This issue focuses on the research progress of ophthalmic epidemiological investigation. The responsible editorial committee responsible for the planning, composition and review of the key contents of this issue is Professor He Mingguang.

Field epidemiological research is different from clinical patient-based disease diagnosis and research, mainly manifested by the following characteristics: First, the diagnosis of diseases can usually only rely on one-time examination, and cannot be confirmed through follow-up and follow-up visits; Second, due to the limitations of field research conditions, only relatively simple inspection equipment can be used for diagnosis; Third, on-site investigation usually involves multiple inspectors to jointly complete the inspection of the subject, which requires a standardized and repeatable inspection method; Fourth, there is a need for horizontal comparisons of studies in different regions and even different ethnicities, and standardized diagnostic criteria and examination methods are needed.

Chinese names for partial retinal lesions, such as aneurism (aneurysm) and telegiectasia, are not accurate enough, although they have been used for many years.

Leiomyoma is a benign tumor that originates from smooth muscle cells and occurs in the gastrointestinal tract and uterus. Intraocular leiomyoma is rare, mainly in the ciliary body and anterior choroid, and extremely rare in the posterior choroid. It is difficult to distinguish from choroidal melanoma and choroidal metastatic cancer. A case of posterior choroidal leiomyoma admitted to Beijing Tongren Eye Center is reported as follows:

posterior polymorphous corneal dystrophy (PPCD) is a hereditary eye disease that mainly involves the corneal endothelium and posterior elastic layer. It has no clinical symptoms in the early stage and is often discovered accidentally during eye examination. On September 29, 2015, the author admitted a patient with PPCD with increased intraocular pressure and glaucomatous optic nerve damage in the fundus as the first symptom. The report is as follows.

The patient was a 47-year-old male. He went to the Department of Ophthalmology of Dushanzi People's Hospital in Xinjiang because of decreased visual acuity and deformed vision in his left eye for 2 months. Two months ago, the vision of the left eye decreased and the vision was deformed. He was diagnosed as "fundus hemorrhage" in an outside hospital. He was given hemostasis and other drugs, but the symptoms did not improve. Physical health in the past, and no abnormalities were found in the general examination. Eye examination: visual acuity was 1.2 in the right eye and 0.3 in the left eye (uncorrectable). No abnormalities were observed in the anterior segment of both eyes. For fundus examination, seeQuintessence Picture 1。 For FFA inspection, seeQuintessence Picture 2。 Automatic visual field examination showed a dark spot in the center of the left eye and normal in the right eye. Clinical diagnosis: vascular streaks in both fundus; Choroidal neovascularization of the left eye.
