Ocular complications of oak processionary caterpillar setae in the Netherlands; case series, literature overview, national survey and treatment advice.

During early summer 2019, the Netherlands experienced an outbreak of the exotic oak processionary caterpillar. The vast number of caterpillars, which live in large nests on oak trees before they turn into moths, possess thousands of small, barbed hairs (setae) that are disseminated with the wind. The hairs cause a range of primarily dermatologic problems. However, Dutch ophthalmologists started reporting patients with ophthalmologic complaints caused by the penetrating hairs of the oak processionary caterpillar. This paper focuses on the ophthalmologic complications caused by the caterpillar hairs. We collected a series of four cases with reports ranging from a corneal erosion with hairs lodged into the cornea, to a sterile endophthalmitis in which hairs were found in the vitreous. A literature review for similar cases was performed using the PubMed and Embase database. Together with the Dutch Ophthalmic Society (Nederlands Oogheelkundig Gezelschap, NOG), a national survey was issued to determine the scale of this new problem. This showed that oak processionary caterpillar related complaints are primarily limited to the south of the Netherlands. Suggested ophthalmic treatment guidelines are presented. With the next summer at the doorstep, and limited preventative measures against the caterpillar hairs, we expect a new wave of ophthalmologic complaints coming year as well.

Impact of Uveitis on Quality of Life in Adult Patients With Juvenile Idiopathic Arthritis.

OBJECTIVE: To establish the impact of uveitis on the quality of life (QoL) in adult patients with juvenile idiopathic arthritis (JIA). METHODS: Adult patients with a history of JIA, both with (n = 31) or without (n = 51) chronic anterior uveitis, were included. Their scores on 3 validated QoL questionnaires (National Eye Institute Visual Functioning Questionnaire [NEI VFQ-25], Medical Outcomes Study 36-Item Short Form health survey [SF-36], and EuroQol 5-domain questionnaire [EQ-5D]) were analyzed to find factors that could influence QoL. RESULTS: The median overall composite score (OCS) of the NEI VFQ-25 was significantly worse in the uveitis group compared to the non-uveitis group (respectively, 83.4 [range 15.2-94.7] and 94.9 [range 46.3-100]; P < 0.001). Nearly all subscale scores were lower in patients with uveitis than in patients without uveitis (P < 0.001 for all). After adjusting for duration of arthritis, JIA subtype, arthritis onset before or after 1990, and the use of systemic immunomodulatory medication, the QoL was still worse in patients with uveitis (NEI VFQ-25 OCS regression coefficient = -11.7; P = 0.002). No significant differences were found between the groups for the SF-36 and the EQ-5D. In the total JIA group, the use of systemic medication appeared to negatively influence some general QoL scores. CONCLUSION: Having a history of uveitis has a substantial negative effect on the vision-related QoL in JIA in adulthood, despite good visual acuity. General QoL scores did not differ between uveitis and non-uveitis patients, but the use of systemic immunomodulatory treatment, independent of uveitis, did negatively influence general QoL scores in adult JIA patients.
