Abstract

Aims and Objectives: To clinically evaluate the prevalence of dry eyes after manual small incision cataract surgery based on signs and symptoms and, quantifying them using various test methods. Materials and Methods: Follow up of 150 patients who had undergone SICS was done at regular interval starting at 1st week post-operative and continued up to 3rd months. Evaluation is done by performing Schirmer’s test – I, TFBUT, Rose Bengal test followed by noting the symptoms which were relevant to the dry eyes. The observations were analyzed and graded according to the severity of dryness. Results: Most of the patients had mild to moderate dry eye with male domination the female. Severe to very severe dry eyes was seen at 6th post-operative week, mild to moderate dryness of eyes was seen at 2nd & 3rd. weeks. Conclusion: Dryness of eyes is usually seen after small incision cataract surgery and majority being mild to moderate dryness of eyes. Worsening or aggravation of dryness occurred in 6th week’s post-operative interval. Post-operative management of cataract surgery should also include medication to deal with altered ocular surface tears film.

Abstract

Aims: To quantify and compare the retinal nerve fiber thickness in normal, ocular hypertensive and glaucomatous eyes using Optical coherence tomography (OCT). Materials and Methods: Patients were divided in to three groups of 30 each for normal, ocular hypertensive and primary open angle glaucoma. Inclusion criteria were of patients between 30-70 years of age, visual acuity of 6/36 or better, Refractive error not exceeding 5D and no prior surgery. Complete eye evaluation and was done followed by OCT Scan using the protocol “Fast RNFL thickness”. RNFL thickness was assessed in 4 quadrants and statistical analysis was done using student t test and analysis of variance (ANOVA). Results: RNFL was significantly thinner in OHT eyes than in normal eyes specifically in the inferior and nasal quadrants. 12.6% decrease in RNFL thickness was seen in OHT eyes as compared to normal eyes and about 22.29% decrease in RNFL thickness in POAG eyes as compared to OHT. Conclusions: Incorporation of OCT in glaucoma practice can helped us in evaluation of optic disc, quantifying of RNFL, identifying the structural changes in RNFL and the progression of disease. The magnitude of focal RNFL thinning in OCT was related to the magnitude of decreased global indices sensitivity in glaucomatous patient.
