Abstract
PURPOSE To further enhance understanding of the expanded clinical spectrum of unilateral retinal pigment epithelium dysgenesis (URPED) via numerous imaging modalities including novel markers of highly detailed indocyanine green angiography (ICGA) features. METHODS Retrospective, observational, case report. RESULTS URPED in this patient is expressed as a solitary, flat and pigmented lesion in the posterior pole with RPE hyperplasia and atrophic changes. An epiretinal membrane (ERM) causing fine, tortuous retinal vessels and retinal folds was observed. Green and blue excitation light fundus autofluorescence showed a biphasic appearance with hypoautofluorescent rounded lesions and a reticular configuration of normal RPE. Fundus fluorescein angiography revealed diffuse hypofluorescence and hyperfluorescent wisps of leakage in late-phases. Early-phase of ICGA evidenced diffuse hypocianescence and a delineated hypercianescent scalloped margin appeared in the late-phase, together with focal hypocianescent spots. SD-OCT demonstrated irregularity of the RPE with fibrosis and hyperplastic changes combined with atrophic areas. Flat RPE detachments intermingled with healthy-appearing RPE were also observed together with thinning of the outer retina. ERM with thickening and disorganization involving the whole retina was present. Optical coherence tomography angiography (14 × 14 mm) revealed an oval shape foveal avascular zone and vascular anomalies such as tortuosity and looping. CONCLUSION URPED is an extremely rare clinical entity with only a few cases reported. In this case the almost pathognomonic differential features of URPED were best appreciated with ICGA imaging. To our knowledge, this is the first reported case of URPED with these abnormal findings on ICGA meaning it could be part of the spectrum of the disease.

Abstract
PURPOSE To characterize the occurrence of diabetic macular edema and the presence of abnormal retinal fluid accumulation in nonproliferative diabetic retinopathy (NPDR). METHODS In this two-year prospective study, a total of 122 eyes with diabetes type 2 underwent optical coherence tomography (OCT) and OCT-Angiography in association with OCT-Fluid imaging, a novel algorithm of OCT analysis allowing quantification of abnormal accumulation of fluid in the retina through low optical reflectivity ratios (LOR). Early Treatment Diabetic Retinopathy Study (ETDRS) grading for diabetic retinopathy (DR) severity assessment was performed using 7-field color fundus photography. Best corrected visual acuity was also recorded. RESULTS During the 2-year follow-up, 23 eyes (19%) developed central-involved diabetic macular edema (CI-DME) and 2 eyes (2%) developed clinically significant macular edema (CSME). In the two-year period of the study, eyes that developed CI-DME showed a progressive increase in central retinal thickness (CRT) (β = 7.7 ± 2.1 µm/year, p < 0.001) and in LOR values (β = 0.009 ± 0.004 ratio/year, p = 0.027). The increase in CRT and abnormal retinal fluid, represented by increased LOR ratios, are associated with increased retinal perfusion in the deep capillary plexus (DCP) (skeletonized vessel density, p = 0.039). In contrast, the eyes with CSME showed decreased retinal perfusion and abnormal fluid located in the outer layers of the retina. CONCLUSIONS CI-DME and CSME appear to represent different entities. Eyes with CI-DME show increases in abnormal retinal fluid associated with increased retinal vascular perfusion in the DCP. Eyes with CSME are apparently associated with decreased retinal vascular perfusion in the DCP and abnormal fluid in the outer retina.

Abstract
OBJECTIVE To evaluate the macular microvascular changes using optical coherence tomographic angiography (OCT-A) in children with unilateral amblyopia and their reversibility during treatment. METHODS Patients with unilateral strabismic or anisometropic amblyopia or residual amblyopia from early congenital cataract surgery, examined between October 2019 and March 2021, were included. Vessel density and perfusion density in the superficial capillary plexus and area, perimeter and circularity of the foveal avascular zone (FAZ) were analysed using OCT-A in amblyopic eyes, contralateral eyes and control group healthy eyes. Correlation analyses between the microvascular parameters and the visual acuity were performed. In a pilot study on a few patients from the amblyopic cohort, longitudinal follow-up during treatment was also performed. RESULTS A total of 128 eyes of 64 patients were included: 32 amblyopic eyes compared with 32 contralateral eyes and 64 control eyes. Vessel density and perfusion density in the superficial capillary plexus were significantly lower in amblyopic eyes compared to control eyes in 6 × 6 mm (p < 0.02) and 3 × 3 mm (p < 0.01) scans. Correlation analyses showed a linear decrease in vessel density and perfusion density with decreasing visual acuity. The microvascular changes observed were reversible with the occlusion treatment of amblyopia (p < 0.001). CONCLUSIONS The study found a decrease in vessel density and perfusion density in the macula of children with unilateral functional amblyopia. These microvascular changes were correlated with visual acuity and appeared to be reversible with treatment of amblyopia. On the whole, OCT-A appears to be a relevant complementary examination when it comes to diagnosing and monitoring functional amblyopia.

Abstract
INTRODUCTION There are no reports in the literature studying the possible relationship between Epstein-Barr virus (EBV) and optic nerve involvement in multiple sclerosis (MS). The aim of our study was to analyze the association between EBV antibodies titres and optical coherence tomography (OCT) and OCT angiography (OCTA) quantitative parameters. METHODS We conducted a retrospective study. The study included 98 eyes of 49 patients with MS. Years of MS duration, relapse count, history of optic neuritis (ON), and immunoglobulin (Ig) G antibodies to the EBV viral capsid antigen (VCA) were recorded from each patient. Also, OCT analysis (including retinal nerve fibre layer (RNFL) thickness and ganglion cell-inner plexiform layer (GCIPL) thickness) and OCTA analysis (including perfusion density (PD) and flux index (FI) of the radial peripapillary capillary plexus) were performed in each participant. RESULTS No significant associations were observed between anti-EBV antibody levels and OCT or OCTA parameters (p > 0,05). Correlation analysis between OCT and OCTA measurements showed a significant positive correlation between RNFL thickness and GCIPL thickness with peripapillary PD and FI (p < 0,035). Subgroup analysis revealed a significant diminution of RNFL thickness, GCIPL thickness and peripapillary PD and FI (p < 0,05) in the ON group. CONCLUSION We were unable to demonstrate a significant association between anti-EBV VCA IgG antibody titres and OCT or OCTA parameters. Nonetheless, further longitudinal studies are needed to explore the possible association of EBV with optic nerve involvement in MS.

Abstract
INTRODUCTION Evidence on peripapillary microvasculature in intracranial hypertension (IH) after the regression of papilledema is still scarce. The aim of this preliminary study was to determine the association between structural changes in the optic nerve and the retina and peripapillary microvasculature in patients with IIH. METHODS We conducted a retrospective study. The study included 39 eyes of 21 patients with IIH. Treatment for IIH and history of obesity were registered from each patient. Moreover, OCT analysis including retinal nerve fiber layer (RNFL) thickness and ganglion cell-inner plexiform layer (GCIPL) thickness, and OCTA analysis including perfusion density (PD) and flux index (FI) of the radial peripapillary capillary plexus were performed. RESULTS Correlation analysis revealed a high correlation between GCIPL thickness and peripapillary PD and FI (p < 0,05, r > 0,7), whereas the degree of correlation between RNFL thickness and peripapillary microvascular parameters was low (p < 0,05, r < 0,7). Patients with regressed papilledema had significantly lower GCIPL thickness and peripapillary PD than control subjects (p < 0,05). CONCLUSION Peripapillary microvascular measurements are highly correlated with GCIPL thickness in patients with IIH. Moreover, GCIPL thickness and peripapillary PD are significantly inferior in patients with regressed papilledema compared to control group. Thus, we suggested that peripapillary microvascular parameters may be an early indicator of optic nerve atrophy in patients with IIH.

