Acid phosphatase in eyes with pseudoexfoliation
American Journal of Ophthalmology
|April 1, 1980
Summary
Pseudoexfoliation in the eye is linked to higher acid phosphatase activity. This enzyme was detected in pseudoexfoliative materials using histochemistry and was elevated in aqueous humor samples.
Area of Science:
- Ophthalmology
- Biochemistry
- Histochemistry
Background:
- Pseudoexfoliation is an ocular condition affecting the anterior segment.
- Acid phosphatase is an enzyme with various biological roles.
Purpose of the Study:
- To investigate acid phosphatase activity in the anterior segment of eyes with pseudoexfoliation.
- To compare enzyme activity between pseudoexfoliation and non-pseudoexfoliation cataractous eyes.
Main Methods:
- Histochemical staining (light and electron microscopy) to detect enzyme activity.
- Biochemical assays to quantify enzyme levels in aqueous humor.
Main Results:
- Histochemistry showed acid phosphatase activity within pseudoexfoliative materials.
- Biochemical analysis revealed significantly higher acid phosphatase levels in pseudoexfoliation eyes compared to controls.
Conclusions:
- Acid phosphatase is present and active in pseudoexfoliative deposits.
- Elevated acid phosphatase in aqueous humor may be a biomarker for pseudoexfoliation syndrome.
