Cataract management in juvenile idiopathic arthritis: simultaneous versus secondary intraocular lens implantation

Long-term visual acuity outcomes following cataract surgery in eyes with ocular inflammatory disease

PURPOSE

To evaluate the long-term visual acuity (VA) outcome of cataract surgery in inflammatory eye disease.

SETTING

Tertiary care academic centres.

DESIGN

Multicentre retrospective cohort study.

METHODS

A total of 1741 patients with non-infectious inflammatory eye disease (2382 eyes) who underwent cataract surgery while under tertiary uveitis management were included. Standardised chart review was used to gather clinical data. Multivariable logistic regression models with adjustment for intereye correlations were performed to evaluate the prognostic factors for VA outcomes. Main outcome measure was VA after cataract surgery.

RESULTS

Uveitic eyes independent of anatomical location showed improved VA from baseline (mean 20/200) to within 3 months (mean 20/63) of cataract surgery and maintained through at least 5 years of follow-up (mean 20/63). Eyes that achieved 20/40 or better VA at 1 year were more likely to have scleritis (OR=1.34, p<0.0001) or anterior uveitis (OR=2.2, p<0.0001), VA 20/50 to 20/80 (OR 4.76 as compared with worse than 20/200, p<0.0001) preoperatively, inactive uveitis (OR=1.49, p=0.03), have undergone phacoemulsification (OR=1.45 as compared with extracapsular cataract extraction, p=0.04) or have had intraocular lens placement (OR=2.13, p=0.01). Adults had better VA immediately after surgery, with only 39% (57/146) paediatric eyes at 20/40 or better at 1 year.

CONCLUSIONS

Our results suggest that adult and paediatric eyes with uveitis typically have improved VA following cataract surgery and remain stable thereafter for at least 5 years.

Uveitis Associated with Juvenile Idiopathic Arthritis

Juvenile idiopathic arthritis (JIA) is the most common cause of uveitis in children. While symptoms are usually mild, persistent eye inflammation could lead to severe complications and impaired vision. It is essential that JIA patients at risk are diagnosed with uveitis early, receive adequate treatment, and avoid developing complications, such as cataract, glaucoma, and amblyopia. The purpose of this mini-review is to summarize the screening strategies and clinical management for JIA-associated uveitis (JIA-U) as well as the current state of molecular markers linked to this condition. Because glaucoma is one of the most common causes of visual loss in JIA-U, special focus will be put on this serious complication. We conclude by describing the current evidence regarding the long-standing question of whether chronic anterior uveitis without arthritis may be the same disease entity as JIA-U.

Outcomes of cataract surgery in children who present with cataract at uveitis diagnosis

PURPOSE

To describe the clinical and demographic characteristics of patients presenting with cataract at uveitis diagnosis treated at a single institution between 2005 and 2019 and to analyze postoperative outcomes following cataract surgery.

METHODS

We retrospectively reviewed the medical records of children (<18 years of age) diagnosed with cataract at their initial uveitis presentation who subsequently underwent cataract extraction. Outcome measures were best-corrected visual acuity, number of uveitis flare-ups (cells ≥1+), and postoperative complications.

RESULTS

A total of 14 children (17 eyes) were included. Mean patient age was 7.2 ± 3.9 years. Methotrexate was initiated preoperatively in 11 patients; adalimumab, in 3. Primary intraocular lens was implanted in 4 eyes. Best-corrected visual acuity improved from a mean of 0.90 ± 0.40 logMAR preoperatively to 0.50 ± 0.35 logMAR at 1 year and 0.57 ± 0.40 logMAR at mean of 6.3 ± 3.4 years postoperatively. Four eyes (24%) had a single episode of uveitis flare-up during the first postoperative year. Macular and/or disk edema was discovered in 6 eyes following cataract removal. Only 3 eyes (18%) had ocular hypertension in the first year, but glaucoma developed in subsequent years in 7 eyes (41%), 5 of which required surgery.

CONCLUSIONS

In our study cohort, surgery for preexisting cataract at uveitis diagnosis resulted in improved visual acuity. Postoperative uveitis flare-ups were relatively uncommon, occurring in 4 of 17 eyes. Glaucoma was the main long-term complication.

