Variable response of sub-retinal hyper-reflective membranes to anti-vascular endothelial growth factor treatment in bilateral neo-vascular age-related macular degeneration

Sub-retinal hyper-reflective material (SHRM) is an important spectral-domain optical coherence tomography biomarker in neo-vascular age-related macular degeneration (nAMD). The exact nature of SHRM is not known, but it may contain fluid, fibrin, blood, neo-vascular tissue, and so on. Although nAMD with avascular SHRM usually resolves with anti-vascular endothelial growth factor and is known to have better visual prognosis, those with vascular SHRM have significantly poor final vision. We present a unique case of nAMD with an avascular SHRM in the right eye and a vascular SHRM in the left eye and how the two eyes behaved with treatment over a period of 12 months.

Characterizing Progression to Neovascular AMD in Fellow Eyes of Patients Treated With Intravitreal Anti-VEGF Injections.

The purpose of this study was to assess the real-world incidence of conversion to bilateral neovascular age-related macular degeneration (nAMD) following treatment initiation of nAMD in the initial eye. This was a retrospective cohort of electronic health records from retinal centers across the United States (Vestrum Database) of all patients with unilateral nAMD treated with anti-vascular endothelial growth factor therapy. A total of 22,553 patients with unilateral nAMD were included. Fellow eyes of 8,522 patients (38%) converted to nAMD. Among these, 2,639 (12%), 2,030 (9%), and 1,802 (8%) patients converted in Years 1, 2, and 3, respectively, after diagnosis in the first eye. Fellow eyes had better vision at conversion and 1 year following conversion. The fellow eye should be monitored at regular intervals to detect signs of neovascularization. Fellow eyes presented with significantly better vision at diagnosis than the initial eye and maintained better visual acuity with less injections.

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

PurposeBilateral 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).MethodsA 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).ConclusionsFor 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.

Cost-minimization Analysis of Ranibizumab versus Aflibercept in the Treatment of Neovascular Age-related Macular Degeneration in Colombia

ABSTRACT Background In 2020 Colombia may expect to have close to 231,700 patients with neovascular age-related macular degeneration (ARMD). Treatment of neovascular ARMD involves the sequential Intra-vitreal injections of anti-vascular endothelial growth factor (anti-VEGF therapy) medications. The efficacy and safety of anti-VEGF therapy on a treat-and-extend (T&E) dosing scheme are similar when ranibizumab or aflibercept are administered. Objective : A cost-minimization analysis from the payer`s perspective in Colombia projects treatment expenses of anti-VEGF therapy using aflibercept or ranibizumab on T&E regimens for the treatment of neovascular ARMD. Methods : A model projects the expenses of the compared treatment regimens for two and five-year periods beginning on February 2020. The model used information from clinical trials, case series and meta-analyses on the compared treatment regimens, demographic, epidemiologic and economic data originated from the Colombian government sources. A 3% discount rate was applied. Results : Projected cost differences in favor of ranibizumab after two and five-year treatment periods beginning February 2020 could be close to U.S. $ 4,861 and U.S $ 7,241 per treated eye, respectively. If all patients with unilateral and bilateral neovascular ARMD in Colombia were to receive appropriate anti-VEGF therapy for two years, the projected expected cost difference in favor of ranibizumab could be close to U.S. $ 462,717,092 dollars. Conclusion : Within the Colombian healthcare setting anti-VEGF therapy on a T&E regimen utilizing ranibizumab for neovascular ARMD may be cost-saving compared with employing aflibercept. Despite cost favorability, ranibizumab should not be the only therapeutic option since in clinical practice alternatives are required.

