RESUMEN

In this retrospective case series on neovascular age-related macular degeneration (nAMD), we aimed to improve Choroidal Neovascularization (CNV) visualization in Optical Coherence Tomography Angiography (OCTA) scans by addressing segmentation errors. Out of 198 eyes, 73 OCTA scans required manual segmentation correction. We compared uncorrected scans to those with minimal (2 corrections), moderate (10 corrections), and detailed (50 corrections) efforts targeting falsely segmented Bruch's Membrane (BM). Results showed that 55% of corrected OCTAs exhibited improved quality after manual correction. Notably, minimal correction (2 scans) already led to significant improvements, with additional corrections (10 or 50) not further enhancing expert grading. Reduced background noise and improved CNV identification were observed, with the most substantial improvement after two corrections compared to baseline uncorrected images. In conclusion, our approach of correcting segmentation errors effectively enhances image quality in OCTA scans of nAMD. This study demonstrates the efficacy of the method, with 55% of resegmented OCTA images exhibiting enhanced quality, leading to a notable increase in the proportion of high-quality images from 63 to 83%.

RESUMEN

Background and Objectives: Age-related macular degeneration (AMD) is one of the leading causes of central vision loss among elderly patients, and its dry form accounts for the majority of cases. Although several causes and mechanisms for the development and progression of AMD have previously been identified, the pathogenesis of this complex disease is still not entirely understood. As inflammation and immune system involvement are strongly suggested to play a central role in promoting the degenerative process and stimulating the onset of complications, we aimed to analyze the frequency of serum anti-retinal (ARAs) and anti-endothelial cell antibodies (AECAs) in patients with dry AMD and to determine their relationship with the clinical features of the disease, notably the area of geographic atrophy (GA). Materials and Methods: This study included 41 patients with advanced-stage dry AMD and 50 healthy controls without AMD, matched for gender and age. ARAs were detected by indirect immunofluorescence using monkey retina as an antigen substrate, and the presence of AECAs was determined using cultivated human umbilical vein endothelial cells and primate skeletal muscle. Results: ARAs were detected in 36 (87.8%) AMD patients (titers ranged from 1:20 to 1:320) and in 16 (39.0%) (titers ranged from 1:10 to 1:40) controls (p = 0.0000). Twenty of the forty-one patients (48.8%) were positive for AECAs, while in the control group, AECAs were present only in five sera (10.0%). The titers of AECAs in AMD patients ranged from 1:100 to 1:1000, and in the control group, the AECA titers were 1:100 (p = 0.0001). There were no significant correlations between the presence of AECAs and disease activity. Conclusions: This study demonstrates a higher prevalence of circulating AECAs in patients with dry AMD; however, no correlation was found between the serum levels of these autoantibodies and the area of GA.

RESUMEN

This retrospective study aimed to determine the short-term efficacy and safety of brolucizumab treatment for recalcitrant neovascular age-related macular degeneration (nAMD) in a real-world setting in Taiwan. Recalcitrant nAMD patients who were treated with brolucizumab from November 2021 to August 2022 at Taipei Veterans General Hospital were included. Patients were followed for 3 months after switching to brolucizumab. The primary outcomes were changes in mean best-corrected visual acuity (BCVA) and central retinal thickness (CRT) from baseline to the third month. The secondary outcomes included the incidence of intraocular inflammation (IOI), proportion of patients with subretinal and intraretinal fluid (SRF and IRF), and change in pigment epithelial detachment (PED) height from baseline to the third month. The significance level was considered as p < .05 in all tests. A total of 38 patients (40 eyes) with a mean (±SD) age of 76.3 (±10.84) years were included. The baseline BCVA was 0.92±0.64 logMAR, and the CRT and PED height were 329.0±171.18 and 189.8±114.94 um, respectively. The patients had a significant reduction in CRT and resolution of IRF and SRF from baseline to the third month. There were numerical improvements in mean BCVA and PED height, but they were not significant. The percentages of achieving at least 0.1, 0.2, and 0.3 logMAR (equivalent to 5, 10, 15 ETDRS letters) visual gain were 50%, 37.5%, and 30%, respectively, during the first 3 months of follow-up. No IOI occurred in these patients. This study demonstrated that brolucizumab had good short-term structural and functional efficacy in recalcitrant nAMD patients.

