Purpose: To describe short term outcomes in a case series of infants with rapidly progressive retinopathy of prematurity (ROP) requiring laser and lens-sparing vitrectomies (LSV) at early postmenstrual ages (PMAs).
Methods: Retrospective chart review of infants born at or under 24 0/7 weeks consecutively referred for management of severe ROP between August 2006 and January 2007.
Results: Five female infants (mean gestational age 23 4/7 weeks, mean birthweight 514.4 g) required laser treatment bilaterally for zone 1 or posterior zone II ROP at 35-37 weeks PMA. LSV was performed for progressive stage 4 ROP in eight eyes at 37-39 weeks PMA (mean 38.2 weeks). Subretinal hemorrhage occurred after LSV in five eyes, with three developing subretinal fibrosis preventing complete retinal reattachment.
Conclusion: Premature infants in this series had rapidly progressive ROP requiring laser and LSV at early PMAs. Subretinal hemorrhage occurred and may be related to the amount of laser necessary to treat large zones of avascular retina, and the early timing of vitrectomy when postoperative contracting preretinal vitreous no longer has the natural tamponading force of formed gel against it. Improved therapies for premature infants of very young gestational ages and large avascular zones are needed.

Delayed Sensory Exotropia With Retained Metallic Intraorbital Foreign Body.
J Pediatr Ophthalmol Strabismus
January 2025
This report describes the longest case of a retained metallic intraorbital foreign body with no complications and development of delayed sensory exotropia following traumatic sclopetaria in childhood. A 9-year-old girl suffered a BB gun injury to the left eye, leading to chorioretinitis sclopetaria and loss of vision. The visual acuity was 20/800 with a relative afferent pupillary defect and choroidal rupture with subretinal hemorrhage that evolved to sclopetaria over time.

January 2025
Background And Objective: To assess the efficacy of intravitreal aflibercept 8 mg in treating neovascular age-related macular degeneration (nAMD) in patients previously treated with faricimab.
Patients And Methods: A retrospective study was conducted on nAMD patients with suboptimal response to faricimab injections who were switched to intravitreal aflibercept 8 mg. Visual acuity (VA) and optical coherence tomography features were evaluated.
Orbital and Ocular Venous Congestion: A Rare Manifestation of Hypervascular Paget Disease of the Bone.
Ophthalmic Plast Reconstr Surg
January 2025
Department of Ophthalmology, Massachusetts Eye and Ear, Harvard Medical School, Boston, Massachusetts.
A 73-year-old male with a history of incidentally diagnosed Paget disease of bone affecting the skull and left orbit 2 years prior presented with 3 months of vision loss, proptosis, and periorbital swelling of the OS. Examination showed best-corrected Snellen visual acuity of 20/150 in the affected eye, intact motility, 7 mm of relative proptosis, significant dilated and tortuous "corkscrew" conjunctival vessels, serous choroidal and retinal detachments, optic nerve hyperemia, and venous tortuosity and dilation. Although the bony lesions in the left orbit were stable from 1 year prior on imaging, the diagnostic angiogram demonstrated osseous blush and hypervascularity of the lesion.

Retina
February 2025
Disha Eye Hospitals Pvt Ltd, Barrackpore, India.
Purpose: To develop a simple tool to remove retained submacular perfluorocarbon liquid bubbles (R-PFCL) and to inject recombinant tissue plasminogen activator safely in subretinal space in submacular hematomas.
Method: A retrospective, interventional study was performed where a simple homemade micro-viscous fluid control was developed to gain access to subretinal space in a controlled way. The rubber cap of the plunger of a 1-mL syringe was cut; this cut rubber cap of the plunger was fitted inside an empty 1-mL tuberculin syringe, and its end was fitted with the tubings of viscous fluid control of the vitrectomy machine.
An atypical case of retinal pigment epithelium tear with remodeling and visual preservation.

Singapore Eye Research Institute, Singapore National Eye Centre, Singapore.
This report describes a patient with polypoidal choroidal vasculopathy (PCV) with fovea-involving retinal pigment epithelium (RPE) tear that showed tissue remodeling with a good visual outcome. Imaging over the patient's clinical course from 2019 was reviewed. A 74-year-old female presented with left submacular hemorrhage and a large multi-lobular pigment epithelial detachment.
