Machairoudia G, Kazantzis D, Chatziralli I, Kampoli K, Ntavatzikos A, Theodossiadis P, Koumarianou A. Prevalence and risk factors of dry eye disease in patients treated with aromatase inhibitors for breast cancer. Clin Exp Optom 2024; 107:415-419. [PMID: 37699786 DOI: 10.1080/08164622.2023.2239247] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Revised: 07/15/2023] [Accepted: 07/18/2023] [Indexed: 09/14/2023] Open
Abstract
CLINICAL RELEVANCE Treatment with aromatase inhibitors (AIs) in patients with breast cancer can lead to dry eye disease (DED). BACKGROUND The purpose of the study is to determine the prevalence and risk factors of DED in patients treated with AIs for breast cancer. METHODS Participants in this cross-sectional study were patients with breast cancer treated with AIs. Demographic and clinical data, including age, sex, type of cancer, stage, grade, duration of treatment and adjuvant chemotherapy and/or radiotherapy were collected. All patients underwent a detailed ophthalmic examination, as well as Tear Break up Time (TBUT) and Schirmer test, while Ocular Surface Disease Index (OSDI) questionnaires were administered. Based on the clinical findings, a diagnosis of DED was made, and prevalence was calculated. Univariate analysis of the association of different variables with DED was performed. A logistic regression analysis was done to identify risk factors for DED among study population. RESULTS A total of 102 participants were included in the study. The mean age of patients was 62.4 ± 10.8 years. A total of 77 out of 102 patients (75.5%) had ductal, 16 (15.7%) lobular and 9 (8.8%) other types of breast cancer. A total of 83 patients (81.4%) received chemotherapy and 70 patients (68.6%) received radiotherapy. The mean duration of treatment was 24.4 ± 18.9 months. The prevalence of DED in the study sample was 69.6%. Patients who received radiotherapy (OR = 3.31, 95%CI = 1.30-7.82, p = 0.01) or were under treatment with AIs for more than 24 months (OR = 3.53, 95%CI = 1.47-9.21, p = 0.002) were found to have an increased risk of DED. CONCLUSION There was a high prevalence of DED among the study population. Radiotherapy and duration of treatment with AIs were independently associated with DED.

Abstract
PURPOSE To investigate changes in choroidal thickness in patients diagnosed with pseudoexfoliation syndrome (PEX) compared to healthy controls, using optical coherence tomography (OCT). METHODS PubMed and Scopus databases were systematically searched for published articles comparing choroidal thickness between patients with PEX and healthy controls. Standardized Mean Difference (SMD) with 95 % confidence interval (CI) was computed to compare continuous variables. Revman 5.4 was used for the analysis. Subgroup analyses were performed according to OCT devices used. RESULTS 12 studies were included in our analysis. Subfoveal choroidal thickness was decreased in patients with PEX compared to healthy controls. Subgroup analysis confirmed this finding in studies that used Heidelberg or Optovue OCT Devices. CONCLUSION Our meta-analysis showed that choroidal thickness was decreased in patients with PEX compared to controls. Increased heterogeneity and small case-control studies are the main limitations of the meta-analysis. Further studies are needed to evaluate the clinical significance of reduced subfoveal choroidal thickness in PEX.

Association of PON1, APOE and SDF-1 Gene Polymorphisms with Treatment Response to Intravitreal Anti-VEGF Treatment in Patients with Retinal Vein Occlusion. Semin Ophthalmol 2024; 39:201-208. [PMID: 37997789 DOI: 10.1080/08820538.2023.2283028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Accepted: 11/09/2023] [Indexed: 11/25/2023]
Abstract
PURPOSE The purpose of this study was to determine whether specific genetic polymorphisms affect the response to intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatment in patients with macular oedema secondary to retinal vein occlusion (RVO). METHODS Participants in this prospective study were 50 patients with macular oedema secondary to RVO, who were treated with intravitreal ranibizumab or aflibercept, and were followed-up for 12 months after initiation of treatment. Five single nucleotide polymorphisms (SNPs) from three different genes (APOE, PON1, SDF-1) were examined as potential predictors for treatment response to intravitreal anti-VEGF agents. RESULTS Patients with the LL genotype of the PON1 L55M SNP had significantly higher reduction in central subfield thickness (CST) at month 12 after initiation of intravitreal anti-VEGF treatment (101.63 ± 56.80 μm in LL vs. 72.44 ± 39.41 μm in LM vs. 40.25 ± 19.33 μm in MM, p = .026). Patients with the M allele of the PON1 L55M SNP were significantly associated with lower reduction in CST compared to non-carriers (68.29 ± 38.77 μm in LM + MM vs. 101.63 ± 56.80 μm in LL, p = .032). CONCLUSION PON1 L55M SNP may serve as a promising genetic biomarker for predicting response to intravitreal anti-VEGF treatment in patients with macular oedema due to RVO.

Abstract
BACKGROUND AND OBJECTIVE This study investigated changes in retinal nerve fiber layers (RNFL) in patients diagnosed with chronic obstructive pulmonary disease (COPD) compared to healthy control patients, using optical coherence tomography. METHODS PubMed, Cochrane Library, and Google Scholar databases were systematically searched for published articles comparing RNFL between patients with COPD and healthy controls. Standardized mean difference (SMD) with 95% confidence interval (CI) was computed to compare continuous variables. RESULTS Average RNFL thickness was significantly reduced in COPD patients compared to healthy controls (SMD = -0.31, 95% CI = -0.48 to -0.14, P = 0.0004, I2 = 0%). Average RNFL thickness did not differ significantly between patients with mild/moderate COPD and healthy controls (SMD = -0.17, 95% CI = -0.39 to 0.04, P = 0.12, I2 = 2%), while a statistically significant reduction in average RNFL thickness was noticed in patients with severe COPD compared to healthy controls (SMD = -0.72, 95% CI = -1.23 to -0.21, P = 0.006, I2 = 83%). Average RNFL thickness was significantly higher in patients with mild/moderate COPD compared to patients with severe COPD (SMD = 0.69, 95% CI = 0.29 to 1.09, P = 0.0008, I2 = 66%). CONCLUSIONS This meta-analysis showed that RNFL thickness was decreased in patients with COPD compared to healthy controls. Patients diagnosed with severe COPD seem to be more affected and have thinner RNFL. [Ophthalmic Surg Lasers Imaging Retina 2024;55:XX-XX.].

Abstract
PURPOSE To evaluate the efficacy and safety of intravitreal aflibercept injections for diabetic macular edema (DME) treatment in a tertiary referral center in Greece. METHODS ADMIRE was a prospective, observational cohort study of patients with DME. Efficacy was assessed by change in best-corrected visual acuity (BCVA) and central subfield thickness (CST) from baseline to month 36 after treatment with intravitreal aflibercept in treatment-naive patients and previously treated patients. Safety was evaluated by recording any patients-reported events. RESULTS Participants in the study were 94 patients with DME, 70 treatment naive and 24 previously treated with ranibizumab. At month 36 of the follow-up period, the mean change in BCVA was +7.4 letters compared to baseline (p < .001). The mean change in BCVA in treatment-naive patients was +8.9 letters and differed significantly compared to previously treated patients (+5.9 letters, p = .041). In addition, patients who received a loading dose of 5 monthly injections at the initiation of treatment provided better VA outcomes (+11.4 vs. +6.1 letters, p < .001). Accordingly, the mean CST at month 36 (369.6 ± 72.8 μm) was significantly decreased compared to baseline (479.2 ± 68.3 μm, p < .001). Overall, the mean number of injections at month 36 was 13.4. Safety analysis showed that the reported ocular adverse events during the 36-month study period were mild and not sight-threatening. CONCLUSION Intravitreal aflibercept was found to be safe and effective for the treatment of DME in real-life in a Greek population. Treatment-naive patients and those who received a loading dose of five consecutive monthly injections at initiation of treatment exhibited better outcomes, suggesting that early and effective treatment may prevent vision loss.

