To describe two patients with nasolacrimal duct obstruction (NLDO) caused by ectopic eruption of teeth. The literature concerning nasal and other unusual ectopic sites of tooth eruption is reviewed. ⋯ These cases suggest that ectopic eruption of teeth should be added to the differential diagnosis of NLDO. Surgical removal of the ectopic teeth compressing the nasolacrimal duct results in resolution of the lacrimal drainage obstruction.

Until recently, inhaled corticosteroids were not considered to cause elevated intraocular pressure (IOP), although topical and oral corticosteroids have been shown to do so in susceptible individuals. The authors aimed to (1) identify whether an association existed between inhaled corticosteroid use and elevated IOP or open-angle glaucoma and (2) determine whether this effect may have a genetic basis. ⋯ These findings suggest an association between ever use of inhaled corticosteroids and a finding of elevated IOP or glaucoma in subjects with a glaucoma family history. Patients being treated with inhaled corticosteroids need review by an ophthalmologist if they report a glaucoma family history.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
The efficacy and safety of the dorzolamide-timolol combination versus the concomitant administration of its components.
To evaluate whether a fixed combination of 2% dorzolamide and 0.5% timolol given twice daily showed equivalent efficacy to the concomitant administration of 2% dorzolamide given three times daily and 0.5% timolol given twice daily in patients whose intraocular pressure (IOP) remained elevated during monotherapy with 0.5% timolol twice daily. ⋯ The IOP-lowering effect of the dorzolamide-timolol combination is comparable to that of dorzolamide three times daily plus timolol twice daily and is maintained for up to 1 year. The dorzolamide-timolol combination provides clinically important reduction in IOP relative to baseline treatment with timolol alone and is generally well-tolerated for up to 1 year.

To prospectively determine the accuracy of helical computed tomography (CT) and multiplanar reconstruction and its value in surgical planning for the management of ocular trauma with suspected intraocular and orbital foreign bodies using surgical and clinical follow-up findings as the gold standard. ⋯ Helical CT axial scanning with multiplanar reconstruction is accurate at detecting and localizing intraocular and orbital metallic, glass, and stone foreign bodies. This imaging method aids the surgeon in choosing the surgical approach to retained intraocular and orbital foreign bodies.

Randomized Controlled Trial Clinical Trial
Efficacy of supplementary intracameral lidocaine in routine phacoemulsification under topical anesthesia.
To determine whether the routine use of supplementary intracameral lidocaine has any benefit over topical anesthesia alone when performing phacoemulsification surgery. ⋯ In this study, the routine use of intracameral lidocaine as a supplement to topical anesthesia was shown not to have a clinically useful role.
