    Abstract:
    BACKGROUND: There are numerous methods currently available for the management of xanthelasma. These include surgical excision, laser ablation using a variety of lasers and chemical cauterization. However, each method of treatment is associated with particular limitations and side effects. OBJECTIVES: To assess the clinical efficacy and tolerability of different concentrations of topical trichloroacetic acid (TCA) vs. carbon dioxide laser in the treatment of patients with xanthelasma palpebrarum. METHODS: Thirty patients with xanthelasma palpebrarum were classified into four groups, treated by TCA 35%, 50%, 70%, and CO2 laser, respectively. Lipid profile was estimated for all patients. RESULTS: Both TCA peeling 70% and carbon dioxide laser ablation showed more significant clinical efficacy and tolerability with least number of sessions in the treatment of xanthelasma palpebrarum than 50% and 35% TCA peeling. Post-therapy erythema and hypopigmentation were more with TCA 70%. Post-therapy hyperpigmentation was more with TCA (50%). There was a significant improvement in patients with normal lipid profile than those with abnormal profile. CONCLUSION: Both TCA peeling 70% and carbon dioxide laser ablation are highly effective and well tolerated with least number of sessions in the treatment of xanthelasma palpebrarum.
