Spontaneous lens capsule rupture can occur in hypermature senile cataract (HMSC) and result in anterior or posterior dislocation of the nucleus or spontaneous resorption with or without an accompanying inflammatory reaction of varying severity. An acceptable visual outcome can be obtained, except in the presence of associated glaucoma or corneal decompensation.

SD-OCT reveals formation of a premacular cavity following laser puncture for premacular hemorrhage in Valsalva retinopathy, which may persist despite successful drainage of blood. This may later result in metamorphopsia in certain patients.

A congenital retinal macrovessel (CRM) is a large retinal vessel, usually a vein, which traverses through the central macula and has large tributaries extending on both sides of the horizontal raphe. In the majority of cases, CRM have no effect on visual acuity, although in rare cases, macular hemorrhage, foveolar cysts, serous macular detachment, and the presence of the anomalous vessel in the foveola can affect vision. We describe a case of CRM with decreased vision secondary to a branch retinal artery occlusion (BRAO). To the best of our knowledge, this association has not been reported previously.

The incidence of endophthalmitis after pars plana vitrectomy is low. Silicone oil is a tamponading agent which has anti-microbial activity. Post-operative endophthalmitis following vitrectomy with silicone oil tamponade has been rarely reported. We describe the case of a young male who underwent pars plana vitrectomy with silicone oil for retinal detachment with a giant retinal tear. He developed a clinical picture suggestive of endophthalmitis on the first post-operative day, and vitreous culture grew multidrug-resistant Pseudomonas aeruginosa. He was treated with intravitreal piperacillin/tazobactam, along with appropriate surgical management. This was followed by resolution of the infection with a remarkable improvement in visual acuity. This is the first case of multidrug-resistant Pseudomonas aeruginosa endophthalmitis following pars plana vitrectomy with silicone oil treated successfully with piperacillin/tazobactam.

A 9-year-old boy presented with a 6-month history of decreased vision in his left eye. The patient's retinal examination was significant for telangiectatic vessels involving the posterior pole and the superior and inferior post-equatorial regions, circinate intraretinal exudation at the macula, and a full-thickness macular hole that was confirmed by optical coherence tomography. Chronic exudation from the anomalous vessels may be involved in the pathogenesis. Full-thickness macular hole formation may occur in conjunction with Coats' disease in children, which has not been reported to date, to the best of the authors' knowledge.

Endophthalmitis following intravitreal dexamethasone (DEX) implant has been rarely reported. This report describes the case of a 70-year-old male who underwent intravitreal DEX implant injection under aseptic conditions, for diabetic macular edema. He developed a clinical picture suggestive of endophthalmitis within 2 weeks of the injection, and vitreous culture grew coagulase negative He was treated with intravitreal antibiotics followed by pars plana vitrectomy and removal of the implant. This was followed by resolution of the infection with a favorable final visual outcome. The challenges faced during surgical management of this case are discussed.
