“…[3,5,8,10] Majority of studies on CCT in OHT show that CCT in OHT is thicker than normal subjects, NTG, and POAG [3,4,6,8,10,12,13]. Though CCT in OHT was thicker than NTG and POAG in the current study, we found no significant difference between OHT and controls; this finding is in concert with a study in Spanish population [11].…”

“…CCT in POAG has been found to be equivalent to normal subjects in many studies [3][4][5][6]10,12,22], but there is also evidence of reduced CCT in POAG [11]. We observed that CCT in POAG is thinner compared to normal subjects.…”

“…Copt et al have described that many cases of glaucoma were reclassified after evaluating effect of CCT on measured IOP [5]. Thus, CCT should be considered to estimate actual IOP, to decide who requires closer observation or the initiation of treatment before definite damage occurs, and to establish a target IOP.CCT in patients with ocular hypertension (OHT) is greater and in patients with NTG lower compared to controls, with CCT in primary open angle glaucoma (POAG) falling in between OHT and NTG [3,[5][6][7][8][9][10][11][12][13]. CCT in different types of glaucoma has been evaluated, but Glaucoma suspect (GS) excluding OHT has been ignored in this regard.…”

003 AbstractPurpose: To compare central corneal thickness (CCT) among glaucoma patients, glaucoma suspects, and normal subjects and to determine its association with glaucoma severity in Nepalese population. Methods:This study included 400 eyes (149 glaucoma, 157 glaucoma suspects, 94 controls) of 400 participants examined in a glaucoma clinic and eye OPD in Nepal. CCT was measured by ultrasonic pachymetry. Results:CCT was significantly different among the study groups (P = 0.05), with the thinnest CCT in normal tension glaucoma (NTG) and thickest in ocular hypertension (OHT). CCT (in µm) was thinner in NTG (519.6 ± 31.6; P = 0.06) and primary open angle glaucoma (POAG) (524.5 ± 35.8; P = 0.026) than controls (536.6 ± 28.9); and it was thinner in POAG compared to primary angle closure glaucoma (PACG) (541.3 ± 50.5; P = 0.028) and OHT (559.8 ± 28.1; P = 0.017). In NTG, CCT was thinner compared to Glaucoma suspects (GS) (531.6 ± 35.0; P = 0.038), PACG (P = 0.008), and OHT (P = 0.008).There was no correlation between CCT and visual field defect and CCT was not statistically different between early, moderate and severe POAG groups. Conclusions:We report that CCT in glaucoma suspects is similar to normal subjects and POAG, but thicker than NTG. These data will be important in clinically monitoring glaucoma suspects that are at increased risk of glaucoma. Our results may be population specific and further longitudinal studies are warranted to determine influence of CCT on glaucoma progression in this population.

“…The average CCT differs in various populations and races (La Rosa et al, 2001;Lee et al, 2007). This could be due to the differences in age, gender, genetic factors, weather conditions, diurnal change, diseases (e.g.…”

“…Many studies have indicated that CCT varies from one race or population to another (La Rosa, Gross, & Orengo-Nania, 2001; Lee, Kim, Ha, Seong, & Hong, 2007;Morad., Shavon, Hefetz, & Nemet, 1998;Hashemi et al, 2013). Thus, special weather conditions and race in this region of Iran might be another strong cause of conducting the current research.…”

Anterior segment eye parameters are essential factors in diagnosis, screening and management of abnormal ocular conditions. Based on the previous studies, they might differ from one race or population to another. Sistan-and-Baluchestan province, the southeast of Iran, has special weather conditions and race, plus lack of research on these diagnostic factors. Hence, the objective of the present study was to assess anterior segment parameters using pentacam in this area. 800 eyes of subjects which had been referred to the Al-Zahra eye hospital of Zahedan, the capital city of the province, for corneal refractive surgery from October 2014 to March 2015 participated in this research. 95% confidence limits for mean of central corneal thickness, anterior chamber depth and volume were (536.02, 541.20), (3.13, 3.18) and (187.63, 192.58) respectively. Multiple linear regression models showed a lower mean central corneal thickness, and maximum/minimum of keratometry, for males than females, adjusting for age and spherical equivalent. Inversely, anterior chamber depth, and volume were more in males. In order to diagnosis and treating ocular diseases which have effect on retinal thickness, precisely specification of predictive factors is highly needed.