Long-term effects of early/late-onset visual deprivation on macular and retinal nerve fibers layer structure: A pilot study

BACKGROUND/AIMS

Tomographic analysis of macular and peripapillary retinal nerve fibers layer (RNFL) thickness in patients with history of congenital (CC) and developmental cataract (DC).

METHODS

Analysis of macular and RNFL thickness using a spectral-domain optical coherence tomography was performed. Retinal layers thickness was measured using the internal segmentation software. Measurements of affected (unilateral and bilateral), contralateral eyes and control eyes were compared.

RESULTS

Patients with history of CC or DC (n = 13 and 11 respectively) and 35 healthy control subjects were enrolled. Thicker inner and outer nuclear layers (INL, ONL) and thicker ONL were found when CC and DC group when compared to controls respectively. Bilateral CC showed the most relevant differences. Slight thickening of CC inner retinal layers were found when compared to DC. Increased superonasal RNFL thickness was found in CC group when compared to DC and controls. Thickening of RNFL of contralateral unaffected eyes of unilateral CC were found when compared to controls.

CONCLUSION

Significant macular and RNFL thickness changes between CC, DC patients and controls that partially involve also contralateral unaffected eyes of unilateral congenital cataract were found. CC and DC groups show significant differences only in inner retinal layers thickness. Our data suggest that early visual deprivation may influence retinal arrangements occurring during development involving predominantly the outer nuclear layer and para/perifoveal inner retinal layers, and confirm that early treatment of CC allow to achieve better long-term visual outcome. Moreover functional and structural data support the hypothesis that unilateral amblyopia is not exclusively an unilateral issue.

Cataract Surgery with Intraocular Lens Implantation in Juvenile Idiopathic Arthritis-Associated Uveitis: Outcomes in the Era of Biological Therapy

This study compared the outcomes of cataract surgery with intraocular lens (IOL) implantation in patients with juvenile idiopathic arthritis (JIA)-associated chronic anterior uveitis treated with antimetabolite drugs and systemic corticosteroids (Non-Biological Group) versus patients treated with antimetabolites and biological drugs (Biological Group). A cohort of patients with cataract in JIA-associated uveitis undergoing phacoemulsification with IOL implantation was retrospectively evaluated. The main outcome was a change in corrected distance visual acuity (CDVA) in the two groups. Ocular and systemic complications were also recorded. The data were collected preoperatively and at 1, 12, and 48 months after surgery. Thirty-two eyes of 24 children were included: 10 eyes in the Non-Biological Group and 22 eyes in the Biological Group. The mean CDVA improved from 1.19 ± 0.72 logMAR preoperatively to 0.98 ± 0.97 logMAR at 48 months (p = 0.45) in the Non-Biological Group and from 1.55 ± 0.91 logMAR preoperatively to 0.57 ± 0.83 logMAR at 48 months (p = 0.001) in the Biological Group. The postoperative complications, including synechiae, cyclitic membrane, IOL explantation, glaucoma, and macular edema, were not statistically different between the two groups. An immunosuppressive treatment with biological drugs can improve the visual outcome after cataract surgery in patients with JIA-associated uveitis, but it does not significantly reduce postoperative ocular complications.

Monitoring and Treatment of Juvenile Idiopathic Arthritis-associated Uveitis: Brazilian Evidence-based Practice Guidelines

Purpose: To present a national guideline for ophthalmologic care and surveillance of juvenile idiopathic arthritis-associated uveitis (JIA-uveitis).Methods: Review article based on medical literature and the experience of an Expert Committee composed of members of the Brazilian Society of Pediatric Ophthalmology/Brazilian Council of Ophthalmology and the Brazilian Society of Pediatrics/Brazilian Society of Rheumatology. Studies with a high level of evidence were selected by searching the PubMed/Medline database. The final document was approved by the experts.Results: The main recommendations are that children/adolescents with JIA should undergo screening according to their risk factors. Ophthalmological checkups should also consider ocular inflammation and therapy. Topical glucocorticoids should be the first line of therapy, with systemic glucocorticoids acting as bridge treatments in severe uveitis. Methotrexate should be the first-line systemic therapy and anti-tumor necrosis factor (anti-TNF alpha) the second for uncontrolled uveitis.Conclusions: This evidence-based guideline for JIA-uveitis will be useful for both ophthalmology and rheumatology practice.

