Three low-viscosity perfluorocarbon liquids provided an intraoperative tool during vitrectomy to manage giant retinal tears. These clear fluids have a high specific gravity (1.8 to 1.9) and are immiscible with water. In six eyes, the giant tear was less than 180 degrees; in 11 eyes, it was 180 degrees or greater. In all eyes, the tear was unfolded and the retina was flattened while the patient was supine. The perfluorocarbon liquid was aspirated and replaced by air-perfluorocarbon gas mixtures (16 eyes) or silicone oil (one eye) at the end of the operation. The retina was reattached in 16 eyes (94%), with a minimum follow-up period of 6 months. In five eyes (29%), the retina was reattached without scleral buckling. Residual droplets of perfluorocarbon liquid were observed in four patients. These new materials complement present surgical techniques for managing giant retinal tears.

Background: Differentiating arteritic anterior ischaemic optic neuropathy (A-AION) due to giant cell arteritis (GCA) from non-arteritic anterior ischaemic optic neuropathy (NA-AION) may pose a diagnostic challenge. Our study aimed to assess the use of standard orbital MRI in distinguishing ocular manifestations of GCA from NA-AION.
Methods: This study included 25 consecutive patients (11 GCA, 14 NA-AION) who underwent contrast-enhanced orbital MRIs within 3 months of symptom onset.

To investigate the use of short-term postoperative endotamponade with perfluorocarbon liquids (PFCLs) for the treatment of giant retinal tear-associated rhegmatogenous retinal detachment (RRD). This retrospective study evaluated patients who had 2-stage surgery, which entailed pars plana vitrectomy (PPV) completed in 2 consecutive surgeries spaced 5 days apart, during which a short-term tamponade with PFCL was used (Group 1), and patients who had conventional single-stage PPV with long-term silicone oil (SO) tamponade (Group 2). The study comprised 74 eyes of 68 patients, 52 in Group 1 and 22 in Group 2.

Giant cell arteritis (GCA) is a vasculitis characterised by arterial inflammation, with permanent vision loss being a feared complication. The association between GCA and viral infections is well-known, but there is limited data regarding its relationship to COVID-19. A man in his 80s with a recent history of COVID-19 developed sudden vision loss, persistent headaches and jaw claudication.

Purpose: To report the technique and long-term outcomes of patients with giant retinal tear associated retinal detachment (GRT-RD) treated with pneumatic retinopexy (PnR).
Methods: Retrospective cohort study. All patients presenting with GRT-RD with tears in the superior ten-clock hours who underwent primary PnR were included in this study.
