Dear friends, colleagues, and strabismus enthusiasts,

it is my great pleasure to invite you all to attend the 44th Annual Congress of the European Strabismological Association held in Istanbul, Türkiye from 12th - 14th June 2025. After the spectacular ESA Meeting in Izmir 2004 and ISA Meeting in Istanbul 2010 we return to Turkiye to enjoy Turkish hospitality.

The Scientific Programme will be organised jointly with AAPOS – as we did very successfully 2017 in Porto – and the Turkish Ophthalmological Society. A big thank you to Huban Atilla, Şule Ziylan and Seyhan Özkan who will be the local organizers.

We will have our traditional 2½ day ESA program including our usual favourite sessions such as Round Table, Orthoptic Symposium, Early Morning Surgery Course, and our ever-popular John Lee rapid fire Poster session and “A Case I have learnt from…”. The 7th pre-meeting Strabismus workshop “What you always wanted to ask about strabismus ..." invites especially beginners in strabismology and people who start to come to ESA meetings. The Toulouse workshop 2024 was very interactive, instructive, and good fun for presenters and participants as well.

Last and by no means least, we invite you to submit abstracts of your own work. Presenting and discussing your research as talk or poster will form a major part of the programme.

For the first time there will be an extra day of Paediatric Ophthalmology sessions organized by AAPOS and the Turkish society. Because ESA by-laws clearly state that we promote strabismology in all its aspects - but not paediatric ophthalmology in general - there must be a separate registration for this extra day on Wednesday 11th June. I strongly recommend joining.

On Wednesday we will also host the EBO Subspeciality exam Strabismus and Paediatric Ophthalmologie together with the EPOS (European Paediatric Ophthalmological Society). More informations can be found at .www.ebo-online.org

Transport links to Istanbul are excellent. So again, as in Toulouse we expect participants from countries all over the world.

As ESA President it is my immense pleasure to meet you all at the congress in the vibrant city of Istanbul.

Oliver Ehrt, MD
President of European Strabismological Association


Dearest Colleagues and Future Friends,

On behalf of the entire American Association of Pediatric Ophthalmology and Strabismus, I am excited to help co’host the combined ESA/AAPOS/TOA meeting in the wonderful city of Istanbul, Turkey.

For many of us, this will be the first opportunity we have had to attend an international meeting since the pandemic ended, and I personally am very excited to see Istanbul and Turkey for the first time.

We expect to have many attendees from all over the world. The wonderful advantage of an international symposium and meeting like this is to share the diverse views, and learn from the best experts in strabismus treatment and binocular vision development.

One of the highlights will be the Knapp lecture, which is sponsored by AAPOS in memory of Dr Phillip Knapp, a famous strabismologist from the USA. More details about the named lecturer and the lecture title are forthcoming. AAPOS will also have a symposium that will feature topics of pediatric ophthalmology, including pediatric retina, pediatric cornea, and pediatric glaucoma featuring experts from the USA. This can’t be missed!!

I can guarantee that we will have a high-standard scientific program, that will not only allow us to have exciting scientific discussions, but also rekindle old friendships, and establish new ones.

I promise that your attendance will be rewarded with an increase in knowledge and skills, and memories of a wonderful city, and making new friendships.

Sean P. Donahue, MD
President of American Association for Pediatric Ophthalmology and Strabismus
