Seventy-three out of a hundred Malaysians on phenothiazines for more than 24 months had ocular pigmentation. Seventy-one had conjunctiva pigmentation. No pigmentary retinopathy or visual impairment was detected. Frequency of pigmentation increased with age and with higher total dosage prescribed, but there was no critical level below which pigmentation was not detected.
