“To Fulfill two needs with one deed”: Iris fixation of intraocular lens using four-throw pupilloplasty

Background: Pupil distortion and aphakia are common complications that follow blunt injury of the eye globe, surgical complications, and iris coloboma. Patients with these two complications complain of severe glare and photophobia even after successful intraocular lens (IOL) implantation like scleral fixation of intraocular lens (SFIOL) due to irregular pupil. To overcome this, we prefer to do pupilloplasty along with IOL implantation. Purpose: In this video, we demonstrate iris fixation of IOL using four?throw pupilloplasty; thus with one surgical technique, both pupilloplasty and iris fixation are done. Synopsis: The technique of an IOL implantation without capsular support can be challenging. There are different techniques, such as iris claw, iris fixation, and scleral fixation. Permanent mydriasis or distorted pupil can be a disabling condition, even after successful vision gain, due to photophobia. So pupilloplasty is nowadays preferred along with IOL implantation. Usually after IOL implantation, iris cerclage or pupilloplasty is done. We combined both steps with one technique: iris fixation with four?throw pupilloplasty. This technique can be used for iris coloboma with weak zonules and surgical iridectomy with aphakia cases where the pupil is irregular. Highlights: The video highlights the steps of four?throw pupilloplasty technique which is also used for fixating the IOL to the iris (iris fixation). This can give an excellent outcome in aphakia with distorted pupil using a single technique approach.

Analysis of hesitancy and motivational factors for COVID-19 vaccination among patients presenting to eye care hospitals – A multicenter questionnaire-based survey

Purpose: To analyze the hesitancy and motivational factors related to coronavirus disease 2019 (COVID?19) vaccination among patients visiting for eye care. Methods: A telephonic survey was conducted using validated questionnaires consisting of 36 questions in five sections from July 1 to July 31, 2021. Patients visiting six tertiary centers and one secondary center of our eye hospitals were interviewed over their phones, and their responses were entered onto the Google forms. The responses were recorded as demographics, health status, awareness about vaccination, factors contributing to hesitancy or acceptance to vaccinate, and general perception about the vaccine. Results: A total of 5033 patients were surveyed. The mean age was 49.0 ± 14.2 years. A total of 563 (11.2%) patients gave a history of symptoms or were tested positive for COVID?19; 2225 (44.2%) patients were already COVID?19 vaccinated. Around 2883 (56%) patients were aware of getting infection despite vaccination, and 4092 (81.3%) perceived vaccination should be compulsory. The main reason for vaccination hesitancy was the fear of side effects (n = 487, 17.3%). The fear of getting infected was the most common reason for vaccination (n = 911, 40.9%). Factors associated with a lower proportion of vaccinated individuals included younger age (P < 0.001), female gender (P < 0.001), lower education (P < 0.001), lower income (P < 0.001), and rural residence (P = 0.33). Conclusion: Creating awareness about the minor side effects and reassurance can allay an individual’s fears. The fear associated with the rapid spread of infection and associated mortality needs to be utilized to increase vaccination acceptance. A targeted approach toward groups with poor uptake of vaccination is necessary.

We found this technique of digital retinoscopy to be useful for demonstrating and documenting retinoscopic reflexes and in addition as an easy teaching tool. This technical report explains the assembly of our smartphone-assisted retinoscope and provides examples of the range of normal and abnormal reflexes that can be captured.

Potpourri of retinopathies in rare eye disease – A case series

This case series describes the ocular and retinal manifestations of rare eye diseases in systemic syndromes. This observational case series consists of five patients with varied ophthalmic manifestations and documentation of imaging in rare pediatric and adult retinopathies. Two patients had Kearns Sayre syndrome (KSS) based on the classical triad of external ophthalmoplegia, pigmentary retinopathy, and onset before 20 years of age. In one patient of KSS, the mitochondrial retinopathy was seen in an asymmetric pattern, and the second patient presented with KSS after being mis-diagnosed as myasthenia gravis elsewhere. A case of Senior Loken syndrome in pediatric age is described in this series with varied ophthalmic manifestations ranging from retinitis pigmentosa to orbital abscess. This series also enlightens features of Hallervorden Spatz syndrome presenting with bull’s eye maculopathy and a case of spino-cerebellar ataxia type 7 presenting with pigmentary retinopathy.

