In the field of ophthalmology, slit-lamp gonioscopy has long been a cornerstone for examining anterior chamber angles and diagnosing conditions such as angle closure, secondary causes of raised intraocular pressure, neovascularization of angle, angle recession, angle tumors, and foreign bodies. However, the conventional approach for goniophotography is a demanding procedure requiring juggling a gonioscopy lens in one hand and a smartphone in the other. Balancing a gonioscopy lens with one hand makes it difficult to adjust and focus the image in busy clinical settings. This article introduces a groundbreaking solution to this problem - a universal slit-lamp-mounted gonioscope ingeniously repurposed from discarded materials, that is, indirect goniophotography (IndiGo). This novel system simplifies the process of both gonioscopy and goniophotography, allowing ophthalmologists to easily assess anterior chamber angles and capture high-quality images. These images can be swiftly shared with glaucoma specialists worldwide for digital analysis. Not only does this approach enhance examination efficiency, but also it fosters sustainability in ophthalmic diagnostics.