A genome-wide association study identified a novel genetic loci STON1-GTF2A1L/LHCGR/FSHR for bilaterality of neovascular age-related macular degeneration

Bilateral neovascular age-related macular degeneration (AMD) causes much more handicaps for patients than unilateral neovascular AMD. Although several AMD-susceptibility genes have been evaluated for their associations to bilaterality, genome-wide association study (GWAS) on bilaterality has been rarely reported. In the present study, we performed GWAS using neovascular AMD cases in East Asian. The discovery stage compared 581,252 single nucleotide polymorphisms (SNPs) between 803 unilateral and 321 bilateral Japanese cases but no SNP showed genome-wide significance, while SNPs at six regions showed P-value < 1.0 × 10−5, STON1-GTF2A1L/LHCGR/FSHR, PLXNA1, CTNNA3, ARMS2/HTRA1, LHFP, and FLJ38725. The first replication study for these six regions comparing 36 bilateral and 132 unilateral Japanese cases confirmed significant associations of rs4482537 (STON1-GTF2A1L/LHCGR/FSHR), rs2284665 (ARMS2/HTRA1), and rs8002574 (LHFP) to bilaterality. In the second replication study comparing 24 bilateral and 78 unilateral cases from Singapore, rs4482537 (STON1-GTF2A1L/LHCGR/FSHR) only showed significant association. Meta-analysis of discovery and replication studies confirmed genome-wide level significant association (P = 2.61 × 10−9) of rs4482537 (STON1-GTF2A1L/LHCGR/FSHR) and strong associations (P = 5.76 × 10−7 and 9.73 × 10−7, respectively) of rs2284665 (ARMS2/HTRA1) and rs8002574 (LHFP). Our GWAS for neovascular AMD bilaterality found new genetic loci STON1-GTF2A1L/LHCGR/FSHR and confirmed the previously reported association of ARMS2/HTRA1.

Complement factor H and LOC387715/ARMS2/HTRA1 variant's frequencies and phenotypic associations in neovascular age-related macular degeneration, a pilot study

PurposeTo evaluate the frequency of 12 single nucleotide polymorphisms (SNPs) of complement factor H (CFH) and LOC387715/ARMS2/HRTA1 and their association with some of the presenting clinical features of neovascular age-related macular degeneration (AMD). MethodsIn this prospective non-comparative case series forty four naïve patients with neovascular AMD were genotyped using sequencing or Sequenom iPLEX technology. Descriptive tests were used for displaying the magnitude of each allele, gender distribution, and age at diagnosis. Fisher exact test was used to evaluate the correlation between visual acuity (VA) and different alleles. Also Kruskal-Wallis test was used for comparison between age at the time of diagnosis and different alleles. ResultsThe most frequent SNP among studied patients was rs1061147 with 100% frequency rate. The least common was rs2672598 with a frequency of 52.27%. Only the allele rs800292 of CFH locus on 1q32 was associated with VA better than 20/200 (p value = 0.034). The frequency of this allele was 77.27% (34 patients) in this study. There was no significant association between any of alleles, and VA worse than 20/200(p > 0.05). Fifteen patients had bilateral exudative AMD (34.09%). There was no significant difference between alleles in bilateral neovascular AMD and unilateral disease. Also bilateral and unilateral patients were not different in terms of age, gender or VA (p value: 0.330, 0.764 and 0.456 respectively). There was also no significant association between any of SNPs and bilaterality of disease. ConclusionWe designated the frequencies of SNPs of CFH and LOC387715/ARMS2/HRTA1 in neovascular AMD in a sample of Iranian patients. Only the allele rs800292 of CFH locus on chromosome 1q32 was associated with better VA.

Visual acuity at presentation in the second eye versus first eye in patients with exudative age-related macular degeneration.

