Abstract

Illumination and access of instruments to peripheral fundus are limited by lens in phakic vitrectomy. The purpose of this study was to determine if curved endoilluminator could enhance visibility of peripheral fundus in phakic virectomy. Ten consecutive cases of pars plana vitrectomy were done for vitreous opacity. Indirect laser photocoagluation was done to make four reference points of distance from optic disc to nasal ora serrata. We evaluated the respective extent of nasal peripheral view with the use of curved or straight endoilluminator which was inserted through temporal scleral port. When compared with the straight endoilluminator, the curved endoilluminator enhanced the visualization of peripheral fundus(p<0.05). A curved endoilluminator may be a useful surgical adjunct during the phakic vitrectomy and other advantages and disadvantages of its use are discussed.
