& Visual training

With Dr. Pierre Elmurr

Benefits In Box

We hope the first quarter of 2013 is providing you with new opportunities to grow professionally with each of your happy patients, now soft contact lenses wearers, now that the holidays are over and you have come back to your academic and work regular activities, the follow up and monitoring of the practitioner are very important to assure wellness and comfort to users during the year.

In the previous issue of NEWS we talked about the importance of strengthening communication with the needs of the potential contact lenses wearer, deepening a little bit more in anamnesis, asking for their free time, outdoor, health and sports, formal and informal activities, such as going to the gym, aerobics, cardiopulmonary activities, and less frequent activities such as riding a bike, going swimming, walking, etc. Now we would like to talk about the importance of specializing in addressing specifically some of them, aiming for taking them to a higher development level and performance as they daily practice such activities. We would like to achieve this by means of visual training, specially training those whose goal is to become elite athletes in the sporting activity.

For this reason, Dr. Pierre Elmurr, optometrist and orthorpist known by his work with high performance, participates in the central article and the interview “Face to Face. He gives us excellent opinions about his job and shows us what we can learn in this practice of visual training with high performance athletes.

Visual Training and Sports Skills

Nelson L. Merchán B. Professional Issues Manager for Central and South America Johnson & Johnson Vision Care

Welcome to this new issue of NEWS The Vision Care InstituteTM Bogota, in which we continue deploying the sports and contact lenses category, from a new perspective, taking into account high performance athletes with whom we could address a new proposal of complementary training that will benefit their competitive development.

The practitioner should not forget their professional integral and professional essence in taking care and improving vision and visual comfort, leaving aside or omitting the assessment results of the visual functions and the status of the other systems pertaining the visual system that together offer wellness to the patient and commit them in their free and correct development within the environment. I specifically refer to the refractive status, motor status, physiological status and sensorial status that together set the base for the person’s complete diagnose of the visual and eye general status, taking into account that their vision should be used at their maximum performance and the highest efficiency.

When we specifically refer to high performance athletes or elite, we talk about those athletes who are actually committed to their physical and mental training to achieve better results in competitions aiming for excellence and, why not, triumph in their respective disciplines. It is in that scenario that the practitioner’s role along with the athlete’s trainer’s role become important to improve the eye-hand, eye-foot reactions, action-reaction, peripheral awareness among other visual skills that can be trained with a specific execution plan that may have clear purposes and goals. There is no general training plan or pattern that may be useful for everyone, each athlete and objective have their own training plan and their own improvement and evolution times.

Many technology devices have been designed for those high level trainings, but sometimes practitioners forget that many of them are based on visual physiological principles and optimization of pertaining devices in visual functioning. Adaptation and convergence exercises, blended reserves, visual fields, saccades in far and near, among others, are details of a training that aims to improve sports skills.

Sport Vision Trainer™ Studies Executive Summary

The publication of data for reliability studies would considerably enhance comparison of the reliability of testing and equipment (Hopkins, 2000). Consequently practitioners can be assured that any improvement in performance is due to interventions introduced and eliminate any familiarisation effect of the SVT™ as a factor. Currently there are no studies that assess the test-retest reliability of the SVT™. Therefore the aim of the present study is to determine the most appropriate duration and frequency.

1

An assessment of a four week familiarisation strategy for the Sport Vision Trainer™ Method: 64 undergraduate students (age 20±4.4yr) gave written informed consent and the study was approved by the local ethics committee prior to testing. Vision health questionnaires were completed to assess suitability for the study. Participants subsequently completed four sessions of six trials at the same time of day to avoid any effects of circadian variations (Atkinson & Reilly, 1996).Trials were carried out on four consecutive weeks using the 32 sensor pad SVT™. A CEM DT-1300 Lux Light Meter was used to set ambient light at 420lux. Participants stood in front of a panel of 32 lights and hit a series of 20 lights which randomly illuminated. The means of the last four measurement trials were displayed at the end of the last test.

1 Results:

The limits of agreement (Loa) analysis shown in Fig 1 and 2 show that absolute reliability is increased from trial 1-trial 2 to trial 3- trial 4. The Loa indicate that in 95% of cases, error decreased between trials from ±1.11 (95% CI, -1.36-2.98 secs) to ±0.74 (95% CI, -1.04-1.86 secs). This is further highlighted by a Pearson’s r value of 0.62 to 0.87 (P>0.05), and a Coefficient of Variation (CV) error decrease from 7.3 % to 4.9% respectively. There was no evidence to suggest that heteroscedasticity is present.

Conclusion: The present study found that the SVT™ to be a reliable measurement of eye-hand coordination providing four familiarisation trials have taken place. Minimal measurement error during the collection of interval-and-ratio-type data is critically important for assessment of performance (Atkinson & Nevill, 1998). Practically, some amount of biological error is always present with continuous measurements.

Therefore reliability could be considered as the amount of measurement error that has been deemed satisfactory for the successful practical use of a measurement device. In order for future research on the validity of the SVT™ to be carried out it is important that the values indicated from repeated measurements are sufficiently meaningful.

In turn the development of a reliable training aid will provide athletes and practitioners an effective tool for improving sports performance through improving performance.

