The pupil cycle time test: age variations in normal subjects.

The pupil cycle time test: age variations in normal subjects.

Edge-light pupil cycle time.

A thin slit-lamp beam illuminating the pupil margin produces clearly visible pupil oscillations. These oscillations can be timed with a stopwatch, thus producing a measurement of the "edge-light" pupil cycle time'. The pupil cycle time is remarkably stable in various testing situations and is repeatable within about +/- 3% over extended periods of time. Expected normal distribution and 95% con...

A comparative study of Edge light pupil cycle time in type-II diabetes mellitus patients and normal subjects

Purpose of the study is to compare the pupil cycle time(PCT) of patients with type-II diabetes and healthy control subjects.To analyse the effect of different variables like age, sex, blood sugar,diabetes duration on PCT.MethodsThe study was conducted on known type-II diabetes patients attending retina clinic and non diabetic patients attending Eye OPD of Regional institute of medical sciences,...

Pupil cycle time and early autonomic involvement in ocular leprosy.

Ocular complications of leprosy patients often develop insidiously and with few if any symptoms. This study involves measurement of the pupil cycle time (PCT) to evaluate the autonomic nerve system of the iris to determine the presence of subclinical intraocular involvement. The study included 19 lepromatous (LL), 19 borderline lepromatous (BL), and five borderline tuberculoid (BT) leprosy pati...
