“…It was obvious that most patients who underwent PPV were above 50 years of age 14 . Similar trends were also observed in other PPV based studies from Korea 13 , Africa 8 and USA 15 and India 9,10 . So not only the younger age group but also middle to old age patients were at risk of developing retinal detachments and pathologies.…”

“…The increased prevalence of male patients presenting at a private set up can be related to more financial resources for them, men are main bread winners of family and there is male dominant social set up in Asia and less concerns of aging ladies for their visual requirements. Such distribution of patients is also in other studies done in Africa 8 (male to female ratio 2.4:1), India (1.2:1) 9,10 , Nigeria (3.4:1) 11 , Nepal (4.3:1) 12 and Korea (2:1 ) 13 .…”

“…Some surgeons inject intravitreal Anti VEGF before PPV in every case of vitreous hemorrhage if no TRD seen on B scan, for better visual outcome but in our study, it was not practiced until neovascular component was found to be greater than fibrous component in proliferative retinopathy. Vitreous hemorrhage was top indication for PPV in studies from Nepal, Korea and India 10,12,13 .…”

Purpose: To evaluate common indications and anatomical outcomes of PPV for posterior segment ocular diseases in patients presenting at private retina clinic in Lahore Study design: Cross sectional survey Methods and materials: Over the period of three years, from 1st April 2017 to 3oth April 2020, all patients fulfilling inclusion criterion, were included in study after approval from hospital ethical committee. After taking history and detailed ocular examination, diagnosis was confirmed by B scan or OCT, Hepatitis B & C screening done. The patient age, gender, laterality of eye, lens status, macular status, type of retinal pathology, type of anesthesia, procedure done and type of vitreous tamponade if used were noted. All procedures were performed by a single surgical team and patients were followed for six months for anatomical success or any complication. Data was analyzed by SPSS 25. Results: Out of 266 total patients, 168 (63.2%) were males and 98 (36.8%) were females. Right eye was involved in 125 (47%) and left in 141 (53%). Age range was from 2 years to 83years, mean age for males was 47.30, for females 48.07 years, median age was 50 years, mean age for GA was 30.62 years and 51.71 for LA patients. The highest incidences of posterior segment ocular problems were observed in patients with age range 51 to 60 years. The commonest indication for posterior segment surgery were RRD seen in 107 (40.23%), ROSO in 51 (19.17%) and vitreous hemorrhage 33 (12.41%). Endophthalmitis was indication in 20 (7.52%), dropped nucleus in 11 (4.13%), Macular hole in 7 (2.63%) and ERM in 3 (1.13%). Asteroid hyalosis, intraocular IOFB and diagnostic vitrectomy were least common indication, each seen in 1 (0.5%) patient. Silicon oil was most commonly used Endo tamponade used in 138 (51.88%) patients. All patients were followed for 6 months with vision and retinal status. All patients who underwent pars plana vitrectomy surgery were stable with anatomical success rate till 6 months postoperatively except 10 (3.76%) who required re do operation for retinal detachment or some other complications. Conclusion: Current practice in ophthalmology shows increased frequencies of internal approach (PPV) for vitreoretinal diseases rather external approach (SB). Silicon oil was most common internal tamponade used. Diabetic retinopathy was important cause of vitreous hemorrhage and TRD. Patients should be educated regarding regular fundoscopy and good systemic control of diabetes. Higher incidence of retinal detachment among all age groups needs awareness and education about its warning ocular symptoms. Key words: PPV (Pars plana vitrectomy), RRD (Rhegmatogenous retinal detachment), SB (Scleral buckling), TRD (Tractional retinal detachment), ROSO (removal of silicon oil), GA (general anesthesia), LA (local anesthesia)

This study aimed to investigate morphological differences between idiopathic epiretinal membrane (ERM) and secondary ERM due to peripheral break (SEPB) and to identify clinical characteristics in eyes with SEPB to facilitate peripheral retinal examination. The retrospective cross-sectional study involved 93 consecutive eyes in 91 patients who underwent ERM removal surgery. Eyes were divided into two groups: the macular pucker group and the idiopathic ERM group. En-face Optical Coherence Tomography (OCT) images, fundus photographs, severity of metamorphopsia (M-score) and clinical characteristics of each group were compared. ERM extent and eccentricity (ratio of the shortest and longest distances from the foveal center to the boundary) were obtained through en-face OCT imaging. Fundus photographs were used to judge whether the membrane was turbid or not. Patients with SEPB were younger than patients with idiopathic ERM (61.3 ± 7.5 vs. 66.6 ± 8.3 years; p < 0.05). Preoperative M-score and myopic refractive error, axial length were also significantly higher in the macular pucker group than in the idiopathic ERM group (all p < 0.05). There was no difference in ERM extent between the two groups. The incidence of ERM eccentricity was 23 of the 34 eyes (67.6%) in the SEPB group and 26 of the 59 eyes (44.1%) in the idiopathic ERM group (p < 0.05). The incidence of turbid ERM was 18 of the 34 eyes (52.9%) in the SEPB group and 10 of the 59 eyes (16.9%) in the idiopathic ERM group (p < 0.01). The SEPB group, compared with the idiopathic ERM group, tended to have eccentric, turbid ERM at a younger age and with more severe metamorphopsia and myopic refractive error.
