Spherical Refractive error (Rx) has been reported to be reliably estimated with Ocular Biometrics (OB) using intra-ocular lens calculation method such as SRK/T formula [1]. Further supplementary data was presented regarding the evaluation of the extent of Rx alterations with Axial Length (AL) elongation using this calculation method.Rx were calculated using intraocular lens power (IOL) (22.5D A-Constant 118) and various AL (23.0 to 26.0 mm) and corneal curvature (K) readings (41.00 to 44.00 D) using SRK/T formula. IOL was estimated with Rx (Plano), AL (23.2 mm) and K reading (42.00 D).
有报道称,利用眼生物识别技术(Ocular biometics, OB),利用SRK/T公式等眼内晶状体计算方法,可以可靠地估算出球面屈光不正(Spherical Refractive error, Rx)[1]。进一步的补充数据提出了关于评估Rx改变的程度与轴向长度(AL)伸长率使用这种计算方法。Rx采用SRK/T公式计算人工晶状体度数(IOL) (22.5D - constant 118)、各种AL (23.0 ~ 26.0 mm)和角膜曲率(K)读数(41.00 ~ 44.00 D)。通过Rx (Plano)、AL (23.2 mm)和K读数(42.00 D)估计IOL。

The pathology of the elderly is the direct result of the aging process, aggravated by the physical and mental involution that occurs with advancing age. Age-related eye changes are present, such as: presbyopia, decreased tears, peripheral visual field reduction, vitreous liquefaction (with posterior vitreous detachment and retinal detachment), decreased vision due to cataracts, glaucoma, diabetic retinopathy, macular lesions, Age-Related Macular Degeneration (AMD), optic atrophy. At the same time, there are multiple systemic diseases in the elderly, at the cardiovascular, respiratory, locomotor, neurological, auditory level. The diseases of the elderly can be multiple, with a long, chronic evolution, with periods of exacerbation, frequent complications, prolonged convalescence. Aging is a continuous, dynamic process that must be followed because in its evolution new connections and balances are created that must be identified and treated properly, old age being a distinct stage of ontogenesis that should not be seen as a state of disease. In an elderly patient, the normal aging should be differentiated from pathology.
老年人的病理是衰老过程的直接结果,随着年龄的增长,身体和精神上的退化会加剧。存在与年龄相关的眼部变化,如:老花眼、泪液减少、周围视野缩小、玻璃体液化(伴有后玻璃体脱离和视网膜脱离)、白内障、青光眼、糖尿病视网膜病变、黄斑病变、年龄相关性黄斑变性(AMD)、视神经萎缩。同时,老年人还存在心血管、呼吸、运动、神经、听觉等多种全身性疾病。老年人的疾病可以是多重的,具有长期的慢性演变,有加重期,并发症频繁,恢复期延长。衰老是一个持续的、动态的过程,必须遵循这个过程,因为在它的进化过程中,新的联系和平衡被创造出来,必须被识别和正确对待,老年是个体发育的一个独特阶段,不应该被视为一种疾病状态。在老年患者中,应将正常衰老与病理区分开来。

Background: Penetrating Keratoplasty with cataract extraction and Intraocular Lens (IOL) implantation (Triple procedure) is very challenging procedure because in cases of Opaque cornea, status of anterior segment is difficult to predict that can lead to intraoperative surprises. If not managed properly, these can severely affect visual outcome. To avoid this, we performed Ultrasound Biomicroscopy (UBM) preoperatively for detailed analysis of anterior segment structures and associated pathologies and later compared it with intraoperative findings to judge predictive accuracy of UBM in guiding surgical strategies, decision making and modifications intraoperatively.Methods and findings: 20 eyes of 20 patients with different grades of corneal opacities like simple corneal opacities (6 eyes) or adherent leucoma (7 eyes) or anterior staphyloma (7 eyes) that underwent Triple procedure (Penetrating Keratoplasty+ cataract extraction+ IOL implantation) were evaluated preoperatively by UBM and the findings were compared intraoperatively to find predictive accuracy of UBM. Extent and depth of corneal lesions, corneal thickness, anterior chamber depth, type, position and extent of synechiae, pupillary membrane and status of lens and capsule were assessed. Scan was performed to visualize any posterior segment pathology and to find Axial Length (AL). Keratometry readings of other eye were taken to calculate IOL power for implantation. Preoperative UBM findings when co-related intraoperatively was found to be accurate in 71.42%- 100% parameters and accordingly these cases underwent penetrating Keratoplasty with other modifications like Iridectomy, Membranectomy, Synechiolysis, iris reconstruction, Trabeculectomy, cataract extraction and IOL implantation.Conclusion: In cataract coexisting with corneal pathologies, UBM is Best and reliable guide in predicting and preplanning of surgical strategies for best visual outcomes.
背景:穿透性角膜移植术联合白内障摘出和人工晶状体植入术(三联手术)是一个非常具有挑战性的手术,因为在角膜不透明的情况下,前段的状态难以预测,可能导致术中意外。如果处理不当,这些会严重影响视力。为了避免这种情况,我们术前进行超声生物显微镜(UBM)详细分析前节段结构和相关病理,并将其与术中发现进行比较,以判断UBM在指导手术策略、决策和术中修改方面的预测准确性。方法与结果:对20例不同程度角膜混浊(单纯性角膜混浊(6眼)、附着性白斑(7眼)、前葡萄肿(7眼)患者行穿透性角膜移植术+白内障摘出+人工晶状体植入术)三联手术的20只眼进行术前UBM评估,术中比较UBM预测的准确性。评估角膜病变的范围和深度、角膜厚度、前房深度、粘连的类型、位置和范围、瞳孔膜以及晶状体和囊的状态。进行扫描以显示任何后段病理并发现轴向长度(AL)。取另一只眼的角膜度数计算人工晶体植入术度数。术前UBM发现术中相关参数的准确性为71.42%- 100%,因此这些病例接受穿透性角膜移植术,并进行其他修改,如虹膜切除术、膜切除术、松解术、虹膜重建术、小梁切除术、白内障摘除术和人工晶状体植入术。结论:对于合并角膜病变的白内障,UBM是预测和预先规划手术策略的最佳可靠指南,可获得最佳视力效果。

