    Abstract:
    We studied the effects of visible (400-750 nm), infrared (750-1100 nm), and ultraviolet (300-400 nm) radiation on the breakdown of the blood-aqueous barrier (BAB) in albino rabbit eyes using fluorophotometry and fluorescein-bound albumin. There was no evidence of BAB breakdown following exposure to visible (158 J cm-2) or infrared (106 J cm-2) radiation. Fluorescence was detected in the anterior chamber 15 min following ultraviolet (UV) (300-400 nm; 37 J cm-2 and 73 J cm-2) and ultraviolet-A (UV-A) (320-400 nm; 45 J cm-2 and 90 J cm-2) irradiation. This fluorescence peaked at 2 hr after irradiation. Reestablishment of the BAB, indicated by no detectable fluorescence, occurred in all animals after 24 hr. There was a significant increase in fluorescence with increasing UV-irradiation dosage in all groups (P less than 0.05). Comparison of BAB breakdown following exposure to ultraviolet 320-400 nm and 300-400 nm in the same dosage (45 J cm-2) indicated that the inclusion of shorter wavelength UV exposure produced a significantly higher degree of BAB breakdown (P less than 0.001).
