Abstract Background To report five cases of acute drug-induced angle closure and transient myopia with ciliochoroidal effusion and to analyze angiographic findings of these cases. Methods This study is an observational case series. Five patients with acute drug-induced angle closure and transient myopia with ciliochoroidal effusion were examined by fluorescein angiography, indocyanine green angiography (ICGA) and ultrasound biomicroscopy (UBM). Results Five patients presented with bilateral visual loss and ocular pain after intake of topiramate, methazolamide, phendimetrazine tartrate or mefenamic acid. All patients showed elevated intraocular pressure (IOP) with shallow anterior chamber and myopic shift from − 0.5 to − 17.0 diopters (D). UBM showed ciliochoroidal effusions with diffuse thickening of the ciliary body in all cases. Rapid normalization of IOP and decrease of myopic shift occurred in all patients after discontinuing the suspected drugs. We classified the ICGA findings into 2 major signs (hypofluorescent dark spots, hyperfluorescent pinpoints) and 3 minor signs (diffuse choroidal hyperfluorescence, early hyperfluorescence of choroidal stromal vessel, and leakage and dilated retinal vessels). Conclusions The pathogenesis of acute drug-induced angle closure and transient myopia with ciliochoroidal effusion may be idiosyncratic reaction of uveal tissue to systemic drugs. Accumulation of extravascular fluid in the ciliochoroidal layer had a major role in the pathogenesis. ICGA could be a useful method to examine the pathophysiology of this condition by imaging of the choroidal layer.

<b><i>Introduction:</i></b> Ultrasound biomicroscopy (UBM) is the only widely used method for the evaluation of anterior uveal melanoma (AUM). <b><i>Objective:</i></b> Documentation of regression of AUM treated with ruthenium-106 (Ru-106) plaque types CCB and CCC using UBM. <b><i>Methods:</i></b> This single institution-based retrospective case series involved 10 Caucasian patients with AUM followed after brachytherapy with UBM from January 2014 until February 2019. The largest prominence of the tumor perpendicular to the sclera or the cornea (including scleral/corneal thickness) (<i>D</i>) and the largest basal dimension (<i>B</i>) were measured in millimeters with UBM for all patients prior to the brachytherapy and at 4-month interval follow-up. Tumor regression was calculated as a percentage of decrease in the initial <i>D</i> and <i>B</i> values. <b><i>Results:</i></b> The study involved 10 patients with a mean age of 64.4 years (yr) (range 46–80 yr). <i>D</i> ranged from 1.82 to 5.5 mm (median 2.99 mm) and <i>B</i> from 2.32 to 12.38 mm (median 4.18 mm). The apical radiation dose in all patients was 100 Gy. The median follow-up was 42.02 months. Regression for <i>D</i> was 21.11 ± 13.66%, 31.09 ± 14.66%, and 34.92 ± 19.86% at 1st, 2nd, and 3rd year of the follow-up, respectively, while for <i>B</i> it was 21.58 ± 16.05%, 28.98 ± 17.71%, and 32.06 ± 18.96%, respectively. Tumor recurrence was documented in 2/10 patients. <b><i>Conclusion:</i></b> The major regression of AUM, treated with Ru-106 plaque types CCB and CCC, was documented in the first 2 years after brachytherapy in our study group. In the following years, only minimal regression was documented that warns of the need for close monitoring and active search for local recurrences.

Abstract Background To report undescribed characteristics of patients with bilateral diffuse uveal melanocytic proliferation (BDUMP) on ultrasound biomicroscopy (UBM) and high-frequency B-scan ultrasonography. Case presentation Two of four participants presented with worsening bilateral vision after previously diagnosed primary pulmonary or ovarian carcinoma. The other two patients were diagnosed with lung carcinoma after presentation with BDUMP. All patients had ciliary body nevi-like lesion in combination with iris or ciliary body cysts, and uveal thickening on UBM. Focally elevated choroidal nevi-like lesion and exudative retinal detachment with choroidal thickening were detected with B-scan ultrasonography. Conclusions Our case series demonstrates the uveal characteristics of patients with BDUMP based on high-frequency B-scan ultrasonography and UBM. Ultrasonographic findings are crucial in the diagnosis of BDUMP because it is occult in nature.

