Ocular dirofilariasis: Ophthalmic implication of climate change on vector-borne parasites

Purpose: To describe a geographically rare case of ophthalmic dirofilariasis. Observations: An 81-year-old male of good socioeconomic status living in the state of Michigan in the United States, presented to the eye clinic with a painful red left eye. He had not traveled outside of the state of Michigan in over three years. He was found to have a 7 cm long subconjunctival roundworm, which was ultimately extracted. Conclusions and importance: With increasing global temperatures, ocular dirofilariasis is being introduced in more northern climates and should be included in the differential diagnosis in areas previously isolated from these vector-borne parasites

Early Evolution of the Vitreomacular Interface and Clinical Efficacy After Ocriplasmin Injection for Symptomatic Vitreomacular Adhesion

BACKGROUND AND OBJECTIVE: To determine early evolution of the vitreomacular interface and clinical efficacy and safety profile after ocriplasmin treatment. PATIENTS AND METHODS: Retrospective, multicenter, observational case series. Patients with vitreomacular adhesion (VMA) confirmed on optical coherence tomography (OCT) received a single intravitreal ocriplasmin injection. Changes in the vitreomacular interface were evaluated by spectral-domain OCT. Adverse events were monitored at all visits. RESULTS: Of 22 patients treated with ocriplasmin, 14 (64%) had VMA resolution, with six (43%) achieving VMA release within the first week. Eight patients (36%) showed improvement in visual acuity (VA) of at least two Snellen lines. Rate of VMA resolution was 79% for VA less than 20/40 and 38% for VA of 20/40 or greater. Safety findings include changes in the ellipsoid layer (n = 3) and transient increases in subretinal fluid (n = 6). CONCLUSION: Ocriplasmin was effective for VMA resolution, with a rapid onset of action. Patients with worse baseline VA showed a higher VMA resolution rate.status: publishe
