Objective Despite advances in ocular and orbital imaging, instrumentation, materials, and surgical procedures, the management of open globe injuries continues to pose difficult management dilemmas. In this retrospective study, we identify clinical characteristics and outcome of a series of open globe injuries presenting to a major UK centre. Method Operating department records were reviewed to identify all patients who had undergone repair of an open globe injury from 1 January 1998 to 1 January 2003 at the Manchester Royal Eye Hospital. Case notes were examined to determine demographic data, mechanisms of injury, influence of alcohol/drugs, and location of injury. The Snellen visual acuity on presentation and initial clinical signs were recorded. Results In total, 115 cases of open globe injury were identified of which 107 cases notes were available for review. Injury to the eye with a sharp object accounted for 71/107 (66%) cases and blunt mechanisms for 30/107 (28%) cases. In six (6%) cases the cause of injury was unknown. The rate of secondary enucleation in our series of 107 open globe injuries was 13/107 (12%). Significant risk factors on presentation associated with eventual enucleation included relative afferent pupillary defect (Po0.001), absence of a red reflex (Po0.001), presence of a lid laceration (Po0.02), a blunt mechanism of injury (Po0.02), and an initial VA worse than 6/60 (P ¼ 0.03). Conclusion From this retrospective study, we have identified several factors that may aid the clinician in deciding on the prognostic value of primary repair. Blunt injuries associated with adnexal trauma, with poor initial visual acuity, the presence of an RAPD or retinal detachment, and the absence of a red reflex are associated with a significantly higher rate of subsequent enucleation.

Phacovitrectomy for macular hole surgery without postoperative face down posture is a reasonable approach, as long as the eye has more than 70% gas fill (beyond the inferior retinal vascular arcade) on the first postoperative day. This study showed no statistically significant difference between patients who postured and those who did not posture. The combination of phacoemulsification, pars plana vitrectomy, internal limiting membrane, and gas tamponade in macular hole surgery reduces the difficulty of posturing in elderly patients. This technique saves the patient from exposure to a second intraocular intervention to remove a cataract which will commonly develop after vitrectomy and gas tamponade alone.

Background The WHO's Vision 2020 global initiative against blindness, launched in 2000, prioritises children. Progress has been hampered by the global paucity of epidemiological data about childhood visual disability. The British Childhood Visual Impairment and Blindness Study 2 (BCVIS2) was undertaken to address this evidence gap. Methods UK-wide prospective population-based observational study of all those aged under 18 years newly diagnosed with visual impairment or blindness between Oct 1, 2015 and Nov 1 2016. Eligible children were notified simultaneously but independently by their managing ophthalmologists and paediatricians via the two national active surveillance schemes, the British Ophthalmic and Paediatric Surveillance Units. Standardised detailed data were collected at diagnosis and one year later. Incidence estimates and relative rates by key sociodemographic factors were calculated. Descriptive analyses were undertaken of underlying ophthalmic disorders and nonophthalmic comorbidities. FindingsOf 784 cases, 72% had additional non-ophthalmic impairments/disorders and 4% died within the year. Annual incidence was highest in the first year of life, 5•2 per 10,000 (95% CI 4•7-5•7) with cumulative incidence by 18 years of 10•0 per 10,000 (95% CI 9•4 to 10•8). Rates were higher for those from any ethnic minority group, the lowest quintile of socio-economic status, born preterm or with low birthweight. Only 44% had a single ophthalmic condition: disorders of the brain/visual pathways affected 48% overall. Prenatal or perinatal aetiological factors accounted for 84% of all conditions. InterpretationBCVIS2 provides a contemporary snapshot of the heterogeneity, multi-morbidity and vulnerability associated with childhood visual disability in a high income country, and the arising complex needs. These findings will facilitate developing and delivering healthcare and planning interventional research. They highlight the importance of including childhood visual disability as a sentinel event and metric in global child health initiatives.

Background: Orbital exenteration is a rare, but disfiguring procedure reserved for the treatment of locally invasive malignancy or potentially life threatening orbital neoplasms, when less destructive techniques are inadequate. The authors report their experience and analyses of 64 cases of orbital exenteration performed over a 13 year period, looking specifically at key factors affecting mortality associated with such a destructive surgical procedure. Methods: Records were reviewed retrospectively of all patients who had undergone exenteration of the orbit from 1 January 1991 to 1 April 2004 inclusive, at the Manchester Royal Eye Hospital. In all cases of deceased individuals, the cause of death was determined by liaison with the general practitioner and local health authority. Duplicate death certificates were requested for all deceased patients from the Registrar for Births, Deaths, and Marriages, Southport, UK. Kaplan-Meier analysis was used to estimate survival following exenteration. Results: Overall, 1 year survival post-exenteration was high at 93%. After 3 years this had fallen to 67%, followed by 57% after 5 years, and 37% at 10 years. 13 patients died as a direct result of the orbital tumour. A further nine died of unrelated medical conditions, and two patients succumbed to malignant processes originating elsewhere in the body. There was no difference in survival rate at 3 years (p = 0.99) and 5 years (p = 0.454) between those with clear resection margins and those without. Conclusion: In this study it was found that there was an overall mortality rate of 38% over 12 years. The presence of clear surgical margins, although reassuring for the surgeon, should not be regarded as an indication of cure. However, an overall 1 year survival of 93% and a 10 year survival of 37% are reassuring in that a proportion of individuals achieve surgical cure following exenteration. 38% of patients died as a result of other medical causes over the 12 year follow up.
