Background: The eye and vision related problems that results from continuous use of computers and other visual display terminals for extended period of time leads to computer vision syndrome. Due to rapid digitalization in human life, the risk of developing it has also increased in many folds. So, with an aim of determining the prevalence and level of awareness of computer vision syndrome among computer users along with their attitude and practices to prevent it, this study was conducted in the office employees who use computer for a considerable period of time. Materials and Methods: A hospital based observational descriptive study was conducted in the out-patient department of Ophthalmology in Nobel Medical College and Teaching Hospital, Biratnagar, where 105 employees working in different work stations of same institution were enrolled. A questionnaire and the clinical findings were used to collect data. Results: About 80% of the employees were using computer for about (8-11) hours per day. Prevalence of computer vision syndrome noted was (92.4%) with low level of knowledge (85.7%) about it. About 45% of them wore glasses for their refractive errors but attitude and practices in work place to prevent the bad effects of using visual display terminals were found to be lacking (53.3%). Burning sensation in the eye, headache, ocular irritation and itching and neck, shoulder or back pain were the common symptoms. Around (60-70)% of the eyes tested positive for dry eye. Conclusion: Lack of awareness of computer vision syndrome and lack of personal protective measures were associated with its high level of prevalence.

Permukaan okular rentan terhadap efek iritatif dari debu semen tersebut karena epitel konyungtiva dan kornea hanya dilapisi oleh lapisan tipis tear film. Paparan debu semen jangka panjang menyebabkan terjadinya inflamasi subklinis kronik yang dapat mempengaruhi transdiferensiasi epitel konyungtiva dan densitas sel goblet yang kemudian dapat menyebabkan timbulnya gejala dry eye syndrome. Tujuan penelitian ini adalah menilai status tear film pada masyarakat  yang  terpapar  emisi  debu  semen  dibandingkan  dengan  masyarakat  yang  tidak  terpapar.  Penelitian ini berupa analytic cross sectional study pada dua populasi yaitu kelompok terpapar dan tidak terpapar emisi debu pabrik semen. Semua sampel penelitian dari dua populasi menjalani pemeriksaan pH tear film, Schirmer, Ferning dan Tear Break Up Time (TBUT). Hasil studi mendapatkan peningkatan nilai pH tear film yang bermakna pada penduduk di kelompok terpapar dengan p=0.001. Terdapat juga penurunan kualitas Ferning yang bermakna pada penduduk di kelompok terpapar yang didominasi tipe III dengan p=0.005 dan 0.029. Sedangkan hasil pemeriksaan Schirmer dan TBUT masih dalam batas normal dan tidak terdapat perbedaan yang bermakna antara kedua kelompok. Simpulan studi ini ialah erdapat peningkatan rerata nilai pH tear film dan penurunan kualitas lapisan musin tear film yang bermakna pada masyarakat yang terpapar emisi debu semen namun tidak didapatkan peningkatan kejadian dry eye yang bermakna.

Schirmer I Test

Purpose: To determine the association between tear film thickness (TFT) as measured with ultra-high resolution optical coherence tomography (UHR-OCT) and signs and symptoms of dry eye disease (DED). Methods: A total of 450 eyes from 225 patients with DED from six different randomized clinical trials were included in this pooled analysis. In all subjects, TFT was measured with a custom-built UHR-OCT system. Symptoms of DED were quantified using a standardized Ocular Surface Disease Index (OSD)I questionnaire and clinical signs including tear film break up time (TFBUT) and Schirmer I test were assessed. Associations of the average TFT with OSDI, TFBUT, and Schirmer I test were calculated using a linear regression analysis. Results: The average TFT of the included sample (mean age, 45.0 ± 13.3 years; 65% female) was 4.2 ± 0.5 µm and the OSDI 36.2 ± 10.4. A significant negative correlation was found between TFT and OSDI (r = −0.36 to −0.31; p < 0.001). Tear break up time and Schirmer I test were not correlated with OSDI. Significant albeit weak correlations were found between TFT and TFBUT (r = 0.17 to 0.25; p < 0.01) as well as Schirmer I (r = 0.36 to 0.37; p < 0.001). Subgroup analysis revealed that the correlation was stronger in the subjects with abnormal Schirmer I (<15 mm; r = 0.50 to 0.54; p < 0.001). Conclusions: The present study demonstrates an objective measurement of TFT using a novel OCT approach for DED that correlates with symptoms and signs of DED. Our data are consistent with the idea that TFT represents the aqueous-deficient component of DED.

