Results The patient showed bilateral diffuse, symmetric, non-polychromatic, punctiform crystals in all layers of the cornea. The remaining part of the ophthalmic clinical assessment was normal. Esthesiometry was normal in all quadrants. Anterior segment OCT confirmed diffused hyperreflectivity of the epithelium and corneal stroma. IVCM was then executed, showing polymorphic (granular, needle-like, stellate) hyperreflective crystals in all layers of corneal epithelium and anterior stroma, subbasal plexus nerves beading, cytoplasmatic hyperreflectivity of the keratocytes of the posterior stroma without any endothelial involvement After considering the age, health status, and ocular signs the primary entities to be investigated were adult benign cystinosis and paraproteinemic disorder. All the diagnostic tests were negative except for a monoclonal component IgG/k of 1.37 d/dl. A hematological examination was then performed with the resulting diagnosis of MGUS. In this paper, we analyzed 11 articles about IVCM in PPK in MGUS and other paraproteinemias highlighting IVCM features compatible with our findings allowing us to generalize a first diagnostic IVCM pattern for PPK. Conclusions In this case report we suggest the IVCM diagnostic patterns that may be used to identify PPK without corneal biopsy.","PeriodicalId":100782,"journal":{"name":"Journal of EuCornea","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136253817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods We present the case of a 25-year-old woman with poor light perception in both eyes who had bilateral chemical burn with caustic soda 3 months earlier. She underwent several amniotic membrane implants and subconjunctival triamcinolone injections without significant improvement. We decided to perform a two-stage surgery on the right eye (RE). Reconstruction of the ocular surface was first performed using a buccal mucosa allograft. Nine months later the second surgical stage was performed, which consisted of partial lifting of the buccal mucosa, B1-KPro implantation covered with the buccal mucosa overlay and exposing the optics of the keratoprosthesis. Results Two days following surgery the uncorrected visual acuity (UCVA) was +0.2 logMAR. Best-corrected visual acuity (BCVA) at one month was 0,0 logMAR, remaining stable after one year and eleven months of follow-up. Conclusions Boston type 1 keratoprosthesis covered with buccal mucosa (B1-KPro with mucosa overlay technique) could be considered an alternative in severe ocular chemical burn with marked shortening of the fornix, as an alternative to osteo-odonto-keratoprosthesis (OOKP) or tibial bone keratoprosthesis or when the Boston type II keratoprosthesis is not available. It allows restoration of the anatomy and condition of the ocular surface using autologous tissue, with better aesthetics than OOKP and material easily available as it has the CE marking.","PeriodicalId":100782,"journal":{"name":"Journal of EuCornea","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136240936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cyanoacrylate glue is a fast-acting and effective adhesive which has been utilised in the repair of corneal perforations.

A 26-year-old male patient with a history of herpetic keratitis was admitted to our clinic with a finding of approximately 1 mm corneal central perforation in his right eye. The best corrected visual acuities of right and left eyes were 2.3 and 0 logMAR, respectively. Anterior segment examination revealed corneal edema, vascularization, shallow anterior chamber and central corneal perforation in the melting area. No pathology of the retina or vitreous was detected in B-scan ultrasonography. Anterior and posterior segment examination of left eye was normal. Conventional approaches including bandage contact lens failed to buffer the leak. Since human corneal donor tissue was not available, fibrin glue application from inside to outside along the perforation area combined with AMT was applied. Even after 2 weeks when the amnion was degraded, it was observed that the perforation area was stable without any additional intervention. NK is one of the challenging reasons of corneal perforation. Although tectonic keratoplasty is the main treatment modality owing to transparency and high tissue resistance in the central corneal perforation repair, alternative treatment methods are necessary due to difficulty of access to donor cornea. Tissue adhesives and AMT are conservative methods to buffer leak with easier access. Present case clarifies the importance of alternative management modalities of corneal perforation in the absence of tectonic graft. Considering that only 1 donor cornea is available to 70 needed around the world, corneal perforation repair with fibrin glue combined with AMT seems wise.","PeriodicalId":100782,"journal":{"name":"Journal of EuCornea","volume":"81 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83917195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The drug-resistant strain was later traced to use of contaminated EzriCare Artificial Tears in a multi-state cluster outbreak. A 57-year-old male patient with a history of Descemet stripping automated endothelial keratoplasty was referred for a culture-positive Pseudomonas corneal ulcer in the right eye that had been treated with several weeks of topical moxifloxacin, fortified vancomycin and tobramycin, and intravitreal injections for endophthalmitis. His cornea was cultured off of antibiotics and grew only rare Propionibacterium acnes. Topical antibiotics and steroids were reduced, but his condition rapidly deteriorated with leading to corneal melt, perforation, and