An assessment of a 30 minute familiarisation strategy for the Sport Vision Trainer (SVT™) Method: 60 undergraduate students (age 20±2.4yr) gave written informed consent and the study was approved by the local ethics committee prior to testing. Vision health questionnaires were completed to assess suitability for the study. Participants subsequently completed four sessions 2 minutes apart on the same day using the 32 sensor pad SVT™. A CEM DT-1300 Lux Light Meter was used to set ambient light at 420lux. Sessions lasted approximately 30 minutes depending on participants speed. Participants stood in front of a panel of 32 lights and hit a series of 20 lights which randomly illuminated. The means of the last four measurement trials were displayed at the end of the last test.

2 Results:

The limits of agreement (Loa) analysis show that absolute reliability is increased from trial 1-trial 2 to trial 3- trial 4. The Loa indicate that in 95% of cases, error decreased between trials from ±0.93 (95% CI, -1.13-2.51 secs) to ±0.69 (95% CI, -1.08-1.62 secs). This is further highlighted by a Pearson’s r value of 0.82 to 0.88 (P>0.05), and a Coefficient of Variation (CV) error decrease from 6.2 % to 4.8% respectively. There was no evidence to suggest that heteroscedasticity is present.

1. ¿How important is the participation of a health visual and ocular care professional, as a part of the support health team, of the high performance sports teams?

For the past 18 years, every time that I have tested or screened a team, I have found athletes that wear contact lens and for example need help with comfort or management of dry eyes.

I have also diagnosed numerous eye problems that needed medical attention. You can offer many services to a sports team including: A. Vision screening at training grounds or comprehensive eye testing in your office B. Provide advice and supply good optical filters and sunglasses.

C. Vision training to enhance visual and visual-motor performance The above services allow you to be part of a multi-disciplinary approach to the sports science and sports medicine practitioners that manage athletes.

2. ¿ How to apply the knowledge in vision and sports in the daily conventional examination of visual health?

Always ask your patient what hobbies or sport they participate in. Many patients who wear glasses only may be interested in daily disposable contact lens for weekend sport.

The views expressed in the articles reflect only the view of the authors and do not necessarily reflect the position and policies of The Vision Care InstituteTM.

4. ¿What is the educational role of the visual professional, CL fitter, in face to the expectations of sports performance, in the level of beginner athletes or non constant practitioners?

The age of the athlete is the important factor here. For example If you have an 8 year child who is +8.00DS and needs to wear his glasses to play football them you have 2 options. Offer sports prescription goggles or teach the parents to insert daily contact lens for their child for training and game day. It’s not just about vision training to enhance athletic performance you need to think about the basic needs of the athlete relative to their age, sport and level of expertise.

5. Taking in account clinical factors of the visual field and binocular vision, Do you recommend, per vision and comfort, the use of disposable frequent replacement soft contact lenses, as an integral alternative of correction in high performance athletes?

It’s really an individual athlete’s choice. I educate the athlete about all the possible options and we decide together. Many of my elite athletes travel frequently so daily disposable are best suited for them. I recommend to many of my athletes the Acuvue TruEye daily lens as it a silicone hydrogel material and offers excellent UV protection.

With Dr. Pierre Elmurr

Dr Elmurr is an Australian optometrist and orthoptist, who has worked as researcher and scientist in the sports optometric area, and traveled to Bogota at the beginning of this year, and gave some speeches about sports and vision, and spoke about topics such as the role of the professional in the current vision over the elite sports performance, with arguments of better involvement of the strategies development to sports coaches.

Another example many outdoor athlete’s would have ptyergium’s so discussing the use of good optical filters including polarised sunglasses is a good way to manage athletes at all level and provide a higher level of care which can generate extra income via selling sunglasses for medical reasons in this case to protect the athlete from UV exposure.

Sport is the biggest business in the world and a great topic of conversation with your patients, so understanding sports vision than offering a product or service available in your clinic will generate extra income.

3. ¿Why it is important to the professional CL fitter, having the knowledge of sports visual health?

All the usual complaints such as dry eye, itchy eyes, and comfort issues towards the end of the day will be experienced by athletes you need to understand their sport and its visual requirements to give them better advice.

Elite athletes

In this section, our invitee professional is Dr Pierre Elmurr, who has been realized different studies of evaluation, training and visual rehabilitation in high performance athletes and shown the opportunity of the CL fitters, when they have tried motriz development, sports practices and auto esteem, of theirs wearers fitted with this kind of correction, and give them important plus values to their lifestyle.

In behalf of my partners I thank the staff of “The Vision Care Institute, Bogota” for the effort you make to provide us with high quality training. I think the development of the topics in this 5 th phase had a clinical focus, which will be very useful to improve our private practice. “The Vision Care Institute, Bogota” in these last few years in Latin America has improved the quality of contact lenses fittings with his contribution because it has provided practitioners with clinical tools and has specially helped us to understand the management of our offices aiming for PROFESSIONAL SUCCESS.

Allan Mora Vargas Optometrist Costa Rica

I would like to share my gratitude for inviting me for the first time to one of your trainings at The Vision Care Institute de Bogota, Colombia. The 5th Phase with a sporting and research focus has been very interesting, and I identify myself with it because I like research and innovation for my patients. It was a great academic and professional experience, where I had the opportunity to share with high-level Colombian practitioners, along with my dear national colleagues who were as well invited. We learnt and lot and there is a lot to implement.

Thank you for this very useful business tool called The Vision Care Institute.
