Background: Retinal detachments induced by cytomegalovirus (CMV) retinitis can often be treated successfully with a buckling procedure combined with vitrectomy and silicone oil instillation, but this technique yields varying visual results.
Methods: To minimize operational trauma, pars plana vitrectomy and silicone oil instillation without additional buckling was performed in a series of 11 consecutive patients with acquired immune deficiency syndrome (AIDS) and CMV-retinitis-induced retinal detachment. Surgery was performed early in the course of the retinal detachment: 6 patients (55%) had an attached macula, and 7 patients (64%) had a visual acuity of 20/200 or better.
Results: After a mean follow-up period of 5 months (range, 1-9 months) 9 patients (82%) had a completely reattached retina and 9 patients (82%) had visual acuity of 20/200 or better. The macula was reattached in all patients. A localized detachment of the inferior retina was noted in 2 patients (18%), and a second operation was required in one eye. Significant cataract formation occurred in two patients during the follow-up period. Proliferative vitreoretinopathy and increased intraocular pressure were not observed.
Conclusion: Early vitrectomy without additional buckling procedures is justified in patients with CMV-associated retinal detachment because it stabilizes the retinal situation without major complications and improves visual function.

Background: Lens implantation becomes a major concern in patients lacking posterior capsular support, but various methods are available for rehabilitation. In such patients, scleral-fixated intraocular lens (SFIOL) implantation is preferred due to its fewer complications and better simulation of the natural lens position. In this non-randomized retrospective clinical study, we aimed to assess visual outcomes after sutureless SFIOL implantation in aphakic patients and factors affecting visual outcomes.

Emory Eye Center, Emory University, Atlanta, GA, USA.
Purpose: To report a case of persistent bilateral sclerouveitis following bilateral bimatoprost implantation (Durysta) that required implant removal and oral steroid course.
Observation: A 75-year-old Caucasian male with no prior ocular inflammation experienced bilateral sclerouveitis post bilateral bimatoprost implantation. Despite implant removal from both eyes, the ocular inflammation persisted, showing cystoid macular edema in both eyes and exudative retinal detachment in the right.

Dept. of Retina and Vitreous, Narayana Nethralaya, #121/C, 1st R Block, Chord Road, Rajaji Nagar, Bengaluru, 560010, India.
Purpose: To report a rare case of a Coats-like response developing after vitreoretinal surgery for proliferative diabetic retinopathy (PDR) and its successful management with retinal laser photocoagulation and adjunctive intravitreal steroids.
Case Description: A 52-year-old woman with a five-year history of type 2 diabetes mellitus and hypertension presented with decreased vision in the left eye (counting fingers at 1 m). Examination revealed high-risk PDR in both eyes, with a subtotal macula-off combined retinal detachment in the left eye.
Hereditary Vitreoretinopathies: Molecular Diagnosis, Clinical Presentation and Management.

Hereditary vitreoretinopathies (HVRs), also known as hereditary vitreoretinal degenerations comprise a heterogeneous group of inherited disorders of the retina and vitreous, collectively and variably characterised by vitreal abnormalities, such as fibrillary condensations, liquefaction or membranes, as well as peripheral retinal abnormalities, vascular changes in some, an increased risk of retinal detachment and early-onset cataract formation. The pathology often involves the vitreoretinal interface in some, while the major underlying abnormality is vascular in others. Recent advances in molecular diagnosis and identification of the responsible genes and have improved our understanding of the pathogenesis, risks and management of the HVRs.
