“…Imaging of the peripheral retina has become essential for the diagnosis, classification, and management of numerous diseases of the retina 7–16,18,19. Noncontact ultra-widefield fluorescein angiography with both the Optos ® Optomap ® and the Heidelberg Spectralis ® imaging systems permit excellent capture of the posterior pole as well as peripheral retinal pathology in a single, nonsteered shot.…”

“…Despite its ability to produce dynamic widefield fundus images, the Optos ® Optomap ® has several limitations. Specifically, its imaging of the far superior and inferior peripheral retina is less complete compared with its imaging of the temporal and nasal retina 18. Moreover, there is noteworthy distortion and decreased resolution of the far temporal and nasal peripheral retina.…”

PurposeTo compare ultra-widefield fluorescein angiography imaging using the Optos® Optomap® and the Heidelberg Spectralis® noncontact ultra-widefield module.MethodsFive patients (ten eyes) underwent ultra-widefield fluorescein angiography using the Optos® panoramic P200Tx imaging system and the noncontact ultra-widefield module in the Heidelberg Spectralis® HRA+OCT system. The images were obtained as a single, nonsteered shot centered on the macula. The area of imaged retina was outlined and quantified using Adobe® Photoshop® C5 software. The total area and area within each of four visualized quadrants was calculated and compared between the two imaging modalities. Three masked reviewers also evaluated each quadrant per eye (40 total quadrants) to determine which modality imaged the retinal vasculature most peripherally.ResultsOptos® imaging captured a total retinal area averaging 151,362 pixels, ranging from 116,998 to 205,833 pixels, while the area captured using the Heidelberg Spectralis® was 101,786 pixels, ranging from 73,424 to 116,319 (P = 0.0002). The average area per individual quadrant imaged by Optos® versus the Heidelberg Spectralis® superiorly was 32,373 vs 32,789 pixels, respectively (P = 0.91), inferiorly was 24,665 vs 26,117 pixels, respectively (P = 0.71), temporally was 47,948 vs 20,645 pixels, respectively (P = 0.0001), and nasally was 46,374 vs 22,234 pixels, respectively (P = 0.0001). The Heidelberg Spectralis® was able to image the superior and inferior retinal vasculature to a more distal point than was the Optos®, in nine of ten eyes (18 of 20 quadrants). The Optos® was able to image the nasal and temporal retinal vasculature to a more distal point than was the Heidelberg Spectralis®, in ten of ten eyes (20 of 20 quadrants).ConclusionThe ultra-widefield fluorescein angiography obtained with the Optos® and Heidelberg Spectralis® ultra-widefield imaging systems are both excellent modalities that provide views of the peripheral retina. On a single nonsteered image, the Optos® Optomap® covered a significantly larger total retinal surface area, with greater image variability, than did the Heidelberg Spectralis® ultra-widefield module. The Optos® captured an appreciably wider view of the retina temporally and nasally, albeit with peripheral distortion, while the ultra-widefield Heidelberg Spectralis® module was able to image the superior and inferior retinal vasculature more peripherally. The clinical significance of these findings as well as the area imaged on steered montaged images remains to be determined.

“…The Optos ® system has several important features, including the ability to acquire images through a native non-dilated pupil, a brief image acquisition time (250 ms), and the option of pseudocolor fundus photography [48]. However, use of the ellipsoid mirror in the Optos ® system distorts the peripheral retina, creating a topographic mismatch, and the view is limited superiorly and inferiorly [73]. The Optos ® system is also limited by lid and eyelash artifact, lack of real-time averaging, and poor contrast.…”

Clinical applications of fundus autofluorescence in retinal disease

Fundus autofluorescence (FAF) is a non-invasive retinal imaging modality used in clinical practice to provide a density map of lipofuscin, the predominant ocular fluorophore, in the retinal pigment epithelium. Multiple commercially available imaging systems, including the fundus camera, the confocal scanning laser ophthalmoscope, and the ultra-widefield imaging device, are available to the clinician. Each offers unique advantages for evaluating various retinal diseases. The clinical applications of FAF continue to expand. It is now an essential tool for evaluating age related macular degeneration, macular dystrophies, retinitis pigmentosa, white dot syndromes, retinal drug toxicities, and various other retinal disorders. FAF may detect abnormalities beyond those detected on funduscopic exam, fluorescein angiography, or optical coherence tomography, and can be used to elucidate disease pathogenesis, form genotype-phenotype correlations, diagnose and monitor disease, and evaluate novel therapies. Given its ease of use, non-invasive nature, and value in characterizing retinal disease, FAF enjoys increasing clinical relevance. This review summarizes common ocular fluorophores, imaging modalities, and FAF findings for a wide spectrum of retinal disorders.

“…Inferior eyelash artifact was present in 12 of 40 images (30%) in one study [ 19 ]. The Optos platform does not image the far superior and inferior peripheral retina as extensively as compared with its imaging of the temporal and nasal retina [ 14 ]. The Heidelberg Spectralis was shown to image the superior and inferior retinal vasculature more peripherally than the Optos Optomap in nine of ten eyes (18 of 20 quadrants); however, the Optos Optomap could image the nasal and temporal retinal vasculature more peripherally in ten of ten eyes (20 of 20 quadrants) [ 15 ].…”

“…A confocal scanning laser ophthalmoscope is combined with an ellipsoidal mirror to image the retinal periphery with one capture without the need for a contact lens, and most often, without mydriasis. Some of the limitations of the Optos platform are the distortion and decreased resolution of the far periphery as well as reduced superior and inferior fundus imaging in comparison to the temporal and nasal fundus [ 14 ]. More recently, Heidelberg (Heidelberg Engineering, Germany) released their noncontact lens system that attaches to the Heidelberg Spectralis and Retina Angiograph platforms to achieve ultra-widefield photography and angiography [ 15 ].…”

BackgroundUltra-widefield angiography is the latest technology in the evolution of fundus fluorescein angiography. With the ability to capture up to 200° of the fundus in a single image, far peripheral retinal pathology can be imaged. Generally, obtaining high-quality fundus fluorescein angiography in a child without sedation in the outpatient setting is exceedingly challenging. Therefore, there are advantages to imaging platforms that can capture the peripheral retina in young children without anesthesia. Often pediatric retinal diseases have pathology localized to the far periphery, which further validates the utility of ultra-widefield angiography. Ultra-widefield angiography has been successfully used without sedation for evaluation of children with various pediatric retinal diseases such as Coats disease, familial exudative vitreoretinopathy, and retinopathy of prematurity.ConclusionThis non-contact, non-mydriatic modality has been utilized in the evaluation of pediatric retinal diseases and demonstrated to have benefits over conventional fluorescein angiography techniques.
