RESUMO

BACKGROUND: AMD (age-related macular degeneration) is the main cause of central vision loss in the population over 60 years old. AMD does not affect peripheral vision and complete blindness does not occur, instead, central vision is affected both for distance and for near. The purpose of this study is to evaluate the neovascular form of AMD treatment and compare ocular and systemic effects after intravitreal injection of aflibercept, respectively after bevacizumab when administered in comparable dosages and regimens. We conducted a retrospective, single-center study from June 2021 to December 2022 and enrolled 20 patients with neovascular AMD who had not received any prior treatment for this condition. We randomly assigned them to two groups of 10: group one received aflibercept and group two received bevacizumab as intravitreal injections under aseptic conditions. We excluded 2 patients who did not meet the criteria and ended up with two groups of 9 patients who received monocular treatment. We gave the patients 3 monthly injections of anti-VEGF agent and followed them up at 1 month, 3 months, and 9 months after the treatment. We assessed their visual acuity, intraocular pressure and OCT appearance at each follow-up visit. The primary outcome was visual acuity. All 18 patients included in the study reported an improvement in visual acuity after the intervention. When comparing the two anti-VEGF agents, data revealed the effect of aflibercept was prompter and more long-lasting. Areas of retinal ischemia appeared in both cases. However, they were observed faster in the case of patients treated with aflibercept. Thus, neovascular AMD is a disease that occurs with age, it can be early detected by OCT and slowed the progression to central blindness with intravitreal treatment.

RESUMO

Aim: The aim of this study was to show the efficacy of intravitreal treatment with Bevacizumab (Avastin) in patients with secondary neovascular glaucoma, in different stages of the disease. Method: A retrospective study was performed on 67 patients with neovascular glaucoma. The main parameters evaluated were the patients' history, slit lamp examination, visual acuity, ocular tonometry, fundus examination, gonioscopy, and visual field. Results: It was observed that the pathology had a preponderance in males of the 6th decade, with frequently unilateral damage. Patients were referred to an ophthalmologist when the diseases reached an advanced stage, usually when the visual acuity had no light perception and the intraocular pressure was over 45 mmHg. However, the treatment with Avastin intravitreal showed a good evolution, with regression of neovessels in the first 4-7 days and maintenance of intraocular pressure within normal limits in about 60% of cases, 3 months after injection. Conclusion: The most effective treatment in secondary neovascular glaucoma is the correct therapy of the main disease. The association of Avastin and laser photocoagulation leads to regression in iris and retinal neovessels.

RESUMO

Introduction: Advances in technology and technique have led to a significant improvement in the prognosis after cataract surgery. However, there are complications that can significantly affect this prognosis, such as posterior capsule rupture and corneal decompensation. For vitreous prolapse associated with posterior capsule rupture, classic or pars plana anterior vitrectomy is required. Aim: The aim of the study was to compare corneal endothelial cell destruction after cataract surgery associated with posterior capsule rupture and classical and pars plana anterior vitrectomy, respectively. Material and method: The study was prospective, on 12 consecutive cases of cataract surgery associated with posterior capsule rupture. Classical anterior vitrectomy was performed in group A, with 5 patients, while pars plana anterior vitrectomy was performed in group B. For all cases, the Stellaris phacoemulsification device (Baush & Lomb, tm) and the associated vitrectomy device was used. Results: Pars plana anterior vitrectomy had a statistically significant lower rate of corneal endothelial damage, both in absolute value and as a percentage of initial density. Conclusions: Pars plana anterior surgery is a somewhat unfamiliar technique for anterior pole surgeons. But it is easy to learn and brings a decrease in the rate of damage to the corneal endothelium.