Abstract
PURPOSE The purpose of this study was to investigate the effect of gas tamponade on microvascular changes in patients with rhegmatogenous retinal detachment (RRD), who underwent pars plana vitrectomy (PPV), using optical coherence tomography angiography (OCTA). METHODS Participants in this study were 48 patients with RRD, who were treated with PPV and gas tamponade without internal limiting membrane peeling. All participants underwent slit-lamp examination, fundoscopy, spectral domain-optical coherence tomography and optical coherence tomography angiography at month 6 postoperatively. The fellow untreated eyes were also examined and served as the control data. RESULTS A statistically significant enlargement in the foveal avascular zone (FAZ) in both the superficial (p = 0.002) and the deep capillary plexus (p = 0.01) was noticed 6 months postoperatively in patients with RRD treated with PPV compared to the fellow eyes. The foveal avascular zone perimeter was increased in the operated eyes in the deep capillary plexus (p = 0.0003) and the foveal avascular zone circularity was decreased in both the superficial (p = 0.045) and the deep capillary plexus (p < 0.001) compared to the fellow eyes. The vessel density was not significantly different between the operated and the fellow eyes in the superficial and the deep capillary plexus. The vessel density and the foveal avascular zone parameters were comparable between the C3F8 and SF6 groups. CONCLUSION Specific microvascular indices as measured by OCTA were statistically different between the operated and the fellow eyes in the superficial and deep capillary plexus. C3F8 and SF6 as gas tamponades did not seem to differ in their impact on the microvascular parameters.

Abstract
PURPOSE Τo evaluate the evolution of macular atrophy (MA) in patients with neovascular AMD (nAMD), compared with their fellow eyes exhibiting dry AMD (dAMD). METHODS This retrospective study included 124 patients from three centers treated with anti-VEGF in their nAMD eye and having dAMD in the fellow eye. Patients without MA at baseline were analyzed to study the time to first MA development. Synchronous and unsynchronous time course of MA was also studied. MA was evaluated using near-infrared images, while all available optical coherence tomography (OCT) images were used to confirm the criteria proposed by the Classification of Atrophy Meetings group for complete MA. RESULTS MA first detection in nAMD eyes increased significantly from year 2 to 6 compared to dAMD eyes. Over the study's follow-up, 45.1% of nAMD-E developed MA, compared to 16.5% of fellow eyes (p < 0.001). When MA in the two eyes was compared in a synchronous paired manner over 4 years, nAMD eyes had an average MA progression rate of 0.275 mm/year versus 0.110 mm/year in their fellow dAMD eyes. Multivariate ANOVA revealed significant time (p < 0.001), eye (p = 0.003), and time-eye interaction (p < 0.001) effects. However, when MA did develop in dAMD eyes and was compared in an asynchronous manner to MA of nAMD eyes, it was found to progress faster in dAMD eyes (dAMD: 0.295 mm/year vs. nAMD: 0.176 mm/year) with a significant time-eye interaction (p = 0.015). CONCLUSIONS In this study, a significant difference in MA incidence and progression was documented in eyes with nAMD under treatment, compared to fellow eye exhibiting dAMD. Eyes with nAMD tended to develop more MA compared to fellow dAMD eyes. However, when atrophy did develop in the fellow dAMD eyes, it progressed faster over time compared to MA in nAMD eyes.

Abstract
BACKGROUND The purpose of this study was to investigate the changes in macular microvasculature using optical coherence tomography angiography (OCTA) in association with functional changes in patients with proliferative diabetic retinopathy (PDR) treated with panretinal photocoagulation (PRP) with a follow up of 12 months. METHODS The participants in this study were 28 patients with PDR and no macular oedema, who were eligible for PRP. All participants underwent best-corrected visual acuity (BCVA) measurement, optical coherence tomography (OCT), and OCT angiography (OCTA) at baseline (before treatment) and at months 1, 6, and 12 after the completion of PRP treatment. The comparison of OCTA parameters and BCVA between baseline and months 1, 6, and 12 after PRP was performed. RESULTS There was a statistically significant decrease in foveal avascular zone (FAZ) area at months 6 and 12 of the follow-up period compared to baseline (p = 0.014 and p = 0.011 for month 6 and 12, respectively). Of note is that FAZ became significantly more circular 6 months after PRP (p = 0.009), and remained so at month 12 (p = 0.015). There was a significant increase in the mean foveal and parafoveal vessel density (VD) at all quadrants at the superficial capillary plexus (SCP) at month 6 and month 12 after PRP compared to baseline. No difference was noticed in VD at the deep capillary plexus (DCP) at any time-point of the follow up. BCVA remained the same throughout the follow-up period. CONCLUSIONS At months 6 and 12 after PRP, foveal and parafoveal VD at SCP significantly increased compared to baseline, while the FAZ area significantly decreased and FAZ became more circular.

Abstract
Cancer-associated retinopathy (CAR) is a rare paraneoplastic disorder mediated by auto-antibodies that cross-react with retinal antigens leading to gradual visual defects. Early diagnosis and initiation of treatment is crucial to avoid permanent visual loss. Although most patients with CAR respond to intravenous steroids and intravenous immunoglobulin (IVIG), there are some cases refractory to the aforementioned treatment strategies. The present study describes a case of CAR in a patient with ovarian cancer that was initially resistant to most treatment regimens (chemotherapy, steroids, IVIG). Treatment with rituximab at 375 mg/m2 and oral cyclophosphamide was administered and the patient showed marked improvement of visual acuity. Electroretinogram showed a 40 and 10% improvement in scotopic and photopic vision, respectively. Notably, at the most recent follow up, the patient was still in remission. In conclusion, treatment with intravenous rituximab and oral cyclophosphamide is a promising treatment option for those cases of CAR that do not respond to steroids, immunomodulatory agents and IVIG.

Abstract
PURPOSE To investigate changes in vision-related quality of life in patients treated with pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD) and compare groups according to the type of gas tamponade used. METHODS Participants in this study were 48 patients with RRD who were treated with PPV and gas tamponade (sulfur hexafluoride (SF6) or perfluoropropane (C3F8)) without internal limiting membrane peeling. All participants underwent slit-lamp examination, fundoscopy, axial-length measurement, and completed the Vision Function Questionnaire-25 (VFQ-25) at month six postoperatively. We compared VFQ-25 composite and subscale scores in the SF6 and C3F8 groups and investigated any correlations between age, best corrected visual acuity (BCVA), axial length, and VFQ-25 scores. RESULTS The demographic and clinical characteristics of the two groups (axial length, macular status, retinal detachment extent, duration of symptoms, and lens status) were comparable between the two groups. We found a statistically significant decrease in general vision (GV), ocular pain (OP), and driving (D) scores in the C3F8 group compared to the SF6 group. The VFQ-25 composite score was comparable in the two groups. Similarly, all other subscales of the VFQ-25 did not differ significantly between the two groups. Age and BCVA did not significantly correlate with VFQ-25 composite and subscale scores. CONCLUSION Specific VFQ-25 subscales were decreased in patients with RRD treated with C3F8 as a gas tamponade compared to SF6. This finding warrants further research in the tamponade agents used in PPV surgeries.

Abstract
PURPOSE To investigate changes in retinal microcirculation in patients recovered from COVID-19 infection compared to healthy controls, using optical coherence tomography-angiography. METHODS Meta-analysis of eligible studies comparing retinal microcirculation between patients recovered from COVID-19 infection and healthy controls up to 7th of September 2022 was performed, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2009 guidelines. The following search algorithm was used: (COVID-19 OR coronavirus) AND (retina OR optical coherence tomography OR optical coherence tomography angiography OR vessel density OR foveal avascular zone). Standardized Mean Difference (SMD) with 95% confidence interval (CI) was calculated to compare continuous variables. Revman 5.3 was used for the analysis. RESULTS 12 studies were included in our analysis. Foveal avascular zone (FAZ) area was larger in patients recovered from COVID-19 infection compared to healthy controls, while there was no statistically significant difference in FAZ perimeter between the two groups. The foveal, parafoveal and whole image vessel density in the superficial capillary plexus showed no significant difference between the two groups. The foveal, parafoveal and whole image vessel density in the deep capillary plexus was statistically lower in patients recovered from COVID-19 compared to healthy controls. CONCLUSION FAZ area was enlarged and foveal, parafoveal and whole image vessel density in deep capillary plexus were reduced in patients recovered from COVID-19 infection compared to healthy controls, suggesting that COVID-19 infection may induce long-term retinal microvascular changes in patients recovered from the virus infection.

