PURPOSE Trachomatous trichiasis (TT) is usually described as a cicatricial entropion of the upper lid; however, other forms of trichiasis have been reported. This variation in clinical phenotype is potentially important for treatment guidelines. Therefore, this study was conducted to investigate the range of disease type and severity encompassed by TT. METHODS Individuals presenting with TT t...

PURPOSE Ocular perforation during lid anesthesia is rarely reported. We describe here a case of inadvertent corneal perforation and traumatic cataract that occurred during lid anesthesia in a procedure for hordeolum removal. METHODS A 33-year-old woman presented with a sudden visual loss of her left eye. She had undergone hordeolum removal the day before at a local clinic. On ophthalmologic e...

Monocular deprivation experiments can be used to distinguish between different ideas concerning properties of cortical synaptic plasticity. Monocular deprivation by lid suture causes a rapid disconnection of the deprived eye connected to cortical neurons whereas total inactivation of the deprived eye produces much less of an ocular dominance shift. In order to understand these results one needs...

PURPOSE External dacryocystorhinostomy is routinely performed through a cutaneous vertical incision placed on the lateral aspect of the nose. The lower eyelid crease approach has been seldom reported. The purpose of this study is to report the cosmetic and functional results of the lid crease approach for external dacryocystorhinostomy in a series of patients. METHODS Prospective, interventio...

It has recently been reported that lid closure in monkeys, whether monocularly or binocularly performed, leads to an axial enlargement of the eye, resulting in a high myopia (Wiesel and Raviola, i?77. 1978). Using a similar experimental procedure in monkeys Von Noorden and Crawford (1978) were unable to repeat these results. Slight myopia was also obtained in tree shrews similarly operated. alt...

1. Eleven kittens were deprived of vision in one eye until the age of between 5 and 14 weeks. Their eyes were then reverse-sutured, they were allowed to survive for a further 3-63 days, and their brains were then examined histologically. 2. Measurement of the cross-sectional area of cells in the lateral geniculate nucleus (LGN) showed that when the reversal of lid suture was performed at the ag...

PURPOSE To study the metrics of lid saccades in blepharoptosis and to distinguish any differences in the dynamics of eyelid movements that are related to the cause of blepharoptosis and to aging. METHODS The lid and vertical eye saccades of 7 patients with congenital blepharoptosis and those of 18 patients with aponeurogenic blepharoptosis, either involutional or rigid-contact-lens-induced, w...

BACKGROUND A chief morbidity of Graves eye disease is upper eyelid retraction that results in exposure keratopathy and cosmetic deformity. OBJECTIVE To assess the efficacy of graded anterior blepharotomy to treat upper eyelid retraction. METHODS Fifty eyelids of 32 patients with Graves eye disease-associated upper eyelid retraction, causing symptomatic ocular exposure, were treated with gra...
