The authors review their long-term results and complications with the use of botulinum A toxin in the treatment of facial dystonias. Two hundred thirty-two patients in three diagnostic groups--essential blepharospasm, hemifacial spasm, and Meige's syndrome--were treated with botulinum A toxin. A total of 1044 treatments were given over a 4-year period. A reduction in orbicularis spasm intensity was noted in 1012 (96.9%) treatments (mean duration, 13.3 weeks). There was no clear relationship between toxin dose and the amount of spasm reduction or duration of response, and average duration of beneficial effect remained constant from the first through the twelfth injections. Complications occurred in 236 (22.6%) treatments. In most cases, these were local and transient. Symptomatic dry eye was the most common side effect, noted in 7.5% of cases. Ptosis was reported in 7.3% of treatments and photophobia in 2.5%. Diplopia involving the inferior oblique or lateral rectus muscles was seen in less than 1% of cases. There were no differences in degree of response or in complications among the three diagnostic groups, although there was a slight difference in duration of effect. Patients who had undergone previous eyelid surgery for blepharospasm did not respond differently from those without prior surgery.

Gel Tears, a clear, semisolid formulation of synthetic, high molecular weight, cross-linked polymers of acrylic acid, persists in the conjunctival sac for hours after topical instillation, slowly melting while absorbing fluid and retaining it locally. In the present study of 55 patients (106 eyes) with severe dry eyes, who were unable to obtain ocular comfort with frequent administration of a wide variety of commercially available artificial tear preparations, 78% were improved by Gel Tear therapy. Subjective symptoms such as burning, stinging, foreign body sensation, dryness, and photophobia were significantly (P less than 0.001) alleviated, while objective signs concurrently improved but to a lesser degree. No patient required Gel Tears more often than four times daily. Most maintained optimal comfort on a dose of twice daily or less, and several patients previously unable to obtain ocular comfort with hourly administered conventional artificial tears required Gel Tears less than once a day.

Psoriasis is a common skin disease which may be treated with 8-methoxy psoralen and long-wave ultraviolet light (PUVA). Eye protection is provided during and after treatment to prevent the development of photokeratitis and cataracts. Fifteen patients, treated with medication and ultraviolet A (UVA) had an initial complete eye examination and a repeat examination after each treatment. No patients developed cataracts but almost one-half of the patients had a mild form of photokeratoconjunctivitis. The ocular manifestations included photophobia, conjunctivitis, keratitis, and dry eyes. Tear break-up time was reduced significantly immediately after treatment for two patients but returned to normal 8 hr later. Dermatologists who employ PUVA treatments should be concerned about photokeratoconjunctivitis and the dry-eye ocular manifestations included photophobia, conjunctivitis, keratitis, and dry eyes. Tear break-up time was reduced significantly immediately after treatment for two patients but returned to normal 8 hr later. Dermatologists who employ PUVA treatments should be concerned about photokeratoconjunctivitis and the dry-eye ocular manifestations included photophobia, conjunctivitis, keratitis, and dry eyes. Tear break-up time was reduced significantly immediately after treatment for two patients but returned to normal 8 hr later. Dermatologists who employ PUVA treatments should be concerned about photokeratoconjunctivitis and the dry-eye syndrome.

Many common ophthalmologic conditions may present as a red eye. Most are not vision-threatening and can be easily treated. Vision-threatening symptoms and signs include sudden diminution in visual acuity, ocular pain, photophobia and the presence of circumcorneal injection (the so-called cilary flush) on examination. Corneal, uveal tract and anterior chamber problems often require ophthalmologic consultation, but these conditions are less common than blepharitis, lid problems, dry eyes and conjunctivitis.

We conducted a prospective, randomised, single-masked study comparing the safety and efficacy of polyacrylic acid 0.2% (PAA) and polyvinylalcohol 1.4% (PVA) in 85 patients (PAA 43, PVA 42) with dry eyes. The two groups were similar in patient demographics and study parameters at baseline. With treatment, the reduction in total symptoms (gritty or foreign body sensation, burning sensation, dry eye sensation, photophobia, others) and signs (conjunctival hyperaemia, ciliary injection, corneal and conjunctival epithelial staining) score on PAA was significantly greater than that on PVA at both two and four weeks. The daily frequency of instillation of PAA was significantly less than that of PVA on 16 of the 27 (59%) study days. For overall local tolerance there was a significant preference for PAA compared to PVA by both patients and doctors. Only one patient on each treatment had an adverse event and neither was serious. PAA (Viscotears) was as safe as, but better tolerated and more effective than PVA in the treatment of dry eye conditions.

