Outcome of cataract surgery in children with presumed trematode-induced granulomatous anterior uveitis.

PURPOSE: To examine the 6-month visual outcomes and complications following cataract surgery in patients with persumed trematode induced granulomatous anterior uveitis. SETTING: Assiut university hospital, Assiut, Egypt. DESIGN: This is a retrospective non comparative case series study. METHODS: Patients presenting with significant cataract secondary to uveitis caused by trematode induced anterior chamber granuloma were included in this study. Cases with active anterior uveitis, within the last 3 months preceding surgery, and those with a history of trauma, were excluded from this study. Data collected included demographic characteristics, history of the condition including when uveitis started, treatment received and history of other health conditions that may be relevant to uveitis.Complete opthalmologic examination including assessment of best corrected visual acuity (BCVA) and OCT macula, if possible, were done. These was repeated 1 week, 1 month, 3 months and 6 months after surgery. Specular microscopy was performed preoperatively and 3 months after surgery. Patients underwent cataract surgery with posterior chamber intra ocular lens and statistical analysis was performed to compare preoperative and postoperative BCVA and corneal endothelial cell counts. Postoperative complications were recorded. RESULTS: Five eyes of 5 patients were included in the study. All study eyes showed improvement in the post-operative visual acuity. A statistically significant improvement was observed in VA in the sixth postoperative month compared to the baseline measurements (p = 0.004). No statistically significant difference was observed between the preoperative and postoperative endothelial cell counts (p = 0.696). Cystoid macular edema did not occur as a postoperative complication. CONCLUSION: Visual outcomes of cataract surgery in eyes with persumed trematode induced granulametous anterior uveitis are favorable. No sight threatening complication was observed in our series.

The Value of Laser Flare Photometry as a Monitoring Tool for Uveitis. / Der Stellenwert von Laser-Flare-Messungen zur Verlaufsbeurteilung von Uveitiden.

Laser flare (LF) photometry (P) is used to quantify the protein concentration in the aqueous humor, and therefore assess the blood-aqueous humor barrier. LFP is more reliable than the clinical assessment of the Tyndall effect, and is thus especially useful in the follow-up of uveitis patients. In active uveitis, LFP correlates well with the anterior chamber cell grading. Various studies have shown that high LF values are associated with an increased risk of uveitic complications, such as macular edema, glaucoma, and posterior synechiae. LFP can also be used to assess the response to anti-inflammatory treatments as well as the optimal timing and selection of the surgical technique for intraocular surgeries.

Clinical results of ab interno trabeculotomy using the trabectome in patients with uveitic glaucoma.

IMPORTANCE: To evaluate the safety and efficacy of ab interno trabeculotomy (AIT) (trabecular ablation) with the trabectome in patients with uveitic glaucoma. BACKGROUND: Traditional glaucoma filtration surgeries in the uveitic patient population come with a higher risk of complications such as failure and hypotony. DESIGN: Retrospective observational cohort study. PARTICIPANTS: All patients diagnosed with uveitic glaucoma were included in this study. Patients were excluded if they have less than 12 months of follow-up. METHODS: All patients who received AIT alone or combined with phacoemulsification. MAIN OUTCOME MEASURES: Major outcomes include intraocular pressure (IOP), number of glaucoma medications and secondary glaucoma surgery, if any. Kaplan-Meier method was used for survival analysis and success was defined as IOP ≤21 mmHg, at least 20% IOP reduction from baseline for any two consecutive visits after 3 months, no additional glaucoma medications, and no secondary glaucoma surgery. RESULTS: A total of 45 eyes, 45 patients, with an average age of 52 years were included in the study. The majority were Japanese (40%) and underwent AIT alone (71%). IOP was reduced from 29.2 ± 8.0 to 16.7 ± 4.6 mmHg at 12 months (P < .01*), while the number of glaucoma medications was reduced from 4.0 ± 1.0 to 2.5 ± 1.6 (P < .01*). Survival rate at 12 months was 91%. Six cases required secondary glaucoma surgery and no other serious complication were reported. CONCLUSIONS AND RELEVANCE: The trabectome AIT procedure appears to be effective in reducing IOP in uveitic glaucoma patients. Although no statistically significant difference was found in the number of glaucoma medications, a decreasing trend was found.

