Indirect ophthalmoscopic assessment of the optic nerve head and retinal nerve fiber layer at the slit lamp should, whenever possible, be augmented by other techniques such as direct ophthalmoscopy, retinal photography, and/or scanning laser ophthalmoscopy. 

Retinal photography is an important adjunctive tool in the assessment of the optic nerve and retinal nerve fiber layer. 

Disc (Drance) hemorrhages and retinal nerve fiber layer defects that are visible with retinal photography can be overlooked during clinical and/or laser ophthalmoscopy. 

More disc hemorrhages detected on retinal photography vs. ophthalmoscopy by an expert clinician. 

There has been a report of retinal changes in 60 users of crack (164). Microtalc retinopathy and retinal nerve fiber layer rake or slit defects were detected by threshold visual field testing and fundus photography.
