Filter by:The goal of this clinical trial is to test in patients with glaucoma and elevated pressure in the eye. The main questions it aims to answer are: • ability to lower pressure in the eye • safety in the eye and the body of patients with elevated pressure in the eye. Patients will be randomly given either: - 0.5% (5 mg/mL) SBI-100 Ophthalmic Emulsion - 1.0% (10 mg/mL) SBI-100 Ophthalmic Emulsion - Placebo Ophthalmic Emulsion Patients will be tested before starting and will have one drop of the product placed into each eye twice a day for 14 days, by the site and by the patient. At the end of the study, researchers will compare the groups to see if there is a change from before use of SBI-100 Ophthalmic Emulsion to the end of study.
The goal of this observational study is to examine the anterior segment anatomical parameters associated with the scleral spur and cornea for risk profiling of primary angle-closure glaucoma (PACG). The main question it aims to answer is: • Are there new anatomical parameters of the anterior segment of the eye that can be used early for risk profiling for PACG? Researchers will compare PACG and narrow angle groups to see if there are some anatomical parameters that can distinguish the two.
As ab externo metal probe trabeculotomy cannot achieve 360-degree circumferential angle surgery, prolene suture can be used to achieve this without the need for an illuminated microcatheter. In order to combine the advantages of the use of viscoelastic and those of circumferential trabeculotomy, this technique (Visco-Circumferential-Suture- Trabeculotomy "VCST") was previously used successfully in PCG. (7) In the current study , the authors hypothesize that combination of VCST with phacoemulsification in primary angle closure glaucoma patients may have an added affect to phacoemulsification alone in cases with more extent of angle damage and that the injection of a viscoelastic into both ends of the unroofed SC before its cannulation by a polypropylene suture and subsequent circumferential trabeculotomy may facilitate circumferential cannulation of SC and hence the trabeculotomy and increase the success of the technique
Comparison of Efficacy and Ocular Surface Disease Assessment between BRIDIN-plus Eye drops and Combigan Eye drops in Glaucoma or Ocular Hypertensive Patients : Phase 4, Parallel Group Design, Investigator-blind, Active-control, Randomized, Multi-center Trial
The aim of this study was to verify whether prostaglandin analogue (PA) eye drops influence the retinal thickness of glaucomatous patients undergoing trabeculectomy (TRAB) surgery. We selected eyes of patients with glaucoma with surgical indication for TRAB who were using PA eye drops and without previous retinal alterations, from the Centro de Referência em Oftalmologia (CEROF) from the Federal University of Goiás and Fundação Banco de Olhos de Goiás (FUBOG). Patients were divided into 2 groups: the study group (SG) and the control group (CG). In the CG, the PA was suspended between 30 and 60 days before the preoperative exams were performed (maximum of 15 days before surgery for both groups). All patients included were submitted to various eye exams before the procedure, and postoperatively on 3 occasions: 1 to 3 days ("PO1"), 6 to 9 days ("PO7") and 27 to 30 days ("PO30") after surgery.
This work aims to study the peripapillary and macular microvascular changes in primary open angle and primary angle closure glaucoma using Optical Coherence Tomography Angiography (OCTA).
The goal of this study is to compare efficacy and safety of Dorzotimol eye drops, 20 mg/mL + 5 mg/mL manufactured by JADRAN-GALENSKI LABORATORIJ d.d. (Croatia) aimed at lowering elevated IOP in patients with ocular hypertension and primary open-angle glaucoma (POAG) versus Cosopt® eye drops, 20 mg/mL + 5 mg/mL manufactured by Laboratoires Merck Sharp & Dohme-Chibret, France. The main questions it aims to answer are: - if the efficacy of the investigational drug and the reference drug in patients with ocular hypertension and primary open-angle glaucoma is equal; - if the safety of the investigational drug and the reference drug in patients with ocular hypertension and primary open-angle glaucoma is equal. A total of 110 participants were screened and randomized 1:1 to the investigational drug (Dorzotimol) group or the reference drug (Cosopt) group. 55 patients were recruited in each group. Researchers compared the investigational drug (Dorzotimol) group with the reference drug (Cosopt) group to see if the efficacy and safety of the investigational drug and the reference drug in patients with ocular hypertension and primary open-angle glaucoma are equal.
