Concurrent ciliary body detachment in patients presenting with serous choroidal detachment following glaucoma surgery.

PURPOSE: To examine the rate of ciliary body detachment in patients with choroidal detachment following glaucoma surgery and its effect on the clinical course, management, and prognosis. METHODS: A prospective observational case-series study. Patients with choroidal detachment following glaucoma surgery in 2018-2019 were included. All underwent complete ophthalmological examination and ultrasound biomicroscopy for evaluation of the presence and extent of ciliary body detachment. Follow-up examinations including ultrasound biomicroscopy scans were performed at 1 week, 1 month, 3 months, and 6 months. RESULTS: Eight patients (8 eyes) were enrolled, 4 male and 4 female, of mean age 72 years (range 60-83). Five patients underwent trabeculectomy with mitomycin C (0.02%), which was combined with phacoemulsification cataract extraction in one; two underwent Ahmed glaucoma valve implantations, and one underwent ab-interno Xen45 gel stent implantation with mitomycin C (0.02%). The mean intraocular pressure was 26.0 ± 7.65 mmHg preoperatively, dropping to 6.9 ± 2.64 mmHg on first postoperative day one. Mean time from surgery to diagnosis of choroidal detachment was 11.6 ± 5.73 days. Ciliary body detachment was identified by ultrasound biomicroscopy in all patients, ranging between one and four quadrants. All patients were treated with topical steroids and cycloplegics; three (37.5%) received oral steroids. No surgical intervention for the choroidal or ciliary body detachments was indicated. CONCLUSIONS: In this real-world prospective study, concurrent ciliary body detachment was identified in all patients who presented with choroidal detachment following glaucoma surgery. This observation may deepen our understanding of the mechanism underlying the hypotony that is often seen after glaucoma surgery.

Tuberculous ciliary body granuloma initially diagnosed as bullous retinal detachment: a case report.

BACKGROUND: Ocular tuberculosis is a relatively rare extrapulmonary manifestation of tuberculosis. This vision-threatening disease is extremely challenging to diagnose, particularly because it can mimic other diseases. We report a case of tuberculous ciliary body granuloma initially diagnosed as bullous retinal detachment. CASE REPORT: A 52-year-old female presented with bullous retinal detachment in her left eye, and ultrasound biomicroscopy (UBM) verified the presence of a lesion with ciliary body granulomatous inflammation. The T-SPOT was positive, and the purified protein derivative (PPD) test was strongly positive (diameter of 20 mm). Following the administration of oral anti-tuberculosis regimen combined with prednisone, the retina gradually became reattached, the ciliary body granuloma became significantly reduced in size, and the visual acuity of the patient noticeably improved. CONCLUSIONS: Tuberculous ciliary body granulomas can cause bullous exudative retinal detachment and can be diagnosed with UBM. Early and full-course anti-tuberculosis treatment (ATT) combined with corticosteroid therapy can improve the patient prognosis.

UVEAL EFFUSION ASSOCIATED WITH LOCALIZED SCLERODERMA BECAUSE OF SCLERAL FIBROSIS.

BACKGROUND/PURPOSE: To report a case of uveal effusion associated with localized scleroderma because of scleral collagen fibrosis. Partial-thickness sclerectomy treatment was successful in acquiring the resolution of the uveal effusion. METHODS: Case report. RESULTS: A 44-year-old Chinese woman with known localized scleroderma visited the retinal clinic complaining of insidious onset blurring of vision in both eyes for 8 months. The best-corrected visual acuity was 20/200. Ophthalmoscopy revealed apparent inferior bullous serous retinal detachments in the right eye. Optical coherence tomography showed subretinal fluid and folds of the retinal pigment epithelium layer in both eyes. B-scan ultrasonographic image of the right eye confirmed a 360-degree serous retinal detachment in the right eye accompanied with increased thickness of the ocular wall. Ultrasound biomicroscopy of the anterior segment detected a shallow ciliary body detachment in the right eye. Fluorescein angiography and indocyanine green angiography demonstrated the leopard-spot pattern in all phases. Partial-thickness sclerectomy treatment was successful in acquiring the resolution of the uveal effusion. Histopathologic examinations of the sclera flaps revealed scleral collagen fibrosis. CONCLUSION: This clinicopathologic report first describes a patient with localized scleroderma and scleral collagen fibrosis, resulting in uveal effusion that responded to partial-thickness sclerectomy.

Bilateral diffuse uveal melanocytic proliferation: Report of a rare Ocular Paraneoplastic Syndrome.

