Fuchs heterochromic iridocyclitis-associated glaucoma: a retrospective comparison of primary Ahmed glaucoma valve implantation and trabeculectomy with mitomycin C.

Background: The aim of this study was to compare the safety and efficacy of primary trabeculectomy with mitomycin C and Ahmed glaucoma valve (AGV) implantation in patients with Fuchs heterochromic iridocyclitis (FHIC)-related glaucoma, a rare complication of an uncommon form of uveitis. Methods : In this retrospective comparative case series, 26 FHIC-associated glaucoma patients received trabeculectomy (n=12) or an AGV (n=14). Primary outcome measures were surgical success, defined as intraocular pressure (IOP) ≤21 mmHg, decreasing ≥20% from baseline, and no secondary glaucoma surgery. Secondary outcome measures were the number of glaucoma medications, complications, best corrected visual acuity (BCVA), and IOP. Results: The follow-up was 34.0±17.7 months in patients that received trabeculectomy and 33.4±18.6 months in AGV (P= 0.837). The cumulative probability of success rate was 41.7% for trabeculectomy and 85.7% for AGV, with no significant difference in complications (P>0.05). The IOP in patients that received trabeculectomy dropped from 23.4±3.3 mmHg to 21.6±5.2 mmHg at the final visit (P= 0.041). In patients that received AGV, the IOP decreased from 24±7.8 to 17.1±2.6 mmHg (P= 0.003). The number of glaucoma medications at baseline were 3.3±0.5 in those that received trabeculectomy and 3±0.6 in those that received AGV (P=0.233), and decreased to 2.4±1.0 (P=0.008) and 1.7±0.6 (P=0.002), respectively. BCVA was equal in both groups and did not change (P>0.05). Conclusion: Primary AGV had a higher success rate than trabeculectomy, with patients also needing fewer medications for the management of FHIC-associated glaucoma.

Impacto do grau de uveíte em diferentes tipos de úlceras de córneas em cães submetidos ao enxerto pediculado de conjuntiva bulbar - 34 casos / Impact of uveitis score on different types of corneal ulcers in dogs subjected to the bulbar conjunctival pedicle graft - 34 cases

O presente trabalho objetivou avaliar os resultados de 34 olhos submetidos ao enxerto conjuntival pediculado (ECP) em ceratites ulcerativas profundas (n=5), em ceratites ulcerativas com colagenólise (n=2), descemetocele (n=7), perfuração corneal (n=15) e prolapso de íris (n=5). Os impactos do grau de uveíte e da integridade da córnea foram correlacionados com presença e ausência de visão por tabelas de contingência. Raças braquicefálicas foram acometidas em 91,11% dos casos. O número de córneas consideradas perfuradas [20/34 (58,82%)] foi maior que o de córneas íntegras [14/34 (41,17%)]. Ao 50º dia de pós-operatório, o número de olhos visuais que apresentavam córneas íntegras previamente às cirurgias (n=13) não diferiu significativamente dos olhos com córneas perfuradas (n=12) (P=0,05). Avaliações relativas ao grau de uveíte, revelaram que a metade dos casos foi considerada severa [17/34 (50%)] e na outra metade as uveítes foram consideradas discretas. Dos 17 casos que apresentaram uveíte severa, oito recuperaram a visão. Já nos 17 olhos onde a uveíte foi considerada leve, 15 mantiveram a visão ao final do período de avaliação. Apesar de a integridade da córnea não se correlacionar com a severidade da uveíte (P=0,48), constatou-se que o número de olhos visuais com uveíte discreta foi significativamente maior que os olhos com uveíte severa (P=0,006). Neste estudo, a taxa geral de sucesso visual após ECP foi de 73,52% e a integridade da córnea não exerceu impacto significativo sobre a manutenção da visão. Todavia, olhos acometidos por uveítes severas apresentaram menor chance de recuperar a visão.(AU)

