Acute primary angle closure in a patient with high myopia: a case report.

Primary angle closure in a high myopic patient is rare. Here is presented a report of one such patient who presented with acute primary angle closure in one eye. Conservative management followed by laser iridotomy was effective in the treatment of this patient.

Hydatid cyst of orbit.

A 40-year-old woman presented with protrusion and diminution of vision of left eye for 3 months. CT scan of orbit revealed an intra-orbital cystic space occupying lesion. Exenteration of the left orbit was done and histopathological examination of the cystic mass proved it to be a case of hydatid cyst.

Orbital and para-orbital tumours--a 10 years retrospective study.

A total number of 631 cases of orbital and para-orbital tumours causing proptosis was analysed in a retrospective way in relation to age, anatomic location, histological and clinical profile. CT-scan was considered as the primary modality of investigation as it correctly delineates the extent of the tumour, integrity of bony structures and intracranial spread. Different modalities of surgery like lateral orbitotomy, medial orbitotomy, lateral rhinotomy and endoscopic excision, etc, had been performed depending upon the anatomical locations.

A study of sleeping disorders in blind patients.

An internal 24-hour biological clock working in tandem with external environmental cues like bright light regulates our daily rhythms specially sleep-wake cycle. In a blind individual, due to absence of external cue endogenous rhythm may take upper hand and free running of sleep-wake cycle starts without any synchronicity with day-night cycle, creating ground for sleep disorders. To evaluate the frequency of sleep disorders, 65 blind individuals without any comorbid medical or surgical problem were interviewed according to the criteria of Diagnostic and Statistical Manual of Mental Disorder-IV (DSM-IV).

Nosocomial ocular infection--a prospective study.
