AbstractThe delivery of drugs to the posterior segment of the eye remains a tremendously difficult task. Prolonged treatment in conventional intravitreal therapy requires injections that are administered frequently due to the rapid clearance of the drug molecules. As an alternative, intraocular implants can offer drug release for long-term therapy. However, one of the several challenges in developing intraocular implants is selecting an appropriate in vitro dissolution testing model. In order to determine the efficacy of ocular implants in drug release, multiple in vitro test models were emerging. While these in vitro models may be used to analyse drug release profiles, the findings may not predict in vivo retinal drug exposure as this is influenced by metabolic and physiological factors. This review considers various types of in vitro test methods used to test drug release of ocular implants. Importantly, it discusses the challenges and factors that must be considered in the development and testing of the implants in an in vitro setup. Graphical abstract

✓ The author describes a technique for directly closing a carotid cavernous fistula with electrothrombosis while preserving the intracranial arterial circulation. Copper wires are introduced through the superior ophthalmic vein or a frontotemporal craniotomy, and thus directly into the portion of the sinus into which the fistula drains; if posterior, into the posterior segment of Parkinson's triangle, if inferior, into the pterygoid plexus, and if anterior, through the sphenoparietal sinus and/or middle cerebral vein to the anterior-inferior portion of the sinus. A direct current is applied until a thrombus is confirmed angiographically and the wires are left in place. Four patients treated by this method are presented.
