A metabolic aspect of high myopia
Annals of Ophthalmology
|September 1, 1985
Summary
High myopia and retinal detachment are linked to altered zinc and copper metabolism. Elevated serum zinc and copper levels were observed in patients with retinal detachment, suggesting a connection to retinal pigment epithelium function.
Area of Science:
- Ophthalmology
- Trace Element Metabolism
- Retinal Physiology
Background:
- Abnormal zinc and copper metabolism is implicated in retinal pigment epithelium disorders.
- High myopia is associated with significant anatomical changes in the retinal pigment epithelium.
Purpose of the Study:
- To investigate zinc and copper levels in blood and urine of high myopic patients.
- To compare these levels between different ethnic groups and those with primary retinal detachment.
- To explore the relationship between serum and subretinal fluid metal concentrations.
Main Methods:
- Blood samples analyzed for zinc and copper concentrations.
- Urine samples analyzed for copper concentrations.
- Patient groups included high myopic Black and White individuals, and White individuals with primary retinal detachment.
Main Results:
- White myopic patients often exhibited high serum zinc and low serum copper.
- High myopic patients with primary retinal detachment showed statistically significant elevations in both serum zinc and copper.
- An inverse relationship was observed between serum and subretinal fluid copper/zinc ratios.
Conclusions:
- Altered zinc and copper metabolism may play a role in high myopia and primary retinal detachment.
- Findings suggest a potential link between these metal imbalances and retinal pigment epithelium dysfunction.
- Further research is warranted to elucidate the precise mechanisms and clinical implications.
