Summary
Early detection of glaucoma is crucial for preventing blindness. The Stereo Optic Disc Analyser (SODA) software uses 3D imaging to help ophthalmologists diagnose retinal diseases like glaucoma sooner.
Area of Science:
- Ophthalmology
- Medical Imaging
- Software Engineering
Background:
- Glaucoma is a leading cause of irreversible blindness, often asymptomatic in early stages.
- Timely diagnosis is critical for effective treatment and slowing disease progression.
- Current diagnostic methods require enhancement for earlier and more accurate detection.
Purpose of the Study:
- To reengineer and redesign the Stereo Optic Disc Analyser (SODA) software.
- To overcome limitations of the SODA prototype for improved accuracy and usability.
- To develop a commercially viable tool for ophthalmologists to aid in early glaucoma detection.
Main Methods:
- Utilized stereoscopy and 3D image analysis for retinal change detection.
- Applied Software Engineering principles and the software development lifecycle.
- Incorporated object-orientation and usability principles in the redesign process.
Main Results:
- Enhanced accuracy in detecting retinal changes indicative of diseases like glaucoma.
- Improved software usability for ophthalmologists.
- Developed a reengineered SODA package suitable for commercialization.
Conclusions:
- The redesigned SODA software offers a promising tool for early and accurate diagnosis of glaucoma.
- Improved software engineering and design enhance diagnostic capabilities in ophthalmology.
- Commercialization of SODA can lead to wider accessibility for early disease detection.
