Terson syndrome, also known as subarachnoid hemorrhage combined with vitreous hemorrhage syndrome, is a relatively rare ophthalmic condition. Patients mostly have impaired consciousness and communication difficulties due to intracranial hemorrhage, which makes it very easy to miss the diagnosis and the best time for treatment. This article reports the basic case of a 30-year-old male patient with sudden coma due to diffuse subarachnoid hemorrhage. And he had blurred vision in both eyes 1 month later, which was finally diagnosed as binocular terson syndrome. He was treated with vitrectomy in the left eye and vitrectomy + anterior retinal detachment surgery in the right eye. The visual acuity of patient was restored from finger count/5cm to corrected visual acuity of 0.3 in the left eye when 54 days after surgery and from manual/20 cm to corrected visual acuity of 0.12 in the right eye when 19 days postoperative.
In this case reportit describes a novel technique using indocyanine green gel for the surgical excision of conjunctival lymphangiectasia (CL). CL was found on the nasal side of left eye in a 50-year-old male. Surgical excision of the entire cystic lesion with an intact cyst wall was completed with the assistance of an indocyanine green (ICG) gel. No sutures were used throughout the entire procedure. Subsequent post operative follow-up was uneventful. Herein, we report a novel technique used to facilitate the identifcation and complete removal of an intraocular cystic lesion ensuring an intact cyst wall.
Objective: To assess changes of choroidal thickness (CT) in hyperopia children after 1 week using of 1% atropine.Methods: A total of 42 hyperopia children aged 4–7 years were included into the study.A single drop of 1% atropinegel was used twice a daily for 7 days in the subjects.The thickness of retina and choroid was measured by OCT, and the changes before and after using 1% atropine gel were analyzed at the subfovea and at 1.0 mm intervals (up to3.0 mm) from the fovea at superior, inferior, nasal, and temporal locations. Results: In the hyperopia children, baselineCT parameters were varied with the location(F=27.08,P<0.05).Compared with the fovea, the CT at the nasal side,2 mm and 3 mm above the fovea and 3 mm from the temporal side of the fovea were thinner (P<0.05).After using 1%atropine gel, there was no significant difference in the CT changes of subfoveal choroidal thickness and other sites ofparafovea (P> 0.05). There was no significant change in retinal thickness before and after using 1% atropine gel (P > 0.05).Conclusion: No changes were found in the thickness of choroid and retina in hyperopia children after short-term use of1% atropine gel.
Although amniotic membrane transplantation (AMT) has long been used as an essential surgical technique for ocular surface reconstruction, its role continues to evolve and expand. In the management of numerous ocular surface disorders, ranging from inflammatory to infectious, traumatic to neoplastic, the ability to perform AMT is a valuable addition to the skillset of any ophthalmologist. The purpose of this paper is to provide ophthalmologists with an updated, evidence-based review of the clinical indications for AMT in corneal and conjunctival reconstruction, reviewing its common and even experimental applications known to date. The methods of amniotic membrane preservation, the available commercial amniotic membrane products to date, and future directions for amniotic membrane use, including amniotic membrane extract eye drops (AMEED), are also discussed. It is paramount for ophthalmologists to stay up-to-date on the applications of AMT so as to effectively incorporate this versatile treatment modality into their practice,both in the operating room and in the clinic. By familiarizing the general ophthalmologist with its diverse applications, we hope to motivate general ophthalmologists to incorporate the use of AMT into their clinical practice, or provide guidance on how to recognize when referral to a corneal specialist for amniotic membrane application is prudent.
Objective: To understand the current status and influencing factors of self-preceived burden (SPB) in patients with wet age-related macular degeneration (AMD). Methods: 204 patiens with wet AMD who were treated in Zhongshan Ophthalmic Center, Sun Yat-sen University from January to November 2021 were enrolled as the study subjects with convenience sampling method. A general information questionnaire, SPB scale, family support self-assessment scale, and medical coping questionnaire were collected from the subjects for assessment. Results: The patient’s SPB score was 21.98±6.68, which is generally mild SPB. The SPB level of patients with wet AMD was negatively correlated with family support (r=-0.326, P<0.001) and coping (r=?0.365, P<0.001), and were positively correlated with avoidance (r= 0.456,P<0.001), and surrender (r=0.310, P<0.001) coping style. Multiple linear regression showed that the patients who lived alone, were elder and self-funded, had binoclur diseases and used avoidance coping, had higher SPB. While the patients with high education and family support had lower SPB. Conclusions: It is still needed to pay attention to the patients with AMD having mild SPB. Medical workers should focus on patients with elder age, low education level, low family income, self-funded, living alone, binocular disease and low vision in their work, and provide timely psychological counseling to reduce the SPB level of patients.
