Visual field changes in glaucoma patients after blepharoptosis surgery.

Area of Science:

• Ophthalmology
• Glaucoma Research
• Surgical Outcomes

Background:

• Blepharoptosis, or drooping eyelids, can potentially obstruct vision.
• Accurate visual field testing is crucial for managing glaucoma.
• The impact of blepharoptosis surgery on visual field parameters in glaucoma patients requires investigation.

Purpose of the Study:

• To evaluate the effect of blepharoptosis surgery on visual field test parameters in patients diagnosed with glaucoma.
• To compare pre-operative and post-operative visual field data, including mean deviation (MD), pattern standard deviation (PSD), and total deviation (TD).

Main Methods:

• A cohort of 14 glaucoma patients (23 eyes) underwent blepharoptosis surgery.
• Pre- and post-operative data were collected for margin reflex distance-1 (MRD-1), best-corrected visual acuity (BCVA), intraocular pressure (IOP), and Humphrey visual field test parameters (MD, PSD, TD).
• Statistical analysis was performed to compare pre- and post-operative values.

Main Results:

• Blepharoptosis surgery led to a significant improvement in MRD-1 (p < 0.001).
• A significant improvement was observed in the superior visual field's total deviation (TD) (p = 0.044), but not in the inferior TD.
• No significant changes were noted in BCVA, IOP, MD, or PSD values post-surgery.

Conclusions:

• Blepharoptosis surgery can improve eyelid obstruction and potentially enhance superior visual field assessment in glaucoma patients.
• Pre-operative lower MD and superior TD values may predict a better surgical outcome in terms of visual field improvement.
• Blepharoptosis may act as a confounding factor in the accurate assessment of visual fields in glaucoma patients, particularly for the superior field.
