My brother had a redness in left eyes from the last 1 week with watery and irritation feeling. Upon consulting the eye specialist first he provided a eye drop as for eye infection first. Still after 1 week the issue persisted, then we have visited again and checked with him again. He has done an examination and found reason for this eye redness is due to be named as " Microsperidiosis" . He as given now additional eye drop named Sodium Hyaluronate with the last given medicine named "Primox Eye Drop". Whether the condition of my brother is serious or it will take time resolved. Please help.
