AIM: Conventional eyedropper-delivered volumes (25-50 µl) exceed the eye's usual tear-film volume (7 µl) and precorneal reservoir capacity, risking overflow and ocular/systemic complications. Piezoelectric high-precision microdosing may circumvent these limitations. Results & methodology: In this masked, nonrandomized, cross-over study, subjects (n = 12) underwent pupil dilation with topical phenylephrine (PE) administered by 32-µl eyedropper (2.5% or 10% formulation) and 8-µl electronic microdosing (10% formulation)...

PURPOSE: About 70% of eye drops contain benzalkonium chloride (BAK) to maintain sterility. BAK is an effective preservative but it can cause irritation and toxicity. We propose to mitigate ocular toxicity without compromising sterility by incorporating a filter into an eye drop bottle to selectively remove BAK during the process of drop instillation. METHODS: The filter is a packed bed of particles made from poly(2-hydroxyethyl methacrylate) (pHEMA), which is a common ophthalmic material...

In the present study, we designed and synthesized a hydrogelator comprised of ibuprofen (IPF) and GFFY peptide linked through a cleavable ester bond. We found that the synthesized hydrogelator could spontaneously self-assemble into a hydrogel under a heating-cooling process. When the hydrogel was acted upon by an esterase, IPF was released in a sustained manner. Moreover, the hydrogel had significantly elevated anti-inflammatory efficacy, compared with IPF, in RAW264.7 macrophages. The hydrogel showed good cytocompatibility, as well as excellent ocular biocompatibility when instilled topically...

Control of the important poultry pathogen Mycoplasma gallisepticum is highly dependent on safe and efficacious attenuated vaccines. In order to assess a novel vaccine candidate we evaluated the safety and efficacy of the M. gallisepticum mutant 26-1. The oppD1 gene in this mutant has been interrupted by a signature-tagged transposon and previous studies have shown that it can colonise the respiratory tract of chickens without inducing significant disease. The capacity of the oppD1 mutant to induce protective immunity in the respiratory tract after vaccination by eye-drop was assessed by challenging vaccinated birds with an aerosol of the virulent M...
