Previous studies have reported cataract surgery post trabeculectomy to be detrimental to IOP control. Conversely, other studies have reported phacoemulsification performed before trabeculectomy as a factor for bleb failure. The objective of this retrospective case control study was to evaluate...
Thinking outside the box – adapting to the COVID-19 lockdown
How can we avoid further delays to follow-up in glaucoma patients? The author asks if there is a socially distanced way to check IOPs in those at high risk of losing vision. Glaucoma is an asymptomatic condition. Loss of the...Unique case of steroid-induced intraocular pressure spike causing NAION

Herpes zoster, Intraocular pressure, Ischemic optic neuropathy, 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....

For this study, the authors analysed the pooled data from three phase2b / 3 multi-centre randomised controlled trials carried out over three years. Included patients had undergone at least one of the following treatments: 1) systemic therapy (corticosteroid / immunosuppressant...
Implantation of intraocular pressure sensor in glaucoma patients
The authors report safety and accuracy of an intraocular intraocular pressure (IOP) sensor placed in the ciliary sulcus during planned cataract surgery. Six patients underwent implantation of the device; a silicone rubber ring-shaped device encapsulating pressure sensitive capacitors and a...Factors influencing the outcome of GT and TBT in PCG
