Head-mounted display impact

This study investigated the clinical effects of the head-mounted display on the normal eye to obtain reliable safety data in adolescents. The study included 60 volunteers aged on average 14.7 ±1.3 years (13-18) of which 59% were female. Mean best...

An alternative to povidone-iodine for intravitreal injections?

While povidone-iodine (5% aqueous) preparations have historically been considered the most effective antimicrobial prophylaxis for ophthalmic procedures and have been adopted as routine for intravitreal injections, post-procedure pain is a commonly recognized adverse event of IVI and has typically been...

Cyanoacrylate vs. fibrin glue

This study compared the safety and efficacy of fibrin and cyanoacrylate glue for refixating the recessed muscle to the sclera in patients undergoing strabismus surgery. The fibrin group (a) included 21 eyes of 15 patients; mean age of 11.6 ±7.49...

Allergic conjunctivitis evaluation by thermography

Thermography is a non-invasive imaging technique, which uses infrared radiation reflected from an object to estimate the temperature of the object. This paper evaluates the use of thermography to assess allergic conjunctivitis objectively, by using an instrument called ocular surface...

Effects of topical anaesthetic on intraocular pressure

This prospective interventional study assessed the effects of repeated intraocular pressure (IOP) using Goldmann applanation tonometry and applanation resonance tonometry in six volunteers. Previous literature supports IOP reduction using repeated applanation tonometry. Repeated IOP measures were taken alternately on 12...

Effects of blood donation on the physiology of the eye

Hypovolaemia is a state of decreased blood volume, the reduction of which reduces tissue perfusion which may in turn lead to cellular hypoxia and end-organ damage. In blood donation, 500ml of blood is collected in ten minutes. This equates to...

Smartphone use and its effects on eyes

Longitudinal pilot study on 12 young healthy adults comparing effects of smartphone use over a 60-minute period. Reading conditions and smartphone use was standardised for all participants. Ocular symptoms, tear function and binocular vision were assessed before and after each...

Randomised controlled trial for large-angle exotropia surgery

The purpose of this study was to investigate single eye, single setting surgical options to correct 80–90PD of exotropia with two options of muscle transplant and suture hang-back recession. There was retention of anatomical limits of 6mm resection for medial...

Re-evaluation of virtual reality visual field testing

This study evaluated an updated testing algorithm to determine its dynamic range, and to assess if this produced a suitable central hill of vision, and to evaluate test-retest reproducibility in healthy children. This was a prospective study of children with...
