Everything You Need to Know About Oral Glaucoma Medications

Posted by Amanda Dexter on Oct 7, 2019 9:09:48 AM
 
 

Systemic medications for intraocular pressure (IOP) control are typically reserved for cases in which a significant temporary drop in IOP is required that cannot be achieved by any other means.
 
Oral preparations are most commonly used in cases of acute angle-closure glaucoma or surrounding intraocular surgery, in which substantial pressure spikes may arise.
 
Because these medications are not as often prescribed as our work-horse topical medications, we’ve put together a quick review of everything you need to know about oral glaucoma drugs in case you are in a situation where these are needed.

Posted by Amanda Dexter on Sep 23, 2019 2:10:09 PM

If you are anything like me, when I hear of a patient on their way into the office complaining of sudden onset of double vision, I get a little worried! I was never good at remembering all of the cranial nerve palsies, signs, symptoms, diagnoses, and causes.

6 Mimickers of a 6th Cranial Nerve Palsy

Posted by Amanda Dexter on Sep 16, 2019 12:20:56 PM

The abducens nerve (6th cranial nerve) controls a single extraocular muscle; the lateral rectus. The lateral rectus is primarily responsible for abducting the eye. A palsy of the abducens nerve is the most common ocular motor paralysis; the affected eye turns inward toward the nose and is unable to abduct properly.

The deviation is constant and is typically greater at distance fixation than at near. The esotropia is also more noticeable when the patient is looking toward the affected side. Diagnosis of a 6th cranial nerve palsy may seem pretty straight forward when piecing together the patient’s history and examination findings; however, you should keep in mind that there are several conditions that may imitate isolated lateral rectus weakness.

We will review these 6 mimickers of a 6th nerve palsy for your review!

Everything You Need to Know About Fourth Cranial Nerve Palsy

Posted by Amanda Dexter on Sep 10, 2019 7:03:16 PM

The fourth cranial nerve (trochlear nerve) controls the actions of a single extraocular muscle; the superior oblique. The trochlear nerve has several unique aspects; it is the smallest nerve in terms of the number of axons it contains, it has the longest course through the skull than any other cranial nerve, it is the only cranial nerve that exits through the dorsal aspect of the brainstem, and it innervates the superior oblique muscle on the contralateral side from its nucleus.

Diseases or injuries of the fourth cranial nerve can lead to paralysis or weakness of the superior oblique muscle which will cause certain signs and symptoms that you will see upon examination.

With that being said, there are a few conditions that you don’t want to miss as the first physician to see the patient; an acquired third nerve palsy is one of them.

What Optometry Students Should (and Should Not) Wear to Clinic

Posted by Amanda Dexter on Jul 15, 2019 9:00:00 AM

Most optometry schools will provide incoming students with some general dress code guidelines for clinic, and in some cases, standards for even just attending classes. The most important reason for a dress code is to ensure that students are presenting themselves in a professional manner as they are a not only a representation of the school, but of the profession of optometry as well.

Most optometry students are not used to dressing in this manner on a daily basis, so it may take a little time and experimenting with different clothing and shoes options to find that perfect balance of professionalism and comfort. We’ve come up with several tips to help get your clinic wardrobe started!
