An Arabic manuscript, dated 1200CE, titled Anatomy of the Eye, authored by al-Mutadibih.

Ophthalmology was one of the foremost branches in medieval Islamic medicine. The oculist or kahhal (کحال), a somewhat despised professional in Galen’s time, was an honored member of the medical profession by the Abbasid period, occupying a unique place in royal households. Medieval Islamic scientists (unlike their classical predecessors) considered it normal to combine theory and practice, including the crafting of precise instruments, and therefore found it natural to combine the study of the eye with the practical application of that knowledge.[1] The specialized instruments used in their operations ran into scores. Innovations such as the “injection syringe”, a hollow needle, invented by Ammar ibn Ali of Mosul, which was used for the extraction by suction of soft cataracts, were quite common.

Muslim physicians described such conditions as pannus, glaucoma (described as ‘headache of the pupil’), phlyctenulae, and operations on the conjunctiva. They were the first to use the words 'retina' and 'cataract'.

Education and history

To become a practitioner, there was no one fixed method or path of training. There was even no formal specialization in the different branches of medicine, as might be expected. But some students did eventually approximate to a specialist by acquiring proficiency in the treatment of certain diseases or in the use of certain drugs.

Nevertheless it was standard and necessary to learn and understand the works and legacy of predecessors. Among those one can mention, The alteration of the eye by Yuhanna ibn Masawayh, whose work can be considered the earliest work on Ophthalmology, followed by Hunain ibn Ishaq, known in the west as Johannitius, for his work The ten treatises of the eye.

Cataract extraction

The next major landmark text on ophthalmology was the Choice of Eye Diseases written in Egypt by the Iraqi Ammar bin Ali Al Mawsili [1] who attempted the earliest extraction of cataracts using suction. He invented a hollow metallic syringe, which he applied through the sclerotic and successfully extracted the cataracts through suction. He wrote the following on his invention:

"Then I constructed the hollow needle, but I did not operate with it on anybody at all, before I came to Tiberias. There came a man for an operation who told me: Do as you like with me, only I cannot lie on my back. Then I operated on him with the hollow needle and extracted the cataract; and he saw immediately and did not need to lie, but slept as he liked. Only I bandaged his eye for seven days. With this needle nobody preceded me. I have done many operations with it in Egypt."[2]

In his Coliget, [6]

Ibn al-Nafis wrote a large textbook on ophthalmology called The Polished Book on Experimental Ophthalmology. The book is divided into two sections: "On the Theory of Ophthalmology" and "Simple and Compunded Ophthalmic Drugs".[7]Other significant works in medieval Islamic ophthalmology include RhazesContinens, Ali ibn Isa al-Kahhal’s Notebook of the Oculists, and the ethnic Assyrian Christian Jibrail Bukhtishu’s Medicine of the Eye, among numerous others.

Ottoman Empire

In the Ottoman Empire, and well into the Republic of Turkey of the 20th century, a class of ambulatory eye surgeons, popularly known as the ‘kırlangıç oğlanları’ (‘sons of the swallow’) operated on cataract using special knives. From contemporary sources can be glimpsed that the reputation of these “blinding frauds” was far from spotless.[8]