Case report of secondary pigment dispersion glaucoma, recurrent uveitis and cystoid macular oedema following inadvertent implantation of an intraocular lens into the ciliary sulcus following cataract surgery.

BACKGROUND: This case highlights the important sequelae that can occur following the inadvertent implantation of a single-piece intraocular lens into the ciliary sulcus during cataract surgery; secondary pigment dispersion glaucoma, recurrent anterior uveitis and macular oedema. CASE PRESENTATION: A 67-year-old lady underwent routine left cataract surgery in a separate unit but subsequently attended our eye casualty with recurrent hypertensive anterior uveitis. She was found to have secondary pigment dispersion glaucoma as the intraocular lens had been inadvertently placed into the ciliary sulcus. She underwent a trabeculectomy to control the intraocular pressure and initially settled well but 12 months later developed persistent anterior segment inflammation and macular oedema. She subsequently had the intraocular lens removed and the macular oedema was treated successfully with intravitreal Bevacizumab. CONCLUSIONS: We provide a summary of the evidence and a discussion over the management options available in managing such a difficult case.

Sarcoid-like reaction in a patient with uveitis and underlying cancer.

PURPOSE: Sarcoidosis is a granulomatous disease of unknown etiology. Occasionally, triggering causes are identified, such as neoplasms, and they are termed sarcoid-like reactions, which may appear in any sarcoidotic target tissue. Choroidal metastases appear as part of widespread metastatic disease or as the first suggestion of neoplastic disease. They can also be a part of the differential diagnosis of a spectrum of inflammatory eye diseases. We present a case in which a lung carcinoma, pulmonary and eye sarcoid-like reactions, and choroidal metastasis take place in the same patient. CASE REPORT: A 60-year-old male with a past history of pulmonary sarcoidosis and associated anterior uveitis was diagnosed with a lung carcinoma with no regional lymph nodes extension, so that the resection surgery was performed without additional systemic treatment. At the same time, he complained of visual acuity loss and pain in his right eye. An intense ocular inflammatory reaction and a choroidal mass compatible with metastasis were identified. A vitrectomy with an accompanied histological exam of the lesion was deemed inconclusive. Ocular symptoms progressively worsened showing mass growth, and as a result, an enucleation was performed and the histological study subsequently revealed metastasis from his lung carcinoma. CONCLUSION: Sarcoid-like reactions may be due to incipient malignancies. Any diagnosis of sarcoidosis requires ruling out other diseases that can produce secondary sarcoid-like reactions. In addition, any choroidal mass suggestive of metastasis requires exclusion of metastatic disease even in the absence of clinical signs indicating tumor extension.

Trabeculectomy ab interno with the Trabectome® as a therapeutic option for uveitic secondary glaucoma.

PURPOSE: Treatment of secondary glaucoma in uveitis patients is challenging. Owing to the young age of these patients, sufficient lowering of the intraocular pressure (IOP) is essential to prevent progression of visual field loss. However, because of the chronic inflammatory stimulus, filtration surgery has an increased risk of failure, especially in patients who have previously undergone surgery. Therefore, minimally invasive glaucoma surgery is a valuable alternative. METHODS: The clinical records of 24 consecutive patients with uveitic secondary glaucoma who underwent trabeculectomy ab interno with the Trabectome® at the Eye Center of the Albert-Ludwigs University of Freiburg between June 2009 and June 2014 (registered in the Freiburg trabectome database) were retrospectively analyzed. The general baseline information for each patient included age, gender, glaucoma type, ocular medication and current IOP. The postoperative IOP and number of antiglaucomatous medications were recorded at each visit. Statistical analyses were performed using the Kaplan-Meier estimator and Dunnett's t-test. RESULTS: The mean IOP before surgery was 31 ± 6.7 mmHg (median 32 mmHg). Both the IOP and the number of medications significantly decreased over the various follow-up intervals after trabeculectomy ab interno with the Trabectome®. Patients with follow-ups continuing past one year showed an IOP-reduction of approximately 40 % and a medication number reduction from 2 to 0.67. The failure rate (necessitating further glaucoma surgery) was N = 3 (12.5 %) patients. CONCLUSIONS: Trabeculectomy ab interno with the Trabectome® is a minimally invasive and effective method for controlling IOP in uveitic secondary glaucoma.

