OBJECTIVE Optic disk drusen are relatively benign lesions of the eye but can cause visual symptoms and may occasionally mimic papilledema on funduscopy. We studied the range of sonographic findings and determined if sonography can be used to diagnose this condition in the absence of typical funduscopic findings. SUBJECTS AND METHODS Sonography of the eyes was performed in 12 patients with kno...

The optic disk and the RNFL are the principal sites of apparent glaucomatous damage which precedes glaucomatous visual field alterations. RNFL defects are known to precede detection of visual field defects by approximately 6 years. Accurate early detection and monitoring of ONH and RNFL defects has become the prime focus of effective management of glaucoma. Optical coherence tomography employs ...

A new fiber optic microsensor has been developed for pressure measurement. The pressure microsensor is extremely small (360 micro m). Performance characteristics of the microsensor were evaluated over a pressure range from 0 to 250mmHg. Five sensors were compared to a National Institute of Standards and Technology traceable reference pressure. The microsensor had an accuracy, repeatability, and...

purpose: to report a relatively rare case of familial exudative vitreoretinopathy (fevr). patient and findings: a 13-year-old boy referred with decreased visual acuity of both eyes, specially right eye from 6 years ago. he had several ophthalmologist and optometrist visits and spectacle prescription without any improvement of vision. best corrected visual acuity (bcva) was 25 cm of count finger...

A 25-year-old man with X-linked retinoschisis presented with multiple giant optic nerve head drusen and multiple retinal drusenoid deposits in one eye. There was an area of coarse pigmentation in the lower half of the retina, with convex upper borders extending on either side of the optic disc, suggestive of a spontaneously resolved retinal detachment. The possible aetiopathogenesis of such occ...

PURPOSE To measure the tissue pressure gradient through the optic disk and to determine the relationship between intraocular, cerebrospinal fluid, and retrolaminar tissue pressures. The relationship of optic nerve subarachnoid space pressure to intracranial cerebrospinal fluid pressure also was explored. METHODS Micropipettes coupled to a pressure transducer were passed through pars plana and...

To report a rare case of bilateral morning glory disc anomaly and to evaluate the Angio OCT characteristics of macula and the optic disk in a case of bilateral morning glory disk anomaly.

E-mail: [email protected] Introduction. Optic disk pit has been considered as coloboma located, as a rule, near temporal part of the optic disc. Central serous retinal detachment develops in 50 % of patients. The purpose of the present study was to show practically the possibility to use laser coagulation as an entire method for treatment of optic disc pit complicated by serous neuroepithelia...
