Purpose. To investigate the fundus autofluorescence (FAF) spectrum of punctate inner choroidopathy (PIC).Methods. This is a retrospective observational case series of 27 consecutive patients with PIC admitted from October 2013 to March 2015, who underwent short-wavelength- (SW-) and near-infrared- (NIR-) FAF imaging, spectral domain optical coherence tomography (SD-OCT), fluorescein angiography (FA), and indocyanine green angiography (ICGA).Results. There were three primary findings on the FAF imaging of patients with PIC. First, active PIC lesions revealed hypoautofluorescent spots with hyperautofluorescent margin. After the lesions regressed, the hyperautoflurescent margin faded. Second, subclinical and most of the atrophic PIC lesions appeared to be hypoautofluorescent spots. But subclinical PIC lesions were more distinctive on NIR-FAF imaging than on SW-FAF imaging. Third, hypoautofluorescent spots of PIC lesions coexisted with hyperautofluorescent patches on SW-FAF imaging. These hyperautofluorescent patches were demonstrated to be multiple evanescent white dot syndrome (MEWDS) or acute zonal occult outer retinopathy (AZOOR) lesions by subsequent multimodal imaging and faded during follow-up examinations.Conclusion. FAF imaging helps in noninvasively tracking the evolution of PIC lesions and identifying the combined MEWDS or AZOOR lesions, complementary to SD-OCT and angiographic studies.

Purpose: To describe the findings of four patients (four eyes) with optic disc melanocytoma (ODM), using multimodal imaging. Methods: Retrospective case series. Results: On ocular ultrasonography ODMs appeared as hyperechogenic lesions with moderate-to-high internal reflectivity. On blue-light fundus autofluorescence, ODMs showed total hypoautofluorescence, while, on infrared reflectance images appeared as bright and well-marginated lesions. MultiColor composite images showed reddish-brown lesions with well-defined margins. Swept-source optical coherence tomography revealed elevated lesions covering the optic disc with an irregular hyperreflective surface, dishomogeneous internal structure with hyperreflective dots, and posterior shadowing. In all cases optical coherence tomography angiography detected intratumoral blood vessels which were not detectable with fluorescein angiography. Conclusion: Multimodal imaging in ODM might be useful both at presentation, increasing the diagnostic accuracy, and at follow-up, providing helpful details, that can help to rule out the possibility of malignant transformation and other ocular complications.

Purpose. To characterize vitelliform lesions (VLs) in adult-onset foveomacular vitelliform dystrophy (AOFVD) and acquired vitelliform (AVL) patients using multimodal image analysis.Methods. Retrospective study of twenty-eight eyes from nineteen patients diagnosed with AVL or AOFVD. They were evaluated by color fundus photographs, fundus autofluorescence (FAF), fluorescein angiography (FA), and spectral-domain optical coherence tomography (SD-OCT).Results. Bilateral VLs were associated with AOFVD(p=0.013). Regular and centered VLs were associated with AOFVD (p=0.004andp=0.016), whereas irregular and noncentered lesions were more frequent in AVL patients. Visual acuity, greatest linear dimension (GLD), lesion height (LH), and pseudohypopyon were similar between groups. Whereas median LH and GLD in AVL group diminished significantly during follow-up (p=0.009andp=0.001), AOFVD lesions tended to become larger and thicker.Conclusions. When consulting a patient presenting a VL with unknown age of onset, familial history, or previous retinal diseases, some aspects of multimodal imaging assessment may lead the ophthalmologist to a correct diagnosis.

Purpose. The recent use of “en-face” enhanced-depth imaging spectral-domain optical coherence tomography (EDI SD-OCT) helps distinguish the retinal layers involved in the physiopathology of multiple evanescent white dot syndrome (MEWDS).Methods. Four patients presenting with MEWDS underwent a comprehensive ocular examination including C-scan (“en-face”) EDI SD-OCT at the initial visit and during follow-up.Results. C-scans combined with the other multimodal imaging enabled the visualization of retinal damage. Acute lesions appeared as diffuse and focal disruptions occurring in the ellipsoid and interdigitation zones. The match between autofluorescence imaging, indocyanine green angiography, and “en-face” OCT helped identify the acute microstructural damages in the outer retina further than the choroid. Follow-up using “en-face” EDI-OCT revealed progressive and complete recovery of the central outer retinal layers.Conclusion. “En-face” EDI SD-OCT identified the site of initial damage in MEWDS as the photoreceptors and the interdigitation layers rather than the choroid. Moreover, “en-face” OCT is helpful in the follow-up of these lesions by being able to show the recovery of the outer retinal layers.

