Drusen – Know the Difference Between Hard and Soft Drusen

January 25th, 2012

Macular drusen are simply small yellow or white deposits of lipid (a fatty compound) and calcium that build up in the Bruch’s membrane of the eye. The Bruch’s Membrane is a layer of tissue underneath the retina.

My husband, who has a strong family history, went for his yearly eye exam this week, and we wanted to know if any of these little, yellow deposits had developed in the past year. Thankfully, not yet.

Well, why is this important to know? And if I have some of these deposits should I be concerned? It may depend on what type you have.

There are two main types:

1) Hard and

2) Soft

Hard Drusen

This type of deposit is the less harmful form. They are characterized by:

round shape
distinct, well defined borders
and are quite small.

They are:

1) Very common with age and are

2) Very often seen in those 40 and older

3) Not an indication of the development of macular degeneration

4) May develop into the soft kind

5) Made up of lipids and calcium

Soft Drusen

This type is considered to be an early indicator of macular degeneration, although some people with this type do not develop macular degeneration.

The soft form are characterized by:

pale yellow
ill-defined borders
larger than the hard form
vary in size and shape.

Soft Deposits:

1) Are more often associated with loss of vision

2) May cause the retinal pigment epithelium (RPE) to separate from the other retinal layers.

If you have a family history of macular degeneration it is especially important to know if you are forming these deposits.

Once they have been detected in your eye exam, it is time to take note and make some changes in your diet and lifestyle.

Former FDA LASIK regulator says FDA “Screwed Up” back it accustomed LASIK – ABC Good Morning America

January 20th, 2012

When it first approved laser devices for LASIK indications in 1995, CDRH screwed up in not applying its own less-than-1% standard for acceptable adverse events reported from clinical studies, former ophthalmic devices division director Morris Waxler told FDA Webview in a teleconference interview 9/3. Waxler said FDA was under enormous industry pressure when it approved the new indication and its standards for the procedure were cobbled together. Primarily, he said, CDRH totally lacked in-house LASIK expertise at the time and incorrectly judged the significance of adverse events, which the divisions own standards said should be less than 1% of all procedures. Actual experience was above 5% in permanent adverse events that the agency listed in the wrong column as so-called second-tier complications such as patient-reported persistent pain, blurred images and night-vision difficulties that were not counted as first-tier adverse events (retinal detachment, lost visual acuity, induction of astigmatism, etc.). I think we screwed up, Waxler said. Nobodys going to admit that. Basically, I think people made some of those judgments incorrectly. We were getting advice from very renowned ophthalmologists — more renowned than anyone we had in the agency. We dropped the ball.

Patient Tom had a aggravation (corneal infection) afterward PRK in his appropriate eye 10 years ago which was adapted by 2 added laser treatments

January 12th, 2012

Pt. Tom had PRK in his right eye over 10 years ago but developed a central corneal infection 3 days after the PRK. Although the infection was controlled, he was left with a central scar in his cornea. The scar was removed with another laser treatment (PTK) but this left him farsighted. Farsighted treatments with the laser were not yet FDA approved so he wore a contact lens for 2 years. After FDA approval for farsighted PRK with the Visx laser(we were involved in that FDA study) we then corrected his eye with a third laser treatment. He did will but over time as he aged he became more farsighted and last week we performed a 4th PRK in that eye to correct his farsighedness. He is now doing well and we expect he will achieve good vision. He had uncomplicated LASIK in his left eye about 8 years ago. His infection was the only serious infection I have ovserved in treating thousands of patients since 1990 and he is one of only a few patients who I have treated 4 times.
