Medical Issue's Impacting Fingerprint Accuracy

When attention is paid to missed and bad identifications the errors are usually attributed to a lack of knowledge, failure to follow ACE-V or a clerical error. There is very little mention of physical problems that might compromise a persons visual acuity.The reason I bring this up is that very few agencies require vision examinations for employee's on a regular basis. The CDC has been estimated that in 2005 diabetes effected 14.6 million persons in the U.S. with an additional 6.2 million undiagnosed individuals. One of the effects of diabetes is diabetic retinopathy.

The National Institute of Health has indicated that 40-45 percent of Americans diagnosed with diabetes already have some stage of diabetic retinopathy. It's possible to have diabetic retinopathy and not know it. In fact, it's uncommon to have symptoms in the early stages of diabetic retinopathy. As the condition progresses,symptoms can include,blurred vision,fluctuating vision,dark or empty areas, impaired color vision, vision loss. As is clear this condition could lead to a missed or bad identification.
 I did look at the SWGFAST Standards for Minimum Qualifications and Training to Competency
for Friction Ridge Examiners (Latent/Tenprint) but doesn't look at visual acuity. I would suggest that an agency have latent or tenprint examiners vision tested on a regular basis to insure accurate fingerprint analysis.
