BACKGROUND The main attributes of cornea which makes it optically important is its ability to maintain its dehydrated state. This corneal dehydration can be achieved and maintained by various factors among which corneal endothelial cell count and morphology play a significant role. Corneal attributes considered in this study i.e. the corneal endothelial cell count and central corneal thickness are extremely variable, and changes are seen even with smaller changes in anterior segment or overall structural changes in eyes. We wanted to compare central corneal thickness in emmetropia and axial myopia and compare corneal endothelial cell count in emmetropia and axial myopia. METHODS The sample size was decided taking into consideration various prevalence studies. The patients were consecutively recruited for the study considering the inclusion and exclusion criteria. The subjects were divided into two groups emmetropia and axial myopia and were differentiated on the basis of the axial lengths. Specular microscopy was performed for the subjects and corneal endothelial cell count, morphology and central corneal thickness were measured, and comparative study was performed. RESULTS This study of 80 eyes shows us that the difference between mean the corneal endothelial cell count between emmetrope (2812.80 cells / mm2) and axial myopes (2653 cells / mm2) is statistically significant where p was < 0.05 while the mean central corneal thickness measurements didn’t show statistically significant change between emmetrope (490.05 microns) and axial myope. (489.37 microns). CONCLUSIONS Axial length has an indirect correlation with the corneal endothelial cell count which is statistically significant. While significant correlation between the central corneal thickness and axial length cannot be established in this study.

Purpose To evaluate efficacy and safety of contact lens-assisted corneal cross-linking (CACXL) among progressive keratoconus patients with thin corneas. Setting Private eye hospital Design Cross-sectional study Methods Thirty-six eyes of 36 consecutive patients with progressive keratoconus and thinnest corneal thickness of 380–400 µm after epithelium removal were included. CACXL was performed based on use of a dextran-free isotonic (>0.1%) riboflavin solution with hydroxypropyl methylcellulose (HPMC, 1.1%) after epithelial removal and placement of a riboflavin-soaked contact lens without an ultraviolet filter on the cornea and ultraviolet irradiance. Data on best distance corrected (CDVA) and uncorrected (UDVA) visual acuity, manifest sphere (D), manifest cylinder (D), K1 (D), K2 (D), mean keratometry (D) and Kmax (D) values, endothelial cell count and mean depth of demarcation line were recorded preoperatively and at the postoperative 1-year Results Post-operative 1-year data revealed significant increases in UDVA (0.23  ±  0.15 vs. 0.17  ±  0.13 D, p < 0.001) and CDVA (0.44  ±  0.18 vs. 0.36  ±  0.17 D, p < 0.001) values and a significant reduction in the mean Kmax (from 56  ±  3.3D to 55  ±  3.2 D, p < 0.001), K2 (from 49.7  ±  3.2 D to 49.52  ±  3.11 D, p  =  0.049), manifest sphere (from −1.93  ±  2.21 D to −1.55  ±  2.02 D, p  =  0.001) and manifest cylinder (from −2.83  ±  1.67 D to −2.39  ±  1.36 D, p < 0.001) values along with a similar endothelial cell count. The mean depth of demarcation line was mean 230 (SD17.05, range 200 to 262) at postoperative 1-month. Conclusions Our findings indicate favourable 1-year postoperative outcome of CACXL in progressive keratoconus patients with thin cornea in terms of improved visual acuity and keratectasia status as well as endothelial safety.

Factors Affecting

<b><i>Purpose:</i></b> The aim of this study was to evaluate the characteristics of corneal endothelial cells and central corneal thickness (CCT) in patients with diabetes mellitus (DM), comparing them with those of healthy subjects (controls) and to determine potential factors affecting the corneal parameters in patients with DM. <b><i>Methods:</i></b> Participants in this study were 72 patients with DM and 88 healthy controls. Diabetic patients were further classified into groups depending on the severity of diabetic retinopathy (no retinopathy, mild, moderate, severe non-proliferative diabetic retinopathy, and proliferative diabetic retinopathy). All participants underwent non-contact specular microscopy to evaluate corneal endothelium parameters and CCT, while factors affecting endothelial cell density and CCT in patients with DM were also analyzed. <b><i>Results:</i></b> Patients with DM presented significantly decreased endothelial cell density compared to controls (2,297.9 ± 311.3 and 2,518.3 ± 243.7 cells/mm<sup>2</sup>, respectively; <i>p</i> &#x3c; 0.001), while the two groups did not differ significantly in any other measured corneal parameter. In the diabetic group, the multivariate analysis showed a significant association between decreased endothelial cell density and increased HbA1c (<i>p</i> &#x3c; 0.001), longer DM duration (<i>p</i> = 0.003), and more severe diabetic retinopathy status (<i>p</i> = 0.008). <b><i>Conclusion:</i></b> DM seems to affect the corneal endothelium, since endothelial cell density was decreased in the diabetic group, while duration of disease, HbA1c levels, and severity of retinopathy were significantly associated with changes in endothelial cell density and should be taken into account.
