ABSTRACT
Introduction: Corneal disease ranks 5th among the causes ofblindness and it forms 7.1% of total blindness and is a seriouspublic health problem resulting in medical and economicburden to the nation. A study was carried out to evaluateregrafts with emphasis on factors which caused failure oforiginal graft and factors influencing graft success after repeatPK.Material and methods: The prospective study consisted ofcases of graft failure attending Eye Bank Clinic at CommandHospital, Kolkata, from Jan 2017 to Dec 2018. Intervalbetween primary graft and repeat PK was minimum of 06months. All the surgeries were performed by a single surgeon.Results: Out of 164 PK, 28 regraft (17.07%) were performed.The regrafting were carried out on cases of graft failure dueto endothelial failure (39.3%), allograft rejection (17.8%),recurrence of disease (14.2%), secondary glaucoma (10.7%),ocular surface disorder and dry eye (10.7%), Pseudomonasinfection (3.6%) and unknown (3.6%). In 13 cases simplerepeat keratoplasty and in rest 15 cases combined procedureswere done. 17 cases (60.7%) had clear regrafts and in 11cases the regraft became opaque during follow up period of06 months to 2 years (average 12.6 months). Pseudophakicbullous keratopathy had greater rate of clear regrafts (71.4%).09 out of 11 cases of failure had one of the preoperative factorslike raised IOP, anterior synechiae, corneal vascularizationand younger recipient age group. Vascularization of recipientbed was associated with greater rate of graft failure (60%).Conclusions: Better visual outcome and graft survival inregraft can be achieved by understanding the underlyingpathology and formulating a preoperative plan.
ABSTRACT
Introduction: Eye diseases incidence and prevalence varieswith the social and environmental factors. Present researchaimed to study the prevalence of various common eye diseasesat a Tertiary Care United Nations hospital.Material and methods: It is a retrospective study of all newpatients attending the eye OPD of a tertiary care UN hospitalduring three years period Sept 2007 to Aug 2012. All patientsunderwent a thorough routine eye examination involvingvision testing by Snellen’s chart, Refraction, Tonometry, Slitlamp examination of Anterior Segment, Fundus examinationand Color Vision. Cases were also subjected to automatedperimetry, laboratory and radiological investigations ifconsidered essential.Results: A total of 217 (401) new patients attended theeye clinic. Patients attending the eye clinic were of variednationality which included patients from India, Pakistan, SouthAfrica, Uruguay, Congo, England, Iraq, Italy, Bangladesh,Netherlands, Nepal, USA etc. The three most commoncauses of eye disorders were refractive error followed byallergic conjunctivitis and Presbyopia. However, cases ofOnchocerciasis were also seen especially in those belongingto Congo. Mostly the patients were in the age group of 30-40yrs (35.4%) and 40-50 yrs (41.01%) being active militarysoldiers. Presbyopia was more common in age group 40-50yrsof age (73.3%). Majority of patients were mainly extra ocularcases (95.4%).Conclusion: The pattern of prevalence of various oculardiseases is similar to other parts of world in this age groupand with a similar occupational profile. This study will go along way in ensuring optimum provisioning of eye health carepersonnel’s and equipment for efficient eye care services.
