The purpose of this report is to provide a comprehensive account of an exceptional case involving the presentation of congenital rubella syndrome (CRS) in a newborn. Furthermore, it aims to document the successful regression of CRS through medical treatment alone. We present the case of a five-day-old infant who was referred to our facility as a CRS case. The patient presented with bilateral white corneal opacity, which was observed shortly after birth. The mother was diagnosed as rubella-positive during pregnancy. Upon the initial examination under anesthesia, both eyes exhibited central white corneal opacity accompanied by large intrastromal cysts. Although a few breaks in Descemet\'s membrane were observed in both eyes, there were no signs of vascularization or the presence of iridocorneal or lenticular-corneal adhesions. After undergoing medical treatment consisting of topical sodium chloride and steroids, the cysts in both eyes completely regressed. Subsequently, the patient underwent penetrating keratoplasty to further address the dense scar. This case enhances our comprehension of ophthalmological complications associated with CRS and provides valuable insights into alternative therapeutic approaches for corneal stromal cysts.

BACKGROUND: The aim of this study was to determine whether anterior scleral thickness (AST) varies significantly between patients with central serous chorioretinopathy (CSCR) versus normal individuals. To validate scleral thickness measurements by ultrasound biomicroscopy (UBM) vis a vis anterior segment optical coherence tomography (ASOCT).
METHODS: This case-control study analyzed 50 eyes of 50 patients with CSCR (cases) and compared it with that of 50 eyes of 50 age- and gender-matched controls. In cases, AST was measured at 1 mm and 2 mm temporal to the temporal scleral spur by ASOCT and UBM. In controls, AST was measured only by ASOCT. In all participants, posterior choroidal thickness (CT) was measured subfoveally, 1 mm nasal and 1 mm temporal to fovea by enhanced depth imaging optical coherence tomography.
RESULTS: The mean AST, as measured by ASOCT among cases and controls was 703.86 μm and 667.54 μm, respectively (P = 0.006). The mean AST by ASOCT and UBM in cases were 703.86 μm and 657.42 μm, respectively (P = 0.001). AST measurement by ASOCT and UBM showed a positive and statistically significant correlation (r = 0.431, P = 0.000). The mean CT among cases and controls was 443.56 μm and 373.88 μm, respectively (P = 0.000). We found a weak positive correlation (r = 0.11) in cases and weaker positive correlation in controls, between CT and AST measured by ASOCT.
CONCLUSIONS: Our findings suggest that AST varies significantly between patients with CSCR versus normal individuals. We found poor agreement of AST when measured by ASOCT and UBM.

BACKGROUND: Tears in Schwartz-Matsuo syndrome are generally confirmed by preoperative ophthalmoscopic examination. A case of Schwartz-Matsuo syndrome with a tear detected by ultrasound biomicroscopy (UBM) and treated by UBM-guided scleral buckling was reported, and its mechanism was analysed.
METHODS: A 40-year-old Chinese man presented with blurry vision and intermittent eye pain in his left eye for three days. The visual acuity of the left eye decreased from 20/20 to 20/40, and the intraocular pressure (IOP) fluctuated dramatically from 24.0 mmHg to 56.7 mmHg at the first visit. Gonioscopy revealed that the chamber angle remained open. A macula-involving inferior retinal detachment extending from 4:30 to 9:30 with no obvious causative break was observed through ophthalmoscopic examination. However, a single small tear was detected at the nonpigmented epithelium of pars plana of the ciliary body at approximately 7-8 o\'clock by UBM. The loss of photoreceptor outer segments and ellipsoid zone and the existence of macular microcysts in the inner and outer nuclear layers were observed in the detached macula by optical coherence tomography. Then, he underwent successful scleral buckling guided by UBM. Three months later, the retina was flat with normal IOP, and the best corrected visual acuity of his left eye gradually improved to 20/25. UBM confirmed the closure of the tear.
CONCLUSIONS: Tear of the nonpigmented epithelium of the ciliary body is a rare condition associated with Schwartz-Matsuo syndrome. UBM plays a key role in detecting occult tears of the nonpigmented epithelium of the ciliary body, guiding scleral buckling surgery, and observing the closure of the tear postoperatively.

BACKGROUND: To report undescribed characteristics of patients with bilateral diffuse uveal melanocytic proliferation (BDUMP) on ultrasound biomicroscopy (UBM) and high-frequency B-scan ultrasonography.
METHODS: 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.

OBJECTIVE: To report, with the aid of original imaging, an unusual differential diagnosis of an iris tumor.
METHODS: A 60-year-old Caucasian man visited our clinic with a large amelanotic iris mass in the left eye in the absence of concomitant extraocular inflammation or neoplastic evidence. The patient reported an ocular trauma caused by a wire 5 years prior to his visit, which resolved after a short course of antibiotic eye drops. Orbital magnetic resonance imaging with contrast enhancement was consistent with an iris tumor; ultrasound biomicroscopy indicated a semi-solid, mid-stromal iris formation continuous with the lens. Surgical inspection was performed. Surgery showed the presence of a hypermature cataract with a fine break in the anterior capsule of the lens covered by the iris surface. The liquefied cortex infiltrated the iris without diffusing into the aqueous humor.
CONCLUSIONS: A so-called morgagnian cataract developed, likely following a penetrating ocular wound. The progressive, slow infiltration of the iris stroma by the crystalline matrix mimicked the appearance of an amelanotic iris tumor.