Abstract
A 65-year-old male patient presented to the ED complaining of blurred vision in the left eye for the last three days. The patient had just recovered from COVID-19 infection and had a negative polymerase chain reaction (PCR) test two days after the initiation of symptoms. His family and medical history were clear. Ophthalmological examination and imaging revealed branch retinal vein occlusion (BRVO) with macular edema in the left eye, while the right eye was normal. The visual acuity was 6/6 in the right eye and 6/36 in the left eye. Laboratory tests, as well as the full cardiovascular and thrombophilia evaluation, were normal. Since the patient did not have known risk factors for BRVO, we hypothesize that it was related to COVID-19 infection. However, the causality between the two entities remains under investigation.

Abstract
INTRODUCTION The aim of this study was to investigate the possible correlation between peripheral blood biomarkers and morphological characteristics of retinal imaging in patients with retinal vein occlusion (RVO). METHODS Participants in this cross-sectional observational study were 65 consecutive patients (65 eyes) with treatment-naïve RVO, who underwent spectral-domain optical coherence tomography (SD-OCT) and fundus fluorescein angiography (FFA). In addition, peripheral blood samples were taken to evaluate full blood count and biochemical parameters. The association between imaging characteristics and laboratory parameters was examined. RESULTS Eyes with subretinal fluid presented significantly higher neutrophil-to-lymphocyte ratios (p = 0.028). Hyperreflective foci on SD-OCT were found to be associated with higher triglyceride levels (p = 0.024). The presence of cysts on SD-OCT was associated with significantly higher triglycerides (p = 0.010). Central subfield thickness (CST) higher than 464 μm was associated with higher lymphocyte count (p = 0.016) and higher urea (p = 0.015). No significant associations were found between laboratory parameters and intraretinal fluid, ellipsoid zone and external limiting membrane condition, or epiretinal membrane and macular ischemia. CONCLUSIONS Specific imaging morphological characteristics were found to be associated with laboratory parameters in patients with RVO. These findings may help reveal the pathophysiology of RVO and its correlation with the development of specific clinical signs, while they could guide individualized treatment.

Phacoemulsification versus Phacoemulsification/Trabeculectomy for the Treatment of Primary Open-Angle Glaucoma Coexistent with Cataract: A Comparative Study. Medicina (B Aires) 2023; 59:medicina59030470. [PMID: 36984471 PMCID: PMC10057514 DOI: 10.3390/medicina59030470] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2022] [Revised: 02/17/2023] [Accepted: 02/20/2023] [Indexed: 03/02/2023] Open
Abstract
Background: The purpose of this study was to evaluate the clinical outcomes in patients with primary open-angle glaucoma (POAG) and coexistent cataract treated with phacoemulsification cataract surgery, either alone or in combination with trabeculectomy. Methods: Participants in this retrospective study were 52 patients diagnosed with previously controlled POAG and coexistent cataract, who underwent either uneventful phacoemulsification cataract surgery (Group I, n = 27) or combined uneventful phacoemulsification cataract surgery and trabeculectomy (Group II, n = 25), with at least a 24-month postoperative follow-up. We recorded the changes in intraocular pressure (IOP) and in the need of anti-glaucoma medications before and after surgical procedures. Results: There was a statistically significant decrease in IOP at postoperative day 7 in both groups (p < 0.001), which remained until the end of the 24-month follow-up. At month 24, the two groups did not differ significantly in terms of IOP (14.3 ± 1.4 vs. 13.1 ± 1.2 for Group I and Group II, respectively; p = 0.447). In addition, there was a statistically significant decrease in the number of anti-glaucoma medications needed at postoperative day 7 in both groups (p < 0.001 for both groups compared to baseline). At month 24, patients in both groups needed about one additional anti-glaucoma medication to control their IOP. Of note, during the first month after surgery, 20% of patients in Group II needed 0.1 mL 5-FU injections to the bleb, although antimetabolites were not used in the primary surgery. Conclusions: Both surgical interventions, namely phacoemulsification cataract surgery alone and phacoemulsification/trabeculectomy, were found to be effective in the management of POAG with coexistent cataract, presenting a significant decrease in IOP and in the need of anti-glaucoma medications postoperatively at a long-term follow-up period of 24 months.

Alterations in Retinal Vessel Diameters in Patients with Retinal Vein Occlusion before and after Treatment with Intravitreal Ranibizumab. J Pers Med 2023; 13:jpm13020351. [PMID: 36836585 PMCID: PMC9963538 DOI: 10.3390/jpm13020351] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 02/09/2023] [Accepted: 02/16/2023] [Indexed: 02/19/2023] Open
Abstract
Purpose: To investigate the alterations of retinal vessel diameters in patients with macular edema secondary to retinal vein occlusion (RVO), before and after treatment with intravitreal ranibizumab. Methods: Digital retinal images were obtained from 16 patients and retinal vessel diameters were measured before and three months after treatment with intravitreal ranibizumab with validated software to determine central retinal arteriolar and venular equivalents, as well as arteriolar to venular ratio. Results: In 17 eyes of 16 patients with macular edema secondary to RVO (10 with branch RVO and 6 with central RVO) aged 67 ± 10.2 years, we found that diameters of both retinal arterioles and venules were significantly decreased after intravitreal ranibizumab treatment. Specifically, the central retinal arteriolar equivalent was 215.2 ± 11.2 μm at baseline and 201.2 ± 11.1 μm at month 3 after treatment (p < 0.001), while the central retinal venular equivalent was 233.8 ± 29.6 μm before treatment versus 207.6 ± 21.7 μm at month 3 after treatment (p < 0.001). Conclusions: A significant vasoconstriction in both retinal arterioles and venules in patients with RVO was found at month 3 after intravitreal ranibizumab treatment compared to baseline. This could be of clinical importance, since the degree of vasoconstriction might be an early marker of treatment efficacy, compatible with the idea that hypoxia is the major trigger of VEGF in RVO. Further studies should be conducted to confirm our findings.

Abstract
Tertiary outpatient ophthalmology clinics are high-risk environments for COVID-19 transmission, especially retina clinics, where regular follow-up is needed for elderly patients with multiple comorbidities. Intravitreal injection therapy (IVT) for chronic macular diseases, is one of the most common procedures performed, associated with a significant burden of care because of the vigorous treatment regimen associated with multiple investigations. While minimizing the risk of COVID-19 infection transmission is a priority, this must be balanced against the continued provision of sight-saving ophthalmic care to patients at risk of permanent vision loss. This review aims to give evidence-based guidelines on managing IVT during the COVID-19 pandemic in common macular diseases such as age-related macular degeneration, diabetic macula edema and retinal vascular disease and to report on how the COVID-19 pandemic has affected IVT practices worldwide. To illustrate some real-world examples, 18 participants in the International Retina Collaborative, from 15 countries and across four continents, were surveyed regarding pre- and during- COVID-19 pandemic IVT practices in tertiary ophthalmic centers. The majority of centers reported a reduction in the number of appointments to reduce the risk of the spread of COVID-19 with varying changes to their IVT regimen to treat various macula diseases. Due to the constantly evolving nature of the COVID-19 pandemic, and the uncertainty about the normal resumption of health services, we suggest that new solutions for eye healthcare provision, like telemedicine, may be adopted in the future when we consider new long-term adaptations required to cope with the COVID-19 pandemic.

