To describe the management, complications and prognosis of lacrimalprobing in patients with congenital nasolacrimal duct obstruction (CNLDO).
 
  Retrospective, observational and analytical study. We studied the prevalence, symptoms and signs, both before and after probing, in patients with CNLDO diagnosed between 2010 and 2017 at Instituto Fundación Conde deValenciana.
 
  The prevalence at our hospital of congenital nasolacrimal duct obstruction in children less than 1 year of age was 16.1%. 71 eyes of 56 patients undergoing probing were analyzed. 61% of patients were male. The right eye was affected in 46.4%.The average age of diagnosis of CNLDO was 10.2±7.6 months. 84.5% consulted for excessive tearing and 73.2% because of eye discharge. On ophthalmological examination, 71.8% had increased tear meniscus and 45.1% had discharge from punctum when digital pressure was applied to the lacrimal sac.  https://www.selleckchem.com/products/CP-690550.html  The average age at the time of probing was 14.1±8.4 months. Subsequent to the probing, only 21.1% reported presence of tearing and 5.6% reported ocular discharge, both with a statistically significant reduction (p<0.05 from pre-op). After probing, only 16.9% of eyes had increased tear meniscus and 11.3% presented discharge from punctum after pressure at the lacrimal sac. Both decreases were statistically significant (p<0.05). 2 eyes (2.82%)of 2 patients required a second probing to obtain full resolution.
 
  Probing was successful in 76.1% of eyes. Success was observed even inpatients over 2 years of age. There was a statistically significant decrease of both signs and symptoms of CNLDO with lacrimal probing.

  This study has attempted to assess the profile and treatment outcome of patients with OSSN and report the recurrence rate following treatment of primary OSSN.
 
  This was a retrospective, non-comparative hospital based observational study. The case files of OSSN patients from Jan 2010 to Dec 2017were assessed. The study site was Himalaya Eye Hospital, Gharipatan, Pokhara. This hospital is the only eye hospital in province 4, Nepal. All the files of suspicious cases of conjunctival mass or OSSN were reviewed. Data regarding demographic characteristics, vision acuity, involved eye, clinical features, conjunctival lesion type, duration of symptoms, preoperative clinical diagnosis, history, other eye disease, associated systemic diseases, occupation as well as treatment modalities of the patients and its outcome were taken.
 
  Out of 40 cases, females were 21(52.5%) vesus 19(47.5%) male. Amongthem, 19 patients had keratinized stratified squamous epithelium, 17 had conjunctiva intraepithelial squamous neoplasia ansfactory. Further studies with prolonged follow-up are recommended to evaluate the risk of recurrence and other adverse effects.
  To determine the surgical and visual outcomes of posteriorly dislocated lens fragments in the vitreous cavity in patients undergoing cataract surgery.
 
  A total of 149 eyes of 149 patients from 2013 to 2018 were included in the study. The primary cataract surgery was performed either at the base hospital and its peripheral centres or referred from elsewhere. Pars plana vasectomy and nucleus removal was performed along with implantation of intraocular lens, wherever possible. Success was defined as best corrected visual acuity (BCVA) ≥ 6/12 at 3 months follow up. Poor visual outcome was defined as per WHO guidelines as BCVA ≤ 3/60.
 
  Posterior capsular rupture and dislocation into vitreous cavity most frequently occurred during phaco-fragmentation in cases of phacoemulsification and during nucleus delivery in cases of small incision cataract surgery. Early vitrectomy was performed within 3 days in 36.2% of cases and within 14 days in 63.8% of cases. Successful visual outcome was achieved in 85.2% of patientsns can be successfully managed in majority of cases with vitreoretinal surgical intervention. The timing of vitrectomy whether performed early or late did not affect the visual outcome. The most important predictorof final visual acuity after PPV for retained lens fragments is a less complicated clinical course without any associated complications such as retinal detachment, cystoidmacula edema and glaucoma. Expertise of the primary cataract surgeon could not be assessed in this study, though surgeon grade with more experience is an important factor in the assessment of complications during the cataract surgery.
  To study the incidence and progression of refractive errors in medical students.
 
  This is a retrospective study including 200 medical students of our college during the period of July 2015 to June 2018. Examination included visual acuity testing using Snellens chart, slit lamp biomicroscopy, fund us examination with direct ophthalmoscope, indirect ophthalmoscope and refraction. Students were examined for refractive errors and findings compared with pre-admission data. Changes in spherical, cylindrical power analysed.
 
  Prevalence of Myopia increased from 40% to 48%. Incidence of new refractive errors in emmetropes was 8%. Myopic change found was -0.75D to -1.0D.
 
  Students in medical colleges have high prevalence of myopia, high incidence of adult onset myopia and statistically significant progression. Parental history, prolonged eye strain, excessive use of electronic gadgets, decreased outdoor activity and urban background had significant association with prevalence of myopia.

  Intraocular lymphoma is rare. There are very few studies on intraocular lymphoma published from Asian countries.
 
  To report our case series of intraocular lymphoma patients from a tertiary eye centre in Singapore.
 
  Nine patients with intraocular lymphoma managed between January 2005 and December 2014 were identified from Ocular Autoimmune Systemic Inflammatory Infectious Study (OASIS) database. Demographic characteristics, clinical presentation, investigations performed and outcomes recorded.
 
  There were almost equal distribution between males (four patients) and females (five patients) with mean age of presentation was 60.3 years. Five patients had bilateral involvement and vitreo-retina was the most common site of infiltration. All of our patients had central nervous system involvement although four of them had presented with ocular manifestations initially. Anterior chamber fluid cytology, as a less invasive alternative to vitreous analysis was proven to be useful. The time from ocular presentation to diagnosis of ocular lymphoma was variable; from one day to 18 months.
