Eyes
A. Context
The particular challenges of those with blepharospasm are surveyed here. Some people have this one type of dystonia. When the involuntary muscle spasms and contractions of the muscles around the eye are accompanied by involuntary and sometimes forceful contractions of muscles of the jaw and tongue, those who have meige syndrome diagnosis may also be responding to this survey.
Patients with other forms of dystonia sometimes report occasional eye involvement. Difficulty looking straight ahead can result in seeing objects from a tilted angle or a delay in the adjustment of the eyes to a new head position.
B. Timeline
1887- Horatio Wood, neurologist in Pennsylvania describes dystoniaof the eyes and in the jaw
1900- French neurologist Henry Meige studies a condition in ten patients with jaw oddities and eyelid closure. Meige at first believed patients lacked ‘psychical equilibrium’, and suffered from melancholic temperament and emotional stress but in 1910 found evidence that there was an actual change in the activity of the midbrain in the basal ganglia.
1972 – Neurologist Dr. George Paulson studied jaw and eye dystonia in 3 patients in the US
1980 Dr. Alan Scott, a San Francisco ophthalmologist found that if a patient had eyes looking different directions, strabismus, (crossed eyes), one way to help them was to cut away the muscle that pulled the eye to one side. However this destroyed the muscle and he found that another way to fix the problem was to inject botulinum toxin to temporarily weaken that muscle. He proposed injecting botulinum toxin in the eyelid muscles of people with blepharospasm. This weakened but did not destroy the muscles around the eye.
1989- the US Food and Drug Administration approves use of botulinum toxin Botox BT-A for treatment of eye dystonia
C. What seems useful to study
Clamping shut of eyelids is not difficult to identify but slight delay in opening or closing eyes may be more subtle. Ability to focus the eyes is a separate concern. Vision is affected by fatigue so effects of dystonia may be difficult to isolate since patients with dystonia often report exhaustion and problems sleeping. Vision tends to deteriorate with age so for seniors with dystonia, it may be unclear which changes in vision are due to dystonia and which ones are due to ageing.
Some anti -anxiety medications and anti-depressants can cause blurred vision and those medications are frequently prescribed for those with dystonia.
Many people with dystonia report dizziness. Blurred vision may make a person feel dizzy, or the dizziness may be due to balance problems not related to vision. Many medications have a side effect of dizziness. The study of eye involvement and dystonia therefore is complex and the surveys look for patterns only.
Patients with cervical dystonia report that sometimes to enable a sensory trick such as lifting the head, they squint. Those in pain report that they sometimes cope by wincing, squinting nearly by reflex. It is unclear whether these two phenomena are more common in dystonia but there may be a link worth examining.
Those whose heads tilt report they are often less aware of objects on one side. Those whose heads tilt up may be able to only take occasional glimpses of what is at their feet. Those whose heads tilt down may not easily notice low hanging branches, and often report trouble seeing to go up stairs. In these ways though cervical dystonia does not affect the eyes directly, it may impair vision of the environment.
Patients with vision problems report they are sometimes perceived by the public as if they also cannot hear or process ideas. Some report that strangers immediately talk over them, talk to their companion not them, or who speak slowly and in babyish simplicity when addressing them.
D. Comments from patient experience
first signs
At first. when I had trouble focusing. I thought I just needed glasses
I felt like I had to screw up my eyes and tighten my face muscles all the time
I had eye and nose twitches
I noticed I was blinking a lot and my eyes screwed up a lot
I thought maybe I had an ingrown eyelash
My eyes began to twitch and close
My eyes opened with a lot of squinting and I could not talk well
My eyes were very heavy
One day I suddenly could not see
problem opening eyes or keeping eyes open
I could only hold my eyes open for a few seconds
With no warning my eyes close and I have to work very hard to get them to re open
My eyes just randomly close
I literally cannot open my eyes for any task that is so easy I could do it with my eyes closed.
problem closing eyes or keeping eyes closed
It was hard to close my eyelids
twitches, blinking, spasms
I have no control over the blinking. It’s like hiccups. They just happen
My eyes started twitching a lot
People might think I’m winking at them
The eye muscles felt irritated and I got exhausted from the spasms
eye floaters
My eye floaters make me think I have a bug inside my glasses
My eye floaters are like dust flying all over the place
My eye floaters are creepy, like the walls are crawling
My eye floaters freak me out
impact on daily life
I am not blind but it seems like a type of blindness
It is hard to pour hot tea and dangerous
It is hard for me to focus on the TV screen
My eyes can go into spasm when I use a computer screen
When I tried to talk, the eye problem got worse
treatment
I tried putting ice packs on my eyes to reduce the spasms
I am grateful for the doctor who spotted my problem and acted quickly.
coping
I don’t wear eye make up any more
I now wear dark wrap-around sunglasses outdoors because light triggers the dystonia
Lately I wear dark sunglasses indoors because mall light can give me headaches
When I use a computer I set a dark background with white lettering

J. Analysis
These questions are intended for those with diagnosis of blepharospasm or any other dystonia related eye problem With the high rate of answers marking ‘inapplicable’ it appears that some respondents with dystonia in other body parts may have answered these questions based on some eye involvement but not necessarily official diagnosis of dystonia there. This means the results are not dependable for blepharospasm alone. There may be trends there for blepharospasm but a more differentiated question system would have been useful.
Patients with other areas of dystonia sometimes have some eye involvement. Meige syndrome is dystonia affecting eyes and jaw, tongue and sometimes neck, so some answering may have fit that category.
Answering an online written survey when a person has vision problems would be daunting. It is likely that those who did respond went to considerable trouble to do so, possibly getting help with reading. A survey of people with vision problems using spoken question and spoken response would likely be useful.
