Abstract
There is a lack of knowledge about the effect of flavanols-rich dark chocolate intake on the anatomy and functionality of retinal vessels. The aim of this study prospective, randomized, blind, crossover clinical trial (ClinicalTrials.gov Identifier: NCT05227248, 07/02/2022) was to evaluate the effect of dark-chocolate intake on the functionality and anatomy of the retinal vessels in healthy subjects using dynamic vessel analyzer (DVA) and optical coherence tomography angiography (OCT-A). Twenty eyes of 20 healthy subjects (mean age, 24.4 ± 1.6 years; 12 females) were enrolled. Participants were randomized to consume 20 g of dark chocolate or 7.5 g of milk chocolate. Visual function, DVA and OCT-A parameters were evaluated before chocolate consumption and two hours later. One week later, the same participants were tested before and after consuming the opposite chocolate. Using OCT-A, no differences were disclosed in terms of perfusion density changes after dark-chocolate and milk-chocolate intake analyzing all chorioretinal plexuses (p > 0.09 in all analyses). Using DVA, a significant increase in the arterial dilation percentage after flicker stimulation was disclosed comparing baseline (2.750 ± 2.054%) with values after the dark chocolate intake (4.145 ± 3.055%, p = 0.016). This difference was not disclosed after the milk chocolate intake (p = 0.465). We disclosed that a reasonable amount of flavanols-rich chocolate in healthy subjects has benefic functional short-term effects in retinal vessels measured with DVA. This suggests a potential role of dark chocolate intake on retinal vessels. Further studies with long-term follow-up are warranted to show if the chronic assumption of dark chocolate could play a favorable role in the prevention of retinal diseases.

Abstract
This case report describes a new type of perifoveal retinal vascular abnormality (RVA) incidentally discovered during a posterior vitreous detachment (PVD) investigation. A 65-year-old woman with sudden central visual loss displayed a unilateral focal telangiectatic venule in the perifoveal area. Multimodal imaging documented the vascular abnormality and associated retinal changes. Despite symptom resolution, the RVA persisted. This case represents a unique presentation of perifoveal RVA, likely an atypical form of macular telangiectasia. The sequential imaging documentation during a process of PVD with central bouquet traction provides insights into the underlying mechanisms in addition to diagnosing and monitoring perifoveal RVAs.

Abstract
BACKGROUND To describe the occurrence of nonexudative intraretinal fluid (IRF) in intermediate age-related macular degeneration. METHODS A retrospective study was designed to include consecutive cases with intermediate age-related macular degeneration associated with IRF. A multimodal imaging approach was used to confirm diagnosis of IRF in intermediate age-related macular degeneration. Multimodal imaging included color fundus photograph, fundus autofluorescence, fluorescein angiography, indocyanine green angiography, optical coherence tomography, and optical coherence tomography angiography. RESULTS Ten eyes of 10 patients (2 male and 8 female patients, ages 68-80 years) showing IRF in intermediate age-related macular degeneration were included in the study. The mean best-corrected visual acuity was 20/40 Snellen equivalent. Multimodal imaging including fluorescein angiography/indocyanine green angiography and optical coherence tomography demonstrated the absence of macular neovascularization in all cases; optical coherence tomography-angiography did not detect any abnormal flow signal associated with IRF. Seven of 10 patients developed IRF in correspondence of pigment epithelium detachment. Three of 10 patients presented IRF in correspondence of an area of nascent geographic atrophy. CONCLUSION Nonexudative intraretinal fluid in intermediate age-related macular degeneration is a novel, distinctive feature that is characterized by the presence of IRF with no evidence of macular neovascular lesions. The authors described different phenotypes of IRF in intermediate age-related macular degeneration. The definite diagnosis of this condition requires further studies with thorough application of multimodal imaging.

