Objective: This study used Doppler imaging and contrast-enhanced ultrasound to measure ocular haemodynamic of patients with primary angle-closure glaucoma (PACG) and primary open-angle glaucoma (POAG), to investigate the association between the blood flow changes and glaucoma. Methods: Doppler imaging and contrast-enhanced ultrasound were performed on 16 PACG patients (20 eyes, PACG group), 8 POAG patients(10 eyes, POAG group) who were diagnosed in the Department of Ophthalmology, the Second Affiliated Hospital of Harbin Medical University from Dec. 2012 to Mar. 2014. The normal eyes from 10 persons were selected as control group. The flow velocity of ophthalmic artery, central retinal artery, and posterior ciliary artery were observed, including the peak systolic velocity, diastolic peak velocity, resistance index, and the arrival time and departure time of the ultrasound microbubbles (SonoVue). Results: Compared to control group, the arrival timeof the ultrasound microbubbles (SonoVue) of ophthalmic artery of patients with POAG increased (P=0.035),and the departure time of ophthalmic artery of patients with PACG and POAG increased (P=0.010). Both peak systolic velocity and diastolic peak velocity of the ophthalmic artery and short posterior ciliary artery of patients with PACG and POAG and the central retinal artery of patients with POAG decreased (P=0.003). Meanwhile, the resistance index of ophthalmic artery of patients with PACG and POAG and the central retinal artery of patients with POAG were higher than those in the control group (P<0.001). Conclusion: The flow velocity of ocular vascular was worse than that of normal group respectively. This study provides a new technology for the diagnosis of glaucoma and the evaluation of the flow velocity of ocular vascular.

Frosted branch angiitis (FBA) is a rare acute retinal vasculitis which often occurs in healthy adolescents. The etiology of FBA is unknown, but its occurrence may be related to viral infection, glucocorticoid therapy is effective and has a good prognosis. FBA may also be secondary to infectious and systemic diseaseswith poor prognosis. In this paper, we reviewed a case of FBA secondary to allogeneic hematopoietic stem cell transplantation, which was relieved after treatment and had a good prognosis.

Heredity plays an important role in the pathogenesis of eye and ear dysfunction in children and adolescents. Because of common neural endodermal and ectodermal origins, the eyes and ears have the similar networks of genes Therefore, when pathogenic mutations occur in common genes, it can lead to loss of double sensation in the eyes and ears. There are more than 70 etiologies associated with the deafblindness, including CHARGE, Usher, Down, Stickler, Alport, Wolfram and Waardenbur syndromes, which are the most common syndromic ophthalmic genetic diseases with hearing and optic nerve/retinal abnormalities. Other abnormalities such as chromosomal and embryonic abnormalities can also lead to hearing and vision impairment, like Down and Dandy Walker syndromes. Some known genetic variants in ocular genetic diseases can also lead to hearing loss, such as OPA1 gene. Due to genetic heterogeneity, the clinical diagnosis of ocular and ear syndrome is often difficult, especially for infants and young children. With understanding the clinical features of eyes and ears in genetic syndrome,is conducive to early detection and accurate diagnosis, and when the ocular phenotype in the syndrome is atypical, it can be assisted by other systematic phenotypes such as the ear. At the same time, clear diagnosis is important for lifelong monitoring of visual and auditory function, as well as for eugenic genetic counseling.

