Symmetry is expected in nature. Asymmetry is not expected. Symmetry is expected in virtually everything we see. Our brains have been conditioned to expect symmetry and when we view asymmetry it confounds our thought process. When evaluating the eye and associated adnexa the clinician must understand the analysis of symmetry as well as the underlying pathophysiology (tissue alteration) of the disease. Recognition of asymmetry is a tremendous asset in the practice of medical eye care and this discussion will address this principle.

Introduction Of Sepia Tones To The Current View Options In Medical Imaging
It has been established that the human eye sees color best but it is influenced by many factors. Issues such as chromatic aberration of the eye certainly impact on human perception as does brightness fatigue from the high-energy end of the spectrum…blue and ultraviolet light. Also blue light is inherently scattered more and because of chromatic aberration focuses in front of the retina creating a “blue defocus often estimated at the Snellen equivalent of 20/40”. The following from http://www.telescope-optics.net/eye_chromatism.htm illustrates both the proposed longitudinal and lateral eye chromatism.
Eye Care’s Opportunity in Health Care Reform
This paper was originally published in November 2010 and several times since, under different titles and for focused audiences. Why another re-write? As you would expect, time has passed and events needed to be updated. The more important reason, however, is you. This time around, the audience is you, eye care providers from all corners of the profession. There is another important change as well. Formerly, my colleague and I wrote from a position of vendor bias. Coming now from Eye Care Advice, this reiteration of the message comes without vendor bias. I remain indebted to my colleague, James E. Grue, O.D. for his unparalleled insight into health care reform. Together, we wish you every success as you continue to dig deep to understand the changes you must make in order to thrive in the new era of value-driven health care we call “reform”.
From Eye Care EHRs to Direct Messaging, Care Teams and Bundled Payments
The word “inclusion” just shouts out its counterpart, does it not? Exclusion!! That’s not a pretty word; no warm fuzzy feelings there. Sadly for eye care providers, and especially independent practitioner ECPs, exclusion from the new healthcare game is a threat to be taken rather seriously.
This paper is about inclusion not exclusion. It’s about helping you understand the new rules of the new game in healthcare. It’s about helping you score winning goals in the game of health care reform.
A White Paper for Optometry
Health care reform is upon us like a storm in the night. Portability & interoperability, transparency & value-driven health care, clinical outcomes & evidence-based medicine. What are these concepts and why should optometrists pay attention?
