Factors Influencing Contrast Sensitivity Function in Myopic Eyes
PURPOSE To evaluate the factors affecting the area under the log contrast sensitivity function (AULCSF) in healthy myopic eyes. METHODS We retrospectively examined 201 eyes of 201 consecutive subjects (age, 31.8 ± 7.4 years (mean ± standard deviation)) with myopic refractive errors of -1.25 to -8.25 diopters (D). From the contrast sensitivity data, the area under the log contrast sensitivity ...
متن کاملEvaluation of lacrimal drainage system by radionuclide dacryoscintigraphy in patients with epiphora
Introduction: This study was done to determine the site of obstruction in lacrimal drainage system in Asian patients suffering from epiphora and to determine the transit time taken for the tracer material to reach the lacrimal sac and the nasal cavity. Methods:Dacryoscintigraphy was performed using radionuclide technetium-99m pertechnetate (99m...
متن کاملEpiphora and the bony naso-lacrimal canal.
IT is possible to obtain a radiographic view of the naso-lacrimal canal "end-on" by directing a beam of x-rays down the axis of the canal to a film held horizontally in the mouth: the centre of the film is placed near the site of the first molar tooth (Brunetti, 1930; Kopylow, 1930; Toth, 1933), or the second pre-molar. Examples of such radiographs are shown in Figs 1, 2, and 3. The present inv...
متن کاملSalivation induced better lacrimal gland function in dry eyes.
The dry eye syndrome is a common eye symptom causing blurry vision. To meet the demand of the modem world students and professionals are compelled to expose themselves to the computer screen for long stretch of time, which is one of the causes of dry eye. It is not always feasible to instil eyes with artificial tears time to time to protect them from dryness. Rather to adopt any simple physiolo...
متن کاملDacryoliths causing intermittent epiphora associated with a patent lacrimal system.
We present two patients with dacryoliths and patent lacrimal drainage with intermittent tearing and without infection. Dacryoliths can be present in the lacrimal sac or lacrimal duct without acute or chronic inflammation. In these cases, we believe dacryolith formation was a causative factor of intermittent epiphora even with a patent drainage system, and we propose that dacryoliths and even fu...
