Ocular Side Effects of Dermatologic Medications

Overview / Definition Ocular side effects of dermatologic medications refer to adverse reactions affecting the eye due to the systemic or topical application of skin treatments. These side effects can range from mild to severe and may include conditions such as dry eyes, conjunctivitis, and even vision impairment. Epidemiology The prevalence of ocular side effects varies depending on the specific medication used. Topical medications, particularly those containing corticosteroids, retinoids, and certain antibiotics, have been associated with a notable incidence of ocular complications. Systemic therapies, including isotretinoin and biologics, also present risks. Topical corticosteroids: Commonly used in conditions like eczema and psoriasis, can lead to increased intraocular pressure and cataract formation. Isotretinoin: Associated with dry eyes and potential corneal changes. Biologics: Some can increase the risk of infections, including ocular infections. Pathophysiology / Mechanism The ocular side effects of dermatologic medications can arise from various mechanisms: Topical absorption: Medications applied to the skin may penetrate to nearby ocular tissues, especially in cases of eyelid involvement. Systemic effects: Medications such as isotretinoin can cause dryness of mucous membranes, including the conjunctiva. Allergic reactions: Ingredients in topical formulations can induce hypersensitivity reactions affecting the eyes. Clinical Presentation Patients may present with a range of ocular symptoms, including: Dry eyes: A common complaint, often due to decreased tear production. Conjunctivitis: Inflammation of the conjunctiva, which may be allergic or irritative in nature. Visual disturbances: Blurred vision or other visual changes may occur, particularly with systemic medications. Ocular infections: Increased risk of bacterial or viral infections, especially with immunosuppressive therapies. Diagnosis / Workup Diagnosis of ocular side effects involves a thorough c
