This past weekend I went for my regular, every two years eye exam and was told that I have drusen in my right eye. It's not affecting my vision but the doctor couldn't say how long it's been present since it hadn't been noted before. (But then, I'd never had my pupils dialated before. Hated it! Mad)

He talked a little about it and gave me an Amsler grid to check my vision regularly. I looked up info, of course, but what I'd really like is to hear from people who have this condition and how it has or hasn't affected them. The medical info gave me more questions to ask of my doctor but I'm looking for the individual perspective.

Hi Raku, fancy meetin' you here Big Grin

Well, I know you asked for people that have had this...and I don't, but I didn't want you to think that no one was paying attention to your question. I did do some research on Drusen and came up with a few things. (I hate getting my eyes dialted too! Eek) Anyway, I know this isn't really what you wanted, but I hope it helps some anyway. Smile

This site basically gives information about Drusen and also has some graphics to see. It's pretty interesting and can give some of the other readers of this thread some insight.

These are excellent articals on the signs, complications, progression, treatment, prevention and more.

What are drusen?

Retina lines your eyeball the way rubber lines a tennis ball. Drusen are nodules beneath your retina in a layer is called Bruch’s membrane which lies beneath your retina and the adjacent retina pigment epithelium layer.

Drusen may be metabolic waste products from various layers of your retina (retina, retina pigment epithelium and choriocapillaris).

Fat accumulates in Bruch’s membrane with age. This may contribute to drusen.

Drusen occur in two forms:

Hard, small (less than 63um in diameter) drusen do not increase with age and do not predispose to macular degeneration.
Soft, large (more than 63 um in diameter) drusen enlarge and become confluent with age, may predispose to macular degeneration, are more commonly seen in eyes of people with advanced macular degeneration in their other eye.
Risk factors

Family history

UV and visible blue light

Animal studies suggest UV and visible blue light damage retina
No human clinical data establishes cause and effect between UV and visible blue light to macula degeneration, but there may be an association between increased visible light exposure during later years and macula drusen, but that study has not been confirmed by subsequent studies.


Causes or contributing factors

Idiopathic & spontaneous

Embryonic, congenital or developmental

Disorders of your eye

Disorders of your body

Disorders due to agents, toxins or drugs

Drusen can be confused with:

Cuticular drusen

Basal laminar drusen

Dominant drusen in young people

Pattern dystrophy of the Retina Pigment Epithelium

North Carolina fundus dystrophy

Fundus albi punctate dystrophy

Alport’s disease

Ring-17 chromosome retinopathy

Symptoms

Most people with drusen have no symptoms and suffer no complications

Most people who have drusen and suffer complications in one eye suffer no complications in the other eye

Drusen may affect contrast sensitivity

Drusen may affect reading in dim light

Drusen may affect driving at night

Signs

Focal or diffuse deposits in Bruch's membrane

Drusen may be:

Yellow, white, gray, refractile, pink
Small, medium or large
Regular or irregular
Symmetrical or asymmetrical
Complications

Hard, small drusen

none
Soft, large drusen

Retina pigment epithelium atrophy
Choroid neovascularization
Retina detachment serous
Retina detachment hemorrhagic
Aggravating conditions

Soft, large drusen in macula have greater risk of choroid neovascularization

Progression

Drusen enlarge and retina pigment epithelium layer thins.

Drusen become yellow or gray, but can be pink, crystalline, refractile

Drusen vary in size from small to large and irregular

Drusen increase in number and size but can fade and decrease in number

10% of people with soft, large drusen in each eye may develop destruction of retina pigment epithelium after five years

Evaluation

Eye health examination

Amsler grid

Treatment

No demonstrated clinically-effective treatment known.

Treatment under investigation include:

Laser of or around drusen can reduce drusen and improve vision
Choroidal Neovascular Prevention Trial showed argon green treatment reduced drusen but was associated with increased new blood vessel growth under the macula in the other eye three years after treatment.

Mild diode laser treatment reduced drusen without statistically-significant new blood vessel growth under the macula.

Complications of AMD Prevention Trial (CAPT) evaluates mild argon green laser photocoagulation in patients with drusen in both eyes. (www.nei.nih.gov/neitrials)
Prophylactic Treatment of AMD Study (PTAMD) tests mild diode laser treatment of patients with drusen in both eyes and in one eye. (www.irismedical.com)
Laser around macula
Diet


Age Related Eye Disease Study is a randomized, controlled prospective clinical trial that enrolled 4357 participants in four groups: placebo, antioxidants (vitamins C and E plus beta-carotene), zinc, antioxidants plus zinc. Analysis of data shows that high daily doses of vitamin C (500 mg) vitamin E (400 IU) beta carotene (15 mg) and zinc oxide (80 mg) may modestly reduce risk of progression (28% progression in untreated people reduced to 20% progression in treated people) of those who have intermediate-sized drusen, large drusen or non-central geographic atrophy or advanced macular degeneration in one eye.

Rheotherapy is the removal of high molecular weight molecules from your blood plasma, and may be associated with improved vision.
Multicenter Investigation of Rheopheresis for AMD (MIRA-1) is a prospective clinical trial in Phase III

Supplements
Zinc: oral zinc supplement may reduce vision loss in people with drusen or atrophic retina pigment epithelium after two years compared to placebo, but this is not confirmed by a larger study. Dosage, magnitude of effect and complications from zinc are not established.

Antioxidants (Vitamin C, E, carotenoids): while people with elevated blood antioxidant levels are half as likely to develop macula degeneration as those with lower levels, this does not imply cause and effect, nor does it imply that increased antioxidant consumption will reduce or reverse macula degeneration.

Prevention

Near vision card

Amsler grid

Factoids

No difference between men and women

Can develop in young adults and can progress

86% of white Chesapeake Bay watermen have hard drusen

13% of white Chesapeake Bay watermen over 50 years old have soft drusen

Thanks, Puppy. Smile Great amount of info there, some I had seen, some new. I appreciate you looking...Really hoping to find someone who is living with the condition and get the "personal" point of view.

My eye doc gave me a bunch of vitamins to try...I'm still very much in the "wait and see" stage of the condition and wonder if anyone has tried the vitamin approach and if it's made a difference. Smile
