Abstract

Purpose

To investigate the possibility of blepharoptosis as a complication after panretinal photocoagulation using oph-thalmoscopic 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 decre-ment 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.

The illustration shows the relation between the eye-lid and contact ophthalmoscopic lens. When the contact oph-thalmoscopic lens is fitted to the eyes, the lower part of the up-per eyelid is bent against the patient’s eyes and the dehiscence or disinsertion at the insertion part of levatoraponeurosis could occur (arrow).
