The authors report anterior segment optical coherence tomography (OCT) imaging findings in a case of central toxic keratopathy following laser in situ keratomileusis (LASIK) surgery for low hyperopia. OCT imaging 1 month after surgery demonstrates that the flap thickness is maintained and the location of stromal tissue loss is just posterior to the flap in the stromal bed in the affected area. ...

Aims: To study the long term toxic effects of intraocular benzalkonium chloride (BAC). Methods: 19 patients exposed to intraocular BAC preserved viscoelastic during cataract surgery in February 1999 developed severe striate keratopathy immediately postoperatively. 16 patients, including two who underwent penetrating keratoplasty, were studied in the period April to June 2000. Ocular symptoms, v...

Tamoxifen citrate (ICI46474) is an antiestrogenic agent used in cases of disseminated breast carcinomas and as adjuvant postoperative therapy. Toxic reactions to tamoxifen, such as decreased visual acuity, bilateral macular edema, and yellow-white dots in the paramacular and foveal areas, are relatively rare (reported incidence between 0.9%-12%). In 1978, Kaiser-Kupfer and Lippman first reporte...

PURPOSE To describe the morphologic features of Fuchs corneal dystrophy and compare them with those of bullous keratopathy. METHODS This was an observational case series. The study group consisted of 32 corneal buttons with a diagnosis of Fuchs dystrophy and the comparison group consisted of 22 corneal buttons with bullous keratopathy. Morphologic analysis was performed of corneal buttons fro...

The use of preservatives in eye drops (eyewashes) has known glory at the beginning, but the side effects that they have on the ocular surface have led to a decrease of their popularity. Lachrymal film dysfunction, ocular hyperemia, dotted keratitis or toxic keratopathy were reported and analyzed in terms of pathophysiological mechanism of the role played by preservatives in ophthalmic drops (ey...

Objective. To report a case of toxic anterior segment syndrome (TASS) that was caused by inadvertent anterior chamber and cornea stromal injection with high dose gentamicin following cataract surgery. Methods. Case report. Results. We report a 72-year-old female patient who developed TASS that was caused by high dose gentamicin (20 mg/0.5 mL), which was inadvertently used during the formation o...
