Aim: We evaluated metal workers injured with corneal foreign bodies (FB) in terms of health insurance, use of protective eyeglasses, and unprescribed drug use.Materials and Methods: Seventy metal workers who were injured with corneal FB were enrolled in the study. We recorded the gender, age, duration of work, use of protective eyeglasses, and health insurance status data of metal workers. In cases of FB existence, the number of FBs and unprescribed drug use were investigated. We examined the presence of corneal scars that could lead to visual impairment.Results: The mean duration of work was 11.8±10.8 years. Although 29 workers (41.5%) had corneal scars, only three workers (4.3%) had visual impairment due to scars. Also, 29 workers (41.5%) did not report the use of protective glasses; however, 22 (31.4%) workers reported their occasional use and 19 (27.1%) workers reported their routine use. Eighteen workers (25.7%) remarked on topical drug use from time to time. Ten of the 18 patients (55.6%) were using topical Tetrahydrozoline HCL, whereas five (27.8%) were using the topical anesthetic drug 0.5% Proparacaine HCl.Conclusion: Occupational protective measures are important for metal workers who are at a high risk of eye injuries. Workers must be educated on the prevention and treatment of occupational ophtalmological hazards and be warned about the side effects of taking unprescribed drugs.

AIM: To investigate how body temperature(BT)affects choroidal thickness(CT)according to measurements taken with enhanced depth imaging optical coherence tomography(EDI-OCT).METHODS: In this prospective study, the CT of 41 healthy patients was measured hourly from 9:00 to 17:00 at the fovea(SF-CT), 500 μm nasal to the fovea(N-CT), and 500 μm temporal to the fovea(T-CT)using EDI-OCT. BT was also measured hourly from 9:00 to 17:00 using a non-contact infrared thermometer. Possible correlations between diurnal variations of CT and BT were evaluated.RESULTS: SF-CT values significantly differed between measurements at 9:00 and 13:00(P=0.021), 9:00 and 14:00(P=0.012), 9:00 and 16:00(P=0.048), and 9:00 and 17:00(P=0.002). N-CT values also significantly differed between measurements at 9:00 and 13:00(P=0.004), though T-CT did not significantly vary during the 8h period(P >0.05 for all).CONCLUSION: CT is not significantly associated with hourly changes in BT from 9:00 to 17:00.

AIM:To investigate the relationship between pinguecula and the use of tandoor ovens.METHODS:A total of 539 women, ranging in age from 20 to 86y who attended an outpatient clinic were enrolled. All the patients were asked whether they used tandoor ovens. Women exposed to tandoor ovens (n=286) were accepted as participants in the study group and they were compared with participants in the control group (n=253). The age, presence of pinguecula, duration of exposure to tandoor ovens as years and occupations were recorded for all the subjects.RESULTS:Mean duration for exposure to tandoor was 20.26y (range 1-62y) in the study group. The rate of pinguecula in the study group was 82.2% (235/286), and the rate in the control group was 37.5% (95/253); this difference was statistically significant (P<0.05). Pinguecula was seen in 61.2% (330/539) of all the participants.CONCLUSION:Pinguecula is strongly associated with exposure to tandoor ovens.

Purpose. To evaluate the effect of hydroxychloroquine on retinal pigment epithelium- (RPE-) Bruch’s membrane complex, photoreceptor outer segment, and macular ganglion cell-inner plexiform layer (GCIPL) thicknesses using spectral-domain optical coherence tomography (SD-OCT). Methods. In this prospective case-control study, 51 eyes of 51 hydroxychloroquine patients and 30 eyes of 30 healthy subjects were included. High-quality images were obtained using a Cirrus HD-OCT with 5-line raster mode; the photoreceptor inner segment (IS) and outer segment (OS), sum of the segments (IS + OS), and RPE-Bruch’s membrane complex were analyzed. Results. The thicknesses of the IS + OS and OS layers were significantly lower in the hydroxychloroquine subjects compared to the control subjects (P

Purpose. To evaluate the risk factors for post-laser in situ keratomileusis (LASIK) ectasia. Materials and Methods. Medical records of 42 eyes of 28 (10 women, 18 men) patients who developed corneal ectasia after LASIK were retrospectively reviewed. Topographical features and surgical parameters of those patients were evaluated. Results. The mean age of patients was 34.73±6.50 (23–48) years and the mean interval from LASIK to the diagnosis of post-LASIK ectasia was 36.0±16.92 (12–60) months. The following factors were determined as a risk factors: deep ablation (>75 μm) in 10 eyes, FFK (forme fruste keratoconus) in 6 eyes, steep cornea (>47 D) in 3 eyes, pellucid marginal degeneration (PMD) in 2 eyes, thin cornea (
