Background: With this study, we investigate the short-term clinical outcomes of patients affected by diabetic macular edema (DME) after switching to intravitreal Faricimab (IVF) in a real-world setting. Methods: We conducted a retrospective chart review on all patients treated for DME with IVF who showed insufficient responses to prior anti-VEGF therapy. Data collected included baseline patient demographics, medical history, best-corrected visual acuity (BCVA), central retinal thickness (CRT) and central retinal volume (CRV). We analyzed functional and structural measures before and after IVF, compared baseline demographics and treatment factors between Faricimab-responders and reduced-responders and assessed influencing factors of the follow-up BCVA and CRT. Results: This study included 25 eyes from 16 patients. After switching to IVF, the mean BCVA showed no significant improvement, changing from 59.4 ± 13.4 Early Treatment of Diabetic Retinopathy Study (ETDRS) letters at baseline to 61.4 ± 12.8 ETDRS letters at follow-up (p = 0.26). CRT significantly reduced from 414.4 ± 126.3 µm to 353.3 ± 131.1 µm (p < 0.011), and the 3 mm CRV significantly decreased from 2.8 ± 0.5 mm3 to 2.6 ± 0.6 mm3 (p < 0.012). Seven patients met the responder criteria, exhibiting an improvement of at least 5 ETDRS letters and a simultaneous CRT reduction of at least 30 µm. Further analysis showed that higher BCVA at baseline (p < 0.001) was associated with better BCVA following IVF, while higher baseline CRT (p < 0.003), a higher number of prior anti-VEGF agents (p < 0.034) and prior corticosteroid injections (p < 0.019) were associated with greater CRT at follow-up. Conclusions: Following the initial IVF injection series, we observed a clear improvement of anatomical measures. No functional improvement was observed, although visual acuity remained stable. Higher baseline BCVA was associated with better post-IVF BCVA, while higher baseline CRT, a greater number of prior anti-VEGF agents and prior corticosteroid injections were linked to higher CRT post-IVF.

UNASSIGNED: Limited data is available on treatment satisfaction with the management of wet age-related macular degeneration (wAMD) among patients in Italy. In this cross-sectional real-world study, treatment satisfaction with anti-vascular endothelial growth factor (anti-VEGFs) was assessed in patients with wAMD in Italy.
UNASSIGNED: This was a non-interventional, cross-sectional survey involving patients with wAMD receiving anti-VEGFs. The survey was administered through a virtual assistant via phone. Patients\' treatment satisfaction was assessed using a newly developed Novartis Tailored Treatment Satisfaction Questionnaire (NVS TTSQ) and the validated Macular Disease Treatment Satisfaction Questionnaire (MacTSQ).
UNASSIGNED: Overall, 154 evaluable patients were enrolled in 5 centers across Italy. The mean (SD) age of the patients was 76.8 years (7.01). Overall treatment satisfaction score assessed by NVS TTSQ was 40.50 (7.11), with a mean of 9.97 (1.84) on the information domain and 22.98 (4.57) on the unmet need domain. Patients were satisfied with diagnosis communication (4.99 [1.30]), information provided on treatment administration (4.58 [1.49], range 0-6), the waiting room (4.40 [1.43]), and management of visits and injections at the center (5.14 [1.12]), general management of maculopathy at the center (5.22 [1.01]). Patients were not satisfied with their independence in terms of disease management (2.56 [2.45]); they would like additional information about the disease (5.38 [1.03]) and to discuss the injection procedures (4.02 [1.94]) with already-treated patients. The overall treatment satisfaction score on MacTSQ scale was 55.84 (10.13).
UNASSIGNED: Patients with wAMD are satisfied with the overall management of their disease in Italy. However, patients would like to have more information on prognosis and management of the disease.

