Weekly Glance for October 8th

What's new in optometry, week by week.

YOUR RUNDOWN

A couple of odd case reports made the news this week.

First up, persistent red-tinted vision with Viagra use.
A 31-year-old man drank an unknown amount (but suspected to be more than the recommended dosage) of liquid sildenafil citrate (aka Viagra) that he purchased online. He presented to the ER two days after taking the medication with complaints of persistent red-tinted vision. He was found to have cone photoreceptor damage with ERG and a bullseye appearance in the macula on OCT. Typically, visual symptoms associated with sildenafil citrate tend to be transient and resolve over 24 hours but here is a case where the symptoms have persisted for six months and may even become permanent. This case report was published in Retinal Cases and Brief Reports and reported on by CNN and USA Today. (via

Next, a chiropractic adjustment leads to preretinal hemes.
A woman presented with unilateral preretinal hemorrhages immediately following neck manipulation with her chiropractor. Given that this patient was healthy and no other etiology was found for the hemorrhages, it was presumed that the neck manipulation itself induced vitreo-retinal traction that likely led to preretinal hemorrhages. The other theory is that it induced a PVD. These hemorrhages were self-limiting and resolved over two months. (via)

 
 

We won something.

That's how many NOVA students and OD's feel. The deal NOVA made with National Vision to rename the college is off. In case you missed it, the backstory was in the last Glance.
 

Edit: There was an error in the Glance last week on when to send a patient to the ER with an elevated blood pressure. The correction is rather than focus on just one number, the article actually suggests looking at the symptomatology, medical history and fundus exam. 
 

WHAT YOUR PATIENT MIGHT ASK YOU

Can what I eat make my AMD worse?

There is growing evidence suggesting it can.
A collaboration of researchers in Europe found that patients that adhere to a Mediterranean diet reduced their risk of late-stage AMD by 41%. 

What is a Mediterranean diet?
It's a
 diet rich in plant-based foods. Think fruits, vegetables, nuts, seeds, legumes, fish, seafood, and olive oil. It emphasizes limited red meat consumption, processed foods, and added sugar.

What are the study details?
The authors studied the data of over 4,000 participants in two different studies (the Rotterdam study and the Alienor study). In these studies, food questionnaires were given to patients every 5 years over a 21 year period for the Rotterdam study and every 2 years over a 4 year period for the Alienor study.

What did they find?
The researchers found that those who closely followed the diet were 41 percent less likely to develop AMD compared with those who did not follow the diet.

What if I just add fish to my diet - is that enough?
No. The authors did not find that the reduced risk was tied to just one food, rather it was the entire pattern of eating a nutrient rich diet that did it.

SOCIAL MEDIA ROUNDUP

The need for protective glasses even as a spectator.

The sad story of a woman that lost sight in her right eye after being struck with a golf ball at the Ryder Cup.
 

OD win.

Congratulations to this Georgia OD who made a life-saving diagnosis.
 

We are all collectively grossed out by this guy.

This basketball player cleaned his contact lens in his mouth on national TV. He will forever be ridiculed by the optometric community. Best of luck with the ulcer that awaits you!
 
Done for today! Have a great Monday!
See you next week!
