[Experiments on the toxicity of intra-ocular administered Gentamycin (author's transl)]
Abstract:
The compatibility with Gentamycin solution used for irrigation of the anterior chamber of the eye was studied in experiments performed on rabbits. The degree of damage was measured by counting the number of the undestroyed cells of the corneal endothelium after perfusion. We compared the number of undestroyed cells after perfusion with 0.25% Gentamycin solution, 0.50% Gentamycin solution and Ringer solution. The result of these experiments showed a clear reduction of the endothelial cells using a 0.50% solution of Gentamycin. On the other hand there was not found any considerable difference between the number of cells using a 0.25% solution of Gentamycin or using Ringer solution. Using both solutions there was only a very slight degree of damage to be observed.
Insights
The 0.25% Gentamycin solution showed minimal corneal endothelial cell damage, similar to Ringer solution. However, the 0.50% Gentamycin solution caused a significant reduction in these vital eye cells.
Area of Science:
- Ophthalmology
- Cell Biology
- Pharmacology
Context:
- Ocular irrigation solutions are crucial in ophthalmic surgery.
- Gentamycin is an antibiotic used for prophylaxis and treatment of ocular infections.
- Assessing the safety of intraocular solutions is critical for preventing ocular surface damage.
Purpose:
- To evaluate the compatibility of Gentamycin solutions with the corneal endothelium.
- To determine the safety of using varying concentrations of Gentamycin for anterior chamber irrigation.
Summary:
- Experiments were conducted on rabbits to assess corneal endothelial cell viability after irrigation with 0.25% Gentamycin, 0.50% Gentamycin, and Ringer solution.
- A significant decrease in corneal endothelial cells was observed with the 0.50% Gentamycin solution.
- No considerable difference in cell count was found between the 0.25% Gentamycin solution and Ringer solution, indicating minimal damage.
Impact:
- Results suggest that 0.25% Gentamycin may be a safer concentration for intraocular irrigation compared to 0.50%.
- This study provides valuable data for ophthalmologists regarding the selection of appropriate antibiotic irrigation solutions.
- Findings contribute to the understanding of drug-induced toxicity on the corneal endothelium, informing clinical practice and future research.
