Abstract: Background:
Intraocular Pressure (IOP) elevation
after uncomplicated Pars Plana Vitrectomy (PPV) is a common finding in
postoperative period. The elevation of IOP is due to several factors such as
viscoelastic residue, the use of silicon oil or an expanding gas tamponed,
bleeding, a pupillary block, trabeculitis, and ciliary body oedema or a
response to topical corticosteroid treatment. Medical treatment will reduce the
IOP in most cases, however persistent glaucoma may occur as well. Aim: Is to explore the
incidence and significant factors of changes in intraocular pressure
(IOP) and persistent IOP elevation (PIOPE) in one year follow-up of patients
who underwent uncomplicated pars plana vitrectomy (PPV(. Method: An observation a retrospective study of
total 80 patients (80 eyes) who underwent PPV in ARRASEN Medical Centre due to
the presence of vitreomacular traction syndrome, persistent vitreous
hemorrhage, and Rhegmatogenous Retinal detachment (RRD) from January 2021 to
December 2021 was included in the study). Data will be
collected from ARRASEN medical recorder through pre-tested questionnaire
includes demographic and clinical characteristics and outcomes. The ethical
permission obtained from the Libyan Board Ethical Committee. Result: 80 patients
underwent PPV with mean age group (56.60 ±11.92), were 41(51.2%) males and 39
(48.8%) females. Reported 58 (72.5%) patients
had normal IOP and 22 (27.5%) patients had high IOP postoperative
immediately. Mean preoperative IOP was 13.78±2.585
mmHg, while sustain IOP postoperative in vitrectomized eye one month, after 3th
months, 6th months, and 12th months
(16.21±5.878mmHg; 15.73±3.98; 15.57±5.786; 15.57±5.786) respectively, with
p-value <0.05. SIOP was detected in vitrectomized eye and fellow eye within
the period of follow up but it was highly significant in vitrectomized eye. Conclusion: Incidence of persistent high IOP post PPV is 27% which is apparently high within Libyan patients with classical risk factors that may encourage to search for other causes. |
