Is eye floaters an optical problem or neurological or a combination of both?

Patient's Query

Hi doctor,

I am a 35 year old male. I have floaters in both eyes which developed after severe eye infection at the age of 28 with the use of welding light. Previously, I received treatment for stress. I had tablet Cipralex (Escitalopram) 10 mg for around 3 years. Currently, I am not on any such medication. While taking Cipralex, I used to get good sleep and my light sensitivity suppressed. I had undergone brain CT two years and four years ago, both were normal. My MRI and angio of scalp and brain done this year are also normal. I got meningitis vaccination in 2010 due to gulf visa requirement.

I used to get routine eye check up and fundus examination every six months. My eye pressure is maintained at 18/20. In perimetry, there is no glaucoma. I have normal sharp vision of 6/6. I also got OCT recently to check retina. My problems are light sensitivity and disturbed sleep. The light spot does not go away quickly. I am disturbed with dreams at night and no proper sleep. I have sound intolerance too. I would like to know whether my light sensitivity is a neurological problem or optical issue or a combination of both. My neurologist prescribed Flunarizine and Escitalopram for light sensitivity. I am concerned with these drugs as they are SSRI. I am bothered about my light and sound sensitivity along with disturbed sleep pattern. Kindly guide me.

Hi,

Welcome to icliniq.com.

Eye floaters could be due to eye or secondary to brain. As your eye testing has been normal and nothing seen on slit-lamp examination then likelihood of being it from brain is high.

Common eye spots or black spots caused by migraines are sometimes mistaken as floaters. This could explain the reason for you being on Flunarizine (migraine prophylaxis).

Photosensitivity and phonosensitivity (sound) can be seen with migraines. Flunarizine should help you with these. If you feel any benefit then there is a room to improve it by adjusting the medication or changing to other agent.

Since there is a history of severe eye infection (uveitis? or retinitis?), the left over debris can cause floaters. This could be seen on eye examination and helped by an ophthalmologist.

SSRI (selective serotonin reuptake inhibitor) can help you with your sleep, but sometime it increases your dreams. If you are very concerned with your sleep disturbance, it is worth getting a sleep study (polysomnography) and look for formal evaluation.

Your normal MRI of brain is a reassuring thing.
