“…Previous reports indicated that certain parameters such as age, race, refractive error, and axial length could affect OCT findings in the retina [22]. Although corneal irregularities present in KCN can compromise the optical quality of OCT retinal images, the technique can still reliably record retinal layer thicknesses in these patients [7,[23][24][25][26].…”

“…The technique has the potential to reveal macular lesions due to various conditions and it is valuable for visualization of, for example, macular oedema. OCT has been shown to be able to measure retinal thickness despite the reduced optical quality of the cornea in KC subjects [ 12 – 14 ]; however, very little data is available to demonstrate if macular thickness is normal or unaffected by the disease. Therefore, the aim of this study was to compare the macular thickness in patients with KC with macular thickness in healthy subjects.…”

Purpose. The aim of the present study was to compare macular thickness in patients with keratoconus (KC) with macular thickness in healthy subjects. Subjects and Methods. Twenty-six patients with KC and 52 control subjects were included. The macular structure was evaluated using a Zeiss Cirrus HD-OCT. The scan pattern used was 512 × 128, which covers an area of approximately 6 × 6 mm of the retina. The cube volume was assessed as well as macular thickness in each of the 9 sectors defined by the software. Results. The mean signal strength was significantly lower in the KC group (mean 8.4, range 6–10) compared with the control group (mean 9.7, range 7–10), P < 0.0001 (unpaired t-test). There were no significant differences in cube volume (unpaired t-test), cube average thickness, or macular thickness between the KC group and the control subjects in any of the retinal locations (one-way ANOVA). Conclusion. Macular structure as measured by OCT in KC subjects should be expected to lie within the range of age and sex matched controls.

“…Although the postoperative 1st, 3rd and 6th month central macular thickness values were higher than the pre-operative values in both groups, but this increases was not statistically significant. The authors believed that the lack of a significant difference between the two groups although DALK was performed in a closed system were due to the fact that the big-bubble technique can disrupt the blood-retina barrier as much as PK and the long duration of DALK surgery (16).…”

Aim: To evaluate the changes in central macular thickness after penetrating keratoplasty. Material and Methods: A total of 24 eyes of 24 patients who had undergone penetrating keratoplasty were included in the study. This study was performed retrospectively by reviewing the charts of the patients. Postoperative 1st week, 1st month, 3rd month, 6th month and 12th month mean total macular volume, central macular thickness, parafoveal area and perifoveal area thickness and retinal nevre fiber layer (RNFL) thickness results obtained with optic coherence tomography were compared. ANOVA test was used for statistical analysis. Results: The postoperative 1st week, 1st month, 3rd month, 6th month and 12th month mean total macular volume measurements were 7.03±0.2 mm³, 7.05±0.4 mm³, 7.0±0.6 mm³, 7.02±0.5 mm³ and 6.12±0.6 mm³, respectively. Mean central macular thickness measurements were 227.6±4.6 μm, 228.7±5.5 μm, 227.2±4.6 μm, 227.5±7.1 μm, 226.3±5.1μm respectively; mean parafoveal area thickness measurements were 290.2±3.7 μm, 289.9±7.8 μm, 288.7±6.3 μm, 288.8±4.7 μm, 288.6±8.3 μm respectively, mean perifoveal area thickness measurements were 261.1±4.2 μm, 261.4±1.9 μm, 260.4±3.6 μm, 259.8±2.7 μm, 259.3±4.7 μm respectively, and mean RNFL thickness measurements were 106.54±11.28 μm, 107.28±8.75 μm, 107.45±13.64 μm, 105.62±9.27 μm, 105.16±12.74 μm; respectively. Conclusion: No significant change was seen in macular thickness after penetrating keratoplasty. Although the macular thickness increases in the early postoperative stage, it decreases in time.

Changes in Central Macular Thickness After Uncomplicated Corneal Transplantation for Keratoconus: Penetrating Keratoplasty Versus Deep Anterior Lamellar Keratoplasty

Abstract: The study showed that DALK, although it is a closed-system technique, has a similar impact on the macula compared with PKP.
