Slit lamp atlas Videographic Imaging

This unique atlas with over 4000 images opens up new dimensions in slit lamp examination and documentation. In his "life's work", the author shows how the slit lamp can be used to depict almost the entire field of ophthalmology – from the eyelids and anterior segment to the fundus and portrayal of eye motility. This results in the first book in ophthalmology that covers the entire subject with just one device.

Traditional slit lamp examination techniques are combined with the innovative documentation of ophthalmic findings using videography. Access to these videos is provided in the book. They can be viewed via the More Media app.

Innovations:

• Purkinje reflexes functioning as "landmarks" for observing changes in the eye’s anterior segment–whether for the early detection of keratoconus or when assessing intraocular lenses
• The creation of fundus overviews, some of which extending to the periphery, using just the slit lamp and image processing programs
• Documentation of objects at a great distance by holding a minus lens in front of the objective lens of the slit lamp to make it less "short-sighted". This is useful to visualize squint or to take a picture of the whole face.

Inside the book:

• Methods section on technology
• Imaging with fundus-, minus- and without additional lenses
• Image documentation with patient-histories of up to 20 years
• 780 cases, including 460 follow-ups

Marcus-Matthias Gellrich, born in 1962, was one of the 1st prize winners of the German National Mathematics Competition at the end of his school-time in 1981. He studied medicine in Kiel (1982-1989) and Manchester, supported by the German National Scholarship Foundation, and earned his certification in ophthalmology at the University Eye Hospital in Freiburg. Since 1996 he has been a practising ophthalmologist in Kellinghusen in northern Germany.

Since 2006 Dr. Gellrich has been devoting intensive scientific effort to the slit lamp. It is his most fervent desire to encourage and witness the modernization of the slit lamp so that its potential can be fully exploited in today’s ophthalmology practices. To that end, he believes that a “sea change” must take place: From traditional biomicroscopy to a videographic approach that enables the slit lamp user to profit fully from recent technological breakthroughs such as video technology, digital image processing, and telemedicine.

This concept was presented in many lectures and films on national and international conferences (e.g. SOE and WOC) by Mr. Gellrich. It was also the main topic of his first book on the slit lamp, published in 2014.

The German Society of Ophthalmology (Deutsche Ophthalmologische Gesellschaft, DOG) awarded Dr. Gellrich the 1st video prize in 2007, 2015, 2017 and the Special video prize in 2011. He was also the first practising ophthalmologist to win the Hans Sautter Scientific Prize from the Association of the North German Ophthalmologists, which he received for a preliminary version of this comprehensive slit lamp atlas.
