Emotional and physical experiences of people with neovascular age-related macular degeneration during the injection process in Germany: a qualitative study.

OBJECTIVES: In order to better understand the continued barriers to the provision of vascular endothelial inhibitor therapy, this study aims to investigate patients' experiences with neovascular age-related macular degeneration (nvAMD) in Germany during the injection process and how they deal with it. DESIGN AND PARTICIPANTS: This analysis is part of the qualitative arm of a wider mixed-methods study. We recruited participants all over Germany via ophthalmologists, eye clinics, general practitioners, care bases and support groups between June 2018 and December 2020 and selected a subsample of study participants with nvAMD who were either undergoing or had previously undergone vascular endothelial growth factor inhibitor therapy. We conducted narrative, semistructured, face-to-face interviews at the participants' homes, which were audio-recorded. The interviews were thematically analysed. RESULTS: Twenty-two participants were included in this analysis. Experiencing neovascular macular degeneration was dominated by the injection experience. Study participants perceived the treatment with vascular endothelial inhibitor injections as uncomfortable, and they described undergoing varying levels of anxiety during the whole injection process. After some years of receiving multiple injections, the pain and not experiencing any positive effects made participants with significant vision loss want to discontinue therapy. Furthermore, they narrated negative injection experiences in association with their interactions with medical staff and doctors. CONCLUSION: Although time in the medical setting is limited, efficient and good doctor-patient relationships seem crucial for satisfying care experiences. A respectful and humane relationship may be one key to achieving treatment adherence.

Prevalence and risk factors for depressive symptoms in patients with neovascular age-related macular degeneration who present for anti-VEGF therapy.

PURPOSE: To examine the prevalence and risk factors for depressive symptoms in patients with neovascular age-related macular degeneration (nAMD) presenting for anti-vascular endothelial growth factor (anti-VEGF) therapy. METHODS: In a clinic-based cohort of 547 patients with nAMD who presented for treatment, the Centre of Epidemiological Studies Depression 10-point scale (CES-D-10) and Mental Health Index (MHI) component of the 36-item Short Form Survey were administered to assess for the presence of depressive symptoms. Logistic regression analyses were used to calculate odds ratios and 95% confidence intervals for factors associated with an increased likelihood of depressive symptoms. RESULTS: The prevalence of depressive symptoms was 42.04% and 31.78% as per the CES-D-10 and MHI scales, respectively. Poor self-rated health (SRH) is associated with increased odds of depressive symptoms [multivariable-adjusted OR: 3.00 (95% CI 1.90-4.73) for CES-D-10; OR: 2.67 (95% CI 1.67-4.28) for MHI]. Impaired activities of daily living (ADLs) [multivariable-adjusted OR: 2.62 (95% CI 1.56-4.38) for CES-D-10; OR: 3.59 (95% CI 2.10-6.15) for MHI] and a visual function score within the two lowest quartiles were also associated with increased odds of depressive symptoms using both scales. CONCLUSION: A high prevalence of depressive symptoms was observed among nAMD patients presenting for treatment. Poorer SRH, ADL impairment and reduced visual function were associated with increased odds of depressive symptoms.

Contrast sensitivity and binocular reading speed best correlating with near distance vision-related quality of life in bilateral nAMD.

PURPOSE: Bilateral neovascular age-related macular degeneration (nAMD) causes difficulties in daily life, especially with regard to near-vision tasks, despite well preserved Early Treatment of Diabetic Retinopathy Study (ETDRS) best corrected visual acuity (BCVA) at distance. Therefore, alternative visual function measures were evaluated in terms of their correlation with vision-related quality of life scores (QoL). METHODS: A prospective cross-sectional pilot study including patients with a diagnosis of bilateral nAMD having lesions within the central 1 mm ETDRS grid subfield. Standardised testing included a vision-related QoL assessment (NEI-VFQ25), best corrected visual acuity (BCVA), low luminance visual acuity (LLVA), Radner maximum reading speed and Pelli-Robson contrast sensitivity (CS). RESULTS: N = 54. The mean better eye (range) BCVA was 79 (55-96) letters, median (range) LLVA 79.5 (58-97) letters and median (range) CS 1.35 (0-1.65) log units. Mean binocular maximum reading speed was 117.33 ± 28.42 wpm. The best correlations with the near subscale score were found for CS followed by binocular maximum reading speed (r = 0.59, p = 0.0001; r = 0.36, p = 0.008, respectively). A weaker correlation was observed for the BCVA in the better eye (r = 0.33, p = 0.02). The correlation between the NEI-VFQ25 distance subscale and BCVA was weaker (r = 0.37, p = 0.005) than the correlations with CS (r = 0.67, p = 0.0001) and LLVA (r = 0.40, p = 0.003). CONCLUSIONS: For patients with a bilateral centre-involving nAMD, the best correlation with near QoL was the better eye CS followed by maximum binocular reading speed. These measures could be valuable in quantifying vision-related QoL outcomes in AMD clinical trials.

