Spontaneous Necrosis of a Large Choroidal Melanoma: Unusual Presentation in a 49-Year-Old Male.

Purpose: To demonstrate a case of massive vitreous haemorrhage obscuring the underlying diagnosis of a large mixed-cell choroidal melanoma which had undergone spontaneous necrosis.

Case Report: A 49-year-old man in good general health suddenly lost vision in his right eye due to an extensive vitreous haemorrhage 1 day after a workout at the gym. He reported good vision prior to that without any symptoms of flashes, floaters, or shadows.

Hypotension-induced blindness in haemodialysis patients.

Hypotension is a commonly encountered complication in haemodialysis patients and is a significant cause of morbidity and mortality. Bilateral visual loss in dialysis induced hypotension remains poorly recognized as a complication by both renal physicians and ophthalmologists. We report 2 cases of patients on renal dialysis who suffered severe longstanding hypotension with bilateral non-arteritic anterior ischaemic optic neuropathy.

Isolated Pupil-Involving Third Nerve Palsy as the First Presentation of Sarcoidosis.

Neurosarcoidosis is seen in 5-15% of patients with systemic sarcoidosis. The most common cranial nerve presentations are optic neuropathy and facial nerve palsy. The authors present a case of sarcoidosis presenting with a pupil-involving third nerve palsy.

Intracranial hypertension: was it really idiopathic?

A healthy 44-year-old slim female presented with a constant, non-specific dull headache of subacute onset. The examination showed papilloedema but no other problem. On further questioning she revealed transient visual obscurations and pulsatile tinnitus.

Midoperative forced duction test as a guide to titrate the surgery for consecutive exotropia.

This is a retrospective study of the outcome of all consecutive exotropia surgery performed between the years 1999 and 2007. Excluded were cases of slipped muscles, muscle transpositions, and concurrent cyclovertical procedures. A total of 135 patients of mean age 40 years (range 6-72) were operated with a mean preoperative angle of deviation -40Delta (range -12 to -90).

Triamcinolone pseudo-cataract.

This is an interventional case report of a pseudo-cataract formation by the adherence of triamcinolone particles to the posterior surface of the lens following a 2-mg intravitreal injection for treatment of macular edema associated with non-ischemic central retinal vein occlusion. These deposits unusually persisted beyond 6 months.

Chronic paroxysmal hemicrania presenting as recurrent orbital inflammation.

Patients with chronic headache associated with ocular symptoms regularly seek ophthalmologists' opinions. We report an unusual case of chronic paroxysmal hemicrania (CPH), a rare but well-described variant of cluster headache in a female presenting to an eye department with recurrent episodes of severe unilateral periorbital swelling with a chronic history of headaches. Clinical features, review of literature, and therapeutic response to indomethacin helped to establish the diagnosis as CPH.
