Multiple iridociliary cysts: One entity with various clinical presentations. Am J Ophthalmol Case Rep 2022; 28:101694. [PMID: 36111280 PMCID: PMC9467891 DOI: 10.1016/j.ajoc.2022.101694] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Revised: 08/23/2022] [Accepted: 08/28/2022] [Indexed: 11/22/2022] Open
Abstract
Purpose Iris cysts have a wide range of clinical manifestations ranging from totally asymptomatic to full-blown glaucoma. The aim of this report is to present three patients with multiple bilateral iridociliary cysts. Each one of them had a different stage of glaucoma and required individualized management. Observations All three patients presented to our clinic. Patient 1 was a 25-year old female with no symptoms and normal intraocular pressure (IOP), Patient 2 a 20-year old female with cup-disk asymmetry and nocturnal IOP spikes and Patient 3 a 69-year old male with chronic angle closure, uncontrolled IOP on maximum medical therapy and optic nerve cupping. During clinical evaluation, gonioscopic findings raised the suspicion of possible multiple bilateral iridocilary cysts, which were then verified with ultrasound biomicroscopy in all patients. Each case was managed differently; Patient 1 was opted for observation, Patient 2 was started on prostaglandin analogue and Patient 3 underwent trabeculectomy with Mitomycin-C. Conclusions and Importance Although iris cysts represent a relatively rare entity, patients with this anomaly can be encountered in our everyday clinical practice. They may be totally asymptomatic, where observation alone suffices, or at the other end of the spectrum, they may present with full-blown glaucoma, requiring traditional glaucoma surgeries. Considering the wide variety of clinical manifestations and that management may differ depending on the diagnosis, it is highly important for clinicians to carry out a careful examination, especially in patients with narrow angle. In cases of high suspicion for iris cysts, ancillary testing, such as Ultrasound Biomicroscopy, should be performed for the definite diagnosis as well as for the exclusion of malignancies.

A case of bilateral diffuse uveal melanocytic proliferation with secondary angle closure caused by ciliary body thickening. Am J Ophthalmol Case Rep 2022; 28:101729. [PMID: 36324629 PMCID: PMC9619173 DOI: 10.1016/j.ajoc.2022.101729] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 08/28/2022] [Accepted: 10/17/2022] [Indexed: 11/06/2022] Open
Abstract
Purpose To describe a case of bilateral diffuse uveal melanocytic proliferation (BDUMP) with secondary angle closure caused by ciliary body thickening accompanied by intraocular pressure (IOP) elevation after mydriasis. Observations A 55-year-old woman with a history of ovarian cancer had blurred vision in both eyes. Fundus examination revealed multiple patchy lesions in both eyes and a nevus-like elevated lesion in the right eye. Anterior segment optical coherence tomography (AS-OCT) and ultrasound biomicroscopy (UBM) demonstrated angle closure resulting from ciliary body thickening. After mydriasis, the IOP was elevated in both eyes. Instillation of a miotic drug successfully reversed the IOP to normal levels. Conclusions and Importance BDUMP caused secondary angle closure in both eyes, presumably due to thickening of the entire ciliary body. AS-OCT and UBM were advantageous for analyzing the morphology of the anterior eye segment in BDUMP. Clinicians should be aware of the possibility of angle closure during the management of patients with BDUMP.

Abstract
PURPOSE To describe the long-term outcomes of eyes with bilateral and multiple ciliary body cysts (CBC). METHODS This retrospective study included patients with multiple and bilateral CBC diagnosed by high-resolution ultrasound biomicroscopy and followed by a single glaucoma specialist from 2000 to 2020. All patients underwent complete ophthalmic examination including dynamic indentation gonioscopy, retinal nerve fiber layer (RNFL) measurement by optic coherence tomography and automated perimetry. RESULTS Seven patients (14 eyes) with bilateral and multiple CBC were included with a mean follow-up of 98±39 months. Four eyes of 2 patients had complete angle closure at first examination and 3 of them underwent trabeculectomy with good visual outcomes. Four eyes of 2 patients had a reversible angle-closure at first examination and underwent a ultrasound biomicroscopy-guided laser peripheral iridotomy (LPI) which reopened the irido-corneal angles. Two of these eyes needed intensification of hypotensive drops during the follow-up. Among the 6 eyes (3 patients) with open angle at first examination, all had had LPI at last follow-up visit, 5 had normal RNFL and visual field and 1 received an additional hypotensive drop because of RNFL progression. CONCLUSION Our long-term cohort of bilateral and multiple CBC demonstrates that this rare entity may have a good prognosis if LPI is performed before extension of peripheral anterior synechiae. Irreversible angle closure required trabeculectomy in 75% of cases in our cohort with however good visual outcomes.