Abstract
BACKGROUND To evaluate the correlations between anatomical and functional changes after idiopathic epiretinal membrane (iERM) surgery. METHODS In this prospective, observational, single-center study, consecutive patients who underwent iERM peeling were enrolled. Reported data were pre- and postoperative best-corrected visual acuity (BCVA), retinal sensitivity (RS) and fixation stability values on microperimetry, structural macular features on SD-OCT and OCTA. RS of foveal and parafoveal area was analysed and two sub-groups were identified whether RS improved or remained unchanged/worsened after surgery; consequently, vascular perfusion density (VPD) of the same area was studied. RESULTS Twenty-nine eyes of 29 patients were examined. The post-operative improvement in terms of BCVA, RS and fixation within the central 4 degrees was significant (p < 0.001, p < 0.001, p = 0.001), as well as the foveal thickness and macular volume change/reduction (p < 0.001). The pre-operative superficial VPD, choriocapillaris VPD and capillary free zone (CFZ) area were significantly reduced compared to the fellow healthy eye (p = 0.001, p = 0.02, p < 0.001). Choriocapillaris VPD showed a statistically significant increase after surgery (p < 0.02). Superficial, deep and choriocapillaris VPD of the improved RS group showed a significant increase both in foveal (p = 0.03, p = 0.03, p = 0.01) and parafoveal areas (p = 0.01, p = 0.03, p = 0.001). CONCLUSIONS We reported a higher VPD in the retinal area that experienced a retinal sensitivity improvement 6 months after ERM surgery. This result objectifies the tight bond between visual function and retinal perfusion in ERM patients.

Abstract
AIM Our aim is to report a case with bilateral Waldenström's macroglobulinemia (WM) associated maculopathy, assessed with multimodal imaging including swept source optical coherence tomography (SS-OCT) and OCT-Angiography (OCT-A). METHODS Observational case report. CASE PRESENTATION A 61-year-old diabetic woman with history of treated WM currently in remission, presented with progressive bilateral visual loss. Best-corrected visual acuity was 20/100 in the right eye (RE) and 20/200 in the left eye (LE). Fundus examination showed bilateral microaneurysms and retinal punctuate hemorrhages and a large macular serous detachment in the LE. There was no retinal ischemia on FA nor macular dye leakage. SS-OCT showed a significant schisis-like intraretinal fluid accumulation in the RE and a large prominent macular detachment with significant subretinal fluid accumulation in the LE. Retinal and choriocapillaris vascular densities were normal on OCT-A. CONCLUSION Our case illustrated characteristic multimodal imaging findings in WM associated maculopathy such as schisis-like intraretinal fluid accumulation and angiographically silent serous macular detachment. OCT-A could non-invasively analyze macular vascular densities layer-by-layer, without noticing any vascular anomaly.

Abstract
INTRODUCTION The purpose of this investigation was to report swept source-optical coherence tomography angiography (SS-OCTA) quantitative information of retinal and choroidal microvascularization in patients with dyslipidemia (DL). METHODS We performed a retrospective study. The study enrolled 37 eyes of 20 patients with DL and 40 eyes of 23 healthy subjects. OCTA quantitative parameters (vessel density (VD) and foveal avascular zone (FAZ) area of superficial capillary plexus (SCP), middle capillary plexus (MCP), deep capillary plexus (DCP) and choriocapillaris (CC)) in 6 mm × 6 mm and 4,5 mm × 4,5 mm cubes were recorded. RESULTS No differences in VD in SCP, MCP and DCP were demonstrated between DL group and control group (p > 0,05). Conversely, VD in the central region at CC was diminished in patients with DL in both cubes (p < 0,05). Moreover, total VD in CC was decreased in the DL group in 6 mm × 6 mm cube (p < 0,05). Regarding FAZ area, we demonstrated and enlargement of FAZ in each retinal capillary plexus, but it did not reach statistical significance (p > 0,05). CONCLUSION We objectified a diminution of VD in the CC, suggesting that DL mainly affects the choroidal microvasculature. Nonetheless, further studies with a larger population are needed.

Abstract
PURPOSE 25-hydroxyvitamin D [25(OH)D] sufficiency has critical biological importance for the human body. Although there are several studies on the association between serum 25(OH)D levels and macular structure, the data in this regard are limited. This study mainly aimed to investigate macular microvascular structure using optical coherence tomography angiography (OCTA) in 25(OH)D deficiency. STUDY DESIGN Prospective, single-center, clinical study. METHODS The study included 82 eyes of 82 patients with 25(OH)D deficiency (Group I) and 50 eyes of 50 healthy subjects (Group II). All participants underwent OCTA examinations. The foveal avascular zone (FAZ) and superficial capillary plexus (SCP) and deep capillary plexus (DCP) vessel density (VD) measurements of the participants were statistically compared between the patients and healthy subjects. RESULTS The mean 25(OH)D levels measured from the venous blood samples of the participants were 7.61 ± 3.27 ng/mL in Group I and 25.39 ± 4.16 ng/mL in Group II, and the difference between these values was statistically significant (p < 0.0001). The FAZ measurement was significantly higher in Group I. The VDs of the SCP and DCP measurements were significantly higher in Group II. When the central macular thickness values of the participants were compared, Group II had a significantly higher value, but there was no significant difference in the central macular volume and retinal nerve fiber layer thickness analyses. CONCLUSION The results showed that the FAZ area was significantly higher and the VDs of SCP and DCP were significantly lower in the patients with 25(OH)D deficiency. We found that 25(OH)D deficiency affected macular microvascular architecture.

Abstract
INTRODUCTION There is only a unique report with a small sample size studying hydroxychloroquine (HCQ) retinal toxicity with swept-source (SS) optical coherence tomography angiography (OCTA). The aim of this study was to quantify OCTA quantitative parameters in patients who underwent HCQ therapy. METHODS We conducted a retrospective study. The study included 43 eyes of 22 patients taking HCQ for more than 5 years (high-risk group), 57 eyes of 29 patients taking HCQ for 5 years or less (low-risk group) and 25 eyes of 50 age-matched healthy controls. OCTA quantitative parameters (vessel density (VD) and foveal avascular zone (FAZ) area in superficial capillary plexus (SCP), middle capillary plexus (MCP), deep capillary plexus (DCP), total capillary plexus (TCP), and choriocapillaris (CC)) were recorded. RESULTS In the low-risk group, VD in the SCP and MCP was increased compared to control group (p value <.05). In the high-risk group, VD in the SCP, MCP and TCP was increased (p value <.05). The subgroup analysis revealed an increased VD at SCP in systemic lupus erythematosus (SLE) high-risk patients, an increased VD at TCP and CC in rheumatoid arthritis (RA) high-risk subjects, and a decreased VD at CC level in the high-risk group patients with Sjögren's syndrome (SS) and connective tissue disease (CTD) (p value <.05). Furthermore, we demonstrated a significant enlargement of FAZ area at MCP level in the high-risk group patients with SS and CTD (p value <.05). CONCLUSION We demonstrated an increase of VD in patients who underwent HCQ treatment, so we suggest that HCQ retinal toxicity is not vascular mediated.

Abstract
PURPOSE To report 12-year follow-up of a patient with ARB. CASE REPORT A 25-year-old man presented with blurred vision in his both eyes (OU). Best-corrected visual acuity (BCVA) was 20/63 Snellen equivalent in the right eye (OD) and 20/32 Snellen equivalent in the left eye. The intraocular pressures and anterior segment examination were unrevealing in OU. Posterior segment examination revealed multiple yellowish flecks and dots in the posterior pole in OU. Optical coherence tomography (OCT) showed subretinal fluid (SRF), intraretinal hyporeflective spaces, elongated and shaggy photoreceptors and outer retinal defects. Fundus autofluorescence demonstrated mottling hyperautofluorescence and hypoautofluorescence in the posterior pole in OU. Fluorescein angiography illustrated hyperfluorescence in the posterior pole and surrounding the arcades in OU. Multifocal electroretinography objectified mild to markedly abnormal responses in all ring areas in OU. Molecular genetic testing confirmed two heterozygous sequence variations in the BEST1 gene. At 4 years of follow-up, OCT revealed a complete resolution of SRF and a partial resolution of intraretinal hyporeflective spaces in the OD with corresponding improvement in the BCVA to 20/23 Snellen equivalent in the OD, even though outer retinal defects persisted. Our patient denied recent changes in his alimentary habits and medical history at that time. Posteriorly, SRF and intraretinal hyporeflective spaces reappeared in the OD. CONCLUSION To the best of our knowledge, this is the first case report of ARB with a transient resolution of retinal edema in one eye without medical treatment and dietary therapy.

Abstract
Retinitis punctata albescens (RPA) is generally diagnosed by the presence of numerous clusters of white punctate lesions in the retina that progress over time and are related to several gene variants. The multifocal variant of congenital hypertrophy of the retinal pigment epithelium (CHRPE) is characterized by multiple, grouped, sharply circumscribed, pigmented spots. The PRPH2 gene encodes a photoreceptor-specific glycoprotein, which is essential for the morphogenesis of rod and cone photoreceptor outer segments. A 39-year-old Chinese female with nyctalopia, complained about blurred vision, presented a unique co-existing feature of RPA and CHRPE. Dilated fundus exam demonstrated numerous porcelain white discrete dots in both eyes and multiple, small, flat clusters of round brown to black pigmented lesions in the left eye. The full field electroretinography (ERG) showed decreased responses after standard dark adaptation and normal b-wave amplitudes after a long (4-h) dark-adapted period. A heterozygous PRPH2 splicing variant was detected in the proband. In addition, the same variant was found in her mother, her son, and her daughter. We describe a PRPH2 variant in a rare case of RPA associated with multifocal CHRPE of the same individual.

