PURPOSE To evaluate the safety and efficacy of corneal collagen cross-linking (CXL) in the treatment of keratoconus in pediatric patients. METHODS Epithelium-off CXL using the standard protocol was performed in 15 eyes from 15 patients (age range: 10 to 15 years) with moderate keratoconus in 1 eye and advanced disease in the fellow eye. Principal outcomes(More)
Xeroderma pigmentosum (XP) is a rare genetic disease characterised by defective DNA repair leading to clinical and cellular hypersensitivity to ultraviolet radiation. The oculocutaneous features of 10 patients with XP were studied retrospectively. General features included parental consanguinity (40%), familiarity (60%), onset of symptoms in first 2 years(More)
Ninety-one consecutive cases of proven oculomycosis were studied in relation to clinical features and epidemiological parameters. Mycotic corneal ulcers formed the major group (76%), followed by endophthalmitis (20%). Aspergillus was the common causative fungus (36%) in keratomycosis followed by Penicillium species (29%). Fusarium keratomycosis was not as(More)
A 32-year-old lady presented with bilateral painful proptosis and left infranuclear facial palsy. She was mildly anemic. Ocular examination revealed a firm non-tender mass in the super lateral quadrant of both orbits. Fine-needle aspiration cytology from the orbital mass showed the presence of lymphoplasmacytoid cells. Bone marrow aspiration also showed the(More)
Related adhesion focal tyrosine kinase (RAFTK) (also known as PYK2) is a cytoplasmic tyrosine kinase related to the focal adhesion kinase (FAK) p125(FAK). RAFTK is rapidly phosphorylated on tyrosine residues in response to various stimuli, such as tumor necrosis factor-alpha, changes in osmolarity, elevation in intracellular calcium concentration,(More)
The lactate dehydrogenase (LDH) levels were measured in the aqueous humor and serum of 16 patients (20 eyes) with retinoblastoma. The enzyme activity in the aqueous humor and serum did not show any correlation with each other. Age of presentation, age of enucleation, sex and disease duration had no correlation with the enzyme level either in the serum or(More)
PURPOSE To compare visual outcome, higher-order aberrations, and corneal asphericity (Q value) between wavefront-guided and aspheric LASIK for myopia and myopic astigmatism. METHODS Forty patients were randomly selected to receive wavefront-guided LASIK (wavefront-guided group) or aspheric LASIK (aspheric group) (40 eyes of 20 patients in each group)(More)
