Marc D. Myers, O.D., F.A.A.O.
Course Description: Challenging cases involving the adnexa, anterior and posterior segments
will be presented. The latest diagnostic and ocular management strategies will be discussed.
Course Objectives:
1. Ability to identify and differentiate benign versus malignant skin lesions of the adnexa.
2. Ability to identify the etiology and differentiate and treat acute corneal disease.
3. Discussion of the mechanism of hyphema as well as the management of the diagnosis.
4. Discussion of the etiology as well and the diagnosis and management of acute retinal arterial
occlusion.
Course Outline:
I. Skin Lesion Involving the Adnexa
A. Recognition of suspicious skin lesions
1. Lesion that patient reports as being "new" or only recently noticed
2. An existing lesion that grows in size
3. Any pigmented lesion, especially if it is new or enlarged
4. Pearly telangiectatic nodule
5. Area of diffuse hardening or ulceration
6. Lid notch or retracted area
7. Madarosis
B. The "A-B-C" (D-E) rule
1. Asymmetric shape
2. Borders are irregular
3. Color is mottled, not uniform
4. Diameter of the lesion
5. Elevation of the lesion
C. Squamous cell carcinoma (SCC)
1. Accounts for 9% of eyelid malignancies
a. Fair skin, elderly, excessive UV exposure over the course of a lifetime
b. Younger patients, consider UV sensitivity or immunocompromised
2. Patient symptoms and signs of SCC
a. Symptoms may include pain, burning and numbness
b. The lesion may appear as an indurated, opaque nodule, with or without ulceration
c. Location UL: LL (1.4 : 1.0)
d. Most commonly involves the conjunctiva, cornea, and mucous membranes
e. Lesion may involve lymph glands and/or nerves of the head and neck. Signs of
nerve involvement may include facial paralysis, reduced corneal reflex, and
numbness. The Trigeminal and Facial nerves are commonly involved.
3. SCC and METS
a. Rate of involvement is 1.3% to 21.4%
b. Usually a late development in advanced cases
c. Rate depends on depth of invasion, lesion size, location, histology, etiology, growth
rate, immunosuppression, and perineural invasion.
d. More associated with non-actinically induced lesions
4. Differential diagnoses
a. Premalignancies such as actinic keratosis (AK), KA, and Bowen's disease
