前房消失的临床类型: 1.前房消失伴低眼压:由于房水外渗所致,多见于白内障或抗青光眼手术后,后者更多见。此外,挫伤后,小裂口未被发现,房水不断外渗,阻止疤痕形成。低眼压常伴有脉络膜脱离。药物(Diamox)治疗在于减少睫状体分泌房水,从而减缓瘘口之房水外渗,有利于疤痕形成。大部分病例经此处理,伤口愈合,眼压上升,脉络膜脱离消失。若数天后(为避免房角粘连,白内障术后至多5天),仍无好转,应手术治疗:发现有瘘口,缝合关闭之;有脉络膜脱离,宜采用本方法解决。 2.前房消失伴高眼压:一般见于白内障手术后瞳孔阻滞和抗青光眼术后出现恶性青光眼者。
Clinical manifestations of disappearance of anterior chamber: 1. Anterior chamber disappeared with low intraocular pressure: due to aqueous extravasation, more common in cataract or anti-glaucoma surgery, the latter more common. In addition, the contusion, the small gap was not found, aqueous extravasation continued to prevent the formation of scars. Low intraocular pressure often associated with choroidal detachment. Drug (Diamox) treatment is to reduce the ciliary body to secrete aqueous humor, thereby slowing the extravasation of aqueous humor, is conducive to the formation of scars. Most cases after this treatment, wound healing, intraocular pressure increased, choroidal detachment disappeared. If a few days (in order to avoid corner adhesion, cataract surgery up to 5 days), still no improvement, surgery should be: found fistula, suture closure; choroidal detachment, should be used to solve this method. 2. Anterior chamber disappeared with high intraocular pressure: generally seen in cataract surgery pupil block and anti-glaucoma surgery after malignant glaucoma.
