This study was undertaken to determine the changes in the opsonic index in the blood serums of patients treated with uveal pigment. The rationale of this treatment has been fully described in various papers by A. C. Woods.1 This author has shown that hypersensitivity to uveal pigment is a constant phenomenon in sympathetic ophthalmia and apparently paves the road for the outbreak of the disease, whatever other factors may initiate the process. Treatment with uveal pigment is designed to eradicate this hypersensitivity—to desensitize the patient. The clinical results of such treatments have been fully reported.2 Likewise, there have been extensive studies on the antigenic properties of uveal pigment, demonstrating the organ specificity of this substance.3 There have, however, been no studies on the mode of absorption of uveal pigment in man. It was to determine this point that this study was undertaken.
