Table 3 Side Effects of 755-nm Long-Pulse Alexandrite Laser Combined with 0.5% Timolol Maleate Eye Drops in the Treatment of 74 Cases of IH
Figure 3 Patient 1 After 5 times of topical treatment with 755-nm long-pulse alexandrite laser combined with 0.5% timolol maleate eye drops, the pigmentation appeared, and the pigmentation subsided within 6 months of follow-up. Patient 2 After 755-nm long-pulse alexandrite laser combined with 0.5% timolol maleate eye drops for topical treatment for 6 times, hypopigmentation appeared and returned to normal within 6 months after the end of the treatment.
