Purpose Social media has become a popular source of health information for patients. This study aimed to characterize the top-performing ophthalmologic posts on a large social media platform to better understand the spread of ophthalmic information via social media. Materials and Methods This was a web-based study that searched for ophthalmology-related posts on Instagram, with subjects being users who posted ophthalmic content. A list of 36 ophthalmology-related hashtags, including the most common diagnoses and procedures identified from the IRIS Registry, was queried. For each hashtag, data were collected for “Top 9 posts” (as ranked by Instagram’s engagement-based algorithm) at three different time points. Posts were analyzed for the poster’s background, credentials, post format, content, caption length, and engagement level. Results Of the top-performing posts analyzed (n = 972), the most frequent post format was a photo (82.2%), followed by video (8.8%) and graphic (8.4%). Ophthalmologists (35.8%) authored the highest number of posts, followed by patients (27.1%), optometrists (20.1%), and organizations (12.7%). The highest average engagement level ratios (ELRs) belonged to ophthalmologists-in-training (0.096), followed by patients (0.084), optometrists (0.070), all ophthalmologists (0.067) and organizations (0.051); p < 0.001. The most engaging type of content was self-promotional (0.118) and personal experience-related (0.091); educational content was the least engaging (0.059) even though it comprised the majority of posts (56%); (p < 0.001). Characteristics that predicted the highest ELRs (reaching 80th percentile) were captions and/or images that featured personal experiences (3.335 OR), whitecoats (3.259), and those authored by ophthalmologist trainees (3.172); (p < 0.01). The least engaging were those featuring fundus photos (0.281), educational content (0.359), and authored by organizations (0.428); (p < 0.05). Conclusion The majority of ophthalmologic content on Instagram is authored by non-ophthalmologists, with educational content being the least engaging. Practicing ophthalmologists have an opportunity to reach more patients through social media by incorporating specific features known to drive post engagement and reach. Precis Social media has become a popular source of health information for patients. Our study demonstrates that the majority of ophthalmology content on Instagram is authored by non- ophthalmologists, with educational content being the least engaging. Practicing ophthalmologists have an opportunity to reach a wider audience through social media by incorporating specific features known to drive post engagement and reach.

We have identified four pre-operative variables that predicted a longer duration of surgery. Preliminary results suggest a positive correlation between this scoring system and duration of surgery. An adequately powered prospective multi-centre study is needed to validate our findings.

Purpose This study aims to describe the role of knowledge diffusion in evolving governance principles for Islamic banking. Design/methodology/approach This study develops a discursive theoretical debate using the discourse analysis method on the Sharīʿah principles related to interest (Riba), excessive uncertainty (Gharrar) and profit and loss sharing and their convergence with the conventional banking principles of profitability, solvency and liquidity. Findings The study proposes a novel framework that describes how knowledge diffusion bridge-up the Sharīʿah and banking principles in terms of integration of banking principles by Sharīʿah scholars, integration of Sharīʿah principles by managers and the resultant, emergent principles for the governance of Islamic banking. Practical implications The proposed framework can inform professionals on how knowledge of banking practices and Sharīʿah can help them in governing Islamic banking. The Board of Directors may adopt a holistic approach for encouraging enhanced interactions between Sharīʿah scholars and managers. Such interaction may be increasing harmony, reducing conflicts and better coordination resulting in Sharīʿah-compliant and market wise viable products and services, thus increasing banking profitability. Originality/value This is the first study, which acknowledges and illustrates the role of the knowledge diffusion process in evolving governance principles for Islamic banks. This paper contributes to the theory of corporate governance by using the knowledge, aptitude and practice theory lens to examine conceptually how Islamic banking governance principles emerged through the knowledge diffusion process.

The best treatment option in ankle arthritis have always been debated. It is either ankle arthroplasty or arthrodesis. The incidence of ankle arthritishas increased over the recent decades due to the increasing life span of the population and incidence of injuries sustained during sporting events. Although arthrodesis is still largely regarded as the gold standard for it is a safe procedure but in long term, several studies have reported complications such as arthritis in adjacent joints, hip dysfunction and knee problems. Currently results have shown that ankle arthroplasty offers a better long term results than arthrodesis especially in view of patient's satisfaction and its good functional outcome. This review article aims to analyse both options and their respective outcomes.