Abstract
INTRODUCTION Choroidal rupture is a tear/break within the Bruch's membrane, retinal pigment epithelium and choroid following blunt trauma. Choroidal neovascularization is a well-known complication of traumatic choroidal rupture that is typically treated with intravitreal injections of Bevacizumab. This case describes an early detection of choroidal neovascular complex secondary to traumatic choroidal rupture and its spontaneous regression and quiescence without treatment followed using optical coherence tomography (OCT) angiography. CASE DESCRIPTION A healthy 19 year old female presented with decreased vision in her left eye following a blunt non-penetrating closed globe injury two weeks prior. A complete ophthalmic examination with ancillary testing was consistent with sub-foveal choroidal neovascularization secondary to traumatic choroidal rupture. Five weeks later, there was spontaneous regression of the choroidal neovascular complex as depicted on OCT angiography and complete resolution of subretinal fluid/exudation on structural OCT. A conservative approach without intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections was chosen for management. CONCLUSION To the authors' knowledge this is a first case describing a unique evolution with spontaneous regression and quiescence of choroidal neovascularization secondary to traumatic choroidal rupture without treatment followed using OCT angiography. Expectant management may be a viable treatment option for this condition.

Abstract
PURPOSE To evaluate the microvascular changes in the macular and peripapillary area after intravitreal dexamethasone implant in diabetic macular edema (DME). MATERIAL AND METHODS We included 31 eyes of 31 patients treated with a single dose dexamethasone implant for DME. All subjects underwent swept-source optical coherence tomography (OCT) and OCT angiography imaging before (T0), and one month (T1), two months (T2), and four months (T4) after dexamethasone injection. The foveal avascular zone (FAZ) area of superficial and deep capillary plexus (SCP and DCP) was calculated by delineating the FAZ border using the measurement tool of the device. The vessel density (VD) of SCP and DCP and choriocapillaris (CC) in the macular and peripapillary area were automatically calculated. RESULTS There was an insignificant reduction in FAZ area measurements of SCP after dexamethasone injection in DME patients (p = 0.846). The FAZ area of DCP were significantly smaller compared to T0 measurements at T1, T2, and T4 (p = 0.013, p = 0.031, and p = 0.029, respectively). The mean average parafoveal VD measurements were significantly decreased after dexamethasone injection in SCP and DCP (p = 0.004, p = 0.005). The peripapillary VD in retinal capillary plexuses and choriocapillaris showed no significant difference after dexamethasone injection. CONCLUSION Intravitreal dexamethasone leads to a significant FAZ area decrease in DCP with a reduction in parafoveal VD measurements. In addition, no significant VD changes were observed in the peripapillary area after dexamethasone. These findings indicate that dexamethasone may improve macular ischemia with no significant effects on peripapillary microvasculature in DME patients.

Abstract
INTRODUCTION To evaluate the detection rate of aneurysmal type 1 neovascularization (AT1) in Caucasian patients using optical coherence tomography angiography (OCTA) and to describe OCTA characteristics of AT1 in a cohort of white patients. METHODS We conducted an observational retrospective study in 44 eyes of 43 patients with AT1. All patients underwent a complete ophthalmologic examination, including fundus imaging, indocyanine green angiography, optical coherence tomography, and OCTA. Branching vascular network (BVN) and polyp detection rates by OCTA were evaluated. Furthermore, we described BVN and polyp morphologies on en face OCTA and flow of polyps on B-scan OCTA. RESULTS En face OCTA revealed BVN in 84.09% of cases and polypoidal lesions in 86.36% of cases. B-scan OCTA showed BVN and polyps in 95.45% and 93.18% of the patients, respectively. "Trunk" BVNs (51.35%) and "ring" polyps (47.37%) were the most frequent morphologies observed in our cohort, and "patchy hyperflow" (80.49%) signal was the most common visualized in our patients. Regarding OCT parameters, CT under polyps was higher in patients with positive detection of polyps on B-scan OCTA. CONCLUSION OCTA is a possible diagnosis tool in Caucasian patients with AT1. To the best of our knowledge, this is the largest study performed in Caucasian patients regarding OCTA diagnostic abilities and features.

Abstract
INTRODUCTION There is a lack of information on quantitative parameters of optical coherence tomography angiography (OCTA) in cases of chorioretinal folds (CRF). The aim of this study was to compare OCTA retinal and choriocapillary vessel density (VD) between normal subjects and patients with CRF. METHODS We conducted an observational retrospective study. A total of 16 eyes of eight patients were recruited (eight eyes with CRF and eight control eyes). Data on best-corrected visual acuity (BCVA), refractive error, central macular thickness (CMT), central subfoveal thickness (CST), and OCTA findings (VD and foveal avascular zone (FAZ) area in superficial capillary plexus (SCP), middle capillary plexus (MCP), and deep capillary plexus (DCP), and VD in choriocapillaris (CC)) were recorded in each eye. RESULTS Compared with control group, CRF group showed decreased VD in the foveal region of SCP and MCP (p value 0.003 and 0.001), and increased VD in nasal region of SCP and MCP (p value 0.02 and 0.001), and in parafoveal area of MCP (p value 0.005). No differences were found in DCP and CC layers. Furthermore, we observed an enlargement of FAZ in CRF group at SCP and MCP slabs (p value <0.001 and 0.015). Respect to optical coherence tomography parameters, we demonstrated a thicker choroid in the CRF group (p value 0.002). CONCLUSION To the best of our knowledge, this is the first study reported in the literature quantifying VD of retinal capillary plexus and CC in a group of patients with a diagnosis of CRF secondary to hyperopia.

Abstract
PURPOSE To report a case of vitamin A retinopathy secondary to Billroth II anastomosis triggered after the beginning of dialysis in a patient with a chronic renal failure. CASE REPORT A 73-year-old male complained of nyctalopia that had started 9 months ago, coinciding with the beginning of dialysis. His medical history is remarkable for hepatic cirrhosis and Billroth II anastomosis 20 years ago. Best-corrected visual acuity (BCVA) was 60 letters in both eyes. Dilated fundus examination showed faint white-yellowish dots. Optical coherence tomography (OCT) illustrated hyperreflective dots and small hyporreflective cavities between the retinal pigment epithelium (RPE) and the ellipsoid zone (EZ). En face OCT showed multiple hyperreflective dots that coincide with white-yellowish dots of the fundus, and multiple hyporreflective defects which correspond to hyporreflective cavities seen in the OCT. Visual field examination showed concentric narrowing of the visual field. A diagnosis of vitamin A deficiency was confirmed and oral vitamin A supplementation was initiated. One month after treatment, the patient reported a subjective improvement of nyctalopia, and BCVA ameliorated up to 80 and 85 letters. Fundus examination, OCT, and en face OCT showed a diminution of the observed lesions. Moreover, visual field improved. CONCLUSION Early diagnosis of vitamin A deficiency can prevent irreversible visual sequelae. This highlights the crucial role of ophthalmologists in the prompt detection of this condition. A lifelong monitoring should be needed in patients undergoing biliopancreatic diversion surgery. Furthermore, OCT and en face OCT becomes a main tool in the diagnosis and monitor response to treatment.

Abstract
PURPOSE The water drinking test (WDT) is a well-known stress test that increases intraocular pressure (IOP) momentarily and can indicate risk of glaucoma progression. This study focuses on correlating changes in the retinal microvascular plexus with the WDT in young healthy subjects. METHODS A total of 20 eyes of 20 healthy young subjects (mean age 24.37 ± 2.17 years) were included in this study. In our protocol, WDT consisted of drinking 1 L of water within 5 min. Outcome measures in this prospective observational study were mean arterial pressure (MAP), heart rate (HR), IOP, and retinal vessel density of both superficial and deep macular retina using optical coherence tomography angiography (OCTA), which were assessed before water ingestion and four times after at 15-min intervals. OCTA images were later quantified by fractal analysis (box counting [Dbox]). One-way repeated measures analysis of variance (ANOVA) was used to assess the effects of WDT on each of the parameters. RESULTS The WDT resulted in significant peak changes of the following parameters compared to baseline: IOP: 15.63 ± 3.37 versus 18.38 ± 4.53 mmHg at 30 min, p < 0.001; HR: 75.74 ± 12.23 versus 64.95 ± 11.37 bpm at 15 min, p < 0.001; deep retinal vessel density 1.758 ± 0.14 versus 1.749 ± 0.16 at 15 min, p = 0.040. CONCLUSIONS Besides IOP elevation and systemic effects in HR, WDT is associated with temporary modifications of the deep vascular plexus in young healthy subjects.