The present study aimed to evaluate the results of 34 eyes of dogs presenting deep corneal ulcer (n=5), colagenolytic corneal ulcer (n=2), descemetocele (n=7), corneal perforation (n=15), and iris prolapse (n=5) that were corrected by the bulbar conjuntival pedicle graft (CPG). The uveitis score and the corneal integrity were correlated with the presence or absence of vision by contingency tables. Brachycephalic breeds accounted for 91.11% of all cases. The number of perforated corneas [20/34 (58.82%)] were higher than the non-perforated ones [14/34 (41.17%)]. At post-operative day 50, the number of visual eyes with non-perforated corneas before surgery (n=13) did not differ significantly from the eyes with perforated corneas (n=12) (P = 0.05). In half of the cases, uveitis score was considered severe [17/34 (50%)], and in the other half, mild. Eight out of 17 eyes classified with severe uveitis regained vision. In 17 eyes where uveitis score was considered mild, 16 regained vision at the end of the study. Although corneal integrity was non-correlated with the uveitis score (P = 0.48), the number of visual eyes scored with mild uveitis were significantly larger than the eyes with severe uveitis (P = 0.006). In this study, the overall success visual rate after CPG was 73,52% % and the corneal integrity did not play an important role regarding maintenance of vision. However, eyes presenting severe uveitis score had less chance to regain vision.(AU)

Comparison between Outcomes of Vitrectomy in Granulomatous and Nongranulomatous Uveitis.

PURPOSE: The aim of this study was to compare the outcomes of vitrectomy in granulomatous uveitis and nongranulomatous uveitis insufficiently managed by immunosuppressive therapy. METHODS: Thirty-eight eyes with granulomatous uveitis and 17 eyes with nongranulomatous uveitis that underwent vitrectomy for ocular complications between July 2006 and August 2012 were reviewed retrospectively. Visual acuity and ocular inflammation scores before and 6 months after surgery were compared. Patients treated with vitrectomy alone and those in whom vitrectomy was combined with phacoemulsification were analyzed separately. RESULTS: The mean visual acuity improved significantly both in granulomatous and nongranulomatous uveitis. In granulomatous uveitis, the mean inflammation scores decreased significantly both in the anterior segment and in the posterior segment. In nongranulomatous uveitis, the mean inflammation score in the posterior segment decreased significantly, although it did not change in the anterior segment. CONCLUSION: Vitrectomy was effective for treating ocular complications both in granulomatous uveitis and nongranulomatous uveitis, with favorable outcomes of improved visual acuity and decreased uveitis activity.

Long-term efficacy of deep sclerectomy in Posner-Schlossman syndrome.

The Posner-Schlossman syndrome (PSS) is an elusive disease that can lead to serious consequences such as glaucomatous damage. Deep sclerectomy has been proven thus far to be the most effective surgical intervention to keep intraocular pressure (IOP) elevation under control compared with other surgical techniques, because it presents the least amount of postoperative complications. The aim of this case report is to demonstrate the efficacy of deep sclerectomy with T-Flux and the long-lasting effects that persist after 7 years in an eye affected by PSS. This case report demonstrates that an intervention of deep sclerectomy can lead to excellent results in terms of visual acuity as well as IOP lowering early in the history of the patient affected by PSS so that it can preclude establishment of glaucomatous damage.

Implantation of iris-claw Artisan intraocular lens for aphakia in Fuchs' heterochromic iridocyclitis.

Implantation of iris-claw Artisan intraocular lens (IOL) is a surgical option for correction of aphakia; however, these IOLs have not been used in eyes with uveitis including Fuchs' heterochromic iridocyclitis (FHI) due to possible risk of severe postoperative intraocular inflammation. In the case reported here, we secondarily implanted an Artisan IOL in a 28-year-old man with FHI who had aphakia with no capsular support due to a previous complicated cataract surgery. Enclavation was easily performed and no intraoperative complication was noted. Postoperative course was uneventful with no significant anterior chamber inflammation during 12 months of follow-up. Although there were few deposits on the IOL surface, the patient achieved a best-corrected visual acuity of 20/20 without developing glaucoma or other complications. Therefore, Artisan IOL may be considered for correction of aphakia in patients with FHI. However, studies on large number of patients are required to evaluate safety of the procedure.

Small-incision cataract surgery in patients with Fuch's heterochromic iridocyclitis.