To assess the difference in best-corrected visual acuity (BCVA) at presentation between the first and second eye in patients with bilateral neovascular age-related macular degeneration (AMD). We reviewed the charts of all patients who had a clinical examination for neovascular AMD at the University Eye Clinic of Creteil in January 2013. We retrospectively analyzed demographic and clinical data for 264 patients. In the fellow eye, choroidal neovascularization (CNV) developed in 75/264 patients (28.4%) with a time interval between the 2 events of 30.3 months (range 6-145). Data were available on 65 patients: 14/65 (21.5%) were asymptomatic, 24/65 (36.9%) had BCVA >20/40, whereas at the time of CNV diagnosis in the first eye, no patient was asymptomatic (p<0.0001), and 11/65 (16.9%) eyes had BCVA >20/40 (p<0.0001). The mean BCVA of the first affected eye was 0.68 (± 0.41) logarithm of minimum angle of resolution (logMAR) and the mean BCVA for the second eye was 0.36 (± 0.29) logMAR (p<0.0001). The BCVA at the time of diagnosis of CNV was higher in the second eye than in the first affected eye. This was possibly due to several factors including systematic bilateral examination in follow-up of unilateral exudative AMD that allowed detection of 20% of cases.

Neovascular age-related macular degeneration associated with no light perception.

To study eyes with no light perception (NLP) occurring secondary to neovascular age-related macular degeneration (AMD). Records of consecutive patients with neovascular AMD seen during a 10-year period were reviewed to ascertain which patients had NLP due to neovascular AMD. Ten of 1,150 patients (0.9%) with neovascular AMD had NLP in one eye (study eye) from neovascular AMD. All 10 patients had bilateral neovascular AMD. Each study eye had a large macular disciform scar and 360° peripapillary subretinal fibrovascular tissue. Seven of nine (78%) study eyes had optic disc pallor, versus none of eight fellow eyes (P = .04). Mean fellow eye vision was 20/231, ranging from 20/50 to NLP (P = .006 vs study eyes). No seeing fellow eye had choroidal neovascularization encircling the optic disc (P = .0004). NLP from neovascular AMD is associated with 360° peripapillary subretinal fibrosis. This fibrosis may cause chronic ischemic optic neuropathy contributing to extinguished vision.

Objective Visual Assessment of Antiangiogenic Treatment for Wet Age-Related Macular Degeneration

To assess cortical responses in patients undergoing antiangiogenic treatment for wet age-related macular degeneration (AMD) using functional magnetic resonance imaging (fMRI) as an objective, fixation-independent measure of topographic visual function. A patient with bilateral neovascular AMD was scanned using fMRI before and at regular intervals while undergoing treatment with intravitreal antiangiogenic injections (ranibizumab). Blood oxygenation level-dependent signals were measured in the brain while the patient viewed a stimulus consisting of a full-field flickering (6 Hz) white light alternating with a uniform gray background (18 s on and 18 s off). Topographic distribution and magnitude of activation in visual cortex were compared longitudinally throughout the treatment period (<1 year) and with control patients not currently undergoing treatment. Clinical behavioral tests were also administered, including visual acuity, microperimetry, and reading skills. The area of visual cortex activated increased significantly after the first treatment to include more posterior cortex that normally receives inputs from lesioned parts of the retina. Subsequent treatments yielded no significant further increase in activation area. Behavioral measures all generally showed an improvement with treatment but did not always parallel one another. The untreated control patient showed a consistent lack of significant response in the cortex representing retinal lesions. Retinal treatments may not only improve vision but also result in a concomitant improvement in fixation stability. Current clinical behavioral measures (e.g., acuity and perimetry) are largely dependent on fixation stability and therefore cannot separate improvements of visual function from fixation improvements. fMRI, which provides an objective and sensitive measure of visual function independent of fixation, reveals a significant increase in visual cortical responses in patients with wet AMD after treatment with antiangiogenic injections. Despite recent evidence that visual cortex degenerates subsequent to retinal lesions, our results indicate that it can remain responsive as its inputs are restored.

