What is the coffee ring effect?
I was once characterized as an “information parasite” by a colleague. I must admit that I do troll the Internet, particularly Pub Med, for new, intriguing information especially when its related to one of my two favorite ocular phenomenon that are pseudoexfoliation syndrome and the lid margin.
Dr. Kathy Mastrota explains antibiotic resistance
Optometry Times Editorial Advisory Board member Katherine M. Mastrota, MS, OD, FAAO explains the mechanism of antibiotic resistance and its importance to eyecare practitioners.
How bacteria load creates a biofilm
First acquired during birth from the mother and rapidly thereafter from the surrounding environment, bacteria colonize our conjunctiva and lacrimal systems. It is estimated that more than 200 species of bacteria commonly inhabit the human conjunctival mucosa.
Why you’re missing the dry eye right in front of you
Why you’re missing the dry eye right in front of you
A common barrier to many practitioners is the concern that their practice does not have the patient foundation to make investment in the services economically profitable. I assure you that OSD management will profit the patient in many ways that includes clearer, more comfortable vision, enhancing their productivity and overall wellbeing.
The connection between dry eye and eyelashes
While there are a myriad of associated concerns due to ocular surface inflammation, a few eyelash-related complications of note are trichiasis, acquired distachiasis, local madarosis, and poliosis. Each of these is in some way connected to dry eye.
Goblet cells’ role in tear stability and ocular surface health
Recently, I was stopped in my tracks when I overheard a colleague comment that she was unaware that topically administered cyclosporine (Restasis, Allergan) increases goblet cell density.
Diagnosing and treating lagophthalmos
Since I read Dr. Robert Latkany’s study on nocturnal lagophthalmos in 2006,1 I am perpetually on the lookout for it, especially in the patients who present with dry eye symptoms. Sometimes it’s easy to spot lagophthalmos—sometimes, if you ask your patient about lid closure, they will report to you that they know about their incomplete lid closure, mostly when they sleep.
How hygiene products affect ocular surface and lids
It’s sort of funny—one of my childhood recollections is a discussion with my mother (the PhD in organic chemistry) regarding the virtues of Phisohex (hexaclorrphene, Septisol), a facial cleaner. “Phisohex is pH balanced,” she said, “so it is better for your skin.” At the time, the pH comment wasn’t important to me. What was important was that my mother said I should use it, and therefore the characteristic 1970s green bottle of Phisohex was standard at each sink in our home.
The evolution of tear substitutes
In an ongoing effort to ameliorate the discomfort and blurred vision that stems from dry eye, tear substitutes have undergone numerous improvements to enhance their efficacy and safety to the ocular surface.
The pros and cons of clear lens exchange
More and more well-informed individuals are requesting lens extraction for refractive purposes even though their natural lenses are clear.