RESUMEN

INTRODUCTION: Patients with advanced age-related macular degeneration (AMD) frequently experience loss to follow-up (LTFU), heightening the risk of vision loss from treatment delays. This study aimed to identify factors contributing to LTFU in patients with advanced AMD and assess the effectiveness of telephone-based outreach in reconnecting them with eye care. METHODS: A custom reporting tool identified patients with advanced AMD who had not returned for eye care between 31 October 2021 and 1 November 2022. Potentially LTFU patients were enrolled in a telephone outreach programme conducted by a telehealth extender to encourage their return for care. Linear regression analysis identified factors associated with being LTFU and likelihood of accepting care post-outreach. RESULTS: Out of 1269 patients with advanced AMD, 105 (8.3%) did not return for recommended eye care. Patients LTFU were generally older (89.2 ± 8.9 years vs. 87.2 ± 8.5 years, p = 0.02) and lived farther from the clinic (25 ± 43 miles vs. 17 ± 30 miles, p = 0.009). They also had a higher rate of advanced dry AMD (26.7% vs. 18.5%, p = 0.04) and experienced worse vision in both their better-seeing (0.683 logMAR vs. 0.566 logMAR, p = 0.03) and worse-seeing (1.388 logMAR vs. 1.235 logMAR, p = 0.04) eyes. Outreach by a telehealth extender reached 62 patients (59%), 43 through family members or healthcare proxies. Half of the cases where a proxy was contacted revealed that the patient in question had died. Among those contacted directly, one third expressed willingness to resume eye care (20 patients), with 11 scheduling appointments (55%). Despite only two patients returning for in-person eye care through the intervention, the LTFU rate halved to 4.4% by accounting for those patients who no longer needed eye care at the practice. CONCLUSIONS: There is a substantial risk that older patients with advanced AMD will become LTFU. Targeted telephone outreach can provide a pathway for vulnerable patients to return to care.

RESUMEN

PURPOSE: The aim of this study was to compare the responses of type 1 and type 2 macular neovascularizations (MNV) caused by neovascular type age-related macular degeneration (n-AMD) to intravitreal anti-vascular endothelial growth factor (VEGF) treatments using quantitative parameters determined by optical coherence tomography (OCT). Additionally, it was also intended to assess the connections between these quantitative parameters and changes in best-corrected visual acuity (BCVA) and the number of intravitreal anti-VEGF injections required within a year. MATERIALS AND METHODS: In our retrospective and observational study, the data of 90 eyes of 90 patients diagnosed with n-AMD and treated with intravitreal anti-VEGF with the "Pro re nata" method were evaluated. Subtypes of existing MNVs were distinguished with previously taken optical coherence tomography angiography (OCTA) images. In spectral domain OCT examinations, central macular thickness (CMT) and central macular volume (CMV) values were recorded at baseline and 12th month. The number of intravitreal anti-VEGF injections during the 12 month follow-up period was also recorded for each patient. Obtained data were compared between MNV types. RESULTS: Of the n-AMD cases examined in the study, 56.66% had type 1 MNV and 43.34% had type 2 MNV. The mean baseline BCVA logMAR values in eyes with type 2 MNV (1.15 ± 0.43) were higher than those observed in eyes with type 1 MNV (0.76 ± 0.42) (p = 0.001). Similarly, mean baseline CMT and CMV values in eyes with type 2 MNV were higher than those observed in eyes with type 1 MNV (respectively 424.89 ± 49.46 µm vs. 341.39 ± 37.06 µm; 9.17 ± 0.89 µm3 vs. 8.49 ± 0.53 µm3; p < 0.05). After 12 months of treatment, logMAR values of BCVA (0.86 ± 0.42) in subjects with type 2 MNV were higher than those in subjects with type 1 MNV (0.57 ± 0.37) (p = 0.001). Mean CMT and CMV values at 12th month in subjects with type 2 MNV (379.11 ± 46.36 µm and 8.66 ± 0.79 µm3, respectively) were observed to be higher than those with type 1 MNV (296.95 ± 33.96 µm and 8.01 ± 0.52 mm3, respectively) (p < 0.05). In type 2 MNVs, positive correlations were observed between both baseline and 12th month BCVA logMAR values and baseline CMV (p < 0.05). Similarly, in type 2 MNVs, a positive correlation was observed between 12th month BCVA logMAR values and 12th month CMV (p < 0.05). The total number of intravitreal anti-VEGF injections at 12 months was similar in both groups (p = 0.851). CONCLUSION: In this study, in which we performed a subtype analysis of MNV cases, we observed that the visual function was worse at the beginning and the end of the 12th month, and the CMT and CMV values were higher in the type 2 MNV group compared to the type 1 MNV cases. In addition, we found significant correlations between BCVA logMAR values and CMV values in type 2 MNV cases. In the follow-up of these cases, CMT, which is a more widely used quantitative method, and CMV, which is a newer OCT measurement parameter, may be more useful in patient follow-up and evaluation of treatment efficacy, especially for type 2 MNV cases.

