In this video we discuss how to improve the visual outcome of patients suffering from higher order aberrations with pupil dilation.
One of the most common complaints we see in our practices is that of blurry vision. often time, absence of ocular disease, this complaint can be treated with an accurate sphero-cylindrical refraction. but at times, there may be other factors, such as higher order aberrations, we now even have technologies that utilize point spread function but we know that the eyes’ optical
System is dynamic. as the pupil dilates in low light levels that expose certain portions of the eye’s optics this is most commonly seen in patients who have had refractive surgery and those who may have been fit with orthokeratology. others may simply have higher order aberrations naturally in their visual system is there a way to control pupil dilation in the evening?
These receptors are located on the pre-synaptic nerve terminal, which controls the dilator muscle. it causes a negative feedback and inhibits release of norepinephrine. because they tend to have the same level of efficacy realize that this is a non-fda approved use for this medication and it should be discussed as such with the patient before use. understand that higher
Order aberrations with pupil dilation keeping these things in mind will help improve our patients’ visual outcome, we hope that this has been clinically insightful.
