Answer

Look for nerve fiber layer defects/dropout.

Techniques are as follows:

  • Ophthalmoscopic examination with red-free (green) filter

  • Good color photography

  • Red-free photography

Instruments for retinal nerve fiber layer analysis are very accurate, but they are expensive. [29] Sehi et al have shown that progressive atrophy of the retinal nerve fiber layer has been associated with subsequent visual field loss. [30] Miki et al found that faster retinal nerve fiber layer thinning corresponded to an increased risk of developing visual field defects. [31]
