In the case of central corneal haze, which method is typically used for assessment?

The assessment of central corneal haze is most effectively done using a slit lamp with sclerotic scatter illumination. This method allows for a detailed and illuminated view of the cornea, facilitating the detection of any opacities present in the corneal tissue. The slit lamp's capabilities provide a three-dimensional view of the cornea, enabling an ophthalmic professional to evaluate the depth, extent, and severity of haze. Sclerotic scatter illumination enhances the visibility of corneal irregularities by using a narrow beam of light, which highlights the changes in the cornea due to haze more effectively than other methods.

Other methods, such as observation in a dark room, would not provide the clarity or detail needed to assess corneal haze specifically. A digital eye chart would primarily measure visual acuity rather than the structural condition of the cornea. Fundus examination focuses on the retina and optic nerve, which is unrelated to the condition of the cornea. Thus, using a slit lamp with sclerotic scatter is the most appropriate and accurate method for assessing central corneal haze.
