Liposomal Drug Delivery in Ocular Therapy: Strategies for Enhancing Corneal Penetration and Bioavailability.
Review in Cells, 2026. 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
Vision impairment affects approximately 2.2 billion people worldwide, with glaucoma, age-related macular degeneration, fungal keratitis, and diabetic retinopathy among the leading causes of preventable blindness. Effective pharmacotherapy remains severely constrained by the eye's multilayered barrier architecture. Tear film, the corneal epithelium, the blood-aqueous barrier, and the blood-retinal barrier collectively restrict conventional topical drug bioavailability to less than 5% of the administered dose. Liposomal drug delivery systems have emerged as a clinically translatable platform capable of overcoming these barriers through targeted surface modification. This review provides a brief introduction to ocular barriers to drug delivery and transport and critically examines numerous surface-modification strategies applied to liposomal carriers to enhance corneal permeation and ocular bioavailability of drugs. It highlights the advantages and disadvantages of each modification strategy, as well as the convergent mechanism of liposomal surface modification in overcoming ocular barriers, and provides a comparative analysis of different surface-modification strategies of liposomes in terms of safety, efficacy and corneal retention. Additionally, it describes challenges associated with liposomal ophthalmic formulations in industrial scaling up. The review also sheds light on some FDA-approved liposomal ophthalmic products, active clinical trials on liposomal formulations, and relevant patents, demonstrating the potential benefits of liposomal drug delivery in the treatment of ocular disorders.
