## Career

Having decided to specialise in ophthalmology at an early stage, he gained experience in that speciality by visiting clinics in London, Utrecht and Copenhagen. He became a Fellow of the Royal College of Surgeons of Edinburgh in 1899.
Also in 1899 he was appointed clinical assistant in ophthalmology at the Royal Infirmary of Edinburgh (RIE) under Sir George Berry from whom he learned the fundamentals of clinical perimetry. Berry maintained links with the ophthalmic surgeons in Copenhagen who had developed the technique and Sinclair was able to develop this further. In 1905 he was made Assistant Ophthalmic Surgeon in the RIE and Ophthalmic Surgeon to Leith Hospital and to the Royal Hospital for Sick Children in Edinburgh.
In the First World War he served in the Royal Army Medical Corps with the Salonika Expeditionary Force. From 1922 to 1932 he was Surgeon in charge of wards at the RIE.
His main contributions to ophthalmology were the introduction of quantitative perimetry, a method for measuring the visual fields. he described the use of this technique in the diagnosis of glaucoma. Sinclair introduced the operation of intracapsular extraction of the lens for cataract. His series of 257 cases published in 1932 was regarded as showing the best results published to that time.
After retiring he became chairman of the W H Ross Foundation for the Study of the Prevention of Blindness. It was on Sinclair's suggestion the fund was established. Among the advances which the Foundation made was the successful treatment of infections of the cornea in coal miners which greatly reduced the resulting blindness in that occupational group.
