In this report, the authors highlight 2 effective and simple techniques of video documentation of the anterior chamber angle using the newer generation iPhone, iPhone 11 Pro Max. In these techniques, we also used a commercially available macro lens with the phone. The patient positions his/her chin on a slit-lamp biomicroscope as done during a routine slit-lamp examination. The first observer places the gonioscope over the patient's eye and projects a thin slit beam of light of the slit-lamp biomicroscope along the superior or inferior Gonio mirror. A second observer records the anterior chamber angle findings using the macro lens clipped smartphone after bringing it closer to the eye of the patient. In the phone, the video mode is selected after opening the phone's camera application. In the subcategory of video mode, 1× or the wide-angle mode is chosen. Under 1× mode, the magnification is further increased to 3× to document high-quality imaging findings of angle. Similarly, in the second technique, the slit (streak) light beam of the direct ophthalmoscope was used that completely circumvented the need for a slit lamp as a source of light.
