A case series of acute visual loss following excessive alcohol and / or drug use
This study presents three cases of so called Saturday night retinopathy, an acute visual loss following intravenous drug abuse and stupor, leading to continuous pressure on the orbit while asleep. All three cases presented with acute vision loss and had...
Influence of overall intraocular lens diameter on rotational stability
It has been shown that approximately one in three patients undergoing cataract surgery have >1.0D corneal astigmatism and managing this during surgery is important to achieve good refractive outcomes. One of the widely used ways of reducing preoperative astigmatism during...
Collamer lenses for accommodative ET
Posterior chamber phakic IOL implantation was used to treat patients with accommodative esotropia (ET) with the goal of eliminating hyperopia and producing orthophoria. Three patients (six eyes) aged 18-22 years had an average follow-up of 17 months ±6.24. The mean...
Conjunctival inflammation in glaucoma patients
Numerous studies have demonstrated that topical medications and preservatives used for the management of glaucoma can induce significant histopathologic and inflammatory changes in the ocular surface. This study describes an increased expression of major histocompatibility complex class II antigen HLA-DR,...
Full thickness macular hole after YAG PI
The authors report a case of macular hole post YAG peripheral iridotomy (PI) of a patient with pre-existing vitreomacular adhesion. Although a relatively safe procedure, some anterior segment complications are well documented such as corneal endothelium damage, rise in IOP,...
Vital dyes in ophthalmology
This comprehensive review gives an excellent summary of the uses and properties of the different dyes available to aid better visualisation and diagnoses in ophthalmology. The authors clearly display the pharmacological properties, molecular details, osmolarity and indications in clinical ophthalmology...
Congenital aniridia clinical features
In this study the authors investigated the various ocular and systemic features associated with congenital aniridia in Indian eyes (262 eyes of 131 patients). The median age at time of first hospital visit was eight years (one day to 73...
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...
Pterygium ocular surface temperature
This prospective study investigated the ocular surface temperature in patients with pterygia compared to those with dry and healthy eyes respectively. Previous studies have shown that patients with dry eyes show a significant decrease in ocular surface temperature on sustained...
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...
Risk calculation variability over time in OHT
In this study the authors aimed to assess the variability of the well documented risk model from the Ocular Hypertension Treatment Study (OHTS) that identified higher intraocular pressure (IOP), older age, lower central corneal thickness (CCT), greater vertical cup-to-disc ratio...
