Serial Slit Lamp Photography – Taking Control

Angela Chappell

Ophthalmology Dept, Flinders Medical Centre, Bedford Park, Australia

Purpose: Serial slit lamp photography is the process of producing images of the same eye at different moments in time. The interval between images may range from minutes to years. The aim is to impart information about change in the eye over time to the clinician in support of patient care. To best illustrate change occurring in the eye, images need to be consistent and comparable. There are a number of variables which can adversely affect image repeatability which the photographer needs to be aware of. In this presentation some cases with serial imaging will be examined in order to highlight the various parameters, discuss how to control these and show that the longer the period of time spanned by the imaging, the greater the scope for image variability.

Ophthalmic Photography in The Rotterdam Eye Hospital

Gerard W. de Graaf

The Rotterdam Eye Hospital, Rotterdam, The Netherlands

Purpose: The Rotterdam Eye Hospital was founded in 1874. Ophthalmic photography has a long tradition and forms the backbone for treatment and scientific studies. In the presentation we will look back and forward and explain how the department is running on a daily basis.

Methods: Historic analysis on the hospital and research on people and equipment in the past. Evaluation and explanation on the current situation.

Results: General overview on a modern diagnostic department which is ready for the future, despite difficulties moneywise.

Conclusion: The Rotterdam Eye Hospital is an independent eye hospital. Despite the fact there have been several attempts to connect it to Erasmus University Hospital in Rotterdam and despite the fact it has a much smaller financial basis, it is still possible to have such a small but highly specialised hospital with a similar highly specialised photographic department.

Ophthalmic Photography in the Netherlands: Past and Present

Jeroen Grimbergen

Ijsselstein, The Netherlands

Purpose: The first attempts to produce photographs of the human fundus were done in the second half of the end of the 19th century, shortly after the introduction of the ophthalmoscope. Although the centre of development of fundus cameras lay in Germany, considerable improvements were made in the Netherlands by professor Salomonson, who built his camera in 1917. It is one example of contributions of Dutch scientists to ophthalmic photography. In the early 60’s Fundus Fluoresceine Angiography was introduced in the Netherlands. Many ophthalmic photographers were trained by Albert Aandekerk, whose work meant a great contribution to the quality of imaging. Since the introduction of digital imaging techniques the tasks of ophthalmic photographers have changed. In general hospitals, ophthalmic imaging is carried out by optometrists and ophthalmic technicians. Only at University Centres and the Rotterdam Eye Hospital, Ophthalmic photographers are employed. The OFN (Ophthalmic Photographers Society) was founded in 1997. It is a platform for those who are interested in ophthalmic imaging. Its annual symposium in Rotterdam is always well attended.

On Reflection: Retro-illumination in Veterinary Ophthalmic Photography

John Mould

Eye Veterinary Clinic, Leominster, Herefordshire, United Kingdom

Purpose: To illustrate the value of the tapetal reflex in ophthalmic photography of the dog and cat.

Methods: Most dog and cat eyes contain a tapetum, a layer of cells situated in the inner choroid immediately outside the choriocapillaris. The tapetum is brightly coloured in shades of green, yellow or orange and its function is to reflect light back onto the photoreceptors to maximise the stimulus in dim light. The “red reflex” is important in clinical examination and ophthalmic photography in man. In most dogs and cats the equivalent of the red reflex is therefore the tapetal reflex which is not red but the colour of the tapetum i.e shades of yellow etc.