Abstract
PURPOSE To investigate potential laboratory and imaging biomarkers as treatment response predictors to intravitreal anti-vascular endothelial growth factor (anti-VEGF) agents in patients with diabetic macular edema (DME). METHODS The study included 36 treatment naïve patients with DME, treated with intravitreal anti-VEGF agents and followed-up for 12 months. At baseline, all participants underwent best-corrected visual acuity (BCVA) measurement, dilated fundoscopy, optical coherence tomography, color fundus photography and fluorescein angiography, while full blood count and biochemical analysis of various parameters was also performed. At month 12, treatment response was examined and classified as "favorable" or "non-response". Potential associations between laboratory/imaging biomarkers and treatment response were assessed. RESULTS Univariate analysis showed that favorable response at month 12 after initiation of anti-VEGF treatment was correlated with baseline central subfield thickness (CST)≤405 μm (p < .001), absence of subretinal fluid (p = .034), absence of exudates (p = .041), absence of disorganization of the inner retinal layers (p = .037), intact ellipsoid zone (EZ) and external limiting membrane (ELM) (p < .001 and p = .002, respectively), absence of epiretinal membrane (ERM) (p = .040) and absence of macular ischemia (p = .042), while increased lipoprotein(a) was associated with no treatment response (p = .025). At the multivariate analysis, CST was found to be independent predictor of treatment response, while EZ, ELM and ERM were found to predict treatment response perfectly and they could not be entered in the model. CONCLUSION Intact EZ and ELM, absence of ERM and CST≤405 μm at baseline can predict favorable treatment response in patients with treatment naïve DME, while no correlation with baseline laboratory parameters was found.

Disentangling the association between retinal non-perfusion and anti-VEGF agents in diabetic retinopathy. Eye (Lond) 2022; 36:692-703. [PMID: 34408316 PMCID: PMC8956693 DOI: 10.1038/s41433-021-01750-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2021] [Revised: 07/29/2021] [Accepted: 08/06/2021] [Indexed: 02/07/2023] Open
Abstract
Diabetic retinopathy (DR) is the most common microvascular complication of diabetes mellitus (DM) and the leading cause of blindness in patients with DM. In the pathogenesis of DR, chronic hyperglycemia leads to biochemical and structural alterations in retinal blood vessels' wall, resulting in hyperpermeability and non-perfusion. Since vascular endothelial growth factor (VEGF) has been found to play a significant role in the pathogenesis of DR, this review sheds light on the effect of intravitreal anti-VEGF agents on retinal non-perfusion in patients with DR. Based on the existing literature, anti-VEGF agents have been shown to improve DR severity, although they cannot reverse retinal ischemia. The results of the published studies are controversial and differ based on the location of retinal non-perfusion, as well as the imaging modality used to assess retinal non-perfusion. In cases of macular non-perfusion, most of studies showed no change in both fundus fluorescein angiography (FFA) and optical coherence tomography (OCTA) in patients with DR treated with intravitreal anti-VEGF agents, while few studies reported worsening of non-perfusion with enlargement of foveal avascular zone (FAZ). Regarding peripheral ischemia, studies using wide-field-FFA demonstrated an improvement or stability in non-perfusion areas after anti-VEGF treatment. However, the use of wide-field-OCTA revealed no signs of re-perfusion of retinal vessels post anti-VEGF treatment. Further prospective studies with long follow-up and large sample size are still needed to draw solid conclusions.

Abstract
INTRODUCTION To review the existing literature about the optical coherence tomography angiography (OCTA) findings regarding peripapillary and macular vessel density (VD) in patients with pseudoexfoliative glaucoma (PXG). METHODS A comprehensive search of the PubMed database was conducted to include articles up to November 1, 2021, using an appropriate search algorithm. The retrieved articles were assessed for eligibility and filtered manually to exclude duplicates, while articles and book chapters cited in the reference lists of the eligible articles obtained by this method were reviewed so as not to miss any relevant studies. RESULTS There is consistency among the studies published so far that a significant decrease in peripapillary VD exists in eyes with PXG compared to controls, and macular VD has also been reported to be significantly lower in PXG eyes than controls. However, the existing literature remains controversial regarding OCTA findings in eyes with PXG compared to those with primary open-angle glaucoma (POAG). Several studies have found that peripapillary VD and macular VD were significantly lower in PXG than POAG, while other studies reported no significant difference. CONCLUSIONS Eyes with PXG were found to present decreased peripapillary and macular VD compared to control eyes, suggesting that a vascular component, including optic nerve hypoperfusion, may be implicated in the pathogenesis of PXG.

Abstract
Background: The global burden of hypertension is constantly increasing with adverse cardiovascular and ocular sequelae. The association between elevated blood pressure and choroidal thickness (CT), as assessed via optical coherence tomography (OCT), is poorly understood. Objectives and Design: Studies including hypertensive adults and normotensive controls undergoing OCT were evaluated for inclusion in this meta-analysis. The primary endpoint was CT difference between hypertensive and normotensive adults. Data Sources and Methods: We conducted a systematic review and after searching 1011 results from MEDLINE, ClinicalTrials.gov, medRxiv and Cochrane Library, six studies were deemed eligible and were pooled according to a random-effect model. Results: A statistically significant reduction in choroidal thickness was found in hypertensive adults ( n = 454) as compared with normotensive controls ( n = 365) [mean difference: −0.77; 95% confidence intervals: (−1.20, −0.34); p = 0.0004]. The main limitations of this meta-analysis are the relatively small population included and the high statistical heterogeneity ( I2 = 87%) among the various studies. Of note, after excluding one study the heterogeneity was markedly reduced. Conclusion: Choroidal thickness is reduced among hypertensive subjects compared with normotensive controls. This finding mandates further examination in the context of long-term clinical outcomes.

Abstract
PURPOSE To investigate the adjunct efficacy and safety of vitamin supplements, including resveratrol, in patients with diabetic macular edema (DME) treated with intravitreal anti-vascular endothelial factor (anti-VEGF) agents. METHODS Participants in this prospective study were 45 patients with DME, who were treated with either intravitreal anti-VEGF injections (n = 23, Group I) or with combination of intravitreal anti-VEGF injections and vitamin supplements, including resveratrol (n = 22, Group II). All patients underwent visual acuity measurement, slit-lamp examination and spectral domain-optical coherence tomography (SD-OCT) at baseline and monthly after the loading phase of three-monthly anti-VEGF injections, following a PRN protocol. RESULTS There was a statistically significant improvement in visual acuity in both groups at month 12 compared to baseline, although the mean change in visual acuity did not differ between the two groups (p = 0.183). Accordingly, there was a statistically significant decrease in central retinal thickness in both groups at month 12 compared to baseline, while the mean difference in central retinal thickness was significantly greater in the "combination" group. The mean number of intravitreal anti-VEGF injection was less in Group II (6.45 ± 1.12 in Group II vs. 7.39 ± 1.31 in Group I, p = 0.018). CONCLUSIONS Vitamin supplements with resveratrol was found to be an effective adjunct to intravitreal anti-VEGF injections in patients with DME, offering better anatomic restoration with less injections at the 12-month follow-up.

Abstract
Background: Diabetic retinopathy (DR) is the leading cause of blindness in the working-age population. The purpose of this review is to gather the existing literature regarding the use of the approved anti-vascular endothelial growth (anti-VEGF) agents in the treatment of DR. Methods: A comprehensive literature review in PubMed engine search was performed for articles written in English language up to 1 July 2021, using the keywords “diabetic retinopathy”, “ranibizumab”, “aflibercept”, and “anti-VEGF”. Emphasis was given on pivotal trials and recent robust studies. Results: Intravitreal anti-VEGF agents have been found to significantly improve visual acuity and reduce retinal thickness in patients with diabetic macular edema (DME) in a long-term follow-up ranging from 1 to 5 years and are considered the standard-of-care in such patients. Regarding DR, intravitreal anti-VEGF agents provided ≥2-step improvement in DR severity on color fundus photography in about 30–35% of patients with NPDR at baseline, in the majority of clinical trials originally designed to evaluate the efficacy of intravitreal anti-VEGF agents in patients with DME. Protocol S and CLARITY study have firstly reported that intravitreal anti-VEGF agents are non-inferior to panretinal photocoagulation (PRP) in patients with proliferative DR (PDR). However, the use of new imaging modalities, such as optical coherence tomography-angiography and wide-field fluorescein angiography, reveals conflicting results about the impact of anti-VEGF agents on the regression of retinal non-perfusion in patients with DR. Furthermore, one should consider the high “loss to follow-up” rate and its devastating consequences especially in patients with PDR, when deciding to treat the latter with intravitreal anti-VEGF agents alone compared to PRP. In patients with PDR, combination of treatment of intravitreal anti-VEGF agents and PRP has been also supported. Moreover, in the specific case of vitreous hemorrhage or tractional retinal detachment as complications of PDR, intravitreal anti-VEGF agents have been found to be beneficial as an adjunct to pars plana vitrectomy (PPV), most commonly given 3–7 days before PPV, offering reduction in the recurrence of vitreous hemorrhage. Conclusions: There is no general consensus regarding the use of intravitreal anti-VEGF agents in patients with DR. Although anti-VEGF agents are the gold standard in the treatment of DME and seem to improve DR severity, challenges in their use exist and should be taken into account in the decision of treatment, based on an individualized approach.