RESUMEN

Purpose: To explore the occurrence of macular atrophy (MA) in eyes with age-related macular degeneration (AMD)-associated Type 3 macular neovascularization (MNV) treated with anti-vascular endothelial growth factor (anti-VEGF) therapy. Importantly, we aimed at describing the existence of separate pathways leading to MA. Methods: We analyzed 41 participants (41 eyes) with treatment-naïve Type 3 MNV who were followed up for a duration of 12 months after beginning the anti-VEGF therapy. At the one-year follow-up visit, optical coherence tomography (OCT) scans were reviewed for the presence of MA. MA regions of interest (ROIs) were selected and traced back to their original dominant baseline lesion (i.e., precursor) through previous serially captured OCT scans. Baseline lesions included precursors associated with the development and exudation of MNV and causes external to the neovascularization itself. Results: At the one-year follow-up visit, MA was graded to be present in 38 (92.7%) out of 41 eyes. These 78 MA ROIs were divided into two subgroups according to the precursor lesion, yielding a group of 53 MA lesions with precursors associated with the development and exudation of MNV (i.e., MA caused by physical harm from Type 3 neovessels, collapse of a serous pigment epithelium detachment, and fibrosis) and 25 MA regions with precursors external to the neovascularization itself (i.e., MA caused by drusen or subretinal drusenoid deposits). Conclusions: Eyes with Type 3 MNV are commonly complicated by MA and precursors of MA include causes associated with the development and exudation of MNV, as well as lesions unrelated to the neovascularization process itself.

RESUMEN

PURPOSE: To investigate the current prevalence and causes of moderate and severe visual impairment (MSVI) and blindness in elderly people in suburban Shanghai, China. METHODS: A cross-sectional study based on the population was conducted, which involved 5846 individuals (11,692 eyes) aged 65 years or older. Thorough eye examinations were performed to assess the prevalence and leading factors of MSVI (BCVA <20/63 to ≥20/400) and blindness (BCVA <20/400). RESULTS: The standardized prevalence of bilateral MSVI and blindness was 3.3% and 0.6%, correspondingly. The standardized prevalence of monocular MSVI and blindness was 7.4% and 2.0%, correspondingly. Cataract (47.9% and 20.7%, correspondingly) and myopic macular degeneration (MMD, 25.7% and 31.1%, correspondingly) were the principal causes of bilateral MSVI and blindness. As for monocular MSVI, the primary causes were cataract (39.4%), age-related macular degeneration (AMD, 16.6%), and MMD (16.6%). The primary causes of monocular blindness were other posterior segment eye diseases (30.1%) and MMD (14.2%). In adults aged 65-74 years, MMD was the foremost factor causing bilateral vision impairment. Conversely, cataract was identified as the primary cause of bilateral and monocular vision impairment among adults aged ≥ 75 years. AMD accounts for a significant proportion of individuals across all age groups. CONCLUSIONS: The significant prevalence of MSVI and blindness among Chinese adults represents a critical public health issue. In addition to cataract, the vision impairment caused by MMD and AMD become an important issue in the elderly Chinese people.

