Weekly Glance for June 18th

What's new in optometry, week by week.


Does having cataract surgery worsen wet AMD?

A new study published in the American Journal of Ophthalmology did a review of 81 eyes with wet AMD that underwent cataract surgery.  

Tell me about the eyes.
All had received at least one intravitreal injection within the 6 months prior to surgery. Twenty three eyes showed fluid on OCT prior to surgery but had received an anti-VEGF injection on average 13 days prior to surgery. They monitored the patients OCT's 4-6 weeks after surgery and 6 months after surgery.

What did they find?
There was a significant improvement in the BCVA after cataract surgery and no significant difference in central thickness on OCT.

The take home:
"Patients with both cataracts and wet AMD may safely undergo cataract surgery. Patients with stable preoperative fluid on OCT should be considered for cataract surgery, as these patients did well postoperatively, with no worsening of their neovascular process."


Let's talk glaucoma implants.

Allergan has been working on a sustained-release glaucoma implant.

What is it?
It's called Bimatoprost SR and it's a biodegradable implant that dispenses bimatoprost (aka Lumigan) for at least 4 months. It's injected into the anterior chamber and is visible in the inferior iridocorneal angle where it slowly dispenses medication and degrades.

How much IOP reduction?
In their Phase 3 trial, it reduced IOP by 30% over 12 weeks which is similar to topical prostaglandins.

When will this be a thing?
Not until next year. Allergan plans to submit a new drug application to the FDA in 2019. (via)



Should I take a blue light eye vitamin?

The eye vitamin aisle is quickly becoming more like the artificial tear aisle.
Bausch + Lomb is adding Ocuvite Blue Light eye vitamins to their already large family of eye vitamin products.

What's in it?
Each capsule contains 25 milligrams of lutein and five milligrams of zeaxanthin isomers, the key eye nutrients that help absorb blue light before it reaches the macula.

Who is it for?
It's marketed to digital device users. (via)



Have you ever wondered if it's possible to impale yourself in the eye with a saucepan? 

It is.

If you're into architecture...

This newly designed "retina house" actually blinks.
Nice work!
Also, my apologies for slacking in the month of June. There wasn't a Glance last week and there won't be one this coming week either because I'm in the process of moving from Milwaukee to Boston. But I'll be back at it July 2nd!

See you then!
