Patients with history of hypertension or diabetes, confounding ocular disease, additional eye operations, including vitreoretinal or cataract surgery or refractive surgeries, and other myopic complications (including lacquer cracks, posterior staphyloma, choroidal atrophy, choroidal neovascularization, subretinal hemorrhage, macular traction, macular hole, retinal detachment, and retinoschisis) were excluded.
To explore the presentation of high myopia without complications or myopic maculopathy, lacquer cracks, and posterior staphyloma that can change the choroidal morphology, any instances of amblyopia, eyes with a history of retinal detachment, scleral buckling, pars plana vitrectomy, photodynamic therapy, antivascular endothelial growth factor therapy, macular hole, epiretinal membrane, vitreomacular traction syndrome, foveoschisis, diabetes, any type of glaucoma, or posterior uveitis were excluded.
These include increased vitreous traction due to posterior staphyloma, reduced chorioretinal adhesion due to posterior chorioretinal atrophy, stiffening of the internal limiting membrane (ILM), increased tension in retinal vessels, and tangential forces created by increased cortical vitreous contractions.
Inaccuracies in axial length may be due to presence of posterior staphyloma and poor fixation from macular diseases.
Staphyloma can be associated with epidermal nevus syndrome and MRCS (microcornea, rod-cone dystrophy, cataract, and posterior staphyloma).
Patient age, degree of myopia, axial length, and the presence of a posterior staphyloma (a protrusion of the cornea or sclera in the back of the eye) are important factors for the progression of myopic maculopathy, Dr.
The presence of a marked posterior staphyloma in high myopia patients clearly affects the surgical outcomes of MHRD surgeries.
(2) Other ocular features of familial microspherophakia are lenticular myopia, posterior staphyloma, myopic crescent, ectopic pupil, glaucoma and retinal detachment.
This figure of 4.4% is equal to the study done by Hanif M, and colleagues which showed the percentage of PVD in mature cataracts to be 4.3% other posterior segment pathologies found through B-scan ultrasonography were asteroid hyolosis in 4 eyes (0.8%), posterior staphyloma in 4 cases [0.8%].
Posterior staphyloma was found in (1.10%) nontraumatic cataract patients, it was more than reported in other studies (0.73%).
This case series concluded that the risk factors for recurrent RD after silicone oil removal from cases of myopic MHRD were high myopia, open flat MH, and large posterior staphyloma. Revision of vitrectomy and S.O re-injection can reattach most of recurrent cases.