Abstract
PRECIS Argon laser peripheral iridoplasty (ALPI) was performed on 48 eyes with plateau iris syndrome (PIS). Indentation gonioscopy was used to monitor the opening of the iridocorneal angle. Mean intraocular pressure (IOP) at 5 years decreased from 15.9 to 14.4 mm Hg. None of the eyes required trabeculectomy. PURPOSE The purpose of this article was to report the long-term outcomes of ALPI for PIS. MATERIALS AND METHODS A retrospective chart review was performed on all patients with PIS treated with ALPI from 2001 to 2012. The study included 48 eyes from 28 patients with PIS after peripheral iridotomy, with a follow-up of at least 5 years. Patients with advanced glaucoma requiring initial surgical treatment (pathologic discs and IOP above the target IOP despite medical treatment) were excluded. The primary outcomes were the effect on the number of IOP medications, and the need for complementary selective laser trabeculoplasty (SLT) or surgery (trabeculectomy and/or phacoemulsification). Secondary outcomes were optic nerve head changes and adverse events. RESULTS The mean IOP statistically decreased after ALPI (15.91±2.62 vs. 14.35±2.18 mm Hg, P>0.001). The mean number of IOP-lowering medications statistically increased after ALPI (0.81±0.94 vs. 1.2±1.04, P>0.001). Mean follow-up was 92.4±26.5 months. At the end of the follow-up, 12 (25%) eyes had no medications, 20 (42%) had 1 medication, 11 (23%) had 2 medications, 3 (6%) had 3 medications, and 2 (4%) had 4. Ten (21%) eyes underwent SLT, 6 (10%) underwent phacoemulsification, and no trabeculectomy was necessary during follow-up. The change in cup to disc ratio from pre-ALPI to latest follow-up was not statistically significant, and no adverse events were reported. CONCLUSIONS ALPI is relatively effective and safe to prevent angle-closure glaucoma and avoid trabeculectomy in patients with PIS. This procedure often helps to control IOP, although SLT and additional medical treatments are frequently necessary to maintain the target IOP.

Abstract
PURPOSE To report a case of patient with Miller Fisher syndrome, complicated by simultaneous bilateral acute angle-closure glaucoma in her slightly (+1.5) hyperopic eyes. METHODS We present a case report of a 71-year-old female patient presenting with total ophthalmoplegia, areflexia, ataxia and bilateral acute angle-closure glaucoma. RESULTS The initial ocular examination revealed hand motion in the both eyes and oedematic corneas. Initial intraocular pressure was immeasurable high (measurment by Tonopen Avia). Measurement was possible after intravenous Mannitol 20 % infusion on both eyes as 54 and 56 mm Hg, respectively. Local medical therapy of pilocarpine, timolol, dorsolamide and dexamethasone improve intraocular pressure into normal limits within several hours. Prophylactic peripheral Nd-YAG laser iridotomy was performed on a both eyes two days later. Systemic treatment involved plasma exchange and rehabilitation program. Subsequent cataract surgery on both eyes with posterior capsule lens implantation improve the best corrected visual acuity on right eye from 0.5 to 1.0 and the left eye from 0.5 to 0.8, respectively. Intraocular pressure is within normal limits without any glaucoma therapy. Follow up period is three years. CONCLUSIONS This is the second reported case of patient with Miller Fisher syndrome and simultaneous bilateral acute angle-closure glaucoma and the fifth reported case of Miller Fisher syndrome and acute angle-closure glaucoma. Treatment for both conditions made a very good recovery.

