It\u2019s something he\u2019s been dealing with for nearly 30 years.<\/p>\n<p>Known as the \u201csilent thief of sight,\u201d glaucoma causes pressure to gradually build<br \/>\n                     in the eye. It rarely feels urgent, and like Storms, many patients don\u2019t see a doctor<br \/>\n                     until their vision loss has progressed significantly.<\/p>\n<p>As his vision continued to get hazier into adulthood, Storms was prescribed eye drops<br \/>\n                     that he used for the following 10 years. But the drops were not enough. At follow-up<br \/>\n                     visits, his eye pressure continued to rise, and he was told he would need surgery<br \/>\n                     to prevent vision loss. \u00a0<\/p>\n<p>USF Health ophthalmologist <a href=\"https:\/\/www.getcare.health.usf.edu\/providers\/ramesh-ayyala-1356395404\" rel=\"nofollow noopener\" target=\"_blank\">Dr. Ramesh S. Ayyala<\/a> saved Storms\u2019 vision and relieved the pressure by placing stents in both eyes.\u00a0<\/p>\n<p>Five years later, Ayyala continues to monitor Storms\u2019 condition every three months.\u00a0<\/p>\n<p>While the surgery preserved Storms\u2019 vision, managing glaucoma remains a lifelong process.<\/p>\n<p>Monitoring changes in vision associated with glaucoma requires constant vigilance,<br \/>\n                     with regular appointments and testing that can be time-consuming, costly and difficult<br \/>\n                     for patients to maintain.<\/p>\n<p>\u201cPatients have to come to us for regular testing, using expensive equipment in specialized<br \/>\n                     clinics and many simply don\u2019t come often enough,\u201d said Ayyala, the James P. and Heather<br \/>\n                     Gills Endowed Chair and chair of the Department of Ophthalmology in the USF Health<br \/>\n                     Morsani College of Medicine.<\/p>\n<p>That challenge inspired Ayyala and his colleagues at the University of South Florida<br \/>\n                     to rethink how, and where, glaucoma is detected.<\/p>\n<p>He is leading a study of GlaucTest, an investigational AI-powered app that allows<br \/>\n                     patients to perform visual field testing at home using their own smartphone, a low-cost<br \/>\n                     virtual reality headset and a handheld clicker.<\/p>\n<p>Currently in the research stage, Ayyala\u2019s goal is to replicate the gold-standard Humphrey<br \/>\n                     Visual Field Analyzer found in clinics. Ayyala hopes the technology could transform<br \/>\n                     the test that typically costs $30,000 in equipment into an at-home experience for<br \/>\n                     about $42. After the patient performs the five-minute test per eye, results are securely<br \/>\n                     uploaded for their ophthalmologist\u2019s review.<\/p>\n<p>                     <img decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/us-fl\/wp-content\/uploads\/2026\/06\/ayyala-machine.jpg\" alt=\"Patient is examined at machine\"\/><\/p>\n<p class=\"media-caption\">Traditional glaucoma exams are conducted using the Humphrey Visual Field Analyzer<br \/>\n                           [Photo by Frederick Coleman, USF Health]<\/p>\n<p>                     <img decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/us-fl\/wp-content\/uploads\/2026\/06\/ayyala-glasses.jpg\" alt=\"Patient wears VR glasses\"\/><\/p>\n<p class=\"media-caption\">The patent-pending GlaucTest is designed for at-home use\u00a0 [Photo by Frederick Coleman,<br \/>\n                           USF Health]\u00a0<\/p>\n<p>                     <img decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/us-fl\/wp-content\/uploads\/2026\/06\/ayyala-phone.jpg\" alt=\"Phone demonstrates GlaucTest\"\/><\/p>\n<p class=\"media-caption\">Paired with a virtual reality headset, the AI-powered app runs on the patient\u2019s smartphone<br \/>\n                           [Photo by Frederick Coleman, USF Health]\u00a0<\/p>\n<p>\u201cWe want to use technology to move to a place where physicians monitor patients remotely<br \/>\n                     while they test themselves at home,\u201d Ayyala explained. \u201cThe goal is to give the power<br \/>\n                     to the patient, the best way to manage chronic diseases like glaucoma.\u201d \u00a0<\/p>\n<p>For Storms, the technology represents more than convenience.