Abstract
The role of topical non-steroidal anti-inflammatory drugs (NSAIDs) in routine cataract surgery has been established since decades. Topical NSAIDs have been shown to reduce postoperative ocular inflammation and pain, preserve intraoperative mydriasis, and reduce the risk of postoperative cystoid macular oedema, whilst carrying a very low side-effect profile. Nepafenac is one of the currently available topical NSAIDs. The studies have shown that is has a high ocular penetration, allowing for potentially better results than other NSAIDs. This review gathers the current literature on the role of nepafenac in cataract surgery aiming to help surgeons maximise the benefits of its use to achieve improved surgical outcomes.

Abstract
A 71-year-old woman presented with progressive, bilateral, blurred vision and nyctalopia for the last 6 months. Her past medical history included total hysterectomy and chemotherapy for ovarian cancer 4 years ago, without metastases. Optical coherence tomography revealed outer retinal layers' thinning bilaterally, while diffuse retinal pigment epithelium abnormalities were found in fundus autofluorescence. Full-field electroretinogram showed abnormalities in both a- and b-waves with significant reduction of retinal sensitivity, affecting however more the rod system. The patient was positive for alpha-enolase and was diagnosed with cancer-associated retinopathy (CAR), which developed 4-year primary cancer. Computerized tomography scan revealed an enlarged para-aortic lymph node at the left kidney, and the patient was started on chemotherapy, combined with immunosuppressive treatment. In conclusion, CAR should be suspected in patients experiencing unexplained visual disturbances, especially in the context of previous cancer.

Abstract
PURPOSE To evaluate the sensitivity of Spectral Domain Optical Coherence Tomography (SD-OCT) regarding the diagnosis of posterior vitreous detachment (PVD) in vitreomacular interface disorders (VID). METHODS A total of 48 eyes of 48 patients were included in this prospective cohort study. PVD in eyes with VID was investigated. We determined the status of posterior vitreous cortex using slit lamp (SL) biomicroscopy and SD-OCT preoperatively, during vitrectomy and on the intraoperative video recording. Sensitivity and specificity of the examining methods were analysed. Four masked independent examiners participated in this study. RESULTS PVD was diagnosed in 16 eyes (33.3%) on SD-OCT, 20 eyes (41.7%) on SL examination and 28 eyes (58.3%) during vitrectomy. Sensitivity and specificity for diagnosis of PVD was 37.5% and 31.3% using SD-OCT, 90% and 64.3% on the SL examination, 92.9% and 90% on the video recording respectively, compared to the intraoperative PVD diagnosis. CONCLUSION SD-OCT shows a relatively low detection sensitivity of PVD in VID. Thorough OCT investigation is necessary to establish an appropriate diagnosis of PVD and treatment in VID.

Abstract
Introduction: Diabetic retinopathy (DR) is the most common microvascular complication of diabetes mellitus and the leading cause of blindness in young adults. Prior to anti-vascular endothelial growth factor (anti-VEGF) agents, the treatment of DR was based on control of systemic factors and laser photocoagulation. Over the past decade, the use of anti-VEGF agents has revolutionized the treatment of DR, including diabetic macular edema (DME).Areas covered: Ranibizumab has been proven to be effective for the treatment of DME in large clinical trials, while patients in these studies have been assessed in terms of DR severity change. In this review, evidence from randomized trials regarding the use of ranibizumab for DR treatment is presented.Expert opinion: A comprehensive presentation of randomized clinical trials evaluating ranibizumab for DR indicates that it is effective and safe, offering improvement of DR severity in both non-proliferative and proliferative forms. However, there is no general consensus regarding the exact treatment regimen in patients with DR, while the effect of ranibizumab on the progression of retinal ischemia remains unclear.

Abstract
PURPOSE To evaluate the association between serum vitamin B12/folate and retinal vein occlusion (RVO). METHODS A comprehensive search of the PubMed database was performed, which identified 271 abstracts to be screened. Ten studies met our inclusion criteria and a meta-analysis of these comparative case-control studies was performed on the mean ± standard deviation serum vitamin B12 and folate levels, without language restrictions. Nine studies with 720 patients with RVO and 613 controls were included in the meta-analysis for vitamin B12, and 10 studies with 784 patients with RVO and 677 controls in the meta-analysis for folate. RESULTS There was no statistically significant difference between patients with RVO and controls in serum vitamin B12 levels (mean difference: - 40.25 pg/mL, p = 0.28), either central RVO (mean difference: - 18.24 pg/mL, p = 0.71) or branch RVO (mean difference: - 23.56 pg/mL, p = 0.48). On the contrary, the plasma folate level was significantly lower in RVO patients than in controls (mean difference: - 1.34 ng/mL, p = 0.001), as well as in patients with CRVO compared to controls (mean difference: - 1.48 ng/mL, p = 0.006), but not in BRVO patients (mean difference: - 0.72 ng/mL, p = 0.11). CONCLUSIONS RVO is associated with low serum folate levels, but not with serum vitamin B12 levels.

Purpose To evaluate the effect of the coronavirus disease 2019 (COVID-19)-related lockdown in the management of patients with diabetic retinopathy (DR), including diabetic macular edema (DME), in a tertiary reference center in Greece. Methods In this retrospective study, we first compared the number of patients who were diagnosed with DR or DME in our clinic during the period of the lockdown and during the same period of the previous year. In addition, we included consecutive patients with DR or DME, who were followed up and treated regularly in our clinic and their appointments deferred due to lockdown, so as to compare the visual acuity, fundoscopy, and optical coherence tomography (OCT) findings prior to and post lockdown. Results During the lockdown period, there was a statistically significant decrease in patients with DR and DME as compared to the same period in the previous year. Regarding patients with previously diagnosed DME, there was a statistically significant worsening in their visual acuity and central retinal thickness after lockdown as compared to the last visit before lockdown (p<0.001 for both comparisons). Concerning patients diagnosed with DR and without DME before lockdown, 30% of patients with severe non-proliferative diabetic retinopathy (NDPR) and 8.3% of patients with quiescent proliferative DR (PDR) progressed to active PDR while four out of 107 patients (3.7%) developed DME during the lockdown. Multivariate regression analysis revealed that only the time interval between the last visit before lockdown and the first visit after the lockdown was associated with the best-corrected visual acuity (BCVA) change (p=0.017). Conclusions The COVID-19-related lockdown was related to the postponement in patient care, which resulted in significantly worse visual acuity outcomes in patients with DR.

Abstract
OBJECTIVE The coronavirus disease 2019 (COVID-19) pandemic has imposed measures of social distancing and barriers in delivery of "in person" education. Institutions, involved in training the next generation of ophthalmologists, are using alternative teaching methods to maintain the standard of education. METHODS We conducted a worldwide survey among physicians, who are actively involved in Ophthalmology-related education, between 3 and 14 April 2020. The expert survey, developed on the basis of literature search and focus group discussions, comprised 23 questions addressing the use of e-learning in Ophthalmology during the COVID-19 pandemic. RESULTS A total of 321 participants from both academic and non-academic institutions worldwide, with variable practice experience and expertise, completed the survey. Before the pandemic, the majority of participants used traditional training modalities, including lectures, grand rounds and journal clubs, and 48% did not use any e-learning. There was a statistically significant increase in the use of all e-learning alternatives during the pandemic (p < 0.001), associated mainly with the availability of e-learning facilities (p < 0.001) and the academic character of institutions (p < 0.001). Zoom® was recognized as the mostly used platform for virtual teaching. Although theoretical teaching may take place, the surgical training of residents/fellows was dramatically reduced. The latter was significantly associated with participants' perspectives about teaching practices (p < 0.001). CONCLUSION COVID-19 pandemic imposed great challenges in the educational field of Ophthalmology. The experience related to virtual training in Ophthalmology, gained during the pandemic, may change the traditional teaching practices in the world and provide new educational opportunities.