RESUMEN

INTRODUCTION: Sickle cell disease (SCD) is one of the most common genetic disorders in the UK, with over 15 000 people affected. Proliferative sickle cell retinopathy (SCR) is a well-described complication of SCD and can result in significant sight loss, although the prevalence in the UK is not currently known. There are currently no national screening guidelines for SCR, with wide variations in the management of the condition across the UK. METHODS AND ANALYSIS: The Sickle Eye Project is an epidemiological, cross-sectional, non-interventional study to determine the prevalence of visual impairment due to SCR and/or maculopathy in the UK. Haematologists in at least 16 geographically dispersed hospitals in the UK linked to participating eye clinics will offer study participation to consecutive patients meeting the inclusion criteria attending the sickle cell clinic. The following study procedures will be performed: (a) best corrected visual acuity with habitual correction and pinhole, (b) dilated slit lamp biomicroscopy and funduscopy, (c) optical coherence tomography (OCT), (d) OCT angiography where available, (e) ultrawide fundus photography, (f) National Eye Institute Visual Function Questionnaire-25 and (g) acceptability of retinal screening questionnaire. The primary outcome is the proportion of people with SCD with visual impairment defined as logarithm of the minimum angle of resolution ≥0.3 in at least one eye. Secondary outcomes include the prevalence of each stage of SCR and presence of maculopathy by age and genotype; correlation of stage of SCR and maculopathy to severity of SCD; the impact of SCR and presence of maculopathy on vision-related quality of life; and the acceptability to patients of routine retinal imaging for SCR and maculopathy. ETHICS AND DISSEMINATION: Ethical approval was obtained from the South Central-Oxford A Research Ethics Committee (REC 23/SC/0363). Findings will be reported through academic journals in ophthalmology and haematology.

RESUMEN

Decades of studies on age-related macular degeneration (AMD), cardiovascular disease and stroke have not found consistent associations between AMD and systemic vascular disease. This study suggests that there is in fact no general relationship, but instead a strong, specific association between only the subretinal drusenoid deposit (SDD) phenotype of AMD on retinal imaging and certain co-existent vascular diseases that are high risk for compromised cardiac output or internal carotid artery stenosis. Future screening initiatives for these high -risk vascular diseases (HRVDs) with fast, inexpensive retinal imaging could make a significant contribution to public health and save lives. Likewise, screening patients with known HRVDs for unrecognized AMD of the SDD form could enable needed treatment and save vision.

