摘要
我們檢查49位63眼，包括原發性開放性2位3眼，慢性或亞急性原發性閉鎖性青光眼24位32眼，及續發於白內障術後青光眼23位28眼。術後追踪均半年以上結果顯示原發性青光眼在白內障術後，眼壓控制好轉者占34%，原有瀘孔在白內障角膜切入術後仍能維持有效者占42%，而與手術是否顯利無關。至於手術後視力不佳最主要的原因為視神經和角膜的損害。 在續發性青光眼中，以周邊前點連占有極重要的地位，而且和眼壓控制的難易有相當的配合。由於白內障術後可有1~7%發生青光眼的可能，應有術後隅角鏡的檢查而小心追踪。 此外，白內障術後的低壓時間，究竟可有多長？在我們對原發性及續發性無晶體性青光眼的研究顯示有1/8以上的患者，在術後半年以上才發生眼壓的升高，因此長期眼壓的追踪實有其必要，尤其在隅角顯示有厲害前黏連者。

Sixty-three aphakic eyes with glaucoma, including 3 eyes with primary open angle glaucoma (POAG), 32 eyes with chronic or subacute angle-closure glaucoma and 28 eyes with secondary glaucoma due to cataract extraction, were studied retrospectively. After cataract extraction, 34% in POAG got better pressure control, 42% of filtering blebs continued functioning by corneal incision. Of all the secondary glaucoma peripheral anterior synechia (PAS) was the most frequent (82%) mechanism. The extent of PAS involvement paralled with the severity of glaucoma. One interesing aspect was the prolonged period of post-operative hypotension effect. In our study, thereare one-third patients who developed glaucoma after more than half a year. The regular post-operative gonioscopy and intraocular pressure follow-up are imperative.
