Reversal of cup-to-disc ratio following trabeculectomy using optical coherence tomography imaging: A case series

In this case series, we report the reversal of optic disc cupping in three adults following trabeculectomy. Two patients experienced asymptomatic low intraocular pressure (IOP) postoperatively, while the third patient had intermittently elevated IOP for a month. The reversal of cupping, a rare occurrence in adults, was confirmed through optic disc photography and the use of spectral domain-optical coherence tomography (SD-OCT) imaging, which enhances the objectivity of these findings. Despite these changes in cup-to-disc ratio (C/D), there were no significant changes in visual field indices in any of the patients. This series is SD-OCT documented cases of cupping reversal in adults up to 2 years postoperatively.
