    Special Issue on Optical Coherence Tomography in Clinical and Experimental Optometry

    Recently my colleagues Bang Bui, Laura Downie and I put together a special issue for the journal Clinical and Experimental Optometry which was devoted entirely to the topic of optical coherence tomography (OCT).  This amazing imaging technology – which has only really been in clinical practice for the last decade – has revolutionized the way eye care practitioners detect and manage ocular disease.

     New laser treatment helps to reduce the rate of progression of age related macular degeneration (AMD)

     

    Age related macular degeneration (AMD) is the leading cause of irreversible vision loss in industrialized nations and costs the Australian economy in excess of $2.5 billion per year.  The recent development of the nanosecond laser (2RT, Ellex, Pty Ltd) offers great promise as a treatment that may reduce progression of the disease.

    Tattoos can lead to serious eye problems

    Over the past 50 years there have been at least 15 cases of people diagnosed with tattoo-associated uveitis cited in the medical literature.  Uveitis is a general term describing a wide range of inflammatory diseases that produce swelling and redness within the eye, and ultimately destroys ocular tissue.  The term ‘uveitis’ is used because the diseases often affect a part of the eye called the uvea.

    Customised spectacles using 3-D printing technology

    An amazing paper published recently in Clinical and Experimental Optometry by Dr Onder Ayyildiz describes how customised spectacles were designed and manufactured in Turkey for a five-year-old girl with Goldenhar syndrome, which is a rare congenital condition characterised by incomplete development of the ear, nose, soft palate (the soft tissue constituting the back of the roof of the mouth), lip and mandible (jawbone).

    Recent study shows intraocular lenses not the best treatment option for aphakic babies

    About four years ago I published a blog discussing the relative merits of contact lenses or intraocular lenses for unilateral aphakic babies.  This blog was based on a paper in the Journal of the American Medical Association (JAMA) Ophthalmology which compared the visual outcomes of unilateral aphakic babies optically corrected with contact lenses versus intraocular lenses (IOLs) following unilateral cataract surgery during early infancy.  The study also looked at the efficacy and safety of primary IOL implantation for infantile unilateral aphakia.

    Southern Regional Congress in Melbourne: What I learnt

    In late May, Andrew, Jillian and I attended the Southern Regional Congress (SRC) in Melbourne.  This is the biggest optometric conference in Australia and it is held each year in Melbourne.  This year there were over 850 delegates and – as in previous years – they were treated to some excellent lectures from both local and overseas speakers.  The conference has a strong clinical aspect with many presentations outlining what is considered best practice for the consulting room, however there were also some very good talks which provided delegates with all the latest developments in ophthalmic research.

    Update on cataracts

    May 7, 2018

    Update on cataracts

    Cataracts are a clouding or opacification of the lens inside the eye.  They are generally a result of ageing and long-term exposure to ultraviolet light.  Cataracts may also be caused by trauma to the eye and in rare cases they can be present at birth.  Note that cataracts simply represent a change in or alteration to the lens material – they are not a growth.

    Children and soft contact lenses

    A couple of months ago, my friend and colleague Mark Bullimore published an excellent paper in Optometry and Vision Science in which he critically analysed how safe it was to fit children with soft contact lenses.  Since about the turn of the century there has been less reluctance shown to fit children with contact lenses.

    Multifocal sunglasses

    We are now approaching the warmer time of the year, and – as we all know –   overexposure to UV radiation can cause eye damage, such as swelling of the cornea and the conjunctiva (the ‘white’ of your eye), cataract development and other kinds of problems including pterygium (tissue growth which can encroach on your cornea) and skin cancer around the eyes.

    Our specialist colleagues

    A little while back, one of our corneal transplant patients unfortunately suffered a rupture to their corneal graft due to an accidental poke in the eye from his two year old boy.  Naturally this occurred on a Sunday night.  Our patient was immediately taken to the Royal Victorian Eye and Ear Hospital (RVEEH) where the ophthalmologist on duty advised him that the corneal graft would need to be resutured.

    Age-related macular degeneration

    In late May – May 21 to May 27 – there will be Macular Degeneration Awareness Week which is organized by the Macular Disease Foundation Australia (who do a tremendous job in promoting awareness and educating the public about this serious group of eye diseases).  Hence, it seems only appropriate that I write about this important topic and for this I have called on the services of a guest blogger, namely my wife Professor Erica Fletcher.

    Rigid contact lenses – what’s in a name?

    Rigid contact lenses are available in many forms.  The classification of rigid lenses is usually based on differences in total diameter, although the terminology can vary.  I favour the rigid lens nomenclature whereby corneal lenses have a diameter of 7.0 to 12.0 mm, corneal-scleral lenses have a diameter of 12.0 to 15.0 mm, mini-scleral lenses have a diameter of 15.0 to 18.0 mm and scleral lenses have a diameter of 18.0 to 25.0 mm.

    BCLA - Digital eye strain

    Last month I attended the British Contact Lens Association (BCLA) Asia conference which was held in Hong Kong (in conjunction with the Hong Kong Cornea and Contact Lens Society).  It was an excellent meeting with over 200 delegates from all over the world in attendance and various topics were covered including myopia control, orthokeratology, scleral lenses, dry eye and paediatric contact lens fitting.  One of the best and most interesting seminars at the conference was a presentation given by Peter Kollbaum from the USA on the topic of ‘digital eye strain’.

    Daily disposables – the way of the future

    Disposable soft contact lenses were launched onto the Australian contact lens market in 1989.  Interestingly, for a few years before the introduction of disposable lenses several companies had operated frequent replacement schemes, with the interval between lens replacements generally being three or six months.  These frequent replacement programs were not that successful and it was only with the introduction of disposable lenses – and the subsequent shorter interval between lens replacements – that the concept of ‘frequent lens replacement’ was truly embraced by contact lens patients.

    Hydrogen Peroxide – the Forgotten Cleaning System

    Hydrogen peroxide was introduced as a contact lens maintenance system in the mid 1980s.  At this time, it was seen as a major breakthrough in contact lens cleaning and disinfection, as previously patients had been required to use heat disinfection (which usually led to signification contact lens degradation and deposition) or chemical systems that incorporated preservatives such as thiomersal or chlorhexidine (which often led to adverse reactions from the eyes).

    New registry for corneal collagen cross-linking

    Our experience over the last 10 years with the corneal collagen cross-linking treatment (CXL) of keratoconus shows that this procedure is both safe and effective in halting the progression of the keratoconus.  We also know that the earlier this procedure is offered, the more likely it is to retard keratoconus progression.

    The ‘patching’ you do without a patch!

    Amblyopia (or ‘lazy eye’) is a common visual disorder that affects about 4% of people.  The most common causes are strabismus (where the child has a large squint or ‘turned eye’) and anisometropia (where there is a large difference in the refractive error between the two eyes).

    Presbyopia is a condition where the eye gradually loses the ability to focus at a normal reading distance.  It is usually first noticed between the ages of 40 and 50 years when people find that they can no longer focus comfortably on objects closer than at arm’s length.  Presbyopia is not a disease and it affects everyone.  Presbyopia is usually corrected by reading glasses (which will make near objects clear but distant objects blurry) or multifocal glasses (which incorporate progressive lenses that provide clear vision at both distance and near).

    An issue we face at this practice is non-compliance in contact lens wear. All contact lens wearing patients exhibit some degree of non-compliance with regard to contact lens wear and maintenance, even though most patients consider themselves to be complying with guidelines for lens wear and care that have been outlined to them by their contact lens specialist.
