At the slit lamp, the diagnosis cannot wait — and the margin between correct recognition and a week of wrong treatment is often a single discriminating sign you either see or miss. Most corneal references describe what conditions look like. This one tells you how to tell them apart. The Slit-Lamp Discriminator System gives you a structured five-part recognition framework at every major corneal diagnosis — the discriminating signs, the look-alikes most likely to cause error, the clinical decision each finding triggers, and the single locking anchor that commits you to the right call before the culture grows. INSIDE THIS BOOK • The infectious keratitis differential, solved — bacterial, fungal, Acanthamoeba, and herpetic disease each mapped to their discriminating slit-lamp signature, because specialists get this wrong nearly half the time on appearance alone • Subclinical ectasia detection before it becomes iatrogenic — a structured multimodal imaging pathway covering posterior elevation, pachymetric progression, epithelial mapping, and biomechanics, because a single normal topographic map does not clear a refractive surgery candidate • The steroid rule, stated plainly — active herpetic epithelial disease is harmed by corticosteroids; immune stromal disease requires them; this book tells you which is which at the slit lamp • Peripheral corneal melt as a systemic emergency — PUK workup, ANCA, and the vasculitis associations that can be fatal if the corneal sign is read as a local problem • Fungal keratitis recognized before the second antibiotic fails — feathery margins, satellite lesions, added contour, and endothelial plaque, with confocal microscopy and antifungal escalation mapped to disease depth • Crosslinking, DMEK, DALK, and limbal stem cell transplantation — each procedure matched to the diseased layer, with the reconstruction sequence for chemical burns and LSCD that must not be reversed • The Slit-Lamp Discriminator Master Atlas — every discriminating entry from all twenty-five chapters indexed by presenting sign and differential cluster for point-of-care lookup on call This handbook is written for ophthalmology residents, cornea fellows, comprehensive ophthalmologists, and optometrists managing anterior segment disease. If you examine corneas, this is the reference that trains you to see what is there — and act on it correctly.
