Sound estimates place the number of glaucoma patients with visual field impairment at around 65–80 million worldwide. Accordingly, glaucoma is the world’s second leading cause of blindness. The estimated proportion of undetected glaucoma cases ranges from 50% to 90%, depending on the country. Once glaucoma has been detected, proper ophthalmological care and full compliance with prescribed treatments are crucial factors in keeping the illness at bay. Since glaucoma is irreversible, it is imperative that patients continue therapy in order to curb further progression; namely, impairments to the visual field and loss of visual acuity. Given the disease’s global reach, the initial version of the glaucare app will be available in four languages: German, English, Spanish, and French.
