Effect of methylcobalamin in accommodative dysfunction of eye by visual load

Area of Science:

• Ophthalmology
• Neuroscience
• Biochemistry

Background:

• Prolonged visual work can lead to accommodative dysfunction.
• Methylcobalamin, a form of vitamin B12, plays a role in neurological function.
• Assessing the impact of methylcobalamin on visual accommodation is crucial for eye health.

Purpose of the Study:

• To investigate the effect of methylcobalamin on accommodative function after experimentally induced visual work.
• To determine if methylcobalamin can mitigate the deterioration of accommodation.

Main Methods:

• Small fluctuations of accommodation were measured to assess accommodative function.
• Subjects underwent induced experimental visual work.
• Comparison between methylcobalamin, placebo, and non-administered groups.

Main Results:

• Deterioration in accommodative function was less pronounced in the methylcobalamin group.
• A significant decline in accommodative function was observed in the non-administered and placebo groups (P < 0.05).
• The non-administered group showed a greater decline than the placebo group.

Conclusions:

• Methylcobalamin demonstrates a beneficial effect on accommodative function compromised by visual work.
• While a placebo effect exists, methylcobalamin provides objective improvements.
• This suggests methylcobalamin as a potential aid for managing visual fatigue and accommodative issues.
