Changes in choroidal thickness and optic nerve head morphology after filtering surgery: nonpenetrating deep sclerectomy versus trabeculectomy.

Background: The purpose of this study was to evaluate the changes in choroidal thickness and lamina cribrosa position after nonpenetrating deep sclerectomy (NPDS) and trabeculectomy.

Methods: Twenty-three eyes with glaucoma that required filtering surgery were included (12 NDPS and 11 trabeculectomies) in this prospective observational study. OCT-enhanced depth imaging (OCT-EDI) was used to measure choroidal thickness, prelaminar tissue thickness and lamina cribrosa position before and 7 days and 1 month after surgery.

Measurement of subfoveal choroidal thickness after cataract surgery in enhanced depth imaging optical coherence tomography.

Purpose: To compare subfoveal choroidal thickness (SFCT) before and after uneventful cataract surgery using enhanced depth imaging optical coherence tomography (EDI-OCT).

Methods: A prospective study was conducted on 115 eyes of 95 patients who had phacoemulsification. Measurements of SFCT were performed preoperatively, 1 day (D1), 7 days (D7), 1 month (M1), and 3 months (M3) after surgery using the EDI-OCT technique.
