Detaljeret beskrivelse
Loss of the eyeball and subsequent use of ocular prostheses have been associated with symptoms such as dryness, irritation, mucoid discharge, conjunctival hyperemia, and ocular discomfort. Meibomian gland dysfunction has been proposed as one of the mechanisms contributing to evaporative dry eye in anophthalmic socket patients. Chronic mechanical friction between the prosthesis and the tarsal conjunctiva, inflammation, and alterations of the ocular surface may induce glandular obstruction and atrophy.
This observational cross-sectional study evaluates morphological changes of the meibomian glands and dry eye symptoms in patients using unilateral ocular prostheses treated at the Oculoplastic Department of the Instituto de Oftalmología Fundación Conde de Valenciana, Mexico City, Mexico.
Adult patients with a history of enucleation or evisceration and at least 6 months of ocular prosthesis use are included. Each participant serves as their own control by comparing the prosthetic eye with the contralateral healthy eye.
Dry eye symptoms are assessed using the Dry Eye Questionnaire-5 (DEQ-5). Meibomian gland morphology, conjunctival hyperemia, and tear meniscus height are evaluated using the Oculus Keratograph 5M.
The primary objective is to determine the association between ocular prosthesis wear and meibomian gland loss. Secondary objectives include evaluating the association between prosthesis use and dry eye symptoms, conjunctival hyperemia, and tear meniscus alterations. The study also explores possible associations between prosthesis cleaning habits, duration of prosthesis use, and ocular surface findings.
