BACKGROUNDGlaucoma is the second leading cause of blindness worldwide. Intraocular Pressure (IOP) is the only known modifiable risk factor that has been shown to delay progression in both ocular hypertension and glaucoma patients. Clinical measurement of IOP has undergone several technical advances from the initial digital tension measurements, through indentation tonometry, to applanation tonometry and non-contact tonometry. This study was done to compare the intraocular pressure (IOP) measurements with Non Contact Tonometry (NCT) and Goldmann Applanation tonometry (GAT) and to compare NCT IOP and GAT IOP among various central corneal thickness (CCT) groups.

BACKGROUNDOne of the most common ocular surgery, i.e. cataract surgery is today highly efficient and has a predictable outcome. Still, eyelid malpositions can occur after cataract surgery. Of these, blepharoptosis of upper eyelid occurs and sometimes persists even after few months of surgery. This occurrence depends on the surgical technique and method of ocular anaesthesia given.The aim of the study is to know the incidence and probability of developing postoperative persistent ptosis (>12 weeks) after different surgical techniques and anaesthetic methods.

BACKGROUNDRefractive errors are considered to be a preventable cause of blindness, leading to visual disabilities in children. As per WHO Vision 2020 initiative high priority is given for correction of refractive error as it is placed within the category of "childhood blindness". Uncorrected refractive error can result in amblyopia or strabismus. The risk of developing amblyopia occurs if the children are not screened early for refractive errors and corrected on time. Most of the children with uncorrected refractive errors are asymptomatic and screening helps in early detection and timely intervention to avoid complications. Thus, the purpose of this study was to estimate the frequency and pattern of refractive errors, and to analyse associations between refractive error and different types of strabismus and amblyopia in paediatric age group <12 years who attended our Ophthalmology OPD at Govt. Stanley Medical College Hospital located in North Chennai.

BACKGROUNDManual Small Incision Cataract Surgery (MSICS) is a well-known technique of cataract surgery owing to its advantage of a selfsealing suture less incision with least surgically induced astigmatism at a low cost. It is a safe, simple, consistent, stable and cost-effective technique with various modifications that involve site, size, type of incision and method of nucleus delivery. One such modification is Temporal Incision MSICS, where the cataract surgery is done by a temporal approach, which is equally good compared to the superior incision. This study was done retrospectively to analyse the visual outcome of patients operated by Manual SICS -Temporal Approach, using the WHO criteria and to establish its efficacy as a good surgical technique.
