Iris Forceps*

NOTES, CASES, INSTRUMENTS
macular area is increased rather than de creased in this condition. This would tend to invalidate the theory that the cause of the macular disease with the pits of the disc is due to interference with the blood supply of the macular area by the pit. Whether or not the increased vascularity is the cause of or the result of the macular degeneration, and whether the macular lesions are due to involvement of the papillomacular bundle by the pit are questions that remain to be an swered.
case of a pit of the optic disc with macular degeneration is presented. Photographs of the normal and affected eye following the in travenous injection of fluorescein illustrate an increased vascularity of the macular area of the affected eye, suggesting an increased rather than a decreased blood flow to the macula in this condition.
SUMMARY
The authors would like to acknowledge gratefully the aid of Dr. Noble J. David in obtaining the fluorescein photographs and suggestions made re garding this work by Dr. W. B. Anderson, Sr.
A brief discussion of pits of the optic disc and associated macular changes is given. A

in all directions. It is perfect for picking up a small prolapse in performing peripheral iridectomy.
This forceps is made on a standard blank with a round sharp cup measuring one mm. across at the end of each blade. It can be pushed into the angle from almost any di rection and the iris seized at any desired point and delivered for excision. There is little danger to the lens capsule, since the closed forceps has a smooth rounded surface * Presented to the 98th annual meeting of the American Ophthalmological Society, Hot Springs, Virginia, May, 1962. This instrument is available through the Storz Instrument Company, Saint Louis, Missouri.