BACKGROUND: Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) that often affects men over the age of 60. Systemic metastasis of MCL to eyes is rare and intraocular involvement is even rarer, which usually affects the choroid and iris. To the best of our knowledge, ciliary body metastasis of systemic MCL has not been reported.
METHODS: A 59-year-old Han Chinese male with past-history of systemic MCL complained of redness, pain and blurred vision in the left eye. Ocular examination revealed a normal appearance in the right eye, and conjunctival injection, pseudohypopyon and anterior protrusion of peripheral iris in the left eye, all of which were unresponsive to corticosteroid treatments. Ultrasound biomicroscopy (UBM) and B-scan were then performed which detected ciliary body masses in both eyes with no vitreous and retino-choroidal anomalies. Combined liquid-based cytology tests and gene rearrangement assays of the aqueous humor specimen confirmed this to be a B-cell malignancy. Then both eyes were treated with external beam irradiation (40 Gy, delivered evenly in twenty fractions) over a course of one month. Additionally, the left eye received intravitreal methotrexate (MTX) (weekly for the first month, every two weeks for the second month, and monthly thereafter) over a course of twelve months. This therapy eventually led to complete remission of all symptoms in one month and disappearance of the ciliary body masses in twelve months.
CONCLUSIONS: Here we first reported a case of bilateral ciliary body MCL infiltration which was diagnosed by combined liguid-based cytology and gene rearrangement of aqueous humor cells. UBM may serve as a valuable tool in the diagnosis and serial assessments of anterior segment tumors.

A 39-year-old female presented with a painless yellow-pink tumor on her right eye. High-frequency ultrasound imaging revealed an epibulbar lesion with homogenous low internal reflectivity and no evidence of intraocular invasion. The patient underwent excisional biopsy leading to a pathology diagnosis of myxoma. Additional surgical margins as well as adjuvant cryotherapy margins were followed by extensive conjunctival repair. Herein, we report on a conjunctival myxoma with unique ultrasonographic findings.

OBJECTIVE: Hypertensive emergency usually presents to ophthalmologists in the form of hypertensive retinopathy. We present a case of hypertensive emergency that presented as bilateral transient myopic shift due to ciliary body detachment in the absence of any retinal pathology. The purpose of this paper is to showcase another ocular manifestation of hypertensive emergency.
METHODS: A 35 year-old female with a blood pressure of 192/114 mmHg presented to the emergency department with headache and acute onset blurry vision. Computed Tomography (CT) of the head, and lumbar puncture were within normal limits. Visual acuity was counting fingers in the right eye and 6/90 in the left eye, both of which improved to 6/9 with -5.00 diopters spherical correction in the right eye, and -4.75 diopters correction in the left eye. Intraocular pressures were normal. Anterior chambers were shallow, and there were no retinal changes on dilated fundus examination. Enhanced-depth optical coherence tomography (EDI-OCT) showed bilateral increased choroidal thickness and ultrasound biomicroscopy (UBM) showed 360° ciliary body detachment with angle closure. With improved blood pressure control, her ciliary body detachment resolved and her refractive error returned to baseline.
CONCLUSIONS: & Importance: Hypertensive emergency may present with choroidal thickening with anterior ciliary body rotation and detachment. A review of medications is important, as this presentation has also been reported as a rare side effect of sulphonamide drugs. In the absence of retinopathy, UBM and EDI-OCT imaging should be considered in the acutely hypertensive patient presenting with myopic shift.

A 42-year-old male presented to us after an episode of acute anterior human leukocyte antigen (HLA)-B27-associated uveitis, and intraocular pressure (IOP) in the right eye was 4 mmHg. Ultrasound biomicroscopy revealed ciliary body edema with supraciliary effusion. He was on a frequent topical corticosteroid, and oral steroid in addition to receiving a periocular injection depot corticosteroid 20 days back. He was started on treatment with subcutaneous golimumab (GLM). After a month, his IOP in the right eye was 14 mm of Hg with UBM showing resolution of ciliary body edema. GLM can be useful in the management of steroid-resistant cases of HLA B-27-associated ocular hypotony.

OBJECTIVE: To report our diagnostic ultrasound-based approach and surgical strategy in a case of severe blunt trauma with complete hyphema, 270° iris disinsertion, and traumatic subluxated cataract.
METHODS: A 70-year-old male was referred to our hospital for a blunt trauma in his right eye. A complete examination revealed visual acuity consisting in light perception, a complete hyphema, and an intraocular pressure of 45 mm Hg with moderate pain. Our diagnostic approached was ultrasound based with B-scan examination showing some vitreous hemorrhage and ultrasound biomicroscopy showing a large iris disinsertion of 270° with the iris entirely dislocated in the inferior sector of the anterior chamber. The patient was hospitalized and a systemic and topical treatment was started to lower intraocular pressure. Our surgery consisted in a single-step approach with removal of traumatic cataract with scleral fixation of an intraocular lens and iridoplasty.
CONCLUSIONS: In our patient, the single-step surgery, supported by anterior and posterior ultrasound imaging, achieved a satisfactory anatomical and functional outcome.