Feelings, preoperative anxiety, and need for information in patients undergoing intravitreal injections.

PURPOSE: To assess feelings, preoperative anxiety, and need for information in patients undergoing intravitreal injections (IVI). METHODS: An observational cross-sectional study was conducted in our tertiary university care center between December 2017 and December 2018. Consecutive patients undergoing IVI were included. A paper survey was completed before and after IVI to assess patient experience. Preoperative anxiety and need for information were assessed using the Amsterdam Preoperative Anxiety Information Scale (APAIS) score. RESULTS: Hundred patients with a median age of 76.5 years (42-95, SD = 10.1) were included. Median best-corrected visual acuity (BCVA) in both eyes was 0.4 logMAR. Main IVI indications were wet age-related macular degeneration (n = 58), diabetic macular edema (n = 19), and venous occlusion (n = 16). The IVI most unpleasant steps were as follows: using an eyelid retractor, needle entry, changing of physician from one IVI to another, the pre-IVI waiting time, and the high number of IVI required for disease control. Preoperative anxiety (APAIS score ≥ 11) was correlated in the multivariate analysis with the need for information (p = 0.004), changing of ophthalmologist between different IVI sessions (p = 0.006), and pain expected before the IVI (p = 0.010). The need for information (APAIS score ≥ 5) was only associated with the preoperative anxiety in the multivariate analysis (p = 0.001). CONCLUSION: Preoperative anxiety and need for information are common in patients undergoing IVI even after many IVI. Being injected by different practitioners was strongly correlated with preoperative anxiety and should be avoided as much as possible. Better educational and information programs are needed.

Vision-related quality of life in Japanese patients with wet age-related macular degeneration treated with intravitreal aflibercept in a real-world setting.

PURPOSE: To evaluate vision-related quality of life (QoL) in wet age-related macular degeneration (wAMD) patients receiving intravitreal aflibercept (IVT-AFL). STUDY DESIGN: Prospective, observational Japanese postmarketing surveillance study. METHODS: All decisions were made by the treating physician. QoL was assessed using the 25-item National Eye Institute-Visual Functioning Questionnaire (NEI-VFQ-25) composite score administered at baseline, 6 months, and 12 months (primary assessment). Secondary assessments included NEI-VFQ-25 subscale scores, resource use, and best-corrected visual acuity (BCVA; logarithm of the minimum angle of resolution [logMAR]). RESULTS: In total, 576 patients (baseline), 555 patients (6 months), and 446 patients (12 months) were included. The mean (SD) number of IVT-AFL injections was 3.5 (1.2) at 6 months and 4.6 (2.2) at 12 months. The mean (SD) improvement from baseline in the NEI-VFQ-25 composite score was 3.1 (11.1) at 6 months and 2.7 (12.3) at 12 months (P < .0001). For the NEI-VFQ-25 subscale scores, the mean change was ≥ 4 (minimally important difference) for general vision, near vision, and mental health at 6 months, and for general vision and mental health at 12 months (all P < .0001). A significant improvement from baseline was found in mean BCVA (logMAR) at 6 months (-0.1) and 12 months (-0.1) (P < .0001). The mean change from baseline in the NEI-VFQ-25 scores was greatest in patients with improved BCVA (gain of ≤ -0.3 logMAR units or ≥ 15 letters) after treatment. CONCLUSION: IVT-AFL was associated with significant improvements in QoL and visual acuity in Japanese patients with wAMD in a real-world setting.

The effect of non-neovascular age-related macular degeneration on face recognition performance.

PURPOSE: There is a well-established research base surrounding face recognition in patients with age-related macular degeneration (AMD). However, much of this existing research does not differentiate between results obtained for 'wet' AMD and 'dry' AMD. Here, we test the hypothesis that face recognition performance is worse in patients with dry AMD compared with visually healthy peers. METHODS: Patients (>60 years of age, logMAR binocular visual acuity 0.7 or better) with dry AMD of varying severity and visually healthy age-related peers (controls) completed a modified version of the Cambridge Face Memory Test (CFMT). Percentage of correctly identified faces was used as an outcome measure for performance for each participant. A 90% normative reference limit was generated from the distribution of CFMT scores recorded in the visually healthy controls. Scores for AMD participants were then specifically compared to this limit, and comparisons between average scores in the AMD severity groups were investigated. RESULTS: Thirty patients (median [interquartile range] age of 76 [70, 79] years) and 34 controls (median age of 70 [64, 75] years) were examined. Four, seventeen and nine patients were classified as having early, intermediate and late AMD (geographic atrophy) respectively. Five (17%) patients recorded a face recognition performance worse than the 90% limit (Fisher's exact test, p = 0.46) set by controls; four of these had geographic atrophy. Patients with geographic atrophy identified fewer faces on average (±SD) (61% ± 22%) than those with early and intermediate AMD (75 ± 11%) and controls (74% ± 11%). CONCLUSIONS: People with dry AMD may not suffer from problems with face recognition until the disease is in its later stages; those with late AMD (geographic atrophy) are likely to have difficulty recognising faces. The results from this study should influence the management and expectations of patients with dry AMD in both community practice and hospital clinics.

Influence of new societal factors on neovascular age-related macular degeneration outcomes.

BACKGROUND: To assess the impact of unstudied societal factors for neovascular age-related macular degeneration (nAMD) on functional outcomes after anti-VEGFs. METHODS: Charts of 94 nAMD patients treated in the Monticelli-Paradis Centre, Marseille, France, were reviewed. Phone interviews were conducted to assess societal factors, including transportation, living status, daily reading and social security scheme (SSS). Primary outcome was the impact of family support and disease burden on functional improvement in nAMD. RESULTS: Between baseline and month 24 (M24), 42.4% of the variability in best-corrected visual acuity (BCVA) was explained by the cumulative effect of the following societal factors: intermittent out-patient follow-up, marital status, daily reading, transportation type, commuting time. No isolated societal factor significantly correlated with ETDRS BCVA severity at M24. A trend to correlation was observed between the EDTRS score at M24 and the SSS (P = 0.076), economic burden (P = 0.075), time between diagnosis and treatment initiation (P = 0.070). A significant correlation was found for the disease burdensome on the patient (P = 0.034) and low vision rehabilitation (P = 0.014). CONCLUSIONS: Societal factors could influence functional outcomes in nAMD patients treated with anti-VEGFs. They could contribute to the healing process or sustain disease progression.

Exploring factors predicting changes in patients' expectations and psychosocial issues during the course of treatment with intravitreal injections for wet age-related macular degeneration.

PurposePatients with wet age-related macular degeneration (AMD) often require long courses of treatment. We investigate the psychosocial issues that could hinder compliance, including patient expectations of treatment. The aims of this study were to explore the factors related to changes in patient expectations, pain, and anxiety during treatment.Patients and methodsA structured interview was carried out among 50 patients selected from the list attending the AMD unit at the Princess Alexandra Eye Pavilion (PAEP). The interview was based on a questionnaire. Additionally, a visual analogue scale was created as a tool for measuring patient expectations, pain, and anxiety. Data were analysed using multinomial regression analysis.ResultsThere were significantly more patients who had a fall in expectations (P<0.05) during the course of treatment. A fall in expectations was found to be predicted by higher starting expectations (P=0.00001), greater decline in visual acuity (P=0.008), and perceived deterioration of vision after starting treatment (P=0.013). Of the patients, 32% planned to stop attending for further injections. Planning to stop attending was correlated with worse final visual acuity (P=0.026, 95% CI). Pain and anxiety with intravitreal therapy (IVT) was significantly reduced when patients were accompanied to the clinic by a friend or relative (P<0.01) using Pearson's correlation (r=0.597).ConclusionPatients require appropriate counselling at the start of a course of treatment to align expectations with perceived treatment outcomes in order to improve adherence. Additionally, a large minority of patients would consider stopping treatment. Patients' expectations should be assessed at relevant time points along a course of treatment.

Change in vision-related quality of life and influencing factors in Asians receiving treatment for neovascular age-related macular degeneration.

