Clinical findings
Blinking or spasms of the eyelids, dry eyes, photosensitivity.

Aetiology
Emotional stress, sleep deprivation or use of stimulants—e.g., amphetamines, caffeine, nicotine, decongestants.

Management
Botulinum toxin (Botox), surgery (protractor myomectory), dark glasses for photosensitivity.

blepharospasm

Uncontrollable winking or sustained tight closure of the eyes caused by involuntary contraction of the flat eyelid muscle under the skin. Blepharospasm may result from a sharp foreign body in the eye or a corneal ulcer, but also occurs as a psychologically induced TIC. Botulinum toxin has been found useful in this condition.

blepharospasm 

Tonic or chronic spasm of the orbicularis oculi muscle which involves involuntary closure of the eyelids. It is often provoked by a foreign body in the eye, an abrasion or inflammation of the cornea or conjunctiva, or by excessive exposure to ultraviolet light (e.g. actinic keratoconjunctivitis). Treatment consists chiefly of injection into the muscles around the eyelids of botulinum toxin. See botulinum toxin; chemodenervation; actinic keratoconjunctivitis; orbicularis muscle.

It has been shown that treating patients for 6 months with topical 0.05% cysteamine drops administered 5 times daily resulted in reduction of corneal cystine crystals, improvement in visual acuity, and decreased photophobia and blepharospasm. However, there was no decrease in corneal crystals after topical cysteamine use in our patient.

Primary congenital glaucoma (PCG) is the most common type of glaucoma in children, accounting for 2.5–15% of all documented cases of pediatric blindness.[sup][1],[2] The prevalence of PCG is variable in different populations and occurs in approximately 1 in 10,000 births.[sup][2] The classic symptoms of PCG include epiphora, photophobia, and blepharospasm. Oftentimes, the condition will lead to increased intraocular pressure (IOP), opaque cornea, enlarged eyeball, damaged optic disc, and loss of visual function.