Abstract
PURPOSE To report a case of exudative perifoveal exudative vascular anomalous complex (ePVAC) in a Brazilian healthy patient that underwent a complete resolution after aflibercept intravitreal injections. CASE DESCRIPTION A 41-year-old healthy Brazilian man complained of acute central vision loss in his right eye (RE). Fundus examination showed a perifoveal hemorrhagic aneurysmal lesion, accompanied by several hard exudates in RE. On fluorescein angiography, these abnormalities showed a progressive hyperfluorescence with surrounding leakage. Optical coherence tomography (OCT) revealed a deep, perifoveal hyporeflective cystic space with a hyperreflective wall and hyperreflective material inside of fibrin-like aspect. Around this aneurism, intraretinal hyporeflective spaces suggestive of exudation were detected. Nor pathological flow signal, or telangiectatic dilations were evidenced on OCT-angiography. Therefore, a diagnosis of exudative ePVAC in RE was hypothesized. After an initial observation, the patient underwent three monthly aflibercept intravitreal injections (0.05 ml/2 mg), with a significative anatomical and functional improvement after two weeks from first dose. On last follow-up at five months from baseline, patient experienced no evidence of new exudation and a stable visual acuity. DISCUSSION Placental growth factor (PlGF) may impact on pericytes' dropout, and thus on ePVAC development. In contrast to the other anti-VEGF drugs, aflibercept is the only molecule contrasting PlGF. Therefore, aflibercept would act on ePVAC not as an anti-VEGF drug, but rather as an anti-PlGF one. CONCLUSION This report encouraged the use of aflibercept as a therapeutic option for ePVAC. Further studies are required to confirm our result and the impact of PlGF on ePVAC pathogenesis.

Abstract
PURPOSE Perifoveal exudative vascular anomalous complex is an uncommon retinal lesion of idiopathic origin characteristically described as an isolated, aneurysmal lesion of the perifoveal region. We report an unusual presentation of an exudative vascular anomalous complex-like lesion affecting the peripapillary area. CASE DESCRIPTION A 69-year-old diabetic woman presented with blurred vision in her left eye for two months. Fundus examination of the left eye showed a small, reddish-orange lesion just supratemporal to the optic disc with perifoveal hard exudates and retinal thickening. Fundus fluorescein angiography demonstrated a peripapillary hyperfluorescent lesion with minimal leakage. Ocular coherence tomography showed an oval structure extending throughout the outer and inner plexiform and nuclear layers with a hyper-reflective wall accompanied by subfoveal and intraretinal fluid suggestive of an eVAC-like lesion in the peripapillary area. Intravitreal anti-vascular endothelial growth factor injection was given, and the lesion persisted even three weeks after the injection. Later, focal laser photocoagulation of the aneurysmal lesion was done. At 6 weeks follow-up, a complete resolution of the aneurysmal lesion with a marked decrease in retinal edema and an improvement of the visual acuity was observed. CONCLUSION Exudative intraretinal aneurysmal lesions can occur in areas other than perifoveal area. OCT is an useful investigation for knowing their characteristics and the response to treatment. These aneurysmal lesions irrespective of their location can be called by the name eVAC-like or more aptly retinal capillary macro aneurysms (RCM).

Abstract
PURPOSE To report the use of intravitreal triamcinolone to treat macular edema associated with isolated perifoveal exudative vascular anomalous complex (PVAC) and resembling lesion (PVAC-RL). METHODS In this case series, three diabetic patients (3 eyes) with PVAC-RLs and one healthy patient (1 eye) with PVAC lesion associated with cystic spaces underwent three intravitreal injections of aflibercept before switching to one intravitreal triamcinolone injection in each patient. RESULTS Macular edema improved from 297.5 ± 8.10 μm, at baseline, to 269.2 ± 8.89 μm, after triamcinolone; whereas visual acuity improved from 20/38 to 20/26 (ETDRS). CONCLUSION PVAC and PVAC-RL are rare and often misdiagnosed lesions that may be associated with decreased vision. Our outcomes suggest that intravitreal injection of triamcinolone may be an effective and affordable treatment for PVAC and PVAC-RL with intraretinal fluid.

