Background: Age-related macular degeneration (AMD) is a progressive neurodegenerative disease of a central part of the neural retina (macula) and a leading cause of blindness in elderly people. While it is known that the AMD is a multifactorial disease, genetic factors involved in lipid metabolism, inflammation, and neovascularization are currently being widely studied in genome-wide association studies (GWAS). The aim of our study was to evaluate the impact of new single nucleotide polymorphisms (SNPs) in , , , and genes on AMD development.
Methods: Case-control study involved 254 patients diagnosed with early AMD, 244 patients with exudative AMD, and 942 control subjects. The genotyping of (rs8017304 and rs2588809), (rs6987702, rs4351379, and rs4351376), (rs13095226), and (rs1064583) was carried out using TaqMan assays by a real-time polymerase chain reaction (RT-PCR) method.
Results: Statistically significant difference was found in genotype (TT, TC, and CC) distribution of rs13095226 between exudative AMD and control groups (60.2%, 33.6%, and 6.1% vs. 64.9%, 32.3%, and 2.9%, respectively, = 0.036). Also, comparing with TT+TC, rs13095226 CC genotype was associated with 3.5-fold increased odds of exudative AMD development (OR = 3.540; 95% CI: 1.415-8.856; = 0.007).
Conclusion: Our study revealed a strong association between a variant in (rs13095226) and exudative AMD development.

Age-related macular degeneration (AMD) is a chronic condition that causes gradual central vision loss, most commonly in patients 50 years or older. This disease is commonly classified as either dry (non-exudative) or wet (exudative). Most patients with AMD have the non-exudative form, characterized by the presence of drusen in the macula.

To present the management and outcomes of a case of acute submacular hemorrhage due to neovascular age-related macular degeneration (nAMD). A single case was retrospectively evaluated. A 79-year-old man with a history of submacular hemorrhage from nAMD and persistent disease activity in the left eye presented with acute submacular hemorrhage in his better-seeing right eye, which was previously closely monitored for an extrafoveal serous pigment epithelial detachment without exudation.

Objective: To retrospectively analyze the etiology of non-diabetic retinopathy (DR) and non-traumatic vitreous haemorrhage (VH), and the effects of different anti-vascular endothelial growth factor (VEGF) drugs.
Methods: A retrospective analysis was conducted on VH patients diagnosed as non-diabetic retinopathy or trauma. Among 101 patients treated with anti-VEGF drugs, there were 48 cases in the Conbercept group and 53 cases in the Ranibizumab group.

In this narrative review we describe the main optical coherence tomography biomarkers appearing in eyes with neovascular age-related macular degeneration (AMD) that do not directly correspond to exudation. We highlight those signs that may mimic exudation and therefore do not require active treatment, such as outer retinal tubulations, pseudocysts, lipid globules, or hyporeflective wedges. Other signs may indicate impending exudation such as hyperreflective foci or shallow irregular retinal pigment epithelium elevation, and therefore should be carefully monitored.