Abstract
BACKGROUND The purpose of this study is the development and validation of a novel and robust genotyping method for a new lysyl oxidase-like 1 (LOXL1) intronic polymorphism (rs11638944, C > G) and the investigation of its potential association with pseudoexfoliation syndrome (PXS) and pseudoexfoliation glaucoma (PXG) in a Greek population. MATERIAL AND METHODS 242 DNA samples from 49 PXS, 64 PXG, 50 primary open-angle glaucoma (POAG) patients and 79 healthy age-matched controls were analyzed. Novel methodologies were developed and optimized, in order to genotype the intronic LOXL1 polymorphism: a) a real-time qPCR and melting curve analysis in the Light Cycler platform for rapid and cost-effective analysis and, b) a conventional PCR-RFLP method for analysis of a small number of samples. In selected samples, validity was checked with the reference DNA Sequencing method. RESULTS The real-time qPCR methodology was reliable, demonstrating good efficiency, reproducibility, accuracy in genotyping (100% concordance with the PCR-RFLP method and DNA Sequencing), with good allele discrimination (Tm = 53.26°C for C allele, Tm = 61.83°C for G allele, ΔTm = 8.57°C). The results were characterized by Hardy-Weinberg equilibrium in all groups. An increase from 18% in healthy controls to 61% in PXS patients was detected for the G/G homozygote thus, the C allele is protective for PXS with OR = 0.22 (95%CI: 0.11-0.42, p < .0001). Moreover, an increase from 18% in healthy controls to 70% in PXG patients was detected for the G/G homozygote thus, the C allele is protective for PXG with OR = 0.13 (95%CI: 0.06-0.25, p < .0001). CONCLUSIONS A statistically significant association was verified for the intronic LOXL1 polymorphism rs11638944 and PXS/PXG in a Greek population.

Abstract
Purpose: The purpose of this study was to evaluate health-related quality of life in patients with retinal vein occlusion (RVO) and investigate the possible risk factors for poor quality of life in patients with RVO.Methods: Participants in the study were 67 patients with RVO, 42 male and 25 female, mean-aged 73.1 ± 10.9 years, and 70 sex- and age-matched controls. Demographic data, lifestyle factors and medical history were recorded. All patients underwent best-corrected visual acuity measurement, dilated fundoscopy and optical coherence tomography. All participants completed two questionnaires assessing quality of life (EQ-5D, NEI VFQ-25). Risk factors for health-related quality of life in RVO patients were investigated.Results: Patients with RVO exhibited significantly lower composite score for VFQ-25 compared to controls (74.1 ± 3.8 vs. 91.7 ± 3.9 for patients and controls, respectively, p < .001). In addition, RVO patients had significantly lower EQ-5D Index score compared to controls (0.88 ± 0.15 vs. 0.92 ± 0.12 for patients and controls, respectively, p = .043). Risk factors associated with quality of life in patients with RVO were found the alcohol consumption, the presence of thyroidopathy, coagulation disorders, visual acuity in the eye with RVO, central retinal thickness, the type of edema, the presence of ischemia and the condition of external limiting membrane. In multivariate analysis, only alcohol consumption and visual acuity in the eye with RVO were found to be independent risk factors, affecting quality of life in RVO patients.Conclusions: Patients with RVO presented lower quality of life in comparison with controls. Potential risk factors should be taken into account and their early detection may improve quality of life in such patients and lead to targeted health policies.

Abstract
A macular hole (MH) may be a significant complication in patients with high myopia. The recently reported inverted internal limiting membrane (ILM) flap technique is a promising alternative to treat myopic MHs. We performed a meta-analysis of the published anatomical and functional results of the "inverted ILM flap" technique for the treatment of myopic MH with or without retinal detachment (RD). Our results showed that the inverted ILM flap technique, either covering or insertion, is an effective method for treating myopic MH with or without RD and provides high MH closure, ranging from 91.8% to 97.1%. Despite the high MH closure rate, the pooled visual acuity improvement rate was 77.3% and 66.2% in patients with myopic MH without RD, while it was 95% and 80.3% in patients with myopic MHRD, using "covering" and "insertion" ILM flap technique, respectively. Potential complications included reopening or persistence of MH, development of RD, choroidal detachment, ocular hypertension, and chorioretinal atrophy.

Abstract
PURPOSE To evaluate the characteristics of corneal parameters in patients with diabetic macular oedema (DME) treated with intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections. METHODS Participants in this study were 36 patients with DME, treated with either intravitreal ranibizumab (n = 16) or aflibercept (n = 20). All participants underwent best-corrected visual acuity (BCVA) measurement, optical coherence tomography and non-contact specular microscopy to evaluate corneal endothelium parameters (endothelial cell density-ECD, hexagonality, coefficient of variation of the cell size and central corneal thickness-CCT), at baseline and at months 6 and 12 after the first intravitreal injection. Comparisons between baseline and months 6 and 12 were performed. RESULTS There was no statistically significant difference regarding ECD, hexagonality, coefficient of variation of the cell size and CCT at month 6 and 12 post initial injection compared to baseline in patients with DME. BCVA improved significantly at month 6 and 12 compared to baseline (p < 0.001 for both comparisons). Central retinal thickness was significantly reduced at month 6 and 12 compared to baseline (p < 0.001 for both comparisons). CONCLUSION Intravitreal anti-VEGF injections in patients with DME were found not to affect corneal parameters, namely ECD, hexagonality, coefficient of variation of the cell size and CCT at the long-term follow-up of 12 months.

Abstract
PURPOSE To examine the changes in retinal microvasculature in association with retinal layers' condition in patients with rhegmatogenous retinal detachment (RRD) treated with pars plana vitrectomy (PPV). METHODS Participants in this study were 89 patients with macula off RRD, who were successfully treated with PPV and gas tamponade without internal limiting membrane peeling, in two centers. All participants underwent best corrected visual acuity (BCVA) measurement, slit-lamp examination, fundoscopy, spectral domain-optical coherence tomography (SD-OCT) and optical coherence tomography angiography (OCTA) at week 5, month 3 and month 6 postoperatively. The fellow untreated eyes were also examined and served as control data. RESULTS A statistically significant enlargement in foveal avascular zone (FAZ) in both superficial capillary plexus (SCP) and deep capillary plexus (DCP), accompanied with a statistically significant thinning of inner retinal layers, was noticed 5 weeks postoperatively. These changes, namely FAZ enlargement and thinning of inner retinal layers, in the operated eyes compared to the fellow eyes, remained unchanged till month 6 postoperatively. BCVA improved significantly from week 5 to months 3 and 6 postoperatively. The improvement in BCVA was associated with the gradual ellipsoid zone (EZ) recovery from the first (week 5) till the last examination (month 6). CONCLUSIONS The FAZ enlargement in the operated eyes was accompanied with a statistically significant thinning in the inner retinal layers. Inter-correlation of BCVA and EZ integrity was noticed.

Abstract
BACKGROUND Age-related macular degeneration (AMD) is a progressive, multifactorial, degenerative disease and the leading cause of severe visual loss in the elderly population. The exact pathogenesis of AMD remains elusive, being the combination of genetic, environmental, metabolic, and functional processes. A better understanding of the disease's pathophysiology can lead to new treatment targets. The human microbiome seems to be a potential therapeutic pathway for AMD, as it has been recently proven to play a role in its pathogenesis. SUMMARY This review sheds light on the association between the microbiome and AMD. Key Messages: The current evidence based on the existing literature shows that there are differences in taxonomical and functional profiles in the human microbiome between patients with AMD and controls, suggesting that the microbiome is implicated in AMD onset and progression, being a link between AMD and nutrition/diet. Additionally, specific bacterial classes have been proposed as potential biomarkers for AMD diagnosis. Further randomized clinical studies with a large sample are needed to elucidate the role of the microbiome in AMD and to draw more solid conclusions.

