ABSTRACT
We report a rare case of bilateral spontaneous anterior partial in‑the‑bag intraocular lens (IOL) dislocation in a 75‑year‑old man with pseudoexfoliation (PXF). He underwent uneventful phacoemulsification in both eyes with in‑the‑bag IOL implantation 9 years back. In the right eye, single piece poly (methyl methacrylate) (PMMA) IOL (+19 D) and in the left eye, single piece acrylic foldable IOL (+19 D) were implanted. An attempt at pharmacological IOL repositioning was unsuccessful. The dislocated IOLs were explanted and exchanged with scleral suture fixated PMMA IOLs. Vision improved to 20/30 in both eyes following surgery, without any associated ocular morbidity. We believe that zonular weakness secondary to PXF, capsular contraction, and myopia together were the predisposing factors for partial anterior dislocation of IOLs and IOL exchange with scleral suture fixation of IOL is a safe and effective treatment option.
ABSTRACT
An 18-year-old woman was referred with late sequelae of chloroquine-induced Steven–Johnson syndrome. At the time of presentation, the symblepharon was involving the upper lids to almost the whole of the cornea, and part of the lower bulbar conjunctiva with the lower lid bilaterally. Other ocular examinations were not possible due to the symblepharon. B-scan ultrasonography revealed acoustically clear vitreous, normal chorioretinal thickness, and normal optic nerve head, with an attached retina. Conjunctivo-corneal adhesion released by superficial lamellar dissection of the cornea. Ocular surface reconstruction was carried out with a buccal mucous membrane. A bandage contact lens was placed over the cornea followed by the symblepharon ring to prevent further adhesion. The mucosal graft was well taken up along with corneal re-epithelization. Best corrected visual acuity of 20/120 in both sides after 1 month and 20/80 after 3 months was achieved and maintained till the 2.5-year follow-up.

An 18-year-old boy presented to us with bilateral retinal hemangioblastoma and von Hippel-Lindau disease with history of cerebral capillary hemangioblastoma and embryonic cell carcinoma of left testes. The vision in the right eye was already lost with development of secondary closed angle glaucoma, optic atrophy with subsequent development of bullous keratopathy. The multiple retinal angiomatous lesions in the seeing left eye were treated with various modalities like triple freeze thaw cryopexy, focal lasers and transpupillary thermo therapy in multiple sittings over a period of almost 20 years since detection. One particular angiomatous lesion in the left eye was showing resistance to all the above mentioned modalities and was finally successfully treated with verteporfin and photodynamic therapy to achieve complete regression without any post-treatment complication and with a sustained 20/20 vision till a follow-up of 15 months.

Phacoemulsification with implantation of single-piece acrylic foldable intraocular lens (IOL) in a 19-year-old boy with microspherophakia, high myopia and angle closure glaucoma is described. The associated myopia and angle closure glaucoma was severely compromising the quality of life. Post-surgical visual recovery was 20/20 with sustained normal intraocular pressure. Management of such cases at times calls for innovations in current surgical technique.

Purpose: To investigate the association of posterior indirect traumatic optic neuropathy and superior temporal orbital rim injury in two-wheeler riders and documentation of the clinical profile of such cases. Design: Retrospective observational study. Materials and Methods: Records of all patients reporting with cranio-orbital injury and vision loss following road traffic accidents between October 1994 and April 2006 were reviewed and from them cases with vision loss solely from indirect optic nerve injury were taken up for study. The prognostic significance of different presenting features, role of intravenous methyl prednisolone (IVMP) and relative risk of superior orbital rim injury to posterior indirect traumatic optic neuropathy (at 95% confidence interval) was calculated. Results: Out of 129 consecutive cases of cranio-orbital injury, 35 had posterior indirect traumatic optic neuropathy with minor ipsilateral superior temporal orbital rim trauma and none used any protective headwear. Presenting clinical features like relative afferent pupillary defect ( P = 0.365), optic disc status ( P = 0.518) and visual evoked potential (VEP) ( P = 0.366) were disproportionate to visual loss. Only VEP had prognostic significance. The IVMP did not provide any added therapeutic benefit. The remaining 94 cases sustained direct blinding ocular trauma and 28 of them had associated intracranial pathology. The relative risk of superior temporal orbital rim injury to posterior indirect optic nerve trauma was 2.25. Conclusion: Superior temporal orbital rim injury, even when minor, carries a potential risk for development of blindness from indirect posterior indirect traumatic optic neuropathy in two-wheeler drivers. Presenting signs do not correlate with visual status. Only VEP has prognostic significance and the condition is untreatable.
ABSTRACT
Descemet's membrane detachment is a condition with a wide range of etiologies. The most common cause is a localized detachment occurring after cataract surgery. We report a case of vancomycin injection-induced Descemet's membrane detachment as a complication following a routine cataract surgery and its management.

A carotid-cavernous fistula (CCF) is an abnormal communication between the cavernous sinus and the carotid arterial system. A CCF is divided into two categories, direct and indirect. Direct fistulas usually account for 70 to 90% of all CCF. Spontaneous, low-flow fistulas are usually associated with atherosclerosis, hypertension and collagen vascular disease or may develop in females during peripartum period. The elderly age group, especially women are at increased risk. We report three cases of spontaneous CCF presenting with ocular manifestations and hypertension, without any collagen vascular disease. One case was a direct variety and the other two were of indirect variety.
