RESUMO
A new endoillumination infusion cannula has been developed that allows for wide field illumination of the retina during pars plana vitrectomy surgery. This frees the surgeon from having to use one of the intravitreal probes for endoillumination when using the bimanual technique in pars plana vitrectomy. This innovative endoillumination source also can be used with indirect ophthalmoscopy, at surgery, avoiding the glare generated by the indirect ophthalmoscope's light beam interacting with the corneal surface and the condensing lens surfaces.

A newly modified endoillumination probe using the Ocutome handle has been developed that has 2.5 times more total light output and over four times more light intensity than the conventional endoillumination probe. The new probe is particularly useful in situations where there is extremely dense vitreous hemorrhage and when one requires additional light for 16-mm cinematography.

In patients treated with oral indomethacin for four weeks after intracapsular cataract extraction, five of 57 eyes (9%) had cystoid macular edema four to six weeks postoperatively as shown by fluorescein angiography. In a control group not treated with indomethacin, 15 of 34 eyes (44%) had cystoid mascular edema. Oral indomethacin, therefore, caused a statistically significant decrease in the incidence of aphakic cystoid macular edema.