AIM: To assess the change in vision-related quality of life (VRQoL) after treatment for neovascular age-related macular degeneration (nAMD) and factors influencing this change in an Asian population. METHODS: In this longitudinal study, 116 patients (mean age±SD=66.5±9.9 years; 59.5% male) who underwent treatment for nAMD were recruited from a tertiary eye centre in Singapore. Best-corrected visual acuity (BCVA) and the Impact of Vision Impairment (IVI) questionnaire were evaluated at baseline and month 12. We defined three categories of BCVA change in the treated eye: BCVA gain ≥2 lines; no change in BCVA; BCVA loss ≥2 lines. The main outcome measures were the Rasch-derived IVI Reading, Mobility, and Emotional Scores. Multivariable linear regression analyses assessed the influence of sociodemographic, clinical and treatment-related factors on change in VRQoL. RESULTS: Following treatment, mean treated-eye BCVA improved by almost 2 lines (-0.22±0.40 logMAR, p<0.001) and 43% (n=50) patients reported a gain in BCVA of ≥2 lines. Mean±SD scores for Reading, Mobility and Emotional demonstrated positive changes of 0.43±1.73, 0.45±1.54 and 0.66±1.6, respectively (p<0.001 for all). In multivariable models, a ≥2 line improvement in BCVA was independently associated with a 47% (ß=0.20; CI 0.01 to 0.39) increase in Reading Scores, but was not independently associated with Mobility or Emotional Scores. CONCLUSION: Nearly half of patients undergoing treatment for nAMD reported a 2-line improvement in vision which was, in turn, associated with substantial positive increases in Reading Scores. Improvements in Mobility and Emotional Scores appear to be driven by factors other than visual acuity.

Investigation of time to first presentation and extrahospital factors in the treatment of neovascular age-related macular degeneration: a retrospective cross-sectional study.

OBJECTIVES: To assess the time from symptom onset to treatment for neovascular age-related macular degeneration (nvAMD) and to measure the awareness of AMD in Southeast Scotland. DESIGN: Retrospective cross-sectional study. SETTING: Secondary care, Southeast of Scotland. METHODS: Patients treated with intravitreal therapy (IVT) for nvAMD in Southeast Scotland between 2013 and 2015 were identified using a treatment register. Notes were retrospectively reviewed. We measured time from: (A) symptom onset to first presentation at primary care, (B) referral to ophthalmic clinic appointment and (C) ophthalmic clinic appointment to first IVT treatment. To investigate AMD awareness, we performed a cluster random sample survey of patients visiting non-AMD ophthalmic clinics using a previously validated 12-item questionnaire. RESULTS: 195 patients (mean age 78 years) were included in the study. The mean delays between the different stages-A, B and C-were 54.2 (95% CI ±13), 28.2 (95% CI ±4.0) and 31.5 (95% CI ±3.6) days, respectively. There was an additional mean delay of 7.5 (95% CI ±1.6) days when patients were indirectly referred by optometrists via general practitioners (P<0.05). 140 patients (mean age 78) participated in the awareness survey; 62.1% reported being 'aware' of AMD but only 37.3% described AMD symptoms correctly. CONCLUSIONS: There was a significant delay at every step of the nvAMD care pathway. The causes for this were multifactorial and included delays in first presentation to a healthcare provider, referral from primary care and initiation of secondary care treatment. Our data are likely to underestimate prehospital delays as a large number of cases are likely to have undefined symptoms and onset. We also identified suboptimal awareness of AMD which could account for a substantial delay in presentation from symptom onset. These findings highlight the need to address AMD awareness and the need for urgent treatment to prevent avoidable vision loss resulting from nvAMD.

Patient Awareness of Cataract and Age-related Macular Degeneration among the Korean Elderly: A Population-based Study.

