OBJECTIVE: We report 3 cases of intraoperative floppy-iris syndrome (IFIS) during cataract surgery in patients without a history of selective α1-blocker use but with a long-term history of antipsychotic drug use. We reviewed previously reported cases of antipsychotic drug-associated IFIS cases. DESIGN: Observational case series. RESULTS: In case 1, bilateral IFIS developed in a 39-year-old man with chronic angle-closure glaucoma. He had used several classes of antipsychotic drugs to treat schizophrenia, including the first-generation antipsychotic drugs haloperidol and chlorpromazine, the dopamine system stabilizer aripiprazole, the dopamine serotonin antagonists olanzapine and quetiapine, and the serotonin dopamine antagonists risperidone and blonanserin for 7 years...

OBJECTIVE: Previous research has suggested a link between typical antipsychotic use and the development of cataracts, but the association between atypical antipsychotics and cataracts remains unclear in schizophrenia (SZ). METHODS: A retrospective nested case-control study was conducted using data from the National Health Insurance Database of Taiwan between the year of 2000 and 2011. A total of 2144 SZ patients with cataracts and 2222 controls matched for age, sex, and index date were included...

The worldwide situations of drug safety have changed dramatically. Drugs are used based on the evaluation of safety data collected in clinical practice worldwide. US Food Drug Administration collects spontaneous reports and requires manufacturers to report adverse drug reactions (ADRs) of US marketed drugs occurring worldwide. These worldwide data are available through the Adverse Event Reporting System (AERS) (about 4.1 million reports on about 3,073,340 patients, for 13 years: 1997.4th qr-2010.4th qr.). The current issues are how to analyze and utilize such large-scale safety data...

Several classes of drugs have potential to cause an elevation of IOP which may occur either by an open-angle mechanism or a close-angle mechanism. Drug-induced elevation of IOP is commonly has an open-angle mechanism. The most commonly recognized medications associated with this mechanism are the corticosteroids. Acute angle closure glaucoma is a potentially blinding side effect of local and systemic drugs, including antipsychotic drugs, antidepressants, monoamine oxidase inhibitors, antihistamines, antiparkinsonian agents, antispasmolytic drugs, mydriatic agents, the sympathetic agents and botulinum toxin, especially in individuals with predisposing narrow angles of the anterior chamber...

Cannabinoid compounds have widely been employed because of its medicinal and psychotropic properties. These compounds are isolated from Cannabis sativa (or marijuana) and are used in several medical treatments, such as glaucoma, nausea associated to chemotherapy, pain and many other situations. More recently, its use as appetite stimulant has been indicated in patients with cachexia or AIDS. In this work, the influence of several molecular descriptors on the psychoactivity of 50 cannabinoid compounds is analyzed aiming one obtain a model able to predict the psychoactivity of new cannabinoids...

All psychotropic medications have the potential to induce numerous and diverse unwanted ocular effects. Visual adverse effects can be divided into seven major categories: eyelid and keratoconjunctival disorders; uveal tract disorders; accommodation interference; angle-closure glaucoma; cataract/pigmentary deposits in the lens and cornea; retinopathy; and other disorders. The disorders of the eyelid and of the keratoconjunctiva are mainly related to phenothiazines and lithium. Chlorpromazine, at high dosages, can commonly cause abnormal pigmentation of the eyelids, interpalpebral conjunctiva and cornea...

Chlorpromazine is known to deposit in ocular tissues when taken at high doses for prolonged periods. Chlorpromazine therapy in a 59-year-old schizophrenic man with a cumulative dosage exceeding 2500 g resulted in multiple white deposits in both corneas especially in the endothelium. Confocal microscopy revealed significant pleomorphism and polymegethism of endothelial cells. The anterior lens capsules opacities were star-shaped and concentrated in the centre. Because of cataract and chronic angle closure glaucoma our high-myopic patient underwent surgery, and light microscopic evaluation of the obtained anterior lens capsule during cataract surgery showed golden brown cytoplasmic deposits in the central epithelial cells and capsule...

While beneficial therapeutically, almost all medications have untoward effects on various body tissues and functions, including the eye in which organ toxic reactions are readily detectable. Every part of the eye and all ocular functions could be affected adversely. In this review, we describe the most commonly recognized drug-induced ocular disorders, their specific clinical features, the medications that can cause the problem, the differential diagnosis and possible mechanisms of action, as well as guidelines for the management of the adverse reactions...

BACKGROUND: Although the core feature of dementia is progressive cognitive disruption, non-cognitive behavioural problems are expressed in most patients with dementia during the course of their illness. While psychotropic drugs are frequently used to control behavioural symptoms, comorbidities, which are very common in the geriatric population, could often limit their use. Gabapentin may be a potential treatment in such situations. METHODS: In this open, baseline comparison study 20 patients with probable Alzheimer's disease with behavioural alterations and serious comorbidities (paralytic ileus, open-angle glaucoma, ischaemic cardiopathy, hepatic failure or severe prostatic hyperplasia) received gabapentin for 15 months...

BACKGROUND: The hypothesis that exposure to traumatic events may sensitize or kindle limbic nuclei has led to efforts to treat posttraumatic stress disorder (PTSD) with anticonvulsants. Based on the kindling hypothesis of PTSD, this open-label study assesses clinical response to topiramate as a potential treatment for DSM-IV PTSD. METHOD: A naturalistic data review was conducted of medical records of all adult outpatients (9 men. 26 women symptomatic for a mean +/- SD of 18 +/- 15 years with DSM-IV chronic civilian PTSD) treated with topiramate, 12...

Neuropsychiatric agents may adversely affect the eye in various ways. The more frequently encountered effects include corneal oedema and pigmentary changes in the lens and cornea which are induced by phenothiazine derivatives; thioridazine-induced retinopathy; tricyclic antidepressant-induced accommodation interference and glaucoma; and lithium carbonate-induced exophthalmos and papilloedema. Several adverse effects, such as corneal oedema, retinopathy and glaucoma, are vision-threatening, and patients often fail to describe their symptoms properly...

Haloperidol, a dopaminergic antagonist, was found to be very effective in suppressing the intraocular pressure recovery curve of rabbits infused with 20% saline intravenously. Haloperidol was at least equipotent, if not more potent, in lowering IOP and had much longer duration of action compared with timolol maleate. In the cat model, haloperidol increased aqueous humor (AH) outflow initially, followed by a long-lasting suppression of AH formation. Since haloperidol does not block beta-adrenergic receptors and the ophthalmic dose required to lower IOP is only 6...

A group of dopamine antagonists have been studied for their ability to suppress the intraocular pressure (IOP) recovery rate of rabbits infused with hypertonic saline. All dopamine antagonists examined were either equipotent or more potent than beta-adrenergic blocker, timolol, to lower the IOP in the following order: haloperidol greater than moperone = trifluperidol greater than clofluperol = pipamperone = lenperone = timolol. Contrary to timolol, haloperidol, moperone and trifluperidol relaxed histamine pretreated guinea pig tracheal muscle at doses as low as 0...
