Foreword
Article 6.1 of this standard is recommended and the remainder is mandatory.
According to the "People's Republic of China Occupational Disease Prevention Law" to develop this standard. Since the implementation of the standard date, the original standard
GB 11512-1989 inconsistent with this standard, subject to this standard.
In the professional activities, long-term exposure to trinitrotoluene operators can cause changes in the lens lens opacity as the main performance of the
Toxic eye disease, in order to be able to early diagnosis and correct treatment, in order to protect the health of the operator, the development of this standard.
Appendix A to this standard is an informative appendix and Appendix B is a normative appendix.
This standard is proposed and centralized by the Ministry of Health of the People's Republic of China.
This standard is drafted by the Third Hospital of Peking University, China Center for Disease Control and Prevention Occupational Health and Poisoning Control
Add grass.
This standard is interpreted by the Ministry of Health of the People's Republic of China.
Diagnostic criteria of occupational trinitrotoluene cataract
Occupational chronic trinitrotoluene cataract is due to long-term exposure to trinitrotoluene caused by ocular lens opacity
Become the main manifestation of toxic eye diseases.
1 Scope
This standard specifies the diagnostic criteria and principles of occupational trinitrotoluene cataract.
This standard applies to occupational exposure to trinitrotoluene. Clinically met with this standard in the diagnosis and classification standards
Describe the morphological characteristics, and indeed a close contact with trinitrotoluene, according to the principles of this standard for diagnosis and treatment.
2 normative reference documents
The terms of the following documents are hereby incorporated by reference into this standard. Any date that references the date of the document
All subsequent amendments (excluding corrigenda) or revisions do not apply to this standard, however,
The parties to the agreement are able to use the latest version of these documents. Those who do not mind the date of the reference file, its latest
The version applies to this standard.
GBZ 35 diagnostic criteria for occupational cataracts
3 diagnostic principles
According to the close occupational exposure history and the clinical manifestations of changes in lens opacity, combined with the necessary dynamic view
Investigation, referral operating environment survey, comprehensive analysis, excluding other causes caused by lens damage, can be diagnosed.
4 observation object
Have one of the following performance, as the object of observation.
a) thorough inspection, the lens around the circumference of the ring or near the ring point of the shadow;
b) slit lamp microscopy, the lens around the Ministry of cortex scattered in the fine-like cloudy.
5 Diagnostic and grading standards
5.1 a cataract. thorough examination, the lens around the peripheral shadow, but the maximum ring width does not exceed the lens half
One third of the diameter. The ring is made of a plurality of wedge-shaped turbulites, with the wedge facing the periphery, the tip pointing to the center, or the slit lamp
Mirror to see the lens around the aggregation of the majority of the size of the gray-yellow fine-like cloudy, located in the cortex and adult nuclear,
Cortical transparency is reduced. Distribution range with the former.
5.2 two cataracts. peripheral turbidity range than the lens radius of one third, but not more than two-thirds.
Part of the case can be expressed as the central part of the lens appears equal to the size of the pupil diameter complete or incomplete annular turbidity, this mixed
Turbidity is located in the former adult nucleus or anterior cortex.
5.3 three cataracts. the lens peripheral turbidity than the lens radius of more than two-thirds, or the central part of a dense point
Or discoid opacity, visual function (vision and field of vision) are significantly affected.
6 Principles of handling
6.1 Principles of treatment
Refer to GBZ 35 for treatment.
6.2 Other treatments
6.2.1 The subject is reviewed once a year.
6.2.2 Trinitrotoluene cataract diagnosis after the establishment of the principle should be transferred from trinitrotoluene operation; three patients may be appropriate to engage in light
jobs.
7 Correctly use the instructions in this standard
See Appendix A (informative), Appendix B (normative).
Appendix A
(Informative)
Correctly use the instructions in this standard
A.1 The scope of application of this standard
This standard applies only to occupational exposure to trinitrotoluene. Trinitrotoluene cataract lens opacity morphology, color,
Distribution and other obvious characteristics, clinically met with the standard diagnosis and classification criteria described in the morphological characteristics, and
Indeed, the history of close contact with trinitrotoluene can be diagnosed and treated according to the principles of this standard.
A.2 Occupational contraindications See the relevant provisions of the Measures for the Administration of Occupational Health Surveillance. In other causes of cataract,
Such as some drugs caused by lens opacity, early cataracts, etc., should be based on different clinical manifestations and specific circumstances
Analysis, appropriate arrangements.
Appendix B
(Normative appendix)
Eye examination requirements
B.1 vision examination should include far, near vision and correct vision.
B.2 asked the history should pay attention to whether the night blindness.
B.3 routine external eye examination with the new blessing or compound tropicamide eye drops 3 times, to the eyes of the pupil fully dispersed, with direct
Ophthalmoscopy examination of the lens, vitreous and fundus, and finally with the slit lamp microscope to check the lens, record the characteristics of the lesion,
And the lesion is marked in the following format.
