Branch retinal vein occlusion (BRVO) diagnosis

If you are worried about your vision or experience sudden vision loss, see an eye care professional as soon as possible.

Who can diagnose and treat BRVO?

  • Optometrists are doctors who primarily focus on vision and eye health; they can identify conditions like BRVO and provide referrals to the specialists who treat it
  • Ophthalmologists are doctors who specialize in vision care and are specially trained to provide the full spectrum of eye care, from eye exams to eye surgery and BRVO treatment
  • Retina specialists are ophthalmologists who have gone on to receive additional training in diseases of the retina and are highly skilled in both surgery and treatment of diseases that involve the delicate structures inside the eye, and this includes BRVO

Tips for living with BRVO

Enlarging objects

You can purchase large-print playing cards, bingo cards, crossword puzzles, calendars, TV remotes, and other such commonplace items that may be difficult to use if your vision is declining. You can also sit closer to the TV or, if you are going to a movie or a performance, get a seat up front.

BRVO tests

There are several common tests that eye care professionals use to detect and identify the extent of BRVO.

Fluorescein angiography (FA)

This test takes images of the eye to evaluate the blood flow in the back of the retina, which can affect the type of treatment you need

Optical coherence tomography (OCT)

This test uses a special camera to take cross-section images of the eye and measure the thickness of the retina to identify the extent of damage within the eye
