Ultrasound biomicroscopic features of iris retraction syndrome.

BACKGROUND AND OBJECTIVES: To examine anatomic relationships of anterior and posterior chamber structures in iris retraction syndrome using ultrasound biomicroscopy. PATIENTS AND METHODS: Four eyes of four patients with iris retraction syndrome were imaged using high-frequency, high-resolution, anterior segment ultrasound biomicroscopy. In two patients, scans were obtained before and after medical therapy. RESULTS: Three patients presented with iris retraction configuration and one with iris bombe. In the latter case, iris bombe converted to iris retraction and back to iris bombe with the administration and later withdrawal of aqueous suppressants. Ciliochoroidal effusion was present in all eyes. CONCLUSIONS: Ciliochoroidal effusion is a constant feature of iris retraction syndrome. The hypotony associated with this disorder may result in part from aqueous hyposecretion related to ciliary body detachment. Ultrasound biomicroscopy is a useful aid in the diagnosis and follow-up of eyes with iris retraction syndrome.

Angle-closure glaucoma in nanophthalmos.

Two patients had nanophthalmos with uveal effusion and angle-closure glaucoma. They were treated with a method based on the use of the laser, not only to perform iridotomy but to shrink the iris stroma, which appears to open the anterior chamber angle even without iridotomy. Additionally, we introduced three factors that may be diagnostic of nanophthalmos.

Ciliochoroidal effusions after neodymium:YAG posterior capsulotomy: association with pre-existing glaucoma and uveitis.

Two patients with a history of glaucoma and a propensity for uveitis developed ciliochoroidal effusions following Nd:YAG laser posterior capsulotomy. Both patients experienced a waxing and waning course with eventual resolution of symptoms after a steroid regimen. The ciliochoroidal effusions were presumed to be secondary to uveitis induced by the YAG laser surgery. The role of glaucoma, previous surgeries, and an open posterior capsule is uncertain but may have predisposed these patients to ciliochoroidal detachment. We advise caution in performing YAG posterior capsulotomy in patients with glaucoma and a known propensity for uveitis.

Angle-closure glaucoma complicating ciliochoroidal detachment.

Acute angle-closure glaucoma complicating ciliochoroidal detachment developed in eight eyes of six patients. The clinical presentation was uniform: extremely shallow central anterior chamber depth, flat peripheral anterior chamber, closed angle, and elevated intraocular pressure (IOP). There were three patients with uveal effusion syndrome, two with posterior scleritis, and one with an arteriovenous malformation. Cycloplegia, along with aqueous suppressants and corticosteroids, successfully resolved the acute glaucoma in all eyes. This rare, secondary glaucoma must be differentiated from primary angle-closure glaucoma, because the treatment is markedly different. Although primary angle-closure glaucoma is treated with miotics and peripheral iridectomy, such therapy may worsen the glaucoma in eyes with angle-closure glaucoma due to a ciliochoridal detachment.

Study of acute intraoperative suprachoroidal hemorrhage.

Acute intraoperative suprachoroidal hemorrhage or effusion (AISH) was studied in a prospective manner over the past three years. In a general cataract surgery population of 2,523 patient eyes, 15 (0.6%) experienced an AISH. Results of a specific surgical management technique are presented. Surgical control of the AISH consisted of immediate closure of the incision and application of pressure directly to the eye. This tamponades the effusion or hemorrhage, which allows coagulation and completion of the case. There was no attempt to drain the suprachoroidal space. All cases were completed the same day, usually within an hour. The postoperative visual acuities were quite good--20/40 or better in 93% of cases. Factors contributing to AISH were 4+ brunescent nuclear sclerosis, the large incision used with nucleus expression extracapsular cataract extraction, and the combination of anticoagulation and systemic vascular disease.

Choroid plexus papillomas of the III ventricle in infants. Report of three cases.

The III ventricle is an uncommon location for choroid plexus papilloma at any age. We describe three new cases of choroid plexus papillomas of the III ventricle (CPPs). All children were boys under 4 months of age and all presented with increased intracranial pressure, hydrocephalus and macrocephaly. The three were examined by preoperative computed tomography (CT) and ultrasonography. Two of them were investigated with magnetic resonance imaging (MRI). The first case was treated with a right corticofrontal transventricular approach and subtotal resection, so that he required a second operation through a transcallosal approach. In the other two cases a transcallosal approach was used. Two children needed permanent ventriculo-peritoneal shunts. The average follow-up of 4.3 years has revealed no neurological deficits in any case. The timing of and the need for shunting are major considerations. Clinical and imaging follow-up (CT and/or ultrasonography) are very helpful in controlling postoperative hydrocephalus and subdural effusion, avoiding unnecessary shunting in many cases. The operative approaches, transcortical and transcallosal, are discussed.

An ultrasound biomicroscopic analysis of angle-closure glaucoma secondary to ciliochoroidal effusion in IgA nephropathy.

