NCT07621952

Brief Summary

This observational cross-sectional study aims to evaluate meibomian gland loss and dry eye symptoms in patients using unilateral ocular prostheses. The study compares the prosthetic eye with the contralateral healthy eye using the DEQ-5 questionnaire and meibography obtained with the Oculus Keratograph 5M. Additional ocular surface parameters, including conjunctival hyperemia and tear meniscus height, are also evaluated. The objective is to determine whether ocular prosthesis wear is associated with morphological changes in the meibomian glands and increased dry eye symptoms.

Outcome Measures

Primary Outcomes (1)

  • Meibomian Gland Loss

    Meibomian gland loss in the upper eyelid assessed by meibography using the Oculus Keratograph 5M and compared between prosthetic eyes and contralateral healthy eyes.

    At baseline

Secondary Outcomes (2)

  • Dry Eye Symptoms

    At baseline

  • Conjunctival Hyperemia

    At baseline

Study Arms (2)

Prosthetic Eye

Eyes with ocular prostheses in patients with unilateral anophthalmic socket. Meibomian gland morphology, dry eye symptoms, conjunctival hyperemia, and tear meniscus height were evaluated.

Diagnostic Test: Oculus Keratograph 5M

Healthy Contralateral Eye

Contralateral healthy eyes of the same patients used as controls for comparison of ocular surface and meibomian gland findings.

Diagnostic Test: Oculus Keratograph 5M

Interventions

Oculus Keratograph 5MDIAGNOSTIC_TEST

Dry Eye Questionnaire-5 used to assess dry eye symptoms in prosthetic and healthy eyes.
