Abstract
Purpose
To evaluate the echographic vitreoretinal patterns before and after intravitreal injection of triamcinolone (IVTA) in eyes with opaque media and several pathologies.
Methods
One eye with pseudophakic cystoid macular edema and two eyes with postoperative endophthalmitis and opaque media were examined using B-scan ultrasonography before and after 0.1 mL ITVA (4 mg Kenacort). The obtained images were compared and the two eyes with endophthalmitis underwent pars plana vitrectomy (PPV) the same day. The relationship between intraoperative and echographic findings was evaluated.
Results
Vitreous was relatively anechoic in all three cases before ITVA. Postinjection examination improved visualization of vitreous and posterior hyaloid face (PHF) and revealed vitreoretinal adhesions. The echographic findings confirmed intraoperatively in the two vitrectomized eyes.
Conclusions
Triamcinolone-assisted ultrasonography enhances imaging of the PHF. This method might be useful in cases with opaque media regarding PPV planning and prognosis. It is suggested to be applied in selected cases taking into account the beneficial diagnosis information versus the risks to IVTA application.
