Objectives: Data obtained mostly from animal models and ex vivo samples
show that a small portion of ultraviolet light (UV, 300-400 nm) penetrates
the cornea and crystalline lens and impinges on the human retina. UV
transmission to the retina appears to be unique to the young and some
older pseudophakes. In this study, we determine the variation in UV
transmission in a relatively homogenous sample of young adults. Methods:
42 subjects were tested (M = 19 ± 1.3 years). Absolute thresholds to UV
radiation were collected (max = 315 nm, 305-325). Macular pigment optical
density (MPOD, measured using heterochromatic flicker photometry) and iris
color (using a standardized color scale) were also assessed as potential
covariates. Results: All of the subjects could detect UV radiation at 315
nm but individual variation was large (over a factor of 30). Higher MPOD
and darker iridies were not related to UV sensitivity in this young
sample. Males, however, were more sensitive to UV than the females
(p<0.05). Conclusions: The large individual differences in UV
reaching the retina of younger individuals suggests equally significant
vulnerability to the actinic effects of this highly energetic light.
