ABSTRACT
Fundus imaging with a fundus camera is an essential part of ophthalmic practice. A mobile phone with its in‑built camera and flash can be used to obtain fundus images of reasonable quality. The mobile phone can be used as an indirect ophthalmoscope when coupled with a condensing lens. It can be used as a direct ophthalmoscope after minimal modification, wherein the fundus can be viewed without an intervening lens in young patients with dilated pupils. Employing the ubiquitous mobile phone to obtain fundus images has the potential for mass screening, enables ophthalmologists without a fundus camera to document and share findings, is a tool for telemedicine and is rather inexpensive.
ABSTRACT
Studies on the effectiveness of age of in vitro grown seedlings on regenerative response of explants derived from them were conducted in tomato (Solanum lycopersicum L.) cv. PKM-1. The results revealed that cotyledons and hypocotyls of 10 days old seedlings were found to be superior compared to explants collected from 8, 12, 14 days old seedlings when MS medium is supplemented with BAP 1.5 mg/L + Kinetin 1.0 mg/L. These findings could be well exploited for further development of quick regenerative and transformation protocols for the tomato cv.PKM-1.
