全植床深板層角膜移植術(shù)后角膜透明性變化及其與基質(zhì)細(xì)胞重構(gòu)的關(guān)系
[Abstract]:OBJECTIVE: Full-bed deep lamellar keratoplasty (FBDLK) is an innovative technique for deep lamellar keratoplasty. It can successfully expose the posterior elastic membrane of the recipient cornea by matrix hooking combined with viscoelastic separation. As transplantation materials, we have confirmed the clinical value of FBDLK surgery, but the problem of transparency change and cell component remodeling of this edematous acellular graft after FBDLK remains to be solved. Further study on this issue will provide a more powerful theoretical basis for the popularization and application of this new technique. The changes of corneal transparency and the process of stromal cell remodeling after FBDLK were evaluated.
Methods: From February 2002 to October 2009, 133 patients (141 eyes) underwent FBDLK surgery in the Ophthalmology Department of Shaoyou Hospital, Zhejiang University. Primary preoperative diseases included keratoconus (n = 56 eyes), keratoleukoplakia after herpes simplex keratitis (n = 41 eyes), corneal leukoplakia after trauma (n = 25 eyes) and corneal degeneration (n = 19 eyes). All patients were followed up 2 days, 7 days, 0.5 months, 1 month, 3 months, 6 months, 12 months and 24 months postoperatively. The changes of corneal transparency were observed and slit lamp photographs were recorded. Ultrasound corneal thickness and confocal microscopy were performed at 0.5, 1, 3, 6, 12 and 24 months postoperatively. Thickness changes were observed and analyzed by slit lamp microscopy, including corneal edema and opacity, anterior (25%), middle (50%) and posterior (25%) stroma Haze (non-edematous stroma opacity) and interface opacity of implant bed. Confocal microscopy was used to observe the morphology of corneal stroma with disordered acellular reflector and stromal cells. Finally, the relationship between Haze and the remodeling of stromal cells was studied by slit lamp microscopy and confocal microscopy.
Results: The average epithelialization time of frozen preserved donor cornea after FBDLK was 2.9 (+ 1.5) days. The central corneal thickness decreased to normal level at 3 months after FBDLK, and stabilized at 515.6 (+ 50.6) microns at 1 year after FBDLK. The corneal edema and turbidity subsided rapidly within 1 month after FBDLK. At 3-6 months after surgery, the Haze level in the anterior matrix was significantly higher than that in the middle and posterior matrix (P = 0.000, Mann-Witney U test). The severity of Haze in the anterior matrix was different in different eyes. Two-dimensional logistic regression analysis showed that age was the main factor affecting the formation of Haze in the anterior matrix. Factor, 0.93; 95% confidence interval, 0.87-0.99, P = 0.015). Reflective structure of residual cells was observed in some frozen corneas (33.1%) under confocal microscope, and disappeared within one month after operation. After that, disordered acellular reflector and matrix cell aggregation appeared. There was a significant positive correlation (r = 0.46-0.51, P = 0.000-0.001) between the two groups at 3-24 months postoperatively. Haze formation under slit lamp microscopy corresponded to a large number of disordered acellular reflectors in the corneal stroma under confocal microscopy. The decrease of Haze corresponded to a decrease in disordered acellular reflectors and an increase in the number of stromal cells. Cell density increased gradually from 3 to 24 months after FBDLK. The density of stromal cells in anterior stroma was significantly higher than that in middle and posterior stroma (P 0.001, One-Way ANOVA). The density of stromal cells reconstructed in anterior, middle and posterior stroma reached 28%, 19% and 9% of normal cornea 2 years after FBDLK. The density of stromal cells was higher before 1 year after operation. The turbidity of graft-bed interface was more obvious at 1 month after operation, began to decrease at 3 months after operation, and basically decreased at 1 year after operation. There was a significant positive correlation between the turbidity of graft-bed interface and the disordered acellular reflector at 0.5-12 months after operation (r = 0.23-0.44, P = 0.000-0.02).
Conclusion: The edema and turbidity of frozen preserved donor cornea subsided at 1 month after FBDLK and recovered to normal corneal thickness at 3 months after FBDLK. Corneal stromal Haze may be an important phenomenon in the process of stromal cell remodeling after FBDLK, which is related to the disordered accumulation of acellular reflective substances. It was the most severe at 3 months after FBDLK and subsided at 1 year after FBDLK. Stromal cells were significantly higher than those in the middle and posterior stroma, and the density of stromal cells was still significantly lower than that of normal cornea at 2 years after surgery.