PURPOSE: Age-related eye disease is often considered part of natural aging. Lack of awareness of eye conditions can result in missed treatment. We investigated the rates of awareness of cataract and age-related macular degeneration, the most common age-related eye-diseases, and the associated factors among elderly Koreans. METHODS: We identified 7,403 study subjects (≥40 years old) with cataract or age-related macular degeneration based on ophthalmic examination results during the 5th Korean National Health and Nutrition Examination Survey conducted between 2010 and 2012. We assessed whether patients were aware of their eye condition based on a previous diagnosis by a physician. RESULTS: The average awareness rate over the 3-year study period was 23.69% in subjects with cataract and 1.45% in subjects with age-related macular degeneration. Logistic regression analysis showed that patients with cataract were more likely to recognize their condition if they had myopia (odds ratio, 2.08), hyperopia (odds ratio, 1.33), family history of eye disease (odds ratio, 1.44), or a past eye examination (odds ratio, 4.07-29.10). The presence of diabetes mellitus was also a significant predictor of patient awareness of cataract (odds ratio, 1.88). CONCLUSIONS: Poor patient recognition of eye disease among the Korean elderly highlights the seriousness of this potential public health problem in our aging society. Pre-existing eye-related conditions and diabetes were significant predictors of awareness; therefore, patients in frequent contact with their doctors have a greater chance of detecting eye disease.

Tracing the natural course of visual acuity and quality of life in neovascular age-related macular degeneration: a systematic review and quality of life study.

BACKGROUND: Describing the natural course of neovascular age-related macular degeneration (nAMD) is essential in discussing prognosis and treatment options with patients and to support cost-effectiveness studies. METHODS: First, we performed a literature search in PubMed, Embase, and Cochrane. We included randomized clinical trials and prospective observational studies reporting visual acuity (VA) in non-treated patients, 24 studies in total. We integrated VA data using best fit on Lineweaver-Burke plots and modelled with non-linear regression using reciprocal terms. Second, we performed a quality-of-life (QoL) study in nAMD patients. We measured VA with Radner reading charts and QoL with the Health Utilities Index issue 3 (HUI-3) questionnaire in 184 participants. We studied the relation VA-QoL with linear regression. Third, with Monte Carlo simulation, we integrated the VA model from the literature review and the relation VA-QoL from the QoL study. RESULTS: Visual acuity was 0.4 and 0.07 after 5 years in the better-seeing, and worse-seeing eye, respectively. After 4.3 years, VA was <0.5 in the better-seeing eye; <0.3 after 7 years; 0.05 after 17 years. QoL score decreased from 0.6 to 0.45 after 10 years. CONCLUSIONS: The natural course of nAMD in both eyes needs to be considered when informing patients. Visual acuity in the best eye decreases to below 0.5 in 4.3 years. This affects QoL significantly.

Vision-related quality of life: 12-month aflibercept treatment in patients with treatment-resistant neovascular age-related macular degeneration.

PURPOSE: To assess changes in vision-related quality of life (VR-QoL) among patients with treatment-resistant neovascular age-related macular degeneration (nAMD) following intravitreal aflibercept treatment over 48 weeks. METHODS: We conducted a prospective study in which 49 patients with nAMD resistant to anti-vascular endothelial growth factor therapy were switched to intravitreal aflibercept. Patients were treated with three loading doses every 4 weeks followed by injections every 8 weeks, for a total of 48 weeks. Ophthalmic examinations performed at each visit included best-corrected visual acuity (BCVA) and central macular thickness (CMT) measurement. The National Eye Institute Visual Functioning Questionnaire 25 (NEI VFQ-25) was used to assess VR-QoL at baseline and weeks 24 and 48. Changes in NEI VFQ-25 composite and subscale scores were analyzed using paired t tests. The relationship between the change in VR-QoL and changes in BCVA and CMT, and the impact of the better-seeing eye (BSE, defined as the eye reading the greater number of letters at baseline) vs. the worse-seeing eye (WSE, the fellow eye to the BSE) were assessed. RESULTS: Mean NEI VFQ-25 composite scores improved significantly at weeks 24 and 48 compared to baseline (4.5 ± 9.2 and 4.4 ± 11.8, respectively, all p < 0.01). Among subscales, general vision and near and distance activities showed significant improvements at weeks 24 and 48 (all p < 0.05). Improvement in the NEI VFQ-25 composite score was significantly associated with increased BCVA at week 48 (ß coefficient = 0.43, p = 0.029), but not with change in CMT (ß coefficient = -0.007, p = 0.631). There was no association between VR-QoL changes and BSE or WSE. CONCLUSION: Despite previous anti-VEGF treatment in this cohort, overall VR-QoL improved following aflibercept therapy over 48 weeks. This improvement was related to improved vision in treatment eyes regardless of whether they were the BSE or WSE.

The impact of typical neovascular age-related macular degeneration and polypoidal choroidal vasculopathy on vision-related quality of life in Asian patients.

