1989165438+10 to1993 65438+February, as a visiting scholar, engaged in the research of ophthalmology epidemiology and glaucoma in the Doheny Eye Institute of the University of Southern California and the National Eye Institute of the United States, and made some achievements in the relationship between cataract and nutrition and the retinal choroidal circulation of glaucoma.
The basic knowledge and theory of ophthalmology are solid, and they can grasp the present situation and development trend of ophthalmology at home and abroad, and can absorb new knowledge and scientific and technological achievements of ophthalmology and apply them to practical work. It can independently handle all kinds of difficult ophthalmic diseases and complicated intraocular and extraocular operations, such as difficult filtering screen resection, extracapsular cataract extraction and intraocular lens implantation, complicated retinal detachment surgery, etc., and has achieved good results.
Since 1978, he has been engaged in the clinical and research work of glaucoma and has rich experience in the prevention and treatment of glaucoma. I deeply studied the pathogenesis of primary angle-closure glaucoma, and put forward early diagnosis methods, so that a group of patients without clinical symptoms were diagnosed and treated in time, and the diagnosis rate and cure rate were improved. To study the changes of optic papilla in glaucoma and improve the diagnostic level of primary open angle glaucoma. For refractory advanced glaucoma, the surgical method was improved and good results were achieved.
In ophthalmology, the determination method of tear film rupture time was established for the first time, and the indicators for diagnosing keratoconjunctivitis sicca and conjunctivitis in China were put forward, which made a lot of work for the research and clinic of Sjogren's syndrome in our hospital.
In addition to doing a good job in ophthalmology and glaucoma research, he also actively engaged in the epidemiological research of eye diseases, and successively participated in six Chinese-foreign cooperative scientific research works, including the Epidemiological Investigation of Eye Diseases in Shunyi County, Beijing, the Study of Eye Diseases in Tibet and the Study of Cataract in Linxian County, Henan Province, which provided scientific basis for solving the occurrence of eye diseases and preventing blindness in China.