Purpose: To evaluate the safety and efficacy of a novel approach to implant Ex-Press mini shunt via the pars plana under a scleral flap in pseudophakic or aphakic, vitrectomized patients with secondary refractory glaucoma. Methods: A prospective interventional case series of three patients with secondary glaucoma after pars plana vitrectomy. Intraocular pressure was not controlled by silicone oil removal, if the patient was siliconized, nor the maximum medical treatment. Ex-Press mini shunt via the pars plana was implanted. We evaluated the control of intraocular pressure and the development of intraoperative and postoperative complications. Results: During 1-year follow-up, control of intraocular pressure was achieved; 14, 15, and 15 mmHg at the 3 months, and 15, 15, and 16 mmHg at the 6 months in our three cases without antiglaucoma treatment and 16, 16, and 18 with single antiglaucoma medication at 1 year. Blebs were posterior and diffuse. No complications were encountered intraoperatively or postoperatively. Ultrasound biomicroscopy showed suprachoroidal posterior lake of fluid as an additional filtration route without any choroidal or retinal complication. Conclusion: Implantation of Ex-Press mini shunt via the pars plana in aphakic or pseudophakic, vitrectomized eyes is a promising, safe, and effective technique in patients with secondary glaucoma.

Objective. In a group case series, the clinical characteristics of congenital membranous cataract in children were studied to establish a system of classification and determine the surgical method suited for each type. Methods. Children (18 eyes) with congenital membranous cataract were examined by slit lamp, ultrasound biomicroscopy, and operating microscopy to classify cataracts. The clinical characteristics of congenital membranous cataract and its feature related to the surgical method were analyzed. Results. Five major types of congenital membranous cataracts were classified. All of the surgeries were successful. Anterior and posterior capsulorhexis was performed using Klöti RF capsulotomy tips. The capsular flap was removed, and anterior vitrectomy was performed using a vitrectomy cutter. Postoperative complications included posterior capsule opacification in 16.7% of the patients. Conclusion. Ultrasound biomicroscopy was used successfully to classify congenital membranous cataracts prior to surgery. Anterior and posterior capsulorhexis was performed using Klöti RF capsulotomy tips, and capsulectomy was performed using a vitrectomy cutter. These were effective techniques and should be considered for congenital membranous cataract removal surgery. This trial is registered with registration number chiCTR-OOC-17010913.

Purpose To evaluate the long-term morphologic changes in the anterior segment structures after nonpenetrating filtering surgery (NPFS) supplemented with 5-fluorouracil (5-FU) and no scleral implant using ultrasound biomicroscopy (UBM). Methods Thirteen eyes of 13 consecutive patients who underwent NPFS with intraoperative 5-FU under the conjunctiva and the scleral flap and no implant were evaluated in an observational nonrandomized, consecutive case series study conducted 2 years postoperatively. Patients were assessed for the presence of a subconjunctival filtering bleb, the volume of an intrascleral cavity, and a suprachoroidal hypoechoic area. The intraocular pressure (IOP) was measured preoperatively and postoperatively at the time of UBM. Results The IOP decreased significantly (p=0.01) from 24±7.6 mmHg to 13.7±4.1 mmHg. In most patients (69.2%), the postoperative IOP decreased at least 30% from the preoperative value without medications and in 84.6% with medication. UBM showed a subconjunctival empty space in 92.3% of eyes. In 84.6% of patients, an intrascleral cavity was seen, the mean volume of which was 1.68 mm3 (range, 0–4.07). We found a negative correlation between the height, width, and volume of the intrascleral lake and the IOP. In 92.3% of eyes, a hypoechoic area in the suprachoroidal space also was seen. Conclusions UBM showed a filtering intrascleral cavity, subconjunctival filtering bleb, and a suprachoroidal space after NPFS supplemented with 5-FU under the conjunctiva and the scleral flap without an implant.
