Equine corneal and conjunctival cytology: Practical tips

Cytology is a simple economical procedure which may provide rapid diagnostic information for horses suffering from ocular surface disease. Collection of diagnostically useful specimens is the key initial step in cytology. The technique used will vary depending on the nature of the ocular surface disease and consideration of the pros and cons of different sampling methods. This manuscript provides with some tips on how to perform corneal and conjunctival cytology and when it can be useful.

Different instruments which may be used to perform the sampling are also described.

The authors have added a clinical case to emphasize how important cytology can be in both the diagnosis and treatment of surface ocular disease.
