The incidence of ERM after pars plana vitrectomy alone for the repair of primary pseudophakic or aphakic rhegmatogenous retinal detachment was similar to reported incidences after scleral buckling. Best-corrected visual acuity improved after surgical removal of ERM, although eyes with the macula detached had lower final BCVA.

Aims: To report the management of vision-threatening complications of vasoproliferative tumors of the retina. Methods: Clinical records of 31 eyes of 30 patients treated at our centers from 1998 through 2013 were reviewed. The main outcome measures included: type of treatment, tumor regression, tumor relapse and final visual acuity. Results: Seventeen patients (57%) underwent vitrectomy for epimacular membranes (n = 10), rhegmatogenous retinal detachment (n = 2), vitreous hemorrhage (n = 2), tractional retinal detachment (n = 1), serous retinal detachment (n = 1) and subhyaloid hemorrhage (n = 1). After the initial treatment, 10 additional surgeries were performed for vitreoretinal complications. Tumor activity was treated in all eyes either with photocoagulation or cryotherapy. Control of tumor activity was achieved in all cases, after treatment of recurrences. There were no statistically significant differences between initial and final visual acuity (p = 0.437). Recurrence showed a statistically significant association with the presence of proliferative vitreoretinopathy (p = 0.024), tumor thickness (p = 0.026), basal diameter (p = 0.031), and use of photocoagulation alone as initial treatment (p = 0.006, logistic regression). Conclusion: In our series, more than half of vasoproliferative tumors of the retina required surgery as the initial treatment. Recurrence was associated with tumor size, presence of proliferative vitreoretinopathy, and use of photocoagulation alone as the initial treatment.

In our series, patients with syphilitic uveitis were more usually middle-aged men and were frequently co-infected with HIV. Although most patients showed posterior segment involvement, visual prognosis was good.

PurposeTo evaluate the long-term cumulative probability of intraocular pressure (IOP) elevation with the intravitreal dexamethasone implant (IDI) when used to treat different indications: diabetic macular edema, uveitis, retinal vein occlusion.Methods705 IDI injections (429 eyes) were assessed and Kaplan-Meier graphs were generated to assess: the probability of different levels of IOP elevation (IOP≥21, ≥25 or ≥35 mmHg), IOP change ≥10 mmHg, initiation of IOP-lowering treatment, glaucoma surgery, IOP change with repeat injections and IOP elevation in eyes with glaucoma and ocular hypertension (OHT).ResultsThe cumulative probability of IOP ≥21, ≥25 and ≥35 mmHg was 50%-60%, 25%-30% and 6%-7% at 12–24 months, respectively. The probability of initiating IOP-lowering medication was 31%-54% at 12–24 months. Glaucoma and OHT eyes had a higher probability of mild IOP elevation (≥21 mmHg, 65.1%, 75% and 57.8%, p = 0.01), yet a similar moderate (≥25 mmHg, 22.3%, 28% and 30.2%, p = 0.91) and severe elevation of IOP (≥35 mmHg, 3.7%, 7.1% and 4%, p = 0.71) as normal eyes. Glaucoma surgery was required in only 0.9% cases (4/429). At baseline, 8.8% of the treated eyes had glaucoma, 6.7% OHT and 16.9% were already on IOP-lowering medication.ConclusionsIn the long-term (24 months), IOP elevation is common, generally mild (30% IOP, ≥25 mmHg) and well-tolerated, resolving with topical treatment (54%) and rarely requiring surgery (0.9%).

Diabetic macular edema (DME) is the most common cause of vision loss in diabetic patients. Thirty years ago, the Early Treatment Diabetic Retinopathy Study (ETDRS) demonstrated that focal/grid laser photocoagulation reduces moderate vision loss from DME by 50% or more; thus, macular photocoagulation became the gold standard treatment for DME. However, with the development of anti-VEGF drugs (bevacizumab, ranibizumab, and aflibercept), better outcomes were obtained in terms of visual acuity gain and decrease in macular thickness in some studies when antiangiogenic drugs were administered in monotherapy. Macular laser therapy may still play an important role as an adjuvant treatment because it is able to improve macular thickness outcomes and reduce the number of injections needed. Here, we review some of the clinical trials that have assessed the efficacy of macular laser treatment, either as part of the treatment protocol or as rescue therapy.
