Orbital inflammatory disease.

Orbital inflammatory disease (OID), commonly known as orbital pseudotumour, is an inflammatory disease of unknown cause. It has different forms of presentation and different degrees of severity. Its variable nature is the main cause for this disease to be misdiagnosed and misclassified. The prognosis of OID depends on the tissues affected and the histology. OID usually responds favourably to systemic steroid treatment. However, empiric steroids may mask other underlying diseases that respond well to this treatment as well, namely, IgG4-related disease or lymphoproliferative disorders. This fact has led to controversy among various authors as some recommend performing a biopsy in most of the cases, whereas others defend that this procedure should only be performed if the patient has not responded to empiric steroid treatment. Although steroids have been the mainstream treatment of OID, the side effects, relapse rates and lack of response in some cases have resulted in them being replaced by immunosuppressive and immunomodulator therapies that currently stand as a key steroid-sparing treatment option, in addition to radiotherapy and surgery. The aim of this review is to update the evidence on the diagnosis and treatment of OID.

Retinitis pigmentosa as a clinical presentation of LCHAD deficiency: A clinical case and review of the literature.

Long-chain 3-hydroxyacyl-CoA dehydrogenase deficiency is a rare metabolic disease caused by a specific mutation in the HADHA gene, which leads to an alteration in the metabolic pathway of fatty acids. Its most frequent form of presentation at the ophthalmological level is retinitis pigmentosa, and in some cases the ophthalmologist could be the first one to alert the other paediatric specialties to carry out a multidisciplinary approach to the case. The case is presented of a patient with long-chain 3-hydroxyacyl-CoA dehydrogenase deficit detected in neonatal screening, and which clinically debuted as pigmentary retinosis with no alteration in visual acuity as observed in the fundus images and optical coherence tomography of the retina provided. Finally, a review of the literature of this potentially lethal pathology is presented, and the main pathological and clinical features are highlighted.

Haberland syndrome with bilateral ocular involvement. / Síndrome de Haberland con afectación ocular bilateral.

Haberland syndrome or encephalocutaneous lipomatosis is a very uncommon syndrome that is characterised by changes in the skin, eye, and central nervous system. It was first described in 1970 by Haberland and Perou, with about 60 cases having been reported since then. A case is reported of a 14-week-old male diagnosed with Haberland syndrome with bilateral ocular involvement in the form of palpebral coloboma and choristomas.
