His standing in the profession was largely the result of his textbooks of ophthalmology which were widely used in his home country and abroad.

His working career was spent at the Royal Infirmary of Edinburgh and when he retired from clinical practice in 1905 he became involved in medical and national politics.

His father was Walter Berry FRSE of Glenstriven in Argyll (d.1904), who was the Danish Consul General for Scotland.

He was resident house surgeon in Moorfields Eye Hospital in London in 1878-79 and at this very early stage of his career he was an enthusiastic supporter of the formation of the Ophthalmological Society of the United Kingdom which was established in 1880.

In Copenhagen he attended the clinic of his uncle Professor Edmund Hansen Grut and studied under Jannik Bjerrum.

[3] His reputation as an ophthalmologist extended throughout Europe and the USA largely as a result of the success of Diseases of the Eye- a Practical Treatise for Students of Ophthalmology which became a widely read textbook .

Its success was because it was widely considered to be a comprehensive account of the state of knowledge of the speciality and also because of the many original observations which it contained.

In addition he published two monographs which were widely acclaimed and used, Subjective symptoms in Eye Disease (1886)[8] and The Elements of Ophthalmoscope diagnosis (1891).

[10] Berry published an early description of the rare facial dysostosis condition which was initially called Berry-Treacher Collins syndrome.

[12] In the First World War he served as a territorial officer in the Royal Army Medical Corps with the rank of major.

[1] In 1886, at an early stage in his career, Berry was awarded the prestigious Middlemore prize by the British Medical Association (BMA).

[3] He is buried in Dean Cemetery in western Edinburgh The grave lies on the concealed southern terrace.