EPIDEMIOLOGY OF THE ASSOCIATION BETWEEN ANTICOAGULANTS AND INTRAOCULAR HEMORRHAGE IN PATIENTS WITH NEOVASCULAR AGE-RELATED MACULAR DEGENERATION

To determine the cumulative incidence and annual incidence of intraocular hemorrhage (subretinal hemorrhage or vitreous hemorrhage) in patients with neovascular age-related macular degeneration (AMD) and association with daily antiplatelet or anticoagulant (AP/AC) medication usage (aspirin, clopidogrel, and warfarin), age, gender, hypertension, diabetes mellitus, or bilateral neovascular AMD. Retrospective cross-sectional study in a tertiary university setting. Data on 195 eyes of 195 patients without previous intraocular hemorrhage examined over 73 months were reviewed. Ninety-six of 195 patients (49.2%) were taking daily AP/ACs. Of patients taking daily AP/AC agents, 63.5% had hemorrhage compared with 29.2% of patients not taking (odds ratio = 4.21; 95% confidence interval = 1.42-8.46; P < 0.001). The overall annual incidence of intraocular hemorrhage was 0.14% per year. Among patients taking daily AP/AC, the cumulative incidence (61 of 96, 63.5%) and annual incidence (0.10%) of concurrent intraocular hemorrhage were significantly greater compared with patients not taking them (29 of 99, 29.2% and 0.04%, respectively; P < 0.0001). Fourteen of 18 patients (77%) taking more than 1 daily AP/AC had occurrence of intraocular hemorrhage. Antiplatelet or anticoagulant usage was an independent risk factor for the development of intraocular hemorrhage. The use of any agent resulted in a significantly increased risk of developing intraocular hemorrhage. Additionally, presence of bilateral neovascular AMD was a significant association in those taking daily AP/ACs, whereas age was a significant association in those not taking daily AP/AC agents. All three daily AP/AC types were significantly associated with an increased risk of the development intraocular hemorrhage in patients with neovascular AMD, whereas gender, hypertension, and diabetes were not. Age was not significantly associated with hemorrhage in patients taking daily AP/AC agents, whereas the presence of bilateral neovascular AMD was significantly associated with hemorrhage. These findings indicate that the AP/AC use may predispose patients with neovascular AMD to intraocular hemorrhage more so than age and duration of disease alone. While the risk that discontinuing these medicines would pose to the patients' health may be too great to justify, ensuring that an appropriate medication dosage is maintained should be a priority within this patient population.

Blindness from suprachoroidal haemorrhage in two patients with age‐related macular degeneration on systemic anticoagulation therapy or an antiplatelet agent

Clinical record Patient 1 A 90-year-old man with bilateral neovascular age-related macular degeneration (AMD) presented with sudden onset of painful visual loss in his left eye. Visual acuity in his right eye was 1/60 due to scarring associated with AMD, and visual acuity in his left eye had deteriorated to hand movements; it had previously been 6/120. He had been taking warfarin for about 2 years for atrial fibrillation and a transient ischaemic attack. The international normalised ratio (INR) had previously been measured almost weekly, but as it had been stable at 2.5–2.9 (target INR, 2.0–3.0), it had not been measured for 6 weeks. B-mode ultrasonography and dilated fundus examination revealed massive suprachoroidal haemorrhage (Figures A and B). The INR was 6.0, which was reversed with intravenous administration of two units of fresh frozen plasma and 1 mg of vitamin K. Visual acuity in the patient’s left eye deteriorated to light perception. As there were no signs of spontaneous improvement and this had been his better eye, surgery was performed to drain the haemorrhage. After surgery, the haemorrhage decreased in size but his vision did not improve.

Endophtalmie aiguë unilatérale à Staphylococcus epidermidis après injection intra-vitréenne bilatérale et concomitante de ranibizumab à partir d’un même flacon : à propos d’un cas

