RESUMO
In this article, we present three cases diagnosed with active choroidal neovascularization (CNV): two cases diagnosed with neovascular age-related macular degeneration (nAMD), and one case with myopic CNV in an elderly eye that presented a characteristic and unique optical coherence tomography (OCT) sign consisting of well-defined, circular-shaped multiple concentric layers of alternating iso-hyperreflective material located between the external limiting membrane and outer photoreceptor layers, which seems to be a multilayered bacillary layer detachment (BALAD). Multilayered exudative BALAD in active CNV may be a new and characteristic OCT sign. [Ophthalmic Surg Lasers Imaging Retina 2024;55:92-94.].

PURPOSE: To describe the incidence, features, and clinical outcomes of photodynamic therapy-induced acute exudative maculopathy (PAEM) in circumscribed choroidal hemangioma. METHODS: Prospective series of 10 patients who underwent standard-fluence photodynamic therapy for circumscribed choroidal hemangioma. Best-corrected visual acuity in the Early Treatment Diabetic Retinopathy Score and swept-source optical coherence tomography were performed before PDT and 3 days and 1 month after PDT. Central retinal thickness, circumscribed choroidal hemangioma retinal thickness, and subretinal fluid were measured. Photodynamic therapy-induced acute exudative maculopathy was considered as an increase ≥50 µ m in subretinal fluid or intraretinal fluid or the appearance of fibrin 3 days after photodynamic therapy. RESULTS: Six men and four women were included; median age was 55 years (19-69 years). The incidence rate of PAEM was 7 of 10. Five PAEM patients showed an increase in intraretinal fluid, two in subretinal fluid, and one developed abundant fibrin. Median best-corrected visual acuity at baseline was 57.5 letters (5-76 letters) being stable at 1 month (64 letters; 5-80) ( P = 0.03). Median central retinal thickness increased from 516 µ m (262-1,265 µ m) to 664.5 µ m after 3 days and diminished to 245 µ m after 1 month (156-1,363) ( P ≤ 0.022). In 6 of 7 of PAEM, a complete resolution of the fluid was obtained. CONCLUSION: Photodynamic therapy-induced acute exudative maculopathy was frequent in circumscribed choroidal hemangioma, although a favorable prognosis was observed in most cases.

PURPOSE: To investigate best corrected visual acuity (BCVA), subretinal fluid (SRF) absorption time or ellipsoid zone (EZ) restoration time and various variables in patients with persistent SRF after successful primary repair of rhegmatogenous retinal detachment (RRD). METHODS: This retrospective multicenter study allowed independent analysis of the healing pattern by two observers based on composite of serial cross-sectional macular optical coherence tomography (OCT) scans. Univariate and multivariate analyses were implemented. RESULTS: One hundred and three cases had persistent SRF after pars plana vitrectomy, scleral buckling, or pneumatic retinopexy. By univariate analysis, SRF resolution time correlated positively with the number of retinal breaks (p < 0.001) and with increased myopia (p = 0.011). Using multivariate analysis, final BCVA (log MAR) correlated positively with age, duration of RRD, initial BCVA (OR = 3.28; [95%CI = 1.44-7.47]; p = 0.015), and SRF resolution time (OR = 0.46 [95%CI 0.21-1.05]; p = 0.049). EZ restoration time was longer with increasing number of retinal tears (OR = 0.67; [95%CI 0.29-1.52]; p = 0.030), worse final BCVA, and presence of macula-off RRD (OR = 0.26; [95%CI 0.08-0.88]; p = 0.056). SRF resolution time correlated marginally with prone position. CONCLUSIONS: Residual posterior SRF is more common in eyes with multiple breaks or in myopic eyes. Final BCVA is better in younger subjects and in eyes with shorter duration of RRD. Persistent SRF is a self-limited disorder with a mean resolution of 11.2 months with good visual prognosis improving from a mean baseline logMAR of 1.08 to 0.25 at one year.

