Eyelid abnormality

The goals of OSD treatment are to relieve symptoms, heal the ocular surface, and prevent serious complications. Treatment of dry eye generally Ms into one of three categories—tear supplementation, tear conservation, or tear stimulation—in an attempt to reestablish the tear film quantitatively and qualitatively (Box 14-1). When possible, it is important to diagnose and treat coexistent or ancillary conditions that provoke or aggravate dry eye (e.g., blepharitis, meibomian gland disease, eyelid abnormalities).

The accidental release of several tons of MIC in 1984 at Bhopal, India, resulted in a very heavy death toll (approximately 1850) and, in survivors, significant impairment of health. Immediate symptoms were difficulty in breathing, skin and eye irritation, vomiting, and unconsciousness. Only a few deaths were recorded in the first few hours, with the maximum number of fatalities occurring between 24 and 72 hours. The predominant cause of death was cardiac arrest following severe pulmonary edema. Lung function abnormalities have persisted years after exposure. Ophthalmic effects included lacrimation, lid edema, photophobia, and ulceration of the corneal epithelium. A follow-up study 3 years after exposure showed excess irritation, eyelid infection, cataract, and a decrease in visual acuity, but corneal erosion was resolved. ... 

Adverse events occurring in 3% to 9% in descending order include corneal staining/erosion, photophobia, eyelid erythema, ocular ache/pain, ocular dryness, tearing, upper respiratory symptoms, eyelid edema, conjunctival edema, dizziness, blepharitis, ocular irritation, Gl symptoms, asthenia, conjunctival blanching, abnormal vision, and muscular pain.

About 30% of adult Tangier patients present with peripheral neuropathy, the onset of which usually takes place after 10 years of age. These neuropathic symptoms may be subtle or overt, transient or permanent, and include weakness, increased sweating, diplopia (double vision), ptosis (abnormally drooping eyelids), ocular muscle palsies, and diminished or absent deep-tendon reflexes. There are two prototypes of neuropathy found in Tangier dis-... 

The combination of active drug, preservative, and vehicle usually results in a hypotonic formulation (< 290 mOsm). Simple or complex salts, buffering agents, or certain sugars are often added to adjust osmolarity of the solution to the desired value. An osmolarity of 290 mOsm is equivalent to 0.9% saline, and this is the value sought for most ophthalmic and intravenous medications.The ocular tear film has a wide tolerance for variation in osmotic pressure. However, increasing tonicity above that of the tears causes immediate dilution by osmotic water movement from the eyelids and eye. Hypotonic solutions are sometimes used to treat dry eye conditions and to reduce tear osmolarity from abnormally high values.

Evaporative loss can also occnr from abnormal ocular surfece exposure, due to incomplete blink, nocturnal lagophthalmos, exophthalmos, proptosis, cranial nerve VII palsy, lid retraction, or other eyelid position and apposition disorders. Contact lenses may also contribute to an increased tear evaporation rate. 

Irregular eyelid margins or function, irregular blinking, disturbed ocular surfece innervation, or abnormal tear film may compromise the epithelial surface. When an inoculum of sufficient quantity invades the conjimctiva, over-colonization by the infectious organism may result either from overwhelming normal flora or because the antimicrobial capabilities of the tear constituents have been exceeded. 

This chapter provides practical imormation regarding common corneal conditions that may require treatment. By nature of its anatomic proximity to and integration with other ocular and adnexal strnctnres, corneal abnormalities may result from diseases primary to the eyelids, conjunctiva, lacrimal system, episclera, and other tissues. The details of these conditions are not emphasized in this chapter thus the reader should refer to other appropriate chapters for this imormation. 

Clinically, the practitioner may observe conjimctival chemosis and erythema, abnormal eyelid position (lid retraction), lid lag, and proptosis. Conjunctival injection is most marked over the involved rectus muscles. Nervousness, palpitations, weight loss, hyperhidrosis, and heat intolerance are systemic symptoms occurring in more than 80% of hyperthyroid patients. Other signs, such as tremor, hyperreflexia, tachycardia, skin changes, stare, and eyelid lag, are observed in more than 60%. Additionally, goiter is present in more than 95% of Graves disease patients. In most cases, however, the laboratory confirmation of thyrotoxicosis is helpful to corroborate the diagnosis.

Salts of edetic acid have been reported to cause symptomatic zinc deficiency, with abnormalities of the skin, including crusted lesions of the mouth and eyelids, leuko-keratosis of the tongue, stomatitis, and a papular, pustular, erosive rash of the face and perianally, alopecia, and white bands on the nails (17,18). 

No human cases have been reported so treatment recommendations are speculative. Dermal contamination probably requires no treatment other than decontamination. For gastric contamination caused by swallowing, treatment by emesis, gastric lavage, and/or activated charcoal may be indicated. Patients should be monitored for CNS depression, ptosis (drooping eyelid), and liver functional abnormalities if significant amounts (> 8 g) have been ingested.

Ocular effects including hypersecretion of the Meibomian glands, abnormal pigmentation of the conjunctiva, and swollen eyelids have also been observed in humans occupationally exposed to PCBs. These ocular alterations almost always accompany chloracne. Ocular effects may continue to appear after exposure has ceased, possibly as a result of accumulation of the causative agent in skin adipose. 

Biological Weapon - An item of material that projects, disperses, or disseminates a biological agent including arthropod vectors. Blepharospasm - Uncontrollable winking caused by involuntary contraction of an eyelid muscle. BLPS - Ballistic / Laser Eye protection. Bradycardia - Abnormally slow heartbeat. Broken Arrows - An accident involving nuclear weapons. While it is almost impossible for the warhead to accidentally detonate, the accident may spread radioactive contamination over a wide area. 

Similar to mouse models that lack the acyl-CoA cholesterol acyltransferase-1, diacyl-glycerol acyltransferase-1, and ElovlS genes, Scdl mice exhibit cutaneous abnormalities with atrophic sebaceous glands and narrow eye fissure with atrophic meibomian glands, suggesting an important role of MUFA in skin and eyelid homeostasis. The major function of sebaceous and meibomian glands is to secrete lipid complex lubricants, termed sebum and mebum, respectively. These lubricants contain wax esters, TGs, and cholesteryl esters, and prevent the evaporation of moisture from the skin and the eyeball. 

Reports from Bhopal regarding abnormal babies, implying teratogenic effects of methyl isocyanate are variable. Births of babies with defects, such as closed anus, missing ears, meningocele, closed eyelids, and also substantive reports of a high proptntion of spina bifida, are available [31]. 

Like ptosis and eyelid disorders, abnormal ocular movements in thyroid-associated eye diseases may be consequential to abnormalities at different levels of the nervous system. Apart from myasthenia gravis described under eyefid disorders, the association of exophthalmos with ophthalmoplegia in hypothyroidism has been described. Elevated titers of thyroid antibodies suggest a possible role of autoimmunity (Brownlie et ai, 1975), but concurrent mechanical factors related to exophthalmos cannot be entirely excluded. Hence, the neurological level of involvement remains uncertain.
