RESUMEN
A case of post-traumatic keratoconus is presented. This is an unusual variant of an uncommon disorder. Posterior keratoconus is a very rare ectatic dystrophy of the cornea. Since its first description in 1927, only a few cases have been described in the literature. Posttraumatic posterior keratoconus is a much rarer entity. We are reporting a case of posterior keratoconus caused by iron nail injury.

One hundred and fourteen eyes with congenital dacryocystitis have been studied clinically and bacteriologically. Gram positive cocci constituted the major bacterial isolates (57.9%) with streptococcus pneumoniae predominating (28.9%). The most effective antibiotic was cloxacillin with an overall efficacy of 77%. Normal conjunctival flora was sterile in majority (75%) of cases. Positive cases showed preponderance of gram positive cocci (21.6%) with staphylococcus albus (13.3%) being the major isolate. Normal nasal flora revealed diphtheroids (alone or in combination) to be the commonest bacteria (62.1%). A statistically significant correlation was not observed between the normal conjunctival or nasal flora and flora from the affected eyes.

An epidemic of acute conjunctivitis occurred in Delhi during July-September 1986. The clinical presentation in total of 350 patients were characteristic of acute haemorrhagic conjunctivitis (AHC). Bacterial cultures from conjunctival swabs were sterile in 85 out of 105 (80%) patients, virus cultures in Vero and HeLa cells were negative in 30 patients. However, conjunctival scrapes from 20/30 (66.7%) patients showed specific cytoplasmic fluorescence with enterovirus 70 (EV 70) antiserum, suggesting EV 70 to be the etiologic agent of the epidemic.
