Introduction: Age-related macular degeneration (AMD) is the most common cause of central vision loss in elderly people over 50 years of age. It is characterized by the presence of drusen on the fundus and may be associated with choroidal neovascularization (CNV) or geographic atrophy. AMD is a condition caused by many factors including environmental, genetic, and vascular. Currently, it affects over 25 million people worldwide, but with the progressive aging of the population, the incidence of the disease is increasing. Disease is therefore an important issue in geriatrics.Case report: A 75-year-old patient was referred to the General and Pediatric Ophthalmology Clinic of the Medical University of Lublin due to the three-week deterioration of visual acuity in the left eye. The visual acuity of the left eye was: counting fingers at a distance of 1.5 m. Initial cataracts of this eye and wet AMD were diagnosed. In July 2018. an injection of ranibizumab was administered into the vitreous humor of the left eye. After achieving an improvement in visual acuity to 0.2 (on Snellen charts), in September the patient was qualified to the Drug Program for the treatment of the wet form of AMD. From September to October 2019. the patient received 9 doses of ranibizumab. In October 2019. visual acuity improved to 0.4. In November, due to the unsatisfactory results of the therapy, the drug was changed to aflibercept. The patient received a total of 3 injections of this drug and his visual acuity improved to a value of 0.7. The last injection was given in July 2020 and the clinical condition and visual acuity stabilized. After the end of the drug program, the patient regularly shows up for checkups, and the visual acuity of the left eye has normalized since July 2020. and is now 0.4 (due in part to atrophic changes and scarring).Conclusions: Treatment of the wet form of AMD is a difficult and lengthy process. Early diagnosis of the disease, starting treatment as soon as possible, regular checkups and cooperation with the patient are very important for the success of the therapy. During 3 years of treatment, the patient experienced a significant improvement in visual acuity for one year. The treatment allowed the disease progression to slow down. The morphological condition of the retina improved. The applied treatment and management of the elderly patient turned out to be effective, and the achieved effects of the therapy are satisfactory.

Age-related macular degeneration (AMD) is the major cause of blindness for the elderly population in the developed world. Although vision loss is mainly due to the neovascular form, dry AMD remains a challenge for ophthalmologists because of the lack of effective therapies. The Age-Related Eye Disease Study (AREDS) demonstrated the protective effect of dietary supplementation of antioxidants to slow down the progression of dry AMD. On the other hand, there has been no proven drug treatment for dry AMD to date. This review is aimed to discuss recent non-nutritional treatments for dry AMD and geographic atrophy.

The Swedish Lucentis Quality Registry is a 12-month, open-label, observational, prospective, and retrospective study of ranibizumab administration for wet AMD. Visual acuity (VA) was measured with Snellen or ETDRS chart in 370 patients (66.8% women; age range 46–93 years). In total, a mean of4.7±1.6injections per patient (range 1–10) was given to month 12. Mean VA score was58.3±12.2letters before treatment,63.3±12.5after 3 injections (Δ4.9±10.1letters from baseline), and59.3±16.2at 12 months (Δ1.0±13.6). VA score from baseline to month 12 was stable in 74.4% of patients, improved by 15 letters/3 lines or more in 14.7%, and decreased by≥15 letters/3 lines in 10.9% of patients. With a mean of 4.7 ranibizumab injections per patient per year, mean VA was stabilised but not increased. To maintain the initial gain seen after the first three injections, an average of1.8±1.5additional injections does not appear to be adequate.

The current treatment of neovascular age-related macular degeneration (nAMD) generates an excessive care pressure in the public health system. The search for a satisfactory treatment regimen, whose anatomical and functional stability may be achieved, is a challenge and a goal to be reached. We analyzed the outcomes in a patient cohort under fixed regimen treatment with intravitreal aflibercept (IVA). A retrospective study, with at least 1-year follow-up, in consecutive treated unselected naïve patients was carried out. Standard protocol was performed and evaluated at baseline, month 4 (after loading dose, LD), and month 12 (after fixed bimonthly regimen). One hundred six patients (123 eyes) aged 80.3 ± 7.7 years were included, receiving 6.8 ± 0.7 IVA. Visual acuity gain after LD was 5.5 ± 12.0 letters ( p < 0.0001 ). At month 12, 23 eyes (18.7%) gained ≥15 letters and 58 (47.1%) had best-corrected visual acuity ≥20/40 (70 letters). The improvement in visual acuity was lower in patients with polypoidal choroidal vasculopathy (+4.9 ± 18.1 letters; p = 0.2544) and somewhat higher in patients with retinal angiomatous proliferation (+5.4 ± 12.3 letters; p = 0.0373 ). Dry macula was present in only 9.8% of cohort at baseline vs. 69.7% at month 12 ( p < 0.0001 ). Atrophy was the most observed complication and related to the elderly patients. The average of follow-up visits was 3 ± 0.5. Functional and anatomical improvement were observed with IVA in a fixed bimonthly regimen treatment after LD, with results maintained up to one year with a good compliance. The fixed bimonthly regimen optimized patient management and logistic issues.

