Results: It is observed that values of tear break up time, Schimer I and Schimer II were decreasing at one week and one month post LASIK as compare to one week pre LASIK values. Mean tear break up time at one week of pre LASIK was 14.72 ± 1.08 seconds (P=0.000), at one week post LASIK was 13.64 ± 1.507 seconds (P=0.000) and at one month post LASIK was 13.02 ± 1.695 seconds (P=0.000). Conclusion: Laser in situ keratomileusis (LASIK) significantly changes tear film stability and tear secretions for at least one month post operatively.
Objective: To determine the efficacy of Schirmer’s I test and TBUT test in dry eye changes in type II diabetic patients. Subjects& Methods: In these prospective study 58 (116 eyes) dry eye patients with diabetesmellitus type II patients with minimum duration of 5 year, with BCVA of 6/12 to 6/6. After baseline examination, TBUT Test and Schirmer’s Test I were performed to measure dry eye changes occurred due to DM type II.As the data was not normally distributed therefore Wilcoxon sign rank test were applied using p-value ≤0.05 as significant. Results:In the current study on average duration of diabetes was 5.90±1.17 (Range 5-9)years. 30(50.8%) had 5 years history of diabetes, 15(25.4%) had 6years, 7(11.9%) has 7years, 4(6.8%) had 8years and 3(5.1%) had 9 years history of diabetes. Schirmer's Test I Ocular Dexter (OD) &Oculus Sinister (OS) were 12.90±3.65mm and 12.56±3.23mm. Mean difference was statistically significant (p-value 0.022). Whereas mean TBUT of Ocular Dexter (OD) &Oculus Sinister (OS) were 18.81±6.730 and 19.63±7.083 respectively, the mean difference was not statistically significant (p-value 0.342). Differences between TBUT & Schirmer’s I test of OD and TBUT & Schirmer’s I test of OS were statistically significant (p-value <0.001). Conclusion: This study evaluates that TBUT Test are much significant as compared to Schirmer’s test because they have so much difference in their Mean ± Std. Deviation. Keywords: TBUT Test, Schirmer’s Test I, Diabetes type II, Dry Eye.
Objectives: To determine the effect of LASIK on tear film stability. Study Design:Cross sectional, prospective study. Setting: The study was conducted in D. G. Laser Vision andDiagnostic Center, D.G. Khan, South Punjab, Pakistan. Period: From March 2016 to September2016. Materials and Methods: One hundred patients (two hundred eyes) were selected forthis study. SPSS version 20 was used to analyze the data. Categorical variables presented asfrequency and percentages and numerical variables presented as mean ± standard deviation.Results: It is observed that values of tear break up time, Schimer I and Schimer II were decreasingat one week and one month post LASIK as compare to one week pre LASIK values. Mean tearbreak up time at one week of pre LASIK was 14.72 ± 1.08 seconds (P=0.000), at one week postLASIK was 13.64 ± 1.507 seconds (P=0.000) and at one month post LASIK was 13.02 ± 1.695seconds (P=0.000). Conclusion: Laser in situ keratomileusis (LASIK) significantly changestear film stability and tear secretions for at least one month post operatively.
Objectives: To compare the status of stereopsis in anisometropic amblyopicpatients of 11-30 years of age and the type of anisometropic amblyopia associated with deficientBSV in patients of Eye OPD of Shalamar Hospital, Lahore. Study design: Descriptive crosssectional study Setting: Eye OPD, Shalamar Hospital, Lahore. Duration: From August 2015to August 2016. Materials and Methods: Two hundred (200) patients were selected for thestudy. Computor software SPSS version 16 was used to analyze the data. Categorical data waspresented as frequencies and percentages and numerical data presented as mean ± standarddeviation. Results: Frequency of anisometropic amblyopia is relatively higher in age groups 26-30. Age group 11-15, 16-20 and 21-25 have relatively low rate of amblyopia due to anisometropia.P = 0.000 a significant value. Conclusion: Frequency and severity of anisometropia in thisclinical sample from the Eye OPD of Shalamar Hospital, Lahore that increased as the level ofametropia increased. Both spherical ametropia and astigmatism were independently associatedwith anisometropia. Furthermore, both Spherical and cylindrical anisometropic amblyopia areindependently associated with deficient BSV. Simple hypermetropic amblyopia was the mostcommon cause associate with deficient BSV. The commonly affected age group in our studywas 25-30 year.