RESUMO
PURPOSE: To analyze the 2-year clinical outcomes after photodynamic therapy-induced acute exudative maculopathy (PAEM) in patients with chronic central serous chorioretinopathy. METHODS: Prospective observational study that included 64 eyes of 64 patients with chronic central serous chorioretinopathy who received half-fluence photodynamic therapy and had a 2-year follow-up. Patients were classified into two groups based on whether they had had PAEM at 3 days after treatment (PAEM+, n = 22; ≥50 µ m) increase in subretinal fluid or not (PAEM-, n = 42). Best-corrected visual acuity and subretinal fluid changes evaluated with optical coherence tomography were registered at 3 days, 1 month, 3 months, 1 year, and 2 years after photodynamic therapy. The number of recurrences, the appearance of outer retinal atrophy, and choroidal neovascularization were analyzed. RESULTS: Best-corrected visual acuity was 75.9 ± 13.6 (20/32) and 82.0 ± 11.0 letters (20/25) at 2 years in the PAEM+ and PAEM- groups, respectively ( P = 0.055). There were no differences in the best-corrected visual acuity change (4.2 ± 7.7 vs. 3.3 ± 7.1 letters; P = 0.654) and the subretinal fluid decrease (-117.3 ± 74.2 vs. -138.5 ± 83.6 µ m; P = 0.323) at 2 years between patients with and without PAEM. No differences in the number of recurrences ( P = 0.267), the appearance of choroidal neovascularization ( P = 0.155), or outer retinal atrophy ( P = 0.273) between both groups were noted. CONCLUSION: Patients with chronic central serous chorioretinopathy with and without PAEM presented similar results at 2 years in best-corrected visual acuity gain, subretinal fluid reduction, and complication rate.

BACKGROUND: To describe the functional and anatomical impact that the worldwide shortage of verteporfin has had on patients diagnosed with chronic central serous chorioretinopathy (cCSCR) whose treatment with photodynamic therapy (PDT) had to be delayed. METHODS: Prospective observational study. Patients were divided into two groups based on the time interval since PDT had been indicated: groups 1 and 2, with waiting times of less and more than 9 months respectively. Best corrected visual acuity (BCVA), the maximum height of the subretinal fluid (MSRF) and subfoveal choroidal thickness (SFCT) at the baseline visit and the last visit were compared. RESULTS: 49 eyes of 48 patients with cCSCR were included. The mean waiting time for PDT was 9.0 ±3.8 months. The mean BCVA was 69.0 ±17.1 letters and 68.9 ±16.4 letters for the baseline and last visit respectively, showing no difference (p= 0.958). Although there was no difference in the mean global BCVA, 15 eyes (30.5%) showed a deterioration of ≥5 letters, including 7 eyes (14%) with a decrease of ≥10 letters. Mean MSRF height was 151.4 ±97.2 µm and 98.2 ±83.1 µm for the baseline and last visit respectively (p= 0.005), persisting in 74.5% of the eyes. CONCLUSION: No significant impact was observed in the BCVA in cCSCR due to the shortage of verteporfin. However, one-third of patients had BCVA loss. There was a significant spontaneous decrease in MSRF, but it persisted in the majority of the patients, still susceptible to PDT.

