Blind Cricket

Steve Palmer, Ricky Segura and Matt Cameron (on debut), all with Retinitis Pigmentosa (RP), were the standout performers for Australia in Adelaide during the Australia vs England Lord's Taverners International Blind Cricket Series earlier this year. Unfortunately Australia lost the ODI series 4-1 but split the T20 series 1-1.  England ODI captain Matt Dean (RP with Ushers) dominated the series and was awarded the Vision Australia 'man of the series' and an iPad Pro.

Blind Cricket Australia Chairman and Australian fast bowler Ray Moxly (who has ocular albinism) said, "Blind Cricket is a sport for people who are legally blind at all levels but those who just qualify as being legally blind tend to have the greatest impact on a match.  Australia needs to find more well sighted (but legally blind) athletes if it wants to remain competitive at the international level."  A blind cricket 11 is comprised of 4 partially sighted (B3) players, 3 poor partially sighted (B2) players and 4 totally blind (B1) players.  Batsmen hitting 4's and 6's is a common occurrence, there are plenty of classic catches taken and the best bowlers deliver the ball at 100kph!!
 

Queensland Blind Cricket is currently looking for new players as it heads into a Summer of Cricket.  The Queensland Squad for the upcoming National Championships will be selected in the next two months and the Australian team will head to India in January to take part in the T20 Blind Cricket World Cup.

There is an indoor cricket version of Blind Cricket too.  This game is called Vision Impaired Indoor Cricket, it is suitable for players with a reasonable level of vision and is played every Monday night at Toombul, Brisbane.

If you have diabetes eating fish may save your sight

Posted in 'General' on August 20, 2016 by Stuart Macfarlane
 
Regular intake of long-chain omega-3 polyunsaturated fatty acids obtained from oily fish was associated with a reduced risk of sight-threatening diabetic retinopathy in middle-aged and older patients with type 2 diabetes, according to a study conducted in Spain.

The study's finding that consumption of at least 500 mg/d of dietary long-chain omega-3 polyunsaturated fatty acids (LC3PUFAs) decreased the risk of diabetic retinopathy (DR) in patients with diabetes corroborates experimental models and the current theory of DR pathogenesis, according to the report.

The prospective investigation included 3,482 patients with a mean age of 67 years diagnosed with type 2 diabetes who had participated in the PREDIMED study, a randomized clinical trial that tested Mediterranean diets supplemented with extra virgin olive oil or nuts vs. a control diet for primary cardiovascular prevention.

Among the 3,482 patients, 2,611 (75%) consumed the recommended amount of at least 500 mg/d of LC3PUFA, which could be achieved with two servings of oily fish per week.

Bleach in my eye! First Aid for Chemical Burns.

Posted in 'General' on August 27, 2016 by Stuart Macfarlane

Bleach, oven cleaner, ammonia, detergents, pool cleaner and vinegar: we are all familiar with these useful chemicals for cleaning and use them often. However if any of these chemicals spatter into your eye it is a true ocular emergency that can possibly lead to blindness or visual impairment and requires treatment IMMEDIATELY. 
 

About two-thirds of chemical eye injuries occur in industries where dangerous chemicals are used, and the remainder occur at home mostly from cleaning products. 

Here is a list of chemicals that are harmful to your eyes:
Alkali
-Bleach
-Lye
-Cements
-Plasters
-Airbag powder
-Ammonia
-Solvents
-Potassium hydroxide
-Sodium hydroxide
-Magnesium
-Lime
-Fertilizer
 
Neutral Irritants 
-Mace, pepper spray
-Household detergents
 
Acidic 
-Battery acid (automobile battery)
-Pool cleaner
-Vinegar
-Glass polish (hydrofluoric acid)

Alkali burns are the most dangerous and harmful to the ocular surface as alkalis penetrate the cornea (the clear window in front of the eye) more deeply and rapidly than acids and will cause more severe injuries. 

Symptoms of chemical burns include pain, redness, tearing, blurred vision, difficulty with keeping the eyes open, irritation and swelling of the lids. 

The first and most important treatment for chemical burns is to irrigate and wash the injured eye copiously with water or saline for at least 20-30 minutes. The longer the chemical remains in the eye the more devastating harm it causes. Also it is very important to open the eyes as wide as possible to effectively wash off the chemical. It is often useful to hold the lids with both hands to keep the eye open. 

It would be ideal if irrigation can be performed with an irrigating solution such as Eye Stream or saline, but tap water is also appropriate.  
 

When seeking medical help or calling an ambulance, it is essential to inform the health care practitioner what chemical was splashed in the eye and if in an industrial setting to provide a MSDS: Material Safety Data Sheet. Irrigation must be continued until the ambulance arrives or you arrive at a hospital emergency department. 

The types and duration of treatment depend on severity of the burn, which is graded from Grade 1 to Grade 4. 
Grade 1: Clear cornea, only epithelial damage and no limbal ischemia 
Grade 2: Hazy cornea, iris details visible, less than 1/3 of limbal ischemia
• Grade 3: total loss of corneal epithelium, stromal haze, 1/3-1/2 limbal ischemia
• Grade 4: Opaque cornea, more than ½ limbal ischemia

Overall chemicals must be used and treated with great care and protective goggles used. If chemical spatters into the eye remember two things: IRRIGATE COPIOUSLY and SEEK MEDICAL HELP IMMEDIATELY.
