    " Oral administration of 50 mg tartrazine to 122 patients with a variety of allergic disorders caused the following reactions: general weakness, heatwaves, palpitations, blurred vision, rhinorrhoea, feeling of suffocation, pruritus and urticaria. There was activation of the fibrinolytic pathway . . ."

    " The purpose of this study was to examine the effect of monosodium glutamate on the visual performance in rats. . . . In conclusion, glutamate treatment was shown to cause dose-dependent deficit in visual performance and this may reflect impairment of visual organs and brain function."

    "...Fourteen male patients ... were placed on an additional portion of 5 ounces sauted spinach 4 to 7 times per week or lutein-based antioxidant (three patients)... Patients demonstrated short-term positive effects in visual function in one or both eyes with this mild therapeutic approach: Amsler grid (87%); Snellen Acuity (71%); Contrast sensitivity (92%); SKILL (65%); Glare recovery (69%); and Activities of Daily Vision Subscale (60%); ...

CONCLUSION: Mitochondria can be impaired either genetically (as in Leber's) or through acquired insults (such as nutritional or toxic factors).

    Eye disorder linked to ADHD in children

    NEW YORK, Apr 14 (Reuters Health) -- An eye disorder appears to be linked to attention-deficit/hyperactivity disorder (ADHD) in children, according to University of California, San Diego researchers.

    The eye problem, called convergence insufficiency, is a physical problem of the eye that makes it difficult to keep both eyes focused on a near target. The disorder affects less than 5% of children -- but the research team found that it is three times more common in children with ADHD than in other children.

    ``This is the first report on the potential connection of these two disorders,'' Dr. David B. Granet said this week during the American Academy of Pediatric Ophthalmology and Strabismus meeting in San Diego.

    Granet and colleagues reviewed the records of 266 children identified as having an inability to keep both eyes focused on a close target. The investigators found that 26 children (9.8%) also had a diagnosis of ADHD. ``Twenty of these patients were on medication for ADHD when diagnosed with convergence insufficiency,'' Granet told Reuters Health.

    When the researchers reviewed their institution's records of 1,700 children diagnosed with ADHD, they discovered that about 176 also had eye exams, Granet said. ``Of these, almost 16% or 28 children also had convergence insufficiency,'' he added.

    This analysis shows that ``children with ADHD had three times the incidence of convergence insufficiency than what was expected in children walking in off the street,'' Granet said.

    Convergence insufficiency ``makes it more difficult to concentrate on reading, which is also one of the ways doctors diagnose ADHD,'' Granet commented.

    ``Convergence insufficiency may not be well known outside the field of eye care specialists,'' Granet told Reuters Health. ``We don't know if children are being misdiagnosed with ADHD when they truly have convergence insufficiency or vice versa,'' he said. ``We also don't know if one causes the other or if medications used for ADHD cause convergence insufficiency,'' he added.

    ``More study needs to be completed to confirm the connection and to answer these questions,'' Granet said.

    Granet also noted that convergence insufficiency responds to eye exercises that can be done at home.
