Clinical Trial Summary

Different Treatment Approaches of Presumed Trematode-Induced Uveitis including periocular injection and medical treatment Nd laser treatment

Clinical Trial Description

Uveitis, characterized by inflammation of the uvea, is a complex and potentially sight-threatening ocular condition that can result from various etiologies. Among causes of uveitis, trematode-induced uveitis represents a distinct and intriguing subset characterized by the presence of a single or multiple pearl like nodules in the anterior chamber (AC) or less commonly in the conjunctive, cornea or even in the ciliary body and posterior segment. Trematodes, or parasitic flatworms, have been implicated in causing uveitis through the migration of larvae or adult worms into the eye, triggering an inflammatory response 1. Despite its rarity, trematode-induced uveitis poses diagnostic and therapeutic challenges due to the diversity of trematode species and the lack of standardized treatment protocols 2. The treatment of trematode-induced uveitis typically involves addressing the underlying parasitic infection and managing the associated inflammation. Various treatment modalities have been reported in literature. Antiparasitic medications have been tried by some authors. Advantages include targeting the underlying cause by killing the parasites. In addition, systemic medications can reach distant sites of infection However, there is no evidence that the parasite is actually living in ocular tissues and the inflammatory process may be directed against already dead parasite 3. Also, they may have side effects. Effectiveness depends on the specific type of trematode and its susceptibility to the chosen medication. Steroid Therapy is considered the gold standard treatment including topical steroids and periocular Injection of Triamcinolone) Advantages: Reduces inflammation in the eye. Provides symptomatic relief. Disadvantages: Does not address the underlying cause (parasitic infection)4. Prolonged or high-dose steroid use may lead to side effects, such as increased intraocular pressure or cataract formation. In resistant cases Surgery has been advocated by many authors Advantages: Surgical removal of nodules may be considered in specific cases. Can be beneficial in cases of severe complications, such as retinal detachment5. Disadvantages: Invasive procedure with associated risks and is mainly aimed at managing complications. Laser Therapy has been reported to destroy the pearl like nodules using Argon laser Potential damage to surrounding healthy tissue is the main drawback. Therefore, there is no consensus about the best line of treatment for this entity Rational for this study: Understanding the available treatment options is crucial for healthcare professionals involved in the care of patients with this condition7 ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
