,M! * June 18, 1930 Mr. Albert D. Cash, Doll.,' 0*Donnell and Cash* 704-707 Mercantile Library Bldg., Cincinnati, Ohio. Dear..Mr. Cashs,:...... ' .. . . . ' ' I have read over the information which you supplied me in the ^ S H H B h f c O a s e , and it seems to me that the conclusions to be arrived at are fairly clean cut, I do not see any reason for associating the accidental spillage of Ethyl Gasoline in this man's eyes, with the development a number of weeks later of a tuberculous iritis. I cannot but feel that the tuberculous condition is entirely independent and has no relationship what ever to his contact with gasoline. I arrive at these conclu sions for the following reasons. It is undoubtedly true that the spillage of Ethyl Gasoline into this man's eyes produced immediate pain, burning, redness, and general irritation of the external tissues of the eye. It is a matter of some doubt as to whether he had as bad a condition as commonly occurs from this cause, for if he had I would expect him to have applied to a physician at once. The usual course of injury to the eye resulting from such an irritation, is a considerable amount of burning and irritation, v/Ith congestion of the eyelids and the external tissues of the eye, the whole thing usually clearing up in from forty-eight hours to four days. If this man's eye injury had become progressively worse from the date of his ini tial injury from gasoline, he would undoubtedly not have waited until August to consult a physician* Ihen too, the internal tissues of the eye which are most involved In this man's case, are supplied by a different blood supply from that to the ex ternal portion of the eye* Therefore I cannot see any relation ship between irritation and congestion of the external tissues of the eye, and a deep seated infection Involving primarily the posterior and the deeper tissues of the eye. If I were asked the question as to whether I could say definitely that irrita tion of his ye could in any way.lnfluencethe oxisting tuber culous infection, I should have to reply that I could not cer tainly say. However, I should reply that it does not seem reasonable to me to assume a relationship between this not very severe injury, sod an acute tuberculous onset two months later* I do not believe, therefore, that there is any justification for regarding his accidental contact with gasoline as a con tributory factor to his Illness. ^ Very truly yours, RAK;EJ 'T-.-.'TTrT r.-M- 0010330 \. ->V. ...... j `r )