A 13-year-old female reported a one-year history of hemolacria in her left eye following an episode of a migraine attack and anger outburst. Ophthalmic examination revealed inferior fornix follicles with petechia and absent inflammatory reaction. The patient was treated with topical antibiotics, steroids followed by topical 1% cyclosporine and vitamin C. Bloody tear symptoms resolved and no bloody tear was observed for the three months insinuating that conjunctival folliculosis should be considered in the differential diagnosis of hemolacria and entity needs to be differentiated from follicular conjunctivitis. Through this case report we would like to emphasize the importance of the conjunctival folliculosis identification and possibility of shedding a bloody tear in presence of vascular dysfunction. Therefore, necessitate treatment of the benign entity similar to reactive lymphoid hyperplasia.
一名13岁女性报告在偏头痛发作和愤怒爆发后左眼积血一年。眼科检查发现下穹窿卵泡有瘀点,无炎症反应。患者局部应用抗生素、类固醇,随后局部应用1%环孢素和维生素c。出血撕裂症状消失,3个月未见出血撕裂,提示结膜滤泡病在鉴别诊断时应考虑溶血性出血,实体性需要与滤泡性结膜炎鉴别。通过本病例报告,我们想强调结膜滤泡病鉴定的重要性,以及血管功能障碍时出血的可能性。因此,有必要治疗类似反应性淋巴样增生的良性实体。

Optic nerve neuropathy due to dental lesions is rare but causes complex persistent functional disorders that are difficult to diagnose. The aim of this case report is to show odontogenic optic neuropathy through treatment tactics and observation of structural dynamics and functional changes of the optic nerve with the help of a clinical case. The consultation of the patient was done as per the Department of Ophthalmology, Ivano-Frankivsk National University, Ukraine. Tests such as computed perimetry, Optically Coherent Tomography (OCT) of the optic nerve, Magnetic Resonance Imaging (MRI) of the brain, Computed Tomography (CT) of the paranasal sinuses and immunological blood tests were performed. The patient gave informed consent to access personal data and use it for scientific purposes. In the case of patient S., the combination of neuritis with lesions of the anterior part of the vascular tract is attributed to the background of multiple caries and prolapse of the teeth of the upper jaw in the sinus. Treatment includes a regimen by a dentist for caries and pulse therapy with corticosteroids. From the result, it was possible to reduce the swelling in the nerve fibers of the right eye by 35% and the left eye by 19%. The average sensitivity threshold in the right eye increased by 79% and in the left eye by 90%. In conclusion, we confirm that odontogenic optic neuropathy is a rare form of optic nerve damage. Two-stage treatment (dental and corticosteroids) reduces the nerve fibers swelling and increases retinal ganglion cells sensitivity.
视神经病变由于牙病变是罕见的,但引起复杂的持续功能障碍,是难以诊断。本病例报告的目的是通过治疗策略和观察视神经的结构动力学和功能变化,并结合一个临床病例来显示牙源性视神经病变。根据乌克兰伊万诺-弗兰科夫斯克国立大学眼科对患者进行会诊。进行了计算机视野检查、视神经光学相干断层扫描(OCT)、脑磁共振成像(MRI)、鼻窦计算机断层扫描(CT)和免疫血液检查等检查。患者知情同意访问个人数据并将其用于科学目的。在患者S.的病例中,神经炎合并血管束前部病变归因于上颌窦内多发龋和牙齿脱垂的背景。治疗方法包括牙医治疗龋齿和皮质类固醇脉冲疗法。从结果来看,右眼和左眼的神经纤维肿胀分别减少了35%和19%。右眼的平均敏感度阈值提高了79%,左眼提高了90%。总之,我们确认牙源性视神经病变是一种罕见的视神经损伤形式。两阶段治疗(牙科和皮质类固醇)减少神经纤维肿胀,增加视网膜神经节细胞的敏感性。

