Letter Regarding: Establishing a Biomarker for the Prediction of Short-Term Graft Detachment After Descemet Membrane Endothelial Keratoplasty
No full textImportance of Corneal Angiography in Subclinical Limbitis in a Case of Atopic Keratoconjunctivitis
No full textPurpose: The aim of this study was to report corneal angiography features in subclinical limbitis in a patient with atopic keratoconjunctivitis. Methods: This is a case report. Results: A 22-year-old woman with a medical history of atopic keratoconjunctivitis was referred for bilateral corneal neovascularization with scarring. On examination, no signs of active disease were noticed at the slit lamp. Ocular surface angiography detected active corneal limbitis, showing as limbal leakage at fluorescein angiography in the early phase and leakage after indocyanine green angiography in the late phase. The patient was treated with topical corticosteroid. At follow-up, the fluorescein angiography and indocyanine green angiography no longer showed limbal leakage, whereas the slit lamp examination was unchanged. Conclusions: Active allergic corneal limbitis may present as subclinical inflammation, with no signs of activity at the slit lamp examination. Therefore, its diagnosis can be challenging without the use of corneal angiography
Blast Wound Dehiscence During Descemet Membrane Endothelial Keratoplasty Rebubbling in a Previous Penetrating Keratoplasty: A Case Report
No full textPurpose: The purpose of this study was to describe a rare complication of Descemet membrane endothelial keratoplasty (DMEK) rebubbling. Methods: An 86-year-old woman with bilateral penetrating keratoplasty (PK) performed 20 years previously for Fuchs endothelial dystrophy underwent DMEK surgery for endothelial corneal decompensation in the left eye. Surgery was complicated in the postoperative period by repeated DMEK graft detachments requiring rebubbling. Results: The third rebubbling procedure caused a traumatic PK wound dehiscence at the graft-host junction with full-thickness opening of approximately 180 degrees. PK wound dehiscence was resutured in the theater, DMEK lenticule was removed from the eye, and the full-thickness graft was repeated. Conclusions: DMEK graft rebubbling in patients with previous PK may lead to traumatic wound dehiscence. Avoidance of excessive increases in intraocular pressure during the rebubbling procedure should be encouraged to decrease the risk of this rare complication

Searching for Stephen Crane: The Schoberlin Collection
No full textThis article meticulously recounts the building of the Schoberlin collection, which sought to gather material written by the American novelist Stephen Crane. The task was quite formidable, as competing collectors tried to beat each other to primary sources. The article also points out facts and discrepencies that the sources contain, giving a complex but interesting story about the ill-fated author
Descemet membrane endothelial keratoplasty graft detachments in superior versus temporal approach
No full textPurpose: To evaluate the difference in Descemet Membrane Endothelial Keratoplasty (DMEK) graft detachment rate comparing superior versus temporal main incision approach. Methods: Retrospective comparative study on patients who underwent DMEK surgery for Fuchs endothelial dystrophy or bullous keratopathy with main wound incision performed at either 90° in the superior approach, or at 180°/0° in the temporal approach. All main incisions were secured with a single 10-0 nylon suture at the end of surgery. Data collected were donor age and gender, endothelial cell counts, graft diameter, recipient age and gender, indication for transplant, surgeon grade, re-bubbling rate, air fill in the anterior chamber (AC) at day one and intra- and early postoperative complications. Results: 187 eyes were included in the study. 99 eyes had DMEK surgery with superior approach, while 88 eyes had temporal approach. The two groups had no differences in donor age and sex, endothelial cell counts, graft diameter, recipient age and sex, indication for transplant, surgeon grade, and air fill in the anterior chamber at day one. Re-bubbling rate was 38.4% for surgeries performed with superior access and 29.5% for those with temporal access(p = 0.186). After exclusion of patients with intraoperative and/or postoperative complication, the difference in re-bubbling rate was higher, although non-significant (37.5% and 25% for superior and temporal approach respectively, p = 0.098). Conclusion: The temporal approach in DMEK showed a trend towards a clinically significant lower rate of post-operative re-bubbling compared to the superior approach, however, no statistically significant difference was noted comparing the two approaches, which both remain feasible options in DMEK surgery

Novel Technique for Descemetorhexis Under Ophthalmic Viscosurgical Devices and Air
No full textPURPOSE: The aim of this study was to describe a novel technique for descemetorhexis that combines the advantages of stable anterior chamber (AC) associated with ophthalmic viscosurgical devices and optimal surgical visualization seen with air to overcome the issues of poor Descemet membrane (DM) visibility or AC instability when each is used alone. METHODS: This study is a description of a new surgical approach. RESULTS: We describe a new technique for performing descemetorhexis. The simultaneous presence of cohesive ophthalmic viscosurgical device and air in the AC offers optimal DM visualization and guarantees a stable AC during this surgical step. It does not require an additional incision for an AC maintainer. CONCLUSIONS: The described technique may facilitate the surgical step of descemetorhexis, offering improved AC stability and better visualization of the DM. It may reduce early postoperative graft detachment due to the presence of residues of the recipient's diseased DM
