AIM: To investigate 3-year results in our neovascular age related macular degeneration (NV-AMD) patients treated with ranibizumab. METHODS: Retrospective study. Visual acuity (VA), a full biomicroscopic examination (anterior segment and fundus), and optical coherence tomography (OCT) findings were noted at every visit. All patients were followed monthly. The VA values for the visits closest to 12, 24, and 36mo were analysed. 101 eyes of 73 patients were enrolled. According to the initial VA, the patients were divided three groups: initial VA ≤35 (Group 1), 36-54 (Group 2), and ≥55 letters (Group 3). After three loading doses of 0.5 mg ranibizumab if retreatment was needed, again, 0.5 mg ranibizumab was administered RESULTS: Totally 57 of the 101 eyes were from males and 44 were from females. The average age was 75.1 years. The difference on the changes of VA among three groups at 24 and 36mo were statistically significant (P=0.02 and 0.001 respectively). At the end of the 36-month follow-up the VA increase in Group 2 was significant (P=0.001). At the 12, 24, and 36mo visits most of the eyes showed no VA loss and most of these eyes were in Group 1. The average number of injections administered was 7.3 and the average number of visits was 23.9 during the follow-up. CONCLUSION: VA improvement was significant in those with mild initial VA (36-54 letters). Most eyes showed no VA loss regardless of the initial VA. No correlation between the final VA and the average number of injections.

Purpose: To evaluate the levels of salusin-beta (β-SAL) in the serum in patients with age-related macular degeneration (ARMD). Methods: Our study was designed as a controlled comparative clinical study. The β-SAL levels in serums of age and sex-matched 20 healthy volunteers as controls (Group 1), 20 patients with dry-age related macular degeneration (d-ARMD) (Group 2) and 20 patients with wet-age related macular degeneration (w-ARMD) (Group 3) were measured with the enzyme-linked immunosorbent assay (ELISA) method. Results: In our study, it was found that age and gender didn’t show a statistically significant difference among the study groups (p > 0. 05). The mean serum β-SAL levels in Group 1, Group 2 and Group 3 were 1372,17 ± 1126.69 pg/mL; 1423,71 ± 1196.84 pg/mL and 940,57 ± 1092.05 pg/mL, respectively. Although the meanβ-SAL levels in w-ARMD seem numerically lower than both the control and d-ARMD groups, this difference among the study groups was not statistically significant (p > 0.05). Conclusion: Our study suggests that β-SAL levels in the patients with ARMD and healthy controls were not different than each other. Further studies with large numbers may reveal possible relationships between β-SAL and ARMD.

Abstract To investigate changes in the size of the population of patients who are receiving long-term, active treatment for neovascular age-related macular degeneration (AMD). This retrospective, observational study included 3,380 patients who received anti-vascular endothelial growth factor injections (3,974 eyes). The injections performed were divided into the following three groups: group 1, injections performed right after the initial diagnosis; group 2, injections performed <24 months; and group 3, injection performed ≥24 months. Time-dependent changes in the proportion of injections in each group were analyzed. The total number of injections markedly increased from 431 in the 1st quarter of 2014 to 1,323 in the 4th quarter of 2018. There were significant changes in the proportion of injections in each group over time (P < 0.001). The proportions of group 1, group 2, and group 3 in the 1st quarter of 2014 were 17.4%, 65.4%, and 17.2%, respectively. The proportions changed to 10.6%, 50.2%, and 39.5% in the 4th quarter of 2018, respectively. The marked increase in the proportions of group 3 may suggest an increase in the patient population that underwent long-term active treatment. The socioeconomic influence of this trend should be considered when establishing future strategies for neovascular AMD.

