Summary
Home online circular contrast perimetry (OCCP) showed comparable baseline results to clinic testing in Asian participants. Long-term home OCCP demonstrated acceptable consistency, though adherence challenges require further support.
Area of Science:
- Ophthalmology
- Medical Technology
- Public Health
Background:
- Traditional visual field testing requires specialized hardware.
- Online circular contrast perimetry (OCCP) offers a hardware-free alternative for visual field assessment on standard devices.
- Home-based perimetry can improve patient access and monitoring frequency.
Purpose of the Study:
- To evaluate the longitudinal performance of home-based OCCP.
- To gather user feedback on home OCCP in an Asian population.
- To compare home OCCP with standard automated perimetry.
Main Methods:
- Twenty glaucoma and fifteen healthy participants performed clinic-based and home-based OCCP.
- Home OCCP was repeated at 3 and 6 months.
- A user-experience survey was administered post-testing.
Main Results:
- Home OCCP showed similar test duration, false negative, and fixation loss rates compared to clinic OCCP.
- A slightly higher false positive rate was observed in home OCCP.
- Bland-Altman analysis revealed good agreement for Mean Deviation, Pattern Standard Deviation, and Visual Index between clinic and home OCCP over 6 months.
Conclusions:
- Home OCCP provides comparable baseline results to in-clinic testing.
- Longitudinal home OCCP demonstrates acceptable consistency for monitoring.
- Patient adherence to at-home monitoring may necessitate additional support strategies.

01:25Glaucoma: Overview
475
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

01:27Open Angle Glaucoma: Treatment
362
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
