While the spikes that are characteristic of COVID-19 are well-documented, researchers have detected a subtle change from the onset of the pandemic in January to May, when the virus ultimately engulfed New York City.

Cataract surgery in patients with coexisting uveitis is more challenging than managing either condition alone. Surgeons must answer a different set of questions and consider alternative management strategies, said Debra A. Goldstein, MD, FRSC, professor of ophthalmology and director of the Uveitis Service, Department of Ophthalmology, Northwestern University Feinberg School of Medicine, Chicago.

In this article, Dr Tanna discusses treatment options for glaucoma patients who do not show satisfactory response to a PGA while taking into consideration the two key therapeutic choice factors: IOP-lowering efficacy and tolerability.

Nicholas J. Volpe, MD, professor and holder of the Adele Niessen Chair in Ophthalmology at the University of Pennsylvania School of Medicine, has been named the new chairman of ophthalmology at Northwestern Medicine, effective Sept 1.

Normal-tension glaucoma (NTG) is a form of primary open-angle glaucoma (POAG) in which there is no known history of statistically elevated IOP; however, the definition of an upper limit of normal IOP is arbitrary. POAG is a multifactorial disease process with pressure-dependent and pressure-independent etiologic factors. In NTG, the pressure-independent factors likely play a more substantial role.

Ophthalmologists do not agree on whether normal-tension glaucoma (NTG) is the same as primary-open angle glaucoma (POAG). Angelo P. Tanna, MD, director of the Glaucoma Service, Feinberg School of Medicine, Northwestern University, Chicago, approached this debate by offering a detailed definition of NTG.

Glaucoma has long been defined as a disease characterized by elevated IOP. That definition, however, is changing to define the disease as an optic neuropathy characterized by a specific pattern of optic nerve head and visual field damage. That's the word from Theodore Krupin, MD, department of ophthalmology, Sorrel Rosin Eye Center, Northwestern University, Chicago.

Las Vegas-The detection of visual field progression is a critically important aspect of the management of glaucoma, yet it remains a major challenge for clinicians, said Angelo P. Tanna, MD, speaking here during a Glaucoma Subspecialty Day program at the annual meeting of the American Academy of Ophthalmology.

Fairfax, VA—The American Society of Cataract and Refractive Surgery (ASCRS) has formed a Retina Clinical Committee to provide members with a resource on the latest advances in retinal treatment.
