Aim: To detect the association between macular pigment optical density (MPOD), which reflects the antioxidant ability of retina, and diabetic retinopathy (DR) and to investigate the correlated factors of MPOD.
Methods: Totally 435 subjects of urban Chinese were recruited to the study and divided into 3 groups: non-diabetes mellitus controls (NDM), diabetic patients without retinopathy (DWR), and patients with early stage of non-proliferative diabetic retinopathy (DR). Demographic and lifestyle characteristics were ascertained by questionnaire.
Aim: To investigate the pattern of diurnal variations of choroidal thickness of macular region of healthyindividuals.
Methods: A prospective study of 32 healthy female subjects was conducted. Each subject underwent 1) a questionnaire on daily schedule, 2) the Pittsburgh Sleep Quality Index questionnaire (PSQI), and 3) ocular examinations including an eye dominance test, fundus photography, and sequential optical coherence tomography (OCT) imaging, on two separate days at five fixed 3h time intervals.
Aim: To measure the macular pigment optical density (MPOD) in healthy Chinese people and patients with early age-related macular degeneration (AMD).
Methods: Cross-sectional population based study. Demographic and lifestyle characteristics were ascertained by questionnaire.
Objective: To understand the perception for the use of cataract surgical services in a population of acceptors and non-acceptors of cataract surgery in urban Beijing.
Methods: From a community-based screening program a total of 158 patients with presenting visual acuity of less than 6/18 on either eye due to age-related cataract were informed about the possibility of surgical treatment. These patients were interviewed and re-examined 36 to 46 months after initial screening.

Objective: To investigate the association of diabetic self-management with the risk of diabetic retinopathy (DR) in patients with type 2 diabetes mellitus.
Methods: Cross-sectional study. Recruited patients with type 2 diabetes mellitus in the Desheng community of urban Beijing between November 2009 and May 2011.
Article Synopsis
- The study aimed to evaluate how well ophthalmologists and community health workers (CHWs) agree on detecting shallow anterior chambers using the oblique flashlight test in a community setting.
- A total of 425 individuals underwent eye examinations conducted by one ophthalmologist and two CHWs (a nurse and a non-professional worker), with their agreement analyzed using the weighted kappa statistic.
- The results showed good agreement among all observers, with kappa values indicating moderate to good alignment, suggesting that trained CHWs can effectively screen for shallow anterior chambers, potentially aiding in blindness prevention in communities.
