Oculoplastics questions and MCQs for residents
Oculoplastics, covered in BCSC Section 7 (Oculofacial Plastic and Orbital Surgery), includes eyelid anatomy and malposition, ptosis, eyelid and periocular tumors, the lacrimal drainage system, orbital disease and trauma, and the facial nerve and midface anatomy relevant to periocular surgery.
Board questions lean heavily on anatomy, including the eyelid lamellae, levator aponeurosis and Müller muscle, orbital septum, orbital apex and lacrimal pump, and on recognizing conditions that threaten sight or life: orbital cellulitis, orbital compartment syndrome, thyroid eye disease with compressive optic neuropathy, sebaceous carcinoma masquerading as chalazion or blepharitis, and orbital lymphoma. Management questions test principles such as margin control in eyelid cancer and choosing a ptosis procedure according to levator function.
Use practice questions to connect a clinical photograph or CT image to the underlying anatomy before choosing a treatment. Explanations that walk through a decision pathway, for example ptosis evaluation from marginal reflex distance to levator function to procedure, are especially useful, and weak-topic drills help consolidate the imaging features of orbital tumors and the options for eyelid reconstruction.

High-yield oculoplastics topics for boards
- Eyelid anatomy: anterior and posterior lamellae, orbital septum, lid retractors
- Ptosis evaluation: MRD1, levator function, lid crease, Hering law
- Congenital ptosis: poor levator function, amblyopia risk, frontalis suspension
- Involutional ptosis: levator aponeurosis dehiscence, good levator function, high crease
- Involutional ectropion and entropion: horizontal laxity, retractor dehiscence, lateral tarsal strip
- Basal cell carcinoma: most common eyelid malignancy, margin-controlled excision
- Sebaceous carcinoma: chalazion or blepharitis masquerade, pagetoid spread, Muir-Torre syndrome
- Eyelid reconstruction by defect size: Tenzel, Hughes and Cutler-Beard flaps
- Thyroid eye disease: activity versus severity, smoking, compressive optic neuropathy
- Thyroid eye disease surgery sequence: decompression, then strabismus, then eyelid
- Orbital cellulitis: postseptal signs, ethmoid sinusitis, subperiosteal abscess
- Nonspecific orbital inflammation: diagnosis of exclusion, biopsy atypical or refractory cases
- Orbital tumors by age: infantile hemangioma, rhabdomyosarcoma, cavernous venous malformation, lymphoma
- Lacrimal gland tumors: pleomorphic adenoma excised intact, adenoid cystic carcinoma
- Orbital floor fracture: entrapment, white-eyed blowout in children, surgical indications
- Retrobulbar hemorrhage: orbital compartment syndrome, urgent lateral canthotomy and cantholysis
- Adult nasolacrimal duct obstruction: Jones testing, irrigation, dacryocystorhinostomy
- Canaliculitis: Actinomyces, pouting punctum, concretions on expression
- Facial nerve palsy: lagophthalmos, exposure keratopathy, upper eyelid loading, tarsorrhaphy
- Blepharospasm versus hemifacial spasm: botulinum toxin, imaging for hemifacial spasm
How oculoplastics is examined
Oculoplastics corresponds to BCSC Section 7. On OKAP and the ABO Written Qualifying Examination, questions typically pair a short history with an external photograph, a CT or MRI image or a histopathology slide, and ask for the diagnosis, the relevant anatomical structure or the most appropriate procedure. Anatomy is also examined directly, through the layers of the eyelid and the structures passing through the orbital fissures and foramina.
The EBO Diploma and FRCOphth written papers emphasize safe clinical decision-making: recognizing orbital cellulitis and orbital compartment syndrome, identifying malignant eyelid lesions, and managing thyroid eye disease according to activity and severity. The subject overlaps with ophthalmic pathology (BCSC Section 4) for eyelid tumors and with neuro-ophthalmology for orbital apex and cavernous sinus disease.
Oral examinations often use external photographs and orbital imaging for oculoplastics: describe the eyelid position, report MRD1 and levator function, give a differential diagnosis, then outline investigation and management. Oral case stations let you rehearse that structure and the anatomical explanations examiners probe.
