Vitreoretinal complications and surgical outcomes in patients with X‐linked retinoschisis

Acta Ophthalmologica, EarlyView.
Abstract Purpose X‐linked retinoschisis (XLRS) is an inherited vitreoretinal disorder characterized by macular retinoschisis. In a subgroup of patients, peripheral retinoschisis can occur, potentially leading to complications such as vitreous haemorrhage (VH) and retinal detachment (RD).

Randomized, single‐centre, double‐blinded repeated dose investigation of safety and tolerability of ocular administrations of a novel silica eye drop product in healthy volunteers

Acta Ophthalmologica, EarlyView.
Abstract Purpose Managing ocular diseases often requires frequent eye drop administration, which can challenge patient compliance. A long‐acting eye drop technology using an amorphous synthetic silica composite was developed to address this. Our study aimed to assess the safety and tolerability of the Silica Eye Drop platform in healthy volunteers over
