Intravitreal bevacizumab causes rapid regression of disc neovascularization associated with large optic disk melanocytoma: a case report.

Optic disk melanocytoma (ODM) is a rare ophthalmic tumor that can present with local compressive effects such as retinal vascular occlusion (RVO) that results in neovascularization of the disk (NVD) and is reportedly challenging to treat. We report the case of a 37-year-old Black African male with a two-year history of painless nonprogressive blur in his right eye vision. Findings on ocular examination include best corrected visual acuity right eye 6/18 and left eye 6/6, right eye relative afferent pupillary defect, and a large dark brown pigmented mass covering the optic disc measuring 4.

Patients' Acceptance of Glaucoma Therapy in Sub-Saharan Africa.

Prcis: Patients' acceptance of glaucoma therapy was high overall in this study, but lower for surgery than for laser or medical therapy. Fear and cost were the leading reasons why patients declined recommended therapy and they were treatment-specific. Cost was the primary reason for declining medical and laser therapy, while fear was the most common reason for declining surgical therapy.

Patients And Methods: A multicenter, prospective, cross-sectional study examining the fellow eye of consecutive patients who were diagnosed with different types of RD.

Low rates of optical coherence tomography utilization in the diagnosis and management of retinovascular diseases in a lower middle-income economy.

Background: Optical coherence tomography (OCT) is widely used as the standard of care in evaluating macular and retinovascular diseases. However, the degree of OCT utilization is yet to be researched in a resource-limited country where wide gaps exist in access to healthcare.

Aim: To determine the rate of utilization of the OCT in diagnosis, pre-treatment, and post-treatment evaluation of macular and retinovascular diseases treated with intravitreal anti-vascular endothelial growth factor injection (IVI).

Glaucoma Treatment Patterns in Sub-Saharan Africa.

Prcis: Physicians were most likely to recommend primary medical therapy upon diagnosis of glaucoma. Laser therapy was underutilized where they were available. Physicians were more likely to recommend surgery in severe glaucoma, laser therapy in mild glaucoma, while recommendation of medical therapy did not depend on glaucoma severity.

Outcome of peripapillary polypoidal choroidal vasculopathy treatment using combination therapy intravitreal ranibizumab and thermal retinal laser photocoagulation.

We present the case of a middle-aged female Nigerian diagnosed to have right eye peripapillary polypoidal choroidal vasculopathy (PCV). At presentation, her right eye Snellen visual acuity was 6/24+ (unaided) and 6/12 (aided) and the left eye was 6/9 (unaided) and 6/6 (aided).
