Sclera to the Rescue in the Covid-19 Pandemic- Therapeutic Scleral Grafting in Perforated Corneal Ulcers due to Donor Cornea Shortage

The present article describes the penetrating keratoplasty using the technique of rehydration of donor cornea dehydrated over silica gel, as well as complications that can arise. The indications included corneal ulcers, descemetocoele, corneal sequestrum and corneal perforation. 37 (88.37%) out of 43 corneal transplants had a favorable outcome in surgeries with complete excision of abnormal tissues. In 5 cases (11.63%), the authors faced such complications as suture failure, formation of anterior synechias, incomplete epithelization after the suture removal, and transplant swelling reversed with the preservation of eye optical functions, and secondary glaucoma in the late postoperative period that ended up in eyeball endoprosthesis transplantation. Due to a high rate of efficiency of the proposed method, penetrating keratoplasty with rehydrated grafts can be recommended for the treatment in case of medical emergency experienced by cats and dogs.

The Mean

This study aimed to investigate the use of Plasma Rich in Growth Factors (PRGF) associated with tissue ReGeneraTing Agent (RGTA) drops for the treatment of noninfectious corneal ulcers. RGTA treatment was applied (one drop every two days); however, if ulcer closure was not achieved, PRGF eye drops treatment was added (four times/day). The time taken to reach the ulcer closure, the Best Corrected Visual Acuity (BCVA), intraocular pressure (IOP), Visual Analog Scale (VAS, in terms of frequency and severity of symptoms), and Ocular Surface Disease Index (OSDI) were evaluated. Seventy-four patients (79 eyes) were included, and the mean age was 56.8 ± 17.3 years. The neurotrophic corneal ulcer was the most frequent disorder (n = 27, 34.2%), mainly for herpes virus (n = 15, 19.0%). The time of PRGF eye drops treatment associated with the RGTA matrix was 4.2 ± 2.2 (1.5–9.0) months, and the follow-up period was 44.9 ± 31.5 months. The ulcer closure was achieved in 76 eyes (96.2%). BCVA, VAS and OSDI improved from the baseline (p < 0.001), and IOP remained unchanged (p = 0.665). RGTA and PRGF in noninfectious ulcers were effective and could be a therapeutic alternative for this type of corneal disease.
