Association of Pediatric Atopic Dermatitis and Cataract Development and Surgery

Increased risk of cataract surgery in patients with allergic disease: a population based cohort study

We investigated the association between cataract and allergic diseases, including atopic dermatitis (AD), allergic rhinitis (AR), and asthma using 2,631,015 subjects' data from the 2009 National Health Insurance Service-Health Screening Cohort in Korea. Each allergic disease was defined as three or more occasions of diagnosis within 1 year with dedicated ICD-10 codes. The primary endpoint was newly received cataract surgery during the follow-up period. In total, 447,883 subjects had at least one allergic disease. During the mean follow-up of 7.8 ± 1.7 years, newly developed cataract surgery was observed in 301,693 subjects (allergic group, n = 69,321; non-allergic group, n = 232,372). After adjusting for demographic characteristics (age, sex), systemic and ocular comorbidities, socioeconomic status, and lifestyle factors (smoking, drinking, regular exercise), the allergic group had a higher hazard ratio (HR) for cataract development compared with the non-allergic group. We further performed a subgroup analysis for patients regarding sex and age. In the subgroup analysis of subjects with AD, men aged < 50 years had a higher HR compared to women of the same age group. In conclusion, subjects with allergic diseases had a higher risk of cataract surgery than their counterparts, and the combination of AD and AR resulted in the highest risk. Particularly, the association was more evident in male than female patients with AD aged < 50 years.

Atopic Dermatitis-Beyond the Skin

Atopic dermatitis is a chronic inflammatory disease that can arise during the first months of life or at maturity and have a significant negative impact on the quality of life. The main pathogenic mechanism is the breakdown of cutaneous barrier integrity, which is associated with systemic inflammatory immunologic disorders. Atopic dermatitis involves numerous immunologic, allergic, respiratory, and ophthalmologic comorbidities that develop through similar intricate pathogenic phenomena. The atopic march represents the evolution in time of various allergic diseases, of which food allergies often cause the first manifestations of atopy, even from a very young age. Chronic inflammation translated through specific markers, next to increased immunoglobulin E (IgE) serum levels and heterogenous clinical manifestations, argue for the inclusion of atopic dermatitis in the systemic disease category.

Anterior lenticular opacities in Costello Syndrome

Purpose

A case of anterior lenticular opacities in a patient of Costello Syndrome is reported.

Observations

Bilateral anterior capsular plaque along with anterior lens opacities (Anterior Segment Optical Coherence Tomography) has been demonstrated in a patient of Costello Syndrome presenting with atopic dermatitis.

Conclusions

All patients with Costello Syndrome require a detailed anterior segment examination and a close follow up, as even minute lenticular opacities cause visual impairment leading to amblyopia and may require an early surgical intervention.

Risk Factors for Intraocular Lens Dislocation After Phacoemulsification: A Nationwide Population-Based Cohort Study

PURPOSE

Few studies have measured the incidence and risk factors of intraocular lens (IOL) dislocation in the total population. We investigate the risk factors for IOL dislocation in a nationwide Korean cohort.

DESIGN

Retrospective cohort study.

METHODS

National data on 2,162,191 subjects who underwent cataract surgery were collected from the Health Insurance Review and Assessment service database of health claims from 2009 to 2016. The Health Insurance Review and Assessment database was used to identify potential risk factors for IOL dislocation, including age, sex, and various pre- and postoperative ophthalmic conditions. The hazard ratios (HRs) and confidence intervals (CIs) of these risk factors were assessed with a multivariable-adjusted Cox regression model.

RESULTS

IOL dislocation occurred in 15,170 patients (0.7%) in the cataract surgery cohort (2,162,191 patients). The incidence rate of IOL dislocation peaked at 40-50 years of age, although the mean age of IOL dislocation was 65.25 ± 10.81 years. The average male:female ratio was 1.8. The adjusted HR for IOL dislocation in patients with partial vitrectomy was 11.93 (95% CI 10.95-12.99; P < .0001). Posterior capsulotomy performed within 1 year after the cataract surgery significantly decreased IOL dislocation, with an adjusted HR of 0.48 (95% CI 0.44-0.51; P < .0001).

CONCLUSIONS

IOL dislocation tended to occur in young males. Anterior vitrectomy was a significant risk factor for IOL dislocation, while posterior capsulotomy after surgery was associated with a decreased risk of IOL dislocation.

The Association with rhegmatogenous retinal detachment and paediatric atopic dermatitis: a 12-year Nationwide Cohort Study

PURPOSE

Historically, atopic dermatitis (AD) is associated with an increased risk of rhegmatogenous retinal detachment (RRD). However, uncertainty remained regarding the effect of AD itself and comorbidities (e.g., allergic diseases, cataract surgery) on RRD occurrence in a large, population-based paediatric population.

PATIENTS AND METHODS

We analysed the 12-year National Health Insurance Service database (2002-2013) covering the entire Korean population to estimate the association between AD and RRD in people aged under 20 years.

RESULTS

We identified 3142 RRD patients, and matched 18,852 controls (six controls to each RRD patient); therefore, we included 21,994 peoples under aged 20 years in the analyses. AD was more prevalent in the RRD group (329 patients, 10.47%) than the control group (1043 patients, 5.53%; P < 0.001), and so were severe AD (153 patients [4.87%] and 223 patients [1.18%], respectively; P < 0.001). In conditional logistic regression analysis, AD was associated with RRD (OR, 1.61; 95% CI, 1.93-1.87) even after adjusting for allergic conditions, connective tissue disease, uveitis, and cataract surgery. In addition, severity of AD was associated with an increased risk of RRD (OR for non-severe AD and severe AD, 1.26 [95% CI, 1.05-1.51] and 2.88 [95% CI, 2.25-3.68]).

CONCLUSION

This study suggests that AD itself is a risk factor of RRD in children by showing the association between AD and RRD occurrence and the biologic gradient even after adjustment for known confounders including allergic conditions, uveitis, and cataract surgery.

Ocular Co-Morbidities of Atopic Dermatitis. Part II: Ocular Disease Secondary to Treatments

Treatments used for managing atopic dermatitis (AD) may have adverse ocular effects that permanently affect vision. The objective of this review is to raise awareness among dermatologists regarding the potential ocular adverse effects of various AD therapies, including corticosteroids, calcineurin inhibitors, an interleukin-4 receptor α (IL-4Rα) antagonist, and phototherapy. Pertinent potential short- and long-term risks of these therapies include elevations in intraocular pressure from use of topical corticosteroids and conjunctivitis from use of dupilumab. Since some of these adverse effects may not exhibit symptomatology until permanent vision impairment occurs, it is important for dermatologists to understand these risks and proactively ensure their patients are receiving appropriate measures to prevent them.

Ocular Co-Morbidities of Atopic Dermatitis. Part I: Associated Ocular Diseases

Ocular diseases associated with atopic dermatitis (AD) may be sight-threatening. A general understanding of the pathophysiology, diagnosis, and treatment of atopic eye disease may assist dermatologists in knowing when to refer to ophthalmology and in co-managing these diseases with ophthalmologists. Ocular diseases associated with AD include eyelid dermatitis, keratoconjunctivitis, keratoconus, cataract, and retinal detachment. AD patients are also at higher risk for bacterial and viral ocular infections. The objective of this article is to provide a current review of ocular diseases that commonly affect AD patients. The pathogenesis, clinical manifestations, diagnosis, and treatment of ocular co-morbidities of AD will be discussed.
