Retinoblastoma is the most common intraocular malignancy of infancy which frequently manifests with a white pupillary reflex. We report a case of delayed presentation of a child with retinoblastoma in his left eye because parents thought the change in iris colour in this eye was due to the innocent heterochromia irides that was previously diagnosed in his elder sibling. This late presentation necessitated enucleation of the affected eye followed by chemotherapy.

Scleritis is an inflammation of the outer eye coating that manifests with redness and ocular pain, and tends to be more severe when associated with a systemic collagen disease. Antineutrophil cytoplasmic antibody (ANCA)-positive microscopic polyangiitis is an autoimmune, multisystem, chronic disease characterised by damage to the endothelial lining of small vessels, and can be associated with severe scleritis that necessitates early aggressive therapy to prevent severe ocular complications.
