Traumatic globe luxation: A case report.

Globe luxation is a rare clinical event. Most of the cases are usually traumatic, although spontaneous globe luxation has also been reported. The majority of the posttraumatic cases are usually associated with the injury or fracture of the bony orbit. We report here a case of globe luxation that occurred per se without any injury to the orbital or maxillo‑facial bony structures.

Ocular morbidity among children at a tertiary eye care hospital in Kolkata, West Bengal.

Eye diseases in childhood are important causes of medical consultation and it affects learning ability, adjustment in school and personality. To determine the pattern of ocular morbidity a cross-sectional observational study was conducted among 714 children, attending Ophthalmology department at a tertiary eye care center in Kolkata, West Bengal. All the children less than 15 years of age, attending in Unit II outpatient department were selected by complete enumeration method for duration of one year (January-December 2010). Distribution of association was analyzed by Chi-square test and difference between two proportions was calculated by z test for proportions. The common ocular morbidity were refractive errors (23.67%) followed by allergic conjunctivitis (17.23%), infection of the eye and adnexa (15.13%), ocular trauma (12.74%), and congenital eye diseases (13.59%). Majority of ocular morbidity is treatable and need early attention through eye screening cum intervention program beginning right from the childhood.

Effect of dacryocystorhinostomy on systemic adverse effects of topical timolol maleate.

Purpose: To evaluate whether transformation of the naso-lacrimal passage as happens after dacryocystorhinostomy (DCR) operation has any effect on the systemic adverse effects of topically administered timolol maleate. Materials and Methods: Fifty otherwise healthy adult patients without any prior history of cardiac or pulmonary problems scheduled for elective DCR surgery received a drop of timolol maleate 0.5% on the healthy eye. This eye served as a control. Six weeks after successful DCR surgery, the operated eye received the same medication. Parameters compared included intraocular pressure (IOP), pulse rate, blood pressure and forced expiratory volume in the first second (FEV1) findings. Observations: Post DCR patients showed an increased incidence of reduced pulse rate and FEV1. Conclusion: Timolol maleate ophthalmic preparation should be used with caution in post-DCR patients.

A case of unusual presentation of Takayasu's arteritis.

Takayasu's arteritis is a chronic inflammatory disease of the large and medium-sized arteries. It commonly involves the aorta with its branches and the pulmonary arteries. The retinal hemodynamics suggest that the carotid artery involvement causes diminished retinal blood flow. This is the pathogenetic mechanism of Takayasu's retinopathy with characteristic features of microaneurysms, arterio-venous anastomosis and non-perfused retinal areas. Our case presented as branch retinal artery occlusion with collaterals and iris neovascularization. The branch retinal artery, a small retinal artery occlusion in our case is an unusual presenting feature of Takayasu's aorto-arteritis.

A rare cause of nasolacrimal duct obstruction: Dentigerous cyst in the maxillary sinus.

The most common abnormality of the lacrimal drainage system is congenital or acquired nasolacrimal duct obstruction. The causes of acquired nasolacrimal duct obstruction may be primary or secondary. The secondary acquired obstructions may result from infection, inflammation, neoplasm, trauma or mechanical causes. The maxillary sinus cysts usually obstruct the nasolacrimal duct mechanically. Dentigerous cysts are one of the main types of maxillary cysts. These cysts are benign odontogenic cysts which are associated with the crowns of unerupted teeth. The clinical documentations of mechanical nasolacrimal duct obstructions due to a dentigerous cyst in the maxillary sinus are very rare in literature. In this case report, we describe a dentigerous cyst with a supernumerary tooth in the maxillary sinus in an 11-year-old male child causing an obstruction to the nasolacrimal duct. The case was successfully managed surgically by Caldwell Luc approach.

A case of Goldenhar-Gorlin syndrome with unusual association of hypoplastic thumb.

A case of Goldenhar-Gorlin syndrome in a seven-month-old male infant presented with the features of epibulbar dermoid, microtia and hemifacial microsomia associated with thumb defect. The dermoid was bilateral and microtia was unilateral. Preauricular appendages and pits were double and single respectively on both the sides. Hemifacial microsomia was unilateral and was associated with cleft lip, macrostomia, dental misalignment, large tongue and high arched palate. The association of hypoplastic thumb with Goldenhar-Gorlin syndrome has not been documented in the past.

Conjunctival intra-epithelial neoplasia in a young Indian male with human immunodeficiency virus (HIV) infection.

Conjunctival intra-epithelial neoplasia is a disease of the elderly but recently this ocular surface tumour has been observed in younger age group specially who are serologically human immunodeficiency virus (HIV)-positive. Here a case of conjunctival intra-epithelial neoplasia of a 38-year-old male who was HIV-positive from Kolkata is reported. The patient presented with a growth at limbus in his left eye. Excision of the mass under local anaesthesia was done. Biopsy report confirmed conjunctival intra-epithelial neoplasia. The serological tests for HIV were found positive.

Klippel-Feil syndrome: a case report and current understanding of molecular genetic background.

A case of Klippel-Feil syndrome in a 12-year-old boy presentingwith the features of low set posterior hairline, short webbed neck, scoliosis and Sprengel's deformity associated with upper eyelid coloboma and pre-auricular appendages is described. Radiologically there was evidence of maldeveloped cervical and upper thoracic vertebrae associated with elevated scapula. The association of the eyelid defect and pre-auricular appendages has not been documented in the past. The current literatures based on the recent advances in understanding of molecular genetic control over embryonic development of the cervical spines were reviewed.

Atypical presentation of a primary iris cyst.

Iris cysts are rare clinical occurrences. They are more commonly seen secondary to trauma, medications, or parasitic infestations; or may herald the onset of an intra-ocular malignancy. Primary iris cysts without any clinically detectable aetiology are rare ophthalmic curiosities. The cyst presented here is atypical in its size, shape and location.
