Introduction Medications can cause ocular adverse effects. Most disappear once the drug is discontinued (such as blurry vision from an anticholinergic). In other cases, the damage can be permanent (such as vision loss with a PDE-5 inhibitor).

Introduction Eye floaters are tiny specks, dots, circles, lines or cobwebs that can be seen in your field of vision , especially when looking at a light-coloured area (e.g. blue sky or white wall). They are created when tiny clumps form in the clear, jelly-like substance (vitreous humour) inside the eye. As eye floaters are suspended in this "jelly", so they move when your eyeball moves. Eye floaters are very common and, for many people, are a part of natural aging process. Management In most cases, floaters are normal and harmless , hence typically don't require treatment. The floaters usually resolve with time, settle down outside the visual axis, and/or become less noticeable. However, a sudden increase in their number (particularly if they occur as flashing lights, or a new big floater) or visual deficit (e.g. vision loss) requires immediate professional attention.
