The incidence of ocular trauma in far north Queensland is equal to other Australian populations. However, there is a disproportionately high incidence in the Aboriginal and Torres Strait Islander population. Alcohol-related assault is a significant cause of visual loss in the Aboriginal and Torres Strait Islander population. Closed-globe injuries are more common than open globe; however, the latter have poorer visual prognosis. Initial visual acuity of all injuries correlated with final visual acuity.

BackgroundConjunctival myxomas are rare, benign, connective tissue tumours that classically present as slow-growing, painless, well-circumscribed masses (Arch Ophthalmol 124:735-8, 2006; Case Rep Ophthalmol 3:145-50, 2012). There have been 29 cases reported in the literature (Arch Ophthalmol 124:735-8, 2006; Malays J Med Sci 20(1):92-4, 2013; Case Rep Ophthalmol 3:145-50, 2012; Middle East Afr J Ophthalmol 19(3):353-3, 2012). We present a case with atypical features, and emphasize the importance of excisional biopsies for diagnosing indeterminate conjunctival lesions.Case presentationA 32 year old Korean woman presented with a 5 mm × 7 mm × 3 mm pedunculated firm cystic lesion on the inferior palpebral conjunctiva of her right lower eyelid. The lesion had rapidly enlarged over the course of a week. She gave a history of uncomplicated bilateral epiblepharon correction performed in Korea three months prior. There were no systemic features, or family history of genetic conditions. The lesion was excised under local anaesthesia and reported to be a conjunctival myxoma.The clinical and histopathological features of this lesion were consistent with previous reports on conjunctival myxoma (Arch Ophthalmol 124:735-8, 2006; Arch Ophthalmol 101:1416-20, 1983; Case Rep Ophthalmol 3:145-50, 2012; Am J Ophthalmol 102(1):80-84, 1986). The unusual features of this case were, the rapid growth of the lesion - with the previously documented mean time before presentation being 34 months (range 3 months - 24 years) (Arch Ophthalmol 124:735-8, 2006; Case Rep Ophthalmol 3:145-50, 2012); the location of the lesion in the inferior palpebral conjunctiva - 93 % of previously reported cases had occurred in the bulbar conjunctiva (Arch Ophthalmol 124:735-8, 2006; Case Rep Ophthalmol 3:145-50, 2012); and its occurrence in association with recent eyelid surgery - which has never been reported.ConclusionThis case of conjunctival myxoma adds to the small number of documented cases, by demonstrating an atypical presentation. Conjunctival myxomas can occur in association with the Carney Complex, which is an autosomal dominant syndrome associated with benign tumours, spotty mucocutaneous pigmentation, and endocrine overactivity (Ophthalmic Surg Lasers Imaging 39(6):514-6, 2008). Ophthalmic manifestations of the Carney Complex have been found to precede vascular embolic events secondary to cardiac myxoma, thus early diagnosis of conjunctival myxoma can prevent potentially devastating consequences (Ophthalmic Surg Lasers Imaging 39(6):514-6, 2008). The different presentations of this rare tumour emphasise the importance of excisional biopsies in diagnosing indeterminate conjunctival lesions; and its association with cardiac myxoma, highlights the need for cardiac investigations in all patients who present with conjunctival myxoma (J Ophthalmol (1);1-5, 2014; Ophthalmic Surg Lasers Imaging 39(6):514-6, 2008).

These results suggest that cobalt-chromium toxicity can cause inner retinal dysfunction.

Importance: Indigenous communities of Far North Queensland (FNQ) have one of the highest incidences of alcohol-related ocular trauma globally. Background: To review the epidemiology of closed-and open-globe trauma admitted to Cairns Hospital from FNQ health districts following the implementation of alcohol restrictions in Indigenous communities. Design: Retrospective study of cases from January 2014 to December 2018. Participants: A total of 142 cases identified from ICD-10 clinical-coding data. Methods: Records were reviewed to determine demographics, clinical details and outcomes. Main Outcome Measures: Annual incidence by demography and ethnicity (Indigenous vs non-indigenous). Results: Estimated annual incidence was 10.4/100 000 population (openglobe: 3.6/100 000, closed-globe: 6.8/100 000 population). Incidence rate ratio was 2.8× higher in Indigenous (22.8/100 000 population) compared to nonindigenous populations. Injury from assault was 8.2× higher in the Indigenous population. Alcohol was involved in 76% of assaults. Paediatric injuries comprised 20.4% of the cohort, with Indigenous children over-represented (44.8% of children). Visual acuity (VA) at presentation ranged from −0.08 logMAR to no-perception of light (NPL), with 41.8% poorer than +1.00 logMAR. Final VA ranged from −0.18 logMAR to NPL. Mean final VA was significantly better for closed-than open-globe injuries (+0.43 vs +1.01 logMAR). Ruptures had the poorest outcomes (mean +1.65 logMAR). Conclusions and relevance: The overall incidence of severe ocular trauma in FNQ has decreased compared to that reported from 1995 to 2002. The extremely high incidence observed in the Indigenous communities of Cape York has decreased dramatically since the introduction of Alcohol Management Plans. Nevertheless, the Indigenous population still experiences significantly higher rates of severe ocular trauma, particularly from assault.

Aeromonas sobria infection should be suspected in water-contaminated penetrating eye injuries. The prognosis in this case was poor.

Background Nocardia farcinica is one of the more recently identified species of the Nocardia genus. Nocardia farcinica keratitis is a rare occurrence, with only eight previously reported cases. Semi-permeable rigid contact lens use was associated with one of these reported cases. We report the first case of extended wear soft contact-lens-related Nocardia farcinica keratitis and recommend a new treatment regime.FindingsA 47-year-old lady presented with a right eye keratitis after wearing her extended wear soft contact lenses for five continuous weeks. There was no history of trauma or swimming with contact lenses in. Empirical ciprofloxacin and tobramycin eye drops were not tolerated due to ocular surface irritation on application; and instead, empirical treatment was with chloramphenicol and fortified gentamicin 1.5 % eye drops. Corneal scrapings grew Nocardia farcinica after 3 weeks—sensitive to amikacin and co-trimoxazole. Treatment was changed to amikacin 2.5 % eye drops, resulting in partial resolution of the corneal infiltrates. Oral co-trimoxazole 160/800 mg BD was added, due to cultured drug sensitivity and its high ocular penetration, with good results and a final right eye best-corrected visual acuity of 6/5.Conclusion Nocardia farcinica keratitis should be considered in the differential diagnosis of contact-lens-related keratitis. We report the first case occurring in association with extended wear soft contact lenses. Nocardia species can mimic fungal and Acanthamoeba keratitis. Treatment with oral co-trimoxazole has not been previously reported. This case demonstrates a role for co-trimoxazole in treating Nocardia farcinica keratitis based on cultured drug sensitivities.

To report a rare case of bilateral granulomatous chorioretinitis complicated by bilateral peripapillary choroidal neovascular membranes. This is the first reported case in Australia where intravitreal injections of anti-vascular endothelial growth factor ranibizumab were used to successfully treat choroidal neovascular membrane caused by granulomatous chorioretinitis. This is also the first reported case in Australia of Toxocara polymerase chain reaction being performed on intraocular fluids.