AbstractAge-related macular degeneration (AMD) is a devastating retinal disease that results in irreversible vision loss in the aged population. The complex genetic nature and degree of genetic penetrance require a redefinition of the current therapeutic strategy for AMD. We aimed to investigate the role of modifiers for current anti-VEGF therapy especially for non-responder AMD patients. We recruited 78 wet AMD cases (out of 278 AMD patients) with their socio-demographic and treatment regimen. Serum protein levels were estimated by ELISA in AMD patients. Data pertaining to the number of anti-VEGF injections given (in 1 year) along with clinical images (FFA and OCT) of AMD patients were also included. Visual acuity data (logMAR) for 46 wet AMD cases out of a total of 78 patients were also retrieved to examine the response of anti-VEGF injections in wet AMD cases. Lipid metabolizing genes (LIPC and APOE) have been identified as chief biomarkers for anti-VEGF response in AMD patients. Both genotypes ‘CC’ and ‘GC’ of LIPC have found to be associated with a number of anti-VEGF injections in AMD patients which could influence the expression of B3GALTL,HTRA1, IER3, LIPC and SLC16A8 proteins in patients bearing both genotypes as compared to reference genotype. Elevated levels of APOE were also observed in group 2 wet AMD patients as compared to group 1 suggesting the significance of APOE levels in anti-VEGF response. The genotype of B3GALTL has also been shown to have a significant association with the number of anti-VEGF injections. Moreover, visual acuity of group 1 (≤ 4 anti-VEGF injections/year) AMD patients was found significantly improved after 3 doses of anti-VEGF injections and maintained longitudinally as compared to groups 2 and 3. Lipid metabolising genes may impact the outcome of anti-VEGF AMD treatment.

Purpose. To study the effects of vitrectomy on the course of wet age-related macular degeneration (AMD). Materials and methods. 99 patients (99 eyes) with wet AMD associated with vitreo-macular adhesion or posterior hyaloid traction were included in the study. During the first 6 months, all patients received anti-VEGF treatment according to a PRN regimen. Then, they were divided into two groups: in 45 patients vitrectomy was performed and 54 patients did not receive surgical treatment. The follow-up period duration was one year. Results. At the beginning of the study, visual acuity was 0.27 ± 0.17 in the control group, and 0.17 ± 0.15 in the treatment group. Most prominent differences in visual acuity between the two groups were observed during the first 6 months (visual acuity in the treatment group before surgery was 0.12 ± 0.1) (p < 0.01 and p < 0.001), at the same time during the following 6 follow-up months, this difference decreased (p < 0.05 and p < 0.01). 1 year from the study start, visual acuity in the control group was 0.24 ± 0.17, and 0.17 ± 0.13 in the treatment one. Conclusions. Vitrectomy surgery in patients with wet AMD in association with vitreo-macular adhesion or posterior hyaloid traction does not exacerbate the disease course, stabilizes visual functions and improves the quality of life.

Abstract Background Polypoidal choroidal vasculopathy (PCV) is a type of age-related macular degeneration that can cause permanent vision loss. The purpose of this paper was to report the one-year outcomes of fixed-dosing aflibercept therapy for the treatment of PCV. Methods This was a prospective, single-arm, interventional case series study of 25 PCV patients; 12 pre-treated and 13 treatment-naïve patients. The patients were treated and monitored for 12 months. Each patient was administered with an aflibercept (2.0 mg) injection every month for the first 3 months (the loading phase), and thereafter, once every 2 months. At every follow-up visit, best-corrected visual acuity (BCVA) test, fundus examination, and optical coherence tomography for measuring the central subfield macular thickness (CSMT) were performed. Fluorescein and indocyanine green angiography were conducted at baseline and at 4 and 12 months. Results After 12 months of aflibercept therapy, the mean BCVA of the patients significantly improved from 65.48 letters at baseline to 69.91 letters (p=0.001), and the CSMT significantly decreased from 406.92 um at baseline to 276.12 um (p< 0.001). Additionally, ten patients (40%) showed complete polyp regression. The treatment-naïve patients showed a statistically significant improvement in BCVA from 66.58 letters at baseline to 76.36 letters at 12 months, and a significant decrease in CSMT, from 462 to 243 um. In the pre-treated group, there was no change in BCVA (64.46 letters), and the decrease in CSMT from 356.08 to 303.69 um was not statistically significant. Conclusions The fixed-dosing aflibercept regimen is effective for treating patients with PCV and is more effective in treatment-naïve patients than in pre-treated patients.