ObjectiveTo report the demographics and the clinical course of patients with multiple evanescent white dot syndrome (MEWDS) and to investigate for those factors which influence visual acuity (VA) recovery.MethodsThis is a retrospective single-centre observational study. Electronic medical records and retinal imaging of patients with a diagnosis of MEWDS with a minimum follow-up of 3 months were reviewed. Patients were categorised into three groups according to the VA at presentation and at the last visit: group 1 >0.48 logarithm of the minimum angle of resolution (LogMAR), group 2 ≤0.48 and ≥0.18 LogMAR and group 3 <0.18 LogMAR. All patients had non-invasive multimodal imaging including optical coherence tomography, near-infrared reflectance imaging and blue fundus autofluorescence at presentation and during follow-up.ResultsA total of 51 eyes from 51 patients (41 women, mean age 29.8±7.8 years) were included. Significantly more patients presented in the autumn (X2=8.69, p=0.034). The percentage of eyes recovering vision to 0.0 LogMAR or better was 80.3% (41/51). Worse presenting vision and young age at presentation were independent significant predictive variables for poorer final VA (p=0.002 and p=0.02, respectively). No imaging features were significantly predictive of complete versus incomplete recovery, but disc hyperfluorescence on fluorescein angiography was more common in those with incomplete recovery.ConclusionsAlthough the majority of cases have a benign prognosis, the clinical spectrum of MEWDS includes incomplete visual recovery. In our series, poor presenting VA and young age were associated with poor VA outcome. Further study is warranted to confirm these findings.

The purpose was to demonstrate the diagnostic and therapeutic feasibility of swept source-optical coherence tomography angiography (SS-OCTA) by picturing neovascular changes secondary to a rare white dot syndrome following long-term intravitreal ranibizumab (IVR). A 28-year-old Caucasian myopic female presented with visual loss in her right eye only. The clinical examination and multimodal imaging including spectral domain (SD)-OCT, blue-peak autofluorescence, fluorescein, and indocyanine green angiography (HRA Spectralis, Heidelberg Engineering; Heidelberg, Germany) as well as SS-OCTA (DRI Triton, Topcon; Tokyo, Japan) led to the diagnosis of idiopathic punctate inner choroidopathy with secondary subfoveal choroidal neovascularization (CNV). In addition to oral corticosteroids, a pro re nata regimen with IVR was initiated and guided by repeated SD-OCT and SS-OCTA. Six IVR were administered based on functional SS-OCTA en face scans illustrating vessel transformation and downsizing of the CNV area while SD-OCT B-scans were inconclusive as indirect signs of activity were absent throughout the follow-up period. SS-OCTA provided new possibilities for monitoring vessel development. IVR was managed based on vessel density as displayed by SS-OCTA.

Purpose. To determine whether fluorescein leakage within subretinal hemorrhage is definitely suggestive of choroidal neovascularization (CNV) by multimodal imaging including optical coherence tomography angiography (OCTA). Methods. Twenty-five consecutive highly myopic patients (25 eyes) with fluorescein leakage within subretinal hemorrhage detected within 1 month were prospectively included. All patients underwent OCTA and spectral-domain optical coherence tomography (SD-OCT). The OCTA and SD-OCT findings at the site of fluorescein leakage were analyzed. In cases of a doubtful diagnosis, indocyanine green angiography (ICGA) was also performed to differentiate myopic CNV from lacquer crack if necessary; all patients were followed up by SD-OCT and/or OCTA for at least 2 weeks. Results. In terms of the site of fluorescein leakage, OCTA revealed an abnormal vascular network in the outer retina and a choriocapillaris slab in 22 out of 25 eyes (88%), which were confirmed to be CNV. However, no high-flow signal was observed in 3 of 25 eyes (12%). In these 3 cases, SD-OCT showed a focal rupture of the retinal pigment epithelium-Bruch’s membrane-choriocapillaris (RPE-BM-CC) complex and a columnar hyperreflective signal of blood originating from defects with a volcanic geyser-like appearance, and no exudative signs were detected. Notably, all ruptures of the RPE-BM-CC complex were located exactly at lacquer crack sites. Moreover, with the absorption of subretinal hemorrhage, ruptures of the RPE-BM-CC complex spontaneously resolved without any intervention. Considering the multimodal imaging appearance and follow-up outcomes, these 3 eyes were eventually diagnosed as simple bleeding associated with lacquer cracks. Conclusions. Dye leakage within recent subretinal hemorrhage on FA could be caused by new-onset lacquer cracks in pathologic myopia. Multimodal imaging including OCTA is helpful to differentiate lacquer cracks from myopic CNV.