RESUMEN

PURPOSE: To evaluate the effect of age-related macular degeneration (AMD) on vision-related quality of life (VRQOL) and depression levels. METHODS: This cross-sectional study included 143 patients who are being followed up with a diagnosis of AMD. The Turkish versions of the National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25) and Geriatric Depression Scale-15 (GDS-15) were directed to the patients. The questionnaire results were analyzed based on the severity, treatment procedures for AMD, and sociodemographic characteristics of patients. RESULTS: The subscale scores obtained from the NEI VFQ-25 ranged from 47.54 for "near activities" to 84.02 for "color vision." Of the patients, 59.4% (85/143) were compatible with depression according to the GDS-15 questionnaire. There was no significant difference in the NEI VFQ-25 subscale scores between the gender groups (P > 0.05), whereas females were statistically significantly more depressive than males (P < 0.05). There were no significant differences between the injection (anti-vascular endothelial growth factors [anti-VEGF]) group and the non-injection group in terms of subscales of the NEI VFQ-25 questionnaire (P > 0.05). The depression ratio in the non-injected group was statistically significantly higher (P < 0.05). CONCLUSION: According to the present study, the association between depression and AMD is a fact that should be highlighted. Patients with depression had lower scores on the quality of life (QOL) test. Previous intravitreal injection did not affect NEI VFQ-25 scores. Female patients with AMD had higher rates of depression and lower visual acuity levels.

RESUMEN

BACKGROUND: The aim of this review was to systematically summarize the current knowledge on type 3 macular neovascularization (MNV3) in age-related macular degeneration (AMD). SUMMARY: Recent histopathologic and multimodal imaging findings led to the consensus definition of the new term "type 3 macular neovascularization" in AMD. MNV3 originates in the deep vascular plexus as a neovascular process without connection with the retinal pigment epithelium in the initial stages. This type has numerous clinical and pathomorphologic features that separate it from the other two types of MNV in AMD. Besides, its frequency appears to be higher than previously thought. In optical coherence tomography (OCT), MNV3 can be classified into stages 1-3. Hyperreflective foci in the outer retina possibly represent a precursor lesion. In addition, MNV3 is characterized by a strong association with reticular pseudodrusen, a high rate of bilaterality, close associations with advanced age and arterial hypertension, decreased choroidal thickness, and decreased choriocapillaris flow signals. Data from latest anti-vascular endothelial growth factor studies in MNV3 suggest that the OCT biomarkers in intraretinal and subretinal fluids should be interpreted differently than in the other types. Additionally, data from MNV3 eyes should be analyzed separately, allowing optimal type-specific treatment strategies in the future. KEY MESSAGES: This review highlights the need for accurate characterization of neovascular AMD lesions and an MNV type-specific approach, particularly for MNV3.

RESUMEN

Age-related macular degeneration (AMD) is a leading cause of blindness featuring pathogenic neovascularization of the choroidal vasculature (CNV). Although systemic immunity plays a role in AMD, the ocular signals that recruit and activate immune cells remain poorly defined. Using single-cell RNA sequencing, we prospectively profile peripheral blood mononuclear cells from 65 individuals including AMD and controls, which we integrate with existing choroid data. We generate a network of choroid-peripheral immune interactions dysregulated in AMD, including known AMD-relevant gene vascular endothelial growth factor (VEGF) receptor 2. Additionally, we find CYR61 is upregulated in choroidal veins and may signal to circulating monocytes. In mice, we validate that CYR61 is abundant in endothelial cells within CNV lesions neighboring monocyte-derived macrophages. Mechanistically, CYR61 activates macrophage anti-angiogenic gene expression, and ocular Cyr61 knockdown increases murine CNV size, indicating CYR61 inhibits CNV. This study highlights the potential of multi-tissue human datasets to identify disease-relevant and potentially therapeutically modifiable targets.

