New concepts in diagnosis and treatment
In the past decade, several significant advancements have been made in the arena of glaucoma diagnosis. Spectral domain optical coherence tomography (SD-OCT), newer algorithms in trend analysis of visual field studies, and combined visually evoked potential (VEP) and pattern electroretinography (ERG) studies have been the hallmarks of such recent advancements.
Helping patients better understand glaucoma
When I was a resident at the SUNY College of Optometry, I was asked a to conduct a few patient question and answer sessions regarding glaucoma. The sessions consisted of me sitting with a small group of patients, family members, or whoever wanted to know more about glaucoma.
Using medications in pregnant glaucoma patients
Most of the medications, both new and old, we prescribe for glaucoma are quite safe—especially if we educate our patients to occlude their puncta.
How oral and dental hygiene plays a role in glaucoma
In the past couple of years, there has been discussion regarding dental and oral health—specifically the oral biomicrome—as possibly having a relationship to glaucoma.
Effects of concurrent use of topical, oral beta blockers
Recently, I received a progress note from a glaucoma surgeon concerning a patient whom he and I share. The patient is a 58-year-old African-American female with a longstanding history of primary open-angle glaucoma.
Standards of care in treating glaucoma
As technology and glaucoma care evolves, so must our treatment guidelines
How alcohol consumption correlates with glaucoma
How alcohol consumption correlates with glaucoma
With the advent of electronic health records, it is now easier than ever to keep up with what medications a patient is actually taking, and (especially in the arena of glaucoma) the several classes of medications, such as steroids, beta blockers, and antihistamines, that can influence how patients’ eyes behave. With this in mind, I had a patient come in the other day with an interesting question regarding her intraocular pressure (IOP).
Why retinal vasculature could aid glaucoma diagnosis
Congenital anomalies, angle closure, and juvenile open-angle glaucoma aside, it can be generally agreed upon that glaucoma tends to be a disease of relatively older persons. This rings especially true in the arena of normal-tension glaucoma in which intraocular pressure (IOP) may play less of a causative role compared to vascular and hemodynamic dysfunction.
How patients perceive their glaucoma matters
At the completion of the examination, I was getting ready to walk her up to the front when she stopped me and said she had a very serious question. We both sat down, and she asked me how long she had before she went blind because her mother went blind from glaucoma before seeking ophthalmic care.
Drance hemorrhages and quarterly optic disc evaluation
Not very long ago, a 55-year-old African-American female presented with complaints of redness in her right eye for one week’s duration with mild discomfort. Medical history was significant for arterial hypertension, which was reportedly controlled with an oral beta blocker.