PURPOSE: To assess the presence of macular intervortex venous anastomosis in central serous chorioretinopathy (CSCR) patients using en face optical coherence tomography (EF-OCT). METHODS: A cross-sectional study where EF-OCT 6 × 6 and 12 × 12 mm macular scans of patients with unilateral chronic CSCR were evaluated for anastomosis between vortex vein systems in the central macula. The presence of prominent anastomoses was defined as a connection with a diameter ≥150 µm between the inferotemporal and superotemporal vortex vein systems which crossed the temporal raphe. Three groups were studied: CSCR eyes (with an active disease with the presence of neurosensorial detachment; n = 135), fellow unaffected eyes (n = 135), and healthy eyes as controls (n = 110). Asymmetries, abrupt termination, sausaging, bulbosities and corkscrew appearance were also assessed. RESULTS: In 79.2% of the CSCR eyes there were prominent anastomoses in the central macula between the inferotemporal and superotemporal vortex vein systems, being more frequent than in fellow eyes and controls (51.8% and 58.2% respectively). The number of anastomotic connections was higher in the affected eye group (2.9 ± 1.8) than in the unaffected fellow eye group (2.1 ± 1.7) and the controls (1.5 ± 1.6) (p < 0.001). Asymmetry, abrupt terminations and the corkscrew appearance of the choroidal vessels were more frequent in the affected eyes, although no differences in sausaging or bulbosities were observed. CONCLUSIONS: Intervortex venous anastomoses in the macula were common in CSCR, being more frequently observed in affected eyes than in fellow unaffected eyes and healthy controls. This anatomical variation could have important implications concerning the pathogenesis and classification of the disease.
RESUMO
OBJECTIVE: To evaluate the impact of subfoveal choroidal thickness (SFCT) and other clinical biomarkers in intravitreal anti-vascular endothelial growth factor response in treatment-naive Caucasian patients diagnosed with polypoidal choroidal vasculopathy (PCV/AT1). DESIGN: Cross-sectional study. PARTICIPANTS: Treatment-naive patients diagnosed with PCV/AT1 recruited in a single centre from January 2013 to December 2020. METHODS: Eligibility was determined in treatment-naive PCV patients who received a loading dose of 3 injections of 0.5 mg ranibizumab. A diagnosis of PCV/AT1 was made based on the diagnostic criteria in the efficacy and safety of verteporfin photodynamic therapy in combination with ranibizumab or alone versus ranibizumab monotherapy in patients with sumptomatic macular polypoidal choroidal vasculopathy study. Choroidal thickness was manually measured by enhanced depth imaging technology in Spectralis spectral domain optical coherence tomography. RESULTS: Eighty-three eyes of 83 patients were included in this study, 47 patients diagnosed with PCV/AT1 with a good response to 3 intravitreal injections of ranibizumab and 36 with a poor response. The receiver operating characteristic curve of treatment effect against the SFCT revealed that the area under the curve was 0.85 (range, 0.74-0.96). Based on the Youden index, the optimal SFCT cut-off point for predicting a poor response to anti-vascular endothelial growth factor is 257 µm. In the multivariate analysis, the SFCT remained statistically significant (odds ratio 1.02 [range, 1.01-1.04]; P = 0.008). The combined effect of treatment effect against clinical biomarkers produced an area under the curve of 0.90 (range, 0.82-0.98). CONCLUSION: SFCT is a risk factor for a poor response to the 3 loading injections of ranibizumab in treatment-naive PCV/AT1 Caucasian patients. A cut-off point of 257 µm could be a valuable parameter for defining the population at risk for an inadequate response to ranibizumab.

PURPOSE: To assess the repeatability of flow signal voids (FSV) measurements of the choriocapillaris (CC) and choroid (CH) in central serous chorioretinopathy (CSCR) by Swept-Source optical coherence tomography angiography (SS-OCTA). METHODS: Cross-sectional study including 104 eyes of 52 patients with unilateral CSCR. Two consecutive macular 6x6 mm SS-OCTA scans (Plex Elite 9000; Zeiss, Dublin, CA) were obtained from the affected eyes with persistent subretinal fluid (SRF) (CSCR group) and the fellow unaffected eyes (control group). FSV area and the number of contours measurements were analyzed using three slabs: inner CC, outer CC and CH. The repeatability of the measurements was assessed with intraclass correlation coefficients (ICC) and coefficients of variation (CV). RESULTS: In the CSCR group, ICCs for the FSV area in the three slabs were all ≥0.859, observing higher values for the outer CC and the CH (0.959 and 0.964) than for the inner CC (0.859). Similar ICC values were obtained for the FSV area in control eyes, observing the highest values for the outer CC (0.949), followed by the CH (0.932) and inner CC (0.844). Regarding the FSV number of contours measurements, ICCs were higher for the outer CC and CH (0.949 and 0.932) than for inner CC (0.844). CV for the FSV area was 4.7%, 3.8% and 8.6% in the CSCR eyes and 4.8%, 3.9% and 9.3% in the control group for the inner CC, outer CC and CH respectively. CONCLUSION: SS-OCTA offers good repeatability to quantify macular FSV in CSCR eyes and fellow eyes.

