To study the influence of the different surgical intraocular light sources on the functional outcomes of the surgical treatment of macular holes.
Study included 260 patients (310 eyes) with macular holes (Mean±St.D.) 405±45µm in diameter. All patients underwent central 25-guage pars plana vitrectomy with internal limiting membrane peeling and air tamponade. For the vitreoretinal illumination during the vitrectomy, xenon light source was used in 169 eyes (group I) and mercury-vapor light source was used in 141 eyes (group II). All surgeries were performed by one surgeon.
In the surgery of full-thickness macular holes, xenon light causes greater light damage than the mercury-vapor light.