INTRODUCTION: Fuch's heterochromic iridocyclitis (FHI) is often complicated by cataract formation. OBJECTIVE: To assess the results of small-incision cataract surgery (SICS) in FHI and to study the effect of preoperative factors on postoperative vision. MATERIALS AND METHODS: Sixty-three eyes of 59 patients with Fuchs heterochromic iridocyclitis who had SICS with in-the-bag implantation of intraocular lens (IOL) were evaluated retrospectively; and the primary and secondary outcome measures evaluated were the postoperative vision and complication rate. RESULTS: The mean age was 39.22±4.95 years. The mean pre-operative vision was 0.75±0.24 Log MAR units. The mean final vision was 0.27±0.10 Log MAR units (P=less than 0.001). At the final follow-up, 84.1% of the patients had a final Snellen's vision of 6/12 or better. The mean follow-up period was 12.06±2.06 months. The causes of corrected distance visual acuity (CDVA) worse than 6/60 were vitreous opacities, posterior keratic precipitates (KPs), glaucoma, persistent uveitis and cystoid macular edema (CME). Preoperative factors like iris atrophy (P=0.973), heterochromia (P=0.10) and vessels in angle (P=0.074) did not have a significant effect on the final vision. On the contrary, vitreous opacities (P=0.002) and posterior KPs (P=0.009) had a significant effect on the final visual outcome. CONCLUSION: SICS with in-the-bag implantation of IOL in patients with Fuch's heterochromic iridocyclitis resulted in good visual outcomes. SICS in complicated cataracts can be performed in rural settings and eye camps with minimal instrumentation, obviating the need for referral to tertiary care centers. Pre-operative factors like vitreous opacities and posterior KPs have a significant effect on the final vision.

A case of congenital corneal anesthesia with hypopyon in china.

PURPOSE: To report a case of congenital corneal anesthesia (CCA) associated with hypopyon and tactile hypoesthesia. METHODS: Case report. RESULTS: A 3-year-old girl presented with redness and mild photophobia in the left eye accompanied by corneal ulcer, hypopyon, and corneal neovascularization. Corneal sensation was reduced bilaterally. She exhibited an absence of normal response to painful stimuli. She also had extensive ulceration of the lateral borders and tip of the tongue. The left corneal biopsy revealed negative cultures for bacteria and fungi. She was treated with human amniotic membrane transplantation in the left eye. The response to treatment was good. CONCLUSION: This is the first case of CCA reported in China. CCA is often misdiagnosed as infectious keratitis. Amniotic membrane transplantation is effective in repairing the severe corneal ulcer which may be associated with CCA.

Amsler-Verrey sign during cataract surgery in Fuchs heterochromic uveitis.

Fuchs heterochromic uveitis (FHU) in its classic presentation is a unilateral, chronic, low grade, often asymptomatic anterior uveitis. It is characterized by a classic triad of iris heterochromia, cataract and keratic precipitates. Neovascularization of the iris and the anterior chamber (AC) angle (radial and circumferential) occurs in 6-22% of cases. This angle and iris new vessels can sometimes lead to a characteristic filiform haemorrhage and formation of hyphaema after AC paracentesis and is a hallmark of FHU known as Amsler-Verrey sign. This haemorrhage has been previously associated with trivial trauma, mydriasis, applanation tonometry, gonioscopy, or it may occur spontaneously. In the setting of cataract surgery it has been previously reported with the use of a Honan balloon. We report a case of cataract and FHU where the Amsler-Verrey sign developed intraoperatively during a phacoemulsification procedure. To the best of our knowledge, this is the first documented report of this sign occurring intraoperatively during cataract surgery.

[The first experience in clinically using a PASCAL laser photocoagulator (OptiMedica, USA)].

A new PASCAL laser photocoagulator (OptiMedica, USA) was clinically tested. A total of 38 laser interventions were performed in 38 eyes with diabetic retinopathy (n = 25), peripheral retinal dystrophy (n = 2), retinal ruptures (n = 2), hemophthalmos (n = 3), primary open-angle glaucoma (n = 5), and ectopic pupil (n = 1). An example of successful use of the new laser unit for pupilloplasty for the ectopic pupil is given.

Fuchs' heterochromic uveitis associated with retinal break or dialysis.

BACKGROUND: Three cases of Fuchs' heterochromic uveitis (FHU) are described, 2 with peripheral retinal breaks and 1 with retinal dialysis. METHODS: Argon laser photocoagulation was applied around the breaks and the dialysis. RESULTS: The retinal breaks and dialysis were successfully photocoagulated. INTERPRETATION: Thorough inspection of the fundus, including the peripheral retina, is important in patients with FHU to exclude a retinal break or a dialysis.

Fibrinous anterior uveitis due to cysticercus cellulosae.

