Giant retinal tears complicated by proliferative vitreoretinopathy (PVR) pose one of the more complex problems in vitreoretinal surgery. The authors developed a technique using perfluoro-octane, a temporary vitreous substitute that is heavier than water, combined with vitrectomy, scleral buckling, fluid-gas exchange, and direct manipulation of the retina to treat these cases. Ten eyes with giant retinal tears and grade D-1 PVR or worse were treated. In all eyes, the retina was successfully reattached at the end of surgery. Nine of the ten retinas remained attached after 6 months of follow-up. Five eyes required a total of six reoperations for epiretinal membrane formation without retinal detachment. The one eye in which the retina did not remain reattached developed severe recurrent PVR and iris neovascularization. Visual acuity improved in 8 of 10 eyes. Final visual acuity was 20/400 or better in 8 of 10 eyes, and 20/80 or better in 4 eyes.

Assessing Surgical Competency Among Fellows in Vitreoretinal Surgery: A Survey of Fellowship Program Directors and Fellows.
Ophthalmol Retina
January 2025
Byers Eye Institute, Stanford University, Palo Alto, CA,. Electronic address:
Purpose: We surveyed vitreoretinal (VR) fellowship program directors (PDs) to elucidate how they assess surgical competency among VR fellows. In addition, we also surveyed fellowship program graduates for the years 2022 and 2023 regarding assessment metrics and tools used during VR fellowship training.

Sudden Vision Loss: A Diagnostic Approach.

Vision loss affects more than 7 million Americans and impacts quality of life, independence, social functioning, and overall health. Common and dangerous conditions causing sudden vision loss include acute angle-closure glaucoma, retinal detachment, retinal artery occlusion, giant cell arteritis, and optic neuritis. Acute angle-closure glaucoma features ocular pain, headache, and nausea; treatment includes pilocarpine eye drops, oral or intravenous acetazolamide, and intravenous mannitol.

African mole-rats (Bathyergidae, Rodentia) are subterranean rodents that live in extensive dark underground tunnel systems and rarely emerge aboveground. They can discriminate between light and dark but show no overt visually driven behaviours except for light-avoidance responses. Their eyes and central visual system are strongly reduced but not degenerated.

- The study investigates risk factors for proliferative vitreoretinopathy (PVR), a common complication after retinal detachment surgery.
- A large patient database was analyzed, identifying systemic (like age, gender, and smoking) and ocular (such as trauma and previous eye conditions) factors that correlate with increased PVR risk.
- The findings emphasize the importance of considering these risk factors in surgical planning and treatment to prevent PVR in patients with retinal detachment.
Optic nerve sheath enhancement on orbital MRI in giant cell arteritis.
Br J Ophthalmol

Medicine - Rheumatology, University of Pennsylvania, Philadelphia, Pennsylvania, USA
Background: Differentiating arteritic anterior ischaemic optic neuropathy (A-AION) due to giant cell arteritis (GCA) from non-arteritic anterior ischaemic optic neuropathy (NA-AION) may pose a diagnostic challenge. Our study aimed to assess the use of standard orbital MRI in distinguishing ocular manifestations of GCA from NA-AION.
Methods: This study included 25 consecutive patients (11 GCA, 14 NA-AION) who underwent contrast-enhanced orbital MRIs within 3 months of symptom onset.