Recurrent symptomatic intraocular pressure spikes during hemodialysis in a patient with unilateral anterior uveitis.

BACKGROUND: The relationship between intraocular pressure (IOP) changes and hemodialysis has been evaluated for several decades. However, no report on an IOP rise in uveitis patients during hemodialysis has been previously documented. This report describes the case of an uveitis patient with repetitive IOP spikes associated with severe ocular pain during hemodialysis sessions, which resolved after glaucoma filtering surgery. CASE PRESENTATION: A 47-year-old male with diabetes and hypertension had complained of recurrent ocular pain in the left eye during hemodialysis sessions. A slit-lamp examination showed diffuse corneal epithelial edema with several white keratic precipitates and inflammatory cells (Grade 3+) in the anterior chamber of the left eye. No visible neovascularization or synechiae were visible on the iris or angle. Topical glaucoma eye-drops and intravenous mannitol before hemodialysis did not prevent subsequent painful IOP spikes in the left eye. At the end of hemodialysis, IOP averaged ~40 mmHg. After trabeculectomy with mitomycin C in the left eye, his IOP stabilized in the low-teens (range, 10-14 mmHg) and no painful IOP spikes occurred during hemodialysis over the first postoperative year. CONCLUSION: We present a case of recurrent painful IOP spikes during hemodialysis in a patient with unilateral anterior uveitis unresponsive to conventional medical treatment prior to hemodialysis. To our knowledge, this is the first case report of repetitive symptomatic IOP rise during hemodialysis in an uveitic glaucoma patient. This case highlights the importance of the awareness of the possibility that IOP may rise intolerably during hemodialysis in uveitis patients with a compromised outflow facility.

Argon laser photocoagulation for treatment of presumed trematode-induced granulomatous anterior uveitis in children.

BACKGROUND/AIMS: To assess the safety and efficacy of argon laser photocoagulation as a new modality for the treatment of presumed trematode-induced granulomatous anterior uveitis (PTGAU) in children. METHODS: Forty-eight eyes of 48 children with PTGAU with pearl-like nodule(s) in the anterior chamber were included in this prospective non-randomised controlled clinical trial. The patients were divided into two groups: those in Group A (23 eyes) were treated with one session of argon laser applied to the anterior chamber nodules and those in Group B (25 eyes) received medical treatment in the form of topical steroid and cycloplegic eye drops with trans-septal triamcinolone injections. All cases were followed up for 3 months with measurement of visual acuity (VA), assessment of the anterior chamber reaction and measurement of the pearl-like nodule size. RESULTS: In Group A, 22 eyes (95.65%) showed regression of the pearl-like nodules with resolution of the anterior chamber reaction (flare and cells) and improvement in visual acuity from 0.52±0.12 to 0.06±0.08 logMAR (p<0.001). Such improvement was maintained within the 3-month follow-up period. In Group B, 23 eyes (92%) showed initial regression of the granulomas, which was maintained in only 14 eyes (56%),with nine eyes experiencing recurrence after 3 months of follow-up. CONCLUSION: Argon laser photocoagulation is a safe and effective novel treatment for PTGAU with pearl-like nodules in the anterior chamber in children. Larger studies with longer follow-up periods are needed to confirm these results.