Abstract
The external limiting membrane (ELM) and ellipsoid zone (EZ) can be observed exquisitely by SD-OCT. In diabetic macular edema (DME), dysfunction of mitochondria, represented by the EZ in the foveal photoreceptors results in reduced visual acuity (VA). An increase in VEGF was found to correlate with increased severity of DR, increased central subfield thickness (CST), and sequential disruption of ELM and EZ. The mechanism of ELM and EZ restoration after anti-VEGF therapy in DME has been discovered. The ELM restores first followed by EZ restoration. Thus, authors have discovered and established ELM as a novel retinal structural barrier.

Abstract
PURPOSE To describe an unusual variant of central serous chorioretinopathy (CSC) presenting as a choroidal elevation with subretinal fluid and its response to accepted treatment modalities of CSC. DESIGN A retrospective case series. SUBJECTS Six eyes of three patients, two males and one female, with a mean age of 55.3 years, were included in the study. All of them had Pachychoroid features, solitary choroidal elevation and subretinal fluid on optical coherence tomography (OCT); none of the patients had a previous episode of CSC. METHODS Patients were studied with biomicroscopy, ultrasonography, fluorescein angiography and indocyanine green angiography. Systemic evaluation to rule out inflammatory and infective pathologies, and an oncologist referral also was done. Patients were managed in the line of central serous chorioretinopathy, using conservative treatment, focal laser and oral eplerenone. MAIN OUTCOME MEASURES Resolution of subretinal fluid and choroidal elevation. RESULTS Complete resolution of choroidal elevation and subretinal fluid was noted in all the three patients. There was no recurrence till the end of follow-up. CONCLUSION Pachychoroid disease may present as solitary choroidal elevation with subretinal fluid due to exaggerated posterior choroidal fluid loculation and has a favourable outcome. However, it should be considered after exclusion of other differential diagnoses.

Abstract
PURPOSE To determine whether there is a significant correlation between the retinal sensitivity and the integrity of the ellipsoid zone (EZ) of the photoreceptors in eyes with myopic chorioretinal atrophy (CRA). We also determined the significance of the correlation between the retinal sensitivity and the retinal and choroidal thicknesses. METHODS The medical records of 10 eyes of six subjects with myopic CRA were reviewed. The integrity of the EZ was determined in the spectral-domain optical coherence tomographic (OCT) images at 37 points of six scans corresponding to the locations where the retinal sensitivities were measured by MP-3 microperimetry. The mesopic retinal sensitivities were determined within the central 16°. The significance of the correlations between the integrity of the EZ and the mesopic retinal sensitivities was determined. The relationships between the retinal and choroidal thickness and the retinal sensitivity were also determined. RESULTS The average age of the patients was 70.0 ± 6.7 years, and the average axial length of the eye was 29.2 mm. The mesopic sensitivities at the points where the EZ was present were significantly higher than those where the EZ was absent (p < 0.01). The mesopic sensitivity was significantly correlated with the retinal thickness (p < 0.01, r = 0.30) and the choroidal thickness (p < 0.01, r = 0.23). CONCLUSIONS The significant correlation between the mesopic retinal sensitivity and the integrity of the EZ indicates that the mesopic sensitivities can be used to assess the integrity of the photoreceptors in eyes with myopic CRA.

Abstract
PURPOSE To report multimodal imaging findings including optical coherence tomography angiography (OCT-A) of a patient presenting with a quiescent choroidal neovascularization (CNV) in one eye and an active CNV in the fellow eye, complicating retinitis pigmentosa (RP) linked to PRPH2 pathogenic variant, with follow-up and management of both eyes. METHODS Observational case report. RESULTS A 40-year-old female with history of autosomal dominant RP consulted for acute visual loss in her right eye (RE). Multimodal imaging including OCT-A confirmed the diagnosis of active type 2 CNV in the RE and highlighted an incidental asymptomatic non-exudative "quiescent" CNV in the left eye (LE). This complication was managed by intra-vitreal Bevacizumab injections in the RE and regular monitoring of the LE. Frequent follow-up could detect early CNV activation signs in LE allowing early treatment. Mutation analysis of PRPH2 exons identified a known heterozygous pathogenic missense variation c.646C>T, p.P216S in exon 2. CONCLUSION Multimodal imaging and especially OCT-A can be of a great help in the diagnosis and the management of CNV complicating RP, even at the stage of quiescent CNV. In presence of neovascular complication, PRPH2 gene should be investigated because of its frequent macular involvement despite high phenotypic variability.

Abstract
INTRODUCTION There are a few reports investigating the treatment of aneurysmal type 1 neovascularization (AT1) in Caucasian patients. The aim of this study is to evaluate the 2-year results of a treat and extend regimen with aflibercept in Caucasian patients with AT1. METHODS We conducted an observational retrospective study in 28 eyes of 26 patients with naïve AT1 treated with a treat an extend regimen of intravitreal aflibercept. Best corrected visual acuity (BCVA), central macular thickness (CMT), pigment epithelium detachment (PED) height, presence of dry macula, and regression rate of polypoidal lesions were assessed at baseline and at 12 and 24 months. RESULTS BCVA was significantly increased by 9.03 ± 16 letters (p < 0.01) and 9.2 ± 16.87 letters (p < 0.01) after the 12 and 24 months follow-up. A significant decrease of CMT was found at 12 and 24 months (p < 0.01). Nevertheless, significant changes in PED height were not observed (0.1 < p > 0.05). At 12 and 24 months of follow-up, dry macula was achieved in a total of 10 eyes (35.71%) and 15 eyes (53.57%). The regression rate of polypoidal lesions was 25% (7 eyes) and 35.71% (10 eyes) after 12 and 24 months. The mean number of intravitreal injections was 7.81 ± 3.20 the first year and 6.11 ± 3.49 the second year. CONCLUSION To the best of our knowledge, treat and extend regimen with intravitreal aflibercept in Caucasian patients may be effective for improving BCVA, CMT, wet macula, and regression rate of polypoidal lesions.

Abstract
PURPOSE The principal aim of this pilot study was to investigate the concordance between the different stages of Age-Related Macular Degeneration (AMD), as determined by the simplified classification of the Age Related Eye Disease Study Group (AREDS), and new evaluation criteria using a microperimetry system. METHODS A complete eye examination and a microperimetry MAIATM (Macular Integrity Assessment, CenterVue, Padova, Italy) examination was performed on 59 eyes with early, intermediate or advanced AMD. We analysed 19 evaluation criteria for every clinical group category. RESULTS There were 20 female and 12 male participants included with a median age of 74 years (min: 54, max: 87). Thirteen eyes (22%) were classified as category 1, 11 eyes (18.6%) as category 2, 17 eyes (28.8%) as category 3 and 18 eyes (30.6%) as category 4 AMD.All evaluated microperimetry criteria related to retinal sensitivity were found to have a statistically significant difference among the stages (p < 0.05). Fixation stability was unstable in 55.6% of the eyes classified as stage 4 (p = 0.001). The analysis of the distance between the two PRLs - PRL_initial and PRL_final was larger for the stage 4 (p = 0.0258). The mean sensitivity in stages 2 and 3 correlated with the presence or not of reticular pseudodrusen (p = 0.0137). CONCLUSIONS The mean sensitivity and the categorized sensitivity (set to 25, 15 and 5 dB), the five higher and lower stimuli sensitivity appeared to be the most sensitive criteria to differentiate the four AMD categories. Microperimetry provides a new reproducible method of anatomical-functional macular analysis.

