Dexamethasone Intravitreal Implant (Ozurdex) in Paediatric Patients with Non-infectious Intermediate Uveitis and Related Cystoid Macular Oedema: Evaluation of Macular Morphology and Function with Six-month Follow-up; a Deeper Role of MfERG?

Ocul Immunol Inflamm. 2022 Jan 2;30(1):234-240. doi: 10.1080/09273948.2020.1794011. Epub 2020 Aug 24.

Abstract

Purpose: To evaluate the efficacy of Ozurdex implant by analyzing macular morphology and function in pediatric uveitis and related cystoid macular edema (CMO).

Methods: Main outcomes were visual acuity, mfERG and photopic ERG response, and central macular thickness. Mean values recorded at each time-point were compared to baseline and correlations between functional and anatomical parameters were evaluated.

Results: Resolution of intraocular inflammation and CMO was achieved in all eyes 1 month after implant without procedure or drug-related complications. Mean visual acuity and mfERG amplitude improved showing a statistically significant difference to baseline values for the first 4 months. Mean central macular thickness showed a statistically significant reduction for all follow-up time. Photopic ERG did not vary significantly. Statistically significant correlation was found between trends of visual acuity, central macular thickness, and mfERG responses.

Conclusion: Correlation found between macular morphology and function confirms the efficacy of Ozurdex in pediatric uveitis.
