Abstract

Purpose : To investigate incidence of Blepharoptosis after Trabeculectomy, Phaco-trabeculectomy and Ahmed
Glaucoma valve (AGV) and compare it with phacoemulsification

Methods : In this prospective case control study, 102 glaucomatous eyes as a case group and 28 nonglaucomatous
eyes (with uneventful phaco surgey) as a control group were included. Glaucoma surgeries were
Trabeculectomy (41 eyes; 40%), Phaco-trabeculectomy (34 eyes; 33%) and AGV (27 eyes; 27%). MRD1 (The
distance between upper eyelid and central corneal reflex) was measured before surgery and 1, 3 and 6 months
after the surgery. Ptosis was defined as a MRD1 difference (ΔMRD1) more than 2mm at the end of month 6. P value <5% was
considered as significant.The correlation among ΔMRD and clinical factors such as age, gender , type of surgeries, type of anesthesia, duration of surgery ,laterality ,surgeons( attending ,fellowships and residents) were analyzed.

Results : Mean age of the patients was 57.93±16.23 and 60.8% were male. Mean preoperative MRD1 was
2.97±0.96 and 3.15±1.11 in control and case group, respectively. Mean post-operative MRD1 at the end of month 6 was 2.78±1.18 in control group (Paired t-test, p=0.30), while it was 2.57±1.21 in glaucomatous patients (Paired t-test, p<0.0001). Overall, in 5.5% after phacoemulsification and 13.7% after glaucoma surgeries ptosis was observed postoperatively. Ptosis occurred in 13.5%, 17.2% and 20% of eyes following Trabeculectomy, Phacotrabeculectomy and AGV, respectively. However, there was no significant difference in the incidence of ptosis considering type of glaucoma surgery (Kruskal-Wallis; p=0.784).There was no statistically significant relationship between age, laterality, duration,surgeon, type of anesthesia and the rate of ptosis.Only Male gender significantly associated with post op ptosis (17% vs.2.5%)

Conclusions : Ptosis occured in considerable number of patients after Trabeculectomy, Phaco trabeculectomy and
AGV. However, there was no noticeable difference between different types of glaucoma surgery.
