I am excited to lead the September Optometry and Vision Science (OVS) with a superb publication of the Prentice Medal Lecture by Larry Thibos, PhD, FAAO. You will be reminded not only of Thibos’ wonderful contributions as a researcher and teacher but also how Charles Prentice himself influences modern optics. Accompanying the article is a video of the actual lecture and slides Thibos presented in October 2012, along with a version for the hearing impaired. You will delight in his masterful presentation and explanation of the relationship between “Prentice Rule” and the wonders of Thibos’ “modern optics” applied to wavefront refraction. OVS is proud of this landmark presentation.
In 2014, Thibos and his colleagues will be presenting an entire issue of OVS dedicated to wavefront optics and its clinical application. You can expect a Call for Papers in the October issue of OVS. And while on the subject of Feature issues in OVS, I trust you enjoyed last month’s August 2013 Feature issue that showcased the impressive strides and impact that advances in the “Measurement of the Patient’s Perspective” is having. In November 2013, we follow up with a second 2013 OVS Feature issue; this one entirely dedicated to Myopia research. A continuing education course next month in Seattle is based on this theme issue (“OVS Presents: Myopia”). In 2014, in addition to the “Wavefront Refraction and Correction”, we also bring a Feature Issue on advances in research, both clinical and basic, in age-related macular degeneration (AMD) with internationally profiled Guest Editors; the Call for Papers for that issue can be found in this issue of OVS. The Call for Papers is for a theme issue dedicated to basic and clinical advances in AMD. Our AMD team of Guest Editors come from around the globe, each a recognized expert in some aspect of AMD—its underlying mechanisms, treatments, and consequences. So once again, OVS readers can look forward to two full Feature issues in 2014; each on a very current and important topic of huge clinical interest.
The current September issue has the usual wide range of interesting publications you have come to expect in OVS. As a follow on paper to the Prentice Medal publication, we have authors finding that although spherical aberration varied with sphere power as predicted by optical theory, the spherical aberration levels varied between lens designs and can change when placed on the eye. Other authors’ research revealed that Rembrandt was probably not strabismic but rather painted with that artistic style. Separately, we learn that the risk of microbial keratitis with overnight corneal reshaping contact lenses appears similar to that with other overnight modalities, and that a new metric known as “cumulative comfort” to assess ocular comfort over the day was highest for one of the study contact lenses the authors tested.
Other authors studied the relative contributions of hypoxia and mechanical force to changes in corneal sensitivity during contact lens wear; they provide indirect evidence that mechanical force from contact lenses may be the key player. We learn that discontinuation of daily-wear silicone hydrogel contact lenses over a 2-year period was about 30% in Chinese children aged 7 to 14 years—most within the first month and rarely as a result of any adverse effect that caused vision loss. Beyond contact lenses, we have publications on lack of relationship between symptom level and clinical grade of signs in convergence insufficiency, a case for more focused vision screening programs, and the changing aberrations of the aging eye that results in a proposal for an age-adjusted aspherical intraocular lens. Finally, OVS presents four Case Reports that highlight a novel approach to ocular metastasis, a cautionary alert on latanoprost, and conclusions on attempts to identify parameters in the successful use of scleral lenses to treat dry eyes.
