Causes of Immediate and Early IOP Spikes After Circumferential Gonioscopy-Assisted Transluminal Trabeculotomy Using ASOCT

, ,

Purpose: To report the early postoperative causes of intraocular pressure (IOP) spikes after complete circumferential gonioscopy-assisted transluminal trabeculotomy (GATT) using anterior segment optical coherence tomography (ASOCT). Methods: This was retrospective interventional case series of patients who underwent circumferential GATT by a single surgeon (APR) from 2021 to 2022 at a tertiary eye care in East India and who developed IOP spikes at 1 day-2 weeks (immediate) or early (> 2 weeks– 2 months) after GATT. The intraocular pressure (IOP), glaucoma medications, and angle evaluation by ASOCT at 1 week, and 1 month were compared between the two groups. Results: Thirty-two eyes of 32 consecutive patients, aged 40± 20.1 years (20 exfoliation glaucoma, 9 juvenile open-angle, and 3 developmental glaucoma), that developed IOP spikes between immediate (n=20) or early (n=12) IOP spikes after GATT, were included. Immediate postoperative spikes were seen in 20 eyes due to retained ...

Comparing focal and global responses on multifocal electroretinogram with retinal nerve fibre layer thickness by spectral domain optical coherence tomography in glaucoma

, , ,

Purpose To evaluate first and second order responses on multifocal electroretinogram (mfERG) and with retinal nerve fibre layer thickness (RNFL) on Cirrus spectral domain optical coherence tomography (SD-OCT) in glaucoma. Methods Patients (old and new) diagnosed with primary open angle glaucoma, primary angle closure glaucoma or normal tension glaucoma attending glaucoma services from November 2012 to January 2013 were screened. Ninety-seven eyes fulfilling inclusion criteria were evaluated by Humphrey visual field, Cirrus SD-OCT imaging and mfERG (Veris Science 5.1.10X; EDI, Redwood City, California, USA) for this observational cross-sectional study. The global and averaged quadrant-wise peak-to-trough amplitudes and peak implicit times of the first trough (N1), the first peak (P1) and the second trough (N2) of the mfERG were compared with average RNFL-full circle (FC) or quadrant RNFL thickness in early (mean deviation (MD) >−6 dB), moderate (MD −6 to −12 dB) ...
