People with nystagmus have difficulty in focusing their eyes on an object or person. Their eyes always look involuntarily from side to side, up and down or sometimes jerk. Nystagmus is estimated to affect one out of several thousand children, usually from an early age.

There are many types of nystagmuses. Congenital nystagmus is born. The eyes of children who suffer from this type of nystagmus may move together or uncoordinatedly. Manifest nystagmus is present at all times while latent nystagmus occurs only when one eye is covered. Manifest-latent nystagmus is continually present, but worsens when one eye is covered. Acquired nystagmus can be caused by diseases, accidents or neurological problems. Other potential factors include hyperventilation, nicotine and even vibrations.

Most types of nystagmuses are born or develop in children’s early lives. People with nystagmus can not control their eyes and their vision and self-concept will be affected. Sweeping eyes are impossible to acquire clear images so that many nystagmus patients have severe vision problems. Nystagmus patients just see objects in a way that is profoundly different from other normal individuals so that their appearances are affected. It is also important for nystagmus patients to deal with personal and social consequences, since their relation with other people, educational and work opportunities can also under influence.

Except for disease reasons, most nystagmuses are caused by neurological problems. Optokinetic nystagmus and vestibular nystagmus are basic types of nystagmus. Vestibular nystagmus is always associated with inner eye problems. People with vestibular nystagmus have jerking eyes and may suffer from nausea and vertigo. Decongestant is a possible treatment.

Regular eye exams are critical for nystagmus patients, in order to get visual and health monitoring. For light nystagmuses, eyeglasses and contact lenses can provide better vision, while the latter type is more competent. Surgical treatments can reduce null positions, lessen head tilt and improve cosmetic appearance, while drugs such as Botox reduce some nystagmic movements.

Both anterior blepharitis and posterior blepharitis are forms of eyelid inflammation, particularly at the lid margins. These two types of blepharitis bring symptoms such as eye irritation, burning, tearing crusty debris, dryness and red eyelid margins. There are still more severe consequences: eyelash loss, ectropion, dilated and visible capillaries and potential cornea erosion.

However, the two types affect different areas of eyelid and have different reasons. While the outside front of the eyelid is associated with anterior blepharitis, posterior blepharitis affects the inner eyelid. While anterior blepharitis is always caused by scalp dandruff and bacteria, posterior blepharitis results from skin disorders.

Blepharitis is likely to recur and tends to be chronic, so that its treatment requires more patience and skills. The most common treatments include compress applying, cleansing, eyelids massaging etc… Before cleansing your eyelids, you can use warm compress to loosen and warm up the eyes’ crusts. This process always takes five minutes every time and four times daily. You can just dampen a clean washcloth with warm water and put it on your closed eyes. After warming up your eyes with compress, you should cleanse eyelids with cool washcloth and cotton swab several times each day.

There are other treatments: antibiotic treatment for special blepharitis, eyelid massaging for gland dysfunction and flaxseed oil supplements for meibomian seborrheic blepharitis.

If dryness is aroused by blepharitis, eye drops, artificial tears, lubricating ointments, silicone punctual plugs, and steroids can offer effective help under your doctor’s instruction.

Blepharitis also affects your contact lenses selection. Under particular circumstances, you will be suggested to stop wearing contacts for a certain period. Even if you are allowed to wear contacts, you’d better to choose RGPs, because of they are more resistant to deposits.

Makeup can never be applied to blepharitis eyelids, while sometime anti-dandruff shampoo is needed for scalp and eyebrows.
