Otto Heinrich Enoch Becker (1828-1890) was a German ophthalmologist.
Professor Becker is renowned for his publications in ophthalmology, particularly on lens pathology; and as an inspiring teacher, with many of his pupils later becoming leaders in the specialty.
His name is eponymous with Becker sign (1871) of retinal artery pulsation, and Becker test for astigmatism.

Becker sign (1871)
Prominent (spontaneous) pulsation of the retinal arteries.
Becker originally described this phenomenon in association with aortic insufficiency in 1871. Becker then proceeded to evaluate and document the phenomenon in 21 patients published in 1872. He turned his attention to the correlation of spontaneous retinal pulsation associated with exophthalmic goitre in 1873, and this association is the one most oft quoted .
…in allen Fällen von nicht mit anderen Klappen fehlern complicirter Insuffieienz der Aortenklappen die spontane Arterienpulsation beobachtet wird, und zwar um so deutlicher, je stärker gleichzeitig die Hypertrophie des linken Ventrikels entwickelt ist.
In all cases of incompetent insufficiency of the aortic valves, which are not accompanied by other valves, the spontaneous arterial pulsation is observed. The more pronounced the pulsations, the greater the degree of assoicated left ventricle hypertrophy. [Becker 1871]
Note: Becker attributes the original finding to Quicke who had previously described in relation to aortic regurgitation in 1868.
Lately I had an opportunity of observing the capillary pulse in still another place besides the finger nails, namely in the retina, and it was in one of the two cases of aortic insufficiency already mentioned, in a man who is still under my observationQuincke 1868
A test for astigmatism, made by means of a set of parallel lines in triplets placed in various meridians. The differences in definition, clearness or blackness indicates the degree of the defect and the meridian of the ocular astigmatism.