Patients with cancer are often prescribed chemotherapeutic substances that can be extremely oculo-visual-toxic in nature. Over the past several years, advances in cancer treatment have resulted in increased survival rates and patient longevity. Unfortunately, greater survival rates and longevity mean increased exposure to potentially harmful oculo-toxic substances and a higher incidence of oculo-visual side effects. Patients receiving chemotherapy may complain of symptoms that can imitate functional disorders such as blurred vision and photophobia (i.e. disorders of accommodation) and also include dry eyes or other symptomology commonly associated with disorders of the primary eye care system. These deleterious side effects affect the patient's quality of life and warrant our attention. It is essential that eye and vision care professionals appropriately diagnose and manage these induced disorders. This review presents the oculo-visual side effects of commonly used chemotherapeutic agents, the available treatment options when these unwanted side effects occur, and when known, the mechanism by which these agents cause oculo-visual toxicity.

This review updates understanding and research on blepharospasm, a subtype of focal dystonia. Topics covered include clinical aspects, pathology, pathophysiology, animal models, dry eye, photophobia, epidemiology, genetics, and treatment. Blepharospasm should be differentiated from apraxia of eyelid opening. New insights into pathology and pathophysiology are derived from different types of imaging, including magnetic resonance studies. Physiologic studies indicate increased plasticity and trigeminal sensitization. While botulinum neurotoxin injections are the mainstay of therapy, other therapies are on the horizon.

Eyes are very sensitive to sulfur mustard (SM) gas because they have wet surfaces. The severity of ocular damage is related to the dose and duration of exposure to SM, and recovery may take up to several years after the exposure. We conducted a large cohort study to evaluate the ocular signs and symptoms of 367 chemical war victims in Sardasht City, Iran, 20 years after their exposure to mustard gas. The results of these chemical war victims (i.e., the cases) were compared with the results for 128 unaffected civilians (i.e., the controls). Photophobia was the most significant symptom in the cases (36.8%) (compared with 20.3% in the controls) (p < or = .001). Ocular surface discomfort (burning, itching, and redness) was the second most significant symptom in the cases (29.2%) (compared with 19.5% in the controls) (p = .034). Other symptoms such as foreign-body sensation, tearing, pain, blurring of vision, and dry eye sensation were not significantly different between the 2 groups. In the slit-lamp findings, bulbar conjunctival abnormality was the most significant sign in the cases (9.3%) (compared with 1.6% in the controls) (p = .004). Limbal tissue changes were the second most significant sign in the cases (3.0%) (compared with 0.0% in the controls) (p = .048). Other slit-lamp findings related to tearing and abnormalities in the lids and cornea were not significantly different between the 2 groups. Our findings in the present study showed that photophobia and ocular surface discomfort (burning, itching, and redness) were the most significant symptoms. In addition, bulbar conjunctival abnormalities and limbal tissue changes were the most significant signs among the sulfur mustard chemical war victims.

Stevens-Johnson syndrome and its more severe variant, toxic epidermal necrolysis, have relatively low overall incidence; however, this disease presents with high morbidity and mortality. The majority of patients develop ocular inflammation and ulceration at the acute stage. Due to the hidden nature of these ocular lesions and the concentration of effort toward life-threatening issues, current acute management has not devised a strategy to preclude blinding cicatricial complications. This review summarizes recent literature data, showing how sight-threatening corneal complications can progressively develop from cicatricial pathologies of lid margin, tarsus, and fornix at the chronic stage. It illustrates how such pathologies can be prevented with the early intervention of cryopreserved amniotic membrane transplantation to suppress inflammation and promote epithelial healing at the acute stage. Significant dry eye problems and photophobia can also be avoided with this intervention. This new therapeutic strategy can avert the catastrophic ophthalmic sequelae of this rare but devastating disease.

Blepharitis is a chronic inflammatory process of the eyelid margin. It is a common eye disorder throughout the world and can affect any age group. It may be associated with several systemic diseases, particularly rosacea and seborrheic dermatitis, and is related to other ocular conditions like dry eye, chalazion, conjunctivitis, and keratitis. Common symptoms associated with blepharitis are burning sensation, irritation, tearing, photophobia, blurred vision, and red eyes. Clinical examination reveals the presence of scurf, telangiectatic vascular changes of the eyelid margin, inspissated meibomian glands, conjuntival hyperemia, punctuate keratopathy, cornea vascularization, and ulceration. Patients with longstanding chronic blepharitis may present hypertrophy of the lid margin, scars, madarosis, trichiasis, and poliosis. Treatment of blepharitis is long and unsatisfactory. Long-term commitment to eyelid hygiene is essential. Other treatment options are discussed.
