Brief Summary

Ophthalmology ,cornea Autologous serum has long been known to be effective to promote corneal epithelial wound healing in a variety of ocular surface disorders. However, its effectiveness for corneal epithelial defects due to pars plana vitrectomy (PPV) for diabetic retinopathy and penetrating keratoplasty has seldom been reported. In this study, we plan to perform a prospective study to determine the effectiveness of topical autologous serum as a primary treatment for corneal epithelial defect in patients undergoing vitrectomy for diabetic retinopathy and penetrating keratoplasty. All patients enrolled in this study have received corneal epithelial debridement at the end of the ocular surgeries, namely PPV for diabetic retinopathy and penetrating keratoplasty. The patients were grouped into two treatment groups. In the control group, the patients receive conventional postoperative eye drops including topical steroid, antibiotic and mydriatics. In the experimental group, the patients receive topical autologous serum eye drops in addition to conventional postoperative eye drops. The duration for cornea surface to completely re-epithelize, the incidence of corneal complications due to delayed surface re-epithelization (e.g. infectious corneal ulcer, corneal melting, sterile corneal ulcer, corneal neovascularization), and the incidence of recurrent epithelial break down after initial epithelization will be compared between these two groups. Patients undergoing PPV for diabetic retinopathy and penetrating keratoplasty will be compared separately

Outcome Measures

Primary Outcomes (1)

  • Patients With Corneal Epithelial Healing Time Within 14 Days

    Patients were hospitalized and examined daily for graft re-epithelialization, which was the main outcome measure.Corneal epithelial healing(the process which the new corneal epithelial cells regenerated to cover the bare cornea lost of its epithelium, the cornea's outer layer) was recorded daily by slit-lamp examination with fluorescein staining.Patients with post-operative chronic persistent epithelial defects for \>14 days after the operation were treated with therapeutic contact lens (TCL) application and followed up as outpatients.

    every day till total re-epithelization up to 14 days

Secondary Outcomes (1)

  • Patients With Corneal Complications Due to Delayed Surface Re-epithelization (e.g. Infectious Corneal Ulcer, Corneal Melting, Sterile Corneal Ulcer, Corneal Neovascularization)

    every day till total re-epithelization up to 14 days

Study Arms (2)

Autologous serum use

ACTIVE COMPARATOR

Patients treated with additional 20% autoserum after diabetic vitrectomy or penetrating keratoplasty

Other: autologous serum

Non-autologous serum use

PLACEBO COMPARATOR

Patients treated with traditional medication(0.1% betamethasone, 0.3% gentamicin and 0.4% tropicamide eye drops application 4 times daily) after diabetic vitrectomy or penetrating keratoplasty

Other: Non-autologous serum

Interventions

with postoperative 20% autologous serum diluted with preservative-free artificial tear application bi-hourly during waking hours

Also known as: Autoserum
Autologous serum use

without postoperative 20% autologous serum diluted with preservative-free artificial tear application bi-hourly during waking hours

Non-autologous serum use

Eligibility Criteria

Age20 Years - 70 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • patients with proliferative diabetic retinopathy who's condition need to receive pars plana vitrectomy or patients who need to receive penetrating keratoplasty

You may not qualify if:

  • For PPV: ocular disease such as limbal stem cell Insufficiency , glaucoma, lagophthalmos
  • For penetrating keratoplasty:ocular or systemic disease that would affect epithelial healing, such as severe dry eye, severe lid abnormalities, limbal stem cell deficiency, or corneal anesthesia
