To the Editor.
—I am sorry that Dr. Sohan Singh Hayreh has been offended. I wonder if there are any other ophthalmologists, either American or British, who really believe that any type of catheterization technique is a "safer procedure for injection" than the direct antecubital vein method.The following material is a portion of the Annual Review to which Dr. Sohan Singh Hayreh is referring:Why do the English still use a catheter? In the United States, fluorescein angiography is usually performed by direct venous injection (via the antecubital vein). The English again report injecting through a catheter passed through the right brachial artery into the in-nominate artery. A solution of heparinized 5% sodium fluorescein (0.5 to 1.5 ml) is used and all patients are hospitalized for the study. The dye is said to pass through the retinal vessels as a compact slug with a high peak concentration allowing visualization
