Abstract Details

Purpose:

To compare the results of cataract surgery in pseudoexfoliation glaucoma with or without prior trabeculectomy .

Setting:

Department of Ophthalmology, Haydarpaşa Numune Training and Research Hospital, Istanbul, Turkey

Methods:

We undertook a retrospective analysis of 74 eyes with pseudoexfoliation glaucoma. The study group included 37 trabeculectomized pseudoexfoliation glaucoma eyes that have cataract surgery . Medically controlled 37 eyes with pseudoexfoliation glaucoma undergoing cataract surgery were selected as controls. Comparisons between study and control groups were performed for age, gender, follow up time,glaucoma diagnosis time, cataract density. Additionally visual acuity, IOP, number of glaucoma medications before cataract surgery and the last follow up were compared. Within the trabeculectomized group, effect of cataract surgery time and trabeculectomy success were determined. İntraoperative and postoperative complications of cataract surgery were analysed.

Results:

The mean age during cataract surgery was older in medically controlled group (p=0,016).There was no statically difference in gender, mean follow up time and cataract density between two groups.  Although the difference between preoperative and postoperative IOP values in  trabeculectomized group were not statically significant (p=0,091), values were statically significant in contol group (P=0,001). The comparation of the difference between preoperative and postoperative glaucoma medication numbers were statically significant (p=0,03). Between the two groups, significant differences in terms of cataract surgery complications were found only at the postoperative IOP peak in first week.

Conclusions:

In this retrospective comparative study, the mean glaucoma diagnosis time until cataract surgery was significantly higher in tabeculectomized pseudoexfoliation glaucoma patients.In terms of intraoperative cataract surgery complications, the two group were similar. There was a significant IOP decrease in medically controlled group whereas no significantly IOP change we detected in trabeculectomized group in the last follow up. IOP peak was almost 1/3rd of medically controlled group. Also uncontrolled IOP increase requiring additional glaucoma surgery were comparable in both groups.