Abstract
A 39-year-old Caucasian man with bilateral narrow angles, a plateau-like iris configuration on gonioscopy and elevated intraocular pressure (IOP) presented with significant asymmetric glaucoma, left eye affected more than right. Initial management with topical medical therapy, laser iridoplasty and peripheral iridotomy in the left eye was ineffective in lowering the IOP or opening the anterior chamber angle. Ultrasound biomicroscopy demonstrated bilateral ciliary body cysts. The patient ultimately required surgical management, consisting of cataract extraction and endoscopic cyclophotocoagulation of ciliary body cysts in the left eye and trabeculectomy in the right eye, for persistent IOP control to prevent further optic nerve damage and subsequent visual field loss.

Abstract
AIM To investigate the efficacy and safety of krypton laser peripheral iridoplasty (LPIP) for Chinese patients with primary angle closure (PAC) or primary angle-closure glaucoma (PACG) status post laser iridotomy in reversing the positive results of the dark room provocative test (DRPT). METHODS This study was prospective, noncomparative, interventional case series. Thirty-three patients (thirty-eight eyes) with PAC or PACG status post patent laser iridotomy and maintained normal intraocular pressure (IOP) but with positive DRPT results were enrolled. All the subjects were treated with krypton LPIP. DRPT was repeated after krypton LPIP. Results of DRPT were recorded. The visual acuity, IOP and gonioscopy were analyzed before and after krypton LPIP. A minimum time limit for follow-up was 6mo. RESULTS Thirty-three patients (thirty-eight eyes) were followed for 17.7±8.37mo (range 7-41mo) after LPIP. Positive results of DRPT decreased from 38 eyes to 9 eyes (23.7%) after LPIP. Peripheral anterior synechiae of angle in 34 of 38 eyes (89.5%) remained unchanged at dynamic gonioscopy throughout the follow-up period after LPIP. CONCLUSION LPIP decreased positive rates of the DRPT significantly. The mechanism may be that LPIP minimized contact between the peripheral iris and trabecular meshwork, which is a key factor for developing peripheral anterior synechiae.

Abstract
PURPOSE To report a case of acute glaucoma due to complete ring cyst of the ciliary body. PATIENTS AND METHODS A 33-year-old woman experienced blurred vision in her left eye. Intraocular pressure of the left eye was elevated accompanied with a very shallow anterior chamber. Anterior segment-optical coherence tomography and ultrasound biomicroscopy detected ring-shaped ciliary masses in the both eyes. Myopic change and contact between the ciliary mass and lens in the left eye suggested the presence of aqueous misdirection resulting in forward displacement of the lens-iris diaphragm. Because elevated intraocular pressure was refractory to conservative management, the left eye underwent clear lens aspiration and implantation of intraocular lens. RESULTS Although the anterior chamber became deep in the left eye initially after lens extraction in conjunction with core vitrectomy, possible aqueous misdirection recurred. Second vitrectomy in the left eye together with posterior and anterior capsulotomies, to establish humoral communication between the anterior and posterior chambers, deepened the anterior chamber and lowered the intraocular pressure. The anterior chamber in the fellow right eye remained deep a year after the episode. CONCLUSIONS This is the first reported case of bilateral ring cysts of the ciliary body. The manifestation caused secondary glaucoma, which was resolved by lensectomy and vitrectomy.

Abstract
Secondary angle closure glaucomas are a distinct entity from primary angle closure glaucoma (PACG). Unlike PACG, secondary angle closure glaucoma's have an identifable contributory factor/s for angle closure and obstruction of aqueous fow which is usually unrelieved by iridotomy. The treatment of each type of secondary angle closure glaucoma is varied, so identification of the primary cause aids in its effective management. How to cite this article: Annadurai P, Vijaya L.

