Floaters
The most common complaint relating to the retina and vitreous is floaters. Floaters cause a variety of symptoms but usually they are described as black lines or spots floating in the vision. Often patients will describe a mosquito or hair in the vision. This occurs spontaneously or after some type of minor trauma. They are actually areas where the vitreous becomes condensed or detached from the retina forming actual floaters in the eye which are then perceived as dark spots. This is a benign condition and, while annoying, usually does not require any procedural treatment. However, floaters can occasionally be associated with other diseases such as retinal tears or detachment, hemorrhage or inflammation. For this reason, any new floaters should be evaluated immediately by an ophthalmologist.
Other common diseases of the retina include diabetic retinopathy which is discussed in the section of diabetes and the eye. Blocked blood vessels can also occur and usually present with acute loss of vision. This sometimes requires treatment with a laser. Retinal tears and detachment may not have symptoms at all but oftentimes present with floaters, flashes and/or loss of vision. Symptomatic retinal tears can usually be treated in the office with a painless laser procedure. Retinal detachment usually requires surgical intervention and, if treated early, can yield very good vision after treatment.