Abstract
PURPOSE The purpose of this prospective study was to evaluate potential predictive factors of long-term postoperative outcomes in patients with macula-off rhegmatogenous retinal detachment (RRD) treated with pars plana vitrectomy (PPV). METHODS Participants in this study were 86 patients diagnosed with macula-off RRD, who underwent PPV. Demographic characteristics and preoperative characteristics of RRD were recorded, while best corrected visual acuity (BCVA) was measured preoperatively and at specific postoperative time points (6 weeks and 6, 12, and 24 months). In addition, spectral domain-optical coherence tomography (SD-OCT) characteristics at postoperative week 6 were assessed as potential factors affecting the long-term postoperative visual outcome 24 months after PPV for RRD. RESULTS Increasing age, duration of RD of more than 1 week, presence of proliferative vitreoretinopathy, increasing central retinal thickness, ellipsoid zone disruption, and external limiting membrane disruption were significantly associated with a worse BVCA. BCVA was not associated with gender, lens status, the location of breaks, the gas tamponade agent used in PPV, the presence of subretinal fluid, and intraretinal fluid. CONCLUSIONS It is important to determine predictive factors for visual outcomes in order to inform patients about their prognosis and help in the decision-making process for patient management.

Abstract
PURPOSE To investigate the potential association between peripheral blood biomarkers and morphological characteristics of retinal imaging in patients with diabetic macular edema (DME). METHODS Participants in this cross-sectional study were 36 consecutive patients (36 eyes) with treatment-naïve DME, who underwent spectral domain-optical coherence tomography (SD-OCT), fundus photography, and fundus fluorescein angiography (FFA). In addition, peripheral blood samples were taken to evaluate full blood count and biochemical parameters. Correlation between imaging characteristics and laboratory parameters was examined. RESULTS Eyes with central subfield thickness greater than 405 μm presented significantly higher neutrophils/lymphocytes (p = 0.043) and higher lipoprotein (a) compared to eyes with CST < 405 μm (p = 0.003). Presence of hyperreflective foci on SD-OCT was associated with significantly higher white blood cell count (p = 0.028). Ellipsoid zone disruption was associated with significantly lower hematocrit (p = 0.012), hemoglobin (p = 0.009), and red blood cell count (p = 0.026), as well as with higher lipoprotein (a) (p = 0.015). Macular ischemia on FFA was associated with significantly higher monocytes (p = 0.027) and monocytes/HDL (p = 0.019). No significant associations were found between laboratory parameters and subretinal fluid, intraretinal fluid, exudates, cysts, disorganization of inner retinal layers, epiretinal membrane, and external limiting membrane condition. CONCLUSION Specific imaging morphological characteristics were found to be associated with laboratory parameters in patients with DME. These findings may shed light on the pathophysiology of DME and its correlation with the development of specific clinical signs.

Abstract
Purpose: The purpose of this study was to investigate the changes of optical coherence tomography angiography (OCTA) parameters in diabetic retinopathy (DR) using an updated software with 3D projection artifact removal. Methods: In this cross-sectional observational study, 192 eyes of 111 patients with diabetes mellitus (DM) and 55 eyes of 34 age-matched healthy subjects were included. Diabetic patients were divided into three subgroups: without DR, with mild non-proliferative DR, and with moderate-to-severe non-proliferative DR. All eyes underwent dilated fundoscopy along with 3x3mm and 6x6mm OCTA image acquisition. Vessel density (VD), retinal thickness and foveal avascular zone (FAZ) parameters were analyzed. Correlation analyses between OCTA parameters and DR severity were also performed. Results: There was a statistically significant difference in all OCTA parameters among groups, except for superficial foveal VD in 6x6mm scan and whole image retinal thickness in both 3x3mm and 6x6mm scans, while 3x3mm scan parameters were found to be diagnostically superior to the corresponding ones of 6x6mm scan. As the DR stage progressed, the mean VD values decreased. FD-300, which is the VD of a 300-μm width annulus surrounding FAZ, demonstrated the strongest inverse correlation with DR severity (r = -0.590/rs = -0.562, p < .001) and showed the highest area under the ROC curve (AUROC = 0.833 ± 0.030, p < .001) in scan 3 × 3. Conclusion: OCTA shows progressive decrease of VD parameters with increasing DR severity. Foveal VD, FAZ area, and perimeter are not very useful indexes due to the high interindividual variability of FAZ size. OCTA and specifically FD-300 may serve as a promising DR screening tool for detecting preclinical microvascular alterations.

Abstract
INTRODUCTION The aim of the study was to evaluate the applicability of optical coherence tomography (OCT) angiography (OCTA) for measuring geographic atrophy (GA) areas in age-related macular degeneration (AMD) patients with "foveal" and "no-foveal" sparing disease and compare it to other imaging modalities. METHODS A multimodal imaging protocol was applied, using infrared (IR) imaging, fundus autofluorescence (FAF), OCTA, and en-face OCT in 35 eyes of 23 AMD patients with GA. Patients were classified into 2 groups, with and without foveal sparing disease. GA area measurements for all imaging modalities were compared for each group separately. RESULTS The measured GA area was estimated to be 6.68 ± 3.18 mm2 using IR; 6.99 ± 3.09 mm2 using FAF; 6.56 ± 3.11 mm2 using OCTA, and 6.65 ± 3.14 mm2 using en-face OCT. There was no statistically significant difference in the GA area between different modalities (p = 0.977). When separate analysis was conducted for patients with "foveal" and "no-foveal" sparing disease, although GA measurements in FAF imaging displayed higher numerical values than the other modalities, especially in patients with foveal sparing, no statistically significant difference in the GA area was found between the different imaging modalities in either group (p = 0.816 for foveal sparing; p = 0.992 for no-foveal sparing group). CONCLUSIONS OCTA can be reliably used in the assessment of GA in AMD patients with and without foveal sparing disease. For both groups, measurements are comparable to IR, en-face OCT, and FAF, despite the fact that the latter recorded larger area of GA, mainly in the foveal sparing cases.

Abstract
BACKGROUND While there is a long history of measuring death and disability from injuries, modern research methods must account for the wide spectrum of disability that can occur in an injury, and must provide estimates with sufficient demographic, geographical and temporal detail to be useful for policy makers. The Global Burden of Disease (GBD) 2017 study used methods to provide highly detailed estimates of global injury burden that meet these criteria. METHODS In this study, we report and discuss the methods used in GBD 2017 for injury morbidity and mortality burden estimation. In summary, these methods included estimating cause-specific mortality for every cause of injury, and then estimating incidence for every cause of injury. Non-fatal disability for each cause is then calculated based on the probabilities of suffering from different types of bodily injury experienced. RESULTS GBD 2017 produced morbidity and mortality estimates for 38 causes of injury. Estimates were produced in terms of incidence, prevalence, years lived with disability, cause-specific mortality, years of life lost and disability-adjusted life-years for a 28-year period for 22 age groups, 195 countries and both sexes. CONCLUSIONS GBD 2017 demonstrated a complex and sophisticated series of analytical steps using the largest known database of morbidity and mortality data on injuries. GBD 2017 results should be used to help inform injury prevention policy making and resource allocation. We also identify important avenues for improving injury burden estimation in the future.

