Purpose: Severe trauma of the viscerocranium or neurocranium may result in impaired visual acuity or even blindness. Case based epidemiology, pathomechanism and actual strategies in midfacial trauma for initial therapy and prevention of posttraumatic blindness are discussed.
Case And Review: A 58-year old patient was treated at our Department of Oral and Maxillofacial Plastic Surgery after his central midface had been hit by a swinging steel girder. Initially he was blind on both eyes. Initial treatment started by applying 24 mg of dexamethasone and omeprazole. During the following 2 weeks, amaurosis persisted on the left eye. On the right eye complete visual acuity was regained. On the basis of data from our Department of Oral and Maxillofacial Plastic Surgery an Odds Ratio of 0.12 was calculated for the combination of blindness and midfacial trauma. Today cortisol therapy is still used. However, hypothermia, anti-Trendelenburg position, and application of mannitol seem to be more effective therapeutic strategies. Erythropoetine and progesterone are promising drugs with neuroprotective, anti-inflammatory as well as anti-oedematous effects.
Conclusion: The risk of blindness is higher than expected. Latest findings regarding the neuroprotective effects of erythropoetine or/and progesterone seem to promise a more successful treatment.

Although silicone oil is used as an intraocular buffer in vitreoretinal surgical procedures, its use can cause complications, including glaucoma. This study highlights the importance of individualized approaches for the management of silicone oil-induced glaucoma. A 62-year-old man with a past medical history of retinal detachment and multiple ocular surgical procedurespresented with uncontrolled ocular pressure peaks after retinal detachment surgery using silicone oil as a buffer, which did not resolve after removal of the buffer.

The aim of this article has been, on the one hand, to describe the use of MSICS (manual small incision cataract surgery) for the management of cataracts, especially mature ones, in relation to its particular utility in the field of humanitarian campaigns, for which a description of the MSICS technique has been made, subsequently a review of the available scientific literature has been carried out to verify the results of this technique in comparison with phacoemulsification and extracapsular surgery and to describe the importance of teaching this technique to all cataract surgeons, especially the ones participating in humanitarian campaigns. According to what has been found, MSICS is an excellent surgical technique and according to current evidence it seems to be the choice over phacoemulsification and/or the classic extracapsular technique in hyper mature cataracts, especially in the field of humanitarian campaigns, due to its lower rate of complications and the improvement in visual acuity obtained. According to the studies found, it would be possible for the experienced ophthalmologic surgeon to implement this technique since the learning curve is short.

Background: This study investigated the association between photoreceptor structural restoration and visual function outcomes in patients undergoing surgery for closed macular holes (MHs). Using adaptive optics scanning laser ophthalmoscopy (AOSLO) and microperimetry, we aimed to provide a more detailed understanding of photoreceptor recovery and visual improvement in closed MHs.
Methods: We conducted a retrospective observational study of 31 eyes of 28 patients who underwent vitrectomy with internal limiting membrane (ILM) peeling to treat idiopathic MHs.

Introduction: Tumorous growths in the sellar region pose significant clinical challenges due to their proximity to critical visual structures such as the optic chiasm and optic nerves. Given their proximity to the optic system, these tumors are often diagnosed due to a progressive decrease in visual acuity. Thus, surgical intervention is crucial to prevent irreversible damage, as timely decompression can halt the progression of edema and subsequent optic atrophy.

Background: We aimed to describe a 2-year outcome of eyes managed by practitioners benchmarked using a funnel plot by their frequency of treatment using vascular endothelial growth factor (VEGF) inhibitors for naive retinal vein occlusion (RVO).
Methods: A multicentre, international, observational study of 29 doctors in 12 countries managing 1110 eyes with RVO commencing VEGF inhibitors between 1 January 2012-2022 tracked in the Fight Retinal Blindness! registry.
Results: We identified 3 outlying 'intensive' practitioners (managing 350/1110 eyes [32%]), 22 'typical' practitioners (604/1110, [54%]) and 4 outlying 'relaxed' practitioners (156/1110, [14%]) with respective 24-month outcomes in Branch and Central RVO including the primary outcome, mean adjusted change in visual acuity (VA) in BRVO: +16.