The goal of this study is to compare efficacy and safety of Dorzol 20 mg/mL Eye Drops manufactured by JADRAN-GALENSKI LABORATORIJ d.d. (Croatia) aimed at lowering elevated IOP in patients with ocular hypertension and primary open-angle glaucoma (POAG) versus TRUSOPT 20 MG/ML Eye Drops manufactured by Laboratoires Merck Sharp & Dohme-Chibret, France. The main questions it aims to answer are: - if the efficacy of the investigational drug and the reference drug in patients with ocular hypertension and primary open-angle glaucoma is equal; - if the safety of the investigational drug and the reference drug in patients with ocular hypertension and primary open-angle glaucoma is equal. A total of 118 participants were screened and randomized 1:1 to the investigational drug (Dorzol) group or the reference drug (Trusopt) group. 59 patients were recruited in each group. Researchers compared the investigational drug (Dorzol) group with the reference drug (Trusopt) group to see if the efficacy and safety of the investigational drug and the reference drug in patients with ocular hypertension and primary open-angle glaucoma are equal.
Materials and Methods 1. General information This study enrolled 153 patients with congenital glaucoma who were treated at our hospital from January 2021 to December 2022. These patients were divided into an observation group (n = 76) and a control group (n = 77) using a random number table. The inclusion criteria were as follows: (1) meeting the diagnostic criteria for glaucoma, (2) following the attending doctor's recommendations to receive surgical treatment, and (3) volunteering to participate in the study. The exclusion criteria were as follows: (1) severe organic dysfunction, (2) cardiovascular and/or cerebrovascular diseases, (3) hypertension, (4) contraindications for surgery, (5) other eye diseases, (6) communication disorders, and (7) mental illnesses. Informed consent with signature was obtained from every participant, and the study has been approved by the hospital's ethics committee. 2. Research methods The control group was provided with routine care, including warm reception and provision of a quiet, clean, and well-ventilated ward environment for good rest. Patients were educated to broaden their knowledge of the disease and related surgical treatment, particularly the importance and outcomes of surgical treatment, thereby allaying their feeling of fear and boosting their confidence in recovery. Meanwhile, patients were encouraged to break their unhealthy habits, avoid bad diet choices, and take medications on time. The observation group received CBNI described as follows: (1) A cognitive-behavioral intervention group was set up by several nurses who had a background of systematic cognitive intervention training, were able to independently develop comprehensive behavioral intervention plans and assess a patient's cognitive level, and had an adequate understanding of the fundamentals of cognitive behavioral intervention. Through thorough communication with patients, these nurses were supposed to identify their major concerns and assess their cognitive behavior. Based on the assessment results, psychological counseling was provided for every patient, with each session lasting at least 50 minutes. In addition, the nurses were required to reassure all patients by proactively introducing the precautions of surgery and nursing care. (2) Psychological intervention was accessible to those who felt resistant to their treatment plans or developed inferior feelings due to visual impairment to establish a good relationship with patients and help them better cope with unhealthy emotions. Professional education was provided through communication with patients so that they could gain detailed knowledge of the disease. Chatting and music were useful to relieve tension and psychological stress. Regular patient support groups were organized to help patients develop confidence and a positive attitude toward the disease. (3) Health education was provided through self-developed booklets and question-and-answer sessions to publicize the fundamental knowledge and make sure all patients have a full understanding of the disease and related treatments. The nurses were also required to closely monitor patient compliance from the perspectives of diet, lifestyle, psychology, and treatment. (4) Dietary guidelines were set out to encourage a light, healthy diet with fruits and vegetables, free of irritating food, and containing a limited amount of oily food. It should be noted that smooth bowel movements are essential to prevent increased IOP induced by constipation. Therefore, the recommended diet is high in dietary fiber and fruits. (5) Behavioral guidelines were developed to address the importance of quitting tobacco use and prevent eye strain due to excessive eye use with tailored eye care plans. The nurses were responsible for guiding the proper use of eye drops by patients, reminding all patients to seek medical attention immediately if they experienced any eye discomfort, and stressing the risk of increasing IOP due to prolonged periods of looking down and other unhealthy habits. 3. Statistical analysis The software SPSS22.0 was used for data analysis. Measurement data were expressed as "mean ± standard deviation (x±s)", and comparisons between the two groups were examined by the t-test. Enumeration data were represented as percentages (%) and inter-group comparisons were examined using the χ2 test. Significance was set at the level of P <0.05.
The aim of this study is to compare Mydrane ®, mydriatic eye drops and Mydriasert ® in terms of pupil site stability, surgical time, visual field and anterior chamber configuration modifications among primary open angle glaucoma (POAG) patients during cataract extraction surgery.
