Demyelinating optic neuritis (DON) is an inflammatory demyelinating disease of the central nervous system, which can lead to visual loss in young adults as a major factor. The key points concerned by neuro-ophthalmologists are to reduce the rate of recurrence and improve the prognosis in the course of diagnosis and treatment of DON. Companied with the deep research of diagnostic markers, different classifications and therapies, and evidence-based medicine, there are more and more clinical evidences for the development and standardization of evidence-based guidelines for diagnosis and treatment. According to the routine procedures, the expert steering committee, the guideline development group, the external review expert group and the working group were established. The clinical concerns were collected directly from neuro-ophthalmologists, ophthalmologists of other subspecialties and neurologists. The guideline development group comprehensively searched and systematically evaluated the relevant research evidence at home and abroad, analyzed the preferences and values of patients, and organized the expert consensus meeting. Sixteen recommendations for the diagnosis and treatment of DON were formulated, including classification and diagnosis, therapies in acute and chronic phases, and the follow-up management, which has important guiding significance for the improvement of clinical treatment and reduction of the recurrence rate.

Objective: To master the status of ophthalmic human resource allocation and service delivery at county level in Mainland China, and to provide the basis for strengthening the construction of grassroots ophthalmic personnel team and formulating feasible medium and long-term eye health plans. Methods: All the medical institutions that provided ophthalmic service at county level or above were investigated by online reporting. This study only included medical institutions at county level. Descriptive statistics were used. Results: Three thousand three hundred and fifty-nine medical institutions were included, of which 1 463 hospitals had independent departments of ophthalmology (43.55%). Each medical institution has 3.93 ophthalmologists, 4.59 ophthalmic nurses, 0.30 full-time optometrist and 0.21 full-time optician. Ophthalmologists are mainly undergraduate, and the ratio of senior, intermediate and junior titles is 1.0∶1.7∶1.9. The ophthalmic nurses are mainly graduated from junior colleges or secondary schools, and the ratio of senior, intermediate and junior titles is 1.0∶7.3∶22.3. There were statistically differences in the distribution of job titles of ophthalmologists (χ(2)=106.21, P <0.01) and nurses (χ(2)=128.54, P <0.01) in the eastern, central and western regions. Of each ophthalmologist, the annual number of outpatient, outpatient surgery, inpatient and inpatient operation was 2 377.62, 109.79, 124.03, and 85.97 respectively. Four thousand one hundred and sixty ophthalmologists were able to carry out cataract surgeries independently, accounting for 31.50% of all ophthalmologists. The quantity for annual per capita cataract operation among ophthalmologists who can perform cataract surgery independently was 181.81 per capita. The average beds rate of utilization was 68.91%, and that was less than 60% in 52.99% of medical institutions. Conclusions: Compared with 1998, ophthalmic health personnel at county level in Mainland China has expanded rapidly. But cataract ability of ophthalmologists and the number of cataract surgeries still need to be improved. The structure of ophthalmic nursing staff is irrational. The full-time optometrists and opticians are extremely scarce. It is necessary to cultivate high-quality ophthalmic health personnel and improve beds rate of utilization at county level.

Dry eye is the second most common ocular disease. In China, the incidence rate of dry eye has reached 21% to 30%, and dry eye patients have accounted for more than 30% of the total ophthalmology outpatients. Dry eye has become a common health problem that affects the working efficiency and life quality of Chinese people. Over the past decade, due to the rapid development of diagnostic equipments and new treatments for dry eye, dry eye has become one of the areas with greatest concerns in ophthalmology, and many eye institutions have set up their dry eye clinics. Although the diagnosis and treatment of dry eye has been improved in recent years, the awareness of dry eye in Chinese ophthalmologists is still too simple. In the diagnosis, the interrogation and basic examination are not given enough attention, and we are over-relying on equipments. Clinical examination and instrument operation also have not been standardized. This article emphasizes that we should pay attention to the interrogation, basic examination and standardization of clinical examination and equipment operation in diagnosing dry eye. The treatment regimen should be mostly refined and optimized to be individualized and comprehensive based on the causes, types and severity of dry eye. In addition, the physical and adjuvant therapy of dry eye should be given sufficient attention and applied reasonably. (Chin J Ophthalmol, 2017, 53: 641-644) .
