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...

Cost-effectiveness of femtosecond cataract surgery

Femtosecond laser-assisted cataract surgery has become increasingly popular due to the reported benefits of increasing precision and reproducibility of capsulorrhexis, less power and manipulation required during phacoemulsification, better corneal wound architecture, and the ability to place precise arcuate keratotomy incisions...

Risk factors and untreated POAG

The authors examined 50 untreated open angle glaucoma patients to determine if there was an association between the level of glaucomatous damage and documented risk factors. In this study the authors measured the extent of morphologic and functional glaucomatous damage...

Piggyback toric IOLs in complex cases

This study evaluates the outcome of toric sulcus fixated lenses (MS 614/714 TPB (Human Optics, Germany) in 21 eyes with high astigmatism. The cases included previous penetrating keratoplasty (n=15), post cataract surgery astigmatism (n=3), rotation of in-the-bag toric IOL (n=1),...

Orbital filler for enophthalmos in Parry-Romberg syndrome

This is a retrospective review of three patients with enophthalmos in sighted eyes secondary to Parry-Romberg syndrome. The patients were all female, aged between 24 and 54. All three patients had 4mm of relative enophthalmos prior to treatment. They each...

Effects of blood donation on the physiology of the eye

Hypovolaemia is a state of decreased blood volume, the reduction of which reduces tissue perfusion which may in turn lead to cellular hypoxia and end-organ damage. In blood donation, 500ml of blood is collected in ten minutes. This equates to...
