Curative application analysis of single-pass four-throw pupilloplasty in combined surgery of cataract and glaucoma / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To observe the application effect of single-pass four-throw pupilloplasty in combined surgery of cataract and glaucoma.<p>METHODS: Twenty eight patients(30 eyes)suffered from acute attack of glaucoma with large pupil and cataract, received cataract phacoemulsification and intraocular lens implantation combined with angle separation or trabeculectomy and single-pass four-throw pupilloplasty in apllication. Preoperative and postoperative visual acuity, pupil diameter and complications were observed, and postoperative visual quality were measured.<p>RESULTS: The visual acuity of 7d after operation was significantly improved without double vision and glare. The preoperative pupil diameter was 5.9+0.25mm, and the postoperative was 4.1±0.13mm(<i>P</i><0.05). Postoperative visual quality was significantly improved(<i>P</i><0.05). Among the intraoperative complications, there were 5 cases 5 eyes of iridodelamination avulsion after suture, 1 case 1 eye of small holes near the formed pupil and 3 cases 3 eyes of small blood seepage at the iris root, which recovered well after the corresponding treatment. The inflammation of anterior chamber were common at the early postoperative period, and inflammatory absorption after anti-inflammatory treatment. Long-term observation showed no loosening or shedding of the line knot in the pupil area.<p>CONCLUSION: Single-pass four-throw pupilloplasty is simple, safe and effective. It can obviously eliminate the visual impairment caused by the large pupil after acute glaucoma attack.

Evaluation methods of anterior chamber and angle structures after laser peripheral iridotomy / 中华实验眼科杂志

Laser peripheral iridotomy ( LPI) is one of the main therapy for glaucoma due to its reliable efficacy of widening peripheral angle and therefore decreasing intraocular pressure by partially relieving pupillary block. The parameters of the anterior chamber angle following the LPI are the main evaluation indexes. At present,the detecting and diagnosis technique for the anterior chamber angle is deeply advancing, including gonioscopy, ultrasound biomicroscopy, anterior segment optical coherence tomography and Pentacam. These methods offer some useful parameters and also present with some limits in the application respectively in the evaluation of anterior chamber and angle structure. This review focuses on the application of Methods mentioned above and morphologic changes of anterior chamber and angle structure following the LPI.