Abstract
PURPOSE We aim to provide a description of the optical coherence tomography findings in the outer macula hyperreflective bands of our patients with X-linked juvenile retinoschisis. Also to categorize these changes and to quantitatively and qualitatively correlate their reflectivity levels with visual function. METHODS We manually segmented the borders, and depicted relative intensity of the inner segment ellipsoid band, and quantified the volume of edema. RESULTS The average relative intensity of the ellipsoid zone, ISe band, for the control subject was 14.864, our patient's, with the mild disease was, 28.238 and 34.943 in OD and OS, respectively, and for the patient with severe disease was, 44.442 and 40.154 for OD and OS respectively. Thresholding showed a significant difference in edema volume between mild disease (~20%), and severe form (~50%). Relative intensity analyses are indicative of homogeneity variability. High standard deviation value illustrates the high dispersion of data values and is a safe marker of ellipsoid zone homogeneity. CONCLUSION Data suggested that both anatomic and functional characteristic of outer macula hyperreflective bands were notably associated with the pathogenesis cascade in the photoreceptor cells. External limiting membrane line disruption is initiated by the volume of macular edema and followed by disorganization of the three lines in a stepwise pattern, first at the ellipsoid zone, followed by the cone outer segment tips zone and finally at the External limiting membrane.

Abstract
PURPOSE To report multimodal imaging characteristics of two cases of retinal vein occlusion (RVO) secondary to Waldenstrom macroglobulinemia (WM). CASE REPORT Case 1: An 82-year-old woman presented with vision loss. She had a history of WM. Best-corrected visual acuity (BCVA) was 20/100 Snellen equivalent in the right eye (OD) and 20/63 in the left eye (OS). Fundoscopy showed bilateral hemorrhages in posterior pole and along superotemporal arcade. Fluorescein angiography illustrated no macular leakage. Optical coherence tomography (OCT) revealed macular edema (ME). Optical coherence tomography angiography (OCTA) demonstrated abnormalities in choriocapillaris. A diagnosis of bilateral branch RVO was made and ME was treated with intravitreal dexamethasone, achieving stability. Case 2: A 65-year-old man presented with venous dilation, tortuosity, and intraretinal hemorrhages. BCVA was 20/20 in both eyes (OU). OCT showed ME and hyperreflective dots in choroid. A diagnosis of bilateral central RVO was made. Laboratory evaluation and bone narrow biopsy confirmed a diagnosis of WM. After that, our patient consulted because of vision loss. BCVA was 20/400 in OU. Fundoscopy and OCT demonstrated a worsening of the intraretinal hemorrhages and the ME. OCTA showed damage of choriocapillaris. Thus, intravitreal dexamethasone and plasmapheresis was advised. Two months after, BCVA was 20/40 in the OD and 20/32 in the OS. Also, fundoscopy and OCT improved. CONCLUSION Early treatment of WM is truly important, with the aim of achieving a decrease in IgM levels in order to avoid toxic effect over the RPE that results in refractory ME.

Abstract
PURPOSE To describe the natural history of acquired vitelliform lesions (AVLs) associated with different types of pigment epithelial detachments (PEDs) in dry age-related macular degeneration. METHODS A retrospective review of clinical examination and multimodal imaging data of patients with AVLs associated with PED(s) was performed. RESULTS This study included 25 eyes of 17 patients. The mean age of patients was 67.2 ± 9.7 (47-83) years. The mean follow-up time was 32.6 ± 16.2 (12-66) months, excluding four patients (five eyes) that were lost to follow-up. The mean logMAR BCVA was 0.21 ± 0.16 at baseline and 0.38 ± 0.28 at final visit (p = 0.016). At the end of the follow-up period, PEDs enlarged in eight eyes (40%) and were unchanged in two eyes (10%). Spontaneous resolution of the central PED(s) with AVLs was seen in four (20%) eyes. Rupture of the PED(s) occurred in four eyes (20%), with two developing central foveolar atrophy afterwards. Overall, central foveolar atrophy was seen ultimately in four eyes (20%). CONCLUSION It seems that high PED size may be a risk factor for PED rupture during follow-up. 1/3 of the eyes ended up with unfavorable anatomical outcome.

Abstract
BACKGROUND/OBJECTIVES Continuous subcutaneous insulin infusion (CSII) is a treatment for type 1 diabetes that improves metabolic control and reduces micro and macrovascular complications. The aim of this study was to compare the effect of CSII versus traditional multiple daily injections (MDI) therapy on retinal vasculature. METHODS We performed a prospective study with type 1 diabetic patients with no prior history of ocular pathology other than mild diabetic retinopathy. The patients were divided into two groups according to their therapeutic modality (CSII vs MDI). The retinal nerve fiber layers thickness and vascular densities were compared between groups in both macula and optic disc. The correlations between vascular density and clinical features were also determined. Statistical significance was defined as p < 0.05. RESULTS The study included 52 eyes, 28 in the insulin CSII group. The mean age was 36.66 ± 12.97 years, with no difference between groups (p = 0.49). The mean glycated hemoglobin (HbA1c) was found to be lower in the CSII group (7.1% ± 0.7 vs 7.5% ± 0.7 p < 0.01). The parafoveal vascular density was found to be higher in the CSII group (42.5% ± 0.4 vs 37.7% ± 0.6, p < 0.01). We found an inverse correlation between HbA1c value and parafoveal vascular densities (p < 0.01, r = -0.50). CONCLUSION We found that CSII provided better metabolic control than MDI and this seemed to result in higher parafoveal vascular density. As lower vascular density is associated with an increased risk of diabetic retinopathy, these results suggest that CSII could be the safest therapeutic option to prevent retinopathy.

Abstract
PURPOSE To assess long-term vascular density measured by optical coherence tomography angiography (OCT-A) in former preterm children with history of retinopathy of prematurity (ROP) with and without need of laser treatment. METHODS This observational study included former preterm children that developed ROP stage 2 or 3. Infants were divided in two groups according to previous need of laser treatment, and underwent a complete ophthalmologic evaluation, including assessment of macular morphologic and vascular parameters by OCT-A. RESULTS Fifteen eyes were included in group 1 (laser-requiring ROP) and 19 in group 2 (non-treated ROP). Group 1 had lower mean gestational age and birth weight values than group 2 (p < 0.001 and p < 0.001, respectively). Best corrected visual acuity (BCVA) was lower in group 1 (0.08 ± 0.04 logMAR vs 0.04 ± 0.07 logMAR, p = 0.03). Laser-requiring ROP had lower vascular parameters, especially of central and internal vascular density (9.15 ± 2.75 vs 10.52 ± 0.86 mm-1, p = 0.05; 13.74 ± 1.00 vs 15.86 ± 0.64 mm-1, p = 0.05; respectively), and lower avascular zone circularity (0.58 ± 0.06 vs 0.76 ± 0.02, p < 0.001). Mean macular thickness was higher in group 1 (300.50 ± 10.50 vs 281.11 ± 2.50 μm, p = 0.05). Best corrected visual acuity (BCVA) was correlated with superficial vascular density (p < 0.05). CONCLUSION Laser-requiring ROP seems to result in a decrease of long-term BCVA, which is at least partially attributed to a decrease in superficial macular vascular density. However, prematurity degree was more pronounced in children that required treatment, which might have influenced our results.

Abstract
AIM To report an uncommon case of aneurysmal type 1 neovascularization (polypoidal choroidal vasculopathy) secondary to high-myopic staphyloma in a Caucasian patient, assessed with multimodal imaging including swept source OCT-Angiography. METHODS Observational case report. RESULTS About 73-year-old Caucasian male patient with high myopia (axial length = 27.24 mm). Fundus examination showed a myopic conus and a deep orange-brownish nodular lesion at the edge of a deep haemorrhage and connected to a large choroidal vessel. ICGA showed a circular hyperfluorescent lesion in mid-phase, without any branching vascular network. OCT-Angiography could detect the aneurysmal lesion non-invasively as a small circular high-flow lesion in the outer retina slab, with a shadowing in the choriocapillaris slab. At the level of the aneurysmal lesion, structural OCT showed a high bilobed PED, without any subretinal fluid. A vascular flow was noted within the PED on cross-sectional OCT-A, confirming the vascular aneurysmal nature of this lesion. Additionally, swept source OCT highlighted the presence of an abrupt change in choroidal thickness, from 62 µm in the peripapillary area to 120 µm underneath the polypoidal lesion, with dilated choroidal vessels. CONCLUSION To our knowledge, this is the first report of OCT-A findings in aneurysmal (polypoidal) dilation secondary to high-myopic staphyloma. We could demonstrate the usefulness of OCT-A detecting non-invasively the aneurysmal dilation and the usefulness of swept source OCT assessing the choroidal structure to better understand the pathophysiology of this uncommon finding.