A Cross-Sectional Online Survey Identifies Subspecialty Differences in the Management of Pediatric Cataracts Associated with Uveitis

Introduction

To determine if differences exist between pediatric ophthalmologists and uveitis ophthalmologists in the treatment of pediatric uveitic cataracts and placement of intraocular lenses.

Methods

Uveitis ophthalmologists and pediatric ophthalmologists were surveyed via an online poll regarding their therapeutic management of pediatric uveitic cataract and intraocular lens (IOL) placement.

Results

Sixty-two responses from uveitis ophthalmologists and 47 responses from pediatric ophthalmologists were recorded. According to 79% of all responses, uveitis was not a contraindication for primary IOL implantation in patients with controlled intraocular inflammation. Pediatric ophthalmologists were more likely to respond that the presence of chronic juvenile idiopathic arthritis-associated iridocyclitis, pars planitis, or recurrent acute anterior uveitis is a contraindication for primary IOL implantation in pediatric cases with full control of intraocular inflammation. There was no consensus within either specialty with regard to the preferred IOL material for lens implantation. Uveitis ophthalmologists were more likely to report the use of intravenous and intravitreal steroids for perioperative treatment. In cataract surgery for a child with recurrent acute anterior uveitis, a higher percentage of uveitis ophthalmologists (71%) than pediatric ophthalmologists (50%) responded that the posterior capsule should be primarily opened. A higher percentage of uveitis ophthalmologists also stated that anterior vitrectomy should be performed at the time of cataract surgery in all three uveitis types.

Conclusions

Pediatric ophthalmologists and uveitis ophthalmologists have similar approaches to the management of pediatric uveitic cataract removal and IOL insertion, but several differences remain between these subspecialties. Continued collaboration between the subspecialties would be helpful to better develop consistent criteria to improve patient care.

[Cataract surgery in children with non-infectious uveitis: Review of current practices in France]

PURPOSE

To evaluate the medical-surgical management of cataract surgery in children with chronic uveitis in various French pediatric ophthalmology centers.

MATERIALS AND METHODS

Two-part study: first, a descriptive observational segment on the evaluation of French practices. A questionnaire was sent to the various pediatric ophthalmologists in France. A second retrospective chart review, including children with non-infectious chronic uveitis who had cataract surgery in the pediatric ophthalmology department of Bordeaux University Hospital from 2008 to 2017.

RESULTS

Twenty-one ophthalmologists responded to the questionnaire. Only 23.8% systematically initiated immunosuppressive drugs (aside from corticosteroids) before surgery. A total of 88.2% prescribed oral corticosteroid treatment preoperatively. Eleven surgeons administered intravenous corticosteroid boluses during the surgery, and primary lens implantation is the most common method used in 95.2%. A total of 76.2% initiated oral steroid therapy after surgery. Postoperatively, all surgeons started local therapy with high-dose corticosteroids. At one year, 100% achieved improvement of visual acuity greater than or equal to 2 lines. On our service, 10 eyes (7 children) underwent cataract surgery. Seven were treated with systemic immunosuppressive drugs (aside from corticosteroids) and 80% of cases received oral corticosteroid therapy a few days before surgery. An intravenous corticosteroid bolus was administered preoperatively in 8 cases, and primary lens implantation was performed in 100% of cases. Postoperatively, 5 children received oral corticosteroid treatment. All were treated with local high dose steroids. At one year, the mean best-corrected visual acuity was 0.18 LogMar (0-0.7, SD: 0.25).

CONCLUSION

When performed with an aggressive anti-inflammatory protocol, cataract surgery leads to a good visual outcome in selected children with chronic uveitis.

Safety and efficacy of dexamethasone implant along with phacoemulsification and intraocular lens implantation in children with juvenile idiopathic arthritis associated uveitis

PURPOSE

To assess the safety and efficacy of intraoperative intravitreal dexamethasone implant in patients of juvenile idiopathic arthritis (JIA)-associated uveitis undergoing phacoemulsification with posterior chamber intraocular lens (PCIOL) implantation.

METHODS

Retrospectively, data of patients with JIA-associated uveitis undergoing phacoemulsification with PCIOL implantation with intraoperative dexamethasone implant injection were analyzed. Patients with a minimum follow-up of 6 months were included. Primary outcome measures were ocular inflammation, intraocular pressure (IOP), best-corrected visual acuity (BCVA), and worsening of uveitis.

