Modified Anterior Lamellar Recession for All Grades of Upper Eyelid Trachomatous Cicatricial Entropion.

Purpose: This study aims to assess the combination of anterior lamellar recession (ALR) with blepharoplasty, suprasternal fixation, and internal eyelash bulb extirpation of aberrant lashes posteriorly located in patients with any grade of upper eyelid trachomatous cicatricial entropion. Patients and Methods: We reviewed the clinical data of eighty-six patients (143 eyelids) including age, gender, systemic medical illnesses, and comprehensive ophthalmological assessment. Eyelid evaluation was recorded, including laterality, previous surgical technique used, possible trichiasis etiology, abnormality of the lid margin, tarsal plate consistency (shrinkage or loosening), skin fold overhanging, laxity of the pretarsal skin, margin reflex distance 1 (MRD1), lagophthalmos, and lid retraction. The success rate was assessed at 3, 6, 9, and 12 months postoperative. Results: The success rate was 97.2% in the third month, which decreased significantly to 92.3% in the 6th month and 90.2% in the 9th month (P = 0.01, and 0.001 respectively). In the 9th month, we had fourteen failed cases. All of them were submitted for a second intervention. Three underwent electrolysis, four cases underwent re-internal bulb extirpation, four cases underwent the same procedure, and three cases underwent epilation. The success of the failed cases after the second intervention was significantly associated with the type of reintervention (P = 0.03), in which all of them succeed except two cases that underwent epilation. Kaplan-Meier analysis showed that the mean recurrence time in our study was 6.8 months (95% CI = 5.8-7.7 months). Conclusion: This study showed the combination of ALR with blepharoplasty, suprasternal fixation, and cauterization or internal bulb extirpation of posteriorly located lashes procedure resulted in a high success rate in patients with any form of UCE with no increase in incidence or degree of lagophthalmos associated with UCE.

Evaluation of Higher Order Aberrations and Anterior Segment Parameters Changes After Implantable Collamer Lens Implantation for High Myopia.

Purpose: To evaluate changes in higher order aberrations (HOAs) induced by implantable collamer lens (ICL) implantation in correction of high myopia and to compare the anterior segment parameters before and after surgery. Also, to correlate these parameters with HOAs, the best corrected visual acuity (BCVA) and intraocular pressure (IOP). Methods: This prospective interventional cohort case series study included 40 eyes with high myopia that underwent ICL V4c implantation. They were evaluated pre-operatively and post-operatively at 1st and 3rd month HOAs using Scheimpflug Sirius Camera. The anterior segment parameters were evaluated by optical biometry. Correlations between HOAs, BCVA and anterior segment parameters were evaluated. Results: The mean pre-operative BCVA was 0.67 ± 0.17, while post-operative BCVA was 0.74 ± 0.16 (p-value < 0.001). The spherical equivalent was -13.66 ± 2.23 pre-operatively, while post-operatively it was -0.77 ± 0.65 (p-value < 0.001). The mean pre-operative root mean square (RMS) of HOAs was 0.62 ± 0.11 µm, while mean post-operative RMS in the 1st month was 0.82 ± 0.29 µm (p-value < 0.001). At 3rd month, it was 0.63 ± 0.17 µm (p-value = 0.685). The mean pre-operative anterior chamber depth (ACD) was 3.66 ± 0.26 mm. It decreased in the post-operative 1st month to 3.46 ± 0.30 mm, while in 3rd month 3.45 ± 0.24 mm (p-value < 0.001, < 0.001) respectively. The mean pre-operative anterior chamber angle (ACA) 45.98 ± 8.39 o while, the mean ACA was 31.65 ± 4.14, 31.03 ± 3.74 post-operatively (p-value < 0.001, < 0.001) respectively. There was significant increase in IOP (p-value < 0.001). Conclusion: ICL implantation is safe and effective in correction of high myopia, as HOAs increase at first month post-operatively then, return to the pre-operative level by 3rd month. However, anterior segment parameters show significant changes which may need longer follow up.

Comparison between intravitreal ranibizumab injection and posterior subtenon triamcinolone acetonide injection at time of cataract surgery for prevention of progression of diabetic macular edema.

BACKGROUND: The goal of this work is to assess progression of diabetic macular edema (DME) following intravitreal ranibizumab injection compared to subtenon triamcinolone acetonide injection at cataract operation. METHODS: Retrospective analysis of 73 eyes of 65 participant with DME, with central macular thickness (CMT) ≥ 300 µm. The included eyes were separated into three groups; phacoemulsification with intravitreal Ranibizumab injection group, phacoemulsification with subtenon Triamcinolone acetonide injection group and phacoemulsification only group. Main measures involved best corrected visual acuity (BCVA) one week, one month and three months post-operative. The CMT was compared preoperative and postoperative (one and three months). RESULTS: After 1 month of operation, there was a statistical substantial distinction in the median of CMT between ranibizumab & control group (p < 0.001), between subtenon TA & control group (p < 0.001) and in ranibizumab and subtenon TA group (p = 0.023). After 3 months, the variance between ranibizumab & control group was considerable (p < 0.0001) and the variance between subtenon TA & control group was considerable (p = 0.030). CONCLUSIONS: Combined phacoemulsification with intravitreal injections of ranibizumab or subtenon triamcinolone acetonide may prevent further progression in CMT in individuals with DME following cataract operation.
