What is the Image Library?
The Image Library consists of over 32,000 multimodal images covering the spectrum of vitreoretinal disorders. Also included are annotated bibliographies for most disorders covering over 6,000 major publications and studies.
We love gorgeous pictures so virtually all images are of publication quality. More important than a pretty picture, however, is what that picture teaches us about a disease. Many of the Retina Rocks images are therefore meant to tell a story or convey a “teaching moment,” exploring the multiple ways a disease changes over time, responds to treatment or presents with a cool or unique finding.
What’s included in the Image Library?
Researching a topic of interest may include looking for cool pictures, learning about the various ways a disease can present or progress, or wanting to review the literature. Retina Rocks is unique in that it provides for all of this. Within each folder you’ll find an annotated bibliography of key references, obtained from our Reference Library, and a variety of multimodal images including fundus photos, ultra-wide field images, fundus autofluorescence, fluorescein and OCT angiography, spectral-domain and swept-source OCT and videos. Most content is presented in a case format which usually includes grouped multimodal images often followed over time.
How is the Image Library organized?
The collection is organized alphabetically by topic into about 375 folders. Major topics are subdivided as needed to make it easier to search for specific findings. For example, age-related macular degeneration (AMD) is subdivided into 32 folders and diabetic retinopathy into 17. The collection’s index is the best way to find what you’re looking for. It is at the top of collection or can be downloaded here.
Below the collection’s index are “Fake-outs,” “Recent files,” and “Unknowns”. Fake-outs contain cases where exam or imaging shows findings that can mislead the clinician to the wrong diagnosis. Recent files contains files for the prior 3 months. Please let us know if you can solve any of the Unknowns!
Many cases are illustrative for more than one topic. For example, the ‘bone spicules’ typical for retinitis pigmentosa (RP) is caused by loss of photoreceptor inhibition, which allows for RPE cells to migrate into the retina along retinal capillaries. This phenotype is seen in other causes of photoreceptor loss or damage, including blunt trauma and chronic retinal detachment. So when browsing the RP folder, we’ve also included cases of pseudo-RP. We’ve done the same type of thing throughout the collection, which is why you’ll often find seemingly unrelated images when looking up a specific disorder. We believe this greatly enhances the learning process and helps with differential diagnoses.
Why can’t I search by file name or key word?
Unfortunately, the Google Drive Search function will not work due to limitations in the underlying Drive functionality. Finding what you’re looking for should still be easy due to how the collection is organized. Just be sure to download the collection’s index which will give you a bird’s eye view of all topics.
How can I browse the Image Library?
Files can be viewed as either a list or grid. Images can be sorted as desired into either ascending or descending order.
The file naming convention is as follows:
The list view is best for helping you know all the information about a particular case. Files are named so all like disorders and cases sort with each other. Within a disorder, individual cases will sort chronologically as well. We’ve included many examples of patients followed over time, some for over several decades, with descriptions of how things are changing. Instead of viewing a single image at a single point in time, this will allow you to view the full temporal course of a disease or finding.
The grid view, on the other hand, is best when you just want to browse through images. However, this view doesn’t generally allow you to understand what’s going on in any given case.
The file names are cut off in the grid view but can still be seen by hovering over the file label. Changing the zoom level of your browser will let you see more or fewer images at a time.
To view a file, simply double-click on it in either the list or grid view. Files can be downloaded as shown here. Individuals are free to view and download images for their personal use, including for patient education and personal lectures. However, publication of any of the collection’s images is not allowed without our express written permission.
