In this study, using optical coherence tomography angiography (OCTA) we evaluated choriocapillaris perfusion in eyes with central serous chorioretinopathy (CSC) after excluding all possible artifacts caused by alterations of neurosensory retina or retinal pigment epithelium (RPE). We have included 22 unilateral acute CSC patients (18 males and four females, 41.8 ± 5.7 years) and 18 healthy subjects (13 males and five females, 40.9 ± 9.7 years). The number of flow voids per 1 mm2 of scan area and percentage of flow signal area was calculated based on choriocapillaris slab of 3 × 3 mm2 OCTA scans after excluding all possible artifacts caused by alterations of neurosensory retina or RPE. The percentage of flow signal area after the exclusion of neurosensory retina and RPE alterations in the eyes of healthy individuals was higher than in CSC eyes (p = 0.006) and fellow unaffected eyes of CSC patients (p = 0.02). The number of flow voids larger than 25,000 µm2 in eyes of healthy individuals was lower than in the CSC eyes (p = 0.0006). There were no statistically significant differences in study parameters between CSC eyes and fellow eyes of CSC patients (p > 0.05). The general decrease of choriocapillaris perfusion in both eyes of CSC patients exists independently of the presence of acute disease or asymptomatic structural RPE changes.

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.

Purpose: to compare informativity and accordance of indocyanine green angiography (ICGA) and optical coherence tomography angiography (OCT-A) data in visualization of neovascularization associated with chronic central serous chorioretinopathy. Patients andMethods. Twenty one eye of 21 patients (aged 51.0 ± 8.4 years old) with chronic central serous chorioretinopathy (CSR) and assumed choroidal neovascularisation (CNV) with «double layer» sign on optical coherence tomography scans were enrolled in this study. ICGA on Spectralis HRA+OCT, (Heidelberg Engeneering, Germany) and OCT-A on RTVue XR Avanti (Optovue, USA) were performed to evaluate CNV. The assessment of obtained pictures was examined by two experts.Results. Both diagnostic methods have shown similar results. CNV has been revealed in 11 of 21 eyes by ICGA imaging while OCT-A confirmed neovascularization in 13 eyes — with no statistical difference between methods (p = 0.74, χ2). CNV has not been diagnosed in 10 cases by ICGA and in 8 cases by OCT-A (p = 0.69). However, the consistency of the two methods in CNV evaluation while pairwise comparison of angiography data has been confirmed only in 8 eyes. The absence of CNV has been confirmed in 6 eyes — mostly in patients with CSR recurrence. One third of patients (7 of 21 eyes) have not shown consistence of two methods. The OCT-A visualization of CNV could be poor because of subretinal deposits and pigment-related signal blocking. In cases of diffuse retinal pigment epithelium atrophy the neovascular network cannot been seen on ICGA images while well visualized on OCT-A.Conclusion. The informativity of ICGA and OCT-A in visualization of neovascularization associated with chronic central serous chorioretinopathy is similar. For the best data interpretation the condition of neurosensory retina and pigment retinal epitheluium should be taken into account. OCT-A is more preferable in cases of diffuse epitheliopathy, while the neovascularization activity and leakage points is better seen on ICGA.

Abstract Purpose To report the observation of the choriocapillaris island (CCI) on optical coherence tomography angiography (OCTA) in eyes with active central serous chorioretinopathy (CSCR), and to investigate its associated clinical features. Design Retrospective observational study. Methods Patients diagnosed with active CSCR underwent OCTA imaging (Optovue Inc, Fremont, California, USA), and the software built-in en face choriocapillaris slab was examined to demonstrate CCI, defined as an area of detectable choriocapillaris flow surrounded by an area of undetectable or diminished flow. Electronic medical records (EMR) were reviewed for demographics, clinical data, other imaging modalities and any intervention, and these parameters were correlated with CCI findings. Results 25 eyes of 25 patients were recruited. CCI was detected in all examined eyes and was best elucidated on the en face choriocapillaris density maps. 24 eyes had focal retinal pigment epithelium (RPE) alterations overlying CCI. All 14 eyes with simultaneous fundus fluorescein angiography (FA) showed actively leaking point(s) well corresponding to the CCI location. Resolution of sub-retinal fluid in 4 eyes was associated with disappearance of CCI on follow-up OCTA scans. 1 eye showed complicating neovascularization 5 months after the initial presentation at the same location of the CCI. Conclusion We demonstrate the observation of the “choriocapillaris island” an OCTA finding in eyes with active CSCR underneath the area of neurosensory detachment. CCI may constitute an angiographic representation of the focal area of choriocapillaris structural and functional affection, with secondary RPE alteration jeopardizing its barrier function. Larger longitudinal studies are needed to further elucidate this finding.

Purpose: To describe abnormal dark (hyposignal) and white (hypersignal) lesions observed on optical coherence tomography angiography in central serous chorioretinopathy. Methods: Prospective, multicenter, and descriptive study including patients with active or quiescent central serous chorioretinopathy. All patients had undergone a complete ophthalmic examination. Results: Abnormal dark lesions were detected as “dark spots” and “dark areas” on optical coherence tomography angiography. A “dark spot” could correspond to six different abnormalities: pigment epithelium detachment, subretinal deposit, “Lucency” within surrounding subretinal fibrin, choroidal cavitation, choroidal excavation, and choroidal fluid. A “dark area” could be related to a serous retinal detachment or choriocapillary compression. Abnormal white lesions were also detected: A “white spot” could correspond with the leaking point on fluorescein angiography or with hyper-reflective dots; A “white filamentous pattern” at the Brüch’s membrane level corresponded to abnormal choroidal neovascular vessels. Conclusion: A semiology is described using optical coherence tomography angiography in central serous chorioretinopathy as abnormal dark and white lesions. Multimodal imaging is mandatory in addition to optical coherence tomography angiography to diagnose non-neovascular retinal and choroidal central serous chorioretinopathy lesions. However, optical coherence tomography angiography alone is helpful in detecting choroidal neovascular membrane in central serous chorioretinopathy.

