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 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...
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...
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...
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...
Infections related to strabismus surgery
This review considers the range of infections occurring with strabismus surgery. Extraocular infections include conjunctiva, sub Tenon’s abscess and orbital cellulitis. Intraocular infection includes endophthalmitis. Prevention of infection and risk factors includes the issue of scleral penetration and use of...
Perception of depth in 3-D media
The aim of this study was to evaluate the relationship between clinical measures of stereoacuity and the perception of depth in 3-D entertainment media. Fifty-seven subjects aged 16-62 years with stereopsis and no strabismus were assessed. Monocular blur was used...
IOP and reversibility of RPE detachment
The authors describe how three patients with retinal pigment epithelium (RPE) detachment showed a reduction or disappearance of an RPE detachment immediately following prone dark room test (PDRT). The authors performed spectralis OCT on 140 angle closure subjects before and...
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...
Pentacam vs. IOL Master keratometry measurement in IOL power calculations
The IOL Master measures only the anterior corneal curvature and estimates the total corneal power by assuming a fixed relationship between the anterior and posterior corneal surface. The Pentacam measures both the anterior and posterior corneal surface and therefore calculates...
High myopes with POAG and IOP fluctuations
The authors describe a prospective study of 80 eyes of Chinese patients with primary open-angle glaucoma (POAG) on prostaglandin analogues to investigate if those who also have high myopia exhibit greater short-term intraocular pressure (IOP) fluctuations at resting conditions over...
