Serving patients across the Rockville, Maryland region, Dr. Anthony Roberts performs Lasik surgical procedures and utilizes a personalized approach to eye and vision care. To this end, Dr. Anthony Roberts’ team at Shady Grove Ophthalmology conduct glaucoma exams using advanced technologies such as the Humphrey Field Analyzer (HFA). Eye care providers use HFAs to perform a visual field test that helps detect peripheral and central vision issues, which can manifest as a result of glaucoma, brain tumors, strokes, or neurological deficits. Field of vision testing supplements optic nerve examinations, intraocular pressure measurements, and other procedures involved with glaucoma diagnosis and care, making it an important tool for treating the condition. During a HFA exam, an ophthalmologist asks the patient to focus on a central target directly ahead of them and uses the analyzer to present a point of light. The patient presses a button when the light comes into their peripheral vision. After statistically analyzing the responses and comparing them against the normal baseline, the HFA generates a detailed printout that outlines the patient’s visual field and enables the ophthalmologist to identify peripheral vision blind spots.