Objective: To measure the thickness of retinal ganglion cell layer and inner limiting membrane-retinal pigment epithelium layer in the macular region, and analyze its correlation with new-onset ischemic stroke. Methods: By using a prospective study, 30 healthy subjects (60 eyes) who underwent physical examination in Affiliated Hospital of Weifang Medical University from December 2021 to March 2022 were selected as the control group (Group A). Thirty age-matched patients with new-onset ischemic stroke admitted at the same time (60 eyes) were selected as the stroke group (Group B). The ganglioncelllayer (GCL) and innerlimitingmembrane-Retinalpigmentepithelium (ILM-RPE) were compared between the two groups. It included the thickness and mean GCL thickness/Mean Volume thickness of ILM-RPE (GCL/ILM-RPE thickness ratio). Results: A total of 120 eyes were included, with 60 eyes in group A and B. The average GCL thickness in group A was (83.5±4.7) μm, and the average GCL thickness in group B was (78.7±10.5) μm,and the difference between groups was statistically significant (P<0.001). The minimum thickness of GCL in group A was (80.4±4.4) μm, and the minimum thickness of GCL in group B was (70.7±16.3) μm, showing statistical significance(P<0.001). The thickness of the central subregion of ILM-RPE in group A was (247.5±19.8) μm, and the thickness of the central subregion of ILM-RPE in group B was (241.6±36.3) μm, and the difference was not statistically significant between two groups (P=0.393). The mean volumetric thickness of ILM-RPE in group A was (278.4±9.8) μm, and the mean volumetric thickness of ILM-RPE in group B was (278.5±15.3) μm, and the difference was not statistically significant (P=0.448). The GCL/ILM-RPE thickness ratio of group A was (0.300 3±0.012 2), and that of group B was (0.286 2±0.028 6), showing a statistical difference between groups (P<0.001). Conclusion: Ischemic stroke affects the GCL thickness and the thickness ratio of GCL/ILM-RPE, which may be related to new-onset ischemic stroke.

Objective: With the help of artificial intelligence (AI) based fundus screening remote referral telemedicine system,it enables us to explore the remote screening mode of patient-community-hospital, and promote the two-way referral and ophthalmic graded diagnosis. This investigation provides certain practice experiences for prefecture-level medical institutions to carry out AI screening for fundus diseases. Methods: Ophthalmologic examination was performed on 4,886 patients in primary medical institutions through AI-aided remote screening, and the final fundus diagnosis conclusion was formed after AI preliminary judgment and manual review. Through the Medical Consortium and specialty alliance model, the results of the AI diagnosis system and the audit results of superior physicians for 4 886 patients in primary care institutions were compared and analyzed, and the credibility and feasibility of the AI diagnosis system application in the screening of common ophthalmic diseases were discussed. Results: The sensitivity and specificity of AI detection of diabetic retinopathy were 94.70% and 96.06%, respectively. In the diabetic macular edema classification, the sensitivity and specificity were 96.43% and 96.55%, respectively. In the age-related macular degeneration classification, the sensitivity and specificity were 77.55% and 95.74%, respectively. Meanwhile, it also plays a role in screening common fundus diseases such as pathological myopia, cataract and glaucoma. Conclusion: The AI-aided remote screening system has high sensitivity and specificity for most of fundus diseases, indicating it is promising for fundus diseases screening in primary medical institutions. It is conducive for primary hospitals or community hospitals to carry out the initial diagnosis of fundus diseases, as well as the implementation of graded diagnosis and treatment of ophthalmology, which has reference and promotion significance.

Objective: To screen the eyes of term neonates and analyze the occurrence and characteristics of eye diseases. Methods: The eye screening results of 4 594 term neonates admitted to the Second Affiliated Hospital & Yuying Children's Hospital of Wenzhou Medical University from January 2021 to June 2022 were recorded and retrospectively analyzed. Results: The  total abnormal rate of neonatal eye screening was about 10.54%, among which the abnormal rate of fundus was about 6.38%. Common diseases of the anterior segment included neonatal dacryocystitis, conjunctivitis, hemangioma, entropion, cataract, et al. Common diseases of the posterior segment included retinal leukoplakia, retinal hemorrhage, familial exudative retinopathy, et al. Conclusions: The wide-angle infant fundus screening instrument could detect neonatal occult ophthalmopathy early. And some blinding ophthalmopathies might need early treatment. In the future, it is necessary to establish and improve the screeningand the follow-up mechanism system for the neonatal ophthalmopathy.

