odern cataract surgery aims not only to remove lens opacities but also to achieve correction of any refractive error. In addition to restoration of uncorrected visual acuity, correction of preexisting astigmatism is also important, and treatment options for this purpose include corneal limbal relaxing incisions, excimer laser photoablation and toric intraocular lens (IOL) implantation.

Twenty-four cases of an acute ophthalmia of cattle have been observed. The infection is characterized by photophobia, severe congestion of the vessels of the eyeball, conjunctivitis, congestion and edema of the membrana nictitans, edema of the eyelids, accompanied by a thick, yellowish white mucus or mucopurulent exudate. In certain cases corneal ulcers and extensive corneal opacities developed...

PURPOSE To report a case of severe bilateral deep stromal neovascularization and opacification associated with unmonitored contact lens wear. DESIGN Observational case report. METHODS A 46-year-old woman who had been using hydrogel contact lenses bought on the Internet without a prescription for 5 years was found to have dense, bilateral corneal opacities with deep stromal neovascularizatio...

PURPOSE To describe a visually evoked potential (VEP) examination performed on a patient with a keratoprosthesis. METHODS We report the case of a 60-year-old patient with a Fyodorov-Zuev keratoprosthesis in the right eye complained of gradual visual deterioration in that eye. His past medical history consisted of failed corneal graft procedures due to corneal dystrophy and an Ahmed valve impl...

IN 1955 one of us (H. E. H.) saw a patient in whom the complaint of haloes arose from deposits in the corneal epithelium resembling those described by Mann (1947) in workers engaged in the manufacture of atebrine. This patient was at that time under treatment for actinic dermatitis with chloroquine and the similarity of the corneal changes to those described by Mann suggested that a relationshi...

Since its discovery in the years of the French Revolution, the field of keratoprostheses has evolved significantly. However, the path towards its present state has not always been an easy one. Initially discarded for its devastating complications, the introduction of new materials and the discovery of antibiotics in the last century gave new life to the field. Since then, the use of keratoprost...

BACKGROUND Amiodarone, class III anti-arrhythmic was originally introduced to treat angina pectoris, was later approved by FDA in 1985 for the treatment of ventricular arrhythmias. Despite its anti-arrhythmic properties, amiodarone is associated with side effects such as thyroid dysfunction, corneal deposits, bluish skin discoloration, neuropathy and pulmonary toxicity. Amiodarone induced pulmo...

A 41-year-old white woman was referred to our Department to rule out the presence of a Fuch's corneal dystrophy. On slit-lamp biomicroscopy, small bilateral punctuate opacities appearing mostly in the posterior stroma were observed, suggesting a differential diagnosis of pre-Descemet's dystrophy as opposed to Cornea Farinata.Confocal microscopy in the central cornea of both eyes revealed the no...

Although the history of ophthalmic surgery can be dated back thousands of years with operations to treat cataracts, surgery involving the vitreous cavity has only been reported for less than 50 years. The initial description of major vitreous surgery was introduced by David Kasner in 1969 (Kasner, 1969). He described excision removal of the vitreous using a sponge and scissors, under an open sk...

Keratectomy. By Dimitri Azar, Roger Steinert, and Walter Stark. Philadelphia, PA: Williams and Wilkins; 1997; 214 pp. $79.00. Phototherapeutic keratectomy (PTK) has been developed to remove superficial corneal opacities and irregularities. In the foreword, Claus H. Dohlman, Professor of Ophthalmology at Harvard, whimsically asks the question, “Will a quick shave with the excimer laser solve the...
