    1. SD-OCT Imaging of Idiopathic Macular Holes With Spontaneous Closure

      SD-OCT Imaging of Idiopathic Macular Holes With Spontaneous Closure

      Please wait Close Window Spectral-domain optical coherence tomography serial changes in three cases of spontaneous closure of idiopathic macular hole at stages II, III, and IV are described. Initial and serial spectral-domain optical coherence tomography images document the progressive closure. Macular holes apparently resolved spontaneously through two different mechanisms: posterior hyaloid detachment in case 1 and a contraction of epiretinal macular membrane in cases 2 and 3. The spontaneous closure of idiopathic full-thickness macular holes may occur in any stage of idiopathic macular hole; the small size of the hole is a common feature in all cases of spontaneous closure ...

    2. Spectral-Domain Optical Coherence Tomography in Irvine-Gass Syndrome

      Spectral-Domain Optical Coherence Tomography in Irvine-Gass Syndrome
      Purpose: To report longitudinal evaluation of morphology and function, by spectral-domain optical coherence tomography and Early Treatment Diabetic Retinopathy Study visual acuity, respectively, in patients with cystoid macular edema after cataract surgery (Irvine-Gass syndrome). Methods: Fifteen eyes (15 patients) with a diagnosis of cystoid macular edema related to Irvine-Gass syndrome underwent ocular ophthalmologic examinations including Early Treatment Diabetic Retinopathy Study visual acuity and macular morphology assessment by spectral-domain optical coherence tomography. An observational period of 3 months after surgery was considered before starting therapy with oral acetazolamide and topical indomethacin. Patients' eyes were tested at baseline and at 3, 6 ...

    3. A morpho-functional study of amblyopic eyes with the use of optical coherence tomography and microperimetry

      A morpho-functional study of amblyopic eyes with the use of optical coherence tomography and microperimetry

      Purpose: To determine whether retinal nerve fiber layer thickness (RNFLT), macular thickness, foveal volume, macular sensitivity, and fixation in patients with amblyopia differ between the amblyopic eye and the fellow eye.Methods: Optical coherence tomography (OCT) and microperimetry (MP-1) were used to evaluate patients with unilateral amblyopia. Patients were divided into 2 groups, those with strabismic amblyopia and those with refractive amblyopia. OCT maps were used to calculate foveal volume, macular thickness, and RNFLT; MP-1 was used to determine macular sensitivity and fixation.Results: A total of 30 patients were included (13 males; mean age 19.7 years [range, 10-38 ...

    4. Morphologic Differences, According To Etiology, in Pigment Epithelial Detachments By Means of En Face Optical Coherence Tomography

      Morphologic Differences, According To Etiology, in Pigment Epithelial Detachments By Means of En Face Optical Coherence Tomography

      Purpose: To assess morphologic differences in pigment epithelial detachment (PED) with en face optical coherence tomography in central serous chorioretinopathy (CSC) and age-related macular degeneration (AMD). Methods: We recruited 30 eyes of 22 patients with PED. Nine eyes had a clinical diagnosis of CSC and 21 had AMD. All patients were assessed with en face optical coherence tomography. Morphologic PED aspects were estimated on C-scans and classified according to shape, inner silhouette, content, wall aspects, wall thickness, and size. Results: Pigment epithelial detachment shape was predominantly circular (88.8%) in CSC and irregular or with multilobular features in AMD (76 ...

    5. Unilateral amblyopia: An optical coherence tomography study

      Purpose: To determine whether retinal nerve fiber layer thickness (RNFLT), macular thickness (MT), and foveal volume (FV) in patients with unilateral amblyopia differ between the amblyopic and the sound eye.Methods: A Humphrey-Zeiss Stratus (OCT3) with software 4.0.3.1 was used to evaluate 40 patients (17 male, 23 female; mean age, 15.2 years; range, 5–56 years) with unilateral amblyopia. Patients were divided into 2 groups: 20 strabismic and 20 anisometropic. Maps of macular thickness and RNFL thickness (3.46) created by the use of optical coherence tomography were applied to calculate FV and MT and RNFLT ...

    7. The role of OCT in glaucoma management

      Clinical examination of the optic nerve and achromatic automated perimetry is the gold standard for the management of glaucoma. However, there is an increasing need for an objective evaluation of the optic nerve structure, particularly for preperimetric glaucoma. Optical coherence tomography (OCT) is a noninvasive tool that measures retinal nerve fiber layer (RNFL) thickness based on its optical properties. Computer image processing algorithms estimate NFL thickness from circumpapillary OCT images that are acquired in cylindrical sections surrounding the optic disc. Average values of NFL thickness can be calculated in the four quadrants or the 12 o’clock position sectors around ...

    8. Structure–function relationship in ocular hypertension and glaucoma: interindividual and interocular analysis by OCT and pattern ERG

      Abstract Background  Pattern electroretinogram (PERG) and optical coherence tomography (OCT) represent objective probes to investigate respectively the function of retinal ganglion cells and their structure as retinal nerve fiber layer (RNFL) thickness. We examined interindividual (II) correlations of PERG amplitude and RNFL thickness, as well as correlations between interocular (IO) differences in both measures, in ocular hypertension (OHT) and early glaucoma (EG) patients. Methods  Thirty-one OHT, 34 EG (mean deviation: −1 to −6 dB) and 16 age-matched controls were examined in both eyes. Participants had clear optical media, no or moderate refractive errors and no concomitant ocular or systemic diseases ...
