Insights
High Pass Resolution perimetry is more suitable for children with congenital glaucoma than conventional computerized perimetry. This visual field testing method is faster and more engaging for young patients.
Area of Science:
- Ophthalmology
- Pediatric ophthalmology
- Visual electrophysiology
Background:
- Congenital glaucoma presents unique challenges for visual field testing in young children.
- Accurate visual field assessment is crucial for managing pediatric glaucoma.
- Conventional perimetry methods may be difficult for children to tolerate and perform accurately.
Purpose of the Study:
- To compare the suitability of High Pass Resolution (HPR) perimetry and conventional computerized perimetry (Humphrey 24-2 program) for visual field testing in children under 11 years with congenital glaucoma.
- To determine which perimetric technique offers more reliable and reproducible results in this pediatric population.
Main Methods:
- A cohort of 15 children under 11 years with congenital glaucoma underwent visual field testing.
- Two perimetric methods were employed: Humphrey 24-2 program and HPR perimetry (Ring test).
- Patient tolerance, test duration, and result reproducibility were assessed for both methods.
Main Results:
- High Pass Resolution perimetry demonstrated greater suitability for pediatric patients.
- HPR perimetry had a significantly shorter test duration (5 minutes) and was perceived as a game by 80% of subjects.
- HPR perimetry showed minimal memorization potential, achieving a 68% reproducibility factor, with reliable results in 76% of eyes examined, outperforming the Humphrey test.
Conclusions:
- High Pass Resolution perimetry is a more appropriate and effective method for visual field assessment in children with congenital glaucoma.
- The engaging nature and efficiency of HPR perimetry enhance its utility in pediatric ophthalmology.
- HPR perimetry offers a reliable alternative for evaluating visual fields in young glaucoma patients, improving diagnostic accuracy and patient experience.
Abstract:
Fifteen children aged less than 11 years, affected by congenital glaucoma, underwent visual field testing using two different methods: conventional computerized perimetry (24-2 Humphrey program) and High Pass Resolution perimetry (Ring test). The aim of the study was to discover which of the two perimetric techniques was more suitable for younger patient. Results showed that HPR perimetry is more suitable to children. Reasons include the short duration of the test (5 min), and the appearance like a pleasant game to 80% of the subjects tested. In addition it proved to be better than Humphrey test because of the minimal possibilities of memorisation with a reproducibility factor of 68% in our sample and because of the reliable results and satisfactory evaluation in 76% of the eyes examined.
