Abstract. Purpose:To report a case of late-infantile form of galactosialidosis. Case:A 2-year 9-month old male child was referred to us for detailed examinations. He had history of normal pregnancy and birth, was free of cosanguinity, and had an 8-year-old healthy sister. He was late in mental and motor development and showed a face simulating gargoyle. He showed decreased activity of beta-galactosidase in leukocytes. Fibroblastic cells in the skin showed decreased activity of catepsin A, beta-galactosidase, and sialidase, leading to the diagnosis of galactosialidosis. Ocular Findings:Both eyes showed mild optic nerve atrophy and cherry-red spot in the macula. The findings remained unchanged until the age of 5 years. His corrected visual acuity remained stable at 0.1 in either eye. Conclusion:Impaired visual acuity in this patient appears to be due to macular dystrophy and optic atrophy.