UNASSIGNED: To evaluate the responses of different optical coherence tomography (OCT) patterns of diabetic macular edema (DME) to intravitreal injection therapy.
UNASSIGNED: In this retrospective, comparative, and multicenter study, patients who had previously untreated DME, who received intravitreal ranibizumab (IVR) or aflibercept (IVA) and/or steroid treatment with the pro re nata (PRN) treatment regimen after a 3-month loading dose, and had a 12-month follow-up in the MARMASIA Study Group were included. Morphological patterns of DME were divided into four groups based on OCT features diffuse/spongious edema (Group 1), cystoid edema (Group 2), diffuse/spongious edema+subretinal fluid (SRF) (Group 3), and cystoid edema+SRF (Group 4). Changes in central macular thickness (CMT) and best-corrected visual acuity (BCVA) at months 3, 6, and 12, and the number of injections at month 12 were compared between the DME groups.
UNASSIGNED: 455 eyes of 299 patients were included in the study. The mean baseline BCVAs [Logarithm of the Minimum Angle of Resolution (logMAR)] in groups 1, 2, 3, and 4 were 0.54 ± 0.24, 0.52 ± 0.25, 0.55 ± 0.23, and 0.57 ± 0.27, respectively. There was no significant difference between the baseline mean BCVAs between the groups (p = .35). The mean BCVAs were significantly improved to 0,47 ± 0,33 in group 1, 0,42 ± 0,33 in group 2, 0,47 ± 0,31 in group 3, and 0,45 ± 0,43 at month 12. There was no significant difference between the groups in terms of BCVA change at month 12 (p = .71). The mean baseline CMTs in groups 1, 2, 3, and 4 were 387,19 ± 128,19, 447,02 ± 132,39, 449,12 ± 109,24, and 544,19 ± 178,61, respectively. At baseline, the mean CMT was significantly higher in Group 4 than in the other groups (p = .000). The mean CMTs were significantly decreased to 325,16 ± 97,55, 334,94 ± 115,99, 324,33 ± 79,20, and 332,08 ± 150,40 in four groups at month 12 respectively (p > .05). The groups had no significant difference in mean CMT at month 12 (p = .835). The change in CMT was significantly higher in Group 4 than in the other groups at month 12 (p = .000). The mean number of intravitreal anti-VEGF injections at month 12 was 4.51 ± 1.57 in Group 1, 4.63 ± 1.54 in Group 2, 4.88 ± 1.38 in Group 3, and 5.07 ± 1.49 in Group 4. The mean number of anti-VEGF injections in Group 1 and Group 2 was significantly lower than in Group 4 (p = 0,014 and p = 0,017).
UNASSIGNED: In real life, there was no significant difference between the DME groups in terms of visual improvement at month 12. However, better anatomical improvement was achieved in Group 4 than in the other DME groups.

Diabetic macular edema (DME) is a serious vision-threatening complication that can arise at any stage of diabetic retinopathy. Primary treatment involves anti-vascular endothelial growth factor (VEGF) agents, which are highly effective but associated with challenges, such as the need for frequent injections, relapses, and resistance to therapy. Therefore, there has been a growing interest in developing new treatments that offer similar or superior outcomes in DME. This review article explores emerging treatments, including WNT agonists, gene therapy, protein inhibitors, and, most importantly, the first-ever non-invasive and oral drugs. The evolving therapies in diabetic retinopathy offer hope for continued improvement in vision loss associated with one of the most common chronic conditions worldwide.

As spaceflight becomes increasingly accessible and expansive to humanity, it is becoming ever more essential to consider the treatment of various eye diseases in these challenging environments. This paper delves into the increasing fascination with interplanetary travel and its implications for health management in varying environments. It specifically discusses the pharmacological management of ocular diseases, focusing on two key delivery methods: topical eye drops and intravitreal injections. The paper explores how microgravity impacts the administration of these treatments, a vital aspect in understanding drug delivery in space. An extensive analysis is presented on the pharmacokinetics of eye medications, examining the interaction between pharmaceuticals and ocular tissues in zero gravity. The goal of the paper is to bridge the understanding of fluid dynamics, microgravity and the human physiological systems to pave the way for innovative solutions faced by individuals in microgravity.

Age-related macular degeneration (AMD) is the leading cause of irreversible blindness worldwide and a severe medical and social problem. The steadily increasing number of patients is related to the aging of the population. So far, many factors affecting the development of AMD have been identified, which can be divided into non-modifiable, including genetic factors, age, and sex, and modifiable or environmental factors, such as smoking, poor diet, and hypertension. Early stages of age-related macular degeneration are characterized by fundus drusen and abnormalities in the retinal pigment epithelium. In late stages, geographic atrophy and choroidal neovascularization (CNV) are observed. The treatment of AMD, especially its advanced forms, is very challenging. Intensive research has made it possible to treat advanced stages of the dry form of AMD with pegcetacoplan and avacincaptad pegol, new drugs approved for use in the US. Pegcetacoplan targets the C3 and avacincaptad pegol targets the C5, the pivotal proteins of the complement cascade. The drugs are administered by intravitreal injection. The gold standard for neovascular AMD (nAMD) consists of intravitreal injections of anti-vascular endothelial growth factor (anti-VEGF) drugs such as bevacizumab, ranibizumab, aflibercept, brolucizumab, and faricimab. Treatment can be administered according to the fixed, pro-re-nata, and treat-and-extend regimens. The latter seems to have the best effect on improving visual acuity (VA) and the maximum therapeutic benefit. The search continues for the best ways to deliver intravitreal drugs. Current methods include sustained-release implants and hydrogel platforms for drug release, while the most promising future pathways for treating dry and nAMD are stem cell and gene therapy.

