Corneal Topograph-guided Laser Subepithelial Keratomileusis (LASEK)Corrects Decentered Ablation after Laser in Situ Keratomileusis (LASIK): A Case Report
2016Co-Authors: Jing Zhang, Hui Hui LuoAbstract:Purpose:Corneal topograph-guided laser subepithelial keratomileusis (LASEK) can effectively correct decentered ablation occurring post laser in situ keratomileusis (LASIK) and to enhance our understanding and diagnosis of decentered ablation following LASIK. Methods:Previous studies in the relevant literature are reviewed, and a case report is provided. Results:A patient with high myopia undergoing LASIK in both eyes presented with Distorted Vision in the left eye, which interfered with the Vision in the right eye and caused blurred Vision in both eyes. The patient was unable to see objects with both eyes. After receiving corneal topography-guided LASEK,the signs of Distorted Vision in the left eye and bilateral blurred Vision were significantly alleviated,and the patient could see objects with both eyes simultaneously. Conclusion: Clinical ophthalmologists should be aware of the occurrence of decentered ablation after LASIK. Corneal topography-guided LASEK is an efficacious tool for correcting decentered ablation.

Etiology and Management of Branch Retinal Vein Occlusion
2009Co-Authors: Sadaf Hamid, Sajid Ali Mirza, Ishrat Shokh, B Shahra-e-ghalibAbstract:Retinal vein occlusion is one of the vascular disorders affecting Vision. Branch retinal vein occlusion and central retinal vein occlusion are the two basic types of vein occlusion. Branch retinal vein occlusion is three times more common than central retinal vein occlusion and is second only to diabetic retinopathy as the most common retinal vascular cause of visual impairment. The origin of branch retinal vein occlusion includes systemic factor-hypertension and local anatomic factor-arteriovenous crossings. Branch retinal vein occlusion results in misty or Distorted Vision. Retinal vein occlusion is a multifactor process. There is no single magic bullet that cures retinal vein occlusion. A comprehensive management of patients with retinal vein occlusion is necessary to correct associated diseases or predisposing abnormalities that could lead to local recurrences or systemic event. This paper reviews the etiology and treatment of retinal vein occlusion and recommends the collaboration between other branches for its management.

Branch retinal vein occlusion.
Journal of Ayub Medical College Abbottabad, 2008Co-Authors: Sadaf Hamid, Sajid Ali Mirza, Ishrat ShokhAbstract:Retinal vein occlusions (RVO) are the second commonest sight threatening vascular disorder. Branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO) are the two basic types of vein occlusion. Branch retinal vein occlusion is three times more common than central retinal vein occlusion and- second only to diabetic retinopathy as the most common retinal vascular cause of visual loss. The origin of branch retinal vein occlusion undoubtedly includes both systemic factors such as hypertension and local anatomic factors such as arteriovenous crossings. Branch retinal vein occlusion causes a painless decrease in Vision, resulting in misty or Distorted Vision. Current treatment options don’t address the underlying aetiology of branch retinal vein occlusion. Instead they focus on treating sequelae of the occluded venous branch, such as macular oedema, vitreous haemorrhage and traction retinal detachment from neovascularization. Evidences suggest that the pathogenesis of various types of retinal vein occlusion, like many other ocular vascular occlusive disorders, is a multifactorial process and there is no single magic bullet that causes retinal vein occlusion. A comprehensive management of patients with retinal vascular occlusions is necessary to correct associated diseases or predisposing abnormalities that could lead to local recurrences or systemic event. Along with a review of the literature, a practical approach for the management of retinal vascular occlusions is required, which requires collaboration between the ophthalmologist and other physicians: general practitioner, cardiologist, internist etc. as appropriate according to each case.

Multimodal imaging for detecting metamorphopsia after successful retinal detachment repair
Graefe's Archive for Clinical and Experimental Ophthalmology, 2020Co-Authors: Megir Schawkat, Christophe Valmaggia, Corina Lang, Hendrik Pn Scholl, Josef GuberAbstract:Purpose To investigate the etiologies of metamorphopsia after successful retinal detachment repair. Methods In this retrospective study, we included patients who underwent pars plana vitrectomy (PPV) for macula-off rhegmatogenous retinal detachment (RRD). Patients were reviewed after 3 to 6 weeks. Best-corrected visual acuity (BCVA), fundus biomicroscopy, Amsler grid test, spectral-domain optical coherence tomography (SD-OCT), and fundus autofluorescence images (FAF) were obtained from all patients to visualize abnormalities in retinal layers and retinal rotation. Results A total of 50 eyes from 49 consecutive patients were included, of whom 12 (24%) complained of postoperative metamorphopsia. The main cause of metamorphopsia was retinal shift after RRD repair ( p < 0.001). Conclusion Distorted Vision after macula-off RRD is a common and retinal shift was found to be the main reason patients experience metamorphopsia after a successful macula-off RRD repair.

How to Prevent Retinal Shift after Rhegmatogenous Retinal Detachment Repair: A Prospective, Randomized Study.
Ophthalmology Retina, 2019Co-Authors: Josef Guber, Megir Schawkat, Corina Lang, Hendrik Pn Scholl, Christophe ValmaggiaAbstract:Purpose To evaluate the effect of intraoperative use of heavy liquid on retinal shift after retinal detachment repair. Design Prospective, randomized study. Participants Patients who underwent pars plana vitrectomy for macula-off rhegmatogenous retinal detachment were included in the current study. Methods Patients were randomized into 2 groups: group A included patients in whom heavy liquid was used during the procedure and group B included patients in whom no heavy liquid was used. Group A and B patients were reviewed after 3 weeks and after 6 weeks, respectively, and fundus autofluorescence (FAF) images were obtained to visualize the retinal rotation. Main Outcome Measure Postoperative macular shift, visualized with FAF. Results A total of 50 eyes from 49 patients were included. Overall, retinal shift was observed in 17 patients (34%). Patients in whom heavy liquid was used during the procedure showed significantly less macular shift after surgery (P = 0.049). There was a strong association between retinal shift and postoperative symptoms of metamorphopsia. Ten of 17 patients with retinal shift reported Distorted Vision (P Conclusions The use of intraoperative heavy liquid seems to be associated with lower occurrence of retinal shift after retinal detachment repair.
