Purpose. To report the use of infliximab in the rapid stabilization of a case of progressive, bilateral rheumatoid peripheral ulcerative keratitis (PUK) that failed to respond to conventional immunosuppressive therapy.Methods. A single interventional case report.Results. A patient with rheumatoid arthritis presented with bilateral PUK following a 2-month history of ocular discomfort and redness. His systemic prednisolone (PDN) and methotrexate (MTX) were increased and, despite an initial favorable response, bilateral recurrent corneal perforations ensued. Both eyes underwent cyanoacrylate glue repair, amniotic membrane transplantation (AMT), and penetrating keratoplasty (PKP). Recurrence of the disease and bilateral perforations of the second PKP in both eyes prompted administration of intravenous infliximab immediately after the fourth PKP. The disease activity rapidly settled in both eyes, and at eighteen-month followup, after 12 infliximab infusions, the PUK remains quiescent with no further graft thinning or perforation.Conclusion. Infliximab can be used to arrest the progression of severe bilateral rheumatoid PUK in cases that are refractory to conventional treatment.

Corneal Hydrops

Acute corneal hydrops is a pathological condition which clinically presents by marked corneal edema developing due to a break in Descemets membrane. Background. To analyze the results of diagnosis and treatment in patients with acute corneal hydrops. Materials and methods. 42 patients (47 eyes) suffering from acute corneal hydrops were included in the study. This condition appeared on both eyes simultaneously or sequentially in 5 patients. Mean age was 28.7 10.1 years (from 19 to 54 years), 31 men, 11 women. In case of complications or inefficacy of medical therapy surgical procedures were performed: 10% gas (C3F8, SF6) injection into the anterior chamber, amniotic membrane transplantation, partial lamellar keratoplasty, DALK, PKP. Results. Duration of corneal ectasia before acute hydrops occurrence was 12.6 4.6 years. Disease was not diagnosed before in 11.9%. Corneal thickness varied from 692 98 m in focal hydrops to 1200 220 m in total hydrops. Area of edema, height of Descemet detachment and gap between break margins were significantly above in cases of subtotal and total hydrops compared with focal and partial hydrops (2, p 0,001). Injection of 10% gas (C3F8, SF6) in the anterior chamber allowed to significantly accelerating the resolution of this condition in cases of subtotal and total hydrops. Conclusion. Analysis of this case series showed the feasibility of a differentiated approach in the treatment of acute corneal hydrops depending on its severity.

A New Technique

Abstract Background: conjunctival nevi are benign ocular lesions with a low risk of malignant transformation to melanoma. Due to cosmetic reasons patients usually consider surgical removal options. In this case report, we are presenting a new approach using plasma-assisted noninvasive surgery (PANIS) with amniotic membrane transplantation (AMT) to sublimate the nevus border and fuse the AMT with the remaining conjunctiva.Case presentation: A 33-year-old man with a history of large conjunctival nevus in his left eye, that its benignity was proved by an expert ophthalmologist through years of examination, has visited our center in September 2020. Plasma spots were used to sublimate the nevus border and fuse AMT with the conjunctiva. The patient was discharged fully satisfied without any complications and no recurrences were seen in a year of follow-up. Visual parameters were not significantly changed while the Ocular Surface Disease Index (OSDI) was reduced dramatically. Conclusion: Conjunctival nevi removal using the PANIS method with AMT is a safe, minimally invasive, and inexpensive therapeutic option. Plasma spots are suitable for AMT adhesion to the remaining conjunctiva after the nevus removal.

The Mean

Purpose. To evaluate the clinical and in vivo confocal microscopy outcome of lamellar keratoplasty combined with amniotic membrane transplantation for the treatment of corneal perforations. Methods. In this retrospective, noncomparative, and interventional case series, 13 eyes of 13 patients with corneal perforation were included. All eyes were treated with lamellar keratoplasty combined with amniotic membrane transplantation for corneal reconstruction. Age, underlying etiology, location, size of corneal ulcer, size of corneal perforation, hospitalization days and follow-up time, and corneal confocal microscopy were investigated. Aqueous leakage, anterior chamber formation, epithelial healing time, and visual acuity (VA) were monitored after operation. Results. The cause of corneal perforation (n = 13) was classified as infectious (n = 1) and noninfectious (n = 12). Most of the locations of corneal perforation were paracentral, and 2 of them were center. The anterior chambers were formed without aqueous leakage and other complications at postoperative day. The mean time of regained a smooth corneal surface was 7.5 ± 2.9 (ranging from 4 to 14) days. The mean hospitalization day was 13.1 ± 4.5 (ranging from 7 to 22) days. The mean follow-up time is 22.5 ± 14.5 (ranging from 4 to 43) months. The AM appeared as a high-reflective reflection in the corneal stroma after surgery about half a year and is almost transparent at about one year. Corneal stroma-derived cells were populated in the AM at about 1 month, increased at 2 months, and almost not obviously at 20 months postoperatively. The size and density of endothelial cells were stable after 1 year near the perforation site. The VA improved to varying degrees in 9 eyes, remained unchanged in 2 eyes, and decreased in 2 eyes. One eye recurrence and no side effects occurred during the follow-up time. Conclusion. Lamellar keratoplasty combined with amniotic membrane transplantation may be an alternative, safe, and effective surgical therapy in the treatment of corneal perforations in the absence of a fresh donor cornea. We recommend this surgery to treat with the size of corneal perforation of <4 mm in diameter no matter peripheral or central corneal perforation, especially who had immune-related diseases.

Shunt Implantation

Traditional options in managing failed trabeculectomy (bleb needling, revision, additional incisional surgery and tube surgery) have a relatively high failure and complication rate. The use of microinvasive glaucoma surgery (MIGS) has generally been reserved to mild to moderate glaucoma cases, proving good safety profiles but significant limitations in terms of efficacy. We describe a patient who underwent MIGS (XEN Aquesys subconjunctival shunt implantation) after a prior failed trabeculectomy. After the surgery, the IOP was well controlled but as the stent was close to an area of scarred conjunctiva of the previous trabeculectomy, it became partially exposed. As a complete success was achieved, we decided to remove the conjunctiva over the exposed area and replace it by an amniotic membrane transplantation and a conjunctiva autograft. Six months after surgery, the unmedicated IOP is still well controlled with complete visual acuity recovery.
