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...
Effect of intravenous mannitol in post vitrectomised eyes
The purpose of the study was to evaluate the effect of intravenous mannitol 20% on intraocular pressure in vitrectomised silicone-oil filled eyes. A prospective analysis of consecutive patients was undertaken with their fellow eyes taken as controls. Thirty-one patients were...
Optical quality difference between monofocal and multifocal intraocular lenses
It is well known that multifocal intraocular lenses (IOLs) can generate more than one focus to restore distance and near vision, but patients may experience adverse optical phenomena such as decreased contrast sensitivity and induced glare or halos. The authors...
Effect of refractive corneal surgery on IOP and glaucoma progression
Accuracy of intraocular pressure (IOP) measurement depends on the biomechanical properties of the cornea, including its thickness central corneal thickness (CCT) and keratometry (K). Fifty-six eyes of 56 patients with primary open angle glaucoma (POAG) who had a history of...Quiz Oct/Nov 2022
History An Afro-Caribbean woman, aged 30, with “scleral tattooing” for cosmetic reasons (subconjunctival dye injection), presented with bilateral upper and lower eyelid oedema for one week, and she also had restricted eye movement and blurry vision in her right eye....Simulation in ophthalmology: a pedagogic viewpoint
The advent of simulation technology has enhanced modern medical training. The first utilisation of simulation was in 1929 where Edward Link used this concept to develop a mechanical flight simulator [1]. Industries such as aviation, nuclear power and the military...
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...
Relationship between nocturnal intraocular pressure elevation and diurnal intraocular pressure level in NTG patients
This group studies Korean normo-tension glaucoma (NTG) patients over a 24-hour period to assess if there was a relationship between nocturnal intraocular pressure (IOP) and diurnal IOP. They have previously suggested differences in diurnal IOP may have varying mechanisms of...
Prognostication for uveal melanoma
The authors highlight the importance of using all available data in the prognostication of uveal melanoma (UM). Over recent years a number of molecular tests have emerged to allow clinicians to predict metastatic potential of UM. However, concordance between techniques...
Oculoplastic Surgery (Third Edition)
This is a single author textbook in its third edition that reflects the author’s extensive experience and also their detailed, methodical and organised approach to oculoplastic, orbital and lacrimal surgery. It is a widely known and popular textbook, not only...
