Ability of different optical imaging devices to discriminate between healthy and glaucomatous eyes.

We compared the ability to discriminate between healthy and glaucomatous eyes of three optical imaging devices in 140 eyes from 140 subjects. No statistically significant differences were found among the AUCs of these parameters. However, AUCs were significantly higher in OCT and HRT parameters than most of GDx VCC ones. Thus, structural parameters assessed by the optical imaging devices are useful to discriminate glaucomatous damage, but showed no significant difference among the best parameters from HRT, OCT or GDx VCC.

Choroidal and optic disk metastases of a laryngeal carcinoma.

PURPOSE: To report a case of laryngeal squamous carcinoma metastatic to the eye affecting the choroid and optic nerve. METHODS: A 58-year-old man complained of sudden decrease of visual acuity in his left eye on admission to the emergency room. One year previously, he had undergone a surgical removal of laryngeal carcinoma. Funduscopic examination detected a choroidal mass in the macular area. RESULTS: After 10 days, the patient complained of pain and a diminished visual acuity and presented an exudative retinal detachment and optic nerve infiltration. CONCLUSION: Metastatic tumors are the most common intraocular malignancies, and the choroid is by far the most frequent location for the intraocular metastases. Metastases from a laryngeal carcinoma are quite unusual. Lesions affecting both choroid and optic nerve are extremely rare.

Diagnostic ability of different tools for detection of glaucoma with confocal scanning laser tomography (Heidelberg Retina Tomograph II).

We evaluated the diagnostic ability of various diagnostic tools to detect glaucomatous damage in 101 normal eyes and 102 glaucomatous eyes. Mikelberg's linear discriminant function (LDF) obtained the best sensitivity followed by our own four formulas. With respect to specificity, Burk's LDF showed better results than Mikelberg's LDF and our formulae. Several Heidelberg retina tomograph analysis tools are useful to discriminate healthy from patients with glaucoma. Alternative tools based on normative databases derived from different autochthon populations add evidence needed to support their global use.
