Topical Application of RNAi Therapy Using Surface-Modified Liposomes for Treating Retinal-Vein Occlusion.
Article in Molecules (Basel, Switzerland), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Retinal diseases can result in blindness and visual impairment. They represent a significant medical burden and adversely affect life expectancy. Recently, antibody- and nucleic acid-based pharmaceuticals have increasingly been used to treat retinal diseases, with improvement or cure as the goal; however, these drugs are currently only administered by intravitreal injection. In this study, we present a novel approach to treating retinal diseases using eye drops that contain PnkRNA, a single-stranded RNA nucleic acid. PnkRNA-loaded liposomes were shown to effectively deliver retinal drugs and significantly inhibit retinal thickening in a mouse retinal-vein occlusion model. Cationic modification of the liposome surface enhanced the delivery of nucleic acids and therapeutic efficacy. Moreover, to reduce the frequency of eye-drop administration, liposomes were incorporated into the thermoresponsive gels. This formulation provided sustained retinal delivery and exhibited superior therapeutic efficacy compared with liposomal eye drops. This nucleic acid retinal delivery technology represents a significant advancement in drug-delivery technology, offering a safe and simple treatment for retinal diseases.
