Purpose. To evaluate the effectiveness of surgical resection of the sclera in patients with primary open-angle and secondary glaucoma. Materials and methods. The study included 84 patients with POAG and SG stages III-IV and decompensated IOP level (not higher than 32 mm Hg). In order to normalize the increased ophthalmotonus, a non - penetrating operation was performed-surgical resection of the sclera (SRS). The patients underwent complex ophthalmological examination and dynamic observation. Result. In the studied groups of patients after surgical treatment there was a decrease in elevated IOP levels by 33.42%, an improvement in the coefficient of ease of outflow and a weakening of the hypotensive regime. Stabilization of visual functions was observed in all patients. Summary. The proposed new SRS technique provides a smooth decrease in IOP, preservation of visual functions and is not accompanied by intra-and postoperative complications. Key words: primary open-angle glaucoma, surgical resection of sclera, secondary glaucoma, uveoscleral outflow pathway (USPO), intraocular pressure, EO coefficient .

Aim: to assess clinical efficacy and safety of surgical scleral rejection (SSR) vs. transscleral diode laser cyclophotocoagulation (TSCPC) in primary open-angle glaucoma (POAG) and secondary glaucoma (SG). Patients and Methods: study (prospective) group included 84 patients with POAG and SG after SSR. Control (retrospective) group included 80 patients after TSCPC. In addition, the patients were distributed by age and the stage and type of glaucoma, i.e., 128 patients were diagnosed with POAG and 36 patients were diagnosed with secondary thrombotic glaucoma. Follow-up was 24 to 36 months. IOP measurements, tonography (to assess the coefficient outflow facility / COF), ultrasound biomicroscopy of the anterior segment, visual acuity measurement, and visual field testing were performed. Results: no complications after SSR were reported in patients with POAG and SG. In contrast, postoperative complications (choroidal effusion, hyphema, and uveitis) were reported in 14% of patients after TSCPC. Long-term IOP-lowering efficacy of both procedures was similar (87% after SSR and 89% after TSCPC). In POAG, greater IOP reduction was seen after TSCPC (by 39.11%) compared to SSR (by 31.58%) (p<0.05). Meanwhile, in patients with SG, treatment outcomes were similar (IOP reduced by 36.78% after TSCPC and by 35.26% after SSR). In longterm follow-up, PVF reduced by 10.76% vs. baseline after TSCPC but increased by 11.19% vs. baseline after SSR (p≤0.05). Surgery resulted in the improvement or stabilization of visual functions. Ultrasonography has demonstrated that outflow pathways (intrascleral space and filtering bleb) remain functional after SSR in long-term follow-up. Conclusion: SSR is an alternative to cyclodestructive procedures in POAG and SG. Sclera being the final point of the uveoscleral outflow is a perspective entity to develop surgical approaches to glaucoma treatment.

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.

Background: Glaucoma is an important cause of blindness. Objective: To report the distribution of various types of glaucoma among patients presenting to a tertiary eye hospital in Nepal. Materials and methods: All new patients visiting the hospital between March 2007 and February 2008 underwent a comprehensive eye examination. Whenever glaucoma was suspected, patients were referred to fellowship-trained glaucoma specialists. Patients received a comprehensive glaucoma workup including applanation tonometry, stereoscopic examination of the optic nerve head performed by the glaucoma specialists, and a Humphrey visual field analysis (SITA 24 - 2). Results: 447 patients were newly diagnosed with glaucoma. 171 (38.2 %) patients had primary open-angle glaucoma (POAG), while 143 (32 %) had primary angle-closure glaucoma (PACG). The average age of presentation of patients with POAG was 65.78 ± 9.1 years, while the average age for PACG patients was 54.6 ±12.8 years. 30 (21 %) patients with PACG had acute angle-closure on presentation, while 113 (79 %) had chronic angle closure glaucoma. 107 (75 %) of these patients with PACG had visual acuity of less than 3/60 (20/ 400) in the worse eye at presentation. The most common form of secondary glaucoma was lens-induced (5.3 %), followed by neovascular (3.2 %) and uveitic glaucoma (3.2 %). Conclusion: The most common glaucoma seen in a tertiary referral eye hospital of Nepal is primary open-angle glaucoma. Among the angle-closure glaucoma, chronic angle-closure is the most common. Lens-induced glaucoma is still the commonest cause of secondary glaucoma.

Objective: To evaluate changes in intraocular pressure after congenital cataract surgery in a real-world setting. Methods: This retrospective case series included all children aged 0–2 years undergoing lens extraction due to congenital cataract. Development of an elevated intraocular pressure was divided into three groups: secG, suspG and OHT. Further, risk factors for IOP changes, the therapeutic approach and functional outcome were assessed during follow-up. Results: One hundred and sixty-one eyes of 110 patients aged 0–2 years were included, whereof 29 eyes of 17 children developed secondary glaucoma (secG; 11 eyes/8 patients), glaucoma suspect (suspG; three eyes/three patients) or ocular hypertension (OHT; 15 eyes/10 patients). No difference in surgrical procedure ( p = 0.62) was found, but age at cataract surgery differed significantly ( p = 0.048), with the secG group (1.74 ± 1.01 months) being the youngest (suspG: 3.93 ± 1.80 months; OHT group: 5.91 ± 5.36 months). Secondary surgical intervention was significantly higher in the secG (4.64 ± 3.41) followed by the suspG (2.00 ± 2.65) and OHT groups (0.40 ± 0.74; p < 0.001). Postoperative complications including nystagmus ( p = 0.81), strabismus ( p = 0.98) and amblyopia ( p = 0.73) showed no difference, in contrast to visual axis obscuration which was more common in the secG group ( p = 0.036). Conclusion: Initial lensectomy and anterior vitrectomy procedure together with or without IOL implantation seems to have no influence for the development of IOP changes after pediatric cataract surgery. However, children who developed secondary glaucoma had cataract surgery significantly earlier, within the first 2–3 months of life. Glaucoma surgery was required to achieve final IOP control in most eyes. The development of secondary glaucoma was also associated with a significant increase in surgical re-treatments.

Implantable collamer lenses (ICL) have gained popularity for correction of myopia where kerato-refractive procedures are not indicated as in cases of high myopic refractive errors. Toxic anterior segment syndrome (TASS) is a very uncommonly reported postoperative complication following ICL implantation. A young patient developed severe corneal oedema and anterior segment inflammation on the first day after ICL implantation. Analysing retrospectively, possible idiosyncratic response to intracameral pilocarpine was considered as a cause for TASS. Prompt and intensive therapy with oral and topical potent steroids was visually rewarding. TASS, though a sterile inflammation can have catastrophic sequelae such as corneal decompensation and secondary glaucoma. Hence, timely identification and management is important.