AbstractOuter retinal tubulations (ORT) are a relatively new finding characterizing outer retinal atrophy. The main aim of the present study was to describe ORT development in advanced age-related macular degeneration (AMD) and to assess its relationship with disease’s severity. Patients with advanced AMD characterized either by macular neovascularization or geographic atrophy, showing signs of outer retinal disruption or retinal pigment epithelium atrophy on structural optical coherence tomography (OCT) at the inclusion examination were prospectively recruited. All the patients underwent complete ophthalmologic evaluation, structural OCT scans and fundus autofluorescence imaging. The planned follow-up was of 3-years. Main outcome measures were ORT prevalence, mechanism of ORT formation, mean time needed for complete ORT formation, best-corrected visual acuity (BCVA), definitely decreased autofluorescence (DDAF) area, questionably decreased autofluorescence (QDAF) area, retinal layer thickness, foveal sparing, number of intravitreal injections. We also assessed the possible role of external limiting membrane (ELM) and Müller cells in ORT pathogenesis. Seventy eyes (70 patients) were included; 43 showed dry AMD evolving to geographic atrophy, while 27 displayed the features of wet AMD. Baseline BCVA was 0.5 ± 0.5 LogMAR, decreasing to 0.9 ± 0.5 LogMAR at the 3-year follow-up (p < 0.01). We detected completely formed ORT in 26/70 eyes (37%), subdivided as follows: 20 eyes (77%) wet AMD and 6 eyes (23%) dry AMD (p < 0.01). ORT took 18 ± 8 months (range 3–35 months) to develop fully. We described the steps leading to ORT development, characterized by progressive involvement of, and damage to the photoreceptors, the ELM and the RPE. Eyes displaying ORT were associated with a smaller QDAF area, less retinal layers damage and lower rate of foveal sparing than eyes free of ORT (p < 0.01). We also described pigment accumulations simulating ORT, which were detected in 16/70 eyes (23%), associated with a greater loss of foveal sparing, increased DDAF area and smaller QDAF area at the 3-year follow-up (p < 0.01). In conclusion, this study provided a description of the steps leading to ORT development in AMD. ELM and Müller cells showed a role in ORT pathogenesis. Furthermore, we described a subtype of pigment hypertrophy mimicking ORT, evaluating its clinical utility.

AbstractProlonged life expectancies contribute to the increasing prevalence of age-related macular degeneration (AMD) that is already the leading cause of severe vision loss among the elderly in developed countries. In dry AMD, the disease culminates into vast retinal atrophy, whereas the wet form is characterized by retinal edema and sudden vision loss due to neovascularization originating from the choroid beneath the Bruch’s membrane. There is no treatment for dry AMD and despite intravitreal injections of anti-vascular endothelial growth factor (VEGF) that suppress the neovessel formation, also wet AMD needs new therapies to prevent the disease progression and to serve patients lacking of positive response to current medicines. Knowledge on disease mechanisms is a prerequisite for the drug development, which is hindered by the multifactorial nature of AMD. Numerous distinguished publications have revealed AMD mechanisms at the cellular and molecular level and in this multi-author review, we take a bit broader look at the topic with some novel aspects.

Purpose Differential diagnosis of maculopathies can be difficult but is important if patients also suffer from other diseases such as breast cancer treated with antiestrogens. The main possible diagnoses, especially in the elderly, are age-related macular degeneration, tamoxifen and cancer-associated retinopathy (CAR). Methods We describe an 84-year-old patient with breast and colon cancer, who complained of a decrease in visual acuity after treatment with low-dose antiestrogens. She underwent a general ophthalmological investigation, perimetry and electroretinographic examination with multifocal (m-ERG) and flash-electroretinogram (flash-ERG). Results Visual acuity was reduced to 1/50 and 0.3. The ophthalmological examination was normal, except for extensive bilateral maculopathy with shining crystalline deposits, central and peripheral visual field defects, slightly affected scotopic and photopic potentials in the flash-ERG, and an abnormal m-ERG. Conclusions The findings are expected with age-related macular degeneration with crystalline drusen, but also with CAR. Even if the single and total dosage of antiestrogens given to the patient is sufficient to cause tamoxifen retinopathy, this diagnosis can be excluded because, in tamoxifen retinopathy unlike in the case presented here, the deposits are not distributed in all retinal layers.

And Function

Age-related macular degeneration (AMD) is a major cause of irreversible vision loss. The neovascular or “wet” form of AMD can be treated to varying degrees with anti-angiogenic drugs, but geographic atrophy (GA) is an advanced stage of the more prevalent “dry” form of AMD for which there is no effective treatment. Development of GA has been linked to loss of the microRNA (miRNA)-processing enzyme DICER1 in the mature retinal pigmented epithelium (RPE). This loss results in the accumulation of toxic transcripts of Alu transposable elements, which activate the NLRP3 inflammasome and additional downstream pathways that compromise the integrity and function of the RPE. However, it remains unclear whether the loss of miRNA processing and subsequent gene regulation in the RPE due to DICER1 deficiency also contributes to RPE cell death. To clarify the role of miRNAs in RPE cells, we used two different mature RPE cell-specific Cre recombinase drivers to inactivate either Dicer1 or DiGeorge syndrome critical region 8 (Dgcr8), thus removing RPE miRNA regulatory activity in mice by disrupting two independent and essential steps of miRNA biogenesis. In contrast with prior studies, we found that the loss of each factor independently led to strikingly similar defects in the survival and function of the RPE and retina. These results suggest that the loss of miRNAs also contributes to RPE cell death and loss of visual function and could affect the pathology of dry AMD.