Abstract
AIM To investigate the relationship between the ultrasound biomicroscopic (UBM) features of anterior-segment cysts (ASCs) and increased intraocular pressure (IOP) as a risk factor for closed-angle glaucoma (CAG). METHODS Totally 24 eyes with recently diagnosed ASCs were divided into two groups. First group with ASC and ocular normotension (n=13), second group with ASC and ocular hypertension (n=11). An ophthalmologic examination, including tonometry, slit-lamp biomicroscopy (SLBM), gonioscopy, fundoscopy, pentacam, and UBM, was performed. The features of the ASCs were compared with the IOP. RESULTS ASCs were accurately diagnosed and delineated in 24 eyes using UBM. IOP was elevated in those ASCs with a secondary aetiology (P=0.027), iridociliary location (P=0.006), deformed shape (P=0.013), increased size (P=0.001) and elongated pupillary aperture (P=0.009). However, the count (P=0.343) of ASCs, anterior chamber depth (ACD; P=0.22) and axial lenght (AL; P=0.31) were not associated with ocular hypertension. Correlations were found between the IOP and ASC size (r=-0.712; P=0.003), anterior chamber angle (ACA; r=-0.985; P<0.001), angle opening area (AOA; r=0.885; P<0.001), angulation of iris (r=-0.776, P<0.001), and affected iris quadrant (r =-0.655, P=0.002). CONCLUSION Ocular hypertension in some eyes with ASC might be associated with various mechanisms, including secondary aetiology, iridociliary location, deformed shape, increased size and elongated pupill, which can be determined by UBM.

Abstract
Primary iridociliary cysts can induce plateau iris configuration and angle closure glaucoma. We report a patient with bilateral, primary, ring-shaped, solitary iridociliary cysts. The right eye displayed normal intraocular pressure, oppositional iridocorneal angle closure, and healthy optic nerve head. The left eye had advanced chronic angle closure glaucoma. The management strategy varied between eyes and is discussed. This, to the best of our knowledge, is the first report of transscleral Diode laser application in an eye with a large iridociliary cyst.

Abstract
PURPOSE To report a case of a peripheral pigment epithelium iris cyst treated with selective laser trabeculoplasty laser. CASE REPORT A 15-year-old girl applied to our clinic with the complaint of painless blurred vision in the right eye. Gonioscopy through a widely dilated pupil revealed a clear, oval, pale brown, semitransparent cyst that was located in the inferotemporal aspect of the iris. The cyst was touching the lens, and the lens was pushed superonasally by the cyst. The iris cyst was treated with selective laser trabeculoplasty laser. A small iris notch emerged at the 8-o'clock position of the pupillary margin. Only mild flare and minimal pigment dispersion were documented postoperatively, which resolved in a few days with a topical corticosteroid. CONCLUSIONS Selective laser trabeculoplasty laser may be considered as a potentially useful and relatively less invasive technique in the treatment of peripheral pigment epithelium iris cysts.

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.

Abstract
PURPOSE Neurofibromatosis 1 (NF1) is an autosomal dominant, multisystem disorder that also effects the eye. Herein, we aimed to investigate the posterior iris surface and ciliary body morphology of NF1 patients by ultrasonic biomicroscopy (UB). MATERIALS & METHODS Nine consecutive unrelated subjects with NF1, and as a control group 25 healthy subjects, were included in the study. All patients underwent ophthalmic examination including visual acuity testing, slit-lamp biomicroscopy, tonometry, gonioscopy (Schaffer classification), and dilated ophthalmoscopy, UB. RESULTS Mean age was 35.1 ± 16.2 (range, 11-57) and 34.5 ± 15.6 (range, 9-60) for NF1 and control groups respectively (p>0.05). Lisch nodules were present in 16 of 18 eyes (88.8%) in NF1 group. Fundoscopic examination of the control group and 15 eyes of NF1 (83.3%) patients was normal, whereas hypoplastic and tilted optic nerve were present in three eyes, and temporally-located bone-spicule-like lesions was present in one eye of the NF1 group. UB revealed ciliary body cyst in 77.7% (14/18) of the eyes among NF1 group, and 8% (4/50) among control group (p<0.05). The mean size of the cysts were 520 ± 191 μ (range, 220-860 μ) and 495 ± 231 μ (range, 300-830 μ) at NF1 and control groups, respectively. Gonioscopic evaluation revealed that 55% of the NF1 patients have an unoccludable anterior chamber angle (Grade 3 or 4), 45% occludable angle (Grade 1 or 2), and 78% irregular pigment patches. However, occludable angle rate was just 4% in the control group, and none of the patients had irregular pigment patches. CONCLUSION The coexistence of ciliary body cysts and NF1, and the effect of these cysts in the eye should be enlightened with further studies.

