Anyway, you still need to work at having good glucose control to prevent other complications such as kidney disease and neuropathy.People with myopia have longer eyeballs than normal and their retinas are stretched very thin. This makes them vulnerable to retinal detachment which can cause blindness if not treated urgently. Some studies suggest that weight-lifting temporarily spikes the pressure within the eye and therefore increases the risk of retinal detachment. However, a blow to the head is riskier than weight-training so it's more important to avoid contact sports. And bungee-jumping.There is some evidence that the increase in eye pressure is greater when people hold their breath whilst lifting weights so the advice often given is to exhale when doing the active part of the movement and inhale when returning the weight to the starting position. This is thought to reduce the spike in eye pressure. Other activities that increase eye pressure are doing exercises with the head below heart height, such as decline bench presses and playing wind instruments like the trumpet.Although people usually say that the most effective way to build muscle it to use weights that are so heavy that the lifter can't manage more than 5-7 repetitions, it is still possible to build muscle (albeit not quite as effectively) by choosing a much lower weight that can be lifted a maximum of 10-14 repetitions. It's likely that there would be less straining with a lower weight and presumably less spiking of eye pressure. It would be worth discussing this with your ophthalmologist.I presume your doctor warned you of the symptoms of retinal detachment - sudden increase in flashers and floaters and/or a dark "curtain" appearing in the vision - and that it requires an immediate trip to eye casualty.This website might be useful:- <a href="http://www.mind.org.uk/information-support/types-of-mental-health-problems/self-esteem/#.V1hlsfkrLIV" target="_blank">http://www.mind.org.uk/information-support/types-of-mental-health-problems/self-esteem/#.V1hlsfkrLIV</a></blockquote>