Bilateral diffuse uveal melanocytic proliferation is a rare paraneoplastic disorder where bilateral blindness is caused by uveal thickening, serous retinal detachment, and rapid cataract formation. Several different malignancies have been associated with bilateral diffuse uveal melanocytic proliferation, but ovarian carcinoma in women and lung and pancreatic carcinoma in men are the most common. The underlying mechanism is thought to be related to a an endogenous factor wich regulates the proliferation of uveal melanocytes. We present the case of a 75-year-old man with bilateral diffuse uveal melanocytic proliferation secondary to pulmonary adenocarcinoma.

A prospective, population-based, surveillance (BOSU) study of uveal effusion syndrome in the UK.

PURPOSE: To determine the incidence and demographic profile of uveal effusion syndrome (UES), and to describe the visual and anatomic outcome following deep sclerectomy or vortex vein decompression. METHODS: The British Ophthalmological Surveillance Unit (BOSU) mails reporting cards monthly to 1149 senior UK ophthalmologists, who are requested to report incident cases of specified rare diseases. UES was included in the reporting system from October 2009 to October 2011. If UES was identified, ophthalmologists were mailed a questionnaire to collect anonymized clinical data at baseline, and 12 months after. RESULTS: Over 2 years, 29 cases were reported. Two cases were duplicates and 12 failed to meet the eligibility criteria. Of the 15 eligible cases, age ranged from 11 to 91 years (mean 62) and nine were males (60%). Ten patients were hypermetropic; three had an axial length of 19.0 mm or less. Estimated annual incidence was 1.2 per 10 million population. Seven cases were managed nonsurgically, including observation (one case), topical steroids (two cases), systemic steroids (three cases), and cyclodiode laser (one case). Eight cases (11 eyes) underwent full-thickness sclerectomy; the elevated flap was retained in four. The sclera was noted to be thick and rigid during surgery in five cases. Median preoperative visual acuity was 6/18, changing slightly to 6/21.5 at final review, with three eyes showing complete anatomic response, five showing some improvement, and three failing to respond. CONCLUSIONS: UES is extremely rare. It occurs in a range of ages, but is most common in middle-aged, hypermetropic men. Visual acuity can be materially reduced. The most commonly used surgical treatment in the UK is deep sclerectomy.

Congenital ectropion uveae (CEU) with refractory glaucoma: Early trabeculectomy saves vision.

We report the case of congenital ectropion uveae in a 10-year-old boy with intractable unilateral glaucoma but no systemic association. Glaucoma in congenital ectropion uveae is often poorly responsive to medial therapy and requires surgical intervention. Satisfactory results are possible if diagnosis is established early and timely surgery performed, as was the case in our patient.

Unusual non-nanophthalmic uveal effusion syndrome with histologically normal scleral architecture: a case report.

BACKGROUND: To report an unusual case of non-nanophthalmic uveal effusion syndrome (UES) with histologically normal sclera but responsive to scleral resection. CASE PRESENTATION: A73-year-old man presented with a bullous retinal detachment without ciliochoroidal detachment on funduscopic examination of the right eye. The axial length of both eyes was normal. Extensive investigations for possible causes of exudative retinal detachment were performed with unremarkable results except for choroidal hyperpermeability on indocyanine green angiography (ICGA). Ultrasound biomicroscopy (UBM) revealed scleral thickening with peripheral choroidal elevation leading to the diagnosis of UES. Partial thickness sclerectomy and sclerotomy was performed resulting in complete retinal reattachment, reduction of choroidal hyperpermeability on ICGA and improvement of visual acuity. However, histological studies of the excised sclera revealed no scleral architectural changes or abnormal deposits. CONCLUSIONS: The diagnosis of UES in non-nanophthalmic eyes is challenging. Thorough systemic and ocular investigations are critical to rule out other etiologies. UBM can be helpful to evaluate scleral thickness and anterior choroid in equivocal cases. Our case was unique in that, although the sclera was thick, no abnormal microscopic scleral architecture could be identified. Misdiagnosis may lead to different surgical procedures such as vitrectomy resulting in unfavorable outcomes.

Uveal and capsular biocompatibility of a new hydrophobic acrylic microincision intraocular lens.

