“…This incidence may be related to the fact that patients with PACD are more likely to come to the hospital for examination due to eye discomfort and thus have a higher probability of cysts screened by UBM. Our data showed that patients with cysts were mainly 40-79 years old, which was also the peak onset age of PACD (11).…”

Aim: To investigate the incidence and clinical features of primary iris and ciliary body cysts in Chinese primary angle closure disease (PACD). Patients were evaluated by measuring and analyzing the cysts with an ultrasound biomicroscope (UBM).Methods: The data of patients diagnosed with PACD were reviewed. Demographic data were collected, and the cyst number, size, location, and trabecular-iris angle (TIA) were measured, with the size including the longest diameter (LD) and its corresponding vertical diameter (CVD).Results: A total of 1,334 cases (2,317 eyes) were reviewed, and 409 cysts were found in 131 cases (168 eyes), with an average of 2.43 ± 3.14 cysts per eye. The ages of the patients with cysts ranged from 25 to 80 years, with an average age of 55.24 ± 12.22 years. The detection rate was 7.3%, and the majority of cysts were located in the iridociliary sulcus. Among the 131 patients, 94 had monocular cysts, while binocular cysts occurred in 37 patients. The locations of the cysts in both eyes were mainly in the inferior and temporal quadrants (42.5 and 34.0%, respectively). The cysts were mainly of medium size (49.9%), followed by small cysts (33.3%), large cysts (14.7%) and giant cysts (2.2%). The average LD was 0.68 ± 0.33 mm, and the average CVD was 0.45 ± 0.23 mm. There were no statistically significant differences in the TIA between the cyst area and unaffected area.Conclusions: The incidence of cysts is 7.3% in the PACD population. The cysts are mainly monocular, medium in size, and located in the iridociliary sulcus. Additionally, the cysts were located mainly in the inferior and temporal quadrants. These cysts have little effect on the anterior chamber angle.

“…With regard to the incidence of cysts, the data obtained by different researchers varied greatly (6,9,11). After carefully analyzing the respective research methods and survey populations, we speculated that the differences in incidence may be due to race, age and disease characteristics of the subjects.…”

“…In our study, some patients underwent ICL implantation surgery with preoperative iris ciliary cysts. The incidence of iridociliary cysts ranged from 4.9% (1157 patients) to 54.3% (116 patients), which showed no consensus and the large iridociliary cysts caused anterior chamber angle closure and increased the risk of secondary glaucoma [ 10 , 16 , 17 ]. Most of the diameter of the cysts are less than 1 mm and have no effect on phakic IOL implantation.…”

BackgroundTo analyze the positions of intraocular posterior Implantable Collamer Lens (ICL) and its possible relationship with vault.MethodsThis cross-sectional study included 72 patients with high myopia (134 eyes) who were followed up after phakic intraocular lens implantation. The postoperative time ranged from 1 week to 7 years. We obtained the images of ICL by using Compact Touch STS UBM and observed the position of ICL in posterior chamber and ciliary sulcus. The horizontal lines vault was measured and recorded.ResultsThere were various positions in the posterior chamber as observed by full-scale ultrasound biomicroscopy and the haptics were inserted at different positions. -Eight seven eyes (64.9%) that obtained ideal vault, 29 eyes (21.6%) had insufficient vaults and 18 eyes (13.4%) had excessive vault. The vault with various positions of haptics was in ideal range (250 μm–750 μm) almost in each group. Three eyes in this study with haptics on the top of ciliary sulcus obtained excessive vault (mean vault, 850.00 ± 70.71 μm) and one eye appeared one side haptics pushing forward the iris. Among five eyes (3.7%) with iridociliary body cysts, three eyes (60%) obtained ideal vault. One eye (0.7%) with ICL decentralization after implantation surgery had an ideal vault, but the patient had serious glare.ConclusionsThough ICL in the posterior chamber had different positions and the haptics in most cases were not in the ciliary sulcus, the postoperative vault was almost in the ideal range.

“…Moreover, UBM has shown that iridociliary cysts can sometimes lead to angle closure [26] by mechanical anterior displacement of the iris, or even to angle-closure glaucoma [1,3,4,28,29]. Primary iridociliary cysts are usually discovered in young persons [9,25], they tend to be solitary and unilateral [7,13,25], they only rarely occupy multiple quadrants, with the inferior and temporal quadrants being more commonly affected [6,9,25], and only rarely do they enlarge to a size that can compromise the angle [25]. In contrast to the above-described typical presentation of primary iridociliary cysts, we hereby describe an unusual case of primary iridociliary cysts that were multiple, bilateral, discovered in advanced age, occupying all quadrants, and being associated with chronic angle-closure glaucoma.…”
