A case study of a patient who suffered from chronic daily headaches is presented in which use of contoured prism technology reduced the patient’s symptoms and use of medication. More studies are warranted to investigate these results further.
Ground-in prism and lens decentration are routinely utilized by optometrists and ophthalmologists to relieve symptoms of trigeminal dysphoria.1 This case study follows a symptomatic adult Caucasian male over 90 days to determine the effects of contoured prism technology on debilitating chronic daily headaches, using a validated Headache Impact Test (HIT-6).
Qualitative data analysis reveals that full-time wear of neurolenses, prescription spectacle lenses that add a contoured prism to bring the eyes into alignment, significantly improved patient HIT-6 score by 3.5 lifestyle changes.2 Notably, headaches that were frustrating and tiring enough to prevent activities of the patient’s daily living on a highly frequent basis were completely alleviated by Day 90.
Furthermore, there was subjective improvement of patient intake frequency of Advil (ibuprofen) and Excedrin (acetaminophen-aspirin-caffeine) as the patient was able to decrease intake from “daily” to “on very rare occasion.” Additionally, the case study patient was able to discontinue butalbital-acetaminophen-caffeine (50:325:40 mg) as well as amitriptyline previously prescribed by his neurologist.
Although a broader study is warranted, this case study suggests that adult patients suffering from chronic headaches significantly benefit from the addition of neurolenses, with contoured prism technology, to their medical regimen.
