Changes in the thickness of the macular ganglion cell complex and retinal nerve fiber layer over time after surgery in a case of juvenile glaucoma

چکیده
Purpose To report longitudinal changes over time after surgery in the topography of the optic disc, thickness of the circum papillary retinal nerve fiber layer (c-RNFL), and thickness of the macular ganglion cell complex (m-GCC) in a case of juvenile open angle glaucoma. Observations Case report based on one patient. After significant edema of the optic disc for 2 months, the cup depth and cup volume measured by Heidelberg retina tomograph images showed reversal, which lasted for 3 years. The c-RNFL thickness and m-GCC thickness measured by spectral domain optical coherence tomography first increased for a week and then continued to decrease until 6 months after operation. These two parameters reached a plateau after 3 years. The mean deviation of global visual field indices of the Humphrey visual field revealed a very mild reduction for this 3 year period. Conclusions and importance In juvenile onset glaucoma, changes in c-RNFL thickness and m-GCC thickness after operation were not consistent with changes in optic disc cupping. Changes in the thicknesses of the c-RNFL or m-GCC, rather than changes in the optic disc changes, may be good surrogate measures to confirm the effectiveness of glaucoma surgery.

Introduction: Alzheimer disease (AD) is the most common form of dementia worldwide. The modalities to diagnose AD are generally expensive and limited. Both the central nervous system (CNS) and the retina are derived from the cranial neural crest; therefore, changes in retinal layers may reflect changes in the CNS tissue. Optical coherence tomography (OCT) machine can show delicate retinal layer...
متن کاملClinical Applications of Optical Coherence Tomography in Ophthalmology
Assessment of the peripapillary nerve fiber layer and macular thickness can be determined in ophthalmology using optical coherence tomography (OCT). Decreased nerve fiber layer thickness and macular ganglion cell thickness in optic nerve ischemia have been correlated with visual field loss. OCT allows deep optic nerve head evaluation which helps understand pathophysiology of diseases. Furtherm...
متن کاملComparative analysis of macular and peripapillary retinal nerve fiber layer thickness in normal, glaucoma suspect and glaucomatous eyes by optical coherence tomography.
INTRODUCTION Peripapillary retinal nerve fiber layer (RNFL) thickness analysis is a subjective method of analysis of glaucomatous damage. As almost 50% of retinal ganglion cells are located in the macula, assessment of macular thickness can be an alternative method for diagnosis of glaucoma. OBJECTIVES To evaluate the changes in macular and retinal nerve fiber layer thickness in controls, gla...

Purpose. We evaluated the association between optic nerve head (ONH) microcirculation and macular ganglion cell complex (mGCC) thickness in patients with untreated normal tension glaucoma (NTG) and a hemifield defect. Methods. The medical records of 47 patients with untreated NTG were retrospectively reviewed. Laser speckle flowgraphy was used to obtain mean blur rate (MBR), a relative measure ...
