A 47-year-old Hispanic patient presented with painless vision loss in his left eye over a period of two months. His visual acuity and intraocular pressure were normal, slit-lamp examination revealed a curvilinear dark lens opacity at the infero-nasal quadrant of the left eye…

Newborn with congenital glaucoma (right eye), buphthalmose.

Rubeosis iridis (neovascularization of the iris) form diabetic retinopathy.

Sclerostomy obstruction. A, Patients with iris occlusion of the trabeculectomy fistula will have elevated intraocular pressure and a flat bleb. B, Gonioscopic photo reveals iris in the fistula. C, A peaked pupil should alert the physician to this possibility.

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. Glaucomatou…

Progressive optic disc excavation in a patient with uncontrolled open-angle glaucoma over a 3-year period. The overall size of the optic disc is small. A, The inferior overall cup size is larger than expected for a small optic disc and the inferior neuroretinal rim is thinne…

Epithelial ingrowth appears as a grayish, sheetlike growth on the endothelial surface of the cornea, usually originating from a surgical incision or traumatic wound. The epithelial ingrowth shown here originated from a glaucoma surgery incision, causing peripheral anterior s…

Iris neovascularization. With progressive angle involvement, peripheral anterior synechiae (PAS) develop with contraction of the fibrovascular membrane, resulting in secondary neovascular glaucoma.

An example of an anterior segment OCT scan that demonstrates iridotrabecular contact.

Direct Gonioscopy. a. Koeppe Lens. b. Barkan goniolens, c. Direct exam of angle structures

Subacute angle closure glaucoma. Phacomorphic angle-closure.

Optic disc OD

Glaucomatous optic atrophy. Optic nerve cupping is increased vertically, with a cup–disc ratio of 0.8. Cupping is apparent at the point where the vessels disappear over the edge of the attenuated rim.

Glaucomatous cupping. The patient’s right eye shows a cup–disc ratio of 0.8 (high level of glaucoma suspicion); the left eye shows a cup–disc ratio of 0.6 (moderate level of glaucoma suspicion). The asymmetry of cup– disc ratios here also raises suspicion of glaucoma.

The normal visual field and the maps produced by different types of perimetry. (A) Three dimensional model of the right eye’s “island of vision surrounded by a sea of blindness.” The horizontal plane indicates degrees (circles) of eccentricity and meridians. The vertical axi…

Visual field defects produced by glaucomatous optic neuropathy (right eye). (A) Paracentral scotomata. (B) Superior nasal step. (C) Arcuate scotoma. (D) Advanced peripheral constriction.
