Abstract
Concepts pertaining to ophthalmology have lots of theoretical frameworks. Neophyte residents and novice surgeons may have to mentally visualize these concepts during the initial days of training. Only a powerful cognitive tool such as a three-dimensional (3D) eyeball model, with real-time TrueColor confocal images (and not animated images or models), can fill in these intellective mental gaps. Giving the users (i.e., residents and students) the power to choose and visualize various parts of the eye, with multiple magnitudes of zoom, is mandatory for optimal e-learning. To make ophthalmic concept learning better, we have developed a 3D app Eye MG 3D (patent pending) comprising ocular anatomy and pathophysiological 3D models, built on an advanced interactive 3D touch interface, by using patient's real-time confocal images to serve as a new-age pedagogical tool and e-counseling. According to our knowledge, there are no applications to date that incorporate real-time high-resolution multimodal confocal fundus images and photoreal visuals for interactive and immersive 3D learning.

According to our knowledge, there are no applications to date that incorporate real-time high-resolution multimodal confocal fundus images and photoreal visuals for interactive and immersive 3D learning.
Throughout the last decade, several innovative and interactive smartphone applications became useful learning resources for ophthalmologists.[123] They teach anatomy, clinical ophthalmology, mnemonics, grading systems, and surgical skills.[4] However, in most of the anatomy teaching apps, the images used are 2D animated images or 3D animated models, which are quite different from the real-time images that one encounters in clinical practice. Moreover, there are very few zoom sections of complex, important landmark structures such as the angle of the anterior chamber in those teaching applications. Thus, we have developed a 3D application named “Eye MG 3D” (patent pending) to simplify ophthalmic concept learning [Fig. 1] for studying ocular anatomy and pathophysiology, built on an advanced interactive 3D touch interface, by using patient’s real-time confocal fundus images along with their multimodal images in multiple sections. We have also constructed the application with varying levels of zoom, ranging from a gonioscopic view to electron microscopic view, for complex structures such as the angle of the eye [Fig. 2]. This novel app aims to serve as a new-age 3D pedagogical and e-counseling tool for ophthalmic learning and counseling, respectively.

Innovation
Usage of truecolor confocal real-time images to construct 3D models
The real-time gonioscopic images and the 110-degree mosaic real-time TrueColor confocal fundus images of various normal and pathological eyes were used for coding to build an advanced interactive 3D touch interface model. The highlight feature of this Eye MG 3D app is as follows: for every normal and pathological fundus, with a simple click of a button, various multimodal real-time images such as autofluorescence and infrared imaging can be visualized three-dimensionally. The various parts of each eyeball model with multimodal imaging were coded in the Unreal Engine software for customized sectional viewing and zoom of choice of the viewer in 360-degree angles [Fig. 3].

Discussion
Pedagogical transformation
This pedagogical transformation in e-ophthalmology aims to reinvent the approach to ophthalmic teaching through virtual platforms.[5] This 3D app is constructed with pioneering ways of cult teaching, which can be extended out to any video output device [Fig. 1], along with photoreal cinematic 3D learning in ophthalmology. Multimodal confocal real-time imaging and ultra-zoom features in an e-learning app with deep visualization experiences have never been reported in the literature and can pave the way for a new age in ophthalmic pedagogy.
e-Counseling stations
Eye MG 3D will not only benefit the residents and ophthalmologists but will also help in customized patient counseling. This application is also constructed in a patient-friendly format. Thus, the nature of the disease and procedures ranging from a simple YAG laser peripheral iridotomy or anti-VEGF injection to a complex trabeculectomy/retinal surgery can be counseled with this app [Fig. 9]. The complex structures such as the angle of the anterior chamber, ciliary body, and posterior segment of the eye are constructed with 3D photoreal visuals of real-time images for simple and effective patient counseling experiences.[67]

Prerequisites of the Eye MG 3D App and its availability in various platforms
This app is currently available free of cost from Google Play Store for Android phones that run Android 7.0 or above. Users can either download the app from Google Play Store or directly scan the QR code [Fig. 10].[8] Detailed ocular structures and pathologies related to ophthalmology are being added periodically (once every 4 weeks) as updates for comprehensive ophthalmic pedagogy and counseling. We are also working on more add-on features (such as real-time clinical 3D videos) for the Eye MG 3D app, which will be made available to the users.
Figure 10
Image showing the “Eye MG 3D” app available in Google Play Store and the QR code for downloading the app for Android users
According to our knowledge, we tested the Eye MG 3D app on various Android phones, and there seems to be no issue regarding the processing power, touch screen, or sensor. It is also very user-friendly. For iOS, this app is available from the App Store as “Eye MG Max”, which is an upgraded version with technical variations. It is also possible to run this on a Windows computer instead of a smartphone. You can access the Windows version of the app from the website (meh.org.in). On the website, hover over the “RESEARCH & DEVELOPMENT” tab and choose the “Eye MG App” option. Then, click the icon [Fig. 11] to download the zip file and install the application on your PC/laptop that supports Windows. The Windows version of the app is also provided free of cost.

Conclusion
Carving a mobile application for neophytes for pedagogy and patients for counseling with 3D real-time confocal images will allow them not to have any dark side regarding the anatomy and pathology of oculus uterque (OU). According to our knowledge, there is no application to date that incorporates real-time high-resolution confocal multimodal images for interactive 3D learning. Thus, we developed the 3D application named “Eye MG 3D” for immersive pedagogy and e-patient counseling.