Long-term outcomes of small-incision cataract surgery in patients with uveitis.

Purpose: To evaluate the long-term outcomes of manual small-incision cataract surgery (MSICS) in eyes with uveitis. Methods: Patients who underwent MSICS for uveitic cataract from 2009 to 2019 were retrospectively evaluated. Visually significant cataract and presence of less than five cells per high-power field in the anterior chamber for a minimum of 3 months were the prerequisites for surgery. Patients with follow-up less than 9 months were excluded. Results: After exclusion, 283 eyes of 264 patients were evaluated. The mean age of patients was 44.3 ± 11.3 years. The mean follow-up duration was 22 ± 11.5 months. The mean surgical time was 11.2 ± 3.2 min. One hundred and seventy-two eyes (60.8%) had anterior uveitis, 78 (27.5%) had posterior uveitis, and 33 (11.7%) had panuveitis. At the final follow-up, 253 eyes (88.4%) had corrected distance visual acuity (CDVA) better than 0.6 log of minimum angle of resolution (LogMAR) unit. The final endothelial cell counts were significantly (analysis of variance [ANOVA], P = 0.001) lower in eyes with human leukocyte antigen (HLA)-B27-associated uveitis and in eyes with idiopathic anterior uveitis. Patients on systemic corticosteroids had significantly better (P = 0.031) final visual acuity than those without preoperative corticosteroids. Recurrent uveitis (43.8%), Posterior capsule opacification (PCO) (19.4%), glaucoma (8.5%), cystoid macular edema (CME; 13.5%), and Epiretinal membrane (ERM) (5.6%) were the frequent complications. A significantly worse (ANOVA, P = 0.001) visual prognosis was seen in patients with Vogt-Koyanagi-Harada disease (VKH), sarcoidosis, acute posterior multifocal placoid pigment epitheliopathy (APMPPE), and serpiginous choroiditis. Conclusion: MSICS is safe in most cataracts due to uveitis and results in improvement in CDVA at 9 months. Posterior capsule opacification, macular edema, persistent uveitis, etiology of uveitis, and use of preoperative steroids significantly influenced the visual outcome.

Uveitis preceding Crohn's disease by 8 years.

We report the clinical history of a child affected by Crohn's disease in which uveitis precedes intestinal involvement by years and occurs with the atypical features of anterior chronic inflammation complicated by unilateral optic disc edema, rather than recurrent anterior uveitis with sudden onset which has been more widely reported in inflammatory bowel diseases. The uveitis onset occurred 8 years before symptoms of the primary intestinal disease, while in inflammatory bowel diseases the intestinal inflammation typically precedes ocular symptoms, and ocular inflammation only occasionally precedes inflammatory involvement of the bowel.

Outcome of peripheral iridotomy in subjects with uveitis.

BACKGROUND/AIMS: Peripheral iridotomy (PI) may be required in subjects with uveitis to manage iris bombe, seclusio pupillae and primary angle closure glaucoma. The aim of this study was to identify risk factors for failure of both laser and surgical PIs in patients with uveitis and determine survival durations. METHODS: Retrospective study of subjects with a history of uveitis undergoing yttrium-aluminium-garnet (YAG) laser or surgical PI at Auckland District Health Board over an 11-year period. Failure of PI was defined as loss of patency or recurrence of iris bombe. A mixed effects shared frailty model was constructed with PI nested within eyes nested within patients, to examine time to failure. RESULTS: 131 PIs were performed in 52 eyes of 39 subjects during the study period (111 YAG PIs and 20 surgical PIs). Median age at time of PI was 46.6 years and 60.5% of subjects were female. HLAB27 positive uveitis was the most common diagnosis (25.6% of subjects). Median survival time was 70 days for YAG PI and 11.0 years for surgical PI. On multivariate analysis, younger age at time of PI (HR 0.933, p<0.001) and iris bombe (HR 2.180, p=0.046) were associated with risk of failure. Surgical PI was associated with a lower risk of failure (HR 0.151, p<0.001) compared with YAG PI. Glaucoma developed in 19 eyes (36.5%), of which 13 required glaucoma surgery. CONCLUSION: Surgical PI had longer survival than YAG PI, and should be considered in subjects presenting with iris bombe and in young subjects with uveitis.