PURPOSE: To report a case of fibrinous anterior uveitis due to cysticercus cellulosae in anterior chamber. DESIGN: Retrospective, interventional case study. METHODS: Patient underwent complete ophthalmic and systemic evaluation with relevant investigations. Viscoexpression of anterior chamber cysts were done under general anaesthesia. RESULTS: A 10-year-old male child presented as unilateral fibrinous iridocylitis with secondary glaucoma. Two cysts of cysticercus cellulosae were seen after control of inflammation. Complete resolution of uveitis occurred once the cysts were removed by viscoexpression. CONCLUSION: Cysticercus cellulosae can present as fibrinous anterior uveitis with secondary glaucoma. Removal of the cyst can cause complete resolution of uveitis.

Outcomes of phacoemulsification and in-the-bag intraocular lens implantation in Fuchs' heterochromic iridocyclitis.

PURPOSE: To evaluate the visual outcomes and complications of phacoemulsification (PE) and posterior chamber intraocular lens implantation, (PC IOL) in patients with Fuchs heterochromic iridocyclitis (FHIC). SETTING: Private clinic and an academic hospital. METHODS: In this noncomparative interventional case series, existing data for 41 eyes of 40 consecutive patients clinically diagnosed with FHIC and cataract were studied retrospectively. Scleral tunnel PE and in-the-bag IOL implantation were performed in all cases. Preoperative and postoperative visual acuities and intraoperative and postoperative complications were evaluated. RESULTS: Twenty-four male and 16 female patients aged 12 years to 70 (SD) (mean 35 +/- 12 years) were operated on and followed for 17.8 +/- 8.7 months. Preoperatively, best corrected visual acuity (BCVA) was less than 20/40 in all patients, which improved to 20/40 or better after surgery. Twenty-two eyes (53.6%) achieved BCVA of 20/20. The major cause of postoperative visual acuity less than 20/20 was vitreous haze. There were no major intraoperative complications. Postoperatively, mild anterior chamber fibrin reaction occurred in 4 patients (9.7%), IOL deposits occurred in 11 eyes (26.8%), and decentration was observed in 1 eye. During follow-up, 6 eyes (14.6%) developed posterior capsule opacification requiring a neodymium:YAG (Nd:YAG) laser capsulotomy. There was 1 case of clinical cystoid macular edema that resolved with medication. There were no cases of posterior synechias, postoperative glaucoma, or retinal detachment. CONCLUSION: Phacoemulsification with PC IOL implantation is a safe procedure with good visual outcomes in patients with FHIC and cataract.

Melanocitoma de cuerpo ciliar sintomático: glaucoma melanocitomalítico / Symptomatic ciliary melanocytoma: Melanocytomalytic Glaucoma

Caso Clínico: Mujer de 33 años de edad con masa pigmentada, asintomática en ángulo iridocorneal de ojo derecho originada en cuerpo ciliar. Diagnóstico de sospecha de melanocitoma de cuerpo ciliar se decidió observación. Después de 36 meses de seguimiento presenta dolor, reacción inflamatoria y aumento incontrolable de presión intraocular que se diagnostica de glaucoma melanocitomalítico. Se realiza escisión del tumor mediante iridociclectomía «ab-externo» y el estudio histopatológico demostró melanocitoma necrótico. Discusión: El melanocitoma de cuerpo ciliar es un tumor pigmentado benigno, poco frecuente que puede presentar extensión a cámara anterior. El diagnóstico diferencial se realiza fundamentalmente con melanoma de cuerpo ciliar, que implica un diferente tratamiento y pronóstico(AU)

Case Report: A 33 year-old female with an asymptomatic pigmented mass in the iridocorneal angle of her right eye, arising from the ciliary body is presented. Ciliary body melanocytoma was suspected and conservative management recommended. After 36 months of follow-up the patient developed pain, inflammatory reaction and uncontrollable ocular hypertension, which was diagnosed as melanocytomalytic glaucoma. Tumor was removed by external iridecyclectomy and the histopathologic findings revealed necrotic melanocytoma. Discussion: Ciliary body melanocytoma is a rare benign pigmented tumor that may present extension to the anterior chamber. Differential diagnosis mainly includes ciliary body melanoma, which carries a different prognosis and treatment(AU)

[Heterochromia of the Iris after t-PA and Gas Injection of Sulfur Fluoride]. / Irisheterochromie nach rtPA- und Gasinjektion.