Immunoglobulin A nephropathy is a common glomerulonephritis of unknown cause. Episcleritis, scleritis, anterior uveitis, and keratoconjunctivitis sicca have been associated with this disease. We diagnosed angle-closure glaucoma secondary to ciliochoroidal effusion in a patient with IgA nephropathy confirmed by biopsy. High-frequency ultrasound biomicroscopy was used to determine internal relationships of angle structures and to follow changes with treatment. Supraciliary effusion undetected by B-scan ultrasound and retinal examination was easily imaged by ultrasound biomicroscopy. Glaucoma mechanisms included forward rotation of the ciliary processes, which caused direct angle closure in a manner similar to plateau iris. Ultrasound biomicroscopy showed that cycloplegia improved this mechanism by retracting the ciliary processes, but angle closure secondary to forward iris bowing from pupil block remained. Iridectomy was performed and immediately opened the angle. Ultrasound biomicroscopy proved a useful method of defining mechanisms and a helpful guide to treatment in this type of glaucoma.

Noninvasive closure of a persistent cyclodialysis cleft.

BACKGROUND: A persistent post-traumatic cyclodialysis cleft can result in substantial visual loss due to subchoroidal effusion and macular folds with hypotony. A method of closure is needed. PATIENTS AND METHODS: After other methods had been tried, the authors used transscleral YAG laser cyclophotocoagulation in three consecutive patients with 20 applications in two rows of ten applications, 2 to 3 mm behind the limbus, at a power setting of 6 J, with a defocus setting of 9. RESULTS: The cleft was closed with restoration of normal intraocular pressure and recovery of visual function in all patients. CONCLUSION: Transscleral YAG laser cyclophotocoagulation is a simple, effective, noninvasive method of closing a persistent traumatic cyclodialysis cleft, which may make invasive surgical closure unnecessary.

Surgical management of the idiopathic uveal effusion syndrome.

Twenty-three eyes of 20 patients with idiopathic ciliochoroidal effusion underwent quadrantic partial-thickness sclerectomies without decompression of the vortex veins. The mean postoperative follow-up interval was 41 months (range, 6-86 months). Resolution of subretinal and/or supraciliochoroidal fluid occurred within 6 months in 19 eyes (83%) after one procedure and in 22 eyes (96%) after one or two procedures. The mean interval to reattachment for the 19 successfully treated eyes with nonrhegmatogenous retinal detachment (RD) was 2.4 months compared with an average preoperative detachment duration of 18.5 months (P = 0.0005). Recurrences were seen in 23% of eyes; all resolved spontaneously or with a single reoperation. Final visual acuity was improved by two or more lines in 13 eyes (56%), stable in 8 (35%), and worse in 2 (9%). The efficacy of this surgical technique supports the hypothesis that an abnormality of transscleral protein transport plays a primary pathophysiologic role in this disorder.

Ultrasound biomicroscopic evaluation of ciliochoroidal effusion after laser treatment.

We evaluated ciliochoroidal effusion (CE) by ultrasound biomicroscopy (UBM) following diode endophotocoagulation at the end of the vitreoretinal surgery. The aim of our study was to assess any differences in the CE morphology following diode endophotocoagulation or transpupillary krypton photocoagulation, and to demonstrate the influence of diabetes and intravitreal surgery on CE formation. Sixty-six consecutive patients were divided in to four groups. Twenty-nine patients with proliferative retinopathy underwent transpupillary krypton photocoagulation; 11 diabetic patients underwent vitreoretinal surgery and diode endophotocoagulation; 18 nondiabetics underwent vitreoretinal surgery and diode endophotocoagulation; 8 consecutive nondiabetic patients were the control group and underwent vitreoretinal surgery, without laser treatment. UBM was performed in the four groups before and after laser treatment, if performed. We determined, by UBM, not only the presence, but also the thickness of CE. CE was present in all the patients treated by laser, diabetics and nondiabetics, and its thickness was not correlated with the number of laser spots (p = 0.28). CE was seen ultrasonically in all the patients undergoing transpupillary photocoagulation or endophotocoagulation, regardless of diabetes and surgical trauma.

[Vis-à-tergo. Uveal effusion and expulsive hemorrhage in cataract surgery].

BACKGROUND: Since introduction of the self-sealing incision for cataract surgery it has been possible to avoid serious complications due to an acute rise in intraocular pressure. Chorioidal effusion (CE) and expulsive hemorrhage (EH) should be determined and treated differently. PATIENTS AND METHODS: The incidence of vis-à-tergo in our patients was 1.7%. CE was ascertained in 0.1%; in one case, the operation had to be interrupted. EH occurred in one patient (0.03%) in the last 3,000 cataract operations. Differential diagnoses were made by ultrasonic examination. RESULTS: Operations in CE cases were completed without further complications. However, in one case the operation was interrupted and the procedure was completed on the following day. A 63-year-old woman with EH had a massive rise in intraocular pressure directly after lens implantation with a peripheral capsular rupture. Postoperatively, a chorioidal hemorrhage in two quadrants, including the macula, was found. One week after surgery a posterior sclerotomy was performed with simultaneous infusion into the anterior chamber with BSS. The nearly complete chorioidal reattachment was achieved after drainage of the liquified blood. Visual acuity has improved to 0.5. CONCLUSION: Vis-à-tergo in modern cataract surgery only rarely results in an ES or EH. Also, in an EH there is an incomplete form. After an adequate therapeutic procedure good visual function can be expected.