Delayed infectious keratitis in a patient with radial keratotomy and floppy eyelid syndrome treated with simple interrupted stitches. / Queratitis infecciosa tardía en paciente con queratotomía radial y síndrome del párpado flácido tratado con puntos sueltos.

A 55-year-old male presented with an infectious keratitis in his left eye, affecting one of the incisions of the radial keratotomy he had undergone thirty-four years ago. Suturing the incision with two simple interrupted stitches was key to the resolution of the infection. Floppy eyelid syndrome was also found in this patient. Could this act as a risk factor for infectious keratitis in radial keratotomy? To our knowledge, this is the first reported case describing the association between both conditions, and the second reported case where sutures have been used as an adjuvant treatment in these types of cases.

Comparison of tepoxalin, carprofen, and meloxicam for reducing intraocular inflammation in dogs.

OBJECTIVE: To compare effects of orally administered tepoxalin, carprofen, and meloxicam for controlling aqueocentesis-induced anterior uveitis in dogs, as determined by measurement of aqueous prostaglandin E(2) (PGE(2)) concentrations. ANIMALS: 38 mixed-breed dogs. PROCEDURES: Dogs were allotted to a control group and 3 treatment groups. Dogs in the control group received no medication. Dogs in each of the treatment groups received an NSAID (tepoxalin, 10 mg/kg, PO, q 24 h; carprofen, 2.2 mg/kg, PO, q 12 h; or meloxicam, 0.2 mg/kg, PO, q 24 h) on days 0 and 1. On day 1, dogs were anesthetized and an initial aqueocentesis was performed on both eyes; 1 hour later, a second aqueocentesis was performed. Aqueous samples were frozen at -80 degrees C until assayed for PGE(2) concentrations via an enzyme immunoassay kit. RESULTS: Significant differences between aqueous PGE(2) concentrations in the first and second samples from the control group indicated that aqueocentesis induced uveitis. Median change in PGE(2) concentrations for the tepoxalin group (10 dogs [16 eyes]) was significantly lower than the median change for the control group (8 dogs [16 eyes]), carprofen group (9 dogs [16 eyes]), or meloxicam group (9 dogs [16 eyes]). Median changes in PGE(2) concentrations for dogs treated with meloxicam or carprofen were lower but not significantly different from changes for control dogs. CONCLUSIONS AND CLINICAL RELEVANCE: Tepoxalin was more effective than carprofen or meloxicam for controlling the production of PGE(2) in dogs with experimentally induced uveitis. Tepoxalin may be an appropriate choice when treating dogs with anterior uveitis.

The characteristics of Posner-Schlossman syndrome: A comparison in the surgical outcome between cytomegalovirus-positive and cytomegalovirus-negative patients.

This retrospective observational study aims to report the clinical characteristics and surgical results in eyes with Posner-Schlossman syndrome (PSS), and compare these outcomes between cytomegalovirus (CMV)-positive and -negative eyes.We reviewed the medical records of 21 consecutive immunocompetent patients clinically diagnosed with PSS between the years 2010 and 2018. Aqueous humor was collected from all the affected eyes to detect if CMV was present, and polymerase chain reaction (PCR) was performed using the herpesvirus family primers.The average period between the initial PSS attack and aqueous humor sampling at our institute was 9.3 years. Out of the 21 patients, 62% were CMV-positive. Regardless of CMV status, the mean intraocular pressure (IOP), mean deviation (MD), and central corneal endothelium cell (CEC) density, at the initial examination at our institute were already significantly worse in the affected eyes than in the unaffected eyes (all P values < .05). The average visual acuity (VA) was only significantly worse in the CMV-positive group (P = .02). Out of all the patients, those that were CMV-positive had undergone more glaucoma surgeries (P = .056). Fourteen patients underwent either a trabeculectomy (TRAB) or a trabeculotomy (LOT), and their IOP significantly reduced following surgery (P < .001). In 85.7% of those that had surgery, their IOP was successfully lowered to less than 20 mm Hg.Long-lasting PSS causes a decrease in VA, MD, and the CEC density. A prompt diagnosis is required, and an appropriate treatment plan should be formulated. In those patients with PSS that develop uncontrolled glaucoma, both TRAB and LOT may be effective in controlling IOP.

