluntary movements which were induced by a malingerer were altogether different to a skilled observer from those which were seen in true cases of clonic spasm of the eyelids. Dr. Moody had pointed out that the movements in the latter case were quicker and finer, and if a miner attempted voluntarily to blink his eyelids quickly, he must bring other muscles into play apart from those which actually blink the eyes, and in Dr. Moody’s opinion the man would be easily found out. It should be clearly and widely known among all miners who might imagine that the simulation of this symptom was an easy matter, that they were entirely mistaken, and that if they tried it on before a skilled observer, they would be almost imme- diately found out. They might therefore, say that the two principal objective symptoms could not be simu- lated, and if a man was known to have attacks of giddiness and to fall about, to be suffering from night blindness, and, when tested by Cridland’s method, from a diminished field of vision, there could be no question as to the genineness of the case. The only difficulty might arise in mild cases where patients were capable of following some kind of employ- ment, such as light work on the surface, or in an occupation independent of coalmining. In many cases, as he had stated previously, miners with a definite oscillation of the eyeballs were able to do their work without any complaint for years in the absence of head- ache, dizziness and other subjective symptoms; but if a miner suffering from such a mild degree of the disease suddenly became aware of the presence of nystagmus, should he, for the purpose of claiming compensation under the Workmen’s Compensation Act, desire to make complaints of headache, giddiness, feelings of sickness and other symptoms for the existence of which they had to trust to his honesty, it would be most difficult to disprove the statements. The examining doctor would have to take into consideration the man’s record for work and his demeanour while under observa- tion, and assistance might be given by friends and neighbours who could testify one way or another as to the man’s general state of health. In dealing with such cases it was absolutely necessary to make a complete examination of the man, and a special examination of his eyes, such as he had described under the heading of “ Symptoms,” and he believed that a great deal of help would be obtained by paying special attention to the extent to which the field of vision is limited. There were undoubtedly many cases of miners who knew that they were suffering from miners’ nystagmus, but who went on working in spite of the complaint, and it was only when they gave up work, either on account of bad trade, or a strike, or because of some quarrel with an official or their employer, that they made a claim for compensation. During the coal strike of 1912, many such cases were recorded in different coal districts of this country. In all disputed cases, he would suggest that the medical referee under the Workmen’s Compensation Act not only relied upon his own examination and the reports submitted to him by the medical advisers of the work- men and the employers, but that he also took into consideration either verbal or written statements of workpeople or other persons who could speak as to the man’s previous history and his general condition of health. (To be continued.} Royal Commission on Railways.—Mr. Marshall Stevens, first manager of the Manchester Ship Canal and now chairman and managing director of the Trafford Park Estates, made some noteworthy suggestions before the Royal Commission on Railways in London on Friday. His three main proposals were as follow :—(1) That the railway companies must be compelled to charge separately for conveyance. (2 ) That the conveyance charge must be a reasonable one, having regard when compared with the present rates of carriage to the cost to the railway company of the other services and accommodation provided. (3.) That the Railway Commission should be reorganised, with full authority to take the initiative and to carry out each and every one of the recommendations of the Committee of 1872, as well as to revise the rates of conveyance and create through traffic arrangements upon broad lines* These reforms, ho said, were obtainable with very little alteration in the existing laws. Should it be thought that the railway companies would in any way be harshly treated by the recommendations being put into operation without some consideration, he would further recommend that — (a) the State should acquire the permanent way of the railways and convey traffic without providing any other services in regard to it; or (b) having taken a valuation of the permanent way of a railway, the State should guarantee the company interest upon that valuation in exchange for absolute freedom in the fixing of conveyance rates both for merchandise and passengers. Mr. Stevens declared that he was prejudiced against State ownership in the ordinary way, but it seemed absolutely impossible that, as regarded the working of general merchandise traffic, greater administrative waste could take place if the railways were owned by the State than was now taking place with the railway companies. The total amount of rates payable by the companies was .£5,000,000. Assuming that half of that was applicable to the railway lines, the .£2,500,000, capitalised upon a’25 years’ basis, would mean a contribution of 621 millions by the local authorities towards the purchase price. The Commission adjourned.
