(29) This is of particular concern as eyes with increased axial length and deformation of the posterior segment can lead to several lesions including myopic choroidal neovascularisation, lacquer cracks, chorioretinal atrophy, posterior staphyloma and macular retinoschisis.
1 case (2%) ended in perforation underwent Therapeutic penetrating keratoplasty, 3 cases (6%) lead to panophthalmitis and 1 case (2%) resulted in anterior staphyloma. Out of 3 panophthalmitis cases 1 was positive for Aspergillus, 1 was for S.aureus on culture and 1 was no growth.
The main findings in the anterior segment of patients without ocular TB were conjunctivitis (9.8%), followed by pterygium, and blepharitis, while in the posterior segment were staphyloma and glaucomatous excavation.
The pathological changes include posterior scleral staphyloma, choroidal neovascularization, retinal choroidal atrophy, streak, and peripheral retinal degeneration [8, 9].
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.

Detailed examination revealed corneal ulceration, oedema and protruding of iris through a full thickness wound on cornea in both cases and was diagnosed as staphyloma. Under general anaesthesia, surgical correction was resorted to.
Posterior staphyloma in oculocutaneous albinism: Another possible cause of reduced visual acuity.
The axial length, IOP, posterior staphyloma, and chorioretinal atrophy significantly represent addition ocular factors affecting peripapillary choroidal thickness [19].
AL can help in knowing various conditions of the eye like staphyloma, risk of retinal detachment, intraocular lens power calculation before cataract surgery and refractive surgery and risk of choroidal neovascular membrane (CNVM) and predisposition of closed angle glaucoma.
Jamie had progressive myopia (with higher myopia in her right eye), staphyloma, and a tilted optic disc in her right eye; hypoplasia (in both eyes); nystagmus; and probable ocular motor apraxia.