Treatment of presumed trematode-induced granulomatous anterior uveitis among children in rural areas of Egypt.

PURPOSE: The purpose of this study is to evaluate the efficacy of systemic antiparasitic medications alone or in combination with surgical aspiration in management of presumed trematode-induced anterior uveitis in children. PATIENTS AND METHODS: Prospective case series. Children who presented with anterior chamber (AC) granuloma were included in the study. All patients received antiparasitic treatment and after 2 weeks; patients were divided based on their clinical improvement in terms of the baseline granuloma area into two groups: group A (<2.5 mm2) who continued on antiparasitic medications only (n = 15) and group B (≥2.5 mm2) who underwent surgical aspiration (n = 15). Basic demographics data, visual acuity (VA), corneal thickness, granuloma area and AC activity (cells and flare) were recorded and analysed. Systemic work-up including stool and urine analysis, full blood count, chest X-ray and schistosomiasis titre were performed. RESULTS: Thirty eyes of 30 patients were included in the study with a mean age of 13.4 ± 2.42 years. All patients were male. Patients were examined and followed at Mansoura Ophthalmic Center, Mansoura University. Both groups showed statistically significant improvement in VA, AC activity, corneal thickness and granuloma area (p-value < 0.001), which was achieved with medical treatment only in group A. However, in group B granuloma required aspiration and did not recur after that. CONCLUSION: Presumed trematode-induced AC granuloma is common among children living in the rural areas of Egypt. Antiparasitic medication alone was found to be effective for small-sized granulomas. Surgical aspiration is an effective adjuvant procedure to treat large-sized ones.

Complications of cosmetic iris implants.

Cosmetic intraocular iris implants for the purpose of changing iris color have recently been developed; however, little is known about their safety. We report a patient who had bilateral implantation of colored silicone iris implants solely for cosmetic reasons. The rapid development of uveitis, corneal decompensation, and ocular hypertension resulted in the need for explantation of the implants. Placement of these devices should require specific medical indications and meticulous surgery with early and long-term evaluation.

Combined Ahmed valve and phacoemulsification with intraocular lens implantation under infliximab in refractory uveitic glaucoma.

PURPOSE: To evaluate the outcome of combined Ahmed glaucoma valve (AGV) and phacoemulsification with posterior chamber intraocular lens implantation under infliximab in refractory uveitic glaucoma (UG). METHODS: In this prospective interventional case series, 26 eyes of 26 patients with refractory UG underwent surgery under intravenous infliximab. The success rate was defined as intraocular pressure (IOP) 5 to 21 mm Hg with or without antiglaucoma medications (AGM), without additional glaucoma surgical intervention. RESULTS: The mean IOP (37.8 ± 11.86 to 12.2 ± 2.8 mm Hg; p<0.0001) and mean number of AGM (3.4 ± 1.2 to 0.4 ± 0.1; p<0.001) were significantly reduced after surgery at 2 years. Kaplan-Meier survival analysis showed a cumulative probability of success for IOP control of 92% at 2 years of follow-up. CONCLUSIONS: Combined AGV and phacoemulsification is an effective treatment for controlling refractory UG with complicated cataract under infliximab.
