ABSTRACT
Objective: To determine the causes of poor visual outcome after bilateral congenital/ developmental cataract surgery, like posterior capsular opacification, strabismus, glaucoma, retinal detachment and endophthalmitis in a teaching hospital, Lahore Pakistan
Methods: This prospective study was conducted in Eye unit 1, Services Hospital, SIMS, Lahore from January,2010 to January, 2016. During this periodwe evaluated 80 eyes in 40 children aged 6 years to 12 years with bilateral congenital cataract with no other associated posterior segment pathology. Male children were 26 and female were 14 in number. Follow up period was for 6 years. A comprehensive detailed history, demographic data, surgical techniques and causes of poor visual outcome was noted like posterior capsular opacification, glaucoma, strabismus, retinal detachment and endophthalmitis
Results: The incidence of posterior capsular opacification was observed in 45%,glaucoma in 2.5%,strabismus in 12.5%. Retinal detachment and endophthalmitis was not observed in any child after bilateral congenital cataract surgery
Conclusion: The present study revealed that the early detection and treatment including refractive rehabilitation and regular and close follow-up are essential for good visual outcome. Better visual outcome can further be improved by parent's guidance and motivation postoperatively
ABSTRACT
Objective: to determine the prevalence of posterior capsular opacification in congenital cataract surgery after intravitreal dexamethasone and subconjunctival mydricaine injections
Material and Methods: this prospective study was conducted in Eye unit 1, Services Hospital, SIMS, Lahore from 21/7/2008 to 26/6/2013. During this period we evaluated 30 eyes in 30 children aged 4 months to 2 years with congenital cataract with no other associated anterior or posterior segment pathology after intravitreal dexamethasone and subconjunctival mydricaine injection. A comprehensive detailed history, demographic data, surgical techniques and the prevalence of delayed post-operative co plication like posterior capsular opacification was noted
Results: the incidence of posterior capsular opacification was observed in 64% of the congenital cataracts after surgical intervention with intravitreal dexamethasone and subconjunctival mydricaine injections
Conclusion: the present study revealed that use of intravitreal dexamethasone and subconjunctival mydricaine injections during paediatric cataract surgery provides better surgical outcome in terms of clearer visual axis due to less inflammation and synechiael formation which decreases the incidence of posterior capsular opacification in these cases of congenital cataracts
ABSTRACT
Objective: to detect and assess posterior segment pathology in cases of vitreous hemorrhage by ultrasound examination in patients presenting to ophthalmology department of Services Institute of Medical Sciences, Lahore
Material and Methads: this study included 179 patients [200 eyes] with vitreous hemorrhage who underwent A and B scan ultrasound by one examiner at Eye unit I in Services Hospital, affiliated to Services Institute of Medical Sciences, Lahore, for the duration of four years from January 2003 to January 2007. 114 were male and 65 were females. All patients had dense vitreous hemorrhage prevented visualization of the retina. Age range was between 10 to 67 years. Before ultrasound, all the patients were completely examined in OPD including a comprehensive history, record of visual acuity and intraocular pressure, Detailed fundus examination was carried out after dilatation of pupils with mydriacyl [tropicamide] eye drops with 78 D lens and Indirect ophthalmoscope
Results: unilateral cases were 60 and bilateral cases 70. Proliferative diabetic retinopathy with vitreous hemorrhage was observed in 90 eyes, [tractional retinal detachment was present in 38 eyes, both tent like and table top configuration were observed on B scan white vitreous hemorrhage with proliferative diabetic retinopathy was observed in 52 eyes]. Rhegmatogenous retinal detachment was observed in 10 eyes. Vitreous: hemorrhage due to penetrating injuries occurred in 55 eyes and out of these 55, rnetallic intra-ocular foreign body was present in 05 eyes. Eales disease with vitreous hemorrhage was present in 25 eyes. Posterior vitreous detachment was noted in 20 eyes with vitreous haemorrhage
Conclusion: ultra-sound surgeons A-and B-ultrasound the most important examination tool. It should be typically performed early and frequently after presentation of patient with vitreous hemorrhage
ABSTRACT
Background: To outline the need / use of investigations in cases of uveitis
Methods and Patients: This study was carried out from April 2001 to July 2004 in Unit I affiliated to Services Institute of Medical Sciences, Lahore. Total duration was more than 3 years. All the patients underwent complete ophthalmological and medical evaluation. Eye examination included record of visual acuity, intraocular pressure, slit lamp biomicroscopy and examination of the posterior segment with indirect ophthalmoscope and 78D lens. Baseline screening tests were advised in all cases of uveitis. Special investigations were ordered only when there was high clinical suspicion of systemic diseases
Results: 69 eyes of 42 patients of uveitis of different varieties were followed for more than 3 years. 71% of patients were males while 29% were females. 60% of the patients belonged to younger age group between 20-39 years of age. Anterior uveitis was present in 69% of patients; 20% of these patients had unilateral recurrent anterior uveitis while 21% had posterior uveitis, and remaining 10% had other types of uveitis. Baseline screening tests revealed raised ESR in all 42 patients and lymphocytosis in the patient with carcinoma of prostate. All other investigations whether baseline or specialized were negative
Conclusion: We conclude that detailed investigations are not justified in all patients of uveitis and they should be ordered only when a reasonable chance exists that they will provide useful diagnostic information for a particular patient