PURPOSE: To evaluate uveal biocompatibility and capsular bag opacification of a new hydrophobic acrylic microincision intraocular lens (IOL) in comparison with a commercially available 1-piece hydrophobic acrylic IOL. SETTING: John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA. DESIGN: Experimental study. METHODS: Eight New Zealand rabbits underwent bilateral phacoemulsification and implantation of the preloaded Nanex multiSert IOL in one eye and a commercially available preloaded lens (AcrySof IQ in UltraSert, model AU00T0) in the contralateral eye. A slitlamp examination was performed weekly for 4 weeks. The rabbits were then killed humanely and their globes enucleated. Capsular bag opacification was assessed from the Miyake-Apple view, and the eyes were subjected to histopathologic evaluation. RESULTS: Postoperative inflammatory reactions were similar between the test and control eyes in the 8 New Zealand rabbits. The mean postmortem central posterior capsule opacification (PCO) was 0.93 ± 0.73 in the test group and 1.19 ± 0.53 in the control group. The mean postmortem peripheral PCO was 1.75 ± 0.92 in the test group and 2.06 ± 0.77 in the control group. Central and peripheral PCO scores were not statistically different between the test and control groups (P = .41 and P = .35, respectively, 2-tailed t test: paired 2-sample for means). CONCLUSIONS: A new 1-piece hydrophobic acrylic microincision IOL incorporating an ultraviolet-ozone treatment on the posterior surface performed similarly to a commercially available 1-piece hydrophobic acrylic IOL in terms of uveal and capsular biocompatibility in the rabbit model. To our knowledge, this is the first hydrophobic acrylic microincision IOL to demonstrate similar PCO performance when compared with a conventional, commercially available IOL.

Iris and ciliary body cysts and phakic intraocular lenses.

Phakic intraocular lenses are used to correct refractive errors. The procedure is predictable and potentially reversible. The procedure is not free of complications though. The occurrence of iris cyst after implantation of a phakic intraocular lens was not described previously in the literature. We describe two cases of iris cysts in the presence of a phakic intraocular lens; the first case describes a cyst which was not present prior to the anterior chamber phakic intraocular lens implantation. The second case describes a hidden iris cyst that affected the posterior chamber phakic intraocular lens position and lead to glaucoma.

Bilateral diffuse uveal melanocytic proliferation secondary to thyroid carcinoma.

We present a rare case of a bilateral diffuse uveal melanocytic proliferation (BDUMP), which occurred secondary to recurrence of carcinoma of thyroid in a 79-year-old gentleman who was initially misdiagnosed to have age related macular degeneration and/or chronic central serous chorioretinopathy. In spite of being treated with anti-VEGF injection and photodynamic therapy there was progressive loss of vision. Multimodal imaging like autoflourescence, infrared imaging, fluorescein angiography, indocyanine angiography, and OCT angiography helped us in clinching the final diagnosis.

Non-prescription cold and flu medication-induced transient myopia with uveal effusion: case report.

BACKGROUND: To report a case of non-prescription cold and flu medication-induced transient myopia with uveal effusion. CASE PRESENTATION: Bilateral high intraocular pressure, shallow anterior chambers, uveal effusion, and a myopic shift were encountered in a 39-year-old Chinese male 1 night after taking a non-prescription flu medicine three times than the recommended dose. Ultrasound biomicroscopy (UBM) showed bilateral ciliochoroidal effusions, disappearance of the ciliary sulcus, closure of the angle of the anterior chamber, and anterior displacement of the lens-iris diaphragm. Treatment with aqueous suppressants was given. Within a week, the uncorrected vision restored, and the myopia had disappeared. UBM revealed major resolution of the ciliochoroidal effusions in both eyes, deepening of the anterior chamber, return of the lens-iris diaphragm to a more posterior position. CONCLUSIONS: Overdose of non-prescription cold and flu medication may cause bilateral uveal effusions inducing acute angle-closure glaucoma and acute myopia.

Partial thickness sclerectomy and intravitreal anti-VEGF therapy for intractable uveal effusion syndrome.

PURPOSE: To report a case series of three patients with intractable uveal effusion syndrome (UES), treated with partial thickness sclerectomy and intravitreal anti-VEGF therapy. METHODS: Three patients with intractable UES were included. All patients underwent intravitreal anti-VEGF therapy to facilitate resolution of uveal effusion. The concentrations of IL-1ß, IL-6, IL-8, IL-10, IL-12p70, TNF and VEGF in aqueous humor were measured. RESULTS: After the last intravitreal injection, all three eyes had total resolution of the chorioretinal detachment or subretinal fluid. One eye experienced improvement in visual acuity. All patients were free from recurrence during the follow-up period. Aqueous IL-6, IL-8 and VEGF concentrations were elevated in all cases. CONCLUSIONS: Our current data provided the evidence that VEGF was increased in eyes with intractable UES and anti-VEGF therapy was effective, suggesting that partial thickness sclerectomy and intravitreal anti-VEGF therapy could be a new choice for intractable UES.
