Abstract
Purpose: :
Many patients with Retinopathy of Prematurity (ROP) vascularize to the far retinal periphery, but not all.(1,2,3) Similarly some hereditary retinal conditions such as Familial Exudative Retinopathy and Incontinentia Pigmenti (IP) behave in a similar fashion. The purpose is to present long term followup of over 30 years in two cases of ROP and one of asymptomatic IP in one eye followed for 13 years.
Methods: :
Patients with long term followup were selected to illustrate nonvascularization of the far peripheral retina in ROP and IP.
Results: :
One ROP case followed for 51 years never vascularized beyond the ridge while a second followed for 35 years did. A 13-year-old girl with IP first seen at 4 months of age developed PVR in her right eye. She did not vascularize beyond the equator in her left eye and suffered no retina problems as she got older.
Conclusions: :
Some pediatric vitreoretinal disorders where vascularization does not reach the far retinal periphery suffer no retinal ill effects in later life.
