RESUMO
Non-arteritic anterior ischaemic optic neuropathy [NAION] is a serious complication of continuous peritoneal dialysis [CPD] which can lead to poor vision and blindness. We report a five-year-old girl who had undergone a bilateral nephrectomy at the age of one year and was on home CPD. She was referred to the Paediatric Ophthalmology Unit of Sultan Qaboos University Hospital, Muscat, Oman, in 2013 with acute bilateral vision loss, preceded by a three-day history of poor oral intake. At presentation, the patient had severe systemic hypotension. An ophthalmological examination revealed severe bilateral visual impairment and NAION. She was treated with intravenous methylprednisolone and normal saline boluses. At a five-month follow-up, the visual acuity of the right eye had improved but vision in the left eye remained the same. Acute bilateral blindness due to NAION while on CPD is a rare condition in childhood. Paediatricians should be aware of this complication in order to ensure prompt management
RESUMO
Sanjad-Sakati syndrome [SSS; Online Mendelian Inheritance in Man [OMIM] #241410], also known as hypoparathyroidism-retardation-dysmorphism [HRD] syndrome, is an autosomal recessive disorder in which prenatal-onset extreme growth retardation, congenital hypoparathyroidism and craniofacial dysmorphism result from mutations in the tubulin-specific chaperone E [TBCE] gene on chromosome 1q42-43. We report unique ophthalmic findings in a two-year-old child with molecularly confirmed SSS, who was admitted to Sultan Qaboos University Hospital in Oman at 11 weeks old with bilateral congenital corneal clouding. The ophthalmic findings in this patient were linked to faulty microtubule assembly in the brain, abnormal intracellular membrane transport and the resulting metabolic derangement seen in patients with SSS
