Choroidal detachment along with retinal detachment as a presenting finding is rare. We identified five such cases presenting to our ophthalmology practice between 1964 and 1991. The patient is usually myopic and presents with marked visual loss, profound hypotony and a marked anterior chamber reaction. The pathogenesis seems to revolve around the hypotony and myopia and an unstable choroidal vascular system. Management usually involves a scleral buckling procedure with cryotherapy under direct visualization to release choroidal and subretinal fluid, possibly preceded by a few days of anti-inflammatory therapy. The overall prognosis is poor owing to delays in diagnosis and the postoperative development of proliferative vitreoretinopathy.
脉络膜脱离合并视网膜脱离作为首发表现较为罕见。我们在1964年至1991年间于眼科门诊发现了5例此类病例。患者通常为近视,表现为明显视力丧失、严重低眼压和显著的前房反应。发病机制似乎与低眼压、近视以及不稳定的脉络膜血管系统有关。治疗通常包括在直视下进行巩膜扣带术及冷冻疗法以排出脉络膜和视网膜下液,可能在术前先进行几天的抗炎治疗。由于诊断延误及术后增生性玻璃体视网膜病变的发生,总体预后较差。
