Results of a visual field test in a patient with advanced glaucomatous visual field loss. The test with 30-2 pattern (top) evaluates only a few points in the central area. The 10-2 test (bottom) evaluates more points in the central area, allowing better evaluation of potential progression over time in this case.

Example of retinal nerve fiber layer (RNFL) analysis with spectral-domain optical coherence tomography (SD-OCT). Top: The right eye shows diffuse RNFL thinning on SD-OCT (A), which is consistent with the neuroretinal rim thinning and enlarged cup seen in the photographs of the optic nerve head (B) and with the visual field loss that is evident on standard automated perimetry (SAP) (C). Bottom: The left eye shows normal RNFL thickness on SD-OCT (A), normal appearance of the optic nerve head (B), and normal visual field (C).

Findings from a right eye with glaucoma. A, Inferior RNFL thinning is visible on OCT. B, SAP shows a small corresponding superonasal visual field defect that is more pronounced on frequency-doubling technology perimetry (C) and Heidelberg Edge Perimetry (D).

A, Photograph of the optic nerve head shows marked neuroretinal rim thinning and an enlarged cup; however, SAP (B) shows that the visual field is still within normal limits. C, The RNFL analysis with SD-OCT shows diffuse loss of the RNFL

AbbVie has agreed to acquire Allergan for $63 billion, unlocking key opportunities for growth on both sides of the deal.

In this webinar, Drs. Patel, Camejo, Blieden, Shen, and Reznik provide the comprehensive ophthalmologist with an overview of some of the major advances in the diagnosis and management of glaucoma.

In this 1-Minute Video, Dr. Ron Fellman shares tips about aqueous misdirection syndrome.