To report a case of unilateral acute endophthalmitis due to Staphylococcus epidermidis after simultaneous bilateral intravitreal injection using the same ranibizumab vial. A 68-year-old phakic man had uneventful bilateral sequential ranibizumab intravitreal injection for bilateral neovascular age-related macular degeneration using the same vial. All of the vial contents (0.3 mL) were withdrawn through the filter needle attached to a 1-cc tuberculin syringe. Using the same syringe but separate injection needles, 0.05 mL was administrated to the right eye before 0.05 mL was injected into the left eye. Sterile gloves, drape, and eyelid speculum were used for each eye. Early Staphylococcus epidermidis postoperative endophthalmitis developed 3 days later in the right eye (injected first) with intense vitreous inflammation, limiting visual acuity to light perception. Management included intravitreal antibiotic agents and pars plana vitrectomy. The patient achieved an excellent visual outcome. This case report demonstrates that bacterial endophthalmitis is a rare but potential complication of intravitreal anti-VEGF injection, that infection generally results from self-contamination of the patient from his or her own bacterial flora, and that simultaneous bilateral intravitreal injection should be avoided.

Economic Burden of Bilateral Neovascular Age-Related Macular Degeneration

There is limited previous research examining the healthcare costs of neovascular age-related macular degeneration (NV-AMD), which constrains our understanding of the economic impact of this condition. With aging populations, this leading cause of rapid vision loss in Western countries is expected to become a pressing health predicament, requiring decision makers to evaluate alternative treatment strategies for AMD. To document the economic burden of bilateral NV-AMD, the late stage of AMD, in elderly patients, from a societal perspective. STUDY DESIGN, SETTING AND PARTICIPANTS: A cross-sectional, observational study surveyed 401 patients with bilateral NV-AMD and 471 non-AMD subjects in Canada, France, Germany, Spain and the UK. Physicians' records and subjects' standardized telephone interviews were used to record medical resource utilization, assistance with daily living and social benefits. Annual bilateral NV-AMD-related socioeconomic costs were calculated in euro, year 2005 values. Societal costs including direct vision-related medical costs (e.g. treatment of AMD and vision-related equipment), direct non-vision-related medical costs (e.g. medications) and direct non-medical-related costs (e.g. home healthcare and social services) were the main outcome measures. The demographic profile of NV-AMD patients was similar across countries; however, co-morbid condition profiles varied. NV-AMD patients reported substantial health-related problems and associated health resource utilization (HRU). In the previous 12 months, 12-22% of patients fell, and half of these patients required medical treatments. More than 20% (range 21-59%) of patients were prescribed vision-enhancing equipment. More than half of the patients (54-81%) were living with a spouse or family member and 19-41% reported receiving assistance for activities of daily living. The average annual societal cost per bilateral NV-AMD patient treated was estimated to be euro 7879 in Canada, euro 7349 in France, euro 12 445 in Germany, euro 5732 in Spain and euro 5300 in the UK, and direct vision-related medical costs accounted for 23-63% of the total cost. Half of the patients were diagnosed with bilateral NV-AMD for <1 year, with an average length of 5 months; there were no statistically significant differences in total annual costs per patient between these patients and those who were diagnosed with bilateral disease for > or =1 year. Estimated annual societal costs of bilateral NV-AMD patients in these countries ranged from euro 268 to euro 1311 million. Estimated annual societal costs of all NV-AMD patients in these countries ranged from euro 671 to euro 3278 million. Bilateral NV-AMD imposes significant functional impairment on patients, leading to increased HRU and a high societal cost burden. Differences in national healthcare systems and NV-AMD treatment patterns were reflected in the wide variation of NV-AMD costs across the five surveyed countries. Even though the prevalence rates and per-patient costs varied by country, the societal costs of NV-AMD patients were substantial in each country. Earlier intervention with effective therapies is expected to reduce disease burden and disability associated with NV-AMD and, thus, decrease the overall societal cost.

