Eyelid lesions are common in primary care

Most eyelid lesions are benign, but 5-10% of skin cancers are periocular, with 90% being basal cell carcinoma (BCC) and 5% squamous cell carcinoma (SCC) [1]. Risk factors include age, UV exposure, family history, immunosuppression, and fair skin [1]. Sebaceous carcinoma, malignant melanoma and Merkel cell carcinoma are important but less common eyelid malignancies.

Recognition and clinical evaluation of malignant eyelid lesions is crucial

BCC and SCC often affect the lower eyelid or medial canthus due to sun exposure. Evert the eyelids to evaluate the palpebral conjunctiva and fornix and assess for tissue fixation [1]. Features of malignancy include skin ulceration, telangiectasia, loss of eyelashes, distortion of eyelid architecture, and crusting [1,2]. Assess ocular motility, palpate regional lymph nodes, and scan sun-exposed areas on the face and body for other lesions. Unilateral blepharitis, or recurrent chalazia may masquerade as sebaceous carcinoma. The “ABCDE” criteria (Asymmetry, Border irregularity, Colour variation, Diameter >6mm, Evolution) aids in the evaluation of eyelid malignant melanoma.

Refer lesions with malignant features

Malignant lesions can resemble benign ones, making diagnosis challenging [1]. Refer suspicious cases to an oculoplastic surgeon or dermatologist for biopsy [1,2]. Treatment typically involves surgical excision with clear margins via Mohs or frozen section. For inoperable BCC, vismodegib is an option for extensive disease, while imiquimod may treat superficial cases.

Styes and chalazia are frequent in primary care

Generally, a stye is a painful, red, and pimple-like lesion caused by infection [3], whereas a chalazion is a non-infectious, painless bump on the eyelid [2,4]. Both often resolve with warm compresses (5-10 min, 4-5x/day) and lid massage. Persistent cases (>4-6 weeks) warrant referral to ophthalmology for assessment of comorbid eye conditions (e.g., rosacea keratitis, blepharitis) [4], and possible definitive management with antibiotics, steroids, and/or incision & curettage [3,5]. Good eyelid hygiene, including lid scrubs with baby shampoo, aids prevention [3–5].

Other common benign eyelid lesions include epidermal inclusion cysts, hidrocystomas, seborrheic keratoses and nevi

Cystic, non-ulcerated lesions that transilluminate may be sweat duct cysts (hidrocystomas), while non-transilluminating cysts may be epidermal inclusion cysts. Seborrheic keratoses appear greasy and “stuck on,” with variable pigmentation. Eyelid nevi may have little to no pigmentation, and the presence of protruding hairs is not uncommon.

Joint Statement: Betoptic S Discontinuation

Betoptic S (betaxolol 0.25%) is being discontinued globally by Novartis. Existing Canadian supplies are expected to run out by the end of this year. There is no other marketed betaxolol eye drop in Canada.  Novartis has indicated that this is a global decision and will not be reversed. The discontinuation has already occurred elsewhere across the globe. We have created a small document for our colleagues in anticipation of this change. 

Betaxolol and Timolol provide similar efficacy in treating glaucoma.1 However, timolol (a non-selective beta blocker) can adversely affect pulmonary function whereas betaxolol (a selective B-1 blocker) has less impact on pulmonary function.2 Therefore, betaxolol has been recommended as the topical beta blocker of choice in patients with pulmonary disease (e.g. asthma, COPD). While betaxolol is not widely prescribed, it remains a part of glaucoma control for some patients.  

We hope providers will guide patients through this drug discontinuation. Alternative management strategies may include switching to another class of topical glaucoma medication (e.g. prostaglandin analogue, carbonic anhydrase inhibitor, alpha agonist) if no contraindication exists,3 increasing ocular availability while decreasing systemic absorption of other therapies by eyelid closure or nasolacrimal occlusion,4 laser trabeculoplasty,5 minimally invasive glaucoma surgery (MIGS) or minimally invasive bleb surgery (MIBS),6 or incisional glaucoma surgery.7 Patient needs and availability of treatment will be unique across the country. We thank you, the providers, for continuing to manage excellence in care for all Canadians.

Musculoskeletal Disorders in Ophthalmologists

The COS Ergonomics working group is pleased to share an online resource focused on musculoskeletal disorders in ophthalmologists. Developed by Queen’s University in collaboration with Weill Cornell Medicine, this online module highlights best ergonomic practices and injury prevention.

Why is this important? The physical demands of ophthalmology puts physicians at risk for work-related musculoskeletal disorders (MSDs) due to poor ergonomics.

After this module, participants will:
