Retinoblastoma (RB), a malignant tumour of the eye arising from developing retina, is the most frequent primary intraocular malignancy of childhood. Its primary management with chemotherapy involves combination regimen of etoposide, vincristine and carboplatin and intra vitreal chemotherapy using melphalan when vitreous seeds develop. Radiotherapy is another effective mode in treating RB.

Purpose: We aimed to describe a new technique and analyse the early outcomes of augmenting the canine tooth using a mandibular bone graft in an attempt to delay or retard the process of laminar resorption following the modified osteo odonto keratoprosthesis (MOOKP) procedure.
Design: This was a retrospective case series.
Patients And Methods: Eyes that underwent the bone augmentation procedure between December 2012 and February 2014 were retrospectively analysed.

Background: Epithelial cell adhesion molecule (EpCAM) is overexpressed in solid tumors and regarded as a putative cancer stem cell marker. Here, we report that employing EpCAM aptamer (EpApt) and EpCAM siRNA (SiEp) dual approach, for the targeted delivery of siRNA to EpCAM positive cancer cells, efficiently inhibits cancer cell proliferation.
Results: Targeted delivery of siRNA using polyethyleneimine is one of the efficient methods for gene delivery, and thus, we developed a novel aptamer-PEI-siRNA nanocomplex for EpCAM targeting.

Background: With the increasing number of cataract surgeries, incidence of posterior segment complications including rhegmatogenous retinal detachment (RRD) is likely to rise. Scleral buckling (SB) surgery is an effective and less expensive option. The primary advantage of non-drainage procedure is avoidance of possible complications associated with trans-choroidal drainage.

Purpose: To investigate the effect of optic neuritis (ON), ischemic optic neuropathy (ION) and compressive optic neuropathy (CON) on multifocal visual evoked potential (mfVEP) amplitudes and latencies, and to compare the parameters among three optic nerve disorders.
Materials And Methods: mfVEP was recorded for 71 eyes of controls and 48 eyes of optic nerve disorders with subgroups of optic neuritis (ON, n = 21 eyes), ischemic optic neuropathy (ION, n = 14 eyes), and compressive optic neuropathy (CON, n = 13 eyes). The size of defect in mfVEP amplitude probability plots and relative latency plots were analyzed.

The aim of our study was to isolate and characterize the properties of neurospheres and differentiated cellular progeny derived from iris and ciliary pigment epithelial (IPE and CPE) cells of human cadaveric eyes. In this study we investigated the gene expression profiles of the stem/progenitor cells and the differentiated progeny derived from IPE and CPE cells, as the changes underlying differentiation of the stem/progenitor derived from the IPE and CPE cells from human cadaveric eye are essentially unknown. The IPE and CPE cells from human cadaver eyes were cultured in the presence of mitogens to generate neurospheres (NS) and the growth characteristics were evaluated.

Plexiform neurofibromas occur in about 60% of neurofibromatosis type 1(NF-1) patients and can lead to severe morbidity by disfigurement or compression of vital structures. Moreover, these tumors can undergo malignant transformation. Both focal and localized bone abnormalities are part of the phenotypic expression of NF-1.

Anterior uveitis is the most common form of uveitis in most regions of the world. A recent study reported that 50 % of patients with anterior uveitis have a related systemic illness. The most common cause of anterior uveitis to date remains idiopathic (45-50 %), followed by HLA-B27-positive acute anterior uveitis.

Purpose: To investigate macular pigment optical density (MPOD) in patients with and without wet age-related macular degeneration (AMD) and to elucidate the association between MPOD and the risk factors for AMD in an Indian population.
Methods: Thirty-three subjects with wet AMD and 29 controls above 50 years old underwent MPOD measurement with the 'Macular Densitometer'. The subjects were also tested for their smoking history, lifetime ultraviolet (UV) exposure, dietary intake of carotenoids, and body mass index (BMI).

Purpose: To analyze the outcome (functional and anatomic) of eyes that underwent tenonplasty as the primary globe-saving procedure in severe ocular chemical injuries (grade V-VI Dua's classification).
Methods: The records of patients who underwent tenonplasty for associated scleral ischemia in severe chemical burns in our institute between October 2005 and June 2011 were analyzed retrospectively. Out of 31 eyes that underwent tenonplasty, 21 belonged to grade V and VI of Dua's classification with diffuse scleral ischemia for which a four-quadrant tenonplasty was performed and only these 21 eyes were included for further analysis.

Choroidal neovascularization (CNV) is a rare complication associated with coloboma of the choroid. We describe three cases of coloboma choroid where there was loss of vision due to CNV development at the edge of the coloboma. One was managed by photodynamic therapy alone and two were managed by a combination of reduced fluence PDT and intravitreal bevacizumab.
