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.

Visual performance in monosodium glutamate-treated rats.

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%); ... There was no obvious correlation between ophthalmoscopic appearance of the retina and visual outcome; ... The approach to atrophic ARMD presented here warrants informal practitioner replication and formal randomized prospective clinical case-control evaluation."

Our animal model duplicated the serologic changes (low folic acid, high formate) as well as these histopathologic changes. ... CONCLUSION: Mitochondria can be impaired either genetically (as in Leber's) or through acquired insults (such as nutritional or toxic factors). Either may challenge energy production in all cells of the body. ..."
Eye disorder linked to ADHD in children
NEW YORK, Apr 14 (Reuters Health) -- An eye disorder appears to be
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
``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
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
``More study needs to be completed to confirm the connection and to
answer these questions,''
Granet also noted that convergence insufficiency responds to eye
exercises that can be done at
