Fungal keratitis is a globally blinding eye disease caused by fungi, with more than 1.05 million cases diagnosed annually, mainly in Asia. It the most common form of infectious keratitis, accounting for approximately 40–50% microbial cases. The difficult to treat and prognosis often poor. Conventional antimicrobial therapies, which are mainstay treatment, face problems off-target toxicity, low bioavailability, drug-resistant fungi. In recent years, novel drug delivery systems have emerged as promising alternative. These improve stability, extend residence time, control release, target specific tissues cells, reduce toxic side effects. Nanoparticle-based particularly compelling. aim this paper elucidate mechanisms advances nanoparticle-based antifungal therapy provide new perspectives on treatment fungal keratitis.

Abstract Despite the existence of numerous eye drops in market, most them are not sufficiently effective because quick clearance and barriers within eye. To increase delivery drugs to eye, various new formulations have been explored recent decades. These aim enhance drug retention penetration, while enabling sustained release over extended periods. One such innovative approach is utilization contact lenses, which were originally designed for cosmetic purposes vision correction. Contact lenses appeared as a promising formulation ocular delivery, they can bioavailability diminish unwanted side effects. They specifically appropriate treating chronic conditions, making an area interest researchers field ophthalmology. This review outlines potential nanomaterial-laden diagnosis treatment glaucoma.

The special structure of eyes and the existence various physiological barriers make ocular drug delivery one most difficult problems in pharmaceutical field. Considering patient compliance, local administration remains preferred method anterior part eyes. However, suffers from poor bioavailability, need for frequent administration, systemic toxicity. Administration posterior eye is more difficult, intravitreal injection often used. But faces compliance likely side effects after multiple injections. development nanocarrier technology provides an effective way to solve these problems. Among them, liposomes, as widely used carrier clinical application, have characteristics amphiphilic nanostructure, easy surface modification, extended release time, good biocompatibility, etc. liposomes are expected overcome obstacles effectively deliver drugs target site improve bioavailability. This review summarized controllable properties well application research progress diseases. In addition, we routes contained eyes, prospects treatment
