Limitations of blue field entoptoscopy in evaluating macular function.

Evaluation of macular function in cataract patients using blue field entoptoscopy (BFE) has been reported as useful in all cases by some authors; another found it useful only in patients with moderate visual acuity loss due to cataract. This paper reports findings in 101 cataractous eyes evaluated consecutively with BFE. A strong correlation was found between cataract type and percentage of false negatives, but the correlation between the preoperative acuity level and percentage of false negatives was poor. BFE was also poor in detecting moderate macular dysfunction (20/60-20/80). Four cases with profound visual acuity loss due to macular holes had normal perception of BFE.

Blue field entoptoscopy and VER in preoperative cataract evaluation.

Blue field entoptoscopy (BFE) has been described as an effective method for evaluating macular function in patients with dense cataracts. We evaluated 150 preoperative cataract patients with BFE, and found the commercially-available instrument (MIRA BFE 100) to be accurate in patients with 20/400 or better preoperative acuity. There was a high percentage of false negative BFE results in patients with dense cataracts, and light flash VER testing was found to correlate better with attainable postoperative acuity in these patients.