Abstract
INTRODUCTION To evaluate the effects of the Navilas system guided by optical coherence tomography angiography for advanced macular neovascularization (MNV) secondary to age-related macular degeneration (AMD). METHODS Prospective case-series including nine eyes presenting with advanced MNV with persistence of exudative signs, no longer responding to anti-VEGF therapy, best-corrected visual acuity at least of 1.3 logMar. All patients were treated with Navilas guided by overlaid optical coherence tomography angiography (OCTA) images at the site of branching large neovascular trunks. RESULTS Occlusion of large neovascular trunks successfully occurred in all nine included patients. OCTA analysis revealed, at 1 month follow up, MNV total area decreasing from 6.2 ± 3.1 to 2.6 ± 3.4 mm2. At 6 months follow up, mean MNV area was 3.3 ± 3.4 mm2 (p = 0.008). CONCLUSION This preliminary study showed that Navilas treatment guided by OCTA may represent an attractive therapeutic option in advanced neovascular lesions secondary to AMD.

Abstract
PURPOSE To evaluate the risk of active choroidal neovascularization (CNV) in presence of deep irregular vascular network (IVN) in eyes with angioid streaks (AS). METHODS Observational case series including three treatment-naive eyes with angioid streaks and IVN, without CNV. Patients were followed-up during 18 months with multimodal imaging including structural optical coherence tomography (OCT) and OCT Angiography (OCT-A) to detect possible neovascular complication. RESULTS On OCT-A, IVN was detected as a peripapillary and/or macular high-flow lesion, filling the spaces between the angioid streaks in the outer retina slab. Repeated OCT-A could detect an active CNV emerging from the IVN, as a high-flow rich anastomotic vascular network with a perilesional dark halo. Patient was treated with intravitreal injections of Bevacizumab on a Pro Re Nata regimen, with a decreased CNV area and lower vascular density on control OCT-A. CONCLUSION OCT-A shown to be helpful in detecting the presence of IVN in asymptomatic eyes with AS during a routine examination. In our series, the IVN seems to be predictor of active CNV, needing a close surveillance and frequent follow-up to allow early treatment upon CNV activation.

Abstract
PURPOSE To report a case of vascularized idiopathic epiretinal membrane including the multimodal imaging. METHODS Findings on clinical examination, color fundus photography, spectral-domain optical coherence tomography, optical coherence tomography angiography, and fluorescein angiography. RESULTS Sixty-three-year-old woman with a previous rhegmatogenous retinal detachment (RRD) who presented with an asymptomatic idiopathic neovascular complex below an epiretinal membrane. It was assessed with fluorescein angiography, OCT and OCT-A. The vascularized ERM was already present previously to the retinal detachment. CONCLUSION Our case report describes an example of idiopathic epiretinal membrane complicated by neovascularization; we hypothesized hypertension could be one of the factors in this case, as it may lead to decreased retinal perfusion and upregulation in vascular endothelial growth factor (VEGF). Multimodal imaging can help in detecting neovascularized ERM.

Abstract
BACKGROUND In non-arteritic anterior ischemic optic neuropathy (NAION), optical coherence tomography angiography (OCTA) shows changes in peripapillary vascularization. However, the presence of an optic disc edema may induce artifacts that prevent visualizing the peripapillary network. The aim of this study was to evaluate the peripapillary vascularization in acute NAION using swept-source OCTA algorithms allowing segmenting only the retinal nerve fiber layer (RNFL). METHODS Retrospective analysis of 15 eyes with acute NAION of 15 patients. The optic nerve head was imaged using swept-source OCTA. Morphological and quantitative analyzes were performed. The capillary flux index (CFI), defined as the total weighted area of perfused vasculature per unit area, and the capillary perfusion density (CPD), defined as the total area of perfused microvasculature per unit area, were quantified. Each NAION eye was compared to the unaffected fellow eye using a Wilcoxon test for matched samples. RESULTS After segmentation at the RNFL, the morphological analysis showed less vascular dropout and more vascular tortuosity than the analysis of a larger segmentation. The quantitative analysis showed that the mean CFI and the CFI in the four quadrants were significantly higher in NAION eyes compared to healthy eyes (p = 0.0002 and p < 0.01). The mean CPD and the CFD in the inferior quadrant were lower in NAION eyes (p = 0.03 and p = 0.0054, respectively). DISCUSSION The RNFL segmentation allowed better visualizing the peripapillary network because the edema related darkening was reduced. The increased CFI suggests an autoregulatory phenomenon to compensate the ischemic process at the ciliary vasculature.

Abstract
INTRODUCTION To report the first case of a serpiginous choroiditis presenting after SARS-CoV-2 infection in a previously healthy young woman. CASE DESCRIPTION A 41-year-old woman reported blurry vision OS 1 month after a mild SARS-CoV-2 infection. Left eye fundus examination revealed multiple peripapillary atrophic lesions, adjacent to a larger diffuse, ill-defined, yellow-whitish deep amoeboid-like patch, involving the peripapillary region and extending temporally to the fovea. Multimodal imaging including fluorescein angiography, indocyanine-green angiography, fundus autofluorescence and optical coherence tomography was consistent with serpiginous choroiditis. A complete systemic work-up was performed to exclude potential infectious or inflammatory etiologies. The active choroidal lesions responded to high dose corticosteroids, with functional improvement. Immunomodulatory therapy with methotrexate was initiated for long-term management. CONCLUSION Serpiginous choroiditis is a rare but important sight-threatening condition that has been previously associated to viral infections, which seem to have a role in the induction and/or perpetuation of choroidal inflammation. SARS-CoV-2 infection appears to have played a role as a possible trigger for intraocular inflammation in this case. Therefore, COVID-19 patients reporting visual symptoms should be carefully evaluated in order to obtain adequate ophthalmological management to avoid irreversible visual damage.

Abstract
PURPOSE To compare the clinical findings and outcomes of vitrectomy for lamellar macular holes (LMH) versus epiretinal membrane foveoschisis (ERMF). MATERIALS AND METHODS This retrospective study enrolled 36 eyes of 35 patients with a minimum follow-up of 6 months. Spectral domain optical coherence tomography (SD-OCT) parameters and best-corrected visual acuity (BCVA) were analyzed preoperatively and postoperatively. RESULTS The 19 (52.8%) ERMF and 17 (47.2%) LMH were included. Preoperatively, eyes with LMH were characterized by a lower central foveal thickness (CFT) (102.18 ± 31.44 µm vs 159.37 ± 25.25 µm, p < 0.001) and a greater incidence of outer retinal disruption (p < 0.001). Primary anatomical success was achieved in 34/36 eyes (94.4%). Preoperative BCVA was better in ERMF (0.16 - IQR 0.09 - logarithm of the minimal angle of resolution (LogMAR) - 20/28 Snellen) than LMH (0.40 - IQR 0.30 - LogMAR, 20/50 Snellen) (p = 0.008). At 6 months after surgery, BCVA significantly improved in the ERMF group (p < 0.001), but showed insignificant change in LMH (p = 0.125). Two cases, both in the LMH group, developed full thickness macular hole after surgery. CONCLUSION Eyes with LMH showed visual stabilization after surgery, whereas the eyes in the ERMF group were susceptible to functional improvement. These differences in BCVA outcomes may be the consequence of a higher damage in the outer retina in the LMH group; an accurate SD-OCT examination is a fundamental step when deciding to proceed or not to the surgery.

Abstract
PURPOSE To evaluate the rarity, clinical features and management of Coats disease characterized by fovea-sparing enhancing the importance of pediatric retinal screening and early management to maintain a good visual acuity. METHODS Retrospective analysis of approximately 40 patients affected by Coats disease between 2000 and 2020 at the Retinoblastoma Referral Center and Ophthalmology unit of the University of Siena in Italy. RESULTS Two patients with fovea sparing Coats disease were included. Both presented an extrafoveal Coats disease (stage 2A by Shields classification) when they were 5 and 6 years old respectively.They had no anterior findings and a presenting visual acuity of 20/20 reflecting the early stage and a milder phenotype of the disease which are indeed more likely to be found in patients older than 3 years at presentation.Both presented telangiectasia and retinal exudation in the affected eye. Standard Argon laser photocoagulation and subsequently Cryotherapy were performed in the telangiectatic retinal periphery of both patients obtaining an excellent control and regression of the disease. CONCLUSIONS Careful pediatric retinal screening and early management are crucial to ensure a good visual prognosis in such an early feature of Coats disease as fovea sparing since this condition unfortunately tends to recall the physician's attention in more advanced stages.Due to the extremely poor number of articles regarding such a rare feature of Coats disease like fovea sparing, we report our experience.