Abstract
Purpose To analyze the multimodal imaging characteristics of intraretinal macroaneurysms. Patients and Methods Intraretinal aneurysms larger than 150 μm in diameter on fluorescein angiography were termed as intraretinal macroaneurysm and grouped as primary and secondary according to the absence or presence of any coexisting posterior segment diseases. Results A total of 20 intraretinal macroaneurysms were observed in 18 eyes of 18 patients. Mean age of the cohort was 65.44 ± 9.14 years (Range; 49-82 years). Mean diameters of intraretinal macroaneurysms were 238.20 ± 61.12 μm (Range; 163.00-292.50 μm) and 242.72 ± 49.58 μm (Range; 168.00-328.00 μm) on fluorescein angiography and optical coherence tomography, respectively. Primary group had 10 eyes with 11 intraretinal macroaneurysms, whereas eight eyes had nine intraretinal macroaneurysms in the secondary group. Three of the eight eyes (37.5%) had diabetic retinopathy, four (50%), retinal vein occlusion, and one (12.5%), posterior uveitis in the secondary group. No statistically significant differences were found between the two groups in terms of age, sex, presence of intraretinal or subretinal fluid, the mean age, the mean central macular thickness, the mean distance of intraretinal macroaneurysms from the fovea, the mean diameter of intraretinal macroaneurysms measured on fluorescein angiography, and the mean diameter of intraretinal macroaneurysms measured on optical coherence tomography. Presence of intraretinal fluid was significantly more frequent than the presence of subretinal fluid in all eyes (p = 0.004). Conclusion Intraretinal macroaneurysms are diagnosed more and more with the utilization of multimodal imaging techniques. We propose a simple classification system in order to help achieving a standardized terminology and ensure consistent understanding. The classification can be simplified as primary or secondary intraretinal macroaneurysm according to the absence or presence of the associated posterior segment disorders.

Abstract
PURPOSE To report a case of exudative perifoveal vascular anomalous complex treated with a 532-nm subthreshold micropulse laser unresponsive to intravitreal injections. METHODS A case report. RESULTS A 65-year-old woman presented with blurred vision in the left eye for 1 month. An isolated perifoveal aneurysm surrounded by retinal hemorrhages and hard exudates was revealed in fundus examination, and optical coherent tomography showed a round lesion with a hyperreflective wall, subretinal fluid, and an intraretinal cyst. She was diagnosed with exudative perifoveal vascular anomalous complex and received four intravitreal injections. However, her best-corrected visual acuity decreased, and an aneurysmal lesion with macular edema persisted for approximately 6 months. Three sessions of 532-nm subthreshold micropulse laser therapy around the aneurysm were applied because the intravitreal injection treatment was ineffective. Since the last session, macular edema disappeared, the involuted lesion remained substantially stable without recurrence, and her best-corrected visual acuity improved without visual field defect. CONCLUSION To our knowledge, this is the first report of a successful subthreshold micropulse laser treatment for an exudative perifoveal vascular anomalous complex lesion, and it could be a safe and effective method for the patient unresponsive to intravitreal injections.

Abstract
PURPOSE To investigate the association of nascent geographic atrophy (GA) preceding the development of exudative type 3 macular neovascularization (MNV) in patients with age-related macular degeneration (AMD). DESIGN Retrospective longitudinal study. PARTICIPANTS Patients with AMD diagnosed with treatment-naive exudative type 3 MNV in 1 or both eyes were evaluated. Inclusion criteria included serial tracked structural OCT examinations for ≥ 2 years before the detection of exudative type 3 MNV. METHODS Clinical characteristics and retinal imaging, including structural OCT at baseline and at each follow-up examination, were analyzed. Eyes showing the presence of nascent GA during the follow-up were selected for analysis of prevalence, and clinical characteristics at the site of subsequent type 3 MNV development. MAIN OUTCOME MEASURES Description of the prevalence and clinical characteristics of nascent GA at the site of subsequent type 3 MNV development. RESULTS Overall, 97 eyes affected by type 3 MNV meeting inclusion criteria were analyzed. Of 97 eyes (71 patients), 22 eyes of 21 patients (mean age 82 ± 9 years) showed nascent GA preceding exudative type 3 MNV. The observed prevalence of nascent GA preceding exudative type 3 MNV was 22.7% (95% confidence interval, 14.4%-31.0%). Exudative type 3 MNV developed a mean of 9 ± 6 months after detection of nascent GA. The presence of reticular pseudodrusen in the study eye did not significantly influence the timing of exudative type 3 MNV development after the observation of nascent GA (P > 0.1 in all analyses). Reduced best-corrected visual acuity was recorded at the exudative type 3 stage in comparison with the nascent GA stage (P = 0.003). CONCLUSIONS As nascent GA may precede the development of exudative type 3 MNV, the detection of nascent GA in eyes with AMD may warrant closer surveillance to identify early exudative type 3 MNV warranting treatment.

