Creating aerosolized droplets in phacoemulsification
A wetlab was set up using porcine eyes, an artificial anterior chamber maintainer, and an Alcon Infiniti phacoemulsification system (Fort Worth, TX; Fig. A). Colouring dye was placed in the irrigation fluid for easy identification of droplets on a white paper surface surrounding the eye. During simulated phacoemulsification, droplet/aerosol production occurred when the irrigation ports were in the incision, but not when they were entirely within the anterior chamber. A similar study, using cadaveric eyes and a 2.2 mm phacoemulsification sleeve, also found that no droplet/aerosol was produced when instruments were held entirely within the anterior chamber.Paracentral acute middle maculopathy following high-intensity interval training
High-intensity interval training (HIIT) is a cardiovascular exercise strategy that combines short bursts of intense anaerobic exercise with quick recovery periods. There are significant cardiovascular, metabolic, and mental health benefits associated with HIIT.1 Furthermore, this exercise regimen is correlated with better macular and optic nerve head capillary perfusion, microvascular remodelling, and decreased size of the foveal avascular zone in the long-term.1,2Referral outcomes from a vision screening program for school-aged children
To assess ocular diagnoses and follow-up patterns of children referred for a comprehensive eye examination after a school-based vision screening program.Opacification of hydrophilic acrylic intraocular lens following vitreoretinal surgery: a clinicopathological report
Intraocular lens (IOL) opacification is a rare complication following cataract surgery. IOL opacification has been reported in various types of IOL, including polymethylmethacrylate, hydrophobic acrylic, and hydrophilic acrylic lenses. This increasingly recognized clinical entity could result in a range of symptoms, such as reduced or foggy vision, glare, and halos around bright light. Not uncommonly, IOL exchange is necessitated to improve visual function. Over the past decade, there is a growing literature on IOL opacification following intracameral gas during lamellar corneal transplantation.Exudative retinal detachment secondary to hypertensive crisis related to membranous nephropathy
Membranous nephropathy is the most common cause of nephrotic syndrome in Caucasian adults, though rare, with an estimated annual worldwide incidence of 1.2 per 100 000 persons.1 In membranous nephropathy, autoimmune complexes deposit on and thicken the glomerular basement membrane.2 Of the patients with membranous nephropathy, 12% proceeded to renal failure in a longitudinal study.3 Patients with end-stage renal disease on dialysis are at significantly increased risk of exudative retinal detachments.
