Improved Maddox Rod Test

NOTES, CASES AND INSTRUMENTS
edematous conjunctiva protruding be tween the lids, making insertion of an artificial eye impossible. After six months this had largely disappeared, so that the patient could wear a glass eye with satisfaction. No further attempt was made to ligate the internal carotid as pressure over this region caused numbness in the hands and fainting spells. 520 Commonwealth Avenue. IMPROVED MADDOX ROD TEST WENDELL L.

In using the Maddox Rod the usual procedure is to place a white or pink rod before one eye and ask the patient the relative positions of the streak and the light. If there are any stray sources of light in the room the patient is fre quently confused as he may see more than one streak. This always necessi tates having the streak properly identi fied. If a small unfrosted green glass bulb* is placed opposite the aperture in the muscle-light chimney and a red filter placed over one eye with a white Mad dox Rod over the other, a very ad vantageous and definite combination is obtained, namely; a red light and a green line. As the green color is ob tained from the object there are no no other green lines to confuse the pa tient. Any stray light in the room gives white streaks. This renders the test very simple for the patient as there is nothing to confuse him. For this reason it saves time for the examiner and is in addition more reliable, as the patient al ways tells the examiner immediately about the relative positions of the green line and red light without preliminary explaining as to which is the proper line. *This bulb is made in a candelabra screw base by the General Electric Co. 6 watt, 120 volt, S-6 natural green. An adapter may be used if one is at present using a white bulb with the regular size base.
If there is a frosted glass over the aperture in the muscle-light chimney, it should be removed. The best aper ture with the colored light at 20 feet is one about 8 mm. in diameter. This gives a brilliant green line which can be seen in a well lighted room. This technic is especially useful for momentary un covering of the Maddox rod. Professional Building.

On July 8, 1932, Mr. I. L. came to my office complaining of pain in the right eye. Twenty-one years ago, while work ing, he had had a penetrating injury to this eye. He had lost vision in this eye, at once, but it remained comfortable un til a few days before he came to the office. On examination the right eye ball was found to be totally blind, con gested and tender. The cornea of this eye had a central leucoma of a yellow ish rusty appearance about 4 mm. in diameter. Through the transparent peripheral part of the cornea an oblong mass about 2 mm. by 5 mm., partly attached to the posterior surface of the cornea, was seen in the anterior cham ber. The iris appeared to be atrophied. An x-ray revealed a foreign body in the anterior chamber of the right eye ball. On December 14, 1932, under a deep orbital anesthesia, an incision was made with a Graefe knife in the lower half of the limbus. A flat spoon was in troduced back of the foreign body so as to prevent it from falling into the vitreous in case it were crushed into particles. The foreign body was then caught with a nasal forceps and ex tracted. The healing was uneventful. The foreign body was a piece of steel about 1 mm. X 2.5 mm. in size, weigh ing 0.025 gm. 1930 Wilshire Boulevard.
