Glaucoma is an irreversible progressive optic neuropathy, for which the major proven treatment is to lower the intraocular pressure (IOP). Five groups of IOP-lowering eye drops have varying mechanisms of action. Some drops, such as β-blockers and α-2 agonists, have potentially serious systemic side effects. ⋯ Improvements in drug delivery are on the horizon. Drug-eluting devices and implants are able to deliver the drug closer to the receptors for an extended period of time. This will improve treatment adherence and efficacy, which are major limitations with current medical therapy.

To assess the factors that contributed to the successful completion of recruitment for the largest clinical trial ever conducted in Australia, the Aspirin in Reducing Events in the Elderly (ASPREE) study. ⋯ General practice can be a rich environment for research when barriers to recruitment are overcome. Including regional GPs and focusing efforts in areas with the highest proportions of potentially eligible participants improves recruitment. The success of ASPREE attests to the clinical importance of its research question for Australian GPs.

Cholinesterase inhibitors (ChEIs) and memantine are medications used to treat the symptoms of specific types of dementia. Their benefits and harms can change over time, particularly during long term use. Therefore, appropriate use of ChEIs and memantine involves both prescribing these medications to individuals who are likely to benefit, and deprescribing (withdrawing) them from individuals when the risks outweigh the benefits. We recently developed an evidence-based clinical practice guideline for deprescribing ChEIs and memantine, using robust international guideline development processes. ⋯ Deprescribing ChEIs and memantine through shared decision making with individuals and their caregivers by: ▶determining their treatment goals; ▶discussing benefits and harms of continuing and ceasing medication, from the start of therapy and throughout; and ▶engaging them in monitoring after discontinuation, while informing carers that the individual will continue to decline after discontinuation. This approach may reduce adverse drug reactions and medication burden, leading to improved quality of life in people with dementia.
