Abstract
The utility model provides a can install the ophthalmology RAPD quantitative measurement board of neutral density filter, its characteristic includes protruding screw and neutral density filter on light tight plastic slab, the plastic slab, offers the equipment that neural eye doctor is used for spreading into into obstacle (RAPD) quantitative measurement with the relativity pupil, integrates the neutral density filter of every different density on an ophthalmology RAPD quantitative measurement board. Which is convenient for clinical operation.
Description
Technical field
This utility model relates to armarium auxiliary examination design field, for neuroretinal rim area (
RAPD
) neuro-ophthalmic disease examination equipment.
Background technology
Inspection is the important Examined effect of neuro-ophthalmic.The most domestic for
RAPD
The instrument of quantitative measurement is single photography neutral density filter.Practical operation occurs measure inconvenience, it is not easy to contrast, exchange the shortcomings such as filter inconvenience for.
Summary of the invention
For above-mentioned clinical examination produced problem, the design purpose is: be supplied to neuro-ophthalmic doctor for neuroretinal rim area (
RAPD
) equipment of quantitative measurement, the neutral density filter of each different densities is integrated in one and measures on plate.It is easy to clinical manipulation.By ophthalmology
RAPD
In quantitative measurement plate different neutral density filters be respectively placed in simple eye before, by pocket lamp swing test, it is thus achieved that detection by quantitative result.
RAPD
Quantitative measurement plate is commonly used neutral density filter density and is respectively
