Malignant glaucoma after trabeculectomy. A, Early postoperative period. Note that the central chamber is flat. B-scan ultrasonography did not show any posterior abnormalities. B, The depth in the unaffected eye is shallow, which increases the risk for postoperative malignant glaucoma. C, The pressure in the surgical eye is not significantly elevated because the filtering bleb is functioning.

Tube exposures increase the risk of developing endophthalmitis and should be repaired urgently.

Tight scleral flap sutures. A, Tight flap sutures can cause a low bleb postoperatively. B, A laser goniolens can be used to visualize the suture. C, After the suture is cut with a green laser, the bleb should elevate quickly.

. A, Eye with pupillary block showing anterior bowing of the iris. B, Eye with plateau iris anatomy showing a large, anteriorly rotated ciliary process causing appositional angle closure.

Photograph shows severe corneal edema from elevated IOP in newborn pediatric glaucoma.

Goniophotograph of the anterior chamber angle in an eye with pseudoexfoliation syndrome. Note the Sampaolesi line (black arrows). White arrows indicate the anterior border of the pigmented trabecular meshwork.

Photograph of an eye with Peters anomaly exhibiting central leukoma, which can be confused for corneal edema.

Photograph of corneal diameter measurement using calipers during an EUA.

Optical coherence tomography angiography (OCTA) scans of a healthy eye and glaucomatous eyes with mild, moderate, and severe damage. The OCTA scans show a dense peripapillary vessel network in the healthy eye, illustrated in red and yellow in the color-coded map. Glaucomatous damage causes a decrease in vessel damage and replacement of the red/yellow areas with blue, indicating either absence of vessels or no flow.
