To summarize the nursing experience of 20 cases of high myopia complicated with fixed esotropia. Before surgery, psychological nursing and self-care education were necessary. After the operation, ocular symptoms and complications should be closely observed and treatment in a timely manner. Explicit instructions after discharge and telephone follow-up played a pivotal role in improving clinical efficacy, preventing complications and enhancing patients' quality of life.

PURPOSE: To explore the treatment and continuing nursing of patients diagnosed with senile and diabetic cataract. METHODS: In total, 142 patients diagnosed with senile and diabetic cataract admitted to Zhongshan Ophthalmic Center from January to December 2014 were randomly assigned into groups A and B. In group A, patients received conventional instruction after discharge, and those in group B additionally received continuing nursing care after discharge including ocular nursing, use of anti-diabetic drugs, psychological nursing, diet nursing, self-monitoring guidance, re-examination and regular follow-up according to the patients' conditions...

Accommodation is an important function of the human eye, which can change the parameters of ocular refractive system and also has a strong correlation with the development of myopia and presbyopia. Several subjective measurements have been applied in accommodation assessment such as push-up test, push-down test and minus-lens procedures. It can be measured objectively by measuring the change in refraction of the eye with dynamic retinoscopy or autorefractor. This article reviews the application of measurement of accommodative amplitude and research progress in accommodation, providing clinical information for further studies...

PURPOSE: To investigate the correlation of various corneal hysteresis (CH) factors in Chinese adults. METHODS: From January 2009 to November 2011, the healthy right eyes of a total of 292 adults were recruited into the study. Goldmann-correlated intraocular pressure (IOPG) and CH were measured using an ocular response analyzer (ORA). Central corneal thickness was measured using the ORA's integrated handheld ultrasonic pachymeter. The IOLMaster was used to obtain the ocular biometric measurements including axial length, anterior chamber depth, and keratometric values...

Diabetic retinopathy (DR), a major microvascular complication of diabetes, has emerged as a leading cause of visual impairment and blindness among adults worldwide. However, aside from pathological damage, the traditional laser and multi-needle operation treatments required for more advanced disease can cause further damage to the visual field and increase the operation risk. Therefore, the development of new therapeutic strategies for the prevention and treatment of DR is essential. Some emerging evidence now indicates that pigment epithelium-derived factor (PEDF), a multifunctional protein, can target multiple pathways to exert neurotropic, neuropro- tective, anti-angiogenic, anti-vasopermeability, anti-inflammation, anti-thrombogenic, and anti-oxidative effects against DR...

PURPOSE: To investigate the effect of diplopia on the daily life of patients after strabismus surgery and to explore appropriate nursing care measures. METHODS: A total of 200 patients who developed postoperative diplopia underwent telephone follow-up to evaluate the influence of diplopia on their daily lives. SPSS 19.0 statistical software was utilized for data analysis. RESULTS: Postoperative diplopia affected patients' physical activity (49%), attention (39...

PURPOSE: To present a case of frosted branch angiitis with tuberculous meningoencephalitis who was followed up for 18 months after treatment. METHODS: Case report. RESULTS: A 19-year-old female with tuberculous meningoencephalitis complained of bilateral blurred vision, and presented with frosted branch angiitis and macula edema in both eyes. Treatment with systemic glucocorticoid and standard anti-tuberculosis medicine totally resolved the retinal periphlebitis and macular edema, with vision improvement achieved at the 18-month follow-up...

PURPOSE: Oxygen-induced retinopathy (OIR) is a robust and widely used animal model for the study of retinal neovascularization (NV). Dextran perfusion and Griffonia simplicifolia isolectin B4 (GSI-B4) staining are two common methods for examining the occurrence and extent of OIR. This study provides a quantitative comparison of the two for OIR detection. METHODS: At postnatal day 7 (PN7), fifteen C57BL/6J mice were exposed to a 75% hyperoxic condition for 5 days and then returned to room air conditions...

PURPOSE: To compare the education effect of video demonstrations and conventional teaching on the prevention and control of myopia. METHODS: Eighty students were randomly divided into an experimental (n = 40) and a control (n = 40) group, and each group was split into two classes of 40 students. The students in the experimental group attended classes mainly based on video demonstration and those in the control group received conventional teaching. All students then undertook a test and the examination scores were statistically compared between the two groups...

The femtosecond laser has a number of advantages, such as short pulse time, high instantaneous power, high repetition rate, low monopulse energy, and small thermal effect. Femtosecond laser-assisted small incision lenticule extraction (SMILE) is becoming the new direction in refractive surgery, and the ocular surface changes after SMILE are attracting increasingly more attention. This article reviews adverse effects, including dry eye, injury of corneal nerves, and ocular surface inflammation, occurring after SMILE...

Congenital cataract is a common cause of childhood low vision or blindness worldwide. Early surgery should be performed in sensitive vision development period to avoid vision deprivation in cases of strabismus and nystagmus development. Postoperative recovery of visual function is of great significance for these patients and should include proper postoperative aphakia correction by the application of a contact lens and secondary implantation of an intraocular lens (IOL). Patients should receive amblyopic training after surgery to improve their postoperative visual acuity...
