Any eye protrusion of more than 17.8 mm for Iranian children, 19 mm for Iranian teenagers, and 19.3 mm for Iranian adults and relative eye protrusion of more than 2 mm warrants further clinical examination. Age and base value had a significant impact on normal eye protrusion values.

IVB injection before vitrectomy for PDR facilitates the surgery, and may decrease the rate of postoperative vitreous hemorrhage and improve the visual acuity results of the operation.

A low risk of endophthalmitis consistent with the range of previous studies was observed notwithstanding the usage of multiple use of a single vial. Postinjection antibiotic drops may not be necessary.
