Relation of posterior staphyloma in highly myopic eyes with macular hole and retinal detachment

Purpose: To investigate whether the type of posterior staphyloma (PS) affects the development of macular hole and retinal detachment (MHRD) in high myopia. Methods: Included in this retrospective study were 28 highly myopic eyes with MHRD (MHRD group) and 47 highly myopic eyes without MHRD (control group). The presence or absence of PS and the type of PS according to the classification of Curtin, the postoperative visual acuity, and the retinal reattachment rate were investigated. Results: The percentage of eyes with PS was significantly higher in the MHRD group than in the control group (P < 0.001). The rate of type II PS was significantly higher in the MHRD group (P = 0.01). There were no significant differences among the types of PS regarding the retinal reattachment rates and visual outcome. Conclusions: Eyes with type II PS have a higher risk for the development of MHRD. However, the type of PS did not seem to affect the anatomic and visual outcome.
