Treatment of spontaneous corneal perforation secondary to undiagnosed Sjögren's syndrome using regenerating agent and autologous serum eye drops.

PURPOSE: The aim of this study was to report a case of sterile corneal ulcer leading to perforation, which was treated effectively with autologous serum eye drops, topical regenerative agent (poly-carboxymethylglucose sulfate), steroids, and systemic immunosuppression in a patient with undiagnosed primary Sjögren's syndrome. METHODS: A 74-year-old female presented with a month's history of gradually worsening blurry vision in her left eye. Ophthalmic examination revealed a central descemetocele with excessive corneal stromal melting and absence of signs of infection. A bandage contact lens was applied for tectonic support along with topical corticosteroid and antibiotic drops. Autoimmune screen disclosed a diagnosis of Sjögren's syndrome, and the patient was commenced on systemic immunosuppression. Forty-eight hours after presentation, the patient developed a localized corneal perforation, presenting with a flat anterior chamber. RESULTS: Urgent amniotic membrane transplantation was arranged while topical dexamethasone, moxifloxacin, and autologous serum eye drops were administered. After 24 h of intensive topical treatment, a significant reforming of the anterior chamber and subsequent gradual regeneration of the corneal stroma were noted, thus postponing amniotic grafting. The patient remained under close monitoring, showing progressive clinical improvement. Regenerating agent eye drops (Cacicol20®) were also applied over the next month, with careful and slow tapering of topical dexamethasone. Further improvement of corneal thickness was observed, and visual acuity increased to 20/80. CONCLUSION: This case report demonstrates the successful medical treatment of an autoimmune-related sterile corneal perforation without surgical intervention, highlighting the fact that early diagnosis and rigorous medical treatment with autologous serum and regenerating agent eye drops can effectively aid tissue regeneration and favorable visual rehabilitation.

Lamellar Keratoplasty Combined with Amniotic Membrane Transplantation for the Treatment of Corneal Perforations: A Clinical and In Vivo Confocal Microscopy Study.

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 = 13) was classified as infectious (n = 13) was classified as infectious (. 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.

Case Report: Evaluating Intraocular Foreign Bodies After Corneal Perforation Using Swept Source Anterior Segment Optical Coherence Tomography.

SIGNIFICANCE: Use of anterior segment optical coherence tomography (OCT) is reported, exploring its advantages over other examination techniques. PURPOSE: The purpose of this study was to report a case in which anterior segment OCT was used to evaluate the presence of intraocular bodies after corneal perforation. CASE REPORT: A 33-year-old man was referred to our ophthalmology department after traumatic ocular injury. Swept-source anterior segment was carried out showing corneal perforation and anterior lens capsule rupture. CONCLUSIONS: Evaluating the integrity of posterior capsule and iris after traumatic ocular injury with corneal perforation using anterior segment OCT is a valuable tool to rule out the presence of intraocular foreign bodies without contact and without using radiating imaging techniques.

Evaluation and Clinical Course of Keratomalacia With Descemetocele in a Child With Autism and Vitamin A Deficiency.

Autistic children with selective diets have an elevated risk for vitamin A deficiency. The authors present the case of a 7-year-old boy with keratomalacia resulting from dietary vitamin A deficiency. Optical coherence tomography and ultrasound biomicroscopy can provide useful details of the cornea and underlying structures. Vitamin A supplementation can result in significant resolution, obviating the need for surgical intervention. [J Pediatr Ophthalmol Strabismus. 2020;57:e1-e3.].

Mechanism of fluid leak in non-traumatic corneal perforations: an anterior segment optical coherence tomography study.

