How to photograph and evaluate the retinal nerve fiber layer
Journal of the American Optometric Association
|October 1, 1986
Summary
Early glaucoma detection is possible by examining the retinal nerve fiber layer (RNFL) using short wavelength light photography. This method allows for slide-mounted negative evaluation, avoiding expensive printing and enlarging processes.
Area of Science:
- Ophthalmology
- Medical Imaging
Background:
- Retinal nerve fiber layer (RNFL) defects are early indicators of glaucoma.
- Short wavelength light black and white photography is a key diagnostic tool.
Purpose of the Study:
- To describe the methodology for photographing and evaluating the RNFL.
- To present a cost-effective method for RNFL assessment.
Main Methods:
- Utilizing short wavelength light for black and white photography to capture RNFL details.
- Mounting photographic negatives as slides for examination.
- Employing a slit lamp for detailed analysis of the mounted RNFL slides.
Main Results:
- The described photographic and evaluation technique effectively reveals RNFL defects.
- Mounting negatives as slides for slit lamp examination provides a viable alternative to traditional printing and enlarging.
Conclusions:
- RNFL photography with short wavelength light is a valuable tool for early glaucoma detection.
- Slide-mounted negative examination with a slit lamp offers an economical approach to RNFL analysis.
