Corticosteroids are valuable medicines, but they can raise eye pressure and speed up cataracts. The right reason, duration and monitoring keep them safe.

When straight lines look bent in one eye, a thin film on the macula may be the cause. OCT shows the membrane clearly, and not every case needs surgery.

Shimmering zigzags and flashing lights are often migraine aura, but not always. How it started, how long it lasted and which eye was affected all matter.

Burning, gritty and watering eyes can start at the eyelid margins. Blepharitis affects the oil glands that keep tears stable, and consistent lid care helps.

High blood pressure can quietly change the blood vessels in the retina. An eye examination can reveal these effects, often before you notice any symptoms.

A vision chart shows how well you see, not why. An OCT scan images the layers of the retina and optic nerve, helping detect and track change over time.

A red eye is common, but redness is not a diagnosis. Pain, reduced vision and light sensitivity change its meaning, and some causes need prompt specialist care.

Keratoconus is a condition where the cornea becomes thinner and progressively cone-shaped, causing blurred vision, increasing astigmatism, and a constantly changing glasses prescription. Early detection through corneal measurements and appropriate treatment can help preserve vision and slow progression.
