New approach in the treatment of ophthalmic neovascular disorders: using fusion protein aflibercept
The aim of this review is to appraise the usage of a newly approved anti-vascular endothelial growth factor (anti-VEGF) fusion protein, aflibercept, in ocular neovascular disorders such as diabetic retinopathy and age-related macular degeneration. Aflibercept is a soluble fusion protein, which combines ligand-binding elements taken from the extracellular domains of VEGF receptors 1 and 2 fused to the Fc portion of IgG. This protein contains all human amino acid sequences, which minimizes the risk for immunogenicity in human patients. In this short review we investigate the available literature and data from clinical studies on the efficacy, pharmaceutical and pharmacological properties of aflibercept, and identify its possible advantages over commercially available anti-VEGF drugs.Biomedical Reviews 2014; 25: 59-65
Optic disc melanocytoma associated with macular cyst
BACKGROUND: Optic disc melanocytoma (ODM) is a benign tumor, most often asymptomatic and stationary. However occasionally it can grow slowly, cause visual loss or extremely rarely undergoes into malignant melanoma. Here lies the importance of periodic ocular examination and reliable documentation.AIM: to report a rare case of growing ODM, associated with macular cyst with related visual loss, 25-years follow-up, and documentation by color photography, optical coherence tomography (OCT) and fluorescein angiography (FAG).METHODS: Full ophthalmic examination, fundus color photography, FAG and OCT.CASE REPORT: An asymptomatic 40-year-old Caucasian female with normal visual acuity at routine ocular examination had a pigmented elevated lesion on the left optic disc, occupying the inferotemporal half. The diagnosis of ODM was based on clinical assessment, FAG, fundus photographies, and observation was recommended. Ten years later she complained of gradually decreasing visual acuity in the left eye. Dilated ophthalmoscopy showed an evidence of slow growth of ODM and initial macular degeneration. After 25 years fundus color photography, FAG, and OCT documented mild progressive growth of ODM and macular cyst in the same eye.CONCLUSION: According to the literature, optic disc melanocytoma is generally recognized to be a stationary lesion with excellent prognosis and no treatment is usually necessary. In our case fundus color photography, FAG and OCT data reveal persisting ODM. Despite the progressive growth of ODM and moderate to significant visual loss, the malignant transformation is not proved. We suggest that loss of vision is related with macular lesion. To our knowledge we report a rare case of 25 years follow-up of growing ODM with visual loss, associated with macula degeneration/cyst.
