We evaluated changes in aqueous outflow and blood-aqueous barrier (BAB) disruption after cataract surgery in two randomly selected groups of eyes. In one group, a high-viscosity viscoelastic was used for intraocular lens (IOL) implantation; in the other, a low-viscosity viscoelastic. Fluorophotometry was used to evaluate aqueous humor dynamics five to seven hours after IOL implantation. Aqueous outflow after IOL implantation in operated eyes was nearly twice that in the fellow eyes, which served as controls. Mean protein concentration in the anterior chamber was also elevated in operated eyes. However, postoperative aqueous outflow did not differ significantly between the two groups. The substantial increase in aqueous outflow observed postoperatively and the increase in aqueous humor protein concentration were closely related to BAB disruption. These results suggest that BAB disruption may be a main cause of the transient high intraocular pressure observed after IOL implantation in both groups.

We retrospectively reviewed the records of patients followed for over 4 years after undergoing trabeculotomy to treat primary open-angle glaucoma (POAG) to evaluate the long-term effects of the procedure on intraocular pressure (IOP) control. IOP remained below 15 mm Hg, with no need for postoperative medication in 7 (13.2%) of 53 eyes. IOP was below 15 mm Hg in an additional eight eyes (15.1%) treated with topical medication. Topical medication was needed to maintain IOP between 16 to 20 mm Hg in 23 eyes (43.4%). Oral acetazolamide or additional surgery was needed in 15 (28.3%). A postoperative IOP below 20 mm Hg with or without topical medication was associated with a survival probability of 71.2%, Our results demonstrated that, although trabeculotomy largely failed to maintain an "ideal" postoperative IOP (below 15 mm Hg), it was not associated with severe operative or postoperative complications such as flat anterior chamber. Thus, the procedure probably should be the first choice not only in uncomplicated cases of congenital glaucoma and pseudoexfoliation glaucoma (as previously established), but also in cases of POAG in young patients with only slight damage to the optic disc or visual field and cases with forward movement of the iris-lens diaphragm.

We surveyed data collected in our department over the past 5 years on all patients under the age of 30 years who had presented for repair of retinal detachment. Of 52 such patients, 10 (19.2%) had a documented history of atopic dermatitis. Three (27.3%) of the 11 eyes (10 patients) with atopic dermatitis exhibited a break in the ciliary epithelium in the pars plicata and pars plana, the most characteristic finding in this group. Surgical reattachment of the retina was accomplished in all 11 eyes. To repair a tear in the ciliary epithelium in atopic cases, we prefer using an encircling procedure to reconstruct an artificial ora serrata.

The anterior segment of the eye is displayed on the video monitor using a slitlamp apparatus (slitlamp 75SL, Zeiss, Germany) combined with a video camera and the video image is then analyzed with a computer to convert the optimal image into the true image. The profile of the true image of the anterior eye segment allows us to estimate the pupil-blocking force, which is the posteriorly directed vector exerted in the iris tissue, according to Mapstone’s theory. In mensuration by digitizer on 3 occasions from a single video image of a given normal eye, the Pbf was ––0.025 5 ± 0.0011 Λ (= Young’s module). And the pupil-blocking force of 10 procedures in a given glaucomatous eye was +1.092 ± 0.018 Λ.
