A white-eyed blowout fracture is an orbital floor fracture associated with restriction of ocular motility (suggestive of orbital content entrapment) but with minimal or absence of signs of soft tissue trauma. It can lead to significant patient morbidity. This case involved an 8-year-old boy with a white-eyed blowout fracture following facial trauma. He presented with binocular diplopia and a history of recurrent episodes of vomiting after the trauma and was referred to our centre for a suspected head injury. Visual acuity in both eyes was 6/9. Examination showed minimal left periorbital haematoma with left eye motility restriction on superior and medial gaze associated with pain. CT scan of the orbit showed left orbital floor fracture with minimal soft tissue entrapment. He underwent urgent open exploration of the left orbit and release of orbital tissue entrapment. Post-operatively, the left eye motility restriction improved significantly with resolution of diplopia. In conclusion, a high index of suspicion is crucial in diagnosing paediatric white-eyed blowout fractures due to lack of external ocular signs.
Diplopia

Rheumatoid arthritis (RA) is a multisystemic autoimmune disease which can be associated with visual threatening ocular manifestations. Common ocular associations with RA include necrotising scleritis and peripheral ulcerative keratitis (PUK). Optic nerve involvement otherwise is uncommon, especially as a presenting feature of RA. We report a rare case of recurrent bilateral retrobulbar optic neuritis (ON) with progressive visual deterioration as an early manifestation of seronegative RA. This case posed diagnostic and management challenges due to its unusual presentation and initially inconclusive investigations. The patient was diagnosed with seronegative RA three years after the first eye presentation. Her RA disease activity score (DAS-28) improved after treatment with a disease-modifying anti-rheumatic drugs (DMARDs), and her ON attacks have been controlled since then. However, her visual acuity, visual field and colour vision remained poor after multiple ON attacks. Multidisciplinary care is key to managing such a patient’s condition and its potential disease complications.
