Purpose: We sought to determine whether the Heidelberg Retinal Tomograph (HRT) might be useful within an academic clinical practice in uncovering or confirming NFL defects. We retrospectively compared an analysis of HRT to conventional examination techniques to see if HRT was able to detect defects overlooked in routine clinical practice. Methods: Medical records, HRT analyses, and visual field examinations were reviewed in a masked fashion from consecutive patients seen within a tertiary glaucoma practice. HRT and visual field performance were assessed independently by two experienced observers. Clinical evaluations performed prior to HRT evaluations included NFL examination employing direct ophthalmoscopy and slit lamp 78 diopter evaluations, as well as disc photography. Results: A total of 102 eyes of 60 patients were evaluated (40 definite glaucoma eyes, 56 glaucoma-suspect eyes, 6 non-glaucoma eyes) Nine eyes (8.8%) were found to have NFL defects recognized by screening with HRT. Of these nine eyes, eight (88.9%) were recognized to demonstrate NFL defects by conventional examination techniques as employed in the clinical setting. One additional eye had a NFL defect by physical exam that was not detected by HRT. Conclusions: In an academic practice, the Heidelberg Retinal Tomograph may be helpful in complementing conventional examination techniques in the recognition and documentation of acquired NFL loss. The HRT and a focused examination conjointly yielded the highest number of recognizable NFL defects.