Consequences of the COVID-19 pandemic on medical care have been extensively analyzed. Specifically, in ophthalmology practice, patients suffering age-related macular degeneration (AMD) represent one of the most affected subgroups. After reporting the acute consequences of treatment suspension in neovascular AMD, we have now evaluated these same 242 patients (270 eyes) to assess if prior functional and anatomical situations can be restored after twelve months of regular follow-up and treatment. We compared data from visits before COVID-19 outbreak and the first visit after lockdown with data obtained in subsequent visits, until one year of follow-up was achieved. For each patient, rate of visual loss per year before COVID-19 pandemic, considered "natural history of treated AMD", was calculated. This rate of visual loss significantly increased during the lockdown period and now, after twelve months of regular follow-up, is still higher than before COVID outbreak (3.1 vs. 1.6 ETDRS letters/year, p < 0.01). Percentage of OCT images showing active disease is now lower than before the lockdown period (51% vs. 65.3%, p = 0.0017). Although anatomic deterioration, regarding signs of active disease, can be apparently fully restored, our results suggest that functional consequences of temporary anti-VEGF treatment suspension are not entirely reversible after 12 months of treatment, as BCVA remains lower and visual loss rate is still higher than before the COVID-19 pandemic.
RESUMO
PURPOSE: To assess the prediction of the response to photodynamic therapy (PDT) in chronic central serous chorioretinopathy (CSCR) based on spectral-domain optical coherence tomography (SD-OCT) images using deep learning (DL). METHODS: Retrospective study including 216 eyes of 175 patients with CSCR and persistent subretinal fluid (SRF) who underwent half-fluence PDT. SD-OCT macular examination was performed before (baseline) and 3 months after treatment. Patients were classified into groups by experts based on the response to PDT: Group 1, complete SRF resorption (n = 100); Group 2, partial SRF resorption (n = 66); and Group 3, absence of any SRF resorption (n = 50). This work proposes different computational approaches: 1st approach compares all groups; 2nd compares groups 1 vs. 2 and 3 together; 3rd compares groups 2 vs. 3. RESULTS: The mean age was 55.6 ± 10.9 years and 70.3% were males. In the first approach, the algorithm showed a precision of up to 57% to detect the response to treatment in group 1 based on the initial scan, with a mean average accuracy of 0.529 ± 0.035. In the second model, the mean accuracy was higher (0.670 ± 0.046). In the third approach, the algorithm showed a precision of 0.74 ± 0.12 to detect the response to treatment in group 2 (partial SRF resolution) and 0.69 ± 0.15 in group 3 (absence of SRF resolution). CONCLUSION: Despite the high clinical variability in the response of chronic CSCR to PDT, this DL algorithm offers an objective and promising tool to predict the response to PDT treatment in clinical practice.

BACKGROUND: The main purpose was to evaluate the changes in peripapillary retinal nerve fiber layer (RNFL) thickness and vessel density (VD) in post-COVID-19 patients during 12-month follow-up. METHODS: In this prospective study, patients with COVID-19 who were attended in the Hospital Clinico San Carlos (Madrid, Spain) were included. All patients underwent a complete ophthalmological examination, optic nerve head optical coherence tomography (OCT), and OCT angiography (OCTA) using the Cirrus HD-OCT 5,000 with AngioPlex OCTA 1, 3, and 12 months after laboratory-confirmed diagnosis. Sociodemographic data, medical history, disease severity, and laboratory workup were registered. RESULTS: A total of 180 eyes of 90 patients with SARS-CoV-2 infection were included; the mean age was 55.5 ± 8.9 years, and 46 patients (51%) were females. The mean visual acuity was 0.76 ± 0.16, and no abnormalities attributable to SARS-CoV-2 were detected in the ocular or fundus examination. No differences in the OCT and OCTA data were found between severity groups in each visit (all P > 0.05). Overall, there was a decrease in RNFL global thickness ( P < 0.001) from the first to the last visit, and an increase in VD and flux index was noted in some sectors at the 12-month examination. A significant correlation was detected at 12 months between vascularization parameters and RNFL thickness. CONCLUSIONS: One year after SARS-CoV-2 infection, changes in peripapillary RNFL thickness and vascularization occur, possibly indicating a recovery in such parameters.