AIMS: To determine the impact of neovascular age-related macular degeneration (nAMD) on vision-related quality of life (VRQoL) in an Asian population. METHODS: In this cross-sectional study, 162 subjects with nAMD from the Asian AMD Phenotyping Study and 105 randomly sampled age-matched and gender-matched controls from the population-based Singapore Chinese Eye Study were recruited. nAMD was categorised as either polypoidal choroidal vasculopathy (PCV) or 'typical' AMD (tAMD). The reading, mobility and emotional well-being subscales of the impact of vision impairment (IVI) scale were validated using Rasch analysis and used as the main outcome measures and collectively referred to as VRQoL. Multivariate linear regression analyses were performed to assess the impact of nAMD overall, and PCV and tAMD subtypes, on the three IVI domains. RESULTS: Of the 162 with nAMD, 103 (63.6%) had PCV and 59 (36.4%) had tAMD. In multivariate models, nAMD overall was independently associated with a 21% reduction in reading (ß=-1.08; CI -1.58 to -0.57); 16% reduction in mobility (ß=-0.74; -1.14 to -0.33) and 44% reduction in emotional well-being (ß=-2.15; -2.83 to -1.47) compared with controls. There were significant VRQoL deficits (p<0.05) associated with both PCV and tAMD; these deficits were similar and not statistically different between the two nAMD subtypes (p>0.05). CONCLUSIONS: Neovascular AMD, including both PCV and tAMD subtypes, has a detrimental impact on VRQoL in Asian subjects independent of level of vision impairment. Interventions to increase reading capacity, enhance mobility and independence and improve mental health outcomes for subjects with neovascular AMD further address the impact of the condition on VRQoL in addition to pharmacological therapies.

Distinguishing between Better and Worse Visual Acuity by Studying the Correlation with Quality of Life in Neovascular Age-Related Macular Degeneration.

PURPOSE: To determine whether there is a level of visual acuity (VA) in neovascular age-related macular degeneration (nAMD) above which the correlation of VA with disease-related quality of life (QoL) is significantly greater than below this level. DESIGN: An observational, cross-sectional study. PARTICIPANTS: A total of 184 patients with nAMD aged at least 50 years were included in the study. METHODS: In face-to-face interviews, we assessed QoL with the Macular Disease-Dependent Quality of Life (MacDQoL) questionnaire. We measured VA with standardized Radner reading charts. We used regression splines analysis with a single hinge point, with the MacDQoL score as the dependent variable and VA as the independent variable. The x-coordinate (VA) of the hinge point was varied and tested with each iteration. A second method of regression splines analysis was also performed, without a preset hinge point. MAIN OUTCOME MEASURES: The primary outcome measure is the cutoff point at or below which VA is associated with significantly less change in QoL than above this cutoff. The linear coefficients below and above the cutoff are defined as change in MacDQoL score per logarithm of the minimum angle of resolution (logMAR) unit of change in VA. RESULTS: With Snellen equivalent VA 0.05 (1.3 logMAR) or worse, the linear coefficient was 0.15. With VA better than 0.05, the linear coefficient was 2.40 (P value of the difference: 0.009). CONCLUSIONS: When VA is above 0.05, there is a stronger and significant relation between VA and QoL. At or below this level, the relation between VA and QoL approaches zero. With better VA, a difference in VA implies a significant difference in QoL. With poorer VA, a difference in VA is unlikely to imply a difference in QoL. Therefore, in treating nAMD, the aim should be to keep Snellen VA above 0.05 to have an impact on QoL. If it is certain that the best-corrected VA below 0.05 is permanent, these findings imply there may be less, if any, benefit to continue further treatment. This is to be evaluated on a case-by-case basis.

Psychological impact of anti-VEGF treatments for wet macular degeneration-a review.

