Retinal Anatomy and Electrode Array Position in Retinitis Pigmentosa Patients After Argus II Implantation: An International Study.

ABSTRACT:

Purpose

To assess the retinal anatomy and array position in Argus II retinal prosthesis recipients.

Design

Prospective, noncomparative cohort study.

Methods

Setting: International multicenter study.

Patients

Argus II recipients enrolled in the Post-Market Surveillance Studies.

Procedures

Spectral-domain optical coherence tomography images collected for the Surveillance Studies (NCT01860092 and NCT01490827) were reviewed. Baseline and postoperative macular thickness, electrode-retina distance (gap), optic disc-array overlap, and preretinal membrane presence were recorded at 1, 3, 6, and 12 months.

Main outcome measures

Axial retinal thickness and axial gap along the array's long axis (a line between the tack and handle); maximal retinal thickness a
