recently i have been experiencing starbursts and halos what may be the cause?

[svenk]

i have been experiencing rainbow colored halos and starbursts around lights at night. my doctor ruled me out of glaucoma(twice) .i also have dry eyes and minimal astigmatism.They gave me dorzox eye drops because i complained that i cant bear that halos. my iop was 26 and i have thick cornea so they said pressure was borderline
i want to know what causes these halos as i am only 20 years old

Dorzox is a glaucoma medication so you are being treated for glaucoma. Possible causes include cornea disease such as keratoconus (you need corneal topography), cataract formation, and macular edema (you need macular OCT)  The problem could also be due to needing glasses, having incorrect glasses or due to side effects of contact lens if you wear them.

the dorzox was given to check whether the halos was due to pressure .but my halos have not reduced.but my doctor told me that the possible causes could be dry eyes,astigmatism ,or glaucoma.she was so sure that my optic nerve was fine. could dry eyes or astigmatism cause starburst and rainbow colored halos.could you explain me your answeragain

[JohnHaganMD]

If your problem is due to dry eyes then after you instill an artificial tear it should go away or be better for half an hour or so. Dry eyes are very rare in healthy males your age.  Astigmatism could cause the problem especially if you do not wear glasses or the glasses are not correct RX or you wear contacts. Since your problems persists I suggest a corneal topography and macular OCT and another look at your lens to be sure its clear (cataracts are rare at your age but can occur in some diseases or families). If you wear contacts that is far and away the most likely cause

doctor  apart from seeing halosand starbursts i dont have any vision problems. whenever i read in internet these conditions equate to glaucoma, but my eye doctor is pretty sure that i dont have glaucoma she gave dorzox saying that the halos should go away if it was due to increased pressure it hasnt so i presume that  it is not caused by pressure
1)i have the following questions
could seeing rainbow colored  halos equate only to glaucoma because i dont have any vision loss( my angles and nerve are normal) problems?
2)can astigmatism cause these ?
3)is cataract possible at my age?
4)can ocular hypertension cause these halos and starbursts
5)can i leave this condition presuming i am normal(which is so according to my doctor)or it is dangerous

[JohnHaganMD]

1. Not glaucoma. Halos occur in angle closure glaucoma and you don't have that 2. yes 3 yes usual though 4 no    and 5 all I can say is generalize about your eye not your general health. No reason not to believe your physician

[svenk]

Doctor suggest me with future course of action
1)can astigmatism cause rainbow colored halos and starburst s ( my doctor said please ignore those halos)
2) is my assumption that it does not occur due to pressure correct
(Because even after drops there is no change)
3)does an anti glare coating glass
help these?

[JohnHaganMD]

1. could if large amount or so called "irregular astigmatism  2. yes   3. not likely

[svenk]

1)is seeing like this vision threatening
2)what would be your final advice for me because there seem to be potentially no solutuion for these ?
finally thanks for taking your time and i really went into depressed state reading that it was due to glaucoma 3)because they said 90% of halos are due to glaucoma is this true?

[JohnHaganMD]

1. Since I can't tell you exactly what you have I can't establish a prognosis. 2. You should get this information from your eye MD ophthalmologist.  3. most halos are NOT from glaucoma.
