Use of Fourier-Domain Optical Coherence Tomography to Evaluate Anterior Stromal Opacities in Donor Corneas

Table 1

Comparison of slit lamp and OCT findings in evaluating donor tissue for transplant suitability and depth of opacity as measured with FD-OCT.

Tissue number	CCT (μm)	Slit lamp finding	FD-OCT finding	Opacity depth (μm)	OCT impact tissue suitability?	Tissue use
1	669	Anterior Stromal Opacity	Epithelial	82	Yes	Endothelial keratoplasty
2	623	Epithelial	Anterior Stromal Opacity	278	Yes	Intended for transplant but microkeratome cut failed—tissue disposed of
3	705	Radial Keratotomy	Radial Keratotomy	624	No	Declined due to medical history
4	641	Midstromal Opacity	Midstromal Opacity	397	No	Endothelial keratoplasty
5	623	Anterior Stromal Opacity	Anterior Stromal Opacity	224	No	Endothelial keratoplasty
6	577	Anterior Stromal Opacity	Anterior Stromal Opacity	212	No	Poor endothelium—tissue disposed of
7	595	Anterior Stromal Opacity	Anterior Stromal Opacity	221	No	Tectonic grafting

CCT: central corneal thickness; FD-OCT: Fourier-domain optical coherence tomography.
