They postulated that headaches observed are due to associated contraction of the scalp muscles.6 Medical term for headache associated with eye strain or fatigue is asthenopia, which is thought to be triggered by ametropia, extra ocular muscle imbalance, improper reading or working environment and inaccurate reading or working habits.7 Another meta-analysis on the subject including 2465 subjects revealed that majority of children with asthenopia had no refractive error and estimated a pooled prevalence of ametropia of 19.7% in children.8 Ophthalmologists are frequently referred cases for evaluation of refractive errors and diagnose ocular causes of headache.
There was no more likely alternative explanation for the histopathological findings, such as a biopsy obtained from a myotendinous insertion site, ocular muscle biopsy, and rod core myopathy, among others.
[1] Structures that might be involved in this process include eyeball, fat, extra ocular muscle, lacrimal gland, connective tissues, and optic nerve.
Moreover, the authors say, "An imbalance in the ocular muscles tone can cause a movement dysfunction at the sphenoid bone, at the maxilla and at the ocular muscle nerves." In addition to muscle contraction, flexibility between the bones in the eye orbit and skull - particularly the phenopetrosal suture, the occipitomastoid suture, and the lacrimal bone--are key for functional drainage in the head and preventing IOP.

Furthermore, the reason why thyroid gland, orbital tissue including fibroblasts, and ocular muscle cells and sometimes skin are the selected targets of autoimmunity in Graves' ophthalmopathy or dermopathy has not been addressed [1].

While MG affects individuals of all racial groups, patients of African genetic ancestry, particularly juveniles, are more likely to develop an ocular muscle complication of MG compared to their European counterparts (Heckmann 2012).
(4) The occurrence of different leprosy-related eye complications in LL hansen's and Type II lepra reaction is about 44%, which includes ocular muscle weakness, lagophthalmos, ectropion, trichiasis, entropion, blocked nasolacrimal ducts, pterygium, impaired corneal sensation, corneal opacity, corneal nerve beading, punctate keratitis, iris atrophy, blindness, episcleritis, scleritis, iridocyclitis, iris atrophy and decreased visual acuity, corneal ulcer and cataract.
Ocular complications include uveitis, keratitis, conjunctivitis, conjunctival edema (chemosis), ocular muscle palsies, scleritis, retinal vascular occlusion and ulceration, scarring and even necrosis of the lids.1
Paul McIntosh had to have plastic surgery to repair damage to the ocular muscle controlling movement in his left eye, following the incident when he was struck by Wilfred Charles in the Commercial pub in New Street, Huddersfield on January 31.
It begins with ocular anatomy, sensory physiology and pathology, actions of the extraocular muscles, sensory adaptations to strabismus, and tests of sensory status and ocular alignment, followed by classification schemes, assessment, special tests and techniques in the assessment of alignment, abnormal head positions, and ocular muscle pareses and restrictions, and specific strabismus disorders and syndromes.