Histology of type 3 macular neovascularization and microvascular anomalies in treated age-related macular degeneration: a case study. OPHTHALMOLOGY SCIENCE 2023; 3:100280. [PMID: 36970117 PMCID: PMC10033755 DOI: 10.1016/j.xops.2023.100280] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 01/16/2023] [Accepted: 01/30/2023] [Indexed: 02/11/2023]
Abstract
Purpose To investigate intraretinal neovascularization and microvascular anomalies by correlating in vivo multimodal imaging with corresponding ex vivo histology in a single patient. Design A case study comprising clinical imaging from a community-based practice, and histologic analysis at a university-based research laboratory (clinicopathologic correlation). Participants A White woman in her 90s treated with numerous intravitreal anti-VEGF injections for bilateral type 3 macular neovascularization (MNV) secondary to age-related macular degeneration (AMD). Methods Clinical imaging comprised serial infrared reflectance, eye-tracked spectral-domain OCT, OCT angiography, and fluorescein angiography. Eye tracking, applied to the 2 preserved donor eyes, enabled the correlation of clinical imaging signatures with high-resolution histology and transmission electron microscopy. Main Outcome Measures Histologic/ultrastructural descriptions and diameters of vessels seen in clinical imaging. Results Six vascular lesions were histologically confirmed (type 3 MNV, n = 3; deep retinal age-related microvascular anomalies [DRAMAs], n = 3). Pyramidal (n = 2) or tangled (n = 1) morphologies of type 3 MNV originated at the deep capillary plexus (DCP) and extended posteriorly to approach without penetrating persistent basal laminar deposit. They did not enter the subretinal pigment epithelium (RPE)-basal laminar space or cross the Bruch membrane. Choroidal contributions were not found. The neovascular complexes included pericytes and nonfenestrated endothelial cells, within a collagenous sheath covered by dysmorphic RPE cells. Deep retinal age-related microvascular anomaly lesions extended posteriorly from the DCP into the Henle fiber and the outer nuclear layers without evidence of atrophy, exudation, or anti-VEGF responsiveness. Two DRAMAs lacked collagenous sheaths. External and internal diameters of type 3 MNV and DRAMA vessels were larger than comparison vessels in the index eyes and in aged normal and intermediate AMD eyes. Conclusions Type 3 MNV vessels reflect specializations of source capillaries and persist during anti-VEGF therapy. The collagenous sheath of type 3 MNV lesions may provide structural stabilization. If so, vascular characteristics may be useful in disease monitoring in addition to fluid and flow signal detection. Further investigation with longitudinal imaging before exudation onset will help determine if DRAMAs are part of the type 3 MNV progression sequence.

Abstract
Perifoveal anomalous exudative vascular complex (PEVAC) was first described in 2011. Since then, individual clinical cases and a couple of case series have been published, and their characteristics have been studied in multi-modal images. To date, there is no consensus on its treatment. Initially, it was thought that PEVACs could be left to spontaneous evolution because they presented a slow progression. But it has been shown that the growth of the lesion covers a spectrum from non-exudative lesions to PEVAC with vision impairment over time. We present an updated bibliographic review of this pathology. We explain the changes in the diagnostic criteria that have been undergone. And we focus the discussion on selective treatment with focal laser, which has shown an excellent anatomical response and visual improvement or stabilization in the cases described and in our series of three patients systematically treated with focal laser.

