Primary calcareous degeneration of the cornea is a very rare condition. Axenfeld (I9I 7) reported a bilateral case in a boy aged 8 years; a massive deposition of calcium phosphate occurred in the superficial and central strata ofthe parenchyma, slightly affecting Bowman's membrane and leaving the epithelium intact (Duke-Elder, I 965). Michail (I 935) reported a similar case which followed a slight injury but the changes were quite disproportionate to the original damage.In these three eyes the lesion started round the periphery and extended towards the centre, but Tita (1940) reported a case in which the deposits were localized.Two cases of primary calcareous degeneration of the cornea, one unilateral and the other bilateral, are presented below. Examination General and systemic examination revealed nothing abnormal. Both eyes presented an almost symmetrical and identical picture. A dense chalky-white linear-shaped opacity (about I mm. wide) with irregular margins ran along the limbus from io to 2 o'clock ( Figs I and 2).There was a clear area of 2-3 mm. between the opacity anid the limbus. From this linear opacity numerous small processes of similar nature extended vertically in an irregular manner towards the centre of the cornea but fell short of the pupillary area. The patient reported that this opacity had been present since childhood and was not increasing. There was no history of soreness or trauma, and no one in his family had suffered from a similar condition.FIGIs and 2 Right and left eyes in Case I
A 21-year-old male from Kerala, south India, who had been living in Chandigarh for the last 4 years presented with a nasal polyp in the left nasal cavity. On histopathological examination, it was found to be due to rhinosporidiosis. This disease is not uncommon in south India, but few case reports have been documented from north India. This paper presents a case report of rhinosporidiosis from the Government Medical College and Hospital, Chandigarh, and a review of literature of the disease.
