X-linked retinoschisis (XLRS) is a rare, hereditary, and bilateral vitreoretinal degeneration, associating maculopathy and vitreoretinopathy. We report the case of X-linked retinoschisis diagnosed after congenital cataract surgery in a child.

Tuberculosis is a frequent disease in Morocco, palpebral localization remains very rare, often poorly managed because of its polymorphism. We report the case of a 6-year-old patient, without any notable antecedents, who presented repeated chalazions. Following frequent recurrences, despite surgical management, the patient benefited from an exeresis biopsy which confirmed the tuberculosis infection. A general check-up was performed to look for secondary localizations of tuberculosis, specifically a pulmonary localization, which was negative. The patient presented a good response to antibacillary treatment. In the light of this clinical case, we recall the importance of an anatomopathological study, which must be systematic before any excision of tissue material in the treatment of a chalazion with atypical localization or notion of recurrence.

Donnai-Barrow syndrome is an autosomal recessive disease due to mutations in the LRP2 gene described by Donnai and Barrow in 1993. We report through this clinical case the various ophthalmologic and extraocular manifestations of Donnai Barrow syndrome which remains a very rare congenital malformation. High myopia is a risk factor for severe amblyopia and/or retinal detachment which requires a regular monitoring. The management of this disabling disease is multidisciplinary, involving the ophthalmologist, the otorhinolaryngologist, the pediatrician and the psychiatrist.