Chorioretinal Folds

Purpose To report 3 cases of ocular chorioretinal folds from different etiologies and their aspect with the new imaging technology of optical coherence tomography (OCT) angiography (OCT-A). Methods Baseline data, investigational process on etiology, and follow-up data of patients referred for chorioretinal folds to the Medical Retina & Imaging Unit of San Raffaele Hospital in the period January-March 2016 were collected. Multimodal imaging evaluation, comprehensive of infrared, fundus autofluorescence, multicolor, spectral-domain OCT, and OCT-A, was performed on all patients. Results Four eyes of 3 men, 65, 46, and 50 years of age, showed chorioretinal folds secondary to central serous chorioretinopathy, postoperative hypotony (after deep sclerectomy), and anisometropia with unilateral hyperopia, respectively. In all cases, OCT-A imaging showed a signal reduction in the choriocapillaris layer in correspondence of the folds. Due to this signal reduction, the en face reconstruction of choriocapillaris layer showed, in all cases, a peculiar tigroid aspect. The aspect of the folds at OCT-A remained unchanged during the 3-month follow-up in all patients. Conclusions Optical coherence tomography angiography shows a typical linear signal reduction in the choriocapillaris layer in correspondence of the fold with a tigroid pattern. We hypothesize this aspect could be explained by blood flow alteration at the choriocapillaris level in correspondence of the fold.

Purpose: To report a series of cases showing bilateral circumpapillary hyperpigmentation on routine fundus examination. Methods: In this observational case series, three patients showing bilateral circumpapillary hyperpigmentation on routine fundus examination were included. Multimodal retinal imaging was done for these cases. Results: Multimodal imaging of the lesion showed the hyper pigmentation to be confined to the choroid. The optical coherence tomography scans described the features through the hyperpigmented area, adjacent hypopigmented area and the normally pigmented area of the fundus as suggestive of choroidal hyper melanosis. Follow-up of these lesions over a period of 2–6 years showed no change in the vision or characteristics of the lesion. Conclusion: Bilateral circumpapillary hyperpigmentation needs to be considered as a differential for bilateral peripapillary pigmented lesions.

Abstract Background Multiple evanescent white dot syndrome (MEWDS) is a rare inflammatory eye condition affecting the outer retina as a consequence of choriocapillaris non perfusion. The pathophysiology of MEWDS will be discussed based clinical appraisal and on multimodal imaging appraisal. Methods Narrative review and perspective opinion. Results Literature review results helped us to put forward (1) the specific symptomatology (decreased/blurred vision, photopsia, subjective scotomas), (2) the ill-asserted character of clinical findings (foveal granularity, white dots in fundoscopy), (3) and the crucial importance of multimodal imaging with the diagnostic triad of ICGA hypofluorescent areas, BL-FAF hyperautofluorescent areas and loss/damage of IS/OS-ellipsoid zone on SD-OCT that characterise the disease and can practically help the clinician to diagnose MEWDS. A comprehensive alternative perspective of the disease was formulated. Conclusions The bulk of evidence that we are presenting in this review, thanks to new performing non-invasive and invasive imaging modalities, is sufficiently compelling to consider MEWDS as a primary choriocapillaritis/inflammatory choriocapillaropathy. Multimodal imaging allows the clinician to diagnose MEWDS with a high level of certainty and ensures a precise follow-up.

The purpose of the study was to analyze imaging findings in spectral domain en face optical coherence tomography (SD OCT) in patients with laser‐induced and solar maculopathies focusing on the possible regeneration of the ellipsoid zone. In a retrospective case series of 3 patients (4 eyes) with solar maculopathy and 2 patients (3 eyes) with laser‐induced maculopathy who underwent a comprehensive ocular examination, ellipsoid zone (EZ) was segmented from SD OCT data. Evaluation of EZ in en face OCT revealed a hyporeflective lesion surrounded by a hyperreflective border. The area of EZ alteration was measured manually in en face OCT. All patients showed partial EZ regeneration. Mean EZ alteration decreased from 0.12 mm2 (range: 0.05–0.32) at baseline to 0.07 mm2 (range: 0.01–0.22) at last follow‐up (p=0.018, mean follow‐up: 372 days; range: 115–592). Mean best visual acuity (BVA) improved from 20/36 at baseline to 20/30 (p=0.018). In conclusion, en face OCT imaging clearly delineated the area of EZ alteration in patients with laser‐induced and solar maculopathies. Follow-up showed significant reformation of the EZ as well as improvement of BVA.
