For all the general public.

The Association for Research in Vision and Ophthalmology (ARVO) had arranged 5 days international conference at Hawaii convention center, Honolulu, USA from April 29, 2018. It was an overwhelming knowledge sharing colloquium with around 11,000 basic and clinical researchers from all over the world. The focus of the grand meeting was divided into many ongoing, leading and new aspects of vision researches covering: ocular pathologies & newer treatment options, ophthalmic imaging & diagnostic tools, newer clinical aspects & instrumentation along with adaptive optics & basic researches in vision science.

Prominent researchers in myopia study and MYFUN fellows had well covered myopia research domain targeting prevalence, heritability, possible cause, myopia progression and probable management options. According to investigators, the myopia management options are mainly divided into three aspects: therapeutic management (using medicines), optical management and environmental modification. The therapeutic management claims to slow down the myopia progression by using specific eye drops under routine medical supervision. Optical management is predominantly focused in using specially designed myopia control contact lenses to slow down the myopia progression.

At the same time, some scientists are now putting more stress on environmental modification as studies show a combined effect of genetic and environmental factors on myopia development. Hence, altering daily physical activities or increasing outdoor activity may be a way to fight against myopia mainly during childhood. However, scientists could not achieve a definite myopia management option yet. It is now believed that delaying the onset of myopia may be one of the best strategies by increased outdoor activities in children. This will eventually reduce the risk of permanent vison loss due to ocular diseases related to high myopia.

Despite the more clinical nature of this conference, certain new ideas emerged in the field of myopia research. Such as reading white text on black background may cause less myopia than conventional black text on white. According to another study, optical treatment may not be equally effective throughout the whole day, although they require more evidence. Therefore, it is also important to know, when to apply optical treatments for myopia control. It is always interesting to see where new research ideas leading us to better myopia management.

The next summit we are looking forward for further research update and discussion at the 9th Visual and Physiological Optics meeting (VPO 2018) in Athens, Greece from August 29 to August 31, 2018.

    Great to see remarkable progress in myopia research all around the globe in different frontier.Although progression of myopia is complex in nature but I was just wondering about the effect of different treatment modalities.Which one is most effective to stop maximum myopia progression?.Since last 20 years we have been trying to arrest it by controlling accommodation & peripheral hyperopic defocus therapeutically and optically but most studies shows a minimal reduction within a range of 1-2 D. Is there any role of scleral rigidity and peripheral hyperopic defocous along with genetical connection for it’s progression?

    Hi Avik. Thanks for your comment and interest.
    You are absolutely correct that since a very long time we are trying to understand the process of emmetropization, myopia onset, progression and any possible association with peripheral refraction. The peripheral hyperopic defocus has also been an issue of long ongoing debate; whether its a cause or consequence of myopia progression. And it’s a typical chicken-egg issue. For a long time, we got several published evidence to show peripheral hyperopic defocus may have a role in axial elongation. However, some recent studies reveal peripheral hyperopic defocus is more likely to be a consequence of myopia rather than the trigger. Several attempts are being made from different perspectives to arrest myopia progression as mentioned in the article. Unfortunately, all of them have limited success and we are running behind in the race with myopia progression. Hence, some scientists (Donald Mutti et, al. 2018) are working on delaying the onset of myopia (by environmental modification) to avoid high myopia development and possible associated ocular pathological changes. Scleral rigidity may also have some role in myopia development. However, I come across some recent papers showing no useful association.
    We need to understand that all myopia is not the same. So any one treatment modality may not be useful for all of them. According to Prof. David Atchison in one of his papers, there may be different types of myopia in terms of the retinal region affected: stretching in the periphery, posterior pole elongation and global expansion.
    However, we are optimistic to find a perfect strategy to arrest late onset myopia and its progression in near future.
