A Prospective Study of Blepharoptosis after Panretinal Photocoagulation Using Ophthalmoscopic Contact Lens

ABSTRACT

PURPOSE: To investigate the possibility of blepharoptosis as a complication after panretinal photocoagulation using ophthalmoscopic contact lens. METHODS: We prospectively evaluated patients who were diagnosed with diabetic retinopathy and scheduled to be treated with panretinal photocoagulation. Margin reflex distance 1 (MRD1), levator function, palpebral fissure height and width, and tarsal plate height were measured at the day of photocoagulation and 3 months after treatment. RESULTS: MRD1 was decreased in 8 eyes (25.8%), levator function was decreased in 5 eyes (16.1%), and palpebral fissure height was decreased in 6 eyes (19.4%). The decrement of MRD1 and palpebral fissure height after photocoagulation were significant (p = 0.008, p = 0.031, respectively). There was a significant negative correlation between MRD1 decrement and tarsal plate height (p = 0.045). CONCLUSIONS: We identified blepharoptosis after panretinal photocoagulation using contact ophthalmoscopic lens, which was related with low tarsal plate height.