Abstract
PURPOSE To characterize and distinguish non-neovascular deep retinal age-related microvascular anomalies (DRAMA) from type 3 macular neovascularization (MNV) using volume rendering of OCT and OCT angiography (OCTA). DESIGN Retrospective, consecutive case series. SUBJECTS Consecutive patients with age-related macular degeneration (AMD) exhibiting de novo non-neovascular abnormalities within the deep vascular plexus (DCP), as detected using high-resolution (High-Res) spectral-domain (SD) and swept-source (SS) OCT or OCTA. Patients with retinal vascular alterations attributable to other disease entities were excluded. METHODS Complete ophthalmic examination and multimodal imaging, including confocal fundus photography (CFP), SD-OCT, High-Res SD-OCT and OCTA, and volume-averaged SS-OCTA. The volume renderings of High-Res OCTA and averaged SS-OCTA were used to analyze capillary abnormalities and inflow or outflow connectivity pathways. MAIN OUTCOME MEASURES The primary outcomes were the characteristics of capillary abnormalities (number, size, shape, reflectivity, and location) and inflow or outflow connectivity pathways. The secondary outcomes were nearby changes in CFP and structural OCT (hyperreflective foci [HRF], outer retinal atrophy, and retinal pigment epithelium [RPE] atrophy). RESULTS From 8 eyes of 8 patients, 2 subtypes of DRAMA were identified: small-diameter perifoveal capillary dilations with hyperreflective walls within the inner nuclear layer (type 1, n = 4) and vascular outpouchings, typically multiple, extending posteriorly into the Henle fiber layer, with reflectivity similar to adjacent normal retinal capillaries (type 2, n = 10). Four eyes had both subtypes of DRAMA. The 3-dimensional visualization of OCTA data demonstrated DRAMA corresponding to the dilations of DCP capillaries without direct inflow or outflow connections to the superficial plexus. Fundus photographs showed circular red dots in 3 eyes, all corresponding to type 1 DRAMA. In all the cases, DRAMA colocalized with HRF. No lesions were found anterior to the areas of the RPE or outer retina atrophy. Asymptomatic intraretinal exudation varied through a follow-up duration of up to 6 years, with no lesions progressing to type 3 MNV. CONCLUSIONS In eyes with non-neovascular AMD, DRAMA include 2 types of capillary dilations occurring without the remodeling of the surrounding vascular network. Deep retinal age-related microvascular anomalies can resemble microvascular changes due to other causes and can masquerade as type 3 MNV. Mild intraretinal exudation can vary during follow-up, without progression to type 3 MNV.

Abstract
AIM To characterise macular neovascularisation (MNV) developing in eyes affected by geographic atrophy (GA). METHODS In this multicentric longitudinal study involving three retina referral centres, patients previously affected by GA who developed an active MNV were included. Patients were investigated using structural optical coherence tomography (OCT), fundus autofluorescence, OCT-angiography and dye angiographies. Patients were treated with ProReNata antivascular endothelial growth factor (VEGF) injections and were revaluated after treatment. RESULTS Among 512 patients previously diagnosed with GA, 40 eyes of 40 patients (mean age 80.8±7.9 years, mean GA area 8.73±7.39 mm2) presented with treatment-naïve exudative MNV (accounting for an estimated prevalence of 7.81%; 5.49 to 10.13, 95% CIs) and thus were included in the analysis. 67.5% of MNVs were classified as type 2 MNV, 25% as type 1, 2.5% as type 3 and 5% as mixed phenotype. In 92.5% of cases, active MNV in GA showed subretinal hyperreflective material with or without evidence of subretinal/intraretinal hyporeflective exudation. During a mean follow-up of 28±25 months, patients were treated with 6.6±6.3 anti-VEGF injections, with 2.9±1.4 injections in the first year of treatment. No patient developed GA enlargement in the area of MNV. CONCLUSIONS MNVs in GA showed different features and therapeutic response in comparison to previously reported features of MNV in age-related macular degeneration (AMD) without GA. For these reasons, the combined phenotype (ie, GA with neovascular AMD) should be considered as a distinct entity in the research and clinical setting.

