To date, ocular injections and implants are the most effective methods for drug delivery to the back of the eye. However, invasive delivery methods also are costly and risky due to possible complications. In this paper, a novel proprietary polyacetylene polymer and two cell penetrating peptides are compared for topical drug delivery to treat retinal diseases.

Examining the link between retinal function and structure in ocular hypertension is crucial for glaucoma research. The rat magnetic microbead model, mimicking glaucoma aspects, provides insights into this relationship. The study aims to examine if behavioral, functional, and morphological parameters have correlation in the rat magnetic microbead glaucoma model.​

Streptozotocin (STZ) induced hyperglycemic rats, commonly used in preclinical diabetic retinopathy (DR) research, have poor response to the most used laboratory rodent anesthesia such as medetomidine/ketamine mixture (MK), and are prone to develop various welfare issues. The purpose of this study was to compare medetomidine/midazolam/butorphanol anesthesia (MMB) to MK in the STZ induced DR rat model to validate injectable anesthesia with less side effects and faster recovery time without compromising the DR development.
