Unique case of steroid-induced intraocular pressure spike causing NAION

The literature describes previous cases of nonarteritic anterior ischaemic optic neuropathy (NAION) following rapid rises in intraocular pressure (IOP) leading to reduced optic nerve head perfusion and disruption. This is commonly following ophthalmic procedures, acute glaucoma or steroid eye drops....

The rate of realignment of two toric monofocal intraocular lenses (IOL)

This retrospective study used the American Academy of Ophthalmology Registry data to analyse the need of reoperation for realignment within the first year after cataract surgery with a TECNIS or AcrySof monofocal toric IOL implanted during 2016 and 2017. They...

Effect of caffeine and low intensity endurance exercise on intraocular pressure

This placebo controlled, double blind, balanced crossover study reports in healthy individuals that 30 minutes of cycling caused a maximum of 2.7mmHg lowering of IOP. A caffeine dose of 4mg/kg 30 minutes prior to cycling negated this effect. The conclusion...

Multicentre PCO rates in different brands of monofocal intraocular lenses

This was a longitudinal, retrospective cohort study featuring 47,754 (three years) and 20,763 (five years) eyes with age-related (≥65 year) cataract surgeries between 2010-2013 across seven UK ophthalmology clinics. The three- and five-year incidence of posterior capsular opacification (PCO) and...

Does religious fasting affect intraocular pressure or retinal parameters?

Nearly one billion Muslims fast every year during the month of Ramadan. Due to the difference between the lunar and solar calendars, religious fasting time can range from 11 to 17 hours per day. This prolonged abstinence from food and...

An unusual case of silicone oil in the anterior chamber simulating intraocular implant

Silicone oil internal tamponade has been used for over 50 years, even prior to pars plana vitrectomy [1].Over a course of time silicone oil may migrate to the anterior chamber through the pupil. This may disperse in the form of...

Correlation between peak intraocular pressure following water drinking test and pulsed methylprednisolone therapy

Steroids have long been known to cause increased intraocular pressures (IOP) in susceptible patients. Intravenous methylprednisolone is used to treat many rheumatological conditions and one of the risks is raised intraocular pressure. It would be useful to find patients at...

Optic nerve head perfusion response to reduced blood pressure and increased intraocular pressure

The purpose of this prospective study was to test the hypothesis that blood flow autoregulation in the optic nerve head has less reserve to maintain normal blood flow where there is a blood pressure induced decrease in ocular perfusion pressure...

Outcome of secondary intraocular lens implantation-conventional 23- vs. modified 27-gauge vitrectomy port anchor fixation

This retrospective case study series evaluated the outcome of a secondary intraocular lens (IOL) implantation technique of a Carlevale IOL (Soleko IOL Division, Italy) with either a conventional 23- or a modified 27-gauge (-g) vitrectomy port used as anchor fixation....

Results after 1.4mm biaxial cataract surgery and implantation of a new aspheric intraocular lens

The aim of this study was to analyse the clinical outcome and higher-order aberrations (HOAs) after 1.4mm biaxial micro incision cataract surgery (B-MICS) and implantation of a new aspheric intraocular lens (IOL). A total of 157 eyes of 106 patients...

Closed-chamber haptic re-externalisation for posteriorly displaced sclerotomy and inadequate haptic tuck in glued posterior chamber intraocular lenses

This technique (online video http://jcrsjournal.org) emphasises the importance of both symmetrical and sufficient anterior placement of sclerotomies to externalise an adequate length of the haptics, which in turn provides good centration and stability of the intra-ocular lens (IOL). The authors...

Endothelial keratoplasty (EK) with anterior chamber intraocular lens (ACIOL) versus secondary posterior chamber lens (PCIOL)

This is a retrospective study of 82 eyes (23 ACIOL, 59 PCIOL) with a history of either pseudophakic (PBK) or aphakic (ABK) bullous keratopathy, who had descemet stripping automated endothelial keratoplasty (DSAEK) with retained or secondary ACIOL, or DSAEK with...
