Both these cases shew the necessity of inquiring particularly into the causes of diseases of the eyes, as well as of other parts of the body; for by barely attending to the symptoms, the disease will not be removed, tho’ the symptoms be alleviated. Bleeding, and moderate evacuations, would certainly have, at first, decreased the tension and pain, and assuaged the inflammation; but both topical applications, and internal medicines, were properly to be adapted, and a suitable diet regulated. Not to mention the absurd and impertinent abuse of empirics, what benefit could accrue, in both these cases, from unctuous, laxative, or emollient applications, from drastic and mercurial purges? Tho’ such applications might be well intended, to take off the tension and inflammation; yet, as the distension of the blood-vessels only increased gradually, as the globe of the eye was enlarged; so whatever application relaxed the coats of the eye, must infallibly stretch out the vessels yet farther, and cause a greater pain and inflammation; which drastic and mercurial purges would also increase. The only method then to be pursued in such bad cases would be at first to endeavour to remove the fullness of the blood, and make use of such topical remedies as would contract without irritation. If the cause remains, as the whooping cough in Susannah Earle’s case, no amendment of the eye can be expected, while the patient’s blood-vessels are continually strained by frequent coughing. This illness therefore should be attended to, and removed as soon as possible. But should the eye be so enlarged, as to protrude itself out of the orbit, there seems no other way to lessen the bulk of the eye, than by making a puncture with a proper instrument, to let out the aqueous humour; and then apply such agglutinant and contracting _collyria_, as may reduce the distended coats and vessels to their former size. This operation should be performed before the humours are vitiated, the sight lost, the vessels in a state of suppuration, and the coats of the eye too far extended; for at that time nothing less than extirpation can be of use. Professor Nuck, in his _Tractatus de Ductibus Oculorum Aquosis_, p. 120, _& seq._ relates the success he had in curing a young man by five repeated punctures, and a strict observance in a proper use of all the non-naturals. I am, with the greatest regard and esteem, Dear Sir, Your most affectionate Brother, and very humble Servant, D. P. Layard.
