Basic and Clinical Science Course (BCSC) Section 07 2025–2026

Section 7 of the Academy’s Basic and Clinical Science Course™ (BCSC^®) details the anatomy of the orbit and adnexa and emphasizes a practical approach to evaluating and managing orbital and eyelid disorders, including malpositions and involutional changes. This section covers current information on congenital, inflammatory, infectious, neoplastic, and traumatic conditions of the orbit and accessory structures. This book also reviews key aspects of orbital and eyelid surgery and abnormalities of the lacrimal secretory and drainage systems and activities.

BCSC Section 7 has an expanded discussion and depiction of oculofacial anatomy with detailed images of cadaveric dissections. Increase your understanding with over 170 new photographs and illustrations.

Review key concepts with 28 videos demonstrating the excision of lateral dermoid and medial dermoid excision, white-eyed blow-out fracture, enucleation with orbital implant, incision and drainage of chalazion, and lateral canthal defect repair using O-to-Z flap. This section includes four interactive activities covering the side and top view of the left orbit, eyelid anatomy, and danger zones with filler injections (sample). Both print and eBook users can access to the videos and activities.

Upon completion of Section 7, readers should be able to:

• Describe the normal anatomy and function of orbital and periocular tissues
• Choose appropriate examination techniques and protocols for diagnosing disorders of the orbit, eyelids, and lacrimal system
• Describe functional and cosmetic indications in the surgical management of eyelid and periorbital conditions
