Penn State Eye Center, Hershey, Pennsylvania, USA

Purpose: A review of the cSLO confocal tonal shift and its effect on different pathologies.
Methods: The Heidelberg Spectralis confocal scanning laser ophthalmoscope (cSLO) is a commonly used diagnostic imaging device that uses monochromatic laser illumination to image the eye. The cSLO utilizes a focused laser to scan the subject and then captures the reflected light after it passes through a confocal pinhole. The pinhole suppresses out-of-focus light from reaching the image detector resulting in high-contrast, finely detailed images. The cSLO is most light efficient (brightest) at the plane of focus.

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.

Purpose: To describe a variety useful imaging modalities for identifying Ebola-specific retinal abnormalities and demonstrate the advantage of employing spectral domain optical coherence tomography longitudinally for follow-up.

Angela Dale

Purpose: The British Ophthalmological Surveillance Unit published a report in 2017 that highlighted up to 22 patients per month may be losing vision by such delays experienced in hospital eye services (HES) in the UK. This study reports on the development of a virtual clinic, run by ophthalmic technicians, to manage a cohort of patients with diabetic retinopathy (DR) who were being monitored under the HES whose follow up appointments had been delayed.

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.

Jeroen Grimbergen

Ijsselstein, The Netherlands

Purpose: Not often B-scan Ultrasonography procedures are performed by non-physicians. But with the right practice, it can be done by optometrists or ophthalmic technicians. As one of them, I would like to share my experiences.

Methods: A short history of USG and examination techniques will be presented.
Conclusion: A B-scan image can be a important diagnostic tool in case of intraocular pathology such as tumors and in case of eyes that are impossible to examine by funduscopy. Some examples will be shown.

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.

Gary Miller

Geisinger Eye Institute, Danville, Pennsylvania, USA

Purpose: To present a case illustrating the causal connection between ocular findings in a pediatric patient and a rare continental disorder.

Results: Ophthalmic photographers often document ocular findings with non ocular origins. This case will highlight the case of a rare congenital disorder and it’s embryonic connection to ocular findings in a pediatric patient.

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.

Ethan Priel, FOPS

MOR Ophthalmology Dept., MOR Institute, Bnei Brak, Israel

Purpose: To assess the contribution of Optical Coherent Topography Angiography (OCTA) when evaluating microvasculature morphology surrounding the central macula in eyes with idiopathic macular telangiectasis type 2 (MacTel 2). Results were compared to findings from fluorescein angiography (FA), fundus autofluorescence (FAF), confocal blue reflectance (CBR) and spectral-domain OCT (SDOCT).

Ethan Priel, FOPS

MOR Ophthalmology Dept., MOR Institute, Bnei Brak, Israel

Purpose: To present Infra-Red Auto Fluorescence (IRAF) – which highlights unique findings in the early, unremarkable stages of Central Serous Chorioretinopathy (CSCR) – and to assess the possible contribution of Optical Coherent Topography Angiography (OCTA) in locating Choroidal Neo-Vascular membranes during the acute, often chronic, stages of the disease. Results were compared to findings from Fluorescein Angiography (FA), Indocyanine Green Angiography (ICGA), Fundus Autofluorescence (FAF), Infra Red Imaging (IR), MultiColor imaging (MC), Confocal Blue Reflectance (CBR) and spectral-domain OCT (SD-OCT).

Olivia Rainey, OCT-C, COA

Retina Specialists of Michigan, Grand Rapids, Michigan, USA

Purpose: To describe UWFP for assessment and monitoring of posterior pediatric pathology. UWFP can improve clinical assessment and potentially decrease the burden of examinations under anesthesia for pediatric patients with conditions such as retinopathy of prematurity, retinoblastoma, traumatic injury, hereditary disease, retinal detachment, among others.

Frank P.J. Smolders

University Medical Center Groningen UMCG, Gytsjerk, Fryslân, The Netherlands

Purpose: Informative, unconventional results in anterior ophthalmic photography.
Results: To have your anterior segment photograph series in good order for eye research and registration, it takes skills and clarity. One picture is, most of the time, not sufficient. Series of well illuminated slit lamp photographs do have a great value on follow-up research.

Conclusion: I’d like to present a useful standard way of anterior segment photography, followed by unusual cases using unconventional light beams.

Frank P.J. Smolders

University Medical Center Groningen UMCG, Groningen, The Netherlands

Purpose: This presentation will show some useful try-outs, which is actually very basic knowledge, to inspire and motivate the it-does-makes-sense photographer!
Methods: Also in ophthalmic imaging, box enhancement and using several color filters can be serious tools to use for delicate details in -not only- retina but also in anterior photography.

Results: Better pigmentation, vein and other indications.

Conclusion: Better pigmentation, vein and other indications.
