phosphenes in eyes from allergies

[Farklefan]

Anybody out there get phenonmena called phosphenes in their eyes when the pollen count is really high? My area is experiencing high pollen and ever since my eyes have been blurry, tired, burning and I see a flash or spark when I go into a dark room. This only happens when I have eye allergies. Could it be from dehydrated dry eyes or from the pollen irritating the eyes. Thanks

Hello,

A phosphene is an entoptic phenomenon characterized by the experience of seeing light without light actually entering the eye. The most common phosphenes are pressure phosphenes, caused by rubbing the closed eyes. Another common phosphene is “seeing stars,” from a sneeze, a heavy and deep cough, blow on the head or low blood pressure.

If you are having pollen allergy,avoid rubbing the eyes as it will lead to phosphenes. Most pollens are windborne; they can often blow indoors (typically through open windows and doors) and trigger allergic symptoms such as allergic rhinitis (hay fever) within your home, not just outdoors.

Diagnosis is done by skin testing. Confirmatory tests is by blood tests (RAST).

Remain indoors when the outdoor pollen levels are highest like windy days. You can also use a pollen and dust mask. Use a clothes dryer instead of hanging the wash outside, where it acts as a filter trap for pollen. Make sure to clean and replace your air conditioner and air cleaner filters regularly. Also effective are various types of air-filtering devices, which can be added to the heating and cooling systems in the home.

You can take OTC anthistaminics like benadryl or zyrtec.You can also use some nasal decongestants but use them for a few days only. Corticosteroids and bronchodilators can also be used. You can also use saline nasal sprays or steam inhalation at home.

Another effective agent that is available by prescription is cromolyn sodium. In severe cases, Immunotherapy is advised.

Hope I have provided you with sufficient information. In case you need any more then pls post us.
