Background/Objectives: Age-related macular degeneration (AMD) is one of the main causes of blindness and visual impairment worldwide. Intravitreal complement inhibitors are an emergent approach in the treatment of AMD, which have had encouraging results. This systematic review analyzes the outcomes and safety of complement inhibitor therapies for GA in AMD cases. Methods: A comprehensive search on the PubMed and Web of Science databases returned 18 studies involving various complement inhibitor agents, with a total of 4272 patients and a mean follow-up of 68.2 ± 20.4 weeks. Results: Most treated patients were white (96.8%) and female (55.8%), with a mean age of 78.3 ± 7.8 years and a mean GA area of 8.0 ± 3.9 mm². There were no differences in visual function change between treated and control participants. The mean GA area change was 2.4 ± 0.7 mm² in treated participants vs. 2.7 ± 0.8 mm² in control groups (p < 0.001). The ocular and systemic side effects were similar to those of intravitreal anti-VEGF. A less-understood effect was that of the onset of choroidal neovascularization (CNV) in 1.1–13% of patients; this effect was found to be more frequent in patients with neovascular AMD in the fellow eye or nonexudative CNV in the study eye at baseline. Conclusions: Complement inhibitors may represent a useful therapy for GA in AMD, but a personalized approach to patient selection is necessary to optimize the outcomes.

Given the current global circumstances, marked by severe environmental pollution—including the contamination of food—along with daily stress and a sedentary lifestyle, many consumers choose to improve their quality of life by using, among others, minimally processed food, food supplements, and gemmo-derivatives. Recent lab and clinical studies have shown the positive impact of specific nutrients with antioxidant capacities in the treatment of several conditions generated by oxidative stress. This paper reviews antioxidant plant extracts utilized as components in various dietary supplements and gemmoderivatives, highlighting their chemical composition and biological properties in preventing diseases caused by oxidative stress. A modern approach to food science brings to the fore the concept of dietary supplements vs. functional food, nutraceuticals, and gemmo-derivatives. The definitions of these terms are not being unanimously regulated in this respect and describe each category of compound and product, also emphasizing the need to implement adequate nutrivigilance. In order to enhance the absorption and bioavailability of dietary supplements and gemmo-derivatives based on antioxidant plant extracts, some encapsulation techniques are outlined.

Background: Macular telangiectasia (MacTel), also known as idiopathic juxtafoveolar telangiectasis (IJFTs), involves telangiectatic changes in the macular capillary network. The most common variant, MacTel type 2, has distinct clinical features and management strategies. Methods: This study offers a comprehensive review of MacTel and focuses on a series of three patients diagnosed with MacTel type 2 in our clinic. A meticulous ophthalmological evaluation, augmented by high-resolution imaging techniques like optical coherence tomography (OCT), OCT angiography (OCT-A), fundus autofluorescence (FAF), fluorescein angiography (FA), and adaptive optics (AOs) imaging, was conducted. Results: The findings revealed normal anterior segment features and a grayish discoloration in the temporal perifoveal area on fundus examination. OCT exhibited hyporeflective cavities in the inner and outer neurosensory retina, along with other changes, while OCT-A identified retinal telangiectatic vessels in the deep capillary plexus. FAF demonstrated increased foveal autofluorescence, while FA initially detected telangiectatic capillaries followed by diffuse perilesional leakage in the later phase. Adaptive optics images showed the cone mosaic pattern. Notably, one patient developed a macular hole as a complication, which was successfully managed surgically. Conclusion: This study underscores the challenges in diagnosing and managing MacTel, emphasizing the importance of a multidisciplinary approach and regular follow-ups for optimal outcomes.