Abstract Background To assess the morphological and functional outcome of intravitreal aflibercept following the treat and extend protocol compared to the fixed protocol for treatment of eyes with neovascular age-related macular degeneration. Methods This retrospective study included 126 eyes of 113 patients with primary onset neovascular age-related macular degeneration who were followed for 12 months. All eyes were treated with 2 mg/0.05 mL aflibercept. All eyes received an upload with three monthly aflibercept injections. We subsequently studied two groups of eyes. For group 1, 54 eyes were treated following the treat and extend protocol. For group 2, 72 eyes were treated following the fixed protocol (fixed 2-monthly interval). Main outcome measures included: best corrected visual acuity (BCVA), central macular thickness (CMT) and number of injections. Results BCVA (logMAR) in group 1 vs group 2 was (0.61 ± 0.3 vs 0.72 ± 0.3, p = 0.09) before treatment and (0.48 ± 0.3 vs 0.51 ± 0.3, p = 0.6) after one year of treatment. CMT in group 1 vs group 2 was (371 ± 101 μm vs 393 ± 116 μm, p = 0.5) before treatment and (284 ± 60 μm vs 290 ± 67 μm, p = 0.1) after one year of treatment. Number of injections/eye in group 1 vs group 2 was (8.5 ± 2.2 vs 7.0 ± 0, p < 0.001). Conclusions Significant differences regarding BCVA and central macular thickness were not found between both treatment protocols during the first year of treatment using aflibercept. However, a significantly higher number of injections was needed for eyes in the treat and extend group during the first year of treatment. This might suggest that aflibercept should better not be extended past an 8 weeks interval during the first year of treatment. Study registration This study was approved by the Ethics Committee of the Medical Association of Saarland, Germany (Nr. 123/20, Date: 16.06.2020). All procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards.

Macular pigment (MP) is composed of lutein (L), zeaxanthin (Z) and meso-zeaxanthin (MZ). The present study reports on serum response to three different MP supplements in normal subjects (n 27) and in subjects with age-related macular degeneration (AMD) (n 27). Subjects were randomly assigned to: Group 1 (20 mg L and 2 mg Z), Group 2 (10 mg L, 2 mg Z and 10 mg MZ) or Group 3 (3 mg L, 2 mg Z and 17 mg MZ). Serum carotenoids were quantified at baseline, and at 4 and 8 weeks using HPLC. Response data for normal and AMD subjects were comparable and therefore combined for analysis. We report response as the average of the 4- and 8-week concentrations (saturation plateau). Serum L increased significantly in Group 1 (0·036 μmol/l per mg (269 %); P< 0·001) and Group 2 (0·079 μmol/l per mg (340 %); P< 0·001), with no significant change in Group 3 (0·006 μmol/l per mg (7 %); P= 0·466). Serum Z increased significantly in Group 1 (0·037 μmol/l per mg (69 %); P= 0·001) and Group 2 (0·015 μmol/l per mg (75 %); P< 0·001), with no significant change in Group 3 ( − 0·0002 μmol/l per mg ( − 6 %); P= 0·384). Serum MZ increased significantly in Group 1 (0·0094 μmol/l (absolute value); P= 0·015), Group 2 (0·005 μmol/l per mg; P< 0·001) and Group 3 (0·004 μmol/l per mg; P< 0·001). The formulation containing all three macular carotenoids (Group 2 supplement) was the most efficacious in terms of achieving the highest combined concentration of the three MP constituent carotenoids in serum, thereby potentially optimising the bioavailability of these compounds for capture by the target tissue (retina).

Abstract Background The continuation of anti-vascular endothelial growth factor (anti-VEGF) treatment after achieving stability in patients with neovascular age-related macular degeneration has generally been advocated. In our own patients, we thought to assess whether continued anti-VEGF treatment is capable of preventing recurrences. Methods In this retrospective observational case series, patients with stable disease either opted to continue treatment every 12–14 weeks (Group 1) or stopped treatment with subsequent follow-up visits every 8–12 weeks (Group 2). Results Of the 103 eyes of 103 patients achieving stability, 49 eyes continued treatment (Group 1), whereas treatment was stopped in 54 eyes undergoing regular follow-up (Group 2). Recurrent disease was observed in 21 (42.9%) and 33 (61.1%) cases in Group 1 and Group 2, respectively (p = 0.08). Time between achieving stable disease and recurrence was comparable between Group 1 and Group 2 (11.1 ± 8.2 months vs. 9.2 ± 6.7 months; p = 0.43). The number of visits between achieving stability and disease recurrence was similar, but not the number of injections (3.5 ± 2.0 vs. 0.2 ± 0.4; p < 0.001). Conclusions Continuing anti-VEGF therapy after achieving functional and morphological stability every 12–14 weeks does not prevent recurrences. Patients deserve to be informed of a potential lifetime risk of recurrences, even under continued therapy.

