Ocular Drug Delivery
Open accessAbstract
Ocular drug delivery has been a major challenge to pharmacologists and drug delivery scientists due to its unique anatomy and physiology. Static barriers (different layers of cornea, sclera, and retina including blood aqueous and blood-retinal barriers), dynamic barriers (choroidal and conjunctival blood flow, lymphatic clearance, and tear dilution), and efflux pumps in conjunction pose a significant challenge for delivery of a drug alone or in a dosage form, especially to the posterior segment. Identification of influx transporters on various ocular tissues and designing a transporter-targeted delivery of a parent drug has gathered momentum in recent years. Parallelly, colloidal dosage forms such as nanoparticles, nanomicelles, liposomes, and microemulsions have been widely explored to overcome various static and dynamic barriers. Novel drug delivery strategies such as bioadhesive gels and fibrin sealant-based approaches were developed to sustain drug levels at the target site. Designing noninvasive sustained drug delivery systems and exploring the feasibility of topical application to deliver drugs to the posterior segment may drastically improve drug delivery in the years to come. Current developments in the field of ophthalmic drug delivery promise a significant improvement in overcoming the challenges posed by various anterior and posterior segment diseases.

“This method avoids complications of first-pass metabolism and has the advantage of easy administration, sometimes by the patients themselves. However, barriers, such as the pre-corneal tear film, the structure of the cornea, limited volume, lacrimal drainage system, reflex tearing, and aqueous outflow of the eye, reduce the bioavailability of the product to around 5% or less.35,118,119”

“Most gene therapy viral vectors given intravitreally, fail to adequately transduce photoreceptors and RPE, due to the inner limiting membrane that divides the vitreous from the retina.1,15,119,127”

In the citing paper
“Despite these advantages, intravitreal injections also carry risks of adverse reactions, including inflammation, endophthalmitis, increased intraocular pressure, retinal detachment, hemorrhage, and cataracts, and due to the repeated use of these injections in various treatments, patient compliance can become an issue.119,127,129”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
