“Vision is the art of seeing what is invisible to others”
It is not out of place so declared that imaging techniques have revolutionized ophthalmology. Imaging not just the retina, choroid, cornea, iris, angle, and the lens; techniques such as optical coherence tomography (OCT) have found newer applications with papers reporting its utility even in the evaluation of the lacrimal apparatus.
Focusing on the posterior segment, the entire management of vitreoretinal diseases has undergone a change since the advent of OCT. From macular holes to diabetic retinopathy; from age-related macular degeneration to cystoid macular edema: OCT has transformed our understanding of disease process.
We are currently in an exciting phase in ophthalmology – where not keeping up with technology is no longer an option. Personally as an academician and a clinician, I have witnessed this hi-tech revolution from close quarters, where concepts and hypotheses have been built and rebuilt around the newer diagnostic tools. Thirty years ago, the only imaging modality available was the ultrasound. At that time, to think that in a decade or so, each layer of the retina could be visualized in-vivo via a noninvasive, reproducible and reliable process - was unfathomable. And look where we are today! As Chhablani and Jayadev in their insightful editorial have eloquently; almost poetically, said that technology today allows us “to see beyond what our own eyes can see.”
More importantly, for many generations of practicing ophthalmologists, being relevant and clinically adept meant learning, unlearning, and re-learning while still in practice. In India, not all ophthalmic residency programs have access to advanced imaging facilities. While the occasional continuing medical education program may help; there's only that much that sporadic didactic lectures can do. Therefore, the need for a source of credible information on newer advances certainly exists. This is the lacuna that focused in-depth and comprehensive issues of the Indian Journal of Ophthalmology such as this special issue on “Retino-choroidal imaging” aims to address. By being the most widely read Ophthalmology Journal in India, the IJO is an authoritative source for current developments in ophthalmology. To disseminate this knowledge and to serve a platform for publishing the latest research in ophthalmology, is the vision of IJO.
This issue consists of exhaustive reviews and pertinent original articles on retinal and choroidal imaging. I congratulate the two invited editors, Jay Chhablani and Chaitra Jayadev for the commendable job of compiling the articles in this issue.