Introduction. The objective of the study is to report 4-year treatment outcome with intravitreal Aflibercept injections for neovascular age-related macular degeneration (nAMD) as first life therapy in real-life. Patients and Methods. This is a prospective, monocenter, observational case series analysis. Data from treatment-naïve patients with nAMD with at least 4 years of follow-up were included in the analysis. Data including age, gender, and visual acuity measured on Early Treatment of Diabetic Retinopathy Study charts (ETDRS) and injection numbers were recorded. Spectral domain optical coherence tomography (SD-OCT) data at baseline, month 3, month 6, month 12, year 2, 3, and 4 were also recorded. Patients were treated with a modified treat and extend (T&E) regimen. Results. Of the 48 eyes with nAMD treated, only 31 eyes were available at the 4-year follow-up. The mean age was 81 ± 8 years. The VA gain was 7.3 ± 12.7 letters at 1 year 6.5 ± 12.5 letters at 2 years, VA gain 5.2 ± 17 letters at 3 years, and 6.2 ± 18.6 letters at 4 years. The reduction of central retinal thickness was 118 ± 187 μm at 4 years. Complete resolution of fluid was obtained in 18/31 eyes. The total number of injections was 5.7 ± 2.0 during the first year, 2.9 ± 2.9 during the second year, 3.5 ± 3.3 during the third year, and 4.0 ± 3.4 during the fourth year. The total number of injections was 16 ± 10.6, ranging from 3 to 52 injections. Ten eyes developed macular atrophy over the 4-year period. Conclusion. The results suggest that good long-term morphological and functional outcome can be achieved using Aflibercept in clinical setting.

Design: prospective non-randomized experimental longitudinal cohort study. The aim of the study: to evaluate the visual acuity after phacoemulsification in patients with the “wet” form of age-related macular degeneration, treated by intravitreal angiogenesis inhibitor injections. Materials: 48 patients (48 eyes) with the “wet” form of AMD, treated by intravitreal angiogenesis inhibitor injections, and incipient cataract. All eyes in the study had a diagnosis of “wet” AMD and underwent cataract surgery. They were followed for a minimum of two years after the cataract surgery. The mean age of patients was 78.16 ± 5 years. There were 36 female (75 %) and 12 male (25 %) patients. Results: All patients were retrospectively divided into two groups. Group No. 1 consisted of 23 patients — operated within a year of the diagnosis of “wet” AMD, and group No. 2 which consisted of 25 patients who had a diagnosis of “wet” AMD for longer than one year prior to the cataract surgery. The mean preoperative visual acuity in the 1st group was 0.16 ± 0.07 (median 0.15), and in patients of group 2 — 0.23 ± 0.06 (median 0,2). Mean visual acuity immediately before surgery in the 1st group was 0.13 ± 0.04 (median 0.09), in the 2nd group — 0.12 ± 0.04 (median 0,08). After surgery, in the 1st group, mean visual acuity was — 0.28 ± 0.08 (median 0.25), in the 2nd group —0.18 ± 0.07 (median 0,15). The difference between the two groups was statistically significant, p < 0.01, t-test. Statistically significant visual acuity increase after surgery was registered in both groups and was preserved after one and two years, when compared to the data before surgery: for the 1st group — 0.13 and 0.1; for the 2nd group — 0,1 and 0.07, respectively (p < 0,01, Wilcoxon criterion). Conclusions: Phacoemulsification is reasonable for eyes with the “wet” form of age-related macular degeneration. Patients with shorter “wet” AMD duration obtain a higher visual acuity increase after cataract surgery. Statistically significant visual acuity increase after surgery is preserved in the majority of patients during next 2 years of follow-up.

