Will "close work" (e.g., computer at work, reading, etc) be impactful to peripheral lattice retinal degeneration? Or only for myopia progression?

Will "close work" (e.g., computer at work, reading, etc) be impactful to peripheral lattice retinal degeneration?  Or only for myopia progression?

Not likely: There are some animal studies that suggest that intense near work in children could enhance myopia. I don't believe that mechanism is still at play by age 41. There should be no impact on lattice degeneration from computer work or reading. Lattice degeneration per se does not progress. What changes in the eye is the state of the vitreous gel and its relationship to the lattice. ...Read more

Can my vision change from watching television or looking at a computer monitor over time?

Can my vision change from watching television or looking at a computer monitor over time?

Yes: If you are constantly looking at a fixed near distance - like a computer your eye muscles may undergo spasm and you may develop induced nearsightedness. Thats why every 20 minutes of close work look at least 20 feet away for 20 seconds. My 20/20/20 rule. :-). ...Read more

Tics? If all the : Studies were normal, remember that 11% of children with ASD have tics. The latest studies show that kids with adhd who develop tics on the stimulants methylphenidate (concerta) ; amphetamines usually have an underlying tic disorder, so the meds unmask tics rather than induce them. Compulsions? Maybe, but usually not myoclonic. Adding Intuniv for adhd may reduce them, if they are complex tics. ...Read more