PHACOSIT: A sitting phacoemulsification technique for patients unable to lie down flat during cataract surgery

Phacoemulsification is routinely performed with the patient lying supine on the surgical table with his or her head flat and facing the overhead microscope. This routine technique can be a challenge in medical conditions such as kyphosis, scoliosis, orthopnea, Meniere抯 disease, and CNS abnormality. Some cardiovascular and respiratory conditions make the patients breathless when they lie down, whereas other neurological and spinal problem patients are also equally uncomfortable. The only reasonable solution to conduct surgery on a patient who cannot lie down flat on the operating table is to position them face to face in a sitting position. We describe an innovative phacoemulsification technique in a sitting position called 損hacosit� in an 80?year?old wheelchair?bound female patient who was denied cataract surgery by other eye surgeons owing to her medical condition.

Slit-lamp based intraocular lens microscope - A novel technique of rapid office-based microscopy

The emergence of smartphone?based imaging devices has been a boon in the field of ophthalmology, especially in obtaining high?quality ocular images. They can be specialized and utilized for imaging?specific regions of the eye. Among the multitude of applications of smartphone?based imaging, one of the upcoming major use is to image the microbiological world. Previous few reports have described attaching magnifying lenses of various types to the smartphone camera and transforming it into a microscope for imaging fungal hyphae and ocular surface parasites. We describe a novel technique of attaching the smartphone?based intraocular lens microscope (IOLSCOPE) to the slit lamp, thereby utilizing the slit lamp joystick for moving the smartphone over the concerned slide specimen to make it steady and obtain images of high resolution. This innovative do?it?yourself novel modification is especially useful in peripheral centers, vision centers, and local clinics for immediate screening and identification of microbial pathogens such as fungi and ocular surface parasites.

Prisms in the treatment of diplopia with strabismus of various etiologies

Purpose: We aimed to study the success of prism in regard to diplopia resolution score and associated factors in patients presenting with symptomatic diplopia arising from various etiologies. Methods: In this descriptive, retrospective study diplopia resolution among 31 patients who were prescribed prism were analyzed. Results: Fifty?four patients were evaluated for diplopia and 31 were included for the study done over 3 years. The mean follow?up was 15 months. Esotropia, exotropia, and hypertropia were seen in 39%, 51%, and 19.4% of patients, respectively. Furthermore, 71% received Fresnel prism and 29% were given ground glass prism. The mean prism power prescribed was 13.3 PD. 87% had complete resolution of diplopia; 96.8% continued usage of prism. High success rates were seen among patients with decompensated strabismus, sixth and fourth nerve palsy. Horizontal prism and oblique prism in the form of Fresnel prism yielded complete resolution of diplopia (P = 0.028). There was no association between the success of prism and etiology (P 0.058), history of trauma (P = 0.212), and type of deviation (P = 0.387). The study showed that oblique Fresnel prism can be considered for combined deviation. Conclusion: Our study showed prism to be effective in alleviating diplopia over a varied range of etiologies

Synergistic convergence and split pons in horizontal gaze palsy and progressive scoliosis in two sisters.

Synergistic convergence is an ocular motor anomaly where on attempted abduction or on attempted horizontal gaze, both the eyes converge. It has been related to peripheral causes such as congenital fibrosis of extraocular muscles (CFEOM), congenital cranial dysinnervation syndrome, ocular misinnervation or rarely central causes like horizontal gaze palsy with progressive scoliosis, brain stem dysplasia. We hereby report the occurrence of synergistic convergence in two sisters. Both of them also had kyphoscoliosis. Magnetic resonance imaging (MRI) brain and spine in both the patients showed signs of brain stem dysplasia (split pons sign) differing in degree (younger sister had more marked changes).

Intravitreal bevacizumab (Avastin) for post laser anterior segment ischemia in aggressive posterior retinopathy of prematurity.

Aggressive posterior retinopathy of prematurity (formerly known as fulminate/type II/rush disease) occurs in zone 1 or posterior zone 2. Treatment involves extensive near confluent laser ablation of a large area of avascular retina. Anterior segment ischemia is a rare complication that can occur due to injury to the long posterior ciliary arteries in the horizontal meridians during aggressive posterior laser treatment. The outcome of this rare complication is very poor. This case describes a favorable outcome of intravitreal injection of bevacizumab (Avastin) in a case of anterior segment ischemia.
