“…In this paper, we observed that 17 (77.3%) out of 22 patients with PIC were female, and 5 (22.7%) were male, which is in agreement with previous studies that showed that PIC is more prevalent in women than in men (10)(11) . The patients with n= number of eyes; SD= standard deviation; ACD= central anterior chamber depth; AOD500= angle opening distance at 500 µm from the scleral spur; ID1= peripheral iris thickness at 500 µm from the scleral spur; TPCD= trabecularciliary process distance; ICPD= iris-ciliary process distance; ARA= angle recess area In this paper, PIC was found in 10.2% of the patients with OAG and narrow-angle and in 6.3% of the patients with APAC.…”

“…ALPI is another laser treatment of choice if the anterior chamber remains appositionally closed after iridectomy. 7 When PAS have developed, intraocular surgery may be required. Surgery is considered as a last resort because it is often followed by a considerable number of complications.…”

Aims In this retrospective study, we aimed to evaluate the results of glaucoma surgery in patients with nanophthalmos. Methods Twenty-eight bilateral nanophthalmic patients, of whom 20 patients underwent trabeculectomy þ Mitomycin-C (MMC) þ inferior sclerotomy between 1996 and 2004, were included in this study. Records of patients with nanophthalmos were reviewed. Intraocular pressure (IOP), glaucoma medications, surgical success, visual acuity and complications were analyzed. Results The mean IOP was 34.675.3 mm Hg preoperatively. At the final follow-up visit, the mean IOP dropped to 21.4177.34 mm Hg (Po0.05). The cumulative probability of success was 85% at 1 year, 78.5% at 2 years, 76.9% at 3 years, 70.6% at 4 years and 47% at 5 years after surgery. Visual acuity decreased in 13 (65%) patients but no eye lost vision. Sequels of choroidal detachment (five patients 25%) and retinal folds (four patients 20%) were the most frequent reason for visual decrease. Uveal effusion (10 patients 50%) and cataract formation (seven patients 35%) were major late postoperative complications. Conclusions Results indicate that trabeculectomy þ MMC þ inferior sclerotomy procedure was effective and safe for glaucoma control in patients with nanophthalmos, but uveal effusion is a major problem and cataract surgery is expected in the long run.

“…As a result, the cysts in iridociliary sulcus or pars plicata are prone to push the weak root of the iris and ciliary zones. In some cases, the cysts can cause anterior rotation of the ciliary body and pseudoplateau configuration (Azuara-Blanco et al, 1996;Badlani et al, 2003;Ritch et al, 2003;Crowston et al, 2005;Shukla et al, 2008) by 'self space occupying' or 'posteriorpush' mechanism. Accordingly, the corresponding peripheral anterior chamber angle is narrowed or closed.…”

“…The cysts at the iridociliary junction or pars plicata identified by UBM can lead to anterior displacement of the iris root or anterior rotation of the ciliary body, accordingly cause narrow angle and even angle-closure glaucoma (Kuchenbecker et al, 2000;Badlani et al, 2003;Ritch et al, 2003;Crowston et al, 2005;Xiao et al, 2006;Dada et al, 2011). However, to our best knowledge, there have been no reports addressing the clinical relevance between cysts and shallow anterior chamber.…”

Abstract:Objective: To evaluate the prevalence of primary iris and/or ciliary body cysts in eyes with shallow anterior chamber and their effect on the narrowing of the anterior chamber angle. Methods: Among the general physical check-up population, subjects with shallow anterior chambers, as judged by van Herick technique, were recruited for further investigation. Ultrasound biomicroscope (UBM) was used to detect and measure the cysts located in the iris and/or ciliary body, the anterior chamber depth (ACD), the angle opening distance at 500 µm (AOD500), and the trabecular-iris angle (TIA). A-scan ultrasonography was used to measure the ocular biometry, including lens thickness, axial length, lens/axial length factor (LAF), and relative lens position (RLP). The effect of the cyst on narrowing the corresponding anterior chamber angle and the entire angle was evaluated by the UBM images, ocular biometry, and gonioscopic grading. The eye with unilateral cyst was compared with the eye without the cyst for further analysis. Results: Among the 727 subjects with shallow anterior chamber, primary iris and ciliary body cysts were detected in 250 (34.4%) patients; among them 96 (38.4%) patients showed unilateral single cyst, 21 (8.4%) patients had unilateral double cysts, and 42 (16.8%) patients manifested unilateral multiple and multi-quadrants cysts. Plateau iris configuration was found in 140 of 361 (38.8%) eyes with cysts. The mean size of total cysts was (0.6547±0.2319) mm. In evaluation of the effect of the cyst size and location on narrowing the corresponding angle to their position, the proportion of the cysts causing corresponding angle narrowing or closure among the cysts larger than 0.8 mm (113/121, 93.4%) was found to be significantly higher than that of the cysts smaller than 0.8 mm (373/801, 46.6%), and a significant higher proportion was also found in the cysts located at iridociliary sulcus (354/437, 81.0%) than in that at the pars plicata (131/484, 27.1%). In evaluating the effect of the cyst on the entire anterior chamber angle, the eyes with multiple and multi-quadrants cysts manifested significant narrowing of the entire anterior chamber angle as compared with the eyes without cysts, based on the data analysis in comparison of TIA, AOD500, and gonioscopic grading evaluation. The unilateral single or double cysts in the eyes had no significant effect on narrowing of anterior chamber angle as compared with eyes without cysts. The iris and/or ciliary body cysts did not seem to affect the axial length, ACD, lens thickness, RLP, LAF. Conclusions: The prevalence of primary iris and ciliary body cyst was 34.4% in the subjects with shallow anterior chamber. The cysts larger than 0.8 mm, locating at iridociliary sulcus, or multiple and extensive cysts were inclined to cause the angle narrowing or closure.