PURPOSE: To assess the efficacy of an additional photodynamic therapy (PDT) in chronic central serous chorioretinopathy (cCSCR) patients who have two or more previous failed PDTs. METHODS: Ten eyes of 10 patients with cCSCR who had received two or more PDTs without complete resolution of the subretinal fluid (SRF) or with early recurrence (before 3 months) were included. An additional half-fluence PDT was performed. Swept-source optical coherence tomography (OCT) and OCT angiography were performed before, 3 days, 1 month, 3 months, 6 months and 12 months after treatment. Age, gender, best-corrected visual acuity (BCVA), subfoveal choroidal thickness, SRF and vessel occlusion in the choriocapillaris (CC) were collected. RESULTS: The median number of previous PDTs was 3 (range 2 to 4). BCVA before and 12 months after treatment was 72 letters (50 to 95) and 78 letters (55 to 100) (p=0.094). Median initial SRF was 94 µm (50 to 306), being 0 µm (range 0 to 81) at the end of the follow-up (p=0.007). After the additional PDT, 8 out of 10 patients had a complete SRF resorption. All the patients except one who had a complete response (7/8) had an occlusion in the CC 3 days after PDT. CONCLUSION: Despite previous failed PDTs in cCSCR, good anatomical results can be achieved, this being more likely if an early vessel occlusion in the CC is observed. Even when the BCVA did not improve, the high rate of fluid resolution could justify the additional PDT treatment in order to maintain visual function.

PURPOSE: To assess the early changes produced in the choriocapillaris (CC) and choroidal vasculature using swept-source optical coherence tomography angiography (SS-OCTA) in patients with persistent central serous chorioretinopathy (CSCR) as predictors of the efficacy after photodynamic therapy (PDT). METHODS: Prospective observational study in 52 eyes of 52 patients with persistent subretinal fluid (SRF). SS-OCTA scans of the 6 × 6 mm macular region were assessed before; 2-3 days, one month and three months after half-fluence PDT. Vessel occlusion in the CC and choroid was measured as flow signal voids (FSV). RESULTS: A 3.67 ± 4.12 and 2.76 ± 3.63 fold increase in CC and CH FSV, due to vessel occlusion, was observed at 2-3 days after PDT versus baseline. There was less SRF at 3 months in patients with an increase in FSV (≥1-fold) compared to those without this increase (<1-fold) after PDT (p ≤ 0.003). An association between the increase in CC and choroidal FSV at the early control (2-3 days) and the height of SRF at 1 month was found (R=-0.405; p = 0.002 and R=-0.356; p = 0.008 respectively). In a multivariate model, the SRF at one month was not associated with age, gender, visual acuity, or FSV (p ≥ 0.288). At 3 months, flow restoration was achieved in the choroid versus the baseline (p = 0.619), but there was a persistent increase in the CC FSV (p = 0.008). CONCLUSIONS: Early vessel occlusion by OCTA after PDT in CSCR was associated with good treatment response. Therefore, an increase in FSV immediately after PDT could be a biomarker to predict SRF resorption.

PURPOSE: To describe the incidence and characteristics of photodynamic therapy-induced acute exudative maculopathy (PAEM) and bacillary layer detachment in patients with chronic central serous chorioretinopathy. METHODS: This was a prospective observational case series including 92 eyes of 75 patients who underwent photodynamic therapy. Best-corrected visual acuity, optical coherence tomography, and optical coherence tomography angiography were performed before, 3 days, 1 month, and 3 months after half-fluence photodynamic therapy. Two groups were established depending on the presence or absence (N = 28 and N = 64, respectively) of PAEM. Choriocapillaris flow voids increase, subfoveal choroidal thickness, and the presence of choroidal neovascularization were collected. RESULTS: The incidence of PAEM was 28/92 (30.4%). There was no difference in the age, sex, baseline subretinal fluid, subfoveal choroidal thickness, or the presence of choroidal neovascularization between groups (P ≥ 0.094). No differences emerged in the subretinal fluid at 1 and 3 months after photodynamic therapy between groups (P ≥ 0.524), nor in the mean best-corrected visual acuity gain at 3 months (4.1 ± 7.6 vs. 3.6 ± 6.4 letters; P = 0.773). A bacillary layer detachment was observed in 13 patients with PAEM (46.4%). CONCLUSION: Photodynamic therapy-induced acute exudative maculopathy is frequent in patients with chronic central serous chorioretinopathy but has a favorable prognosis. There was no association between PAEM and age, sex, subfoveal choroidal thickness, or choroidal neovascularization; however, it was related to choriocapillaris flow voids increase.

