Introduction: Tamoxifen citrate is an anti-estrogen agent used in the treatment of breast carcinoma. Crystalline maculopathy is a rare complication of tamoxifen therapy. The clinical picture resembles that of idiopathic macular telangiectasia (IMT) Type 2, which is a more common clinical entity.  Objective: To report a case of crystalline maculopathy secondary to tamoxifen and highlight the importance of the medical history and investigations in differentiating it from IMT Type 2.  Case: A diabetic female with a past history of breast carcinoma treated with tamoxifen came to the hospital for a routine eye check-up. Crystalline deposits were seen in the parafoveal region in both the eyes. The spectral domain optical coherence tomography (SD-OCT) showed foveal cysts in the inner retinal layer and fundus autofluorescence (FAF) and fundus fluorescein angiography (FFA) were within normal limits.  Conclusion: While tamoxifen maculopathy is reversible on stopping the therapy, IMT needs a long-term follow-up to monitor the potential risk of loss of vision due to choroidal neovascularization, hence necessitating the distinction between these two different clinical entities.DOI: http://dx.doi.org/10.3126/nepjoph.v6i2.11713Nepal J Ophthalmol 2014; 6 (12): 227-229

Analysis of the reflex behaviour of striped muscles involves data drawn from their histological structure, and the present observations deal with the differences in microscopical and macroscopical structure of muscles of different contractile properties. Stefano Lorenzini (55) mentioned the striking difference in colour between certain muscles of the limb in the rabbit as long ago as 1678. The classic investigations of Ranvier (63, 64, 65, 66, 67, 68), however, revealed most of the present knowledge of red and pale muscle. He showed that this redness was associated with slowness of contraction, and with the genesis of tetanus at lower rates of stimulus. Moreover, these functional differences were shown to be associated with a difference in histological structure, a relatively larger amount of granular sarcoplasm and more distinct longitudinal striation in the case of red muscle. Later studies (1, 57, 43, 72, 49) revealed the occurrence of these granular and longitudinally striated fibres in muscles in many species, and also that these fibres were not always associated with redness of pigmentation (57). The histology of muscle in the higher mammalian forms has shown that both granular “sarcoplasmic” and clear “aplasmic” fibres occur side by side in the same muscle, and these two types of fibre have been homologised with the red pale muscles of the rabbit (29, 30, 43, 73, 42).

Striped Muscle

Curiously enough many of the early microscopists—Schwann for instance—recognised that the fibrils of a muscle are not simply threads of uniform thickness, like those of connective tissue: they were able to demonstrate their varicose character, even with the imperfect lenses at their command.
