Abstract

fetched live from OpenAlex

PURPOSE: To describe the presentation and management of 2 cases of Descemet stripping automated endothelial keratoplasty (DSAEK) with failure secondary to cytomegalovirus (CMV) infection and prophylaxis with topical ganciclovir to prevent repeat failure of Descemet membrane endothelial keratoplasty (DMEK) regrafts. METHODS: A retrospective chart review was conducted for 2 patients with DSAEK failure secondary to CMV infection. RESULTS: A 70-year-old immunocompetent man (case 1) and a 53-year-old immunocompromised man (case 2) received DSAEK for presumed pseudophakic bullous keratopathy and endothelial decompensation secondary to recurrent uveitis, respectively. Case 1 had first graft failure at 10 months and case 2 at 21 months with inferior edema and keratic precipitates. Both failed to respond to topical steroid drops, and case 1 had 3 subsequent failed DSAEKs. Anterior chamber paracentesis confirmed CMV DNA. Neither had a clinical response to 6 weeks of oral valganciclovir. They were then administered topical ganciclovir (0.15% ophthalmic gel), and repeat endothelial transplant (DMEK) was performed for both patients. They were again administered topical ganciclovir 4 times daily after surgery because aqueous samples remained positive for CMV. Both remain free of inflammation or failure on topical ganciclovir for 21 months (case 1) and 29 months (case 2) with uncorrected visual acuities of 20/40 and 20/25, respectively. CONCLUSIONS: Long-term topical ganciclovir use can prevent recurrence of CMV-associated graft failure even in immunocompromised hosts without side effects of systemic antivirals. DMEK may have advantages over DSEK in eyes with previous CMV infection and in eyes prone to inflammation.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
