PRP appeared to enable biological healing of the lesion, whereas CS appeared to provide short-term, symptomatic relief but resulted in tendon degeneration.

Dr. Singh rightly points out that in this paper the transient response was obtained through the inversion of the already available frequency response (Wait, 1952). The neglect of the monopolar contribution ([Formula: see text] term) by Dr. Wait remained unnoticed, rather surprisingly, for well over two decades! The results obtained in my paper would, therefore, appear to be misleading, or more appropriately, incomplete. There are some significant factors, however, which reveal that the apparent fallacy in the presented interpretation scheme is only of a trivial nature. This is elaborated below.

Focal choroidal excavation (FCE) is defined as an area of concavity in choroid detected on optical coherence tomography. These are mostly present in macular region without evidence of accompanying scleral ectasia or posterior staphyloma. Though initially considered to be congenital, increasing number of cases have been identified in association with other choroidal pathologies such as central serous choroidopathy, choroidal neovascularisation, polypoidal choroidal vasculopathy, choroiditis, choroidal tumours. In this review article, we aim to elaborate on the morphology, pathogenesis and differential diagnosis of FCE and specifically discuss the spectrum of diseases with known association along with the impact of their treatment on FCE

In this paper a technique for computing type curves for the two-electrode resistivity soundings is presented. It is shown that the apparent resistivity due to the system can be represented by a convolution integral. Thus, it is possible to apply the principle of digital linear filtering and compute the desired type-curves. The filter function required for the purpose is found to be identical with that used to compute the EM sounding curves for the two coplanar horizontal loop system.It is further shown that from the two-electrode apparent-resistivity expression one can easily derive the apparent resistivities for other configurations. A comparison of depths of investigation for various systems reveals that the two-electrode system has greater depth of investigation than other conventional systems. This is also supported by the field example presented in the end, which illustrates the relative performance of the two-electrode system vis-a-vis the Wenner system.
