A etrospective review of patients who underwent tenon patch graft sutured with 10.0 monofilament to the cornea, the limbus or conjunctiva, to seal corneal perforation, whatever its origin, the indications of surgery were any patient presenting a corneal perforation larger than 3mm, or smaller with iris prolapse. from February 2020, to September 2021, the success of the procedure is defined by the formation of a corneal scar, the absence of corneal staging by fluorescein, and formation of the anterior chamber

The follow up is carried out by slit lamp examination and anterior segment OCT.

49 eyes of 49patients were operated, The mean age was 56.2 (5 to 89) years old, with 29 male and 20female patients. The etiologies are infectious keratitis (n=32), trauma (n=5), peripheral ulcerative keratitis (n=7), neurotrophic keratitis (n=4), chemical burns (n=1).

The mean BCVA was 1,5 LogMAR. The mean size of corneal perforation was 3,9mm (3 to 4.5mm), the site was central (n=32, 65.3%), paracentral (n=10, 20.4%), or peripheral (n=7, 14.28%). The IOP was low digitally in all the case preoperatively.

48 healed completely, with mean duration of scar formation of 8,1 weeks, the BCVA after complete healing of cases was 1.8 LogMAR

Tenon patch graft is a promising technique, simple and inexpensive in the management of corneal perforations in the event of the unavailability of other therapeutic techniques and especially during the lockdown accompanying COVID 19, in order to preserve the morphology of the eyeball and to prepare for keratoplasty

Anterior segment OCT is a an excellent tool of monitoring the progress of corneal perforations after their surgical management.
