AIM To assess the distribution and causes of corneal blindness in a population in southern India. METHODS A total of 11 786 people of all ages from 94 clusters representative of the population of the Indian state of Andhra Pradesh were sampled using a stratified, random, cluster, systematic sampling strategy. These participants underwent a detailed interview and eye examination including meas...

PURPOSE To investigate the therapeutic effects of mineral oil (MO) and hyaluronic acid (HA) mixture eye drops on the tear film and ocular surface in a mouse model of experimental dry eye (EDE). METHODS Eye drops consisting of 0.1% HA alone or mixed with 0.1%, 0.5%, or 5.0% MO were applied to desiccating stress-induced murine dry eyes. Tear volume, corneal irregularity score, tear film break-u...

Corneal blindness is considered to be a serious public health problem worldwide. It is estimated that 1.2–2 million cases of corneal blindness occur globally in a year and 90% of them are from developing countries (Chirambo et al., 1986; Whitcher et al., 1997). A survey by the Government of India estimates that corneal lesions are responsible for significant blindness cases (National Survery on...

Corneal diseases constitute the second leading cause of vision loss and affect more than 10 million people globally. As there is a severe shortage of fresh donated corneas and an unknown risk of immune rejection with traditional heterografts, it is very important and urgent to construct a corneal equivalent to replace pathologic corneal tissue. Corneal tissue engineering has emerged as a practi...

PURPOSE Corneal haze is a well-known pathology associated with decreased corneal transparency and increased ocular scattering. Clinically, haze is typically estimated as the amount of backscattered light observed in a slit lamp examination while the small angle forward scattering cannot be directly observed. It was the purpose of this study to demonstrate a single-pass technique to objectively ...

PURPOSE Because of its unique characteristics, the cornea has been widely used for blood and lymphatic vessel research. However, whether limbal or corneal vessels are evenly distributed under normal or inflamed conditions has never been studied. The purpose of this study was to investigate this question and to examine whether and how the distribution patterns change during corneal inflammatory ...

PURPOSE To study the intraocular pressure (IOP), the corneal thickness and the corneal curvature distribution in a normal population. To investigate the relation between these variables, and to determine if the IOP and the paquimetry will be modified by the refractive error and age. METHODS A population of 273 subjects, 545 eyes, without ocular pathology was selected. The refractive error, th...

BACKGROUND High volume cataract surgery is practised in many eye centres. OBJECTIVE To investigate whether routine high volume cataract surgery can be performed without compromising the quality of surgery. MATERIALS AND METHODS A retrospective interventional study was carried out at a high volume eye care centre including 368 subjects with cataract operated within 5 randomly selected theatr...

PURPOSE To characterize the osmoprotective properties of L-carnitine on human corneal epithelial cell volume and apoptosis during hyperosmotic stress. METHODS Human corneal limbal epithelial (HCLE) cells were exposed to culture medium at 300 mOsm (isotonic) or 500 mOsm (hyperosmotic) with or without L-carnitine (10 mM). Induction of apoptosis was detected by quantifying the proteolytic activi...