Upper Blepharoplasty

Objectives: To investigate the changes of dry eye-related clinical manifestations, ocular surface parameters, and tear inflammatory cytokines after upper blepharoplasty.Methods: Forty eyes of 20 who underwent upper blepharoplasty were divided into either the group with or the group without preexisting dry eye before upper blepharoplasty. Ocular Surface Disease Index (OSDI), Schirmer I test, tear meniscus height, lipid layer thickness, non-invasive tear break-up time (NIKBUT), fluorescein tear film break-up time (FBUT), corneal fluorescein staining, meibum expression, lid margin changes, and tear inflammatory cytokines were assessed preoperatively and at 1, 3, and 6 months postoperatively. Correlations between inflammatory cytokines and dry eye-related parameters were determined.Results: The OSDI scores increased significantly at 1 month (p = 0.040) and subsequently decreased to the preoperative levels at 6 months postoperatively in subjects with dry eye. First (f)-NIKBUT and FBUT were significantly shortened at 1, 3, and 6 months postoperatively in subjects with dry eye (f-NIKBUT: p &lt;0.001, p = 0.010, p = 0.042; FBUT: p = 0.002, p = 0.005, p = 0.037, respectively), but were only shortened at 1 month (p = 0.028, p = 0.005) and returned to baseline levels at 6 months postoperatively in subjects without preexisting dry eye. A significant increasing trend of interleukin (IL)-6 was found in both dry eye and subjects without preexisting dry eye (p = 0.016, p = 0.008), while IL-8 and tumor necrosis factor alpha (TNF-α) were only found to be increased in subjects with dry eye postoperatively (p = 0.031, p = 0.031). The levels of IL-8 and TNF-α were positively correlated with OSDI scores (p = 0.046, p = 0.043, respectively) and negatively correlated with f-NIKBUT and FBUT (p = 0.026, p = 0.006, respectively).Conclusions: Upper blepharoplasty might increase the release of tear inflammatory cytokines and tear film instability that contribute to the development of postoperative dry eye in the early postoperative period and the changes most relieved in 6 months. Preexisting dry eye is a higher risk factor for worse and persistent ocular surface damage after upper blepharoplasty.

Single Centre Study

Introduction : In the ocular surface there is a well- coordinated system of enzymes that can produce urea independent of external urea supply. Urea locally formed from ocular tissues is important for the composition of the tear fluid. In eyes with dry syndromes this production is affected. Estimation of urea levels in the lacrimal fluid may prompt a newer treatment for dry eyes utilising urea. This study was done to evaluate the correlation between serum urea levels and pathophysiology of dry eye syndromes. Materials and methods: A prospective, observational, single-centre study. 50 patients of dry eye disease were included in the subjects and 50 controls were included in the study based on schirmer’s test. Tear film urea was estimated wih semi autoanalyser erba chem 5. When sample volume was not sufficient it was diluted with sterile water and urea was estimated after calculating for dilution factor. Blood urea was estimated with Erba Chem EM 360 working on similar principle Results: In the test group, the urea level in tear film ranged from 14.01 mg % to 39 mg % with a mean of 26.78 +/- 5.70 mg %. In the controls the levels of urea in the tear film ranged from 21.06 mg% to 56.00 mg% with a mean of 41.72±6.86 mg%. Conclusions: Levels of urea in tear film in normal individuals without dry eyes is similar to urea levels in the blood. Tear film urea levels were significantly lower in patients with dry eye diagnosed with Schirmer’s Test. Decreased tear film urea level in dry eyes is unrelated to blood urea levels and may play a role in the pathophysiology of dry eyes. This needs further investigation.