AIM: Non-traumatic corneal perforations (CPerfs) may present with shallow/flat or formed anterior chamber (AC). This study uses anterior segment optical coherence tomography (ASOCT) to ascertain these differences. METHOD: The study included 14 eyes of 13 patients. They underwent high-resolution ASOCT scans at multiple time points, prior to and after cyanoacrylate glueing, between January 2016 and July 2018. A retrospective analysis of over 2500 ASOCT sections and AS photographs was conducted by two independent observers. The findings were correlated with clinical features and diagnoses. RESULT: All patients had documented Seidel's positive sign at the outset. Two groups with distinctive features were identified. In group 1, 'formed' AC, there was hydration of the cornea with lamellar separation of the stroma, intrastromal pockets of fluid, epithelial bullae and an indirect communication between AC and the exterior. In group 2, 'flat' AC, the corneal hydration was less obvious, there were no pockets of intrastromal fluid, no epithelial bullae and a direct communication of the AC with the exterior. After glueing, the stromal hydration resolved, and healing occurred beneath the glue. The glue and corneal blood vessels consistently cast a dense shadow posteriorly on ASOCT. CONCLUSION: ASOCT demonstrates that leaking CPerfs can be indirect or direct. The former is associated with a 'formed' AC and the latter with a very shallow/flat AC. The valvular nature of the communication in indirect perforations allows the AC to maintain its volume despite a continuous leak.

Sclerocorneal graft and sequential removal of melted cornea after severe corneal burn with perforation.

Corneal burn grade IV usually leads to blindness. Several different surgical techniques remain challenging owing to the extensive tissue damage. Here, we introduce a novel technique with a 15 mm corneoscleral and limbal homologous graft combined with sequential autologous corneal removal ab interno, with a vitrectomy probe to save the anterior chamber angle. In vivo anatomy with optical coherence tomography is the surgical key. A large 15 mm sclerocorneal graft is sutured on top of the remainder of the destroyed cornea and sclera after removal of the epithelium and conjunctiva, with anterior synechiolysis if necessary, peripheral iridectomy and conjunctivoplasty. The recipient central corneal stroma is not removed, primarily to protect the anterior chamber angle. After three weeks, the collagenolytic central recipient corneal stroma can be removed with a small 23 g vitrectomy probe, respecting the lens and scleral spur. The corneoscleral graft remains clear under systemic and local immunosuppression. Intraocular pressure is well controlled because the anterior chamber angle is respected. Recurrent corneal erosions need close follow-up. Therapeutic soft contact lenses can support topical therapy. In cases of sclercorneal graft decompensation or rejection after 3-5 years, a new sclerocorneal graft (with limbal donation) seems to be superior to perforating keratoplasty without limbal stem cell transplantation. Repeated sclerocorneal grafts after severe corneal burn with limbal transplantation and maintenance of the complete anterior angle structure are a successful option for preventing blindness and achieving good visual acuity.

Management of severe and refractory Mooren's ulcers with rituximab.

PURPOSE: Management of severe and refractory Mooren's ulcers is challenging as it encompasses tectonic surgical treatment and aggressive immunosuppressive therapies. Efficacy of rituximab in the management of severe Mooren's ulcers has never been reported. METHODS: Five patients (six eyes) from the Cornea and External Disorders department at the Rothschild Ophthalmologic Foundation (Paris, France) were treated for severe Mooren's ulcer unresponsive to conventional treatments between 2008 and 2016. Conventional treatment included topical steroid and ciclosporin 2%, high doses of systemic corticosteroids and/or cyclophosphamide and conjunctival resection with amniotic membrane graft. These patients received two infusions of 1000 mg of rituximab at 2 weeks interval. Epithelial healing, inflammation, additional surgery, systemic corticosteroids and rituximab-related side effects were reported. RESULTS: The mean follow-up was 46.8 months. Following rituximab treatment, we observed a complete healing of Mooren's ulcer within 2 weeks in all patients. Peripheral lamellar keratoplasty was associated when peripheral corneal perforation occurred (5/6 affected corneas). Systemic corticosteroids had been discontinued in all patients. Two recurrences occurred 13 and 53 months after the first rituximab infusion and where successfully treated with a new infusion. No rituximab-related adverse events were reported. CONCLUSIONS: Rituximab was effective in the management of severe Mooren's ulcers and could be an alternative to cyclophosphamide. Additional studies should assess the role of this biotherapy in the management of immunological corneal ulcer.
