The incidence of iatrogenic peripheral retinal breaks during vitrectomy for macular diseases is significantly lower in 23-gauge vitrectomy than in 20-gauge vitrectomy.

A full-thickness macular hole may develop in pediatric patients. Although the etiology of the macular hole in the present patient is unclear, tangential traction induced by contraction of the peripapillary membrane, presumed to be an incomplete regression of the Bergmeister papilla, might have been responsible for the formation of the macular hole.

These findings suggest that an elevation of the cone outer segment tips line in the normal fellow eyes of patients with macular holes is caused by the focal traction of the vitreous at the foveal center. This is considered to be an important primary change observed in the macular tissue in full-thickness macular hole formation.