RESULTS

8 eyes of 6 patients were included. BCVA was significantly improved at 1, 3, and 6 months postoperatively 0.20 ± 0.09, P = 0.008; 0.18 ± 0.11, P = 0.008; and 0.24 ± 0.11, P = 0.01, respectively. No statistical difference noted in mean IOP at various follow-up visits. None developed worsening of uveitis or Cystoid macular edema.

CONCLUSION

Intraoperative intravitreal dexamethasone implant is a safe and effective in preventing and managing the postoperative inflammation in children with JIA-associated uveitic cataract.

Cataract Surgery with Primary Lens Implantation in Children with Chronic Uveitis

PURPOSE

To evaluate the evolution of chronic uveitis in children undergoing cataract surgery with primary intraocular lens (IOL) implantation.

METHODS

Twelve children with chronic uveitis underwent cataract surgery with primary posterior chamber intraocular lens (IOL) implantation.

RESULTS

Fourteen eyes were implanted with a foldable hydrophobic acrylic IOL. The mean follow-up was 35.39 months (8.72-69.57). The mean BCDVA before surgery and at the end of follow-up was 1.11 (0.40-2.30; SD: 0.57) and 0.48 (0-3; SD: 0.77; p=0.007) respectively. The mean oral corticosteroids dosage after surgery and at the end of follow-up was 0.80 mg/kg/day (SD: 0.37) and 0.17 mg/kg/day (SD: 0.24; p=0.001) respectively. All patients except one were treated with methotrexate. Four patients (5 eyes) were additionally treated with anti-tumor necrosis factor agent.

CONCLUSIONS

Cataract surgery with primary posterior chamber hydrophobic IOL implantation is possible and leads to a good visual recovery in cases of pediatric chronic uveitis. This surgery requires aggressive anti-inflammatory management with immunosuppressive drugs to control inflammation and reduce the corticosteroids dosage.

Controversies in intraocular lens implantation in pediatric uveitis

Cataract is one of the most common and visually debilitating complications of pediatric uveitis. It develops as a consequence of chronic inflammation and steroid use and is seen most often in juvenile idiopathic arthritis (JIA)-associated uveitis. Cataract extraction with intraocular lens (IOL) insertion has been carried out with a measure of success in non-uveitic pediatric eyes, but in cases of uveitis, multiple factors affect the final outcome. Chronic inflammation and its sequelae such as band keratopathy, posterior synechiae, and cyclitic membranes make surgical intervention more challenging and outcome less certain. Postoperative complications like increased inflammation, glaucoma, posterior capsular opacification, retrolental membranes, and hypotony may compromise the visual outcome. Early refractive correction is imperative in pediatric eyes to prevent amblyopia. The use of contact lenses and intraocular lenses in pediatric uveitic eyes were fraught with complications in the past. Surgical interventions such as vitreo-lensectomy followed by contact lens fitting and small incision cataract surgery followed by different types of intraocular lenses have been utilized, and many reports have been published, albeit in small patient groups. This review analyzes and discusses the existing literature on intraocular lens implantation in cases of pediatric uveitic cataract surgery.

Chronic Non-infectious Uveitis in Patients with Juvenile Idiopathic Arthritis

PURPOSE

To describe clinical findings and analyze treatment evolution of chronic, non-infectious uveitis in patients with juvenile idiopathic arthritis (JIA).

METHODS

A total of 82 patients (147 eyes) with JIA-related uveitis treated for ≥2 months were included (78% females; 79% bilateral uveitis; 74% anterior uveitis). Outcome measures were visual acuity (VA), inflammation control, side-effects, and surgical procedures.

RESULTS

Mean ± SD age at diagnosis was 4.9 ± 3.8 years; mean ± SD follow-up time was 8.7 ± 7.8 years. Mean VA did not significantly change throughout the study. Three (2%) eyes resulted in no light perception (NLP) vision. Thirty (37%) patients underwent 69 procedures. In total, 41 (50%) patients achieved inflammation control. TNF-α inhibitors were significantly associated with inflammation control. Seven (8.5%) patients stopped treatment due to side-effects.

CONCLUSIONS

JIA is a cause of significant ocular morbidity. TNF-α inhibitor use was associated with inflammation control. Prospective, randomized, double blind clinical trials in this regard are warranted.
