Dear Editor,

I congratulate the authors Sulochana et al for their original article titled "Trace elements iron, copper and zinc in vitreous of patients with various vitreoretinal diseases".

Their conclusion was that patients with proliferative diabetic retinopathy (PDR) and Eales disease had higher concentrations of iron in the vitreous compared to the other sub groups of patients. They have explained that the intraocular foreign body (IOFB) group also had higher iron concentration in vitreous, which they attributed to the foreign body itself. The indication for vitrectomy in patients with PDR and Eales disease is non-resolving vitreous haemorrhage. The higher iron concentration in the vitreous of these patients could be due to the vitreous haemorrhage. However, the authors have not mentioned this. In the materials and methods section they have said that vitreous samples contaminated with blood were not analysed. However, a long-standing vitreous haemorrhage may not be red in colour to brand it as contaminated with blood. The study group is a heterogenous group and does not allow any comparison.
