Skuteczność ranibizumabu w idiopatycznej neowaskularyzacji naczyniówkowej – opis serii przypadków

Abstract

Objective: To evaluate the efficacy of the ranibizumab intravitreal injection in idiopathic choroidal neovascularization. Material and methods: The study included 3 patients (4 eyes), aged 17, 37 and 46, with visual acuity deterioration, warping and distortion of the central image lasting for 2–5 weeks. Inflammatory background of the disease was excluded. The baseline examination and follow-up included the best corrected visual acuity (BCVA), fluorescein angiography and central retinal thickness (CRT) analysis using optical coherence tomography (OCT). When ICNV was diagnosed, intravitreal injections of ranibizumab were administered. Results: During the first follow-up test, 3 eyes showed improvement of BCVA, and in the fourth eye BCVA remained unchanged. In funduscopy, all patients showed reduced haemorrhage and oedema of the central retina. The OCT showed a reduction of the CRT and improvement in the morphology of the macula. The observation period ranged from 4 to 55 months, and the number of repeated injections during the observation ranged from 2 to 5. Conclusions: Injections of ranibizumab into the vitreous brought a significant improvement in the function of the treated eye, and in the morphology of the retina in OCT.
