Purpose: To report a case of quiescent choroidal neovascularization (CNV) associated with choroidal nevus using optical coherence tomography angiography (OCTA) during 5 years follow-up. Methods: Observational case report. Results: A 53-year old woman was referred our department with diagnosis of choroidal nevus. At 1 year follow-up, fundus autofluorescence revealed hyper/hypoautofluorescent area, infrared image showed hyperreflective area and enhanced depth imaging OCT presented a shallow pigment epithelium detachment without exudation or hemorrhage. Fluorescein angiography and indocyanine green angiography suspected the presence of CNV. Finally, OCTA confirmed a quiescent CNV with an increased flow area of the vascular lesion without any changes in best-corrected visual acuity. At 20 months and 5 years follow-up, the CNV remained quiescent showing no clinical activity on structural SD-OCT and no changes in CNV morphology on OCTA. Conclusion: This case shows the features of quiescent CNV secondary to choroidal nevus after long-term follow-up. OCTA represents a valid imaging technique that allows to identify the CNV and to monitor its progression over time.

Abstract Background. To describe changes in the retina/choroid in patients with Serpiginous Choroiditis (SC) by Optical Coherence Tomography Angiography (OCTA) in a multimodal imaging approach. Methods. Prospective, monocentric study of 24 eyes of 12 consenting patients diagnosed with SC, who underwent OCTA, which was analyzed and compared to other methods such as enhanced depth imaging-OCT, fluorescein angiography, indocyanine green angiography, and fundus autofluorescence. Results. The study group consisted of 9 patients with peripapillary SC, 1 macular SC, and 2 atypical cases. All eyes presented an inactive SC confirmed by standard imaging. OCTA demonstrated the lesions tridimensionally in great detail. There was no difference in the angioarchitecture among the 3 forms of SC. A loss of the choriocapillaris/retinal pigment epithelium left a “window-defect”, where the vessels of larger caliber of the choroid became recognizable and their appearance inverted (“white-on-black”). A relationship between the presence of segmentation errors (SE) in the slabs and low visual acuity was established with a one-way ANOVA. Conclusions. OCTA was able to non-invasively assess vascular lesions of the choroid/retina in patients with SC with a high degree of correlation to other diagnostic modalities. Consequent long-term assessments could lead to a better understanding of disease progression.

Introduction: To investigate choroidal thickness changes related to the clinical activity of inflammatory choroidal neovascularization in punctate inner choroidopathy/multifocal choroiditis as compared to myopic choroidal neovascularization. Materials and methods: Consecutive inflammatory choroidal neovascularization secondary to punctate inner choroidopathy/multifocal choroiditis, and myopic choroidal neovascularization were retrospectively reviewed. By means of enhanced-depth imaging optical coherence tomography, choroidal thickness was assessed at the same location before choroidal neovascularization development, at choroidal neovascularization onset (baseline), and after treatment. Results: Eleven eyes with inflammatory choroidal neovascularization and 11 eyes with myopic choroidal neovascularization were analyzed. Choroidal thickness beneath inflammatory choroidal neovascularization significantly increased at baseline and decreased after therapy (“Sponge sign”), reaching preclinical values. In particular, mean choroidal thickness under inflammatory choroidal neovascularization was 145 ± 85 µm at the preclinical stage, increased to 210 ± 103 µm at baseline (p = 0.006), and decreased to 136 ± 87 µm after treatment (p = 0.017). Conversely, no significant choroidal thickness changes were disclosed in myopic choroidal neovascularization eyes, under any location. Conclusion: Optical coherence tomography–based choroidal thickness evaluation may represent an additional useful tool to monitor inflammatory choroidal neovascularization activity. Moreover, choroidal thickness under choroidal neovascularizations could be used to discriminate the origin of choroidal neovascular membrane, either inflammatory or myopic, in doubtful cases and guide the therapeutic management.

Background: To evaluate long-term visual/anatomic outcome after anti-vascular endothelial growth factor (anti-VEGF) therapy in patients with fovea-involving fibrovascular pigment epithelium detachment (PED) presenting with choroidal neovascularization (CNV) on optical coherence tomography angiography (OCTA). Methods: Patients with fibrovascular PED or subretinal CNV confirmed by OCTA who were treated by a relaxed treat-and-extend regimen for 2 years were retrospectively reviewed. The best-corrected visual acuity (BCVA) and central subfield retinal thickness (CST) before and after anti-VEGF injection were analyzed. Furthermore, changes in photoreceptor layer (PRL) thickness and outer retinal bands in the fovea after injection were evaluated. Results: A total of 31 eyes with fibrovascular PED and 24 eyes with subretinal CNV were included. Following a relaxed treat-and-extend regimen with anti-VEGF agents, BCVA and CST were improved, and the PRL thickness was decreased significantly. There were no differences in BCVA, CST, changes in PRL thickness, or the status of outer retinal bands between the groups. However, the difference in the amount of decrease in PRL thickness between the two groups was increased at 2 years, and the slope tended to be steeper in the subretinal CNV group. Conclusions: Exudative age-related macular degeneration (AMD) with fibrovascular PED or subretinal CNV showed good visual/anatomic outcomes after anti-VEGF treatment, regardless of the CNV type. By 2 years, fibrovascular PED did not have an additional protective effect on the outer retina, compared with subretinal CNV over 2 years. Further follow-up study might be needed to conclude that fibrovascular PED has a protective effect on the surrounding photoreceptor area.

Purpose. To analyze optical coherence tomography angiography (OCTA) findings in eyes with central serous chorioretinopathy (CSC) and to compare them with those obtained with multimodal imaging.Methods. A series of consecutive patients diagnosed with CSC, underwent OCTA and multimodal imaging, including spectral domain OCT, fluorescein, and indocyanine green angiography. OCTA images were performed at three main depth intervals: automatically segmented outer retina, manually adjusted outer retina, and automatically segmented choriocapillaris.Results. Thirty-three eyes of 32 consecutive patients were analyzed. OCTA showed 3 main anomalies at the choriocapillaris: the presence of dark areas (19/33 eyes) which were frequently associated with serous retinal detachment, presence of dark spots (7/33 eyes) which were frequently associated with retinal pigment epithelium detachment, and presence of abnormal vessels (12/33 eyes) which were frequently, but not systematically, associated with choroidal neovascularization, as confirmed by multimodal imaging.Conclusions. OCTA revealed dark areas and dark spots, which were commonly observed. An abnormal choroidal pattern was also observed in one-third of cases, even when multimodal imaging did not evidence any choroidal neovascularization. Abnormal choroidal vessels should be interpreted with caution, and we could assume that this pathological choroidal vascular pattern observed in many CSC cases could be distinct from CNV.
