Effect of laser wavelength on delivering effective burns through opaque lens using pattern scan laser

Panretinal photocoagulation (PRP) has been used in the treatment of various retinal disorders for many decades. Conventional single-spot lasers take quite some time to do with significantly higher pain, anxiety and photophobia when compared to the pattern scan laser (PSL)....

Progression of myopic maculopathy after treatment

The authors report on a retrospective study carried out to evaluate long-term progression of myopic maculopathy and functional outcome in eyes treated for myopic choroidal neovascularisation (CNV) and in eyes without CNV. Fifty-four myopic eyes of 30 patients were included...

Visual fields and OCT in hydroxychloroquine retinopathy

It has been recommended that patients on hydroxychloroquine be monitored regularly for retinopathy. However, there has not been an agreement as to the best screening test for hydroxychloroquine toxicity, which may include visual fields (VF), fundus autofluorescence, spectral domain optical...

Blinking and driving

Spontaneous blinking is dependent on cognitive processes and is regulated by a central pacemaker that is highly sensitive to the attention demands and cognitive workload of the visual task in hand. There is evidence of a variability in the frequency...

Secondary iris-claw anterior chamber lens implantation in patients with aphakia without capsular support

This retrospective, non-randomised, non-comparative, interventional study including 128 eyes of 124 patients that presented with aphakia with no capsular support. All patients consecutively underwent Artisan iris-claw intraocular lense (IOL) implantation between 1997 and 2010. The inclusion criteria were: aphakic without...

Differences of the anterior segment parameters in children with Down syndrome

This cross-sectional study was designed in order to demonstrate the differences in anterior segment parameters in children with trisomy 21. This is important as it may impact on surgical planning when undertaking procedures in the anterior segment such as corneal...

Outcomes of corneal collagen crosslinking (CXL) in pseudophakic bullous keratopathy (PBK)

This was a retrospective non-comparative, interventional case series of 50 eyes in 50 patients with symptomatic PBK who underwent CXL (epithelium-off). Central corneal thickness (CCT), pain score, best corrected visual acuity (BCVA), and corneal transparency were recorded at baseline; at...

Topography based keratoconus progression after corneal collagen cross-linking

Case 1 describes a 35-year-old man with progressive keratoconus (PK). His best corrected visual acuity (BCVA) was right 20/80 (-5.25/-7.75 x 85) and left 20/20 (+4.75/-5.00 x 90). His Ks were right 36.32/48.02 D and 41.15/46.41 D. Right central cornea...

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...

Allergic conjunctivitis evaluation by thermography

Thermography is a non-invasive imaging technique, which uses infrared radiation reflected from an object to estimate the temperature of the object. This paper evaluates the use of thermography to assess allergic conjunctivitis objectively, by using an instrument called ocular surface...

Effect of single intravitreal injection of bevacizumab on contrast sensitivity in patients with central retinal vein occlusion

Central retinal vein occlusion is the second most common retinal vascular disorder after diabetic retinopathy. There are many studies reporting the efficacy of intravitreal anti-VEGF injections for macular oedema secondary to retinal vein occlusions. This paper looks at the contrast...

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...
