Pre-operative anterior segment, fundus, optic disc, and macular optical coherence tomography (OCT) images. In the first picture, it is seen that the trabeculectomy area is intact and there is no hyperemia (a). Left fundus image (b) shows optic disc edema and chorioretinal folds, optic disc OCT (c) shows left optic disc edema and macular OCT (d) shows chorioretinal folds.

The patient's trabeculectomy site was macrocystic and intact (Fig. 1a). However, after 6 months, the signs of hypotonic maculopathy increased dramatically (Fig. 1b). HD-OCT; Carl Zeiss Meditec, Dublin, CA) (Fig. 1c) and the chorioretinal folds in the macula (Spectralis SD-OCT, Heidelberg Engineering, Germany) (Fig. 1d). Hypermetropic shift also became evident.
Trabeculectomy area view during surgery. The first picture shows (white arrow head) the dehiscent at the temporal edge of the triangular flap (a). When the anterior chamber was filled with balanced salt solution from the paracentesis site, there is significant aqueous leakage (black arrow head) from the dehiscent area (b). A pericardial patch graft was placed in the dehiscent area (c) and sutured with 10.0 nylon (d).

When the conjunctiva was gently dissected at the trabeculectomy site, dehiscence of the scleral flap was detected in the temporal margin of the triangular flap (Fig. 2a). Significant aqueous leakage from the dehiscent area was detected (Fig. 2b). The sterile pericardium graft (Edwards Lifesciences, USA) which was cut to fit the dehiscent area (Fig. 2c) and obtained as thinner half layer, was sutured to this area with 10.0 nylon (Fig. 2d).
Post-operative 6th month images of anterior segment, fundus, optic disc, and macular optical coherence tomography (OCT). In the first picture, it is seen that the trabeculectomy area is intact (a). In fundus image, optic disc was normal, and the chorioretinal folds were largely absent. Optic disc OCT (c) shows normal optic disc and macular OCT (d) is close to normal.

In the anterior segment examination, conjunctival bleb was formed in the operation area, Seidel test was negative, and cornea and anterior chamber were normal (Fig. 3a). In dilated fundus examination, decreased disc edema and depth of the choroidal folds were detected (Fig. 3b). Optic disc edema and choroidal folds improvement was observed in disc and macula OCT (Fig. 3c, d).