BACKGROUND: Are changes in iris colour and retinal pigment epithelium after t-PA and gas injection and subsequent vitreous haemorrhage caused by blood cells, or is this a toxic effect? CASE: A 81-year old female presented for vitrectomy with a persistent vitreous haemorrhage two months after t-PA and gas injection because of subretinal macular haemorrhage. Sonographic control revealed attached retina. The examination disclosed a new heterochromia of the iris with a change from blue to green-brown. A discrete anterior chamber flare and blood cells were found. Subsequent vitrectomy revealed a thick, rubber-like haemorrhage in the vitreous with suspect pigmentation. A change in retinal pigmentation was also evident. CONCLUSION: The cause for the heterochromia and the change in pigmentation of the retinal pigment epithelium remained unclear. It may have been a consequence of the persistent bleeding with iron apposition on the iris. A toxic effect of t-PA has to be discussed which led to the alteration in pigmentation.

The effect of pars plana vitrectomy in the management of Fuchs heterochromic cyclitis.

PURPOSE: Fuchs heterochromic cyclitis (FHC) is characterized by a unilateral chronic iridocyclitis of insidious onset and uncertain cause. Our aim was to evaluate the effect of vitreous surgery in patients with FHC and clinically significant visual symptoms caused by inflammatory vitreous debris. METHODS: This study was a review of 12 eyes of 12 consecutive patients with FHC who underwent pars plana vitrectomy for visually significant vitreous opacities. Cataract extraction with posterior chamber lens implantation had been performed on four eyes preoperatively. Four eyes had a concomitant lensectomy for cataracts, and one had a surgical posterior capsulotomy. Visual and anatomic data were recorded before surgery and for at least 6 months after surgery. RESULTS: Visual acuity improved in all patients from an average logMAR of 0.57 to 0.007 (P = 0.0004) and by more than 2 Snellen lines in 8 of 12 of the eyes (P < 0.05). Symptoms of floaters resolved in all 11 patients in whom they were a symptom. Vitreous haze was cleared completely from an average Nussenblatt grade of 1.7 to 0 after 1 week (P = 0.0001). CONCLUSIONS: Pars plana vitrectomy is a safe and effective treatment for the visual symptoms associated with FHC and can be combined safely with a lensectomy if required.

Fuchs' heterochromic iridocyclitis: a review of 26 cases.

UNLABELLED: Fuchs' heterochromic iridocyclitis (FHI), an unusual form of uveitis of unknown etiology, is frequently misdiagnosed. PURPOSE: To report the analysis of 26 patients (27 eyes) with FHI who were diagnosed and observed over a period of 1-7 years (mean: 3.42 +/- 2.2 years). METHODS: Ocular and systemic examinations were performed on all patients. RESULTS: The most common presenting symptom was visual deterioration (42.3%); one patient was affected bilaterally. Characteristic keratic precipitates (100%), cataracts (77.8%), and heterochromia (70.4%) were the major signs. Eleven eyes (40.7%) required cataract surgery. At the initial examination, four eyes (14.8%) had glaucoma, and no new cases of glaucoma developed during the follow-up period. One eye required filtration surgery. Vitrectomy was performed in two eyes (7.4%) because of vitreous opacities. Most patients (73.0%) did not require active treatment; pre- and postoperative anti-inflammatory treatment for cataract extraction was performed successfully to minimize the risk of inflammation. No severe uveitis was seen in any patient after surgery, but visual acuity did not improve greatly after cataract extraction; 54.5% eyes had visual acuity better than 20/40 before surgery, and 45.4% postoperatively. CONCLUSION: Posterior capsule opacification, glaucoma, and vitreous opacity were the major obstacles to visual rehabilitation after cataract surgery in patients with this type of uveitis.

Hyphema after peribulbar anesthesia for cataract surgery in Fuchs' heterochromic iridocyclitis.

PURPOSE: To describe an unusual ocular sign in one patient with Fuchs' heterochromic iridocyclitis at cataract surgery. METHODS: We describe a patient with Fuchs' heterochromic iridocyclitis and cataract who developed a 1 mm hyphema observed two minutes after peribulbar anesthesia for cataract surgery. RESULTS: The patient was found to have an equivalent of the Amsler-Verrey sign. It appeared after peribulbar anesthesia and before any instrument touched the globe. It did not interfere with surgery and disappeared completely by day 2. CONCLUSION: The appearance of a hyphema after peribulbar anesthesia in Fuchs' heterochromic iridocyclitis is an unusual sign that may have the same pathophysiology as the Amsler-Verrey sign.