Isolated Foveal Hypoplasia Assessed by Multi-Focal Electroretinogram: A Clinical Presentation 多焦点视网膜电图评估孤立性中央凹发育不全:临床表现
Pub Date : 2022-05-27 DOI: 10.46889/joar.2022.3201

Foveal hypoplasia is a term commonly used to describe the lack of development or underdevelopment of the foveal pit which anatomically and functionally correlates with a region of high visual acuity. Despite the fact that, fovea facilitates more precise and greater visual processing, the absence of foveal pit does not mean, a priori, poor visual acuity. While foveal hypoplasia has been usually associated with variable ocular abnormalities, isolated foveal hypoplasia though rare, has been also described. We present a case of a 31 year-old Caucasian male with an isolated foveal hypoplasia and the clinical evaluation in combination with the imaging findings, documented by multifocal ERG for the first time in literature.
中央凹发育不全是一个通常用来描述中央凹发育不足的术语,从解剖学和功能上讲,中央凹与高视力区域相关。尽管中央凹有助于更精确和更大的视觉处理,但没有中央凹并不意味着先天的视力差。虽然中央凹发育不全通常与各种眼部异常有关,但孤立的中央凹发育不全虽然罕见,但也有报道。我们报告一例31岁白人男性孤立性中央凹发育不全的病例,并结合临床评估和影像学结果,在文献中首次通过多灶ERG记录。

Objective Spherical Refractive Error Estimation Using Ocular Biometrics 目的利用眼生物识别技术估计球面屈光不正
Pub Date : 2022-04-30 DOI: 10.46889/joar.2022.3106

Objective: To investigate the potential of clinical application spherical refractive error (SpRx) estimation using Ocular Biometrics (OB).Methods: 28 children aged from 6 to 14 years old with inter-ocular SpRx difference between 1 to 2 Dioptres (D) were recruited. Both eyes were measured with non-cycloplegia subjective refraction. OB was performed by the IOLMaster 700 (Carl Zeiss Meditec, Jena, Germany). For OB SpRx estimation, right eye Intraocular Lens Power (IOL), (A constant 118) was taken with right eye SpRx, the flattest central corneal curvature (FK) and Axial Length (AL) using SRK/T formula. Left eye OB SpRx was taken using identical calculation with right eye IOL, left eye FK and AL respectively.Results: No statistically inter-ocular differences were observed of the average FK (p=0.84) and average lens thickness (p=0.88), but not average AL (p<0.01). Average left eye SpRx by OB estimation and subjective refraction were determined as -2.86±1.02D and -2.82 ±1.16D (mean±SD) respectively. No significantly difference (p=0.84) and highly correlation (r=0.94. p<0.01) were found.Conclusion: Objective SpRx appears to be reliably estimated using OB. It likely provides a crucial SpRx reference for comparison with subjective refraction. OB SpRx may also play a vital role for monitoring the children myopic progression.
目的:探讨利用眼生物识别技术(OB)估计球面屈光不正(SpRx)的临床应用潜力。方法:招募年龄在6 ~ 14岁,眼间SpRx差在1 ~ 2屈光度(D)之间的儿童28例。双眼均采用非睫状体麻痹性主观屈光测量。OB由IOLMaster 700 (Carl Zeiss Meditec, Jena, Germany)完成。对于OB SpRx的估计,使用SRK/T公式,以右眼SpRx、最平坦的角膜中央曲率(FK)和轴向长度(AL)测量右眼人工晶状体度数(A常数118)。左眼OB SpRx分别与右眼IOL、左眼FK、AL计算相同。结果:眼间平均FK (p=0.84)、平均晶状体厚度(p=0.88)无统计学差异,平均AL无统计学差异(p<0.01)。经OB估计的平均左眼SpRx和主观屈光分别为-2.86±1.02 2d和-2.82±1.16D (mean±SD)。差异无统计学意义(p=0.84),高度相关(r=0.94)。P <0.01)。结论:OB可可靠地估计客观屈光度,为与主观屈光度的比较提供了重要的参考依据。OB SpRx也可能在监测儿童近视进展中发挥重要作用。