OBJECTIVE: To investigate the optic nerve and macular parameters of children who recovered from COVID-19 compared with healthy children using optical coherence tomography (OCT). DESIGN: Cohort study. SETTING: Hospital Clinico San Carlos, Madrid. PATIENTS: Children between 6 and 18 years old who recovered from COVID-19 with laboratory-confirmed SARS-CoV-2 infection and historical controls were included. INTERVENTIONS: All patients underwent an ophthalmological examination, including macular and optic nerve OCT. Demographic data, medical history and COVID-19 symptoms were noted. MAIN OUTCOME MEASURES: Peripapillary retinal nerve fibre layer thickness, macular retinal nerve fibre layer thickness, macular ganglion cell layer thickness and retinal thickness. RESULTS: 90 patients were included: 29 children who recovered from COVID-19 and 61 controls. Patients with COVID-19 presented an increase in global peripapillary retinal nerve fibre layer thickness (mean difference 7.7; 95% CI 3.4 to 12.1), temporal superior (mean difference 11.0; 95% CI 3.3 to 18.6), temporal inferior (mean difference 15.6; 95% CI 6.5 to 24.7) and nasal (mean difference 9.8; 95% CI 2.9 to 16.7) sectors. Macular retinal nerve fibre layer analysis showed decreased thickness in the nasal outer (p=0.011) and temporal inner (p=0.036) sectors in patients with COVID-19, while macular ganglion cell layer thickness increased in these sectors (p=0.001 and p=0.015, respectively). No differences in retinal thickness were noted. CONCLUSIONS: Children with recent history of COVID-19 present significant changes in peripapillary and macular OCT analyses.

PURPOSE: To investigate the peripapillary retinal nerve fiber layer thickness (RNFLT), macular RNFLT, ganglion cell layer (GCL), and inner plexiform layer (IPL) thickness in recovered COVID-19 patients compared to controls. METHODS: Patients previously diagnosed with COVID-19 were included, while healthy patients formed the historic control group. All patients underwent an ophthalmological examination, including macular and optic nerve optical coherence tomography. In the case group, socio-demographic data, medical history, and neurological symptoms were collected. RESULTS: One hundred sixty patients were included; 90 recovered COVID-19 patients and 70 controls. COVID-19 patients presented increases in global RNFLT (mean difference 4.3; CI95% 0.8 to 7.7), nasal superior (mean difference 6.9; CI95% 0.4 to 13.4), and nasal inferior (mean difference 10.2; CI95% 2.4 to 18.1) sectors of peripapillary RNFLT. Macular RNFL showed decreases in COVID-19 patients in volume (mean difference -0.05; CI95% -0.08 to -0.02), superior inner (mean difference -1.4; CI95% -2.5 to -0.4), nasal inner (mean difference -1.1; CI95% -1.8 to -0.3), and nasal outer (mean difference -4.7; CI95% -7.0 to -2.4) quadrants. COVID-19 patients presented increased GCL thickness in volume (mean difference 0.04; CI95% 0.01 to 0.07), superior outer (mean difference 2.1; CI95% 0.8 to 3.3), nasal outer (mean difference 2.5; CI95% 1.1 to 4.0), and inferior outer (mean difference1.2; CI95% 0.1 to 2.4) quadrants. COVID-19 patients with anosmia and ageusia presented an increase in peripapillary RNFLT and macular GCL compared to patients without these symptoms. CONCLUSIONS: SARS-CoV-2 may affect the optic nerve and cause changes in the retinal layers once the infection has resolved.

