Surgical induced necrotizing scleritis following intraocular lens replacement

To report a surgical-induced necrotizing scleritis, as well as its medical and surgical management.

Case-report.

An 88 year-old patient with a three-day severe single-left-eye ocular pain. One-time surgery involving PPV with removal of dislocated intraocular lens and secondary implantation of iris-claw Artisan® lens was performed 6 months earlier. Visual acuity of 20/100. Slit-lamp examination revealed a 5 × 2 mm non-suppurative superior scleral defect. Empirical topical antibiotic treatment with dexamethasone, as well as oral doxycycline was started. Infectious and autoimmune diseases were ruled out. Non-infectious scleritis treatment was conducted with intravenous Methylprednisolone 3 day pulses, followed by weekly tapered Prednisone and intramuscular Methotrexate. However, 1 month after the diagnosis, the defect was worsened; hence, a heterologous scleral patch graft was performed and, days after the intervention, Adalimumab was initiated. To date, 6 months later, remains with proper scleral patch, a diary low-dose Prednisone, and spacing Adalimumab treatment.

Surgery-induced necrotizing scleritis is a severe condition that compromise the ocular and visual integrity. Proper diagnosis, as well as early treatment is required to achieve remission, prevent relapses, and avoid structural complications. In refractory cases, anti-TNF-α immunotherapy associated with surgical tectonic graft interventions can achieve promising results.
