Outcomes From Hyperbaric Oxygen (HBO2) Treatment for Emerging Indications

This study will evaluate the effectiveness of hyperbaric oxygen therapy (HBOT) on treating emerging indications (i.e., conditions that have shown to potentially benefit from HBOT) using the Multicenter Registry for Hyperbaric Oxygen Treatment. The study team aims to collect ongoing data on how well HBOT treats these emerging indications, and to add these data to the growing HBO Registry. The research team hypothesizes that HBOT will result in improvements of the condition of the various emerging indications.

Comparing Two Surgical Methods to Prevent Pterygium Regrowth

This study compares two surgical techniques for preventing the regrowth of a pterygium, a non-cancerous growth on the eye. After surgically removing the pterygium, surgeons will cover the area with either a flap of nearby tissue that is rotated into place (Rotational Flap) or with a free graft of tissue taken from under the upper eyelid (Autograft). The main goal is to see which method is better at preventing the pterygium from growing back over a 6-month period. A total of 342 patients with a primary pterygium will be randomly assigned to one of the two surgical groups.

Comparison Of Keratometric Readings Pre and Post Pterygium Excision With Conjunctival Autograft Transplantation

Pterygium, often called "surfer's eye," is a common eye condition in which a raised, fleshy growth of tissue extends from the white part of the eye onto the clear cornea. This growth can cause redness, irritation, blurred vision, and, in advanced cases, changes in the curvature of the cornea leading to distorted vision (astigmatism). The condition is more frequent in people exposed to sunlight, dust, and dry environments. The standard treatment for symptomatic pterygium is surgical removal. However, simple removal has a high chance of recurrence. To reduce this risk, surgeons commonly use a technique called conjunctival autograft transplantation, where a small piece of the patient's own conjunctiva is placed over the area after excision. This method not only lowers the recurrence rate but may also improve vision by reducing corneal irregularities. This study is designed to measure the changes in corneal curvature (keratometric readings) before and after pterygium excision with conjunctival autograft transplantation. By comparing preoperative and postoperative measurements, the study aims to determine how much this surgery improves corneal shape and reduces astigmatism. The hypothesis is that pterygium excision with conjunctival autograft transplantation will lead to a significant improvement in keratometric readings and reduce irregular astigmatism, thereby improving visual quality. This research will provide local evidence of the effectiveness of this procedure and help guide treatment strategies for patients suffering from pterygium-related visual problems.

A Clinical Trial on Safety and Efficacy of CBT-001 in Patients With Pterygium

The objective is to evaluate the safety and efficacy of low dose and high dose CBT-001 eye drop dosed twice daily for 24 months compared to vehicle in reducing conjunctival hyperemia and preventing pterygium progression in eyes with pterygia.

Clinical Outcomes of Sutured Versus Sutureless Conjunctival Autograft in Primary Pterygium Excision

The goal of this study is to find out if a certain technique in pterygium excision surgery ,using no sutures, is better than the technique mostly used ,which uses sutures. Investigators aim to find out whether the no sutures technique provides better efficiency and patient satisfaction than the traditional approach. They predict that if this study provides evidence of the advantages of this technique over the one used, surgeons would be encouraged to use it instead. Because not only would the patient benefit, the surgeon also may save operative time and effort used in the technique which uses sutures.

Comparison of Recurrence Between Mini-SLET and Limbal-Conjunctival Autograft Techniques in Primary Pterygium

The surgical treatment options for pterygium, an abnormal growth on the eye's frontal surface can be treated with several surgical techniques. The rates of pterygium coming back varies depending on the surgical technique employed and other factors related to the patient and surgery. The objective of this study is to assess the efficacy and safety of incorporating a single amniotic membrane with stem cells in the treatment of primary pterygium, aiming to enhance surgical outcomes and minimize recurrence rates.