Objective: To analyze the clinical characteristics of endogenous endophthalmitis caused by Klebsiella pneumoniae in diabetic patients, and summarize the treatment experience and evaluate its prognosis. Methods: A retrospective case analysis was performed on 7 patients (8 eyes) with endogenous endophthalmitis caused by Klebsiella pneumoniae, who were admitted to the Affiliated Eye Hospital of Shandong University of Traditional Chinese Medicine from January 2019 to August 2022. The age, gender, origin of infection, time of treatment, visual acuity before and after treatment, intraocular pressure, slit lamp examination, fundus examination, ophthalmic B-mode ultrasound, treatment methods, infection control and recurrence were analyzed. Results: The mean age of the seven patients was (63±17.6). There were five males (71.4%) and 2 females (28.6%). Postoperative visual acuity was NLP in seven eyes (87.5%) and LogMAR visual acuity was 0.2 in one eye (12.5%). Visual acuity was related to the patient’s visit time and the visual acuity at visit. Six cases (85.7%) had fever before treatment. Fever was a risk factor for Klebsiella pneumoniae endophthalmitis infection. Eight eyes (100%) had mixed conjunctival congestion, and one eye (12.5%) had abscess in the anterior chamber. Seven eyes (87.5%) underwent vitrectomy combined with intravitreal drug injection, and one eye (12.5%) underwent intravitreal drug injection alone. Infections were controlled in all eight eyes without enucleation. Intraocular pressure was normal during the follow-up period, and there was no infection recurrence. Conclusions: Klebsiella pneumoniae is the main pathogen of endogenous endophthalmitis and is prone to occur in people with diabetes. The onset of the disease progresses rapidly. The early clinical manifestations are not typical, and the prognosis is closely related to the duration of the disease and the timing of treatment. Early treatment can restore some vision.

Purtscher-like retinopathy is a rare retinal vascular disease. In this study,the clinical characteristics of 13 cases of Purtscher-like retinopathy were analyzed. Typical fundus abnormalities included Purtscher flecken (22 eyes), cotton-wool spots (22 eyes), retinal hemorrhages (13 eyes), macular edema (22 eyes), swelling of optic disk (12 eyes), and falsecherry red spots (10 eyes). The abnomal manifestations of fluorescein angiography included non perfusion area of capillaries (21 eyes), and precapillary occlusion (22 eyes). Among 13 patients, 9 patients were treated with glucocorticoids and immunosuppressive drugs, and 4 patients were treated with circulation-improving and neurotrophic drugs. During the follow-up period of two months to five years, four patients (six eyes) experienced neuroepithelial atrophy and persistent low vision (<0.1). Based on literature review, we proposed that the prognosis of vision in Purtscher-like retinopathy may be associated with macular edema and the formation of capillary non-perfusion.

Objective: To observe the clinical efficacy of medial-inferior wall orbital decompression combined with fat decompression in the treatment of moderate-to-severe thyroid associated ophthalmopathy (TAO). Methods: A retrospective analysis was performed on 25 patients (31 eyes) with moderate-to-severe TAO from January 2020 to January 2022 in Eye Hospital of Zhejiang University, who were treated with medial-inferior wall orbital decompression combined with fat decompression. All of patients were given orbital computed tomography to measure visual acuity, exophthalmos, diplopia and ocular appearance before operation. The preoperative and postoperative exophthalmos, visual acuity and diplopia before and after operation were taken as efficacy evaluating indicators. The related data was counted and analyzed statistically. Results: After operation, the reduction of exophthalmos was 2-6 mm, with an average of (3.45±0.93) mm, the volume of intrazonal fat-removal was 1.4-3.6 mL, with an average of (2.33±0.66) mL, with a satisfactory appearance. There were 4 cases of preoperative diplopia and 2 cases of new diplopia after operation, all of which were mild diplopia. Diplopia did not exacerbate after operation in the patients who had diplopia before operation. Conclusion: Medial-inferior wall orbital decompression combined with fat decompression in the treatment of moderate-to-severe TAO can effectively expand orbital volume, reduce exophthalmos, improve appearance with a concealed beautiful surgical incision, showing its good clinical efficacy.
