Detailed Description

Vernal keratoconjunctivitis (VKC) is an allergic disease that severely affects the eyesight of adolescents. Vernal keratoconjunctivitis (VKC) usually occurs in temperate regions such as the Mediterranean region, the Middle East, Africa, Central America, and the Indian subcontinent. In the EU an estimated 3.2 per 10,000 inhabitants (0.03%). It occurs repeatedly and mainly involves type I and type IV hypersensitivity. long-term standardized treatment is necessary. Therefore, this research aims to compare the readily available cyclosporine 0.05% eye drops and Loteprednol Etabonate 0.5% and Tobramycin Eye Drops 0.3% in developing regions of Asia (China, Jiangxi Province) for long-term drug use in VKC patients in developing countries provide evidence.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: Cyclosporine 0.05% eye drops group
The patients with VKC will receive Cyclosporine 0.05% eye drops or Loteprednol Etabonate 0.5% and Tobramycin Eye Drops 0.3% effect of Cyclosporine 0.05% eye drops would be evaluated during the follow-up visits.
Drug: Cyclosporine 0.05% eye drops
Use of 0.05% CSA could significantly reduce IL-4, IL-5, IL-17A, and TNF in tears of VKC patients- α、 IFN- γ And eosinophil chemokine levels. Cyclosporine A (CSA) can effectively control ocular inflammation by blocking Th2 lymphocyte proliferation and IL-2 production. It can also inhibit the recruitment of eosinophils by inhibiting the release of histamine by mast cells and reducing the production of IL-5 further to improve its curative effect on VKC
Drug: Loteprednol Etabonate 0.5% and Tobramycin Eye Drops 0.3%
Corticosteroids can inhibit the release of mast cells, block the chemotaxis of inflammatory cells, and reduce the number of mast cells and eosinophils in the conjunctiva. At the same time, it can inhibit phospholipase A2 and quickly alleviate symptoms and signs.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Changes of ocular signs
Time Frame: Day 0#7#15#30 and 60d
The eye signs of the patients were observed under a slit lamp, including Conjunctival Hyperemia, Tarsal papillary, Limbal hypertrophy, Horner-Trantas dots, and Keratitis in some patients.The observer gives the corresponding score.The higher the score, the more serious it is (0-4 points)
Day 0#7#15#30 and 60d
Changes of self-conscious symptoms
Time Frame: Day 0#7#15#30 and 60d
The VAS scoring table was used for the patients' self-conscious symptoms, including pruritus, foreign body sensation, Photophobia and tears, and viscous secretions. The patients under study were self-scored at each review. 0-100 points, 0 indicates no discomfort, and 100 indicates the most significant pain. The intraocular pressure at each review was recorded by a non-contact tonometer.
Day 0#7#15#30 and 60d
