Traumatic dislocation of crystalline lens with secondary glaucoma

Purpose. To analyze the patients with secondary dislocation of CTR and IOL within 5 years from cataract surgery, to determine predisposing factors.Methods. 16 eyes of 15 patients aged66.2±6.7(from 49 to 82) with CTR/IOL complex dislocation within 5 years from cataract surgery were compared with 26 patients aged67.1±7.2(from 53 to 85), implanted with CTR during cataract surgery to manage zonule dehiscence and did not dislocate for at least 5 years, in respect of cause, axial length and IOL power, refraction, coexistent pathology, and trauma.Results. Axial length of the eyeball was23.8±1.3(from 21 to 29) in the group of patients with CTR/IOL dislocation and20.7±1.2(from 19 to 24) in patients with no dislocation present (p=0.008). Crystalline lens dislocation was diagnosed before surgery in 13 of 16 patients with CTR/IOL complex dislocation as opposed to 7 of 26 eyes in the control group (p=0.01). Pseudoexfoliation was present in 50% and 58% in both groups, respectively. Traumatic dislocation was present in 8 patients, none of them with CTR/IOL dislocation (p=0.04).Conclusion. Longer axial length may contribute to the failure of the CTR to prevent in-the-bag IOL dislocation. Traumatic dislocation appears to be well fixed with the CTR.

Pars Plana

Pars plana vitrectomy (PPV) is currently used as an effective method in many posterior segment pathologies. Although the most common indication is retina and vitreous pathologies, PPV is also preferred in some cases associated with lens and glaucoma. In case the crystalline lens or artificial intraocular lens, which is a product of industrial development, falls into the vitreous, it is essential to remove it mostly with the PPV approach. In some types of secondary glaucoma, especially malignant glaucoma, successful results are obtained in terms of visual prognosis and complications with vitreoretinal surgery techniques.

Secondary Glaucoma

Актуальность. Частота встречаемости сочетания ретинопатии недоношенных (РН) IV – V стадии с глаукомой составляет до 33,0%. Актуальным является то, что активные оперированные стадии РН сопровождаются развитием вторичной глаукомы, ухудшающей прогноз течения основного заболевания. Цель. Продемонстрировать клинический случай бомбажа радужки на фоне вторичной глаукомы у пациента с РН в анамнезе. Материал и методы. Пациент 4 месяцев жизни с диагнозом: (Н35.2) OD - РН V стадии, «задняя агрессивная форма», оперированная. (Н27.0) OD афакия, авитрия. (Н40.5) OD глаукома вторичная. (Н21.2) OD дегенерация радужной оболочки. (Н35.2) OS - РН IV Б - V стадии, «задняя агрессивная форма», оперированная, прогрессирование заболевания в виде нарастания отслойки сетчатки. (Н27.0) OS авитрия. Результаты. Пациенту провели оперативное лечение в объеме интравитреальной иньекции ингибитора СЭФР в оба глаза, после которого отмечалась положительная динамика в виде уменьшения патологической активности сосудов, нивелирования экссудативно-геморрагического компонента, стабилизации показателей тонометрии. Выводы. 1. Вторичная глаукома - осложнение тяжелой формы РН приводит к необратимой потере зрительных функций и органа зрения, инвалидизирующее в раннем детском возрасте. 2. Интравитреальная инъекция ингибитора СЭФР при агрессивных пролиферативных процессах позволяет стабилизировать состояние патологических внутриглазных процессов. 3. Клинический случай демонстрирует возможность стабилизации ВГД, пролиферативно-экссудативных процессов, остановку безвозвратных внутриглазных разрушений структур глаза, приводящие к удалению глазного яблока.

Purpose. To study the effectiveness of extrascleral filling (ESF) using endoillumination in the surgical treatment of patients with primary rhegmatogenous retinal detachment (RRD). Material and methods. The material for the study was the data of a comprehensive clinical examination and surgical treatment by ESF method using endoillumination in 17 patients (17 eyes) with RRD. In 7 cases (41%), the macular area was involved in the detachment process. In 5 cases (29.4%), local scleral filling was performed. In the remaining 12 cases (70.6%), the local ESF was supplemented with a circling silicone element. Surgical intervention was supplemented by transscleral drainage of subretinal fluid (SRF) in 10 cases (59%) and pneumatic retinopexy with SF6 gas 50% in 8 cases (48%). Results. In the general group of patients, best corrected visual acuity (BCVA) increased from 0.35 to 0.46. In the subgroup of patients with a detached macular area, the positive dynamics is more pronounced, BCVA increased from 0.1 to 0.28. The progression of proliferative vitreoretinopathy caused the recurrence of retinal detachment in two patients (11.8%). Recurrences were diagnosed after 3 and 5 months, respectively. In both cases, a vitrectomy with tamponade of the vitreous cavity with silicone oil 5000 Cst was performed. The percentage of successful anatomical outcome after the first operation in our study was 82%. The percentage of successful achievement of the final anatomical result was 94%. In two cases, additional injection of SF6 gas into the vitreous cavity was required. Conclusion. This type of surgical treatment is an effective method of surgical treatment of patients with RRD. In our study, the successful anatomical outcome after the first operation was recorded in 82% of patients, which correlates with the data of the authors who also used this method (83–92%). Surgeons who performed surgical treatment using this technique in our study note improved workplace ergonomics when visualizing the fundus using an operating microscope and endoillumination compared with indirect ophthalmoscopy. Other teams of authors came to this conclusion as well. In our study, there were no complications associated with the introduction of a light pipe into the vitreous cavity (iatrogenic crystalline lens injury, endophthalmitis), which indicates the safety of this type of surgical treatment.
