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...

Management of restrictive diplopia after ptergium surgery

This single centre retrospective case series included 15 patients with restrictive diplopia after ptergium excision. The mean time from surgery to diplopia was six months and all patients had a moderate limitation of abduction in the operated eye causing an...

Ocular manifestation of Marfan Syndrome

This repeated cross-sectional study collected data in 2003-2004 and 2014-2015 to investigate changes in ocular features in Marfan syndrome (MFS) fulfilling the Ghent-2 criteria. Ghent-2 is a set of criteria by which MFS are identified and includes aortic root aneurysm...

Biometry measure after cycloplegia

The authors investigated optical biometry in an Indian paediatric population on normal and cataract paediatric eyes and studied the effect of cycloplegia on different parameters measured in these eyes. This was a prospective study of 76 eyes aged five to...

Van Herick Plus

This a consecutive cross-sectional study of 95 phakic patients over the age of 40-years-old. By applying a short, vertical slit beam, the inferior angle at the scleral-limbal junction at 6 o’clock position was evaluated, photographed and assessed by a ratio...

Colour Doppler imaging before and after orbital decompression in thyroid eye disease

In this prospective, uncontrolled study euthyroid patients with moderate to severe inactive thyroid eye disease underwent colour Doppler imaging before and after orbital decompression. Patients with dysthyroid optic neuropathy, corneal breakdown, systemic disease (diabetes, cerebrovascular accident, cardiovascular and peripheral vascular...
