A 62 year-old man presents with decreased vision in his right eye and on examination you find the above.

When should you consider ordering a fluoroscein angiogram or OCT in such a patient to determine treatment options?

c --  Usually after 8 weeks and if clinical findings indicate A fluorescein angiogram should be obtained when the hemorrhages have cleared if the patient's vision is still reduced. Tests are usually done 3 months after the event.   Purpose of test is to determine cause of visual loss (macular edema or ischemia). If visual loss is secondary to macular edema, laser photocoagulation in a grid pattern may be of benefit (See BVOS Study Results) . If macular ischemia is responsible for the loss of vision, laser photocoagulation should not be offered to the patient.   A FA is also useful for showing precise site of venous obstruction if surgery is contemplated.   Of note, an OCT can be obtained to follow macular edema.
