E93- Slit-Lamp Detection of PVD: A Simpler Way to Diagnose- Dr. Mohsin Ali
About this episode
Dr. Mohsin Ali discusses a simpler and effective method for diagnosing posterior vitreous detachment using slit-lamp visualization.
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.