RESUMEN

BACKGROUND: Double optic disc pit maculopathy is a rare entity. It can be difficult to manage because of excessive leakage and chronic maculopathy. PURPOSE: To describe surgical management in a case of double optic disc pits with maculopathy. SYNOPSIS: A 42-year-old male presented with double optic disc pits with macular detachment in the left eye. The best-corrected visual acuity (BCVA) was 20/60, N12. Preoperative OCT showed the presence of two disc pits. The macular region had large retinoschisis and subretinal fluid (SRF) with a central foveal thickness of 879 microns and loss of the ellipsoid zone. A shallow communication from the temporal aspect of the disc to the submacular area was also noted. Among the options of observation, laser photocoagulation, and surgery, the patient opted for surgical management. SURGICAL TECHNIQUE: A standard-3 port 23-gauge pars plana vitrectomy was done. After staining the ILM with brilliant blue, ILM peeling was done with the help of forceps and Finesse loop. ILM flaps were inverted over to cover the optic disc pits and sealed with a drop of fibrin glue. Next, 20% SF6 gas was used for tamponade. Pre- and post-surgery parameters such as visual acuity and OCT were evaluated. POSTOPERATIVE EVALUATION: After 6 weeks, left eye BCVA was 20/40 with OCT showing reduced SRF and reduced intraretinal schisis with a foveal thickness of 546 microns. At 3 months of follow-up, the vision in the left eye had improved to 20/30 with further reduction in the retinoschisis and foveal thickness of 482 microns. HIGHLIGHTS: In this interesting case, we demonstrate a unique way of sealing the defect surgically by vitrectomy and inverted ILM flap with fibrin glue over the disc pits. Despite sealing the maculopathy is slow to resolve. VIDEO LINK: https://youtu.be/s9nY5UPe1s4.

RESUMEN

Importance: Individuals with high myopia younger than 18 years are at relatively high risk of progressively worsening myopic maculopathy. Additional studies are needed to investigate the progression of myopic maculopathy in this age group, as well as the risk factors associated with progression. Objective: To investigate the 4-year progression of myopic maculopathy in children and adolescents with high myopia, and to explore potential risk factors. Design, Setting, and Participants: This hospital-based observational study with 4-year follow-up included a total of 548 high myopic eyes (spherical power -6.00 or less diopters) of 274 participants aged 7 to 17 years. Participants underwent comprehensive ophthalmic examination at baseline and 4-year follow-up. Myopic maculopathy was accessed by the International Photographic Classification and Grading System. The data analysis was performed from August 1 to 15, 2023. Main Outcomes and Measures: The progression of myopic maculopathy progression over 4 years and associated risk factors. Results: The 4-year progression of myopic maculopathy was found in 67 of 548 eyes (12.2%) of 274 participants (138 girls [50.4%] at baseline and 4-year follow-up) with 88 lesion changes, including new signs of the tessellated fundus in 16 eyes (18.2%), diffuse atrophy in 12 eyes (13.6%), patchy atrophy in 2 eyes (2.3%), lacquer cracks in 9 eyes (10.2%), and enlargement of diffuse atrophy in 49 eyes (55.7%). By multivariable analysis, worse best-corrected visual acuity (odds ratio [OR], 6.68; 95% CI, 1.15-38.99; P = .04), longer axial length (AL) (OR, 1.73; 95% CI, 1.34-2.24; P < .001), faster AL elongation (OR, 302.83; 95% CI, 28.61-3205.64; P < .001), and more severe myopic maculopathy (diffuse atrophy; OR, 4.52; 95% CI, 1.98-10.30; P < .001 and patchy atrophy; OR, 3.82; 95% CI, 1.66-8.80; P = .002) were associated with myopic maculopathy progression. Conclusions and Relevance: In this observational study, the progression of myopic maculopathy was observed in approximately 12% of pediatric high myopes for 4 years. The major type of progression was the enlargement of diffuse atrophy. Risk factors for myopic maculopathy progression were worse best-corrected visual acuity, longer AL, faster AL elongation, and more severe myopic maculopathy. These findings support consideration of follow-up in these individuals and trying to identify those at higher risk for progression.

