NCT05320172

Brief Summary

The Aim of the study is to evaluate the efficacy of platelet rich plasma eye drops in the management of different corneal surface disorders. PRP is a blood sample with a concentrated platelet count, and numerous growth factors that are associated with conjunctival and corneal wound healing process. which is an important advantage over other products. PRP eye drops recently are proving to be an effective and potent therapeutic approach to promote corneal wound re-epithelization and promote ocular surface regeneration in different pathological conditions.

Outcome Measures

Primary Outcomes (3)

  • Evaluation of the efficacy of platelet rich plasma eye drops in the management of persistent corneal epithelial defects, and dry eye disease by observation of change in size of defect over different periods of time.

    To evaluate the effect of platelet-rich plasma (PRP) eye drops in management of different ocular surface pathologies, the therapeutic response will be evaluated with clinical examination and follow up. Main outcome measurements include the change in size of defect by fluorescein staining on slit lamp biomicroscopy. The largest linear dimension of the epithelial defect and its largest possible perpendicular within the confines of the epithelial defect are measured in millimeters using a slit lamp.

    At 48 hours, one week and one month.

  • Evaluation of the efficacy of platelet rich plasma eye drops in the management of persistent corneal epithelial defects, and dry eye disease by observation of change in visual acuity.

    To evaluate the effect of platelet-rich plasma (PRP) eye drops in management of different ocular surface pathologies, the therapeutic response will be evaluated with clinical examination and follow up. Main outcome measurements include the change in visual acuity measured by Snellen visual acuity (VA) testing.

    At 48 hours, one week and one month.

  • Evaluation of the efficacy of platelet rich plasma eye drops in the management of persistent corneal epithelial defects, and dry eye disease by observation of change in height of tear meniscus,

    To evaluate the effect of platelet-rich plasma (PRP) eye drops in management of different ocular surface pathologies, the therapeutic response will be evaluated with clinical examination and follow up. Main outcome measurements include the change in height of tear meniscus measured by slit lamp biomicroscopy.

    At 48 hours, one week and one month.

Secondary Outcomes (1)

  • Evaluation of the efficacy of platelet rich plasma eye drops in the relief symptoms caused by persistent corneal epithelial defects, and dry eye disease by observation of change in ocular symptoms.

    At 48 hours, one week and one month.

Study Arms (1)

Treatment group

EXPERIMENTAL

Participants with persistent epithelial defects will be treated with autologous platelet rich plasma eye drops.

Drug: Autologous platelet rich plasma eye drops

Interventions

Fifty milliliters of patient's own whole blood will be placed in five 10-ml vacutainer tubes containing anticoagulant-citrate-dextrose solution (1.4 ml) and centrifuged at 200g for 11 min. The upper two layers of the centrifuged blood, the plasma and buffy coat layer will be separated in a sterile manner and diluted to 20 % (v/v) with a sterile saline solution. The final preparation is divided into 5-ml bottles wrapped in aluminum foil for protection from ultraviolet light. The patients are instructed to store these bottles at -20 °C until required. The bottles being used will be maintained under refrigerated conditions at 4 °C.
