PURPOSE: To report a case of unsuccessful transscleral cyclophotocoagulation in a patient with OCA1A tyrosinase-negative oculocutaneous albinism.
OBSERVATIONS: A 35-year-old Asian female with molecularly diagnosed OCA1A (tyrosinase-negative) oculocutaneous albinism and unilateral severe mixed mechanism glaucoma underwent transscleral cyclophotocoagulation on two separate occasions to treat elevated intraocular pressure. The intraocular pressure remained markedly elevated approximately 1 month following two separate treatments of transscleral cyclophotocoagulation while using high energy settings. The poor efficacy of both cyclophotocoagulation treatments was most likely due to a lack of melanin in the setting of oculocutaneous albinism.
CONCLUSIONS AND IMPORTANCE: Cyclophotocoagulation in patients with oculocutaneous albinism is less likely to yield a desired lowering of intraocular pressure due to the absence of melanin.