Purpose: Combined hamartoma of the retina and retinal pigment epithelium is a rare benign tumor characterized by a variable combination of glial, vascular, and pigmented components. The purpose of our study was to analyze the features of combined hamartoma of the retina and retinal pigment epithelium on optical coherence tomography angiography. Methods: Small case series of two cases of combined hamartoma of the retina and retinal pigment epithelium with macular and optic nerve involvement, evaluated with multimodal imaging including optical coherence tomography, fluorescein angiography, and optical coherence tomography angiography. Results: On optical coherence tomography, combined hamartoma of the retina and retinal pigment epithelium is characterized by disruption of the inner neurosensory retina and a variable degree of involvement of the external retina. Optical coherence tomography angiography showed diffuse alterations of the retinal vessels of the superficial and deeper layers, extended to the peripapillary area. Vessel abnormalities included increased tortuosity and caliber of vessels, vascular traction, and vessel stretching within the lesion. Conclusion: Optical coherence tomography angiography allows in-depth multilayer analysis of tumor vascular network, highlighting the fine abnormalities of retinal vasculature characteristic of combined hamartoma of the retina and retinal pigment epithelium.

Purpose Handheld laser pointer thermal injury affects primarily the retinal pigment epithelium (RPE). However, so far no study has reported on the possible effects of laser pointers in the deeper layers, beneath the RPE. Here, we describe the spectral-domain optical coherence tomography angiography findings in the choriocapillaris of a patient with laser maculopathy. Methods A 13-year-old boy presented to our department with decreased vision in the left eye 12 hours after having stared at the beam of a laser pointer. Results Structural optical coherence tomography (OCT) showed 2 focal hyperreflective columns at the fovea extending from the RPE, involving all outer retinal layers, and terminating at the outer plexiform layer. The patient also underwent OCT angiography (OCT-A), which in the choriocapillary segmentation revealed 2 hypointense lesions in correspondence of the focal hyperreflectivities detected on structural OCT. We hypothesize that the OCT-A findings could represent a rarefaction of the choriocapillaris. However, the choriocapillary OCT-A findings could also represent artifacts due to the overlaying hyperreflective lesions. Conclusions It is known that the RPE is primarily damaged by the laser injury. Our findings suggest that the thermal injury could involve also the choriocapillaris, and thus not limited to the RPE. Multimodal imaging in laser maculopathy including OCT-A may lead to a better comprehension of the pathogenesis of laser retinal damages.

Introduction and purpose. Central serous chorioretinopathy - a disease that manifests itself serous detachment of the neurosensory retina and / or retinal pigment epithelium (RPE). Chronic course of pathological process may be complicated by the development of subretinal neovascularization, and is accompanied by a decrease in visual functions. Despite the large number of studies, there are no pathogenetically oriented and effective methods of treatment of central serous chorioretinopathy today, because there is no consensus on the causes of its origin. To evaluate the accuracy of the information content of chorioretinal blood flow changes in patients with central serous chorioretinopathy, to compare the degree of changes of RPE and hemodynamic disorders in different forms of the disease. Materials and Methods. The study involved 26 patients with central serous chorioretinopathy aged 35 to 54 years. To assess chorioretinal blood flow the optical coherence tomography (OCT) in retinal angiography mode was included in the volume of diagnostic examination. Results. It was demonstrated that the choroidal vessels and RPE are an original target in the realization of the pathological process in central serous chorioretinopathy. The changes in the pigment epithelium and the neurosensory retinal detachment, whose height ranged from 53.4 to 513.0 m (238.3 ± 80.4 - in acute and - 215.5 ± 129.9 - in chronic diseases) were revealed in all patients. In 45 % of cases of acute and 67 % in patients with a chronic form of disease the neurosensory retinal detachment combined with RPE detachment, preventing recovery of macular interface on a background of medical actions. Prolonged existence of ischemia and RPE detachment is accompanied by severe progressive degenerative changes in the retina as a whole, causing resistance to treatment. Conclusions. OCT in angiography mode in the diagnosis of various forms of chorioretinal central serous chorioretinopathy allows visualizing blood flow, evaluating the extent and nature of the structural changes of the retina taking into account hemodynamic disorders. The revealed changes of RPE and choroid, as classification and prognostic criteria of the disease, determine the effectiveness of treatment measures and prognosis of disease.

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.

Purpose. To present a case of acute idiopathic maculopathy (AIM) and illustrate primary choroidal perfusion defect using multimodal imaging. Case Description. We report a case of a 24-year-old man with a paracentral scotoma of the right eye and recent flu-like illness. The patient was found to have a unilateral ovoid-shaped, placoid lesion just inferior to the fovea. Multimodal imaging confirmed findings most consistent with a diagnosis of acute idiopathic maculopathy (AIM). Serologic studies confirmed a strongly positive immunoglobulin G (IgG) titer for coxsackievirus A. Spectral-domain optical coherence tomography angiography (SD-OCTA) showed bilateral areas of vascular reduction at the level of the choriocapillaris and choroid, sparing the retinal circulation. Conclusions and Importance. The changes in outer retina and retinal pigment epithelium, classically described in AIM, are likely secondary to choroidal hypoperfusion.
