Functional and Morphologic Aspects of Intravitreal Triamcinolone for Uveitis-associated Cystoid Macular Edema
Functional and Morphologic Aspects of Intravitreal Triamcinolone for Uveitis-associated Cystoid Macular Edema
Purpose:
To evaluate the effect of intravitreal triamcinolone acetonide (IVTA) on uveitis-associated cystoid macular edema (CME) using high resolution optical coherence tomography (SDOCT) in conjunction with thorough visual function testing.
Methods:
28 patients with uveitis-associated CME were examined before intravitreal triamcinolone injection (IVTA) (v1) and at day 1 (v2), week 1 (v3) and month 1 (v4) after injection. Retinal anatomy was evaluated using Cirrus HD-OCT (Carl Zeiss Meditec). Visual function testing consisted of assessing ETDRS distance visual acuity (VA), reading acuity and reading speed using a standardized German-language test (Radner Reading charts), contrast sensitivity using Pelli-Robson Contrast Sensitivity charts and fundus-controlled microperimetry using the MP-1 Microperimeter (Nidek). Here we utilized a cartesian grid consisting of a central locus and three concentric box-shaped stimulation areas. The changes of retinal anatomy over time were compared to the respective outcome of visual function.
