Visual acuity, cycloplegic refraction, contrast sensitivity, stereopsis, intraocular pressure (IOP), vaulting, corneal endothelial cell count and complications were evaluated. Patients completed follow-up at 3d, 1, 3mo and the last follow-up time (mean 8.18±2.82mo) after surgery.RESULTS: The mean myopic anisometropia was -13.70±3.25 D preoperatively and +0.69±2.63 D at 8mo postoperatively. The logMAR corrected distance visual acuity (CDVA) of the amblyopic eye was 1.51±0.72 preoperatively and 0.75±0.40 at 8mo postoperatively. The logMAR CDVA at 3d, 1, 3 and 8mo postoperatively improved by a mean of 0.64, 1.55, 1.82 and 2.64 lines and gained more than 2 lines accounted for 18%, 45%, 45%, 64%, respectively. The contrast sensitivity of 0.5, 1 and 2 cpd in amblyopic eyes was significantly increased after surgery. No patient had near stereopsis recovery. The vaulting at 3 and 8mo was significantly lower than that at 1mo postoperatively. No other intraoperative or postoperative complications were observed, except an acute pupillary block glaucoma happened in a patient at two weeks postoperatively.CONCLUSION: This short-term results indicate that ICL implantation can be a promising alternative therapy for high myopic anisometropic amblyopia in pediatric patients who have failed with conventional treatments and not suitable to corneal refraction surgery.展开更多

The rhegmatogenous form is the most common and its management is exclusively surgical as soon as possible. This urgency becomes major and absolute when it occurs in a particular monocular vision. Purpose: To analyze the clinical forms of rhegmatogenous retinal detachment (RRD), the results and the complications of their management in monophthalmic patients. Methodology: This was a retrospective and analytical study from June 2007 to December 2019. We included all patients who received a consultation for rhegmatogenous retinal detachment. All patients were seen by at least two posterior segment specialists and all were operated on by the same surgeon. Results: 57 files (57 eyes) were collected with an average age of 44.71 years and a sex ratio of 7.14. The average consultation time is 40.80 days. Patients complained of decreased visual acuity in 96.49% of cases. We had myopia in 49.12% of cases and 91.23% of patients were phakic. Retinal holes were found in 31.58% of our patients and giant tears in 17.54%. The mean retinal detachment extension was 2.52 quadrants and the macula was raised in 32 cases. The average time taken to take charge was 10 days. Detachment surgery was performed in 42 patients with 100% anatomical recovery. Conclusion: Retinal detachment in one-eyed patient is a major ophthalmic emergency. Its management must not suffer from any delay. Post-operative outcomes are relatively similar between the internal and external pathways. In one-eyed patient, silicone can be left alone in the absence of complications.展开更多
