Abstract: PURPOSE: To observe the persistence of infrared fluorescence after indocyanine green (ICG)-assisted vitrectomy. METHODS: Eighteen consecutive patients underwent ICG-assisted vitrectomy for eyes with macular holes, epiretinal membranes, diabetic macular edema, and macular edema due to retinal vein occlusion. The internal limiting membrane was peeled after staining with 0.42% ICG solution. Postoperative observation of fundus infrared fluorescence was carried out using Heidelberg Retina Angiography (Heidelberg, Germany). RESULTS: Within a few months after surgery, intense fluorescence was observed around the macular hole and on the optic disk, photocoagulation scars, and the optic nerve fiber and was especially strong in the area along the vascular arcade. At the final visit (16-36 months after surgery), 12 (67%) of 18 eyes had infrared fluorescence that included fluorescence corresponding to the macular hole, retinal edema, and photocoagulation scars. The fluorescence over chorioretinal atrophy in a highly myopic eye disappeared compared with the area having an intact retinal pigment epithelium. CONCLUSIONS: Infrared fluorescence from ICG persists for 16 months to 36 months after ICG-assisted vitrectomy. ICG introduced directly into the vitreous cavity may remain in the eye over years. Careful long-term observation for the adverse effects of ICG is needed.

Abstract: PURPOSE AND OBJECTIVE: To report retina tomography after vitrectomy for macular edema in central retinal vein occlusion (CRVO). PATIENTS AND METHODS: Five patients with macular edema caused by CRVO were examined using optical coherence tomography (OCT) through their clinical courses. RESULTS: The retinal thickness through the fixation was reduced in all 5 eyes. Preoperatively, the retina thickness at the foveola was more than 500 microm in three eyes and more than 1000 microm in 2 eyes. The retina thickness was reduced to 311+80 microm within two weeks on average. Visual acuity was improved by two or more lines in 3 of 5 eyes. CONCLUSION: Vitrectomy is worthy of consideration when macular edemas are prolonged in patients of CRVO. OCT is a useful instrument for management and treatment of macular edema.
