Getting Started With #Ophthalmology

A primer on Twitter for ophthalmologists.

Social media has become increasingly integrated into today’s society by providing a rapid and accessible means of exchanging information. Although social media is often used to consume news, keep up with family and friends, and share photos, numerous academic and professional uses have also emerged.

New applications of social media were bound to arise as a result of a constantly expanding user base. According to current estimates, 3.6 billion people worldwide use social media.1 As of July, there were 2.6 billion monthly active users on Facebook, 1 billion monthly active users on Instagram, and 326 million monthly active users on Twitter.2

Within the field of medicine, the use of social media has been steadily increasing, with more medical professional accounts popping up on Facebook, Instagram, Twitter, LinkedIn, and TikTok. The use of Twitter in particular has been widely adopted by physicians and trainees3 and has been especially active in the era of COVID-19, so this article focuses mainly on that platform.


For those who have yet to take the plunge into social media, choosing where and how to begin can be a daunting task. Making an account, however, requires little time or effort and is an easy place to start. When creating a professional social media account, be sure to use your real name and photograph, as this allows other users to recognize and connect with you. Many platforms, including Twitter, also enable users to fill out a profile or description section, which can be used to describe your background, expertise, or interests.

Once your account has been created, you can start connecting with colleagues or organizations. To start building your network, see Twitter Accounts to Follow.


Twitter is a microblogging platform that allows users to share tweets, which are short posts of a maximum 280 characters (although, in the earlier days of Twitter, the limit was 140 characters). Because, ultimately, the goal of Twitter is to share updates with other users, the visibility of a tweet—or how many users will see that tweet—is often considered when crafting a post. User engagement—or how many users will interact with a tweet—is also a consideration.

To maximize visibility and user engagement, Twitter users can include links to other websites and attach images to their tweets. Users can also retweet or share another user’s tweet to their own followers, reply to tweets to initiate conversation with other users, and “like” others’ tweets. Tagging other users in a tweet can also help to garner additional attention and increase user engagement.

The use of hashtags (a clickable keyword preceded by the # symbol) serves as an effective filter and search mechanism to identify relevant posts. Effective tweets may include several applicable hashtags to identify topics of interest, such as #ophthalmology and #eye. One caveat: Some social media experts maintain that the most effective number of hashtags is two per tweet, so be careful not to overdo it.4


Twitter provides a variety of useful applications for medical professionals. Physician users can utilize the platform to connect with colleagues, educate physicians and patients, disseminate research, and communicate at meetings (Figure).5 The use of Twitter has been promoted at events such as the AAO, ASCRS, and ARVO annual meetings, and participants are often encouraged to tweet about talks, share their thoughts, and connect with other attendees.

Figure | An effective tweet may tag other users (eg, @aao_ophth); contain several topical hashtags, including meeting-specific hashtags (eg, #aao2020); and feature a relevant link and/or image for more information. As shown in this tweet, shortening links via Bitly can help users stay within the Twitter-mandated character limit.

Meeting-specific hashtags, such as #aao2020, help users identify content relevant to each event. Attendees can filter through the posts in their feed by clicking on the meeting hashtag. The use of a meeting hashtag also permits those outside the conference to follow the event and interact with participants in a virtual capacity. Further, many ophthalmology conferences, including the AAO, ASCRS, and ARVO annual meetings, often offer workshops and sessions dedicated to discussing social media and its use for professional activities such as practice building, marketing, and networking.

For those interested in public health and patient education, Twitter can be used to share reputable and accurate information on eye health with the public by retweeting or sharing links from the AAO or the National Eye Institute. These organizations also offer social media toolkits to assist users with their public education and eye health awareness efforts.

Ophthalmologists on Twitter can reach broader and new audiences by tweeting about their research. Short posts that summarize the research and include a link to the article can help increase visibility of new data. Publicly sharing research on social media also enables those outside ophthalmology or outside medicine to learn about certain topics. The creation of online journal clubs, which can include trainees, scientists, and physicians on a global scale, can lead to wider discussions and new collaborations. Further, many national and international ophthalmology organizations and journals have social media accounts that they use to share newly published studies before they appear in print. Many journals are also asking study authors for their social media handles to include in the publication.


Social media offers many benefits for physicians, but it is imperative that users across all platforms abide by the laws set forth by Health Insurance Portability and Accountability Act. Although many users post clinical images or case reports to share with colleagues, caution must be exercised when sharing information online, even with patient consent. Additionally, physician users should follow the social media policies set forth by their institution or organization.

Social media offers many creative avenues of communication for ophthalmologists looking to connect with a global audience. These platforms offer opportunities for networking and collaborating on research efforts, and they enable the rapid dissemination of up-to-date information and study findings. The use of social media will only continue to increase across all platforms. For those looking to be a part of the conversation, there is no time like the present to create a Twitter account and join the community on #ophthotwitter.
