This requires a fluorescence microscope and microbiologist to study images. Trypan blue is an simply available stain that may be utilised by ophthalmologists and straight studied without the need of any unique microscope. This approach features a sensitivity of more than 75 and specificity of 68 [39, 40]. IKI-H2SO4 stain is a recent addition that especially stains Pythium, but not fungal filaments, and different studies show a specificity close to 100 [9, 41]. The sensitivity and specificity of a variety of stains is with respect to culture final results of PI keratitis. One particular or different combinations of the above, along with a educated eye and clinical suspicion, can assist inside the early detection of PI keratitis. In vivo confocal microscopy (IVCM) has been shown to demonstrate hyperreflective beaded string-like branching structures, but they can not differentiate Pythium from fungus or Nocardia [36, 42].
