The Glowport - Illuminated vitrectomy trocar cannulas.

The use of small-gauge trocar cannulas during transconjunctival sutureless pars plana vitrectomy (PPV) facilitates the smooth transition of instruments into the posterior segment and reduces trauma. However, room lighting is routinely dimmed during PPV, thereby making cannula visualization difficult and hence compromising efficient instrument exchange. We report the use of a frugal, fluorescent "glow-in-the-dark" ring placed over vitrectomy cannulas to visualize the cannula entry, thereby providing a smooth and efficient instrument exchange.

The Slitscope.

Slit lamp biomicroscope is the right hand of an Ophthalmologist. Even though precise, its bulky design and complex working process are limiting constraints, making it difficult for screening at outreach camps, which are an integral part of this field for the purpose of eliminating needless blindness. The torchlight is the main tool used for screening.

Slit-lamp based intraocular lens microscope - A novel technique of rapid office-based microscopy.

The emergence of smartphone-based imaging devices has been a boon in the field of ophthalmology, especially in obtaining high-quality ocular images. They can be specialized and utilized for imaging-specific regions of the eye. Among the multitude of applications of smartphone-based imaging, one of the upcoming major use is to image the microbiological world.

Innovative intra-operative rapid detection test for visualisation of mucor.

In this manuscript, we report a rapid intra-operative detection test for visualisation of mucor, with the use of the Smartphone-based intraocular lens microscope (IOLSCOPE). IOLSCOPE helps not only in detecting tissue affected by mucor, but also makes sure that the surgeon does not leave any fungus behind; similar to the principles employed by a 'Frozen section' in conventional general surgery. In the technique proposed by us, we have used an undigested tissue sample, to quickly diagnose mucor, intra-operatively.

Smartphone-based intraocular lens microscope.

Microscopes play an important role in the diagnosis of microorganisms and pathological lesions in ophthalmology guiding us to the appropriate management. The current trend of collecting samples and examination is mostly laboratory-based which consume time, labor, and are costly. Smartphones are being used in different fields of ophthalmology with great ubiquity.

Antidiabetic property of Aerva lanata (L.) Juss. ex Schult. is mediated by inhibition of alpha glucosidase, protein glycation and stimulation of adipogenesis.

Background: Diabetes is the leading cause of morbidity and mortality, with a number currently diagnosed as high as 371 million. Plant-based therapy could be an ideal choice because of fewer side-effects and wider acceptability. Hence, the antihyperglycemic potential of Aerva lanata, a herb prescribed for diabetes in Ayurveda was evaluated to elucidate its possible mechanism of action.

An in vitro study reveals nutraceutical properties of Ananas comosus (L.) Merr. var. Mauritius fruit residue beneficial to diabetes.

Background: Rapid urbanisation and nutritional transition is fuelling the increased global incidence of type 2 diabetes. Pineapple fruit residue was explored for its nutraceutical properties as an alternative or adjunct to currently available treatment regime. Ethyl acetate and methanolic extracts of pineapple fruit residue were evaluated for anti-diabetic activity in cell free and cell based systems.

The Madurai Intraocular Lens Study. II: Clinical outcomes.

Purpose: To evaluate the safety and efficacy of extracapsular cataract extraction with posterior chamber intraocular lens (ECCE/PC-IOL) compared with intracapsular cataract extraction with aphakic glasses (ICCE-AG).

Methods: In a nonmasked randomized controlled clinical trial, 3,400 bilaterally vision-impaired patients aged 40 to 75 years with operable cataract were randomly assigned to receive either ICCE-AG or ECCE/PC-IOL at the Aravind Eye Hospital in India. The surgery was performed by one of four study surgeons.
