Eye floatersEye floaters are the visual perceptions of spots that swim or move on your visual field. They are very common and usually do not cause any complications What are the causes of eye floatersThere are causes that occur as a natural aging process and causes that occur due to pathological diseases or changes1- Natural causesA- Vitreous syneresisThe eye consists of two segments, the anterior segment which lies infront of the lens and is filled with aqueous humor which is a translucent fluid that is secreted by ciliary process while the posterior segment is filled with vitreous humor...... Read moreB- Posterior vitreous detachmentAnother normal mechanism of floaters is posterior vitreous detachments or PVD. Normally there are adhesions between the back surface of the vitreous or posterior vitreous face and the retina..... Read moreC- MigraineCan cause transient floaters which can remain from few seconds to few hours and usually can be associated with flashes of light and your doctor should be able to differentiate between migraine as a cause of floaters or retinal detachments because both are associated with flashes of light2- Pathological causes in the vitreous.Floaters can also be caused by abnormal deposits in the vitreous which can be white blood cells, red blood cells, drug remnants, parts of the cataract and retinal flaps..... Read more3- Pathological diseases in the anterior segmentCorneal opacities can give the perception of black spots in the visual field but these black spots do not move with eye movements. The presence of foreign body on the cornea also can give the perception of black spots. Hemorrhage in the anterior chamber due to iris neovascularization or trauma, parts of the cataract after cataract surgery, silicone oil droplets or gas bubble in the anterior chamber after vitrectomy surgery; all can give the perception of floaters4- Pathological diseases on retina and/or optic nerve and visual pathwayRetinal diseases and diseases of the optic nerve and visual pathway from the optic nerve to the brain can cause defects on visual field which will be seen by the patient as black spots or patches of varying sizes. Those spots do not move with eye or head movements and can be mistaken as floatersTreatments of eye floatersTreatments of the floaters will depend mainly on the causes of it1- Natural causes like vitreous syneresis and complete posterior vitreous detachment By brain adaptation, in which your brain will ignore the presence of these floaters and you will no long see them. Till now there are eye drops or medications can be used to treat floaters that are caused by natural process 2-After Resolving uveitis and vitreous hemorrhage. By natural absorption process of the eye 3-Active uveitis and intra-ocular infections. By treating the underlying causes 4-Vitrectomy It is the surgery to remove the vitreous. It is indicated when there are large amounts of deposits in the vitreous that did not cleared with time or medications and affect the vision of the patient. Also cataract remnant in the vitreous should be removed by vitrectomy. Also we can use it to remove silicon oil droplets 5-As we said earlier, any patient who noticed floaters for the first time or floaters that occur with flashes of light or sudden increase in the numbers and sizes of the floaters should seek medical advice as soon as possible to rule out retinal detachment and other ocular diseases