OBJECTIVE: To compare the efficacy of brolucizumab and aflibercept treatment in reducing maximum thickness of pigment epithelial detachments (PED) and sub-retinal pigment epithelium (sub-RPE) fluid in patients with neovascular age-related macular degeneration (nAMD) in the HAWK and HARRIER studies.
METHODS: HAWK and HARRIER were 96-week, prospective, randomized, double-masked, controlled, multicenter studies SUBJECTS, PARTICIPANTS, AND/OR CONTROLS: 1,775 patients across 11 countries were included in the HAWK study and 1,048 patients across 29 countries were included in the HARRIER study.
UNASSIGNED: After three monthly loading doses, brolucizumab-treated eyes received injections every 12 weeks (q12w) or q8w if disease activity (DA) was detected. Aflibercept-treated eyes received fixed q8w dosing.
METHODS: Maximum thickness of PED and sub-RPE fluid across the macula were assessed at baseline through Week 96 in the brolucizumab- and aflibercept-treated patients, and in the patient subgroups with DA at Week 16 (matched in terms of injection number and treatment interval).
RESULTS: At Week 96, there were greater mean percentage reductions from baseline in maximum thickness of both PED and sub-RPE fluid in brolucizumab-treated patients versus aflibercept-treated patients (PED: 19.7% [n=336] vs 11.9% [n=335] in HAWK; 29.5% [n=364] vs 18.3% [n=361] in HARRIER. Sub-RPE fluid: 75.4% vs 57.3% in HAWK; 86.0% vs 76.3% in HARRIER). A similar trend in mean percentage reductions was observed in patients with DA at Week 16.
CONCLUSIONS: This analysis shows that brolucizumab achieved greater reductions in PED and sub-RPE fluid thickness than aflibercept in HAWK and HARRIER.

UNASSIGNED: This study aims to examine and compare the effects of intravitreal bevacizumab injection (IVB) at subfoveal 1500 micron (μm) and submacular 6000 μm in patients with diabetic macular edema (DME).
UNASSIGNED: Fifty eyes of 45 patients with DME who completed six doses of IVB were included in the study group, and 50 eyes of 42 patients who had diabetic retinopathy (DR) but did not receive any treatment were included in the control group. Central macular thickness (CMT), central choroidal thickness (CCT), subfoveal and total choroidal area (TCA), and choroidal vascular index (CVI) were calculated and their changes at zero, three and six months were evaluated.
UNASSIGNED: At baseline, CVI was significantly lower in both the subfoveal and total macular areas in the study group (p = 0.004, p = 0.003). In the study group, a significant decrease was observed in CVI between zero and six months in the subfoveal area (p = 0.001). In the submacular area, the decrease in CVI in the study group was significant between zero to three months and zero to six months. There was moderate correlation between measurements of CVI in the subfoveal and total macular areas (r = 0.66, p < 0.001).
UNASSIGNED: These findings indicate that intravitreal bevacizumab injection reduces the CVI and the effects of intravitreal anti-VEGF on CVI emerge earlier and more prominently in the submacular 6000 µm area.

OBJECTIVE: To quantify the long-term impact (24 months) on the visual results and activity of neovascular lesions of COVID-19 confinement in patients with nAMD in our population.
METHODS: A retrospective observational study of patients with nAMD who attended consultation or were treated during the 3 months before confinement was carried out.
RESULTS: 144 patients (168 eyes) with nAMD were included, 51 of them (35.42%) came during confinement, and at 24 months the final cohort was 118 patients (133 eyes). The previous VA of 57.99 ± 23.68 letters decreased, clinically relevant and statistically significant, by an average of 6.87 (±16.84) and 7.89 (±19.58) at 12- and 24-months follow-up. This change differs significantly from the two-year vision change observed in the national database of pretreated patients. The median number of injections and consultations is lower in our group at 12 months, compared to the pre-pandemic national database, and tends to equalize at 24 months. We did not find differences in vision when we compared patients who attended consultations during confinement or in treatment intervals greater than 8 weeks (Tq8w).
CONCLUSIONS: The VA of patients with nAMD decreased significantly after confinement, probably due to the lower number of antiangiogenic injections and consultations during the first year, and did not recover during the second year despite the increase in the number of injections and visits close to those reported before confinement.
