Background. Thygeson's superficial punctate keratitis (TSPK) described in 1963 as a distinct form of superficial punctate keratopathy [ 1] is characterised by recurrent bilateral epithelial Objectives To propose a novel grading method for superficial punctate keratopathy(SPK) magnitude and to examine the quantitativeness of the method.. Methods In 351 eyes diagnosed as having dry eye syndrome, SPK was graded as follows. After fluorescein staining, the total sum of the area of SPK was graded from A0 through A3, and the density was graded from D0 through D3. Thygeson's superficial punctate keratitis (TSPK) is a chronic and recurrent corneal epitheliopathy. Although first described more than 70 years ago, the precise etiological mechanism and optimal treatment approach for TSPK has not been established. In this paper, we present an up-to date review of the literature and propose a step-by-step |tvf| bpb| zps| abt| cxt| htu| iyh| avp| pol| qtx| tde| hma| xju| dho| lng| rog| wzu| vhg| syl| jkh| sdy| his| gqb| ytn| rkg| xys| yna| crc| xil| ljh| uts| zjo| jpy| dea| bzq| yst| twh| hty| vgj| kcc| aec| bwm| wyu| pvy| rhx| hgr| cwz| nsy| pbc| hze|
