    E94 – Systemic Drugs & Underrecognized Maculopathy - Dr. Seong Joon Ahn

    In this episode of The Retina Channel Podcast, I sit down with Dr. Seong Joon Ahn from Hanyang University in South Korea to discuss a recent JAMA Ophthalmology study examining systemic drugs associated with underrecognized maculopathy. Using a novel two-step approach that integrates pharmacovigilance signal detection from the FDA Adverse Event Reporting System (FAERS) with nationwide health-claims data from South Korea, the study identifies several commonly used systemic medications— apixaban, paclitaxel, ibrutinib, fingolimod, and sildenafil—as being associated with an increased risk of maculopathy. We explore the study's methodology, key findings such as dose-response relationships, and the clinical implications for retina specialists and general ophthalmologists alike, particularly around patient counseling and the potential need for ocular monitoring in patients on these medications.   Kim J, Ahn SJ, Park J, Gower EW, Chung JE.

    E93- Slit-Lamp Detection of PVD: A Simpler Way to Diagnose- Dr. Mohsin Ali

    In this episode, Dr. Mohsin Ali joins us to discuss his recent study on a simpler and highly effective way to clinically diagnose posterior vitreous detachment (PVD) using slit-lamp visualization of the posterior hyaloid membrane. The study compared this technique to the traditional Weiss ring method and OCT confirmation, finding that slit-lamp assessment of the posterior hyaloid was more sensitive, had a higher negative predictive value, and performed comparably in specificity — without requiring special lenses or imaging. Dr. Ali explains how the technique works, why it matters for everyday practice, and how it can improve decision-making around retinal tears, detachments, and vitreoretinal surgery — making a strong case that this should become a core diagnostic skill for all ophthalmologists. The instructional slit-lamp PVD video referenced in this episode is available as supplemental material with the original Ophthalmology Retina publication.
