Retinal Detachment Surgery at Nepal Eye Hospital
Introduction:Retinal diseases are one of the important causes of blindness in Nepal. This study is
done with objectives of fi nding the outcome of retinal detachment surgery.
Methods:A retrospective analysis of 110 patients who underwent retinal detachment surgery over
fi ve year period was conducted in Nepal.
Results:Retinal re-attachment was achieved in 94.4 % and postoperative visual acuity of 6/36 to 6/6
was achieved in 52.7% (As possible risk factors, myopia was present in 34.5% ophkia in 29%, trauma
in 9%, and lattice) degeneration was 5.4%.
Conclusions:The study has shown a promising result for the retinal detachment surgery.

Background: Post-operative endophthalmitis remains one of the most visually devastating complications of cataract surgery. Cluster endophthalmitis is defined as five or more cases of endophthalmitis occurring on a particular day in a single operating room in one centre. Excessive inflammation, particularly in the early post-operative phase, should be regarded as infective endophthalmitis. Early diagnosis and immediate intervention in such case, lead to salvage of eye as well as better visual outcome. Objective: To find out the causative organisms and visual outcome after an outbreak of post-operative endophthalmitis in high volume cataract surgical centre. Materials and methods: Retrospective, interventional case series of 19 patients with acute post-operative endophthalmitis after manual small incision cataract surgery in a single day, underwent vitreous tap and received intravitreal Vancomycin, amikacin and Dexamethasone. Subconjunctival vancomycin was given at the end of the procedure. Vitreous samples were stained using Grams stain, Giemsa stain and KOH mount. Samples were sent to the hospital’s microbiology laboratory for culture and sensitivity testing. All patients received intravenous ciprofloxacin for 3 days and oral ciprofloxacin for 7 days. Topical Prednisolone acetate, Ofloxacin, Gentamycin and atropine were given to all patients. Patients were followed up till 6 weeks

Village-integrated eye workers for prevention of corneal ulcers in Nepal (VIEW study): a cluster-randomised controlled trial
BackgroundCorneal ulcers are a common cause of blindness in low-income and middle-income countries, usually resulting from traumatic corneal abrasions during agricultural work. Antimicrobial prophylaxis of corneal abrasions can help prevent corneal ulcers, but delays in the initiation of therapy are frequent. We aimed to assess whether a community-based programme for corneal ulcer prevention would reduce the incidence of corneal ulceration.MethodsA cluster-randomised trial was performed in village development committees (VDCs) in Nepal. VDCs in the catchment area of Bharatpur Eye Hospital, Nepal with less than 15 000 people were eligible for inclusion. We randomly assigned (1:1) VDCs to either an intervention group or a control group. In the intervention VDCs, existing female community health volunteers (FCHVs) were trained to diagnose corneal abrasions and provide a 3-day course of ophthalmic antimicrobials to their patients. In the control VDCs, FCHVs did not provide this intervention. Participants were not masked given the nature of the intervention. Both groups were followed up for 3 years for photographic evidence of corneal ulceration. The primary outcome was the incidence of corneal ulceration, determined by masked assessment of corneal photographs. The analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, NCT01969786.FindingsWe assessed 112 VDCs, of which 24 were enrolled. The study was performed between Feb 4, 2014, and Oct 20, 2017. 12 VDCs were randomly assigned to the intervention group and 12 to the control group. 252 539 individuals were included in the study (130 579 in the intervention group and 121 960 in the control group). FCHVs diagnosed and provided antimicrobials for 4777 corneal abrasions. The census identified 289 corneal ulcers among 246 893 person-years in the intervention group (incidence 1·21 cases [95% CI 0·85-1·74] per 1000 person-years) and 262 corneal ulcers among 239 170 person-years in the control group (incidence 1·18 cases [0·82-1·70] per 1000 person-years; incidence rate ratio 1·03 [95% CI 0·63-1·67]; p=0·93). Medication allergy was self-reported in 0·2% of participants.InterpretationWe did not detect a reduction in the incidence of corneal ulceration during the first 3 years of a community-based corneal ulcer prevention programme. Further study might be warranted in more rural areas where basic eye care facilities are not available.FundingNational Eye Institute
