Central serous chorioretinopathy (CSC) is a common retinal disease caused by multiple factors, and its specific pathogenesis is not fully understood. there is no standard unified treatment plan for CSC, and common treatment options include observation and follow-up, retinal laser therapy, photodynamic therapy (PDT), anti-VEGF drugs, traditional Chinese medicine, and multiple modalities of combined treatment. Subthreshold micropulse laser (SML), as a new retinal laser, has good therapeutic effects on acute and chronic CSC without damaging effects on the retina. In this paper, we will review the mechanism of action and clinical application of subthreshold micropulse laser for the treatment of CSC, and provide some basis for the clinical selection of CSC treatment.
College of Ophthalmology, Eye School of Chengdu University of TCM, Chengdu 610075 According to the World Health Organization, more than 2.2 billion people worldwide are visually impaired or blind. Recent research advances have revealed the potential therapeutic value of Electrical Stimulation (ES) in a variety of retinal diseases. Transcorneal Electrical Stimulation (TES) not only has a positive effect on the retina and its associated structures, but also regulates neuronal activity in the brain, providing a new treatment option for retinal diseases. This paper reviews the applications of TES in retinitis pigmentosa (RP), age-related macular degeneration (AMD), retinal vascular disease, glaucoma and optic neuropathy in recent years. Relevant studies have confirmed that TES therapy is a safe and non-surgical neuromodulation tool. This paper aims to provide a comprehensive overview of TES research and explore its potential applications in the field of ophthalmology.
Objective: To explore the application of problem-based learning (PBL) combined with micro-teaching method in ophthalmology class. Methods: Sixty students of the ophthalmology internship course of Jinzhou Medical University were randomly divided into an experimental group and a control group. The control group used traditional teaching methods to compare the teaching effects of the two teaching methods. Results: The scores of the experimental group were better than those of the control group, and the difference was statistically significant(P<0.05). Conclusion: PBL combined with micro-teaching method can be applied in the clinical practice of ophthalmology students, which improves students’ comprehensive quality, creative thinking, comprehensive analysis and teamwork ability. Besides, it also mobilizes learning enthusiasm, improves students’ learning efficiency,improves theoretical knowledge assessment and clinical operation assessment results, leading to satisfactory teaching effect.
A 60-year-old woman was admitted to Chengdu Aidi Eye Hospital because of “dark shadow fluttering in the right eye for 1 month and vision loss for 8 days”. Visual acuity—with a myopic correction—was 0.1 with the right eye and 0.9 with the left eye. The right eye fundus presented a well-defined, irregular, grayish white area around the optic disc, and affected the fovea, corresponding to the visual field defect of the fundus lesion. Optical coherence tomography (OCT) showed that the ellipsoid bands in this region were irregular and absent, and several finger-like ridges were seen in the retinal pigment epithelium (RPE) layer. Fundus autofluorescence (AF): High fluorescence and some irregular low fluorescence in the affected area. Fundus fluorescein angiography (FFA): Fluorescence leakage was seen in the early stage, fluorescence staining and accumulation in the late stage. Indocyanine green angiography (ICGA): A well-defined low-fluorescence area centered on the optic nipple was observed. Diagnosis:Acute annular outer retinopathy. Treatment: Anti-inflammatory and improved blood circulation for 4 weeks, the gray and white ring of fundus disappeared and the visual acuity improved obviously
We reported two cases of posterior pole granuloma toxocariasis with different prognosis to remind ophthalmologists to attach importance to the active treatment. Two patients were diagnosed with posterior pole granuloma toxocariasis. One patient received prednisolone and pars plana vitrectomy combined with peeling of retinal membrane, and his vision was improved significantly. The other patient missed opportunity to perform surgery and lost his vision. It is important to make accurate diagnosis and active treatment for posterior pole granuloma toxocariasis. Eyes with posterior pole granuloma toxocariasis should be treated with surgery without delay to avoid visual loss when epiretinal membrane causes the absence of normal macular structure.
Objective: To investigate the predictive accuracy andeffect of capsular tension ring (CTR) implantation with fivenew generation intraocular lens (IOL) calculation formulas [Barrett Universal Ⅱ (BU Ⅱ ), Emmetropia VerifyingOptical (EVO), Kane, Pearl-DGS and Hill-RBF 2.0] in high myopia patients. Methods: This is a prospectivecase-control study. The patients were enrolled with an axial length (AL)≥27.00 mm, and underwent cataract surgery with AR40E IOL implantation at the Shaanxi Eye Hospital from December 2020 to September 2021. Thepatients were randomly assigned to the CTR implantation group (group A) and the non-CTR implantation group(group B). With the ocular parameters measured by the IOL-Master 700, the IOL power was calculated with theBU Ⅱ formula before surgery. The postoperative actual equivalent spherical diopter (SE) were recorded,and the predicted error (PE) and absolute error (AE) using the five formulas were recorded and compared at 1 week, 1 month, and 3 months, repsectively. Group A was divided to A1 (27.00 mm ≤ AL ≤ 30.00 mm) and A2 (AL>30.00 mm), and group B was divided to B1 (27.00 mm ≤ AL ≤ 30.00 mm) and B2 (AL>30.00 mm). The effects of CTR implantation and the accuracy of the formulaswere analyzed with different AL ranges. Results: A total of 63 patients (89 eyes) were included, aged (55.93±10.17) years old, with preoperative AL (30.30± 2.18) mm. There was no statistically significant difference in SE between groups A, A1, and A2 (P>0.05) at different postoperative times. While there was a statistically significant difference in SE between groups B, B1, and B2 (P < 0.05) at 1 week and 1 month after surgery, and between 1 week and 3 months after surgery. There was no statistically significant difference between 1 month and 3 months after suergery (P>0.05). There was no significant difference in the AE using the five formulas among groups A, B, A1, A2, B1, and B2 (H= 9.27, P= 0.06, H= 7.09, P= 0.13, H= 2.44, P= 0.66,H= 8.56, P= 0.07, H= 4.16, P= 0.39, H= 8.72, P= 0.07). There was no statistically significant difference in prediction error changes among the five formulas after CTR implantation (P>0.05). Conclusion: For cataract patients with AL ≥27.00 mm, the refractionvalue in the CTR implantation group tended to stabilizeafter one week of surgery. While in the non-CTR implantation group, the refractionvalue tended to stabilize after one month. CTR implantation had no effect on the accuracy and selection of the five formula, and the five IOL calculation formulas can be normally selected.
Objective: To investigate the effect of standard operation procedure in the intravitreal injection. Methods: A total of 504 patients visiting the fundus clinics of our hospital from September to December 2018 were selected in this study. The integration of nursing human resources, patient waiting time, patient and family satisfaction,and medical staff satisfaction were evaluated.
