We investigated how a combination of citicoline and coenzyme Q10 (CoQ10) might impact retinal cell health in a mouse model of ocular hypertension (OHT). Using four groups of mice, including those receiving the combination treatment and a control group, we aimed to understand if these substances could protect against the loss of retinal ganglion cells, which is a major concern in glaucoma.
The treatment was started 15 days prior to inducing ocular hypertension with a laser and continued until we examined the mice about a week later. Our findings were promising: the combination of citicoline and CoQ10 led to a temporary reduction in eye pressure shortly after treatment. Furthermore, it significantly prevented the death of specific retinal cells that are vital for vision.
While we were encouraged by these results, especially regarding cell protection, it's important to note that there were no significant impacts on neurons in the visual pathway areas we studied, like the dLGN. Overall, our research suggests that this combination might offer neuroprotective benefits in specific aspects of ocular hypertension, paving the way for further exploration into treatments that go beyond only lowering eye pressure.
