Ophthalmology Landscape: Ancient Roots to Technological Breakthroughs

The study and treatment of eye disorders date back to ancient times, with historical records such as the Ebers Papyrus from ancient Egypt referencing eye diseases and it can also be traced back to ancient Babylon with a reference to the eyes made in the Code of Hammurabi (2250 BC). The field of ophthalmology has evolved considerably since, with significant advancements in diagnosis and treatment methods.

In the pre-Hippocratic period that followed, the anatomical concept of the eye was primarily hypothetical. It is believed that Alcmaeon of Croton, a well-known philosopher-physician of that time (540–500 BC), was the first to study and describe the human eye. Alcmaeon of Croton’s theories were developed further in the Hippocratic Corpus, a collection of over 60 early ancient Greek medical writings by Hippocrates (460-375 BC).


Sushruta, a celebrated physician, and surgeon who performed medical surgeries in ancient India during the fifth century BC, is widely regarded as the father of Indian ophthalmology. His contribution the Sushruta Samhita, the concluding chapters of which are known as the Uttara Tantra, include comprehensive explanations of 76 eye conditions (Nayana-Budbada), similar to trichiasis (Pakshma-kopa), uveitis (Adhi-mantha), cataract (Kacha), and glaucoma (Gambhirika), among others.

Furthermore, the 14th century marked the beginning of the Renaissance, a fervent period of “rebirth” in science, culture, and politics for Europe. It was during this time that the physicians specialising in ophthalmology came to be known as “oculists”, a term adapted from the Latin word oculus meaning ‘eye’.

Further groundbreaking advancements in ophthalmology emerged with the invention of the slit lamp, created in 1911 by German optician Carl Zeiss (1816-1888) and Swedish ophthalmologist Allvar Gullstrand (1862–1930) using the Nernst electric bulb. This revolutionary discovery enabled great significance to practical ophthalmologists as it enabled a magnified, illuminated view of the inside of the eye with a slit of light and made making more accurate diagnosis and treatment of various eye conditions possible.

Because of the efforts of pioneers, most notably Sir Harold Ridley (1906-2001) and Charles Kelman (1930-2004), the 20th century also emerged as the dawn of a golden period for cataract surgery.

In recent years, ophthalmology has experienced rapid technological advancements, enhanced the field’s capabilities and contributed to superior ocular care for patients worldwide. The evolution of Artificial Intelligence (AI) in medicine has witnessed significant milestones spanning from the first industrial robot arm to natural language processors and AI-based decision-making systems. However, the period between 1970 and 2000, known as the “AI winter,” witnessed a lot of skepticism and limited progress due to cost and other prevalent challenges. In recent years, AI has undergone a renaissance in ophthalmology, driven by major advances in computational power, learning algorithms, and the availability of massive datasets.