Abstract
BACKGROUND Past research in population health trends has shown that injuries form a substantial burden of population health loss. Regular updates to injury burden assessments are critical. We report Global Burden of Disease (GBD) 2017 Study estimates on morbidity and mortality for all injuries. METHODS We reviewed results for injuries from the GBD 2017 study. GBD 2017 measured injury-specific mortality and years of life lost (YLLs) using the Cause of Death Ensemble model. To measure non-fatal injuries, GBD 2017 modelled injury-specific incidence and converted this to prevalence and years lived with disability (YLDs). YLLs and YLDs were summed to calculate disability-adjusted life years (DALYs). FINDINGS In 1990, there were 4 260 493 (4 085 700 to 4 396 138) injury deaths, which increased to 4 484 722 (4 332 010 to 4 585 554) deaths in 2017, while age-standardised mortality decreased from 1079 (1073 to 1086) to 738 (730 to 745) per 100 000. In 1990, there were 354 064 302 (95% uncertainty interval: 338 174 876 to 371 610 802) new cases of injury globally, which increased to 520 710 288 (493 430 247 to 547 988 635) new cases in 2017. During this time, age-standardised incidence decreased non-significantly from 6824 (6534 to 7147) to 6763 (6412 to 7118) per 100 000. Between 1990 and 2017, age-standardised DALYs decreased from 4947 (4655 to 5233) per 100 000 to 3267 (3058 to 3505). INTERPRETATION Injuries are an important cause of health loss globally, though mortality has declined between 1990 and 2017. Future research in injury burden should focus on prevention in high-burden populations, improving data collection and ensuring access to medical care.

Intravitreal ranibizumab alone or in combination with panretinal photocoagulation for the treatment of proliferative diabetic retinopathy with coexistent macular edema: long-term outcomes of a prospective study. Acta Diabetol 2020; 57:1219-1225. [PMID: 32472172 DOI: 10.1007/s00592-020-01548-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/21/2020] [Accepted: 05/12/2020] [Indexed: 12/27/2022]
Abstract
AIMS To compare intravitreal ranibizumab as monotherapy or in combination with panretinal photocoagulation (PRP) in patients with proliferative diabetic retinopathy (PDR) and coexistent diabetic macular edema (DME) in a long-term follow-up of 24 months. METHODS Participants in this prospective study were 47 patients with PDR and concurrent DME, who were randomized at baseline into two groups: (i) the "ranibizumab alone" group (n = 23), which was treated with at least 3 intravitreal ranibizumab injections as a loading phase, and (ii) the "combination" group (n = 24), which was treated with PRP and at least 3 intravitreal ranibizumab injections. Thereafter, all patients were followed up at a pro re nata (PRN) basis, with regular monthly monitoring for 24 months. At each visit, best corrected visual acuity (BCVA) and spectral domain-optical coherence tomography were performed, while regression of neovascularization was also recorded. RESULTS The "combination" group had better control of neovascularization and less events of vitreous hemorrhage than ranibizumab alone through the 2 years. BCVA did not differ significantly between the two groups at months 12 and 24 of the follow-up. The "ranibizumab" alone group presented greater reduction in central retinal thickness at month 12, which did not reach significance at month 24 compared to "combination" group. Greater number of injections was needed in the monotherapy group (mean 14 injections) compared to "combination" group (mean 11 injections) through month 24. CONCLUSIONS Both intravitreal ranibizumab alone or in combination with PRP could be used effectively for the treatment of PDR and coexistent DME. Even though there was no difference in BCVA and CRT at the 24-month follow-up between the two groups, the combination group presented greater regression of neovascularization with less injections.

Abstract
BACKGROUND: The purpose of this retrospective study was to evaluate potential predictive factors of postoperative visual outcome in patients with idiopathic epiretinal membrane (iERM), treated with pars plana vitrectomy (PPV). METHODS: Participants in the study were 46 patients diagnosed with iERM, who underwent PPV. Best-corrected visual acuity measurement and spectral domain-optical coherence tomography (OCT) were performed at baseline (preoperatively), and at months 6 and 12 postoperatively. Demographic characteristics and OCT parameters were assessed as potential predictive factors for postoperative visual outcome. RESULTS: Increasing age, retinal thickness, presence of disorganization of inner retinal layers, ellipsoid zone disruption, and presence of vitreomacular traction were found to be negatively associated with postoperative visual acuity. Gender, presence of subretinal fluid, cysts in the inner or outer nuclear layer, and hyperreflective foci were not found to affect visual acuity. There was statistically significant improvement in visual acuity and central retinal thickness between baseline and months 6 and 12 in the study sample. CONCLUSIONS: It is important to determine predictive factors for visual outcome, so as to inform patients about prognosis and help in the decision-making of patients' management.

Abstract
PURPOSE To evaluate peripapillary retinal nerve fiber layer (RNFL) changes in patients with diabetes mellitus (DM) and compare them with those of normal population. In addition, this study aims to determine potential factors, affecting RNFL changes in patients with DM. METHODS Participants in this study were 107 patients (211 eyes) with DM and 100 healthy controls (200 eyes). Diabetic patients were further classified into four groups depending on severity of diabetic retinopathy (no retinopathy, mild, moderate, severe nonproliferative diabetic retinopathy, and proliferative diabetic retinopathy, while presence of macular edema was also assessed. All participants underwent spectral-domain optical coherence tomography (SD-OCT) to measure RNFL thickness, while demographic and clinical characteristics of the participants were also recorded. RESULTS Patients with DM with or without DR presented significantly decreased peripapillary RNFL thickness in all quadrants. In the diabetic group, the multivariate analysis showed a significant association between decreased average RNFL thickness and increased HbA1c (p < 0.001), longer DM duration (p = 0.007), and more severe diabetic retinopathy status (p = 0.016), while presence of DME, age, gender, hypertension, and hyperlipidemia were not found to be associated with RNFL thickness decrease. CONCLUSION Diabetes mellitus seems to affect RNFL thickness, suggesting that early neurodegenerative changes may occur, potentially before microvascular alterations. Since duration of disease, DR severity, and HbA1c levels were associated with RNFL thinning, modifying glycemic control seems to be important to potentially prevent the development of DM complications.

Abstract
PURPOSE To examine the retinal layers' changes and alterations in retinal microvasculature in patients with rhegmatogenous retinal detachment (RRD) treated with pars plana vitrectomy (PPV). METHODS Participants in this study were 103 patients with RRD, 85 macula off and 18 macula on, who were treated with PPV and gas tamponade without internal limiting membrane peeling, in two centers. All participants underwent best corrected visual acuity measurement, slit-lamp examination, fundoscopy, spectral domain-optical coherence tomography and optical coherence tomography angiography at week 5 and at month 6 postoperatively. The fellow untreated eyes were also examined and served as control data. RESULTS A statistically significant enlargement in foveal avascular zone (FAZ) in both superficial capillary plexus (SCP) and deep capillary plexus (DCP) was noticed 5 weeks postoperatively in patients with RRD treated with PPV compared to the fellow eyes and remained 6 months after surgery. The FAZ enlargement in the operated eyes was accompanied with a statistically significant thinning of the inner retinal layer. In addition, there was a significant decrease in foveal and parafoveal vessel density (VD) in both SCP and DCP in the operated eyes compared to control eyes at week 5 postoperatively, which also remained at postoperative month 6. CONCLUSIONS The study demonstrated that patients with RRD treated with PPV presented changes in the retinal microvasculature in both SCP and DCP, including enlargement of FAZ and decrease in VD. These changes seemed to be associated with inner retinal layer thinning.

Abstract
PURPOSE The purpose of this study was to investigate retinal layers' changes in patients with diabetic macular edema (DME) treated with anti-vascular endothelial growth factor (anti-VEGF) agents and to evaluate if these changes may affect treatment response. METHODS Participants in this prospective study were 110 treatment-naïve patients with center involved DME, who were treated with anti-VEGF agents and followed up for at least 12 months. A qualitative and quantitative analysis of retinal layers that can affect visual acuity was performed. Patients with persistent DME were defined, and factors which could affect this outcome were determined. RESULTS Visual acuity was significantly improved, while there was also a statistically significant reduction in central retinal thickness and in all separate retinal layers' thickness at month 12 compared to baseline (p < 0.001). Visual acuity was associated with central retinal thickness and outer retinal layers' thickness;51.8% of the patients presented with persistent DME at month 12, which was found to be significantly associated with baseline visual acuity and HbA1C levels. CONCLUSIONS Anti-VEGF treatment is effective in reducing retinal thickness as a whole and in all separate retinal layers at 12-month follow-up in patients with DME. Changes in central retinal thickness and in outer retinal layers were found to affect visual acuity. HbA1c was the most significant factor to determine persistence of DME at month 12.