Burden and Health Care Resource Utilization in Neovascular Age-Related Macular Degeneration

To describe the burden of bilateral neovascular age-related macular degeneration (NV-AMD) on patient-reported functioning and health resource utilization. A cross-sectional study of 401 patients with bilateral NV-AMD and 471 elderly control subjects without AMD was conducted in 5 countries. Subjects completed a telephone survey, including the National Eye Institute 25-Item Visual Function Questionnaire, the EuroQol instrument, the Hospital Anxiety and Depression Scale, and history of falls, fractures, and health care resource utilization. The mean age for patients with NV-AMD was 78.1 years, and 65% were women. The patients reported 45% worse vision-related functioning, 13% worse overall well-being, and 30% more anxiety and 42% more depression symptoms than controls after adjusting for covariates (all, P < .001). The effect of NV-AMD was also observed as a doubled fall rate (16% vs 8% [P < .001]) and a quadrupled need for assistance with daily activities (29% vs 7% [P < .001]) in the patients compared with controls. The evidence of extensive decline in quality of life and increased need of daily living assistance for patients with NV-AMD compared with a control population substantiates the need for new treatments that prevent vision loss and progression to blindness.

Burden of illness of bilateral neovascular age-related macular degeneration in Spain

ABSTRACTBackground: The burden of illness, including health resource utilization and costs associated with bilateral neovascular age-related macular degeneration (Nv-AMD), was assessed in Spain.Patients and methods: As part of an international prospective, case-controlled study, 89 Spanish patients with bilateral Nv-AMD were recruited by retina specialists and 96 Spanish control subjects were recruited by general practitioners and ophthalmologists. Physicians recorded clinical data and visual acuity (VA). In a subsequent telephone interview, Nv-AMD patients and controls completed the National Eye Institute Visual Function Questionnaire (NEI VFQ)-25, the EuroQol (EQ-5D), and the Hospital Anxiety and Depression Scale (HADS) questionnaire. Annual vision-related and non-vision-related medical costs and non-medical-related costs were calculated from study-specific questions.Results: The mean age was 76.2 years for Nv-AMD patients and 61.9 years for control subjects. The adjusted mean (95% CI) NEI VFQ-25 summary score was 51.9 (48.5; 55.4) for Nv-AMD patients and 87.7 (85.5; 89.9) for control subjects (p < 0.05). The summary score of Nv-AMD patients decreased significantly with VA declination. Mean direct vision-related medical and non-medical-related costs were significantly greater for Nv-AMD patients than the control subjects, whereas non-vision-related medical costs were similar between groups. The total mean annual resource utilization cost was €5733 for Nv-AMD patients compared to €1070 for control subjects (p < 0.0001).Conclusions: Although the study design is subject to a number of limitations, patients with Nv-AMD in Spain have worse quality of life outcomes, greater depression, and higher healthcare costs as compared with similarly-aged individuals who are not affected by this disease.

IMPACT OF FLUORESCEIN ANGIOGRAPHIC CHARACTERISTICS OF MACULAR LESIONS ON OUTCOMES AFTER MACULAR TRANSLOCATION 360° SURGERY IN EYES WITH AGE-RELATED MACULAR DEGENERATION

To evaluate the relationship between preoperative lesion size and composition and visual outcomes at 1 year after macular translocation surgery with 360 degree peripheral retinectomy (MT360) for neovascular age-related macular degeneration (AMD). A prospective, interventional, consecutive, noncomparative case series of 64 patients with bilateral neovascular AMD treated with MT360 in the eye with more recent vision loss. Masked reviewers graded preoperative fluorescein angiograms for lesion size in Macular Photocoagulation Study disk areas (MPS DAs) and predominant lesion composition (classic or occult choroidal neovascularization or subretinal hemorrhage). Median changes in distance and near visual acuities and reading speed at 12 months after surgery were analyzed with respect to lesion size and composition. There was no significant difference between the outcomes for small-, medium- or large-sized preoperative lesions. Patients in each predominant lesion composition group had median improvement in visual outcomes with significant improvement in near visual acuity and reading speed for predominantly classic and occult lesions. MT360 stabilizes or improves visual function in patients with neovascular AMD irrespective of lesion size categories and with a variety of lesion compositions. Removal of the subretinal lesion and repositioning of the fovea over a healthier retinal pigment epithelial bed may account for these improvements.