Abstract
AIM To validate mobile-based funduscope for diabetic retinopathy screening in Estonia. METHODS Quality validation comparison of HEINE® iC2 funduscope and Zeiss Visucam camera with image scoring and diagnostic test accuracy measurement by sensitivity and specificity. Study took place from January 2020 until March 2020 in East-Tallinn Central Hospital's eye clinic. RESULTS Based on 90 patients, the Zeiss Visucam showed 35.6% DR prevalence while iC2 had 18.9% for images and 17.8% for videos. The average Likert score was 4.7 for Zeiss Visucam and 2.4 for both iC2 images and iC2 videos. The sensitivity of iC2 images was 72.7% (95%CI 49.6-88.4) for grader 1 and 61.9% (95%CI 38.7-81.0) for grader 2, iC2 video sensitivity was 57.1% (95%CI 37.4-75.0) and 65.4% (95%CI 44.4-82.1), respectively. The grader-based specificity for iC2 images was 96.7% (95%CI 80.9-99.8) and 93.5% (95%CI 77.2-98.9). iC2 videos had a 100% (95%CI 91.7-1.0; 92.0-1.0) specificity by both graders. Cohen's kappa agreement was 0.82 and 0.96 for images and videos. CONCLUSION Mobile-based funduscope iC2 is not valid for DR screening with non-dilated pupils and thus not suitable for clinics that do not have experienced specialist present. Moreover, the screening specialist needs to be experienced fundus photographer with extra multiple day training for funduscope use. As main resolution, mobile-based funduscope was not validated for DR screening in Estonia based on pre-set study criteria. Additional research and development of funduscope algorithm for image stripping from videos is needed for validation as iC2 benefits do not offset the gold standard at the moment.

Abstract
PURPOSE To describe clinical findings through ultra-wide field (UWF) images and optical coherence tomography angiography (OCT-A), in Susac's syndrome (SS). METHODS SS patients were retrospectively analyzed in a single center. Clinical features, ultra-wide-field retinographies (UWF-PR), UWF fluorescein angiographies (UWF-FA), and optical coherence tomography angiography & en face (OCT-A/EF) were reviewed. RESULTS Twelve eyes from six patients with a mean follow-up of 35.66 months ± SD 36.88 were included. UWF-PR showed areas of retinal whitening and cotton-wool spots in all the eyes after acute attack. Segmentary mid peripheral arteriolitis could be observed in five eyes by UWF-FA in acute and convalescent stages. OCT-A revealed capillary density changes in all of the affected eyes. During the acute phase there was a well-preserved superficial capillary network, while deep retinal plexus showed a lower density in the affected areas. OCT-A/EF revealed deep retinal plexus drop-out and surrounding edematous retina in acute attacks, becoming atrophic over time. Conversely, superficial plexus was much less affected. Perifoveal reperfusion was seen in seven eyes after the acute attack. CONCLUSIONS UWF-PR/FA and OCT-A/EF might be helpful to stablish an early diagnosis and to monitor SS progression.

Abstract
Within the COVID-19 pandemic context, the WHO has proposed a list of medicines to treat patients with severe acute respiratory syndrome (SARS-CoV-2). An analysis of their ocular side effects was performed. Only chloroquine and hydroxychloroquine were found to have an ocular impact in the medium and long-term. Detailed search strategies were performed in EMBASE, MEDLINE, SCOPUS and WOS Core Collection. Additionally, the worldwide ongoing clinical trials including chloroquine or hydroxychloroquine were evaluated, and their proposals of drug administration and exclusion criteria analyzed. In general, high maximum cumulative doses of chloroquine or hydroxychloroquine are being used for a short period in 135 currently underway clinical trials (to 21st April 2020). Typically, the doses were 2 to 5 times greater than the AAO recommendation (adjusted to weight) to avoid toxic retinopathy, the most undesirable ocular side effect. Maximum cumulative doses up to 12,000 mg for chloroquine and 18,000 mg for hydroxychloroquine were found. In prophylaxis clinical trials, 72,000 mg and 22,500 mg were the maximum cumulative doses for hydroxychloroquine and chloroquine respectively. Only 48% of the clinical trials considered retinal impairment as an exclusion criterion, and just one referred to an ophthalmic examination previous to study inclusion. How chloroquine and hydroxychloroquine treatment affect patients with a previous retinal condition is still poorly understood. A comprehensive ophthalmological examination 6 months after treatment is recommended in this subgroup. This review provides an overview of this topic and sheds light on the challenges visual caregivers may face regarding these repurposed drugs.

Abstract
In the last months, a rapidly increasing number of people have been infected with severe acute respiratory syndrome coronavirus 2, the virus causing coronavirus disease 2019 (COVID-19). Due to the risk of cross-infections, the number of visits and injections was dramatically reduced in the last months, and the time between visits has been rescheduled from every 15 to 45 min, significantly impairing the total number of available visits. Although continuity of care has been allowed, a series of measures to diminish the risk of contamination need to be adopted until the end of this pandemic outbreak, which may persist until the development of an effective vaccine. For these reasons, we have introduced a new treatment regimen that is aimed at reducing the number of in-person visits and achieving continuity of treatment. This regimen is named "Triple and Plan" (TriPla). The main advantage of the TriPla regimen is to reduce the number of visits of patients in comparison to the pro re nata and treat and extend regimen. Using the TriPla regimen, the risk of contamination would be reduced. Furthermore, by reducing the number of scheduled visits, physicians could guarantee an adequate number of examinations for each patient, lengthening the interval between visits, and reducing the risk of cross-infections.

Abstract
PURPOSE Our aim was to analyse the clinical effect of intravitreal bevacizumab treatment for macular oedema due to central/branch retinal vein occlusion (CRVO/BRVO). The end points were final best-corrected visual acuity (BCVA), BCVA improvement, final central 1-mm macular subfield thickness (CST) and change in CST. METHODS Our study included 34 CRVO and 25 BRVO patients. Patients received intravitreal bevacizumab (IVB) treatment at our department. Our control group consisted of 50 CRVO and 30 BRVO patients, who had not received this treatment because their disease developed before the anti-VEGF treatment became available. For statistical analysis, two-sample t-test, Pearson's correlation, and ANOVA were used. The level of significance was defined at p < 0.05. RESULTS With the two-sample t-test we found significant improvement of BCVA in the IVB-treated group (CRVO: 0.171 ± 0.270, p1 = 3.25×10-4; BRVO: 0.215 ± 0.282, p2 = 5.52×10-4). The difference in BCVA improvement was also significant compared to the control group (CRVO: p1 = 3.46×10-4; BRVO: p2 = 0.003). Significant decrease was observed in the CST in the treated group (CRVO: -345.114 ± 280.577, p1 = 6.94×10-9; BRVO: -151.875 ± 174.341, p2 = 1.67×10-4). In case of BRVO patients the final BCVA was significantly better in the treated group (0.617 ± 0.334) compared to the control group (0.406 ± 0.357), p = 0.016. CONCLUSION IVB treatment results in significantly better final visual acuity and leads to significantly increased BCVA improvement compared to patients with RVO-induced macular oedema receiving no treatment.

Abstract
PURPOSE To investigate the alterations in the retinal pigment epithelium (RPE) in the crest and trough portions of chorioretinal folds (CRFs) induced by an orbital vascular tumor. METHODS Review of multimodal imaging in two eyes of two patients with globe compression and CRFs from an orbital vascular tumor. RESULTS Fundus photography demonstrated obliquely extending CRFs with alternating hyperpigmented and hypopigmented linear alterations in both eyes. Fundus autofluorescence (AF) imaging showed obliquely oriented hypoAF lines, incompletely alternating with hyperAF lines. In Case 1, the hyperAF lines had interspersed hypoAF segments and Case 2 had peripapillary mottling of AF. Fluorescein angiography (FA) showed alternating hyper and hypofluorescent lines in the late phase in Case 1. Optical coherence tomography (OCT) documented relative thinning of RPE at the folded crests in Case 1 and preservation of RPE in Case 2. Swept-source OCT angiography (SS-OCTA) demonstrated oblique hyporeflective lines in the outer retina and choriocapillaris layers in Case 2. These findings suggest that the crest of a CRF represents thinned or rarified RPE with hypoAF, transmission hyperfluorescence (FA), partially attenuated RPE layer (OCT), and isoreflectivity (SS-OCTA) while the trough represents compressed RPE with irregular hyperAF, transmission hypofluorescence (FA), thickened RPE layer (OCT), and hyporeflectivity (SS-OCTA). CONCLUSION The anatomic and functional status of the RPE in CRFs based on multimodal imaging reveals normal to attenuated RPE with hypofunctionality at the fold crest and compacted, thickened RPE at the trough with segmental functional impairment on AF imaging. Anatomic information regarding CRFs is evident on OCT, FA, and SS-OCTA while the functional status is depicted on AF.

