PURPOSE
To invest characteristics of the clear oil-drop residue observed in the vitreous cavity after intravitreal triamcinolone acetonide injection (IVTA). METHODS: Fifty three eyes which received a IVTA for the treatment of macular edema due to a variety of causes were enrolled in the study. Slit-lamp examination, and dilated fundoscopic examination had been performed in all patients from injection to at least two months. We compared Group 1 (nonpurified triamcinolone injection) to Group 2 (purified triamcinolone injection). RESULTS: The clear oil-drop residues were mainly observed in the superior portion of the vitreous cavity. They attached to cortical fibers of the vitreous or floated in the vitreous cavity, and had a mobility. They had a various size, shape, and existed anywhere. They were present at 3 days initially and decreased in size and number as time goes by. Group 1 had the clear oil-drop residues in 11 eyes of 29 eyes, but Group 2 in 5 eyes of 24 eyes. Eyes in Group 2 had less residues in number. CONCLUSIONS: The clear oil-drop residues can be observed after IVTA and decanting decreased them after IVTA significantly. |