Abstract
PURPOSE To describe the clinical and multimodal imaging (MMI) features of age-related macular degeneration (AMD) eyes presenting with intraretinal exudation and no evidence of neovascularization or structural alterations of native retinal vessels. METHODS This was a retrospective review of the MMI and electronic health records for 3 consecutive patients presenting with unilateral exudative non-neovascular age-related macular degeneration. MMI included confocal color fundus photography (CFP), fundus autofluorescence (FAF), fluorescein angiography (FA), spectral domain optical coherence tomography (SD-OCT), swept-source optical coherence tomography angiography (SS-OCTA), and spectral domain optical coherence tomography angiography (SD-OCTA). Dense B-scan OCTA (DB-OCTA) patterns and implemented image post-processing were used to improve spatial resolution in the OCTA analysis and remove projection artifacts. RESULTS Three eyes of 3 patients (1 male and 2 females, ages 72-87) developed intraretinal fluid (IRF) producing retinal edema during regular follow-up for non-neovascular AMD. FA, SS-OCTA, and DB-OCTA demonstrated no evidence of macular neovascularization or discrete retinal vascular abnormalities that could explain the IRF accumulation. Two eyes received intravitreal anti-VEGF therapy and demonstrated prompt resolution of IRF with periodic recurrences over time. CONCLUSION Exudative non-neovascular AMD is a novel clinical phenotype characterized by the presence of non-neovascular intraretinal exudation producing macular edema. Differentiating this condition from other manifestations of AMD requires appropriate use of MMI. Further study is needed to assess the clinical impact and optimal management of exudative non-neovascular AMD.

Abstract
BACKGROUND OCT angiography (OCT-A) allows non-invasive blood flow registration of the retina and choroid. In contrast to fluorescein angiography (FA), no dye has to be administered. The OCT-A also provides depth-selective information. OCT-A and FA were compared in patients with neovascular age-related macular degeneration (AMD) with retinal angiomatous proliferation (RAP) stage 1. In stage 1, the neovascularizations are intraretinal. In contrast to the two-dimensional total image of the FA, the OCT-A allows a depth-selective display of the individual retinal layers. In this way, a conclusion can be drawn about the place of origin of the RAP. PATIENTS AND METHODS Three patients with neovascular AMD and RAP stage 1 were included. They were examined with OCT (ZEISS CIRRUS HD-OCT 5000, Carl Zeiss Meditec, Inc., Dublin, USA), OCT-A (ZEISS AngioPlex OCT-Angiography) as well as FA (HRA2, Heidelberg Engineering) between January 2016 and March 2019. A complete ophthalmological examination was performed. A qualitative analysis of the OCT-A images (3 × 3 and 6 × 6 mm) and the FA images was carried out. Leaks in the FA were compared with the en-face images of the OCT-A followed by a depth-selective assignment using the corresponding B-scans of the OCT-A. RESULTS It was one woman and two men aged 66 - 89 years. The visual acuity was 0.4 in the first, 0.5 p in the second and 0.8 in the third patient. The diagnosis of RAP stage 1 could be made both in the OCT, the FA and the OCT-A. All patients showed macular edema in the OCT. The FA showed selective hyperfluorescence in the early phase and fluorescein extravasation in the late phase. In OCT-A, the blood flow in all patients could be shown in the hyperreflective structure of the RAP in the B-scan. The first patient showed two RAP lesions in the FA, which were in the deep vascular plexus in the OCT-A. In the second patient, three RAP lesions were found in the FA, and a total of five RAP lesions in the OCT-A. One could be located in the superficial and deep vascular plexus, four in the deep vascular plexus. The third patient showed one RAP lesion in the FA as well as in the OCT-A, which could be assigned to the superficial vascular plexus. CONCLUSION The OCT-A is well suited for the diagnosis of RAP stage 1. In the present cases, the diagnosis in the OCT-A could be made as clearly as by FA. A major advantage of the OCT-A results from the non-invasive character and the depth selectivity. The RAP 1 lesions could be assigned to both the superficial and the deep vascular plexus. Depth selection is not possible with the FA due to the summary picture.
