Exfoliation glaucoma is a category of glaucoma secondary to exfoliation syndrome, which is rarely encountered in clinical practice. We reported 2 cases with deposits of white material on the pupillary border of the iris. Opacity band could be observed surrounding the anterior lens capsule after pupil dilation, and the Sampaolesi line was seen under gonioscope. Understanding the clinical characteristics contribute to improving the diagnosis and treatment of exfoliation glaucoma.

Objective: To explore the main nursing problems and demands of patients with severe visual impairment or blindness, so as to provide the basis for health staff to formulate home care support plans of high quality. Methods: By using a descriptive qualitative method, face-to-face semi-structured interviews were conducted among 20 patients with severe visual impairment or blindness who were hospitalized in the top-grade ophthalmic hospital in Guangzhou from April to September 2020. The inductive content analysis method was used to analyze the data. Results: The main nursing problems of these patients were the lack of self-care ability, limited social activities, and difficulty in adapting to changes in family roles. Nursing needs include the hope that hospitals can provide multidimensional disease-related knowledge and multi-channel medical consulting services. Conclusion: Patients with severe visual impairment or blindness have many problems and needs in home care. They would like to obtain multi-dimensional knowledge and receive multi-channel medical consultation. Health staff from hospitals and communities should attach great importance to these patients, as well as provide appropriate guidance and assistance, so as to improve their activities of daily living.

Objective: To investigate and analyze the prevalence of dry eyes in Zhengzhou office workers, and identify the related risk factors in order to provide evidence for effective prevention and treatment. Methods: We selected 873 cases of Zhengzhou office workers who had checkup in our hospital from September 2019 to September 2020 as the research subjects. They were investigated with self-designed general information questionnaire and OCULUS Jenvis-OSDI dry eye questionnaire and scores of the questionnaires will be assessed. At the same time,they underwent dry-eye-related inspections such as slit lamp examination, corneal fluorescein staining score (FL), Schimier I test (SIT) and tear break-up time (BUT) assessment. The prevalence and risk factors of dry eyes in these office workers were statistically analyzed. Results: Among 873 Zhengzhou office workers, 360 cases were diagnosed as dry eyes, and the total prevalence of dry eye was 41.24%. The female prevalence rate was 44.62%, which was significantly higher than that of male (36.26%, P=0.014). OSDI scores and FL scores were positively correlation as well as BUT and SIT, while OSDI (and FL) and BUT (and SIT) were negatively correlation. Logistic multivariate analysis showed that dry eyes family history, menopause, ocular surgery history, eye drops using, long time corneal contact lenses wearing, long time video terminal operating, lack of sleep and diabetes history were independent risk factors in office workers’ dry eye disease (all P<0.05), while drinking was protective factor (P=0.001). Conclusion: The dry eyes prevalence is high among office workers. The risk factors include dry eye family history, menopause, ocular surgery history, eye drops using, long time corneal contact lenses wearing, long time video terminal operating, lack of sleep and diabetes history. We should strengthen the publicity and education of the dry eye prevention and treatment, provide eye health guidance, prevention and treatment according to different risk factors, and protect the office workers’ eye health.

Objective: To explore the causes of low vision after cataract surgery. Methods: Patients who underwent cataract surgery at Joint Shantou International Eye Center of Shantou University and the Chinese university of Hong Kong ( JSIEC) from October 2011 to March 2013, whose fundus status could not be seen before surgery, and the best corrected visual acuity <0.3 in the first week after surgery, underwent a series of detailed ocular examinations, including visual acuity, best corrected visual acuity, intraocular pressure, slit-lamp examination, fundus examination, fundus photography and optical coherence tomography. If no organic lesions of the retina were found, then visual evoked potential examination and visual field examination were performed. Two doctors analyzed the examination results of the examination, made the diagnosis of different fundus diseases, and statistically analyzed the causes of low vision after cataract surgery. Results: A total of 5 608 cataract surgeries were performed in our hospital from October 2011 to March 2013. A total of 49 patients (49 eyes) with best corrected visual acuity worse than 0.3 within postoperative 1 week 20 male and 29 female, 31 right eyes and 18 left eyes, aged (69.11±12.05) years on average. The proportion of low vision after cataract surgery was 0.87%. 12 cases (24.5%) of high myopic chorioretinopathy, 10 cases (20.4%) of ellipsoidal band defect, 8 cases (16.3%) of diabetic retinopathy, 5 cases (10.2%) of macular holes, 4 cases (8.1%) of age-related macular degeneration, 3 cases (6.1%) of macular epiretinal membrane, 1 case (2.0%) of thinning macular retinal thickness, 1 case (2.0%) of retinitis pigmentosa, 1 case of retinoschisis (2.0%), 1 case of branch retinal artery occlusion (2.0%), 1 case of Behcet’s disease (2.0%), and 1 case of ischemic optic neuropathy (2.0%), 1 case of epiretinal membrane (2.0%). Conclusion: Among patients with low vision after cataract surgery, high myopic chorioretinopathy accounts for 24.5%, followed by ellipsoidal band defect, diabetic retinopathy, macular hole, age-related macular degeneration, and macular epiretinal membrane. The use of optical coherence tomography can detect subtle microscopic retinal structural changes that affect vision after cataract surgery. For patients with visible fundus before cataract surgery, routine optical coherence tomography contributes to evaluating the prognosis of the operation, facilitating doctorpatient communication, and improving the degree of surgical satisfaction.

