Too busy to read the Lens? Listen to our weekly summary here! In this week’s episode we discuss:

• Circumpapillary retinal nerve fiber layer predicts visual field loss early in glaucoma, while macular ganglion cell inner plexiform layer becomes more informative with advancing disease.

• Although intraocular pressure has been proven as a continuous risk factor when treating glaucoma, the historic intraocular pressure cutoff of 22 millimeters of mercury is used by many clinicians as an inflection point for initiating or escalating intraocular pressure-lowering therapies in glaucoma patients. 

• Elevated aqueous humor L-lactate in uveal melanoma may reflect tumor metabolism, offering a potential noninvasive biomarker for early lesion detection.
