Repeated intravitreal injections of antivascular endothelial growth factors and risk of intraocular pressure medication use.

PURPOSE: To determine the risk of initiating ocular hypertension and glaucoma treatment with repeated injections of antivascular endothelial growth factors (anti-VEGF). METHODS: A unique, retrospective cohort study was performed using a large national US medical claim database. The study population included patients who had 1 or more injections of an anti-VEGF agent. Exclusion occurred for any previous glaucoma, glaucoma suspect, glaucoma-related procedure, an ocular steroid injection, or not seeing an eye care provider at least once in each year of follow-up. Cohorts were divided into quartiles based on the number of injections performed over the follow-up period. Patients were observed for 2 and 3 years. The main outcome measure was defined as any new prescription for an ocular antihypertensive medication with a concurrent diagnosis of glaucoma, glaucoma suspect, or ocular hypertension. Multivariate logistic regression determined the odds of initiating glaucoma treatment in each injection quartile while controlling for numerous covariates. Sensitivity analysis assessed outcomes that included new medication only as well as a new medication plus diagnosis of glaucoma. RESULTS: In total, 17,113 and 9992 patients met 2- and 3-year observation end points, respectively. The multivariate odds ratio for initiating glaucoma treatment at 2 years was higher in the highest quartile (OR 1.96, 95% CI 1.39-2.76, p < 0.001) compared with the lowest. The 3-year comparison had similar results with increased odds in the highest quartile (OR 1.51, 95% CI 1.07-2.13, p = 0.006) compared with the lowest. Sensitivity analyses also showed similar results with more injections being associated with initiating treatment (p < 0.053 for all comparisons). CONCLUSIONS: Repeated anti-VEGF injections are associated with an increased odds of initiating treatment for ocular hypertension and glaucoma.

Ocular Dipping in a Patient With Hemiplegic Migraine.

A 5-year-old girl presented with acute, rapidly progressive encephalopathy following minor head trauma and was found to have ocular dipping. Her encephalopathy was secondary to a channelopathy caused by a CACNA1A mutation. This is the first reported case of ocular dipping in an encephalopathic child with CACNA1A-confirmed hemiplegic migraine. [J Pediatr Ophthalmol Strabismus. 2018;55:e4-e6.].

Management of Presumed Endogenous Fungal Endophthalmitis in a Child With Acute Lymphoblastic Leukemia.

The authors describe a case of presumed endogenous fungal endophthalmitis in an immunocompetent pediatric patient with acute lymphoblastic leukemia. A 15-year-old boy with a history of high-risk B-cell acute lymphoblastic leukemia status post-chemotherapy presented with acute changes in vision in his left eye. Fundus examination revealed a white bi-lobed chorioretinal lesion with overlying vitritis and associated subretinal fluid. Magnetic resonance imaging of the brain revealed small ring-enhancing lesions in the right parietal and left occipital lobes. Blood, cerebrospinal fluid, aqueous, and vitreous cultures were all negative. Bone marrow and vitreous cytology were negative for malignant cells. The patient was treated for presumed fungal endophthalmitis with systemic and intravitreal voriconazole, followed by pars plana vitrectomy with intravitreal voriconazole and amphotericin B injections. The chorioretinal lesion resolved and visual acuity recovered to 20/20. Chorioretinal infiltrates in a patient with leukemia may require treatment even in the absence of a definitive diagnostic test result. Intervention should be guided by risk analysis and clinical judgment. [J Pediatr Ophthalmol Strabismus. 2017;54:e42-e46.].