Abstract
Introduction Plateau iris is recognised as an important cause of primary angle closure glaucoma. The management of this condition generally comprises laser peripheral iridotomy and iridoplasty, to remove any component of relative pupillary block and to widen the iridotrabecular drainage angle respectively. However, plateau iris may be associated with multiple iris cysts at the iridociliary junction, which then presents diagnostic and management problems. Case presentation We present a fifty-three year old Caucasian gentleman with plateau iris associated with peripheral iris cysts, in which the iridotrabecular angle did not widen despite having had both laser peripheral iridotomy and iridoplasty. The patient has remained asymptomatic over 12 months, and is under close follow-up to monitor for signs of glaucoma. Conclusion Plateau iris with iridociliary cysts can be difficult to diagnose and manage. Ultrasound biomicroscopy should be performed on patients with appositional iridotrabecular angle closure on gonioscopy, especially if the angle closure is not relieved with either laser peripheral iridotomy or iridoplasty. Question marks can be raised as to the benefit of laser iridotomy when plateau iris without pupillary block has already been conclusively diagnosed on ultrasound biomicroscopy.

Abstract
PURPOSE OF REVIEW Primary angle closure typically causes acute intraocular pressure rise in the phakic elderly. Alternative diagnoses, however, for which iridotomy is usually ineffective, occur commonly in younger, nonhyperopic, and pseudophakic patients. RECENT FINDINGS High-resolution ultrasonography has advanced our understanding of these entities. Management of platueau iris, present in over half of angle closures with patent iridotomy, may depend on disease stage. Early postoperative pseudophakic patients with myopic shift and narrow angle should be treated with laser capsulotomy for capsular block. Bilateral angle closure is usually due to an offending systemic pharmacologic agent, which must be stopped to resolve the closure. Ciliary body swelling often produces angle closure by blocking the access of aqueous to the anterior chamber, sometimes paradoxically after hypotony. Annular choroidal effusions, difficult to detect without ultrasound, may mimic angle closure. Although cycloplegic and corticosteroid therapy may resolve some entities, pars plana vitrectomy and lensectomy may be necessary to resolve severe ciliary block. We also discuss unique variants of angle closure in patients with retinal disease. SUMMARY Atypical angle closures should always be considered. Careful examination techniques and new technology can detect the mechanisms involved and direct treatment.

Abstract
Argon laser peripheral iridoplasty is a useful procedure to eliminate appositional angle closure resulting from mechanisms other than pupillary block. For those eyes with angle closure originating at an anatomic level posterior to the iris, such as plateau iris, lens-induced angle closure, or posterior segment processes (malignant glaucoma, central retinal vein occlusion, etc.), laser iridotomy by itself may be insufficient to treat the underlying disease mechanism. Argon laser peripheral iridoplasty is often useful in these cases to further open the angle. It can be used to break an acute attack of angle-closure glaucoma and relieve appositional angle closure secondary to plateau iris syndrome, or lens-related angle closure, and to widen the angle prior to argon laser trabeculoplasty. Peripheral location of long-duration, low-power, large spot size laser burns is essential for optimal success.

Abstract
While ultrasonography has been applied to eye examination since the beginning of medical applications of ultrasound, the use of high frequencies is relatively recent in this context. Recent developments since the 1990s have made devices available that are well suited for examining the anterior segment as well as the posterior pole, providing precise data for corneal lesions, iris, chamber angle, and ciliary body abnormalities, and lesions of the papilla and macula.
