<p><strong><em>A unique how-to guide on surgical management of strabismus from top experts in the field!</em></strong></p> <p>Strabismus correction is the third most common ophthalmic surgery in the US, with 1.2 million procedures performed each year. <cite>Strabismus Surgery</cite> by renowned pediatric ophthalmologist Irene Ludwig provides comprehensive coverage of strabismus treatment – featuring state-of-the-art techniques based on recent anatomical research and discoveries. Throughout the text and accompanying videos, an impressive group of contributors share clinical pearls and firsthand knowledge.</p> <p>Recent research shows that strabismus has a mechanical etiology more frequently than previously thought, and that by directly correcting the mechanical defects, more targeted correction is possible than with traditional approaches. Accordingly, the book is organized by mechanism rather than strabismic deviations and patterns. Presented in four parts, each of which is further delineated by sections, this unique textbook includes 36 chapters starting with the fascinating history of strabismus surgery and concluding with future possible treatments.</p> <p><strong>Key Highlights</strong></p> <ul> <li>New surgical techniques designed to correct muscle displacements and muscle defects related to abnormalities of the extraocular muscle pulleys and intermuscular bands</li> <li>Recognition and repair of stretched scar and flap tear</li> <li>A section dedicated to CNS-related causes of strabismus discusses state-of-the-art surgical approaches for conditions including nystagmus and cranial nerve palsies</li> <li>A comprehensive summary of injection techniques using botulinum toxin and bupivacaine to correct strabismus, particularly in otherwise inoperable conditions</li> <li>Ninety strabismus surgery videos demonstrate a full spectrum of basic to advanced techniques</li> <li>Remarkable illustrations beautifully capture the complex anatomy of the eye muscles and pulleys</li> </ul> <p>The mechanistic approaches described in this outstanding resource will help trainees and seasoned ophthalmologists achieve more precise and lasting results.</p> <p>This book includes complimentary access to a digital copy on <a href='https://medone.thieme.com/'>https://medone.thieme.com.</a></p>

Video 5.3 Pulled-in-Two Syndrome (PITS). This 54-year-old woman had consecutive exotropia develop gradually over years, after having undergone bilateral medial rectus (MR) muscle recession as a child for esotropia. During this surgical procedure, bilateral stretched scar repair was being performed. The right MR repair had been performed uneventfully, but during left MR repair, the muscle ruptured in two at the musculotendinous junction, leading to a lost MR muscle. Its retrieval and direct repair are demonstrated in this video. After the surgery, her husband related that she and her family members suffered from other manifestations of collagen weakness with multiple orthopaedic injuries and dysfunction related to joint hypermobility.

Video 5.4 Scar Migration and Rolling of Insertion Due to Excessive Scarring. Patient 2 months after initial repair of large angle exotropia, now with 25 diopters consecutive esotropia. Right lateral rectus muscle had been recessed 9 mm, but upon reoperation, insertion was found migrated posteriorly and rolled backward, due to excessive fibrosis and scar contracture.

Video 19.3 Displaced Medial Rectus Muscles and Esotropia. Video of Case 2, Chapter 19 (Section 19.13.2), showing paradoxical exoshift with medial rectus (MR) myopexy sutures to treat bilateral inferior displacement of the MR muscles.

Video 19.4 LR-SR and Deficiency Possibly Related to Forceps Injury at Birth. A 29-year-old woman had undergone multiple prior strabismus surgeries to treat recurring strabismus, which began as early childhood esotropia. Alignment would be corrected for several years, but invariably recur. The last recurrence was precipitated by pregnancy, which is known to weaken collagen. MRI showed nasal displacement of the superior rectus muscles, and inferior displacement of the lateral rectus muscles, which was corrected surgically with pulley sleeve fusion as shown in this video. This defect may have been related to forceps injury at birth, which is shown in photos.

Video 20.1 Normal Inferior and Medial Rectus Muscles. Composite of several normal inferior rectus muscles, showing reflection of capsule away from muscle, toward the Desmarres retractor. Medial rectus muscles, showing intact capsule to insertion. Full ciliary vasculature and lack of dragging of external tissues are other normal landmarks.

Video 20.3 Correction of 70-Diopter Exotropia with Flap Tear Repair Alone (Sort Of). Video of case 4, which is a repair of bilateral lamellar medial rectus flaps and small right inferior rectus muscle flap, combined with 9-mm recession of the right lateral rectus muscle, resulted in 25 diopters esotropia. This required later lateral rectus muscle advancement, which is seen in Video 5.4.
