Nasolacrimal duct obstruction (NLDO) is a relatively common clinical problem. Debate continues about optimal management. Intervening early and intervening late each have advantages and disadvantages. We reviewed the world literature on NLDO. We assembled information on occurrence, natural history, and results of treatment. Spontaneous remission data were used to derive the probability of continued obstruction versus age. The prevalence a hypothesized treatment-resistant form of NLDO was estimated. Symptomatic NLDO probably occurs in 5 to 6% of infants. Given a symptomatic case under the age of 14 months, the probability of spontaneous remission within the following month appears to be approximately one of three. Probe failure risk increases with age, doubling every 6 months. Increasing probe failure risk may be due to self-selection. Preliminary analysis of management strategies suggests that lacrimal duct probing at age 4 months in the office is the most cost-effective strategy. Further descriptive studies of NLDO remission and treatment are indicated.

The relationship between oral contraceptive (OC) use and eye disease was investigated through abstraction of salient data from the two large British cohort studies of the effects of OCs: the Royal College of General Practitioners' (RCGP) OC Study and the Oxford-Family Planning Association (FPA) Contraception Study. Together, these studies have accumulated over 850,000 person-years of observation since 1968 involving 63,000 women. The conditions considered in the analysis were conjunctivitis, keratitis, iritis, lacrimal disease, strabismus, cataract, glaucoma, retinal detachment, and retinal vascular lesions. The only eye disease for which there was consistent evidence of a notable increase in risk in OC users was retinal vascular lesions. The relative risk of retinal vascular lesions in OC users compared to never users was 2.0 (95% confidence interval (CI), 1.0-3.8) in the RCGP data set and 2.4 (95% CI, 0.4-9.2) in the Oxford-FPA Study. This increased risk was not concentrated in any one diagnostic category (e.g., retinal vascular occlusion, retinal vein thrombosis, retinal hemorrhage).

Rubinstein-Taybi syndrome is a constellation of clinical findings characterized by mental and motor retardation, broad thumbs and broad first toes, typical facies. Ocular and adnexal abnormalities are quite common and include antimongoloid slant of the palpebral fissures, epicanthal folds, congenital obstruction of the lacrimal excretory system, ptosis, strabismus, congenital cataract and congenital glaucoma. The authors describe the case of a 1-year-old male with the Rubinstein-Taybi syndrome associated with unilateral congenital glaucoma. The case emphasizes the importance of detailed complete ocular examinations in patients with Rubinstein-Taybi syndrome, and also highlights the occurrence of ocular abnormalities rarely associated with this disease.

During the past 2 decades, the introduction of functional endoscopic sinus surgery (FESS) has dramatically improved the treatment of sinus disorders. However, a variety of orbital complications have been reported, including optic nerve damage, hemorrhage, infection, compromise of the lacrimal drainage apparatus, and strabismus. At least 10 cases have reported damage to the medial rectus muscle. (1-8) Treatment options for such patients have been limited, especially because most are adults at risk for anterior segment ischemia after transposition of vertical rectus muscles. We describe 2 patients whose medial rectus myectomies were repaired by using nonabsorbable "hang-back" sutures in combination with a botulinum toxin (Botox) injection of the antagonist lateral rectus muscle. Good primary position alignment was achieved in both patients, and one patient was able to regain binocular function. We recommend this surgical approach, especially in patients at increased risk for anterior segment ischemia.

Rubinstein-Taybi syndrome, known also as "Broad Thumb-Hallux syndrome", was first recognized by Rubinstein and Taybi in 1963 and is characterized by somatic and ophthalmologic signs. Most commonly somatic changes are: broad thumbs and hallux, craniofacial dysmorphism, growth and psychomotor retardation. Most frequently reported eye anomalies are: antimongoloid slant of the palpebral fissures, strabismus, congenital obstruction of the lacrimal excretory system, colobomas of the iris and of the optic nerve head, ametropia.

The orbit in Graves disease undergoes expansion in soft tissue content as a result of the infiltration of orbital fat, extraocular muscles, and the lacrimal gland. Compression of the intraorbital contents leads to disorders of the lid-corneal interface, keratopathy, motility disturbances, exophthalmos, and optic neuropathy. Orbital decompression has traditionally been reserved for those patients with unremitting optic neuropathy. This article provides a historical review of orbital decompression, as well as a review of the evolution of surgical approaches toward both soft tissue and bony decompression. Recent trends in surgical management include fat decompression, more extensive posterior sculpting of the lateral wall, and direct approaches to the medial wall. Preoperative predictors of diplopia and hypoglobus are addressed, as are the various techniques that are employed to limit new postoperative strabismus. The roles of endoscopy and combined surgical techniques are also reviewed. Expanded indications for decompression and its effect on increased intraocular pressure are discussed as well.