Abstract Background To compare the outcome of vitrectomy, subretinal tissue plasminogen activator (TPA), and gas with and without subretinal air versus Intravitreal TPA and gas in the treatment of sub macular haemorrhage (SMH) due to Neovascular age related macular degeneration Methods We analysed the notes of 29 cases presented with SMH in the period between 01/2016 and 09/2018 in James Cook University Hospital. Presenting visual acuity (BCVA), size and location of SMH, Procedure done, final BCVA at 6 months and any surgical complications were recorded. 11 Cases (Group 1) received intravitreal TPA (50ug in 0.1 ML), 0.3 ml of pure SF6. 18 cases (Group 2) received 23 G Pars Plana vitrectomy, Subretinal TPA injection (25ug in 0.1 ml), and 20% SF6 gas filling. Group 2 was further divided into 2A (10 patients) who received only subretinal TPA and group 2B (8 patients) who received additional 0.1 ml subretinal air.Results The mean BCVA at presentation was 0.0068 in group 1 and 0.0067 in group 2 (p= 0.8734). The mean postoperative BCVA at six months was 0.31 in group 1 and 0.58 in group 2 (p=0.0015). Subgroup analysis of group 2 didn’t show statistically significant difference in outcome when adding subretinal air to the vitrectomy procedure (p=0.7009).Conclusion Vitrectomy, gas and subretinal TPA has more successful displacement rate and better visual outcome than Intravitreal TPA & Gas alone in treating SMH involving the fovea in AMD. Additional subretinal air doesn't seem to improve the outcome in cases having vitrectcomy.

Purpose. To investigate the association between vision improvement with refractive correction in the visually impaired eyes and the prevalence of ocular comorbidities in the South Korean population. Materials and Methods. The data of 24,620 individuals in the Korea National Health and Nutrition Examination Survey (KNHANES 2009–2011) were reviewed. Visual impairment was defined as a presenting visual acuity < 20/60. The participants with visual impairment in at least one eye were divided into 3 groups according to the best-corrected visual acuity (group 1: <20/30, group 2: ≥20/30 but <20/25, and group 3: ≥20/25). The prevalence of ocular comorbidities was estimated and compared between the three groups. Results. Visual impairment in at least one eye was found in 3031 individuals. Groups 1, 2, and 3 comprised 23.5%, 22.2%, and 54.3% of these visually impaired eyes, respectively. The prevalence of cataract, diabetic retinopathy, age-related macular degeneration, corneal opacity, blepharoptosis, and pterygium was similar to or even higher in group 2 compared to group 1. The prevalence of glaucoma and age-related macular degeneration was 5.40% and 11.39%, respectively, in group 2 and 3.31% and 3.76%, respectively, in group 3. Conclusions. Appropriate ophthalmologic examination is necessary even if people exhibit vision improvement after optical correction.

Purpose. To compare the functional and anatomical outcomes of one dose and three loading doses followed by the pro re nata (PRN) regimen in Chinese neovascular age-related macular degeneration (nvAMD) (including polypoidal choroidal vasculopathy (PCV)) patients. Methods. In this multicenter, prospective, open-label, controlled, 12-month study (ClinicalTrials.gov: NCT02810808), patients were randomized (1 : 1) to 1 dose + PRN (PRN group) or 3 loading doses + PRN (LD group) using intravitreal ranibizumab treatment. Best-corrected visual acuity (BCVA) and central retinal thickness (CRT) were evaluated. The main outcome was the change in BCVA. The noninferiority limit was 5 letters. Results. Forty-five patients in the PRN group and 49 patients in the LD group finished 12-month follow-up. Each group included 4 PCV patients. The mean change in BCVA from baseline was 7.8 letters in the PRN group, compared with 10.9 letters in the LD group (P=0.344). There were no significant differences between two groups in the mean change of CRT (−159.3 μm vs. −120.5 μm) at month 12. The mean number of injections during the 12-month follow-up was 6.0 in the PRN group and 6.8 in the LD group. The proportion of patients who gained an improvement in visual acuity by 15 or more letters was 28.9% in the PRN group and 44.9% in the LD group (P=0.066). Conclusion. One dose + PRN showed noninferior visual gains than 3 loading doses + PRN regimen using ranibizumab in Chinese nvAMD and PCV patients. Number of injections in the PRN group was similar as that in the LD group but remained a potential risk of vision instability during one-year follow-up using OCT-guided retreatment criteria. This trial is registered with NCT02810808.
