Grand Challenges in global eye health: a global prioritisation process using Delphi method
Background: We undertook a Grand Challenges in Global Eye Health prioritisation exercise to identify the key issues that must be addressed to improve eye health in the context of an ageing population, to eliminate persistent inequities in health-care access, and to mitigate widespread resource limitations. Methods: Drawing on methods used in previous Grand Challenges studies, we used a multi-step recruitment strategy to assemble a diverse panel of individuals from a range of disciplines relevant to global eye health from all regions globally to participate in a three-round, online, Delphi-like, prioritisation process to nominate and rank challenges in global eye health. Through this process, we developed both global and regional priority lists. Findings: Between Sept 1 and Dec 12, 2019, 470 individuals complete round 1 of the process, of whom 336 completed all three rounds (round 2 between Feb 26 and March 18, 2020, and round 3 between April 2 and April 25, 2020) 156 (46%) of 336 were women, 180 (54%) were men. The proportion of participants who worked in each region ranged from 104 (31%) in sub-Saharan Africa to 21 (6%) in central Europe, eastern Europe, and in central Asia. Of 85 unique challenges identified after round 1, 16 challenges were prioritised at the global level; six focused on detection and treatment of conditions (cataract, refractive error, glaucoma, diabetic retinopathy, services for children and screening for early detection), two focused on addressing shortages in human resource capacity, five on other health service and policy factors (including strengthening policies, integration, health information systems, and budget allocation), and three on improving access to care and promoting equity. Interpretation: This list of Grand Challenges serves as a starting point for immediate action by funders to guide investment in research and innovation in eye health. It challenges researchers, clinicians, and policy makers to build collaborations to address specific challenges.

Grand Challenges in global eye health: a global prioritisation process using Delphi method
Background
We undertook a Grand Challenges in Global Eye Health prioritisation exercise to identify the key issues that must be addressed to improve eye health in the context of an ageing population, to eliminate persistent inequities in health-care access, and to mitigate widespread resource limitations.
Methods
Drawing on methods used in previous Grand Challenges studies, we used a multi-step recruitment strategy to assemble a diverse panel of individuals from a range of disciplines relevant to global eye health from all regions globally to participate in a three-round, online, Delphi-like, prioritisation process to nominate and rank challenges in global eye health. Through this process, we developed both global and regional priority lists.
Findings
Between Sept 1 and Dec 12, 2019, 470 individuals complete round 1 of the process, of whom 336 completed all three rounds (round 2 between Feb 26 and March 18, 2020, and round 3 between April 2 and April 25, 2020) 156 (46%) of 336 were women, 180 (54%) were men.

A Review of the Cytokine IL-17 in Ocular Surface and Corneal Disease
AIM: To investigate the role of interleukin-17 in ocular surface and corneal disease. Ocular surface and corneal disease is a leading cause of blindness and is an ongoing challenge for the public health sector to implement effective therapies. The majority of cells in corneal lesions are derived primarily from neutrophils that induce inflammatory events that lead to tissue damage. One of the key pro-inflammatory cytokines is IL-17, and it has been investigated in order to facilitate the understanding of the pathogenesis of ocular surface lesion development. METHOD: A review of the literature was performed through a systematic approach. RESULTS: IL-17 has been shown to exacerbate dry eye disease, viral and bacterial keratitis lesion severity, although it was found to be protective for Acanthamoeba. Antibodies developed to neutralize IL-17 have shown some promise in reducing the severity of some diseases. CONCLUSION: IL-17 plays a role in the pathogenesis of ocular surface and corneal disease and targeting this cytokine may provide a useful treatment option in the future
Investigation of attributes which guide choice in cataract surgery services in urban Sydney, Australia.
BACKGROUND: It is critical to consult patients to develop patient-centred cataract surgery care. We aimed to identify attributes patients consider when making decisions about cataract surgery in an Australian context, where both publicly and privately funded surgery are available. This is the first step in investigating how decisions are made about cataract surgery services. METHODS: This observational qualitative study was undertaken in two public hospitals and one private practice in Sydney, Australia. The study involved 19 women and men with age-related cataracts and no previous cataract surgery, aged > 18 years, able to speak conversational English or Mandarin. A multi-stage attribute development process was followed, including: literature review, semi-structured interviews with surgery candidates in three eye clinics, and review by an expert panel. The main outcome measures were primary attributes for making choices about cataract surgery. RESULTS: Wait time, cost, institutional reputation, surgeon experience and travel time were identified as principal attributes; lower value was placed on consultation length and accessibility. Non-English speaking participants indicated greater interest in pre-operative information than English speakers, but expressed trust in the Australian healthcare system. CONCLUSIONS: Findings suggest individuals prioritise attributes which consume time or incur costs when accessing care (wait time, cost and travel time). They also consider factors associated with the outcome of their cataract surgery (surgeon experience and institutional reputation). Similar to other decision-making processes, patients are likely to trade between these different attributes depending on their personal preferences and circumstances
