Vitamin A treatment improves blurred vision
Case of persistent corneal epithelial damage after cataract surgery leading to diagnosis of vitamin A deficiency.
Significant relevance to vision treatments
We investigated a case of persistent blurred vision following cataract surgery, leading to the discovery of vitamin A deficiency in a 74-year-old man. Using advanced tests like full-field electroretinograms and optical coherence tomography, we noted significant retinal changes and low vitamin A levels.

After administering vitamin A supplements for three months, we saw remarkable improvement in his vision and retinal health. This highlights the importance of diagnosing vitamin A deficiency, especially in patients showing persistent vision problems post-surgery.

Case study on vitamin A recovery
Corneal perforation due to vitamin A deficiency in a patient with short bowel syndrome.
Significant case on vision health
We examined a case involving a 55-year-old woman who experienced blurred vision due to a severe corneal condition linked to vitamin A deficiency.

After her previous bowel surgery, she suffered from malabsorption which led to this deficiency.

Despite initial treatments, her condition worsened until vitamin A deficiency was diagnosed.

Following intramuscular vitamin A treatment, she notably recovered her vision and overall health.

Vitamin A improves retinal function
Retinal structure in vitamin A deficiency as explored with multimodal imaging.
Significant structural imaging study
Our exploration focused on how vitamin A deficiency relates to blurred vision in a 63-year-old patient suffering from nyctalopia and severe rod dysfunction. Using various imaging techniques, we found that this individual's retinal abnormalities primarily affected the photoreceptor layer.

Notably, even after receiving vitamin A supplementation, his symptoms showed significant improvement, although the retinal lesions did not change. This suggests that while vitamin A treatment can help restore visual function, it may not reverse existing retinal damage related to deficiency.

Significant vision improvement
Excellent! My vision has improved. After taking this vitamin for one month, I noticed that I began to see better. Previously, I had to squint, but one day, I realised I no longer had to. The dryness in my hands and eyes has lessened. I wholeheartedly recommend it.

Vitamin A is more effective
[Effects of different eye protection methods during head and neck surgery under general anesthesia].
High relevance to ocular surgery safety.
We evaluated the effectiveness of vitamin A eye gel as a protective measure for patients during head and neck surgery under general anesthesia. Our study involved 120 patients who were randomly assigned either vitamin A eye gel or erythromycin eye ointment, both paired with 3M transparent tape for eye protection.

Upon examining the outcomes, we found that vitamin A offered significant advantages, specifically in reducing corneal staining and discomfort symptoms like blurred vision compared to erythromycin. Thus, vitamin A appears to be a superior choice for preventing ocular complications during surgery.

VApal shows efficacy for blurred vision
Efficacy and safety of retinol palmitate ophthalmic solution in the treatment of dry eye: a Japanese Phase II clinical trial.
Strong relevance for dry eye treatment.
We explored the effectiveness of retinol palmitate (VApal) ophthalmic solution for treating dry eye in a clinical trial involving 66 patients. Participants were split into two groups; one received VApal, while the other received a placebo.

Over four weeks, we tracked various measures, including improvements in blurred vision. Notably, the VApal group saw significant improvement in blurred vision and other subjective symptoms compared to the placebo.

The study confirmed that VApal is both safe and effective for dry eye treatment, presenting a viable option for those suffering from this condition.

Improved distance vision
My vision has significantly improved! Starting with low eyesight, I was amazed to find my vision enhanced after taking various supplements. Now I can see far distances quite clearly. I'm intrigued by its potential effects on my long-standing allergy issues.
