ZyraDoc #30 - August 31, 2026

A 28-year-old man presents with a drooping left upper eyelid that has progressively worsened over three months.

Examination reveals a large, palpable, non-tender nodule measuring 8 mm within the structural tarsal plate of the upper lid.

The vertical size of his palpebral aperture is significantly reduced, and the lid margin partially covers his pupil, causing visual obscuration.

Case Summary

Clinical Focus:

A 28-year-old male presents with secondary mechanical ptosis driven by a large, chronic, non-inflammatory meibomian gland chalazion located within the structural matrix of the upper tarsal plate.

Diagnostic criteria for mechanical chalazion-induced ptosis include:

Presence of a painless, firm, non-erythematous, non-fluctuant localized lid nodule
Anatomical reduction in the size of the palpebral aperture due to tissue mass loading
Partial or complete pupillary coverage by the drooping upper eyelid margin
Higher incidence in the upper eyelid due to the increased length and number of meibomian glands

When an internal tarsal lesion is large enough to induce secondary mechanical ptosis or distort the normal cornea, definitive surgical drainage via a transconjunctival approach is the clear standard of care.
