Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this study Investigators are going to do early amniotic membrane transplantation (AMT) for bacterial keratitis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this study investigators are going to do amniotic membrane transplantation (AMT), early in the first week for bacterial keratitis. Investigators are comparing this technique with no amniotic membrane transplantation (NAMT) in a clinical trial, Inform consent is going to be taken, then the enrolment population is added in the study. Investigators are going to compare the final scar size, the time to scar formation, perforation rate , early need to penetrating keratoplasty (PKP), risk of vision loss (being no light perception (NLP) between two groups.This trial has been approved by the review board in Tehran University of Medical Sciences.( 487/5671)

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Non AMT

Freshly prepared fortified eye drops (cefazolin 50 mg/mL and amikacin 14 mg/mL) were applied as starting treatment. In the first 3 days, eye drops are applied round the clock followed by drops every 2 h during waking hours until results of laboratory investigation were available.

After preparation of the culture results, the antimicrobial treatment was narrowed according to bacterial sensitivity. Also topical betamethasone 0.1% four times a day on a tapering weekly dosage until 3-4 weeks is used for all patients. If the patient underwent any tectonic procedure during the treatment such as keratoplasty, cyanoacrylate glue are documented

Group Type NO_INTERVENTION

No interventions assigned to this group

AMT

This group (case group) received above mentioned routine antibiotic therapy followed by double-layer amniotic membrane transplantation 2-5 days after the start of medications and the second group (control group) only received routine antibacterial therapy.

The AM was trimmed in two layers to fit the corneal ulcer and was placed with its epithelium (basement membrane) side up, secured with 10/0 nylon sutures, supported by a therapeutic contact lens. If the patient underwent any tectonic procedure during the treatment such as keratoplasty, cyanoacrylate glue are documented.

Group Type ACTIVE_COMPARATOR

AMT

Intervention Type PROCEDURE

The AM was trimmed in two layers to fit the corneal ulcer and was placed with its epithelium (basement membrane) side up, secured with 10/0 nylon sutures, supported by a therapeutic contact lens. The operated eye was patched for 2 h, and then administration of the medical treatment agents was resumed.

In patients in the case group AMT was performed during days 2-5 of antibiotic therapy when initial clinical response to the treatment was observed.
