Significance of Monocular Pupillary Distance in Prescribing Glasses
Dr. Priethikka M S | Dr. Solasa Deepthi
Abstract: Purpose: The aim of this study is to measure the monocular pupillary distance and interpupillary distance in patients with refractive errors to analyze its significance while prescribing spectacles. Methods: The research was conducted at a tertiary multispecialty hospital with patients seeking treatment for refractive errors at the ophthalmology outpatient department. Monocular Pupillary Distance and Inter Pupillary Distance were measured using a pupillometer and assessed in each patient. A total of 500 patients were included in the study, excluding those with ocular and neurological conditions unrelated to refractive errors. Results: Monocular pupillary diameter and interpupillary distance were assessed using a pupillometer in a study involving 500 patients. Among them, 250 were male and 250 were female, all of whom wore glasses. Among the males, 215 had identical Monocular Pupillary Distance (MPD) and Interpupillary Distance (IPD), while 35 exhibited differences. Among the females, 210 showed identical MPD and IPD, with 40 displaying variations. This represents approximately 15% of the total population under study. Conclusion: To conclude, both the parameters are crucial while prescribing glasses to avoid aberrations and asthenopia symptoms.