General practitioners provide basic, continuous, comprehensive and holistic medical services to individuals and their families, which requires them to have a more “extensive” knowledge structure. However, within the limited training period, how to successfully complete subspecialty training and acquire the clinical skills and knowledge needed in community health services is an urgent problem which need to be explored. Based on the basic characteristics of community health service, the ophthalmology training of the standardized training of general practitioners, focus on the eye and systemic diseases, ophthalmic emergency and side-effect of systemic drug on eye would help general practitioners rapidly and accurately find and diagnose all kinds of serious emergent ophthalmologic diseases, and then refer to professional eye institutions in time, which avoid delay in diagnosis and treatment and save more valuable time for subsequent professional treatment. It would make the general practitioners become good healthy gatekeepers for the local community residents.

With the improvement of science and technology and the improvement of surgical methods, corneal refractive surgery has become the main way to treat myopia. The changes of corneal morphology and biomechanics after corneal refractive surgery are of great significance for early detection of postoperative complications and also affect the long-term stability after corneal refractive surgery. There are some differences in the changes of aspheric parameters and biomechanical properties in different surgical procedures and different postoperative recovery stages. Clarifying the reasons and mechanisms of these changes can provide some reference for clinical research.

A total of 126 senior of 5-year clinical medicine students in Sun Yat-sen University were recruited. After 1-week internship and direct ophthalmoscope training, a questionnaire survey was conducted to scrutinize students’ feedback about the training methods and learning difficulties during the internship. The results showed that most students thought that the direct ophthalmoscope played an important role in clinical work. However, students generally felt complicated and hard during the learning process due to the communication obstacle between teachers and students caused by the unavailability of vision sharing. In spite of this, most students are still willing to accept further direct ophthalmoscopy training.

The patient was treated with ‘left eye blurred vision for more than 20 years’. The patient underwent left trabeculectomy more than 20 years ago. Visual acuity oculus dexter (OD): no light perception (NLP), oculus sinister (OS): light perception (LP), and light positioning was accurate, right eye scleral staphyloma (nose), the anterior chamber was approximately 1/4 CT, the pupil was fixed and scattered, the lens was displaced into the vitreous cavity, and the left eye conjunctiva was filtered. The blister was flat, the anterior chamber was shallow, about 1/4 CT, and the iris layer was separated and floated in the anterior chamber. The upper iris incision led to smooth flow, C/D: 0.4. Intraocular pressure (IOP): R 13.0 mmHg, L 16.0 mmHg. Ultrasound biomicroscopy (UBM): in the right eye, anterior chamber angle was narrow in each quadrant, dislocation of the lens; anterior chamber of the left eye was shallow, anterior chamber angle of the temporal stenosis was narrow, the remaining quadrants were closed, iris lamellar separated. B-ultrasound: the right eye lens was displaced into the vitreous cavity. Diagnosis: left eye Iridoshcisis; right eye lens dislocation.

Endogenous fungal endophthalmitis is easy to be misdiagnosed because it is quite rare and early clinical features resembling uveitis. A 48-year-old female patient was admitted to Wuhan Aier Eye Hospital Hankou Hospital, her first diagnosis was uveitis, and the posterior anterior chamber puncture was confirmed as endogenous Candida endophthalmitis.

Helicobacter pylori (HP) infection is a risk factor for central serous chorioretinopathy (CSC). But the existing studies tend to support two distinctively different trends regarding the link between HP infection and CSC. The first group tend to support that: HP infection may be a risk of CSC, and the second tend to claim to no correlation between the two. This paper will review the literature on whether HP infection is a risk factor for CSC and discuss its pathogenesis.