Abstract
PURPOSE To examine optic nerve head (ONH) anatomy in young adults with central retinal vein occlusion (CRVO), branch retinal vein occlusion (BRVO), central retinal artery occlusion (CRAO), branch retinal artery occlusion (BRAO) or nonarteritic anterior ischemic optic neuropathy (NA-AION) in order to look for associated, potentially predisposing anomalies. METHODS Cross-sectional study including 54 patients (ages 16-50 years) diagnosed from 2009 to 2018 with CRVO, BRVO, CRAO, BRAO, or NA-AION. Using Optical Coherence Tomography the presence of optic disc drusen (ODD), prelaminar hyperreflective lines and peripapillary hyperreflective ovoid mass-like structures (PHOMS), and determination of scleral canal size, retinal nerve fiber layer thickness (RNFLT) and macular ganglion cell layer thickness (GCLT) was obtained. Data for retinal vascular occlusion patients were grouped and analyzed together. RESULTS ODD were found in 13% of all patients, 2% of retinal vascular occlusion patients and 67% of NA-AION patients (p < 0.0001). Prelaminar hyperreflective lines were found in 35% of all patients, 24% of retinal vascular occlusion patients and 89% of NA-AION patients (p = 0.0005). PHOMS were found in 20% of all patients, 13% of retinal vascular occlusion patients and 56% of NA-AION patients (p = 0.012). RNFLT was decreased in ODD patients compared to patients without ODD (p = 0.01). Scleral canal diameter and GCLT was not correlated with ODD, prelaminar hyperreflective lines or PHOMS. CONCLUSION ODD, prelaminar hyperreflective lines and PHOMS were more frequent in NA-AION patients compared to retinal vascular occlusion patients. The prevalence of ODD in retinal vascular occlusion patients was similar to the reported prevalence in the general population.

Abstract
PURPOSE To investigate optic nerve head (ONH) microvascular changes secondary to transsynaptic retrograde degeneration (TRD), comperatively with direct retrograde degeneration and healthy controls. METHODS Patients with hemianopia due to intracranial lesion included in the study. Intracranial lesion was categorized by location: postgeniculate (causing TRD), chiasmal (causing direct retrograde degeneration). For the postgeniculate lesions, the eye on the same side of the lesion was defined as the ipsilateral eye and the eye on the opposite side as the contralateral eye. Optic disc microvasculature was evaluated with the help of optic coherence tomography angiography. RESULTS Sixteen eyes of 16 patients with chiasmal lesion, 28 eyes of 14 patients with postgeniculate lesion, and 30 eyes of 30 healthy subjects were included in the study. Ipsilateral eyes of the patients with postgeniculate lesion had decreased vessel density at the temporal sectors compatible with the affected nasal side of the visual field. Contralateral eyes showed no reduction of the vessel density at the affected nasal sectors. The eyes with chiasmal lesions had decreased vessel density at the peripapillary region and nasal half of the ONH compatible with temporal hemianopia. Vascular changes in the chiasmal lesion were more prominent than those of the postgeniculate lesion. Retinal nerve fiber layer and ganglion cell complex thickness were reduced. CONCLUSION Vessel density of ONH was reduced in patients with homonymous hemianopia, providing evidence for TRD secondary to acquired postgeniculate lesion. Direct retrograde degeneration was more prominent in affected sectors when compared to TRD.

Abstract
BACKGROUND Numerous fast threshold strategies have been developed in perimetry which use maximum likelihood approaches to estimate the threshold. A recent approach to threshold estimation has been developed estimating the threshold from a limited number of test points which further reduces examination time. This strategy, SPARK, has not been compared to the SITA strategy. The aim of this study was to compare SPARK with SITA in a normal cohort to evaluate within and between strategy agreement in threshold estimates. METHODS A total of 83 normal subjects each underwent two visual field examinations with SITA and SPARK on two separate occasions on a randomly selected eye. The eye examined and the order of strategy examined first was randomised but remained constant over the two perimetry visits. RESULTS Visual field examination with SPARK Precision was on average 33% faster than SITA Standard. A positive correlation between group mean sensitivities of SITA Standard and SPARK Precision (rho = 0.713, p < 0.001) was found. In total, 95% of stimulus locations were located within the 95% limits of agreement and linear regression on the differences in sensitivities showed no statistically significant proportional bias (t = 1.713, p = 0.09). Pointwise analysis showed SITA Standard had significantly larger variability for individual stimulus locations examined over two visits when compared to SPARK (t = 9.175, p < 0.001). CONCLUSION The clinical examination of SPARK yields a sensitivity profile similar to SITA but in a faster examination time. The lower threshold variability of SPARK may be as a result of data smoothing in the threshold estimation process.

Abstract
PURPOSE To investigate whether qualitative and quantitative features of choroidal neovascular membranes are associated with anti-vascular endothelial growth factor treatment response in patients with neovascular age-related macular degeneration. METHODS A total of 41 eyes were included in this cross-sectional observational study and divided into "good responders" and "poor responders" based on the long-term functional changes, frequency of recurrent choroidal neovascular activity, and injection need. Enface optical coherence tomography angiography images were obtained and qualitative features of choroidal neovascular membranes were described based on vessel network density. Then, quantitative measurements including vessel area, vessel length, junction density, and lacunarity were calculated using validated software (ImageJ and AngioTool). Chi-square tests, t-test, or Mann-Whitney U tests were used for group comparisons, and intraclass correlation coefficients were calculated for reliability assessment of quantitative analyses. RESULTS Twenty-two eyes treated by a median of 9 (3-24) anti-vascular endothelial growth factor injections at a median follow-up of 41 (12-89) months were categorized as good responders, 19 treated by a median of 26 (11-46) injections at a median follow-up of 44.5 (12-84) months as poor responders. Good responder group mostly had loose network (45.5%), and poor responders mostly had dense network (47.7%). The difference was not statistically significant (p = 0.25). The size of the lesion was 2.7 times greater at baseline (p = 0.04) and 1.7 times greater at final examination in the poor responder group (p = 0.04). Lacunarity index, showing lesion heterogeneity, was higher in good responders (p = 0.018) than poor responders. Other quantitative vascular features did not significantly differ between the groups (p > 0.05). CONCLUSION Long-term remodeling of chronically treated choroidal neovascular may be non-invasively and reproducibly investigated using optical coherence tomography angiography. Quantitative analysis and lacunarity index, in particular, may be used as a measure of vessel maturation and guide treatment strategies in neovascular age-related macular degeneration.

Abstract
OBJECTIVE To evaluate foveal thickness, foveal microvasculature, and refractive error in children with asymmetric involvement of retinopathy of prematurity who had laser treatment in one eye and spontaneously regressed retinopathy of prematurity in the fellow eye. METHODS Totally, 17 children (34 eyes) with a history of asymmetric course of acute Zone II retinopathy of prematurity were assessed. Data on best-corrected visual acuity, refractive status, axial length, anterior chamber depth, and optical coherence tomography angiography findings were analyzed between treated and non-treated fellow eyes. RESULTS Treated eyes were more myopic than non-treated eyes (mean, -0.09 ± 1.86 diopters vs mean, 0.07 ± 0.98 diopters, p = 0.026). Compared to non-treated eyes, treated eyes had shallower anterior chamber depth (mean, 3.27 ± 0.24 mm vs mean, 3.55 ± 0.19 mm, p = 0.02). No significant difference was observed regarding optical coherence tomography angiography parameters between two eyes of the children. The mean central foveal thickness was found to be higher in treated eyes than in non-treated eyes (297.46 ± 22.03 vs 275.55 ± 18.45, p = 0.009). Higher number of laser spots were associated with decreased parafoveal superficial capillary plexus vessel density (r = -0.56, p = 0.02) and increased central foveal thickness (r = 0.62, p = 0.008). CONCLUSION Our results revealed no difference in optical coherence tomography angiography parameters between laser-treated and non-treated eyes in children with asymmetric involvement of Zone II retinopathy of prematurity except for a higher central foveal thickness in laser-treated eyes. Treated eyes were more myopic than the non-treated eyes. Number of laser applications during treatment had an impact on parafoveal superficial capillary plexus vessel density.
