Posterior lenticonus is a protrusion of the posterior capsule and cortex into the vitreous. The etiology is widely debated because of the rare nature of the condition. Lenticonus can present with concurrent ocular conditions, which can disrupt normal visual development. Currently, the only treatment option for posterior lenticonus is lensectomy, which may still have a reduced chance of visual success secondary to the associated disease. Although strabismus and amblyopia are commonly associated, keratoconus has not previously been reported with unilateral posterior lenticonus. Considering treatment of the associated condition may allow the patient to delay or forego surgical intervention.
后圆锥晶状体是后囊膜和皮质向玻璃体的突出。由于这种情况罕见，其病因存在广泛争议。圆锥晶状体可能伴有并发眼部疾病，这会干扰正常的视觉发育。目前，后圆锥晶状体唯一的治疗选择是晶状体切除术，由于相关疾病，其视觉成功的几率可能仍然较低。虽然斜视和弱视通常相关，但此前尚未有圆锥角膜与单侧后圆锥晶状体相关的报道。考虑对相关疾病进行治疗可能会使患者推迟或放弃手术干预。
