We describe an uncommon cause of paraneoplastic optic neuropathy in adenocarcinoma of the lung. A 45-year-old healthy woman presented with seizure and encephalitis, followed by an acute visual loss in both eyes for 1 week. Her visual acuity was no perception of light in the right eye and hand movement in the left eye. There was a generalised restriction of extraocular muscle movements in both eyes. Funduscopy showed a bilateral pale optic disc. A paraneoplastic antigen autoimmune profile showed a positive anti-CV2/CRMP-5 antibody. CT of the thorax revealed the presence of right apical lung mass, confirmed to be adenocarcinoma through a biopsy. She was scheduled for lung lobectomy and chemotherapy. Unfortunately, her health deteriorated and she passed away eventually.
Sclerosing rhabdomyosarcoma presentations are widely variable and non-specific initial features. We report a rare case of non-orbital sclerosing rhabdomyosarcoma presented with optic neuropathy. A 15-year-old female patient initially presented with upper gum swelling and pain for 3 months. It was associated with loosening of teeth. Subsequently, the patient developed recurrent epistaxis follow by left facial swelling and blurring of vision. Examination showed marked left facial swelling with mild proptosis. Visual acuity in the left eye was no perception of light with the presence of relative afferent pupillary defect. Fundoscopy showed left optic atrophy. Neuroimaging showed large aggressive soft tissue mass on the left infratemporal, masticator, and parapharyngeal space with a local extension to the sphenoid sinus. There was also an intracranial extension to the left temporal lobe with the base of skull bone destruction. Transnasal endoscopic biopsy revealed sclerosing rhabdomyosarcoma. Management was with chemotherapy. Sclerosing rhabdomyosarcoma may present with optic nerve involvement that may carry a guarded prognosis to the eyes.
A woman in her 70s presented with reduced vision in her left eye, progressive narrowing of right eye opening for 6 months and anosmia. On examination, she had right enophthalmos and pseudoptosis with inferior globe dystopia. Her visual acuity was 6/9 and nil light perception in the right and left eyes, respectively. Extraocular muscle examination showed limited right up gaze. Funduscopy showed a normal right optic disc and left optic disc atrophy. Systemic examination revealed left breast ulceration with skin tethering. CT revealed an infiltrative mass invading the ethmoidal sinuses, frontal sinuses and both orbits. A histological diagnosis of infiltrative ductal breast carcinoma was made after nasal endoscopic and left breast biopsy. She underwent palliative chemoradiotherapy and survived with good disease control after 1 year. Metastatic carcinoma is a differential diagnosis of a sino-orbital mass, and comprehensive clinical assessment is indicated for all patients presenting with non-acute eye injury.
A devastating ocular injury can be caused by durian, the "king of fruits." We report a case of open globe injury secondary to a durian fruit fall. A 54-year-old unfortunate male was accidentally hit by a durian fruit that fell from a tree. The fruit hit directly his right face and eye. He experienced a transient loss of consciousness. He sustained extensive corneal and multiple scleral lacerations with total hyphema, iridodialysis, posterior dislocation of the lens, and retinal detachment. There were also multiple sites of a puncture wound on the right side of the face and right upper lid laceration. Primary suturing of corneal and scleral laceration with anterior chamber washout was performed. The right visual acuity remained poor postoperatively. Durian fruit injury to the eye may lead to severe devastating ocular complications that lead to blindness. The prognosis depends on the severity of the injury.
Sinonasal undifferentiated carcinoma (SNUC) is an extremely aggressive malignancy. Extension to the orbit and adjacent structures is common, but isolated visual loss as a presenting symptom is rare. We report a rare case of SNUC with bilateral visual loss as the initial manifestation. A 34-year-old gentleman was presented with acute onset loss of vision in both eyes for one week. It was followed by recurrent headaches and epistaxis. Visual acuity in the right eye was 2/60 and 3/60 in the left eye. Funduscopy showed a bilateral swollen disc. Neuroimaging revealed a large mass in the ethmoidal sinus extended laterally causing compression to recti muscles and the optic nerves. The histopathological examination of nasal tissue biopsy showed features of SNUC with bone and perineural invasion. A diagnosis of SNUC with bilateral compressive optic neuropathy was established. The patient underwent tumor debulking and base of skull reconstruction by the neurosurgical team. This was then followed by chemotherapy and radiotherapy. The patient's right eye visual acuity initially improved to 6/9. However, his both eye vision developed into no light perception during treatment. In conclusion, SNUC is a highly aggressive tumor that may present with acute blindness. Early treatment may save a life, but the visual prognosis is guarded due to extensive optic nerve damage caused by tumor compression.
We describe a rare case of a patient with systemic lupus erythematosus (SLE) with functional visual loss (FVL). A 30-year-old female had blindness in the left eye due to multiple episodes of optic neuritis with underlying SLE. She presented with blurred vision in the right eye after an upper respiratory tract infection. The visual acuity in the right eye was 6/24, while the left eye had no light perception. The right eye optic nerve function tests were within normal limits. There was a positive relative afferent pupillary defect in the left eye. Fundoscopy showed left optic atrophy, while the right fundus was normal. The patient was treated according to a diagnosis of right retrobulbar optic neuritis. However, despite a course of intravenous methylprednisolone, her right visual acuity deteriorated to light perception. A magnetic resonance imaging (MRI) scan of the brain and orbit was normal. The visual evoked potential (VEP) in the right eye was also normal. The patient was suspected of having FVL and was referred to a psychiatrist. She was diagnosed with major depressive disorder after a full psychiatric assessment.
End-stage renal disease (ESRD) is associated with a number of serious complications, including increased cardiovascular disease, anaemia and metabolic bone disease. Optic atrophy secondary to chronic anaemia in ESRD is rare. We report a case of bilateral optic atrophy in a young patient with chronic anaemia secondary to ESRD. A 23-year-old lady with ESRD, presented with progressive blurring of vision in her left eye for a period of six months. Visual acuity in the left eye was counting finger and the right eye was 6/6. Left optic nerve functions were significantly reduced. Bilateral anterior segments and intraocular pressure were normal. Funduscopy showed bilateral pale disc with arteriolar attenuation. The infective, autoimmune and demyelinating screening were negative. Serial full blood count indicated low haemoglobin and haematocrit value. The full blood picture revealed normocytic normochromic anaemia. Neuroimaging was normal. The patient was diagnosed as having bilateral optic atrophy secondary to chronic anaemia due to ESRD. Chronic anaemia is a potential cause of optic atrophy in a young patient with chronic disease. Management of anaemia in such cases is crucial to prevent irreversible complications including optic atrophy and blindness.
