Author undertake to comply strictly with these time limits.

In symposia, the standard presentation time is 12 minutes followed by 3 minutes for discussion, unless the session organizers specify otherwise. For the benefit of a smooth session schedule and all participants, speakers are requested to adhere strictly to the allotted speaking time. A visual signal will indicate the end of the presentation.

All oral presentations must be submitted at the Central Media Check at least 2 hours prior to the corresponding session. Speakers of early morning sessions (8:30 – 9:45) must submit their presentation on the evening prior to the presentation. In case of early morning sessions on Thursday, speakers are required to upload their presentations online before the start of the congress. Presentations may be submitted on-site via USB stick or online prior to the congress. Online submission will be available via a designated link, which will be accessible from the beginning of September, approximately four weeks before the congress. All speakers will receive a separate email from M-Events Cross Media GmbH with access details and instructions regarding formats and codices. All speakers are requested to submit their presentations in MS PowerPoint format (16:9); presentations may include graphical, audio, and video content. To avoid display issues, all fonts should be embedded in the presentation. Speakers may review and make changes to their presentations at the Central Media Check. During the session, speakers will directly access their presentations at the speaker’s desk, and projection will be exclusively done via the conference system. Please note that the projection of slides or overhead transparencies is not possible and the use of personal laptops is not permitted.

Posters must be mounted in the poster exhibition area between 7:00 am and 8:00 am on the day of the respective session. Authors are responsible for removing their posters between 5:30 pm to 6:30 pm on the same day. Posters not removed by 6:30 pm will be removed and disposed of by the congress staff. If an author of a “Poster of the Day” is unable to retrieve the poster at the end of the congress, the congress staff will remove the poster and return it by mail to the author. Please inform the congress staff in advance if you are unable to collect your “Poster of the Day”.

Posters must comply with the following dimensions:

Width: 90 cm, height: 120 cm (upright format)

Materials for mounting posters and on-site assistance will be provided. Please include an email address on your poster so that participants may contact you with questions.

In addition, all posters may be uploaded to DOG on Demand. Authors will receive an upload link prior to the congress. An optional audio track may be added to the poster.

Poster sessions will take place from Thursday to Saturday immediately after the lunch break without parallel events (13:45 to 14:45 hrs.) in the Poster Exhibition, Hall 1. Each session will be held as a moderated small-group format in which the poster authors will present their findings in a 3 minute lecture, followed by a discussion led by two moderators.

Posters may be prepared in German or English.

To ensure that participants can focus on poster presentations without disturbance, headsets and receivers will be provided free of charge from staff at several locations in the poster lobby.

Poster authors are therefore requested to arrive at the poster exhibition in good time before the start of their session. All equipment must be returned immediately after session to the designated staff locations.

After each poster session, the moderators will select one outstanding poster as the “Poster of the Day” for that session. These selected posters will be transferred by the congress staff to a dedicated exhibition “Posters of the Day”. Unlike the remaining posters, “Posters of the Day” will be displayed for the entire duration of the congress.

Each day, a jury will select three exceptional posters from the Posters of the Day. The authors of the selected posters will receive the DOG Poster Award endowed with 500 Euros. The poster awards will be presented as follows:

Friday: Hall 1 during the first break (from 9:45 to 10:15)

Saturday: Award ceremony in Hall 1 (in 2026: from 9:45 to 11:30)

Sunday: Farewell ceremony in Hall 1 (from 13.30)

All posters, videos and presentations will be made available for viewing on DOG on Demand.

DOG on Demand archives congress contributions online and offers the opportunity to view missed presentations or revisit content at any time. The program includes all contributions whose authors have agreed to publication. Authors will receive an email from M-Events during the summer containing a link to upload their poster as a PDF. An optional audio track may be added. DOG on Demand is available free of charge to all congress participants.

The DOG thanks all authors who make their contributions available for publication on DOG on Demand.

The presenting author is required to attend the corresponding session. In exceptional circumstances, all co-authors may act as a substitute. In such cases, the DOG office must be informed accordingly in advance. Failure to display your poster or to attend the assigned poster session without prior approval may result in the DOG reserving the right to exclude submissions by the author from the next congress.

he DOG retains the copyright for accepted scientific contributions. As a result, authors of free papers, posters and videos are required to submit their manuscripts for review no later than January 31, 2026, to the respective editors of “Graefe’s Archive for Clinical and Experimental Ophthalmology”, “Die Ophthalmologie”, or “Klinische Monatsblätter für Augenheilkunde“. Authors who intend to publish their presentations in another scientific journal can make an informal request to the Recording Secretary of the DOG. This request should be directed to the DOG Office and must specify the name of the journal where the publication is planned.

Please send any questions regarding submission and technical matters via email to j.behrens@interplan.de. For on-site assistance, please feel free to approach the staff at the media submission desk or the hostesses at the conference counter at any time.