RESUMEN

PURPOSE: To determine prevalence of anisomyopia (axial length (AL) difference ≥2.5 mm) among high myopes ((HMs), defined by spherical equivalent of ≤6.0 diopters or AL ≥ 26.5 mm). To characterise the shorter anisomyopic eye (SAE) and evaluate if pathologic myopia (PM) in the longer anisomyopic eye (LAE) was associated with increased risk of PM in the SAE. METHODS: 1168 HMs were recruited from Singapore National Eye Centre clinic for this cross-sectional study. Biometry, fundus photography and swept-source optical coherence tomography were performed. Patients with high axial anisomyopia were identified. Structural characteristics and presence of PM were described. Stepwise multivariate regression explored associations between PM in the LAE and pathology in the SAE, controlling for confounding variables. RESULTS: Prevalence of anisomyopia was 15.8% (184 of 1168 patients). Anisomyopic patients (age 65.8±13.5 years) had mean AL of 30.6±2.0 mm and 26.2±2.3 mm in the LAE and SAE, respectively. 52.7% of SAEs had AL < 26.5 mm. Prevalence of myopic macular degeneration, macula-involving posterior staphyloma (PS), myopic traction maculopathy (MTM) and myopic choroidal neovascularisation (mCNV) in the SAE was 52.2%, 36.5%, 13.0% and 8.2%, respectively. Macular hole in the LAE was associated with increased risk of MTM in the SAE (OR=4.88, p=0.01). mCNV in the LAE was associated with mCNV in the SAE (OR=3.57, p=0.02). PS in the LAE was associated with PS in the SAE (OR=4.03, p<0.001). CONCLUSIONS: Even when controlled for AL, PM complications in the LAE predict similar PM complications in the SAE. Patients with high axial anisometropia with PM in the LAE should be monitored carefully for complications in the SAE.

RESUMEN

Obesity is known to be associated with numerous ocular manifestations, including but not limited to, diabetic retinopathy (DR), age-related macular degeneration (AMD), cataracts, glaucoma, and dry eye disease. This review aims to provide an overview of the ophthalmological findings in obesity. A literature search was conducted using PubMed and Cochrane databases for studies describing randomized clinical trials, meta-analyses, systematic reviews, and observational studies published from 1 January 2017 to 1 April 2023. The search terms used included relevant keywords such as 'obesity', 'body mass index', 'waist-to-hip ratio', 'bariatric', 'ophthalmology', 'eye disease', 'myopia', 'retinopathy', 'glaucoma', and 'cataract'. This literature search was performed on 1 April 2023. Obesity is associated with increased risk of developing DR, a sight-threatening complication of diabetes mellitus. Similarly, obesity has been shown to increase risk of AMD, cataracts, glaucoma, and ocular surface disease. Multiple mechanisms linking obesity to ophthalmic disease have been proposed. Adipose tissue produces various inflammatory cytokines that can affect ocular tissues, leading to disease progression. Additionally, obesity is associated with systemic metabolic changes that can influence ocular health. Bariatric surgery has been shown to be protective against development of ophthalmic disease. Obesity is a significant risk factor for several ophthalmological diseases. Healthcare providers should encourage weight loss in patients with overweight or obesity to prevent or delay the onset of ocular complications. Further research is needed to better understand the underlying mechanisms of this association, and to identify effective strategies for preventing or managing ophthalmic disease in patients with obesity.

RESUMEN

BACKGROUND: This study aimed to assess the vision-related quality of life (VRQol) of patients with age-related macular degeneration (AMD) and to evaluate VRQol according to different types of AMD. METHODS: In this small-scale, single-center, prospective investigation, patients with AMD and subjects without any signs of macular disease were asked to complete the NEI-VFQ-39. A total of 159 subjects were included and grouped according to the type of AMD as follows: 40 patients with dry AMD in both eyes (DD), 40 patients with exudative AMD in one eye (DE), 41 patients with exudative AMD in both eyes (EE), and 38 subjects without any signs of macular disease, as a control group (CG). RESULTS: The average age of the participants was 76 ± 7 years, and 44% were male. Most participants were retired (22.4%), and 75% of patients were initially diagnosed by their ophthalmologist. All the AMD groups had significantly worse overall VRQol than the CG. For general vision, near vision, mental health, and role difficulties, all the AMD groups had significantly lower scores than the CG. For distance vision, color vision, peripheral vision, driving difficulties, dependency, and social functioning, only patients in the EE and DE groups had significantly worse scores than the CG. The type of retinal fluid in patients with exudative AMD had no effect on overall VRQol; however, we found that the presence of pigment epithelial detachment could be associated with more role difficulties, such as completing work or working long hours. CONCLUSION: All types of AMD had a negative effect on vision-related quality of life. This effect was significantly more pronounced in patients with exudative AMD in at least one eye. However, the type of retinal fluid in patients with exudative AMD had no influence on their overall vision-related quality of life.

