This is a test routinely used in the evaluation and treatment of glaucoma. ...Read more

I have end stage open angle glaucoma with 130 degree field of vision.  What does this mean..Doctor vague
?

Visual field driving: Severe (end stage) glaucoma causes peripheral vision loss (tunnel vision) . Open angle is most common. Florida requires that you have at least 130 degrees of uninterrupted horizontal visual field in order to drive (along with acuity and other requirements). This is because severe peripheral visual field loss would mean that you might not see a car or person entering the road from the side. ...Read more

Two little black dots in my field of vision that float?

Two little black dots in my field of vision that float?

Floaters: It sounds as if you have had a posterior vitreous detachment. This is a situation where the vitreous(jelly) of the eye detaches (not a retinal detachment), it then "crumples" up leaving dots, spots, strands of blurry vitreous; i.e. The "floater". You should have an exam to ensure the incident did not tear the retina, which could lead to a retinal detachment. Wait one year then consider surgery. ...Read more

What is the field of vision threshold and what does it have to do with anything?

What is the field of vision threshold and what does it have to do with anything?

Vision map: The visual field exam, taken in a dome like apparatus, maps out the sensitivity of the retina at a broad array of points. It produces a sensitivity MAP like an altitude MAP of a mountain range, which can estimate the health of the retina and also changes in the sensation reception of the brain. Regular fields are done in conditions like glaucoma to estimate progression of loss. ...Read more

What could cause someone to see small, bright dots of light in their field of vision?

What could cause someone to see small, bright dots of light in their field of vision?

May be serious: Bright dots are potentially a sign of a retinal tear or detachment and immediate evaluation is indicated. Other possible causes include intraocular inflammation and stimulation of the retina due to normal aging changes of the vitreous gel in the back of the eye. If you are currently seeing bright dots, call an eye doctor immediately. ...Read more

Why do I see colors in the field of vision every time i look into a bright light?

Visual phenomenon : Bright light bleaches the cells in the retina which relay information to the brain. When bleached, the nerve signals they emit are not accurate of the outside world. They cause the brain to interpret persistent colored lights, this fades as the cells recover. ...Read more
