Abstract Details

Purpose:

Pseudoexfoliation syndrome is defined as degenerative fibrillopathy related to age and whose etiopathogenesis is still unknown. It is a multiorgan disease due to a multifactorial disorder of the elastic fiber structure. The diagnosis of pseudoexfoliation syndrome is of paramount importance as this disease is a major risk factor for complications during cataract surgery because of the increased weakness of the zonular apparatus and limited pupil dilation. The purpose of this study is to analyse the epidemiological and clinical features of capsular pseudoexfoliation syndrome and to determine complications of cataract surgery in eyes with capsular pseudoexfoliation syndrome.

Setting:

A retrospective study was conducted on 84 cases with capsular pseudoexfoliation (PEC) syndrome among  790 patients scheduled for cataract surgery in the Department of ophthalmology B at Ibn Sina Hospital between September 2018 and August 2019.

Methods:

All patients were examined with slit lamp before and after pharmacologic mydriasis. The diagnosis of capsular pseudoexfoliation syndrome was clinical, defined by the deposition of white dandruff-like material, called pseudo-exfoliative material on the anterior capsule of the crystalline lens after dilatation. We analyzed Demographic parameters (age, sex, ethnicity, medical and ophthalmologic history), ophthalmological examination features (visual acuity, pupil dilatation, uni / bilateral, intraocular pressure) before surgery, and surgical complications of patients with capsular pseudoexfoliation syndrome scheduled for cataract surgery by phacoemulsification or extracapsular extraction.

Results:

PEC syndrome is reported in 84 patients operated for cataract. The average age is 69 years. 43 patients were diabetic and 52 were hypertensive. The intraocular pressure was high (17.4 mmHg), this elevation is due to trabecular blockage by exfoliative material. Poor pupillary dilatation was observed in 30cases. 2 cases of lens subluxation was noted. Phacoemulsification was performed in 51 eyes, extracapsular extraction in 31 eyes and intracapsular extraction in lens subluxation cases. Iris retractors were used in 8 cases otherwise viscoelastic devices or intracamerular adrenaline use were sufficient. Surgical complications were zonular disinsertion and capsular rupture with vitreous loss.

Conclusions:

This retrospective study presents the clinical and epidemiological characteristics of 84 eyes with capsular pseudoexfoliation syndrome scheduled for cataract surgery. PEC syndrome should be routinely investigated in the preoperative assessment of cataract and should be suspected in the presence of poor pupillary dilatation. The presence of PEC syndrome is a risk factor for open-angle primary glaucoma and it exposes to surgical complications during cataract surgery, regardless of the technique used.
