Treatment of Erythematotelangiectatic Rosacea with Laser and Topical Beta Blocker: A Split-Face Case Study

Introduction: Erythematotelangiectatic rosacea (ER) is the most common rosacea subtype, yet it is the most difficult to control with most standard topical and oral therapies. Case Report: We present a case of a 63-year-old male with persistent facial burning, flushing, erythema, and telangiectasias, consistent with severe ER, unresponsive to a 10-year course of oral doxycycline. Following the twice-daily topical application of timolol maleate and two pulsed-dye laser (PDL) treatments over an 8-week period, both subjective and objective improvements in the patient's ER were observed. Discussion and Conclusions: This case report illustrates timolol maleate as a potential adjuvant to PDL therapy for the management of severe ER. To our knowledge, this represents the first case of ER successfully treated with both timolol maleate and PDL, offering an additional treatment option for patients with this challenging disease.