Most penetrating or lacerating injuries of the eye in children justify examination under anesthesia to avoid further harm to an uncooperative patient. The pediatrician in doubt should merely apply a sterile dressing and have an ophthalmologist examine the injury in hospital. Nonperforating injuries may result in severe bleeding 48 to 72 hours later; this may be averted by bandaging the eyes and maintaining rest for four or five days. Removal of foreign bodies should be followed by application of antibiotic ointment and patching to prevent contamination. Congenital stenosis of the lacrimal duct may clear spontaneously or through application of decongestants and sympathomimetic drops. More severe effects, especially infection, justify probing at six months or earlier. The operation should be done under general anesthesia, preferably in hospital.Acute conjunctivitis is best treated by local application of antibiotics or sulfonamides only. Chronic infections may be better managed with the addition of corticosteroids, which reduce local inflammation and control bacterial reaction. Bacterial study should be done only if empirical antibiotic therapy fails. Bacterial desensitization may be helpful. The same methods are effective in blepharitis, aided by hygienic measures. Corticosteroids are most useful in allergic inflammations.Refractive difference is difficult to test before a child can read, and apparent defects may be due to lack of cooperation. Marked inequality of the eyes may signify organic disorder. Strabismus, on the other hand, can be detected as early as 12 or 15 months and should be treated as early as possible by proper lenses, surgery, or both. Pediatricians and parents should be aware that many children appear to have strabismus because of wide epicanthi and deep-set eyes.

Congenital eyelid malpositions can be isolated or associated with other structures such as the eyeball, ocular muscles, and lacrimal pathways. It is important to separate eyelid malpositions, which are topographical disorders, from eyelid malformations, which are constitutional morphological disorders. Only eyelid malpositions will be described in this paper, with a distinction made between static and dynamic disorders. Static disorders include epiblepharon, congenital ectropion and entropion, epicanthus, telecanthus, and centurion syndrome. Dynamic disorders group ptosis and congenital eyelid retractions. Epiblepharon is characterized by the absence of adhesion between the lower eyelid retractors and the orbicularis-skin layer, which allows the anterior lamella to roll over. Congenital entropion and ectropion are very rare. They most often require surgical treatment. Epicanthus involves a semi-lunar fold of skin extending from the upper eyelid across the medial canthal area to the margin of the lower eyelid. Four types (supra-ciliaris, palpebralis, tarsalis and inversus) of epicanthus are described. Treatment requires surgery. Telecanthus is defined as an increased distance between canthi. Primary telecanthus results from attenuation of the medial canthal tendons and is usually associated with other soft tIssue abnormalities such as epicanthus or blepharophimosis, or is seen after trauma. Secondary telecanthus is caused by underlying bony malpositions with an abnormal separation between the orbits because of an increased thickness of the interorbital bones such as that seen in hypertelorism or in other complex craniofacial syndromes. Euryblepharon is distinguished by an enlargement of the horizontal palpebral fissure associated with enlarged eyelids. The etiology is unknown and patients may benefit from surgery. Congenital ptosis is characterized by a deficiency of the levator muscle. They are most often unilateral and isolated. When associated with other abnormalities such as squint, synkinesis, blepharophimosis, or craniofacial syndromes, surgical treatment may require several-stage procedures. On the other hand, isolated congenital ptosis is usually treated in childhood (3-6 years) in a single stage. Congenital eyelid retractions may affect either the lower or the upper eyelid. They make up a rare condition and most cases are associated with craniofacial syndromes such as Crouzon or Apert syndromes. Upper eyelid retractions may spontaneously improve in some cases, but lower eyelid retractions do not. Treatment requires surgery, depending on the corneal consequences.

The authors report a family with familial Bell's palsy affecting seven individuals, six of whom are females. This is a distinct subtype of Bell's palsy with a predilection for juvenile females, previously reported only very rarely. In conjunction with a review of the literature, this case suggests that this phenotype carries with it a greater risk of serious complications affecting the eyelids and lacrimal gland. These carry significant functional and cosmetic implications owing to aberrant regeneration of the seventh, sixth and possibly third cranial nerves, chronicity and relapses. Clinical features include synkinesis of the eyelids with the orbicularis oris causing synkinetic ptosis, recurrent paralytic ectropion, paralysis of facial muscles of expression with dry eye, hyperlacrimation (crocodile tears), and transient strabismus. Clinically, the decision to offer surgery in place of conservative treatment should consider the natural history of chronicity and relapses often seen with this subtype of familial Bell's palsy. Botulinum toxin injections are especially versatile in managing the complications associated with this phenotype.

Previously reported cases of lacrimal outflow dysgenesis have frequently been associated with developmental anomalies or systemic syndromes, raising potential red flags in affected children. We report an unusual case of familial punctal atresia with apparent genetic linkage to bilateral preauricular sinuses without any such comorbid syndromic features.
