Retinal Perfusion, Sensitivity, and Function in DR

Does retinal capillary non-perfusion reliably predict functional vision loss in DR? And does the answer change how retina specialists treat it? In this episode of New Retina Radio Journal Club with VBS, Barton Blackorby, MD; Katherine Talcott, MD; and Hong-Uyen Hua, MD, discuss a prospective longitudinal cohort study examining the association between retinal sensitivity and perfusion over 2 years in patients with DR.

Three Real-World Scenarios in Which a Minimally Invasive Approach Prevailed

In these cases, MIGS was a safer, effective alternative to traditional incisional surgery.

KEY TAKEAWAYS MIGS is not a replacement fortraditional glaucoma surgery, but it has become an essential componentof modern glaucoma care. MIGS can be used to safely and effectively lower IOP, reduce the medication burden, and delay—or even avoid—the need for more invasive incisionalprocedures. Minimally invasive procedures can also preserve future surgical options and allow earlier, more tailored intervention across arange of disease stages. During the past decade, MIGS has evolved into an essential component of the modern glaucoma treatment algorithm. Although trabeculectomy and tube shunt surgery remain indispensable options for managing advanced and refractory disease, MIGS can offer a safer, effective, and strategically sound alternative in numerous real-world situations. This article highlights three case scenarios in which MIGS meaningfully lowered the patient’s IOP, reduced their medication burden, and preserved their future surgical options. SCENARIO NO. 1 A 68-year-old White man presented with an IOP of 39 mm Hg OD. An examination revealed pseudophakia, pseudoexfoliative material in the pupillary margin, and dense (3+ to 4+) trabecular meshwork pigmentation on gonioscopy. OCT demonstrated glaucomatous retinal nerve fiber layer thinning, whereas the visual field was full on standard automated perimetry.
