Hypothesis

Can nerve growth factor levels be detected in aqueous humor from human eyes?

Conclusion

The study found that nerve growth factor levels in human aqueous samples were undetectable.

Supporting Evidence

  • NGF levels were below undetectable levels in aqueous humor from eyes with POAG and controls.
  • Less than 10% of samples had detectable NGF levels and these were considered outliers.
  • The mean age of subjects with POAG was 74.2 years and 69 years for controls.

Takeaway

The researchers tried to find nerve growth factor in eye fluid from patients, but they couldn't find any.

Methodology

Aqueous humor samples were collected from 32 patients and analyzed using an ELISA immunoassay.

Potential Biases

Outliers in the data may skew results, and sample collection variables could affect outcomes.

Limitations

The study faced challenges in collecting sufficient sample volume and detecting nerve growth factor levels.

Participant Demographics

18 patients with primary open angle glaucoma and 14 control patients undergoing cataract surgery.
