Development of posterior staphyloma in a child with retinitis pigmentosa and high myopia detected by Ultra-widefield Optical Coherence Tomography: A 4-year follow-up.

PURPOSE: To describe the formation of posterior staphyloma in a retinitis pigmentosa (RP) patient.

OBSERVATIONS: A 5-year-old girl with RP and high myopia developed posterior staphyloma after 2 years. In the 2 years following this, the edges of the staphyloma deepened, and the staphyloma extended toward the posterior pole. The posterior staphyloma presented as a narrow macular type. During follow-up, staphyloma deepening was accompanied by axial elongation and increased myopic refractive error.

CONCLUSIONS AND

IMPORTANCE

This case highlights the onset and progression of posterior staphyloma in patients with RP, demonstrating that staphyloma related to RP occurs even in childhood.
