PURPOSE To determine the sensitivity of the Seoul National University (SNU) computerized color vision test for detecting diabetic macular edema. METHODS From May to September 2003, a total of 73 eyes of 73 patients with diabetes mellitus were examined using the SNU computerized color vision test and optical coherence tomography (OCT). Color deficiency was quantified as the total error score o...

PURPOSE To describe morphological features of the macula in patients with retinopathy of prematurity. METHODS Twelve premature babies with retinopathy of prematurity grades I, II and III underwent dilated fundus examination and optical coherence tomography evaluation. RESULTS In all thirteen eyes of the twelve premature patients optical coherence tomography revealed a condensed retinal pigm...

PURPOSE To investigate the long-term effect of macular hole surgery, foveal structure and the thickness of retinal layers were analyzed with spectral-domain optical coherence tomography (SD-OCT). The long-term postoperative course of macular thickness and best-corrected visual acuity (BCVA) were followed. METHODS In a retrospective cohort study, SD-OCT scans were obtained from the horizontal ...

BACKGROUND The purpose of this study was to compare the safety and efficacy of combined vitrectomy, intravitreal triamcinolone acetonide (IVTA), and bevacizumab injection with that of IVTA and bevacizumab injection and subsequent macular grid laser photocoagulation for the treatment of intractable diffuse diabetic macular edema. METHODS This randomized controlled clinical trial was performed ...

AIM To provide the normative data of macular and retinal nerve fiber layer (RNFL) thickness in Indians using spectral domain OCT (Spectralis OCT, Heidelberg Engineering, Germany) and to evaluate the effects of age, gender, and refraction on these parameters. DESIGN Observational, cross-sectional study. MATERIALS AND METHODS The eyes of 105 healthy patients aged between 20-75 years, with no ...

Foveal and parafoveal increment thresholds were measured for 50 observers (12-88 years of age) under conditions that isolated retinal mechanisms dominated by short- (S-), middle- (M-), or long- (L-) wave-sensitive cones. Thresholds were obtained on the plateau of the threshold-versus-intensity function of each isolated mechanism and were referred to the retina by using individual measurements o...
