AIM To evaluate the role of glycosylated hemoglobin (HbA1c) on the occurrence of sight-threatening diabetic retinopathy (STDR) in urban Chennai, Tamil Nadu, India. METHODS A total of 5999 individuals were enumerated from the Chennai metropolis. Of these, 1414 subjects with diabetes were included for data analysis in the study. STDR or non-STDR groups were(More)
AIM To investigate the occurrence of neuronal damage, as the earliest change occurring, before the clinical evidence of diabetic retinopathy. METHODS 70 eyes of subjects with type 2 diabetes mellitus and with no evidence of diabetic retinopathy (cases) and 40 eyes of subjects with no diabetes mellitus (controls) were studied using spectral-domain OCT and(More)
Retrospective clinical and histopathological review of eight silicone oil-filled enucleated eyeballs using light microscopy was carried out in our department of ocular pathology during a period of six years. In all cases, silicone oil vacuoles, both free and incorporated within macrophages were seen in all the retinal layers. Silicone oil vacuoles were seen(More)
PURPOSE To elucidate changes in the neurosensory retina in the macular area, using spectral domain OCT and correlate with functional loss on fundus-related microperimetry, in patients with diabetes and no diabetic retinopathy compared with age-matched healthy volunteers. METHODS This was a prospective study enrolling 39 patients in each group. All(More)
BACKGROUND While lens-sacrificing vitrectomy is the standard approach to manage Stage 5 retinopathy of prematurity (ROP), scleral buckling has been used to manage some cases of Stage 4. Lens-sparing vitrectomy was popularized by Maguire and Trese in selected cases of Stage 4 disease. PURPOSE To assess the functional and visual outcomes after primary(More)
BACKGROUND Recent studies have shown significant decline in the final cure rate after miltefosine treatment in visceral leishmaniasis. This study evaluates the efficacy of miltefosine in the treatment of post kala-azar dermal leishmaniasis (PKDL) patients recruited over a period of 5 years with 18 months of follow-up. METHODOLOGY In this study 86(More)
Systemic sarcoidosis presenting as a choroidal nodule is a rare phenomenon, with limited reports in the past. We present a case of systemic sarcoidosis in a young adult male presenting as a solitary choroidal mass. The diagnosis was made based on elevated serum lysozyme, serum angiotensin-converting enzyme, negative Mantoux, and computed tomography (CT)(More)
Nested polymerase chain reaction (nPCR) was performed on enucleated eyeball for detection of Mycobacterium tuberculosis (M. tb) genome in a patient with Eales’ disease. PCR analysis in all previous studies has been done mainly using aqueous, vitreous and epiretinal membranes from these patients. Paraffin wax embedded tissue section of the enucleated eyeball(More)
We report a immunohistochemical study of expression of VEGF and PEDF in Eales' disease. An enucleated eye from a patient with Eales' disease and an age and sex-matched donor eyeball were subjected to immunohistochemical and histopathological analysis to study the expression of VEGF and PEDF in the retinal region. Strong positive anti-VEGF immunostaining was(More)