PURPOSE: To evaluate retinal vascular changes in children who have recovered from coronavirus disease (COVID-19) using optical coherence tomography angiography (OCTA) and to compare the results with age-matched healthy children. METHODS: In this cross-sectional case-control study, children 6-18 years of age with laboratory-confirmed SARS-CoV-2 infection were compared with historic healthy controls. All participants underwent ophthalmological examination, including fundus photography and OCTA of the macular region and optic disk. COVID-19 children were examined 4-8 weeks after COVID-19 diagnoses. Demographic data, medical history, and COVID-19 symptoms were noted. OCTA parameters in the superficial capillary plexus (SCP) were analyzed according to ETDRS sectors and peripapillary quadrants. RESULTS: A total of 72 patients were included: 27 recovered COVID-19 children and 45 controls. Mean age for cases was 11.96 ± 3.8 years (18 females [66%]); for controls, 11.02 ± 2.0 years (29 females [64%]). Macular OCTA of the SCP showed a significant increase in retinal vessel density (VD) in recovered COVID-19 children compared with healthy controls in the inner ring (P = 0.001). Macular perfusion density (mPD) was also increased in the inner ring (P = 0.001). Peripapillary OCTA evidenced a significant higher flux index (FI) in all four quadrants (P < 0.001). CONCLUSIONS: Recovered COVID-19 children present increased retinal VD, mPD, and peripapillary FI shortly after recovery. Since the retinal vasculature is considered a unique window to assess microvascular changes, these findings may represent a potential in vivo biomarker of vascular abnormalities in COVID-19 children in other organs.

PURPOSE: To assess the anterior scleral thickness (AST) and describe the presence of a visible supraciliary space (SCS) in central serous chorioretinopathy (CSC) patients by swept-source optical coherence tomography (SS-OCT). STUDY DESIGN: Cross-sectional comparative study. MATERIAL AND METHODS: Three groups were studied: 1) 64 eyes of 54 patients with CSC with persistent subretinal fluid (SRF); 2) 42 fellow eyes of CSC patients without SRF; 3) 65 eyes of 65 controls matched by age, sex and axial length (AL). The AST was measured in the temporal and nasal quadrants at 0, 1, and 2 mm from the scleral spur by SS-OCT. The presence of a visible SCS was also assessed. RESULTS: No differences were observed in the AST0 among the three groups (p≥ 0.665). The temporal AST1 was significantly thicker in the CSC group (530.3 ±67.1 µm) than in the controls (505.5 ±73.9; p=0.041). Mean AST2 was also thicker in the CSC group and the fellow eyes both for the temporal (519.4 ±89.1 µm and 519.8 ±98.5 µm respectively) and nasal quadrants (564.2 ±124.9 µm and 570.5 ±131.0 µm) than in the controls (450.1 ±76.8 and 473.3 ±111.6 µm) (all p≤0.001). A visible SCS was detected in the eyes of 8 CSC patients, in 4 fellow eyes and only in 1 control eye. CONCLUSIONS: AST measured by SS-OCT was significantly greater in CSC eyes than in healthy eyes. Also, a visible SCS was detected in CSC eyes. Thus, thicker sclera in CSC eyes could be associated with the physiopathology of this disease.

PURPOSE: This paper aimed to present daily-practice recommendations for the management of diabetic macular edema (DME) patients based on available scientific evidence and the clinical experience of the consensus panel. METHODS: A group of Spanish retina experts agreed to discuss different aspects related with the clinical management of DME patients. RESULTS: Panel was mainly focused on therapeutic objectives in DME management; definition terms; and role of biomarkers as prognostic and predictive factors to intravitreal treatment response. The panel recommends to start DME treatment as soon as possible in those eyes with a visual acuity less than 20/25 (always according to the retina unit capacity). Naïve patient was defined, in a strict manner, as a patient who, up to that moment, had never received any treatment. A refractory DME patient may be defined as the one who did not achieve a complete resolution of the disease, regardless of the treatment administered. Different optical coherence tomography biomarkers, such as disorganization of the retinal inner layers, hyperreflective dots, and cysts, have been identified as prognostic factors. CONCLUSION: This document has sought to lay down a set of recommendations and to identify key issues that may be useful for the daily management of DME patients.