RESUMEN

PURPOSE: Our aim was to evaluate whether patients with age-related macular degeneration (AMD) and cooccurrent amblyopia are more likely to have diseases diagnosed on both the ipsilateral and the contralateral side in a large Austrian database. DESIGN: Retrospective cross-sectional study. METHODS: Setting: Institutional practice. PATIENT POPULATION: Medical records of all patients who visited the Department of Ophthalmology of the Medical University of Graz between December 1996 and June 2021 were searched for the co-occurrence of AMD and amblyopia. MAIN OUTCOME MEASURES: Data from patients with AMD diagnosed on 1 eye side were used for further analysis. Spectral-domain optical coherence tomography images were analyzed to confirm the lateral asymmetry of AMD. RESULTS: A total of 327,443 patients were screened for the co-occurrence of AMD and amblyopia. Of them, 8742 patients had AMD diagnosed on 1 eye side and 5051 patients had unilateral amblyopia. In total, 163 patients were found to have AMD diagnosed on 1 side and unilateral amblyopia in combination. Of these, 126 patients had AMD and amblyopia on contralateral sides and 37 had AMD and amblyopia on the ipsilateral side (P < .001). CONCLUSIONS: Less amblyopic patients had AMD diagnosed on the amblyopic eye compared with the nonamblyopic eye. In cases of lateral asymmetry, the nonamblyopic eye is more likely to have the more advanced form of AMD.

RESUMEN

PURPOSE: To analyze anatomic and functional response to intravitreal brolucizumab in age-related macular degeneration recalcitrant to previous intravitreal anti-VEGF therapies. METHODS: In this monocentric, one arm, retrospective study, eyes affected by neovascular age-related macular degeneration (nAMD) resistant to other intravitreally injected anti-vascular endothelial growth factor inhibitors were switched to intravitreal brolucizumab. All patients underwent ophthalmological examinations at baseline and in regular follow-up intervals. Best registered visual acuity (BRVA), Goldmann tonometry, intraocular pressure (IOP), central retinal thickness (CRT) and pigment epithelial detachment (PED) characteristics were analyzed at initiation of anti-VEGF treatment, at treatment switch, and at the end of brolucizumab loading phase. RESULTS: The study included 20 eyes of 18 consecutively treated patients (age: 77 ± 6 years). All eyes had macular neovascularization with PED. Previous treatments included intravitreal aflibercept, bevacizumab, and ranibizumab and had not resulted in a significant improvement in BRVA (0.5 ± 0.5 logMAR vs 0.5 ± 0.6 logMAR) or mean CRT (320 ± 60 µm vs 313 ± 83 µm) up to treatment switch to brolucizumab. At the end of the brolucizumab loading phase, there was significant improvement for both BRVA (0.3 ± 0.2 logMAR, P < 0.05) and CRT (264 ± 55 µm, P < 0.05). Under previous anti-VEGF therapy, there was a significant increase/deterioration in both PED area (2.68 mm2 to 5.18 mm2, P < 0.05) and PED volume (0.39 mm3 to 1.07 mm3, P < 0.05); however, both parameters improved after switching to brolucizumab (3.81 mm2 and 0.37 mm3, P < 0.05). CONCLUSION: Our results suggest a favourable anatomical and visual response after treatment switch to brolucizumab in patients with nAMD refractory to previous anti-VEGF agents.