endophthalmitis. Repeat corneal cultures and sensitivity analyses revealed growth of a strain of Pseudomonas aeruginosa that was resistant to fluoroquinolones, aminoglycosides, cephalosporins, monobactams, and carbapenems, and only intermediate susceptibility to piperacillin-tazobactam. The patient underwent a therapeutic penetrating keratoplasty and was subsequently initiated on an intensive regimen of topical chlorhexidine and polymyxin-B/trimethoprim. He also underwent a pars plana vitrectomy with anterior chamber washout, followed by serial injections of intravitreal piperacillin-tazobactam at a dose of 225 mg/0.1 mL. After 8 weeks of intensive treatment, there was gradual with healing of his ocular surface, regression of his hypopyon and posterior inflammation, and no signs of recurrent infection. A public health investigation ultimately revealed that his infection was one of several cases involved in a multistate cluster outbreak of extensively drug-resistant Pseudomonas ocular infections that were traced to the use of contaminated EzriCare Artificial Tears. Multidrug-resistant keratitis and endophthalmitis caused by multidrug-resistant Pseudomonas keratitis requires consideration of nonconventional antimicrobial agents and experimental therapeutic alternatives. Topical chlorhexidine and intravitreal piperacillin-tazobactam are currently nonconventional therapies in the context of bacterial keratitis and endophthalmitis, but were safe and effective in the management of multidrug-resistant Pseudomonas aeruginosa ocular infection.","PeriodicalId":100782,"journal":{"name":"Journal of EuCornea","volume":"2013 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86269007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 65/F presented with blindness, OS from glaucoma but with a clear cornea, and corneal decompensation with cataract in OD with good visual potential. Heterotopic autokeratoplasty was performed due to the scarcity of corneal allografts and the high-risk nature of the case, with ECCE and IOL implantation in OD due to lens opacity. Temporary keratoprosthesis (TKP) (such as Eckardt and Landers models) was substituted with RGP due to lower cost and accessibility. Pre-placement of two polyglactin perpendicular mattress sutures in the episclera at the horizontal and vertical positions was done and left untied. Next, left corneal trephination was performed using an 8-mm vacuum trephine, followed by the instillation of oculoviscosurgical device (OVD) and placement of a 10-mm diameter RGP lens over the left open globe, secured in place by tying the pre-placed overlying cross sutures. Then, right corneal trephination using a similar-sized trephine proceeded. Cataract was extracted in open-sky technique with IOL in the bag implantation. The clear left corneal button was then transplanted to OD and vice-versa. Postoperatively, VA improved from hand motions to 10/200 (Day 1). The graft remained clear 4 weeks post-op with further improvement in VA. IOP was maintained below 15 mmHg. Heterotopic autokeratoplasty is a valid option for unilateral cornea blind patients who have clear corneas in the fellow eye with no visual potential. This is useful in countries where corneal transplantation is costly, especially during time of pandemic when corneal allografts are scarce. In our experience, it can be safely performed using an RGP lens as a safe and cost-effective alternative to temporary keratoprosthesis.","PeriodicalId":100782,"journal":{"name":"Journal of EuCornea","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87192734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is a retrospective comparative clinical cohort study. Thirty eyes with clinically suspected and lab-confirmed severe fungal keratitis with ongoing corneal melting were included. These eyes were classified randomly into two groups each of 15 eyes. In group (A), all the eyes underwent repeated sessions of M-CXL with frequent instillations (FI) of topical voriconazole each week till the reversal of corneal melting, then intrastromal injections of voriconazole were added each week till complete corneal healing together with negative culture on lab examination. In group (B), all the eyes underwent repeated intrastromal injections of voriconazole each week together with frequent instillations (FI) of topical voriconazole till complete corneal healing with negative culture on lab examination. Identification of organisms was done by lab study before and after treatment. Corneal healing was evaluated by corneal examination and anterior segment OCT (AS-OCT). Successful treatment was reported in 13 eyes (86.7%) of group (A), while in group (B), successful treatment was reported in 9 eyes (60%), while failure of treatment with complications was reported in 2 eyes (13.3%) in group (A) , however, in group (B), failure of treatment with complications was reported in 6 eyes (40%), with statistically significant difference (p <0.05) between the two groups. Visual improvement was observed in group (A) more than group (B). M-CXL followed by intrastromal injection of voriconazole was found to be effective in treating severe fungal keratitis with ongoing corneal melting due to the known action of CXL for reversal of corneal melting and anti-infective properties. Our results revealed that combined M-CXL and intrastromal injection of voriconazole was safer than intrastromal injection of voriconazole alone for treating severe fungal keratitis with corneal melting with better visual outcomes.","PeriodicalId":100782,"journal":{"name":"Journal of EuCornea","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79438197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
