In the field of ophthalmology, central retinal artery occlusion is still one of the unsolved pathologies, as there is no widely accepted evidence-based therapeutic concept. Meta-analysis suggests that intravenous fibrinolysis might help to improve the outcome if performed within the first 4.5 hours after symptom onset. However, this short window of opportunity is often missed due to delays during diagnostic testing (e.g. time elapsed before performance of an ophthalmological examination) or patient-processing (referring the patient to a specialized medical facility). This article presents a diagnostic tool in the form of a simple questionnaire, comprising a medical history and examinations, which could help to minimize the time required to initiate the appropriate treatment.

Unlocking the potential for optic nerve regeneration over long distances: a multi-therapeutic intervention.

Retinal ganglion cells (RGCs) generally fail to regenerate axons, resulting in irreversible vision loss after optic nerve injury. While many studies have shown that modulating specific genes can enhance RGCs survival and promote optic nerve regeneration, inducing long-distance axon regeneration through single-gene manipulation remains challenging. Nevertheless, combined multi-gene therapies have proven effective in significantly enhancing axonal regeneration.

The effect of the Rho-kinase inhibitor ripasudil on the retinal optic nerve fiber layer (RNFL) remains unclear. We aimed to determine this effect in patients with primary open-angle glaucoma (POAG) using optical coherence tomography (OCT) measurements and linear mixed analysis. This study prospectively included outpatients from a single center with POAG without a history of vitreoretinal or glaucoma surgery from December 2014 to June 2020, in whom the circumpapillary RNFL thickness (cpRNFLT) was measured more than three times before and after ripasudil initiation, without additional medication or surgery during the period.

Purpose: To compare the anatomical and visual outcomes in eyes with submacular hemorrhage (SMH) treated with a combination of ranibizumab (RBZ) either innovator or biosimilar (Razumab) and intravitreal perfluoropropane gas (CF).
Methods: Treatment naïve neovascular age related macular degeneration (n-AMD) patients with SMH were retrospectively analyzed. Patients received either innovator or biosimilar RBZ (3 loading doses followed by pro re nata regimen) and single injection of intravitreal CF.
Fluid fluctuations assessed with artificial intelligence during the maintenance phase impact anti-vascular endothelial growth factor visual outcomes in a multicentre, routine clinical care national age-related macular degeneration database.

Aim: To evaluate the impact of fluid volume fluctuations quantified with artificial intelligence in optical coherence tomography scans during the maintenance phase and visual outcomes at 12 and 24 months in a real-world, multicentre, national cohort of treatment-naïve neovascular age-related macular degeneration (nAMD) eyes.
Methods: Demographics, visual acuity (VA) and number of injections were collected using the Fight Retinal Blindness tool. Intraretinal fluid (IRF), subretinal fluid (SRF), pigment epithelial detachment (PED), total fluid (TF) and central subfield thickness (CST) were quantified using the RetinAI Discovery tool.
Evaluation of Tele-Education in Malawi for Detection of Macular Features Using Optical Coherence Tomography.

Department of Ophthalmology, University Hospital Tübingen, Germany.
Purpose: The study aimed to assess the reliability of tele-education in training a Malawian ophthalmology resident to interpret optical coherence tomography (OCT) images of patients with macular conditions.
Methods: This was a retrospective analysis of 1000 macula-centered OCT image series from 1000 eyes of 1000 consecutive patients from Malawi, which involved initial interpretation by a German retina specialist (observer 1) (T). Observer 1 then trained a Malawian resident (observer 2) via email, and observer 2 independently interpreted images at T, followed by face-to-face training in Malawi and reinterpretation at T and T (3-month intervals).