PURPOSE: To review the current literature on the psychological impact of anti-VEGF treatments for wet age-related macular degeneration (wAMD), in terms of patients' experiences of receiving these treatments, and the impact of these treatments for patients' mental health and quality of life. METHODS: We critically analyzed current literature evaluating psychological impact of anti-VEGF treatments for wAMD. Primary searches of PubMed, Science Direct, and Web of Science were conducted in July and August of 2015. We reviewed all papers on the topic published until August 5, 2015. RESULTS: Our literature search found 14 papers addressing the psychological impact of anti-VEGF treatments for wAMD. Results highlighted potential anxieties and experiences of pain caused by receiving regular intravitreal injections. A positive visual outcome of anti-VEGF therapy is associated with positive vision-related QOL outcomes, although such association seems to be dependent on improvements on visual acuity. In the literature reviewed, patients receiving anti-VEGF treatments showed a prevalence rate of depression between 20 and 26 %. CONCLUSIONS: Although anti-VEGF treatments can cause some anxiety and being experienced as a stressful event, especially in the beginning of the treatment, preliminary findings suggest a potential benefit for long-term vision-related quality of life. Further longitudinal and qualitative research should bring more evidence on the positive and negative effects of these treatments on patients' long-term mental health.

Management of Neovascular Age-related Macular Degeneration: A Review on Landmark Randomized Controlled Trials.

In the last decade, a number of prospective clinical trials with carefully designed study protocols have been conducted for the treatment of neovascular age-related macular degeneration (AMD). These landmark clinical trials such as ANCHOR and MARINA and, more recently, the Comparison of AMD Treatment Trials and VIEW studies have revolutionized the management of neovascular AMD. While AMD continues to remain a leading cause of severe visual loss worldwide, advances in pharmacotherapeutics have led to substantial improvements in the outcome of these patients. The introduction of anti-vascular endothelial growth factor agents has resulted in improvement of visual outcomes and has had a positive impact on the quality of life among elderly population. While the contemporary management of neovascular AMD has been successful in tremendously reducing the visual morbidity, the financial burden of therapy has increased exponentially. To overcome these challenges, newer pharmacologic agents are evaluated for their efficacy and safety in AMD. Ground-breaking advances in bench to bedside research have led to discovery of new pathways that appear to be viable targets for preventing visual loss in AMD. In this review, study designs and results of landmark clinical trials in AMD from the past decade have been summarized.

The role of Aflibercept in the management of age-related macular degeneration.

INTRODUCTION: During the past decade, significant advances have occurred in the management of neovascular age-related macular degeneration (NV-AMD). The advent of anti-vascular endothelial growth factor (anti-VEGF) therapy has shifted the treatment goal of NV-AMD from merely salvaging vision to improving visual acuity and maintaining a good quality of life. Aflibercept (AFL) is a significant addition to the arsenal of anti-VEGF therapies against the NV-AMD. In the index review, pharmacology and efficacy of AFL has been reviewed. AREAS COVERED: An extensive literature search was performed to identify preclinical and clinical studies performed to illustrate the role of AFL in NV-AMD. Randomized clinical trials evaluating other anti-VEGF agents were also included for comparison. Additionally, studies where AFL was employed to treat anti-VEGF-resistant cases agents have been reviewed. EXPERT OPINION: AFL is an effective agent in the management of NV-AMD and its efficacy has been found to be comparable to ranibizumab (RBZ). Additionally, AFL is a good alternative agent in patients with NV-AMD resistant to RBZ and bevacizumab (BVZ), and can potentially lessen the treatment burden. As more research is conducted, the role of AFL in varying dosing regimens, as monotherapy and in combination with other agents, will become further defined.

Patient perceptions and experiences of stereotactic radiotherapy for wet age-related macular degeneration.

PURPOSE: Wet age-related macular degeneration (ARMD) is a leading cause of visual impairment. Anti-vascular endothelial growth factor (VEGF) injections are the mainstay of treatment but require monthly injections and frequent hospital visits. A novel approach to treatment with the use of stereotactic radiotherapy (Oraya IRay) as an adjunct to ranibizumab injections has shown promising results. We explored patients' experiences of receiving Oraya therapy for wet ARMD. METHODS: We present a consecutive case series with objective and detailed reporting of the personal experiences of 5 patients with active wet ARMD treated with Oraya radiotherapy in our unit. We provided all patients who had received one Oraya treatment with a standardized survey composed of 10 questions addressing the experience of receiving this treatment. RESULTS: Generally, patients reported positive experiences of receiving Oraya treatment and perceived this treatment as a better option in comparison with anti-VEGF injections. However, the patients' perceptions of Oraya treatment varied according to patients' previous experiences of anti-VEGF injections and expectations of treatment. CONCLUSIONS: Patients mainly justified their decision to receive Oraya treatment by expecting fewer intravitreal injections, but more research on this topic is needed to suggest new evidence-based treatment protocols for patients with wet ARMD.
