Background: Age-related macular degeneration (AMD), a condition of multifactorial origin, is a major cause of irreversible vision loss in industrialized countries. The dry late stage of the disease, known as geographic atrophy (GA), is characterized by progressive loss of photoreceptor cells and retinal pigment epithelial cells in the central retina. An estimated 300 000 to 550 000 people in Germany suffer from GA.

Povidone-iodine (PI) is the standard antiseptic for intravitreal injections (IVIs), while chlorhexidine (CHX) is a potential alternative. The efficacy of PI versus CHX in preventing endophthalmitis remains debated, with studies showing mixed results. To compare the effectiveness of using PI compared with CHX in IVI procedures regarding endophthalmitis rates, culture-positive endophthalmitis rates, and changes in visual acuity.

Background: Ozurdex® (Allergan®, AbbVie Company, North Chicago, Illinois, EUA), is composed of 0.7 mg of dexamethasone, fused in a solid biodegradable PLGA polymer, whose degradation occurs naturally in the vitreous cavity, usually in six months after its application.
Methods: In this study, we included patients aged ≥ 18 years with one or two eyes who had an indication for Ozurdex implants.

The abrupt and substantial elevation of intraocular pressure (IOP) in acute glaucoma induces retinal ischemia/reperfusion (I/R) injury, resulting in progressive retinal ganglion cell (RGC) death and irreversible visual impairment. PANoptosis, a form of regulated cell death consisting of pyroptosis, apoptosis and necroptosis, is reported to be involved in high IOP-induced RGC death. However, the precise mechanisms of RGC death remain unclear, and neuroinflammation is considered to play a vital role.

Background: To evaluate the efficacy and safety of intravitreal injections of 4 mg (high dose) of aflibercept in treatment-naive patients with neovascular AMD(nAMD) with treat and extend(TREX) dosing regimens, and to determine the frequency of injections.
Methods: In this interventional, retrospective study a total of 15 eyes of 14 patients (eight female and 9 male) with nAMD were included. All patients were examined and OCT imaging was performed at the time of initial presentation, on the day of each injection and at subsequent follow-up visits.