Exosomes are nanoscale vesicles with a diameter of 30 nm to 150 nm, which are composed of lipid bilayers, proteins, and genetic material. Almost all types of cells in the human body can secrete exosomes. Tey play key roles in cellular communication, immune regulation, infammatory responses and neovascularization. At present, exosomes have been widely studied in tumors, cardiovascular and urinary systems. In recent years, the role of exosomes in eye diseases has attracted more and more attention. The exosomes play an important role in the occurrence and development of common eye diseases such as keratopathy, age-related macular disease, diabetic retinopathy, glaucoma, etc. Currently it is a hot topic that the therapeutic potential of extracellular vesicles derived from diferent mesenchymal stem cells in eye diseases. Te exosomes derived from mesenchymal stem cells have anti-infammatory, anti apoptotic, neuroprotective and tissue repairing effects, which are similar to those of mesenchymal stem cells. Thus, exosomes may be a novel direction of research in the treatment of many eye diseases without cell therapy. Further understanding of the biological characteristics of exosomes and the latest research progress of exosomes in common eye diseases will provide reference for the pathogenesis and prevention strategies of related eye diseases.
Tyroid-associated ophthalmopathy is an organ-specifc autoimmune disease with complex pathogenesis. It is the most common orbital disease in adults, and its incidence increases year by year. Tis disease can not only lead to appearance changes such as eyeball protrusion, eyelid retraction, eyelid cleat enlargement, eye movement disorders, and patients are ofen accompanied by red eyes, eye pain, dryness, foreign body sensation, diplopia, vision loss and other uncomfortable symptoms, among which the incidence of ocular surface diseases is signifcantly higher than that of normal people, but its specifc pathogenesis needs to be further explored. Current studies have shown that ocular surface injury in patients with thyroid-associated ophthalmopathy is mainly related to increased ocular surface exposure, infammatory invasion, and hormonal changes. Te pathological changes of cornea, conjunctiva, tear flm, meibomian gland and other tissues involved are the direct causes of different clinical symptoms of patients. In this paper, through the analysis of recent domestic and foreign studies on thyroid-associated ophthalmopathy and ocular surface diseases, the pathological changes and mechanism of ocular surface injury in thyroid-associated ophthalmopathy were reviewed.
Traumatic optic neuropathy is a blinding eye disease that causes severe damage to vision due to external force damage to the optic nerve.. Autophagy is an intracellular degradation pathway that helps maintain the balance between the synthesisof normal cell components and the breakdown of damaged organelles and toxic cellular components. Autophagy markers are increased in optic nerve and retina after optic nerve trauma. Autophagy may play different roles on retinal ganglion cells (RGCs) at different stages of traumatic optic neuropathy. Most studies have shown that upregulating autophagy can attenuate RGCs death in traumatic optic neuropathy; however, it has also been suggested that inhibition of autophagy at ultra-early stage after injury can inhibit RGCs axonal degeneration. In this review, we reviewed the definition and function of autophagy, the mechanism of autophagy, and summarized the change of autophagy level after optic nerve trauma, as well as the effects of autophagy in RGCs after optic nerve trauma.
Objective: The etiology and clinical characteristics of patients with binocular diplopia as main symptom were investigated using retrospective analysis method. Methods: The clinical data of patients with binocular diplopia treated in department of ophthalmolog y, affiliated hospital of Weifang Medical University from January 2021 to March 2022 was summarized and the etiology and clinical characteristics retrospectively. Results: There were totally 29 patients, 16 males and 13 females, aged from 17 to 81 years, with an average of (59 ± 14) years; among them, there were 8 cases derived from vascular factors, including 5 cases with cerebrovascular disease, 2 cases with posterior communicating artery aneurysm and 1 case with internuclear ophthalmoplegia. There were 8 cases derived from inflammatory and immune factors, including 4 cases with myasthenia gravis, 2 cases with Tolosa-Hunt syndrome, 1 case with hypertrophic meningitis and 1 case with inflammatory pseudotumor. There were 9 cases derived from endocrine factors, including 5 cases with peripheral neuropathy in diabetes and 4 cases with thyroid related ophthalmopathy. There were 2 cases derived from tumors, including 1 case with oculomotor schwannoma, 1 case with orbital MALT lymphoma and there were 2 other cases of trauma. Conclusions: The etiology of binocular diplopia is complicated and the clinicians should pay attention to the screening of systemic diseases of patients refer to the principle of localization diagnosis first and qualitative analysis next so as to improve the diagnostic accuracy and reduce the misdiagnosis rate.
Progressive visual impairment is more common in ametropia, primary open-angle glaucoma, cataract, hereditary and metabolic diseases of optic nerve and retina, and less common in orbital and intracranial masses. Intracranial arachnoid cysts are usually asymptomatic benign congenital lesions with a small number of visual impairments. The absence of the bone wall of the optic canal was seen in normal subjects with good gasification of the posterior ethmoid sinus and sphenoid sinus. In this case report we describe a 59-year-old man with a left temporal arachnoid cyst and a defect of the bone wall of the optic canal complained of left visual field defect and blurred vision for more than one year. The mechanism of visual dysfunction was analyzed by collecting the patient’s medical history, imaging data and the results of visual function examination.
