ABSTRACT

AIM:

To analyze and study the corneal nerve invasion phenomenon of Bowman's membrane in patients with IIIA lattice corneal dystrophy by confocal laser scanning microscopy. Quantitative analysis of 10a continuous observation image data was performed, followed by self-control studies.<p>

METHODS:

A total of 10 patients(13 eyes)with IIIA Lattice corneal dystrophy were continuously examined by confocal laser scanning microscopy. The data were observed and analyzed. <p>

RESULTS:

The normal corneal nerve of Bowman's membrane(Grade 0)of IIIA LCD patients gradually decreased with the prolongation of observation time. The nerves of grade I to V involved(amyloid-wrapped nerve fibers)gradually increased correspondingly. So suggested that the corneal nerve invasion of Bowman's membrane(amyloid deposits)in patients with IIIA LCD were gradually increasing with time. <p>

CONCLUSION:

In patients with type ⅢA lattice corneal dystrophy, there is a neurotropic phenomenon in Bowman's membrane, which gradually worsens with the aggravation of the lesion. This lesion can explain the recurrent epithelial damage of the IIIA LCD from some degrees. Continuous observation of patients with type IIIA LCD by corneal laser confocal microscopy can well understand the development of the lesion and explain its clinical manifestations.
