ICTER contributes to a global handbook of visual optics

Researchers from ICTER are among the authors of the latest volume of the Handbook of Visual Optics, edited by Prof. Pablo Artal – one of the most important contemporary references on vision technology and ophthalmic diagnostics.

The new volume, “Handbook of Visual Optics. Volume Two: Instrumentation and Vision Correction”, published by Routledge, is a comprehensive, expert resource focused on modern ophthalmic instrumentation and methods of vision correction. It covers, among others, optical coherence tomography (OCT), adaptive optics systems, and advanced techniques for imaging and analyzing vision.

Handbook of Visual Optics. Volume Two: Instrumentation and Vision Correction

ICTER researchers co-authored two chapters in this publication.

Two key chapters

One of the chapters focuses on two-photon vision. It was co-authored by Prof. Maciej Wojtkowski and Dr. Katarzyna Komar, together with Silvestre Manzanera and Pablo Artal. The chapter explains how, under very intense infrared light, the retina can “detect” a signal that would normally be invisible – by simultaneously absorbing two photons instead of one. This phenomenon makes it possible to probe the limits of human vision and develop new methods for precise retinal stimulation and functional diagnostics.

The second chapter focuses on imaging of the anterior segment of the eye using OCT. It was co-authored by Dr. hab. Karol Karnowski, Dr. Ireneusz Grulkowski, and Bernhard Baumann. The authors show how modern OCT systems enable cross-sectional, microscopic imaging of ocular structures without contact and in real time. The chapter reviews current technological solutions – from conventional setups to more advanced high-resolution, high-speed systems – and discusses their applications in diagnosing eye diseases and planning treatment.

What is the Handbook of Visual Optics?

ICTER’s presence in such a publication goes far beyond symbolic recognition. The Handbook of Visual Optics serves as a key reference for researchers and engineers working on new methods of ocular imaging and vision correction. It features solutions that actively shape the future of ophthalmology and medical technology. The significance is further underscored by the fact that Prof. Pablo Artal is a member of ICTER’s International Scientific Committee, highlighting the center’s strong and lasting ties to the global research community.
