 for complicated Retinal Detachment (R.D). Materials and Methods: The study was done in Ain Shames University, Faculty of Medicine, Ophthalmology department in the period between Feb. 2013 and Oct. 2014.It is a prospective study included 80 patients underwent conventional vitrectomy for different vitreoretinal diseases, In all patients silicone oil will be removed after surgery from 3-14(Average 8.5 months) months with follow- up after silicone oil removal from 1-10months (average 5.5months). Persistent IOP rise will be defined by IOP more than 21mmHg which persists after silicone oil removal for 6 weeks Incidence of persistent IOP rise will be estimated, together with risk factor and cause in each case. Results: The incidence of glaucoma after silicone oil removal was found to be 42.5% ;46 patients with normal IOP and 34 patients with high IOP and the average IOP in normal patients varying from 9 mmHg to 22 mmHg (average 15.5mmHg) and in glaucomatous patients was 26 mmHg to 50 mmHg (38mmHg). In the glaucomatous patients the risk factors were found to be: Long duration of RD before surgery in 12 patients (15%), Diabetes in 10 patients (12.5%), Long duration of silicone oil(more than 6 months) in 4 patients (5%), Trauma in 2 patients (2.5%), Aphakia in 2 patients (2.5%), Previous glaucoma in2 patients (2.5%), High myopia in1 patient (12.5.%), Multiple surgeries in 1 patient (1.25%).Examination of the anterior chamber angle using gonioscopy revealed narrow angle (grade 2) in 46patient(57.5%) all of them had normal IOP, the other group of high IOP(34 patients) showed very narrow angel (grade 1) in 12 patients (15%), closed angle (grade 0)in 8 patients(10%), Peripheral Anterior Synechial (PAS) in 14 patients (17.5%). Conclusion: Persistent glaucoma after silicone oil removal is not uncommon occurrence after silicone oil removal. The underlying mechanism may often be multifactorial in nature. Various risk factors also may be present, and so long follow for these patients is recommended to evaluate the proper treatment.&picture=http://www.aascit.org/aascit/decorators/img/journal/906.jpg)

Purpose: To evaluate the incidence, risk factors and causes of persistent glaucoma after silicone oil removal in patients underwent conventional pars plana vitrectomy (PPV) for complicated Retinal Detachment (R.D). Materials and Methods: The study was done in Ain Shames University, Faculty of Medicine, Ophthalmology department in the period between Feb. 2013 and Oct. 2014.It is a prospective study included 80 patients underwent conventional vitrectomy for different vitreoretinal diseases, In all patients silicone oil will be removed after surgery from 3-14(Average 8.5 months) months with follow- up after silicone oil removal from 1-10months (average 5.5months). Persistent IOP rise will be defined by IOP more than 21mmHg which persists after silicone oil removal for 6 weeks Incidence of persistent IOP rise will be estimated, together with risk factor and cause in each case.
