Background: The aim of the work is a discussion of amniotic membrane transplantation at the Eye Clinic of the University Hospital Brno and a retrospective evaluation of a group of patients for the period 2014–2019 who were treated for various indications.

Methods: Retrospective evaluation of the number and effectiveness of individual types of amniotic membrane in a group of patients after amniotic membrane transplantation (AMT) for various indications. A total of 134 patients were included in the study group, of which 68 were men and 66 were women. The median age was 70 years. The total number of amniotic membrane transplants performed during the selected six years was 139, with half the distribution using frozen (69 eyes) and lyophilized amniotic membrane (70 eyes). The AMT technique was chosen based on the initial finding and diagnosis. The type of amniotic membrane used (lyophilized vs. frozen) depended on the urgency of the procedure.

Results: The number of amniotic membrane transplantations was evaluated in a group of 134 patients (139 eyes) and their effectiveness in individual diagnoses was demonstrated. During the follow-up period, more transplantations of amniotic membranes were performed during hospitalization than in the outpatient department, both types of membranes (frozen and lyophilized). Amniotic membrane transplantation during hospitalization was performed in 89 eyes, in the outpatient mode in 50 eyes. Indications for amniotic membrane transplantation included microperforation and corneal perforation (30 eyes), non-healing corneal defects (21 eyes), descemetocele (19 eyes), neurotrophic defects (16 eyes), ablation of pterygium (12 eyes) and corneal lysis (11 eyes). eyes). Other conditions (conjunctival lesions, fornix reconstruction, burns, peripheral ulcerative keratitis, ocular cicatricial pemphigoid and keratectomy) were represented in smaller numbers. Despite the very diverse group of indications and the advanced age of the patients, a very good efficacy of the performed amniotic membrane transplantations was found. Some patients died during the follow-up period, so the limitation of work is short and unequal follow-up period.

Conclusion: The success of the procedure depends not only on the correct timing, indication and technique of transplantation, but also on patient compliance and well-functioning cooperation of regional ophthalmologists.